Frequently Asked Questions
Can I build an ADU in Charlotte?
Yes. North Carolina House Bill 488 (effective October 1, 2023) requires Charlotte to allow ADUs by-right on all residential lots. You can build a detached or attached ADU up to 1,200 sqft. No owner-occupancy requirement applies. Charlotte's Unified Development Ordinance (2023) incorporates these ADU allowances. Permits are processed ministerially through Charlotte Development Services.
What does North Carolina HB 488 require for ADUs in Charlotte?
NC HB 488 (2023) requires municipalities with over 10,000 population (including Charlotte) to allow ADUs by-right on all residential lots. Key protections: municipalities cannot require more than 1 parking space per ADU, cannot require owner-occupancy, and must approve code-compliant ADU applications ministerially (no discretionary review or hearings). Charlotte's UDO reflects these requirements.
Does Charlotte require a permit for short-term rentals?

What is Charlotte's new Unified Development Ordinance (UDO)?
Charlotte adopted a new Unified Development Ordinance (UDO) effective June 1, 2023, replacing the legacy zoning ordinance. The UDO uses a place-type based framework with Neighborhood districts (N1 through N4), Commercial Corridor districts, Transit-Oriented Development zones near light rail stations, and Mixed-Use districts. The UDO streamlines zoning categories and implements NC HB 488 ADU requirements.
Are solar panels required on new homes in Charlotte?

However, Duke Energy (the primary utility serving Charlotte) offers net metering programs for homeowners who install solar.
