The Leading ADU Builder in Asheville, NC

Adding an accessory dwelling unit (ADU) is one of the smartest ways to expand the usefulness of your property without buying more land. Whether you're planning a guesthouse for family, an independent space for aging parents, or a short-term rental to bring in income, an ADU gives you options that grow with your needs. At Blueprint Builders, we help homeowners throughout Asheville design and build ADUs that match their property, meet code requirements, and make the most of the available space.

We've worked with clients across West Asheville, Kenilworth, and North Asheville who came to us for a separate, functional space without giving up privacy.

Why ADUs Make Sense in Asheville

Many local homeowners in Asheville are building small, second units on their existing lots because of the cost of land. Whether you're offsetting your mortgage with a long-term tenant or taking advantage of Asheville's tourism appeal with a short-term rental, an ADU adds real, tangible value.

And for families, ADUs or "granny flats" make it possible to keep aging parents nearby without sacrificing independence. Some of our clients have built them for college-aged children who need a private space during breaks. Others want a rental unit that allows them to host travelers visiting the Blue Ridge Parkway, Biltmore Estate, or downtown Asheville.

We Build Attached and Detached ADUs in Asheville

Attached ADUs

Attached ADUs are created by converting space within or connected to the main house. A basement apartment, finished garage, or side addition can all become fully functional living units. These tend to be more cost-effective since they often use existing roofing, foundation, and utility systems. Attached options are great for multigenerational living or when you want to keep utilities under one account.

In Asheville, some neighborhoods have restrictions on short-term rentals in attached units, so it's important to know how your intended use aligns with local rules. We help you explore what's allowed before you commit to a layout.

Detached ADUs

Detached ADUs are separate structures, often located behind or beside the main home. These standalone cottages or tiny homes offer more privacy and are often easier to rent to travelers or tenants. Because they require new foundations, utilities, and site prep, they typically cost more than attached options. That said, they also offer more long-term flexibility and often increase property value.

We've built detached ADUs that serve as art studios, backyard offices, guesthouses, and Airbnb rentals. If you're on a sloped lot in Montford or South Asheville, we can help with grading, access paths, and utility routing to make the build feasible.

Layout, Floor Plan, and Design Details

Smart Use of Space

ADUs in Asheville usually fall between 500 and 900 square feet. That's enough for a full kitchen, bathroom, bedroom, and living space, if the layout is done right. We work with clients to figure out the best way to use the square footage. Open-plan kitchens, stacked washer-dryer units, and built-in shelving help maximize every inch.

In some cases, we incorporate vaulted ceilings, large windows, or skylights to make the space feel larger. The finishes and layouts we choose will be influenced by the use of the space. A vacation rental unit would likely have different features than a unit for a long term tenant, for instance.

Tailoring the Design to Its Use

The best floor plan depends on who will live there. For a long-term tenant, you'll need a full kitchen and private sleeping area. For a weekend Airbnb, a studio-style layout with a kitchenette may be more than enough. If you're housing an aging relative, we'll recommend wider doorways, step-free entries, and low-maintenance surfaces.

We've built ADUs with private patios, loft sleeping areas, and storage lofts accessible by ladder. We've also converted detached garages into compact one-bedroom apartments with their own entry and utilities.

Building Costs, Materials, and What to Expect

Realistic Price Ranges

In Asheville, most ADUs cost between $160,000 and $280,000 to build, depending on size, type, and finishes. But do not take that range as an established fact -- there are so many factors involved that may push the cost down or up.

Attached conversions usually land at the lower end of that range. New, detached builds with full kitchens, upgraded flooring, and custom tile work can run higher. Site challenges like steep grades or limited access may also increase excavation and foundation costs.

We walk through these numbers in detail during the planning phase. You'll see how your choices (from siding materials to appliance brands) affect the overall budget. For example, choosing standard LVP flooring and stock cabinets can save thousands compared to hardwood and custom millwork.

Material Choices That Work in Asheville

Because of our seasonal humidity and temperature swings, we recommend materials that hold up to the local climate. That might include fiber cement siding, waterproof luxury vinyl plank, and dual-pane windows with good energy performance. We also suggest energy-efficient appliances and mini-split HVAC systems for heating and cooling small spaces efficiently.

These choices will keep your long-term costs down. Whether the unit is for your family or a renter, a well-built, efficient space makes ownership easier.

Permitting and Zoning in Asheville

Asheville has become more ADU-friendly over the years, but zoning still varies by neighborhood and property type. Some areas allow short-term rentals in detached units, while others limit rentals to 30 days or longer. Minimum lot sizes, setbacks, height limits, and parking rules also come into play.

We help navigate that process by handling site plan approvals, building permits, and coordination with local agencies. If your property is on city sewer, we check capacity limits. If you're on septic, we coordinate with Buncombe County to determine whether expansion is possible. That level of planning helps you avoid surprises and keeps the project moving.

Building a Backyard Rental or Guest Unit in Asheville

Asheville's popularity as a tourist destination makes detached ADUs a smart investment for some homeowners. Proximity to downtown, the River Arts District, and popular spots like the North Carolina Arboretum adds short-term rental appeal. We've helped clients turn unused backyard space into clean, modern units that book out every weekend.

At the same time, many families want something quieter, like a place for relatives to stay over the holidays or a future home for an adult child. Whatever your goal, we help make sure the layout, finishes, and design match how the space will be used.
