Families change. Your home needs to change, too. What once felt spacious might start to feel cramped as children get older and lifestyles evolve. For many homeowners, especially those in historic Michigan neighborhoods, moving isn’t always the solution. Instead, thoughtful room addition ideas can help Michigan families create the space they need while staying rooted in the home and community they love.
Room additions offer flexibility, long-term value, and the opportunity to tailor a home to your family’s unique needs. Maybe you need an additional bedroom or want a larger entertainment space. Whatever the goal, the right addition can make everyday life in your home feel more comfortable and manageable.
Why So Many Michigan Families Opt for Room Additions
Space needs can change quickly over the years. Young children may need play areas and shared bedrooms, while older kids want privacy and quiet places to study. Parents may find themselves working from home more often or caring for aging relatives. These changes place new demands on your home.
Many Michigan homes, especially those built decades ago, were not designed for today’s lifestyles. Smaller bedrooms, limited storage, and compartmentalized living areas can make daily routines feel crowded. At the same time, rising home prices and limited inventory make relocating less appealing.
Room additions allow families to respond to new demands by reshaping their current home. Instead of compromising on location or layout, homeowners can invest in space that supports how they live now and how they expect to live in the future.
How Room Additions Can Improve Daily Life and Long-Term Value
A well-planned room addition does more than increase square footage. It improves how the entire home functions and supports the way families actually live.
In daily life, the right addition can:
Reduce overcrowding by giving each family member appropriate personal space
Lower noise levels by creating separation between sleeping, working, and gathering areas
Improve organization with dedicated storage instead of makeshift solutions
Create defined zones for homework, play, relaxation, and entertaining
Make living areas feel calmer, more comfortable, and easier to use
From a long-term perspective, room additions can also:
Increase overall home value by improving layout and livability
Add bedrooms or flexible spaces that appeal to a wider range of future buyers
Make the home more adaptable as family needs change over time
Protect your investment by reducing the need for future renovations or moves
Even if selling is not part of the plan, designing a room addition with flexibility and functionality in mind helps ensure the space continues to serve your family well for years to come.
Popular Room Addition Ideas for Michigan Homes
When it comes to expanding a home, there is no one-size-fits-all solution. The most successful additions reflect how a family actually lives.
Adding Bedrooms for Kids or Guests
One of the most common reasons families explore additions is the need for more bedrooms. They might want to add a single bedroom so kids don’t have to share or add a guest room that can flex as the family’s needs change.
Thoughtful planning can include adding built-in storage, shared bathroom access, and a layout that can evolve from nurseries to teen rooms to home offices over time.
Primary Suite Additions
Many families choose to add or expand a primary suite to create separation between adult and child spaces. A larger bedroom or additional closet space can also dramatically improve the comfort and privacy of the space.
Primary suite additions are great for long-term planning, too. Wider doorways, walk-in showers, and main-level layouts make the home easier to navigate for those who wish to age in place.
Expanding Living Areas for Everyday Life
As families spend more time at home, living spaces often become the heart of daily activity. Expanding a family room or creating a great room addition can provide space for gathering, relaxing, and entertaining without feeling cramped.
These additions often improve flow between the kitchen, dining, and living areas. Open layouts allow parents to keep an eye on kids while cooking, working, or hosting friends.
Flexible Spaces That Grow With Your Family
Flexibility is key for growing families. Playrooms that eventually become teen lounges, homework rooms that transition into offices, or bonus rooms that adapt to different uses over time all offer long-term value.
Designing these spaces with neutral layouts, durable finishes, and adaptable lighting allows them to change as your family does without requiring another renovation.
Second-Story vs. Main-Level Additions: Which Works Best?
Should you build up or out? Each approach has advantages depending on the home, lot, and lifestyle.
Building up: Second-story additions are often a good solution when the lot size is limited or outdoor space is a priority. Adding space above the existing footprint can create bedrooms, bathrooms, or private retreats without sacrificing yard space. Structural evaluations and careful planning are essential, especially in older Michigan homes.
Building out: Main level additions are preferred when expanding living areas or creating primary suites. These additions can improve accessibility and flow while connecting to the existing space. They may also offer more flexibility in building height, natural light, and layout.
Michigan’s climate, zoning rules, and neighborhood character all play a role in determining the best option. An experienced design-build team can help evaluate which approach aligns with your goals and property constraints.
Planning Considerations for Family-Focused Room Additions
A successful room addition starts with thoughtful planning that looks beyond today’s needs. Taking time to evaluate these factors early helps ensure the new space supports your family both now and in the future.
Zoning and permitting requirements: Local regulations vary across Michigan communities and can influence where and how an addition can be built. Understanding setbacks, height limits, and neighborhood guidelines early helps prevent delays.
Budget planning and phasing options: Room additions are a meaningful investment. Establishing priorities, building in contingencies, and considering phased construction can help keep the project aligned with financial goals.
Living through construction: Families often remain in the home during an addition. Planning safe work zones, clear communication, and realistic timelines helps minimize disruption to daily routines.
Designing for future needs: Children grow, schedules change, and homes must adapt. Designing rooms with flexible layouts allows spaces to evolve from playrooms to bedrooms, offices, or guest spaces over time.
Energy efficiency and comfort: Proper insulation, efficient windows, and well-planned HVAC systems ensure the addition remains comfortable year-round and blends seamlessly with the existing home.
Storage and organization: Incorporating built-in storage into the addition reduces clutter and improves functionality throughout the home.
Resale value and long-term appeal: Even if you plan to stay long term, designing an addition that feels cohesive and adaptable helps protect the home’s value and appeal to future buyers.

The garage can be one of the most underutilized parts of the home. It might hold cars, seasonal storage, or boxes you haven’t opened in years. But as your lifestyle and needs change through the years, it’s possible to reimagine your garage and use that valuable square footage to its full potential. A well-planned garage conversion in Ann Arbor allows homeowners to create comfortable living spaces and enhance the functionality of their home without having to leave the house and neighborhood they love.
Whether you are running out of room now or planning for future needs, a garage conversion or addition offers a flexible solution. Learn what your options might be, what to plan for, and how to design a space that feels like an intentional, thoughtful enhancement to your current home.
Why Homeowners Are Looking at Their Garages Differently
We are asking our homes to do more than ever before. Remote work, multigenerational living, and evolving hobbies have changed how we use our spaces. At the same time, many Ann Arbor neighborhoods have limited lot sizes, so outward expansion is a challenge when you are running out of room inside.
Your garage could be hiding a lot of untapped potential. In some homes, they are used primarily for storage rather than parking. In others, they sit partially empty while interior rooms feel crowded. Converting or expanding a garage allows homeowners to reclaim square footage without dramatically altering the home’s footprint.
Rising home values also play a role. Homeowners are increasingly focused on maximizing what they already have rather than moving. When designed well, a garage conversion can feel like a natural extension of the home and add value to your home on the resale market.
Garage Conversion or Home Addition: Which Is Right for You?
A garage conversion repurposes the space you already have, while a home addition expands your home’s footprint by adding new space onto the existing structure. Both options can add valuable square footage, but they solve different problems. The right choice depends on how you live now, what you’ll need in the future, and what your property will allow.
When a Garage Conversion Makes Sense
A garage conversion is often the most efficient path when the garage is underused and you would benefit more from finished space than dedicated parking. Since the structure already exists, a conversion can streamline parts of the build and focus the investment on insulation, utilities, windows, and high-quality finishes. For many Ann Arbor homeowners, this can be a smart way to create a home office, guest suite, studio, or flex room without changing the home’s footprint.
Garage conversions are also a great fit when the home’s current layout is close to what you want, and you simply need one more functional zone. The key is making sure the converted space feels fully integrated, with proper HVAC, moisture control, and exterior updates that match the rest of the home.
When a Home Addition Is the Better Option
A home addition is often the better choice when you need more space than the garage can realistically provide, or when you want to expand core living areas like the kitchen, family room, or primary suite. Additions offer the most flexibility in layout, ceiling height, natural light, and long-term functionality. They can also preserve the garage for parking, storage, or seasonal use, which matters to many homeowners in Michigan.
In older Ann Arbor neighborhoods with tight footprints, an addition can be designed to improve flow and function throughout the home, not just add a single room. While additions typically involve more structural work and a larger budget, they also allow homeowners to build the exact space they need without compromises.
Key Questions to Help You Decide
How will the new space be used day-to-day, and will that need likely change over time?
Do you need to keep the garage for parking, storage, or winter convenience?
Is the existing garage structurally suitable to become a conditioned living space (insulation, slab condition, ceiling height)?
Would a conversion improve the flow of the home, or would it create an awkward layout?
Would an addition solve broader layout issues, like expanding a kitchen or creating a true primary suite?
What do local zoning rules and permitting requirements allow for your lot and neighborhood?
Which option fits your budget best once you account for HVAC, electrical, windows, and exterior integration?
Popular Garage Conversion Ideas in Ann Arbor
One of the most exciting aspects of a garage conversion is how adaptable the space can be. Because the space can be tailored so precisely, homeowners across Ann Arbor are finding creative ways to turn garages into rooms they use every day.
Home Offices Studios
With remote and hybrid work here to stay, garage conversions make excellent home offices. The separation from the main living areas creates a quieter environment, while thoughtful insulation, lighting, and sound control turn the space into a productive retreat. Many homeowners also use converted garages as art studios, writing rooms, or music spaces where creativity can thrive without interruption.
Guest Suites
A garage conversion can become a comfortable guest suite with a bedroom and bathroom, offering privacy for visitors or extended family. These spaces are especially appealing for multigenerational living or long-term guests, allowing everyone to have their own space while staying connected to the household.
Family Rooms
Some homeowners prefer to keep their main living spaces calm and uncluttered. Converting a garage into a family room or media lounge creates a relaxed place for movie nights, gaming, or casual gatherings without competing with everyday living areas.
Wellness Rooms
Home gyms and wellness spaces are another popular use. A converted garage can accommodate workout equipment, yoga practice, or even a sauna or recovery area. Having a dedicated space makes it easier to maintain routines without sacrificing interior living space.
Mudrooms and Functional Entry Spaces
In Michigan’s changing seasons, functional entryways matter. Garage conversions can become oversized mudrooms with built-in benches, cubbies, and storage that keep shoes, coats, and gear organized. Some homeowners pair this with laundry space to improve daily efficiency.
Hobby Rooms
From woodworking to crafting, converted garages give homeowners room to pursue hobbies that need space, storage, and durability. These rooms can be customized with reinforced floors, specialized lighting, and storage solutions designed around how the space will actually be used.
Key Planning Considerations for a Garage Conversion
A successful garage conversion depends on more than finishes and layout. Early planning around regulations, structure, and comfort ensures the new space feels like a true part of the home rather than a repurposed afterthought:
Zoning and permitting requirements:Local regulations in Ann Arbor can affect whether a garage may be converted and how the space can be used. Setbacks, parking requirements, and allowable square footage all play a role and should be confirmed early.
Insulation and climate control: Garages are typically not built to residential comfort standards. Proper wall, ceiling, and slab insulation, along with heating and cooling upgrades, are essential for year-round use.
Moisture management and waterproofing: Because garages sit at or below grade, addressing moisture is critical. Vapor barriers, drainage improvements, and slab preparation help protect finishes and indoor air quality.
Flooring upgrades: Existing concrete slabs may need leveling or additional treatment. Selecting flooring that balances durability, comfort, and moisture resistance is key to long-term performance.
Electrical capacity and lighting: Converted spaces often require additional outlets, upgraded panels, and layered lighting. Planning for these needs early avoids surface-mounted solutions later.
Plumbing considerations: If the space will include a bathroom, laundry, or wet bar, plumbing access and drainage must be evaluated during the design phase.
Ceiling height and structural elements: Some garages have lower ceilings or exposed framing that require creative solutions to meet comfort and code requirements.
Exterior integration and curb appeal: Windows, doors, siding, and trim should match the rest of the home so the conversion feels intentional and cohesive from the street.
Long-term flexibility and resale value: Designing the space to adapt to future needs helps protect your investment and keeps the home appealing to future buyers.

Adding more space to your home comes down to either building out or building up. For many Michigan homeowners, expanding upward is the most practical option. A second-story addition in Michigan can open the door to a new bedroom, larger living areas, private suites, or flexible family space without sacrificing your yard or changing the footprint of your home.
A project of this scale deserves careful planning. Second-story additions can be transformative, but they also involve structural considerations, engineering demands, and regulations that you’ll want to understand before moving forward. Let’s explore the key factors that make a second-story addition successful and what homeowners can expect from the process.
Choosing to build up is often the result of wanting more space, but not wanting to leave the home or neighborhood you love. Many Ann Arbor homes were built decades ago, so they offer incredible character but not a lot of square footage. A second-story addition allows homeowners to stay rooted in their community while investing in long-term livability.
Some families might need more bedrooms as their numbers grow or as older children need more privacy. Others might crave a home office or a primary suite that feels like a retreat. An addition can also give you space for multigenerational living, making it possible to create comfortable zones for every member of the household.
Building up also maximizes the value of your property. When outdoor areas are already established, or yard space is limited, a second story allows you to expand the function and improve the layout of your home.
Why Building a Second Story Can Be a Unique Challenge
Michigan’s climate and architectural landscape create specific considerations for homeowners and builders. Before you pursue a second-story addition, you’ll want to make sure you partner with a builder who understands the unique requirements of these projects, including:
Climate Considerations
A second-story addition must be designed with the region’s seasonal extremes in mind. Snow load, wind exposure, freeze-thaw cycles, and energy performance all shape the engineering process.
Roof design and snow load: New upper-level framing must safely support Michigan’s heavy winter snow. Structural engineers calculate load requirements and adjust roof pitch, framing size, and structural connections accordingly.
Insulation and air sealing: With more exterior walls and roof surface area, the new level must be insulated to maintain comfort and efficiency. Proper air sealing prevents heat loss and reduces the risk of ice dams on the roof.
Moisture management: Vapor barriers, flashing, and proper ventilation keep the structure dry and prevent long-term issues like mold and rot.
When done well, the new level will feel just as comfortable and energy efficient as the original home.
Structural Requirements
One of the most important steps in planning a second-story addition is understanding what the home can support. Not all existing structures are built to carry the weight of an additional level, and some require reinforcement.
Foundation evaluation: Builders must determine whether the foundation can support the added load. Some homes are well-suited for a second story from the start, while others need reinforcement or upgrades.
Load-bearing walls and structural tie-ins: Engineers analyze how weight is transferred down to the foundation and identify where reinforcements or new beams are needed.
Floor system upgrades: A second story often requires replacing or strengthening first-floor ceilings to support new joists above.
These steps ensure that the addition is not only safe but also durable for decades to come.
Local Codes & Restrictions
Every city and township in Michigan has its own zoning guidelines, and Ann Arbor is no exception. Setbacks, maximum building height, lot coverage rules, and neighborhood overlays all influence what kind of addition is possible.
A second-story addition brings architectural changes to the home’s exterior. That means the project must meet local design and safety standards. Working with a contractor who understands regional codes helps prevent delays and ensures the new structure integrates seamlessly into your neighborhood.
Cost Factors to Consider Before Building Up
A second-story addition can be one of the most substantial investments a homeowner makes. It can be helpful to know what factors influence the cost, as price varies depending on the size and complexity of the new space. Key cost drivers include:
Structural engineering and reinforcement
New roofing systems
Framing and load-bearing modifications
Staircase construction and main floor reconfiguration
Upgrades to mechanical systems, such as HVAC and electrical
Exterior finishes, including siding, trim, and window packages
Interior finishes, which range from simple to luxury grade
While the investment can be significant, building up adds considerable value to your property. You’ll increase square footage while improving the interior spaces, something that will appeal to buyers who already love your established neighborhood.
Challenges to Prepare For During a Second Story Addition
Every major remodel comes with challenges, but an experienced team can help you prepare for and manage them effectively. Knowing what to expect makes the process smoother and a lot less stressful.
Some challenges to consider include:
Living in the home during construction. Some families choose to stay in the home while the second story is being built. Most of the time, this isn’t a problem, but it does require a lot of coordination with the building team. MBK coordinates temporary protections and safe access points for the family.
Weather interruptions. Michigan weather can be unpredictable. Experienced builders like MBK know how to protect open structures and plan around seasonal conditions so work doesn’t come to a standstill.
Protection of the existing home. From dust containment to temporary ceilings, protecting the original structure is essential. A well-managed site keeps the interior clean and minimizes disruptions to the family’s daily routine.
Choose a Trusted Partner for Second Story Projects in Michigan
Adding a second story to your home is a major investment, and choosing the right team can help make sure that investment pays off. MBK Constructors brings decades of experience working on Michigan homes, including older and historic properties that require careful structural integration. Our team includes engineers, designers, and architects who craft every detail so it aligns with your ultimate vision.

An addition can add valuable and much-needed space to the home you love. It can be a great way to increase your square footage for a home office, bigger kitchen, or even a guest suite. While deciding to expand your home can be exciting, a lot of homeowners in Ann Arbor worry about juggling the architects, engineers, and contractors needed to make it happen.
A design-build home addition can make this process so much easier. This method streamlines every phase of the project by bringing architects, designers, and builders together onto one unified team. Instead of coordinating multiple companies, homeowners work with a single project manager who handles everything from concept to construction. The home addition process becomes a lot more manageable, so you can design the home you’ve always wanted, without the hassle of moving or leaving the neighborhood you love.
Design-build is a project delivery method where the same company handles both the design and construction of your home addition. You sign one contract and work with one team throughout the project. This is a different method from the traditional design-bid-build approach, where an architect designs the plans, a contractor bids on them, and a separate builder actually completes the work.
With design-build, one team collaborates on your project. Designers are aware of construction realities, and builders understand the designer’s intent, because they’ve all worked together from the start. Because everyone is working toward the same goals, the process moves more efficiently and has fewer surprises along the way.
How the Design-Build Home Addition Process Works
Every home addition is unique, but the design-build process generally follows a similar path:
Initial consultation: The team meets with you to understand your goals, challenges, and vision for the new space. This includes discussing budget ranges, architectural style, and project feasibility.
Conceptual design: Designers create early sketches and layout options that fit your home and lifestyle. Because builders are involved at this stage, they can offer input on structural requirements, material costs, and potential challenges.
Budget development: You receive a realistic estimate based on the complexity of the design. This step eliminates guesswork and prevents expensive surprises that often come from traditional building models.
Revisions and final plans: The team refines the design until it meets your expectations. Plans are detailed enough for construction and for obtaining necessary permits.
Permitting and scheduling: Design-build teams handle all zoning and approvals, which is especially valuable in Ann Arbor’s historic neighborhoods.
Construction: Once construction begins, the team follows the agreed timeline and maintains open communication about daily progress. Because design and construction teams are aligned, the project stays consistent with the approved plans and selections.
Final walk-through: You review the completed addition with your project manager so every detail is finished to your expectations.
The full-service approach to home additions reduces delays, improves design accuracy, and produces a cohesive final result that integrates beautifully with the rest of your home.
Why Design Build is Ideal for Home Additions
A design-build home addition offers several advantages, especially for homeowners expanding older or historic homes in Ann Arbor.
Better Communication from Start to Finish
With a single team handling everything, communication is clearer and more focused. You don’t have to act as the go-between for architects and contractors. It reduces your stress and eliminates a lot of miscommunication.
More Accurate Budgeting
Because pricing is developed early with builder input, estimates reflect real construction conditions. Potential issues are identified before final plans are completed, which protects you from unexpected costs.
Faster Timelines and Workflow
Design and construction phases often overlap, which keeps projects moving forward. When adjustments are needed, the team can pivot quickly without waiting for outside approvals.
Better Consistency in Craftsmanship
A design-build team works with a single goal. Details like finishes and architectural features are determined at the start of the project. This works well for historic homes where additions need to blend into the existing structure of the home.
Easily Tailored to Work in Older or Historic Homes
Many homes in Ann Arbor were built decades ago. They need structural and mechanical updates, along with the addition. Design-build contractors understand how to bring homes up to current standards without taking away from their historic charm.
What Types of Additions Work Best With the Design-Build Process?
Design-build is flexible and works well with a wide variety of home addition projects, including:
No matter which type of addition you choose, the unified process of a design-build team can make the final space look and feel more cohesive with the rest of your home.

For many families, the idea of bringing aging parents closer to home is both a deeply personal and practical decision. Whether it’s about caregiving, emotional closeness, or simply better day-to-day convenience, adding an auxiliary dwelling unit to your property can be a powerful solution. As you explore auxiliary dwelling unit options, the debate that typically comes into focus is attached versus detached.
This isn’t just a design choice—it’s a lifestyle decision that affects how your family functions, how your property feels, and how well your space accommodates long-term needs.
In this article, we’ll distinguish the key differences between attached and detached ADUs and help you determine which option best supports your goals as you create space for your loved ones.
What Is an ADU—and Why Are More Families Choosing Them?
An auxiliary dwelling unit (ADU)—sometimes called a mother-in-law suite, casita, backyard cottage, or secondary suite—is a fully functional, self-contained living space built on the same residential lot as a single-family home. Typically including a bedroom, bathroom, kitchen or kitchenette, and living area, these additions can attach to the primary home or be completely detached, depending on your needs and property layout.
For families considering long-term housing solutions for elderly parents, ADUs offer a thoughtful middle ground. They provide the proximity that makes caregiving and connection easier while still giving parents a sense of autonomy and privacy.
In recent years, ADUs have gained traction for several reasons:
Multigenerational living is rising. According to Pew Research Center, nearly 60 million Americans now live in multigenerational households—a 400% rise since 1971.
Real estate costs are climbing. Adding space for family is typically a more economical decision than buying or renting an entirely separate home for an aging parent.
Aging in place is a growing priority. ADUs allow seniors to retain independence while staying close to family for support, a major step in late-stage quality of life.
Zoning strategies are evolving. Many cities are loosening restrictions to encourage ADU construction as a way to expand affordable housing options.
If you’re looking for a future-proof way to care for family, support aging in place, or even increase your property’s long-term value, adding an ADU could be one of the smartest—and kindest—real estate decisions you make.
An attached ADU is structurally connected to your existing home—either as a converted garage, basement suite, or newly built wing. Here’s when it makes the most sense:
When You Need Easy Access
If your parent or loved one needs frequent assistance or mobility support, attached ADUs offer immediate accessibility. You can check in often without stepping outside, and modifications like ramps, stair lifts, or grab bars are easier to integrate into your home’s existing layout.
When You Want to Save on Utilities
Because attached ADUs can share plumbing, electrical, and HVAC systems with the main house, you’ll often save on both construction and utility installation costs. This can be especially beneficial for homeowners working within a specific budget.
When Lot Size Is Limited
For smaller lots or homes in urban neighborhoods, zoning regulations may limit the footprint of detached structures. In cases like these, an attached ADU might be the most effective way to add extra living space.
Still, attached ADUs aren’t for everyone. The personal boundaries are typically blurrier, and some families may find it harder to maintain a healthy sense of independence. Even with a separate entrance, the shared walls can lead to noise issues or lack of privacy. The decision will ultimately depend on the needs and temperament of those involved.
Detached ADUs: Privacy, Independence, and Long-Term Value
A detached ADU is a stand-alone structure, often taking the form of a tiny house in your backyard. These are ideal for families who want their loved ones close—but not too close. Some families find the extra degree of separation, however minor, an important factor. Here are a few signs a detached dwelling is your best bet:
When Privacy Is a Top Priority
For parents who are still active and independent, a detached ADU provides a space that feels more separate. It allows them to continue their own routines, entertain their own guests, and maintain a sense of personal dignity without sacrificing the emotional connection or proximity to assistance when needed.
When You’re Thinking Long-Term
Detached ADUs offer a bit more flexibility for the future. If your family only needs a temporary place to stay, you may eventually want to use the space as a rental unit, home office, guesthouse, or studio. Detached structures also tend to command higher resale value, offering better return on investment if and when you decide to sell.
When You Want More Design Freedom
Because they don’t rely on your home’s existing layout or structure, detached units naturally offer more creative leeway in terms of design. This is especially helpful when planning for aging-in-place features like single-level living, extra-wide doorways, and step-free entries.
Here’s the trade-off: Detached ADUs typically cost more to build. You’ll likely need to run new utility lines, pour a separate foundation, and meet additional permitting requirements. But for many families, the long-term value—both financial and emotional—outweighs the initial investment.
Making the Right Choice For Your Family
Choosing between an attached and detached ADU will likely come down to how your family lives today—and how you want that to look five, ten, or even twenty years from now. Here are a few decision factors to consider:
Decision Factor
Attached ADUs
Detached ADUs
Caregiving needs
Easier proximity
Slightly less accessible
Cost efficiency
More affordable upfront
Higher cost, better long-term ROI
Privacy needs
Moderate
High
Future flexibility
Moderate
High
Design control
Limited by existing structure
Greater creative freedom
Size constraints
Limited by a compact lot
More outdoor space available
If your parent needs close support and you’re looking to build quickly and economically, an attached ADU may be your best route. If your top priorities are independence, flexibility, and long-term property value, a detached ADU is worth the extra investment.
Still undecided? The good news is that both options can be tailored to create beautiful, functional spaces that enhance your home and strengthen your family bond. The right design-build partner can help you make the decision that’s best for you.
