If you're listing a single-family home in Raleigh, Charlotte, Greensboro, or any other North Carolina city with more than fifty thousand residents, your seller may now have a legal right to add a second, income-producing home to that same lot. That's not a hypothetical. It's the result of Senate Bill 445, the Regulatory Reform Act of 2026, which Governor Josh Stein signed into law on August 11, 2026.
What actually changed
The bill requires local governments in non-coastal cities with fifty thousand or more residents to allow at least one accessory dwelling unit, commonly called an ADU, on eligible single-family lots. According to NC REALTORS' legislative summary, local governments in those cities can no longer:
- Require a conditional zoning district just to add an ADU
- Set minimum parking requirements or other parking restrictions tied to the ADU
- Block long-term rental of the primary home or the ADU to separate households
- Refuse a utility connection when the existing system has capacity to serve both dwellings
- Charge permitting fees higher than what a comparable single-family home would pay
- Cap the ADU below eight hundred square feet or require it to be larger than a thousand
Local governments still retain some control. They can require a setback of ten feet or whatever the standard setback is for that zoning classification, they can require the ADU to sit to the side or rear of the primary home, and they can require it to be smaller than the primary residence.
There are real limits on the scope too. The law doesn't override a private HOA covenant that restricts dwelling types, it doesn't apply inside historic preservation districts or on National Historic Landmark properties, and it doesn't apply to an ADU that isn't connected to water and sewer, or well and septic.
Why this belongs in your next listing conversation
This isn't a market prediction or a builder story. It's a fiduciary conversation you may now need to have with almost every seller of a qualifying single-family home in a mid-size or larger North Carolina city. A seller sitting on an underused garage or a large backyard may be looking at real added value they didn't know was legally available to them. A buyer evaluating a property for multigenerational living, a rental income stream, or space for aging parents needs to know whether that lot actually qualifies before they write an offer.
The brokers who get ahead of this will be the ones who can walk a client through the specifics accurately: what the city can and can't require, what an HOA might still block, and what the size and utility rules actually are. Getting even one of those details wrong isn't a small mistake. It's the kind of gap that turns into a disclosure problem or a client who feels let down after the fact.
Key Takeaways
SB 445 requires non-coastal NC cities with 50,000+ residents to allow at least one ADU on eligible single-family lots
Local governments can't impose minimum parking requirements, block long-term rentals, or cap ADUs below 800 square feet
HOA covenants, historic districts, and National Historic Landmarks are excluded from the law
This is a live conversation to have with sellers about added value and buyers about property flexibility, not a future trend to watch
Frequently Asked Questions
- Does this apply to every city in North Carolina?
Based on the bill text, it applies specifically to non-coastal local governments with a population of fifty thousand or greater. Smaller towns and coastal jurisdictions aren't covered by this particular mandate. - Can my client's HOA still say no to an ADU?
As we read the law, yes. It explicitly does not override private covenants or contractual agreements between property owners, so an HOA restriction on dwelling types would still apply. - Does the lot need public water and sewer?
The law does require a utility connection of some kind, whether that's public water and sewer or a well and septic system. A lot with no service connection at all wouldn't qualify under these provisions. - Is this in effect right now?
The bill was signed on August 11, 2026. For the specific effective date tied to the ADU provisions, the full bill text on the General Assembly's site is the source to check before advising a client on timing.
