Before you apply
- Call the City of Hendersonville Planning Department: (615) 822-1000
- Search the municipal code for the chapter that covers your zoning district and proposed use.
- Use the local zoning map to look up your parcel's zoning designation before applying for a permit.
- Check FEMA flood zone for your parcel — flood-zone status changes setbacks, foundation requirements, and insurance.
- Check your HOA CC&Rs and recorded deed restrictions — they are common in Hendersonville and frequently restrict ADUs, fences, and exterior changes beyond what zoning allows.
Key Zoning Facts
Hendersonville regulates land use through its current Zoning Ordinance. Because district standards and accessory-use rules have been updated, parcel-specific design should start with the current zoning map and ordinance rather than older generic R-10/R-15 summaries.
Accessory Apartments and Detached Accessory Dwellings
The current Zoning Ordinance distinguishes between an accessory apartment within or attached to the principal dwelling and a detached accessory dwelling.
For an attached/internal accessory apartment, the ordinance limits the apartment's heated area to 40% of the combined heated area of the principal dwelling and apartment and includes additional design requirements.
Detached accessory dwellings have a different approval path. Under the current ordinance:
- they are not permitted on lots of 29,999 sq ft or smaller;
- they must be located behind the rear plane of the principal dwelling;
- they require a conditional use permit;
- the current rule requires 20 ft from side and rear property lines;
- other district, design, building-code, utility, and site requirements still apply.
These rules replace the previous page statement that Hendersonville ADU regulations were simply “not confirmed.”
Development Process
- Confirm the parcel's current zoning district.
- Determine whether the proposal is an attached/internal accessory apartment or a detached accessory dwelling.
- Review the specific use standards and the underlying district dimensions.
- Obtain any required conditional-use or other zoning approval.
- Apply for building permits and complete inspections.
