Zoning Variances

Hamilton County provides applications for:
- Development Standards Variances
- Use Variances
- Special Uses
These requests may require review by the Hamilton County Board of Zoning Appeals.

Approval is not automatic, so don’t begin a project assuming a variance will be granted.
Building Permits & Zoning
Zoning approval and a building permit are related but aren’t necessarily the same thing.
A project may need to satisfy zoning requirements before a building permit can be issued.
HOA Rules
If your property is in a homeowners association, HOA restrictions may apply in addition to local zoning laws.
An HOA may have additional rules for:
- Fences
- Sheds
- Pools
- Home businesses
- Parking
- Exterior improvements
- Signs
Government approval doesn’t override private HOA restrictions.
