What Is an ADU?

An ADU, or Accessible Dwelling Unit, is a small, self-contained home built on the same property as your main house. It can be attached, detached, or even a converted space—like a finished garage or basement. These units include everything needed for comfortable living: a kitchen, bathroom, bedroom, and living area.

ADUs are becoming increasingly popular in Wake County because they offer flexibility and function for families who need extra space without the stress of moving.

Why Build an ADU?

by Riverbirch

There are many reasons homeowners are choosing to add ADUs, including:

  • Aging Parents or Family Members – Provide a safe, nearby home for loved ones while maintaining privacy and independence.

  • Extra Income – Rent your ADU to long-term tenants or use it as a short-term rental for an added source of revenue.

  • Guest Space – Give visitors their own private suite with all the comforts of home.

  • Future Flexibility – Use the space for adult children, a home office, or even as a future downsizing option for yourself.

Customized ADU Design for Your Family’s Needs

Every family is different—and your ADU should reflect that. Riverbirch Remodeling’s design-build approach ensures that your new unit is as functional as it is beautiful.

We’ll work with you to design a layout that fits your space, style, and accessibility needs. Want wide doorways and zero-step entries for aging-in-place comfort? Or perhaps extra storage, energy-efficient appliances, or soundproofing for privacy? We’ll make it happen.

Because we handle both the design and construction under one roof, communication stays simple, and your project moves smoothly from concept to completion.

ADU Requirements in Wake County

Wake County, along with cities like Raleigh, Cary, and Apex, allows homeowners to build ADUs on certain residential properties—but there are a few requirements to keep in mind:

  • Zoning Approval: Your property must be zoned to allow an ADU.

  • Lot Size: Many areas require a minimum lot size for detached units.

  • Size Limitations: The ADU’s square footage is typically limited to a percentage of the main home’s size.

  • Parking & Access: You may need to include an additional parking space and ensure safe access.

  • Permitting: All ADUs must meet building codes and receive the proper permits.

Don’t worry—Riverbirch Remodeling is familiar with the local codes and will guide you through the entire permitting and approval process.

We are very happy with the level of detail and craftsmanship. We will definitely be calling Chip for any future renovations.

Vera M.
“Riverbirch did an amazing job with our attic space from the start of the project to the last finishing detail. The team was professional, organized and on time…”
Jack P. , Google

Chip’s integrity and honesty were admirable traits, especially in a contractor. Bottom line, he delivered what he said he would deliver and kept us apprised along the way. The ultimate compliment, I believe, is that we would use him again.

George P.
My close friends who have remodeled their homes, all complained of bad contractors. I did not experience any of what they described. I’m amazed at how well my project went.

The Riverbirch Difference

4 Steps To Our Design & Build Method

Step 1

All remodels start with a consultation to discuss your family’s needs. We’ll review your needs, ideas, and vision for the room. Do you have a board on Pinterest? Send us a link after a consultation.

Accordingly, our in-house designer will make recommendations and plan the extent of your design. Talking through your remodel will help both you and Riverbirch join ideas and realistic solutions to any potential design issues. Every design and remodel are unique as is every client.

Step 2

Next, we move on to the design phase, which includes several steps that will guide us in creating a remodeling proposal. This proposal will feature 3D renderings to give you a clear visual of what your kitchen will look like. Once the proposal is presented and accepted, we move to the preconstruction phase.

Do you have a completed design? No problem! We would be happy to budget out any completed design. Additionally, we can assist you in obtaining bids for finish products and specialty trades. Depending on your design, we may also suggest enhancements. Whatever your needs, we are flexible and ready to adapt.

Step 3

During the preconstruction phase, a lot goes on. All finishing products are ordered and their delivery is arranged to ensure everything will be on hand in advance of when it is needed.

At this time we acquire any needed building permits. Your personal belongings will need to be packed and safely stored. There may be some site prep that will be done at this time.

Step 4

Finally, get to the build phase. We are very careful to take steps to protect the areas that will not be renovated because we respect your home. Riverbirch also takes onsite safety very seriously.

Daily communication is vital between the homeowner and any tradespeople to review plans and stay on all our targets. Throughout your project, we will closely supervise from start to finish.
