Metro Nashville's Pool Barrier Rules and Permits
Metro Nashville writes its own building rules. State law (T.C.A. 68-120-101) lets a local government that adopts and enforces its own codes run them in place of the state fire marshal's standards. Its residential pool permitting instructions say the barrier rules are in the International Swimming Pool and Spa Code (ISPSC), linking to the 2018 edition, Section 305, and point to Chapter 16 of the Metro Code for the residential building code. ISPSC Section 305 requires:
- 48 inches of height or more on the outside of the barrier, for any pool deep enough to hold over 24 inches of water
- Gaps too small for a 4-inch ball, with the bottom edge no more than 2 inches off the ground
- Gates that swing out from the pool and shut and latch by themselves; a latch release lower than 54 inches goes on the pool side of the gate, at least 3 inches below the top
- Horizontal members on the pool side where they are less than 45 inches apart
- A 36-inch clear zone outside the barrier, free of equipment a child could climb
Four Nashville-specific points from Metro Codes. A property owner who lives in, or will live in, the single-family home may get the pool permit, with notarized affidavits; if the home is owned by an LLC or trust, or is a rental, a self-permit covers only work under $25,000. Registered contractors apply through ePermits. The application needs a site plan showing the pool and equipment with distances to property lines and easements, and a receipt for a pool alarm, which state law requires under Katie Beth’s Law. Call Tennessee 811 at least three working days before digging. And if the lot is in a Neighborhood Conservation or Historic Preservation overlay, Metro Codes sends you to the Historic Commission about its rules.

Frequently Asked Questions
Nashville Pool Fencing: Metro Codes, the ISPSC and a Pool Alarm
Nashville's pool rules run through Metro Codes. The barrier follows the International Swimming Pool and Spa Code: 48 inches, no 4-inch openings, self-closing and self-latching gates. The permit application wants a site plan and a pool alarm receipt, because Tennessee requires an alarm on most new pools.
Homeowners have more room here than many assume. An owner-occupant can pull the permit for a single-family home, so this does not have to be a contractor-only project, though LLC, trust and rental properties are capped at $25,000 of self-permitted work.
Suburbs outside Davidson County run their own codes, so confirm the rules with the city where the pool will be, and call Tennessee 811 before anyone digs.
