Local ADU Builder in Fletcher, NC

Building an accessory dwelling unit, or ADU, is one of the most practical ways to add living space to your property. Whether you're planning for a parent who needs to live nearby, a long-term guest space, or a rental that brings in steady income, an ADU can give you flexibility without the cost of buying another property. At Blueprint Builders, we help homeowners in Fletcher design and build ADUs that fit their lot, meet local requirements, and work well for real-life needs.

Why People Are Building ADUs in Fletcher

Some homeowners want to keep their family close without everyone sharing the same kitchen. Others want to build a small rental unit to offset the mortgage or create a space for adult children who haven't left the nest yet. We've even worked with clients who wanted a quiet home office or art studio separate from the main house. What all of these projects have in common is a desire to use existing property in a smarter way.

We've seen a growing interest in ADUs across Fletcher and nearby towns like Arden and Mills River. Zoning is starting to evolve, and more lots are being approved for detached and attached secondary structures. It's still important to check site-specific rules, especially regarding minimum lot size, utility access, and whether the unit can be rented.

Attached vs. Detached ADUs

Attached ADUs

An attached ADU shares at least one wall with the main home. These are often built by converting a basement, garage, or unfinished wing into a private suite. This option works well when you want close proximity but still want to create some level of separation. It also tends to be more budget-friendly because it uses existing foundation and roofing systems.

Attached ADUs are popular among homeowners who want to age in place or who are bringing in a parent or in-law. It's easier to manage utilities, and you don't always need to run new sewer lines or electrical panels if the existing ones can handle the additional load.

Detached ADUs

Detached units are fully separate structures with their own foundation, roof, and entryway. Think of a small cottage in the backyard or a standalone one-bedroom unit with a kitchenette and bathroom. These are more expensive than attached options, but they offer more privacy and are often easier to rent.

Detached ADUs require more planning when it comes to site prep, zoning setbacks, and utility routing. We help homeowners figure out how to make it work on their property, including grading, access paths, and whether you'll need to upgrade the main home's utility services.

Planning the Layout and Use

Floor Plan and Size Considerations

Most ADUs range between 400 and 1,000 square feet. That might sound small, but with the right layout, it's enough for a full kitchen, a living area, a bedroom, and a bathroom. We help clients make smart use of every square foot. That could mean combining the laundry area with the bathroom, using built-ins for storage, or including vaulted ceilings to make the unit feel larger.

The floor plan depends on how you plan to use the space. If it's for short-term guests, you might skip a full kitchen in favor of a wet bar and microwave setup. If it's for long-term renters, you'll want a standard kitchen, a private bedroom, and a separate entrance.

Use Cases That Shape the Design

For aging parents, we focus on step-free entries, wider doorways, and easy-to-use fixtures. For renters, we think about durability, soundproofing, and privacy. If the unit is for an adult child who may only be there a few years, we might design it with future resale in mind. These details make a difference when it comes to daily use, maintenance, and how the ADU fits into your long-term goals.

Costs, Materials, and Permitting

What ADUs Typically Cost in This Area

Most ADUs in the Fletcher area fall between $130,000 and $250,000, depending on whether they're attached or detached and what features are included. Site conditions and utility access have a major impact. For example, building on a slope or needing a new septic system can add significant cost. The choice of finishes also matters. LVP flooring and stock cabinets will keep the budget lower than tile, stone counters, and custom built-ins.

We help clients understand where the budget is going and how to make adjustments without sacrificing the overall quality or function of the space.

Navigating Permitting and Zoning in Fletcher

Fletcher has specific guidelines for accessory structures. We stay up to date on current regulations around setbacks, height restrictions, and whether you can legally rent the unit. Permitting often includes architectural review, site plan approval, and inspections. We manage that entire process, including communication with the building department, to keep things moving forward.

Some projects may also require coordination with utility companies or health departments, especially if you're adding a separate water meter or expanding an existing septic system. These are all things we handle on your behalf.
