Tennessee Building Permits
Building permits in Tennessee are issued by cities and counties, not the state, so the rules depend on where your home is. These are the Tennessee city we cover: Nashville.

Nashville Building Permits
4 project guides · 1,589 permits in 12 months · Metro Nashville Department of Codes and Building Safety
In Nashville, residential permits are issued by the Metro Nashville Department of Codes and Building Safety. Our counts use the city's Metro Nashville Building Permits Issued dataset. Short answers for each project we cover:
- Roof replacement: Usually yes. Nashville requires a building permit to install roofing, or to replace more than one-third of the roof. Repairs to an existing roof up to 33% of the roof area count as normal maintenance.
- AC or furnace replacement: Yes. New and replacement air-conditioning units, condenser replacements and furnaces changing size or fuel need a gas/mechanical permit in Nashville. Repairs to a furnace or condenser do not.
- New fence: Usually no. A new residential fence does not need a building permit in Nashville, but it must comply with the zoning code. Fences in historic districts need approval from the Historical Commission.
- New deck or porch: Yes. Building a new deck or replacing a deck requires a permit in Nashville, as does replacing more than 100 sq ft of deck boards or any footings or framing. Removing a deck without replacing it does not.

Not yet covered for Nashville: solar panel installation. We only publish a project guide when the city's open data identifies that work clearly enough to count at least 10 permits in 12 months and we have checked the rule against an official city source. Until then, ask the Metro Nashville Department of Codes and Building Safety directly before starting one of these projects.
How to Use These Tennessee Guides
Start with the city that issues permits for your address. If you live outside city limits, your county or township usually handles permits instead, and its rules can differ from the city pages here. Each project guide quotes the official rule, lists any fee the city publishes, and links to the source so you can confirm it before you start work. Permit counts show how often each kind of job is permitted locally, and median days to issue show how long a typical application took over the last 12 months. Rules and fees change, so treat the official source as final and call the permit office if your project is unusual.
