Mississippi Pool Fence Requirements at a Glance
State and local laws change. This information reflects our best research as of September 2026, but you must confirm current requirements with your local building department before installing or modifying any pool barrier. Mississippi counties and cities may adopt codes stricter than the state code (Miss. Code 17-2-4).

Mississippi Pool Barrier Law
Mississippi has two separate rules, and which one reaches your pool depends on where it is and who owns it.
The state construction code. Since 2014, state law has required each county and city to adopt, as its minimum code for homes, one of the last three editions of the International Residential Code (IRC) adopted by the Mississippi Building Codes Council (Miss. Code 17-2-4). Counties and cities could opt out by resolution within 120 days, and the state set that deadline at November 30, 2014 (Mississippi Insurance Department). The window has closed, so no county or city can opt out now. Some did in 2014, and those gaps are permanent: no state code stands behind them. Confirm with your county or city whether a code applies to your address. Counties and cities may also adopt stricter codes.
Which IRC edition carries the pool rule. Whether an adopting county or city has a barrier rule at all depends on the edition it uses. In the 2015, 2018 and 2021 IRC, Section R326 in the main chapters sends pools to the International Swimming Pool and Spa Code (ISPSC), whose Section 305 is the barrier rule; the 2024 IRC moves it to Section R328. In the 2012 IRC, the barrier rule is only in Appendix G, and an appendix applies only if it is adopted by name (Miss. Code 17-2-3). Local adoptions can narrow the pool section too: the City of Petal, for example, applies R326 only if the city separately adopts the ISPSC. Ask your building department which edition it enforces and whether its code includes the pool rules.
Where a county or city's code includes the ISPSC, Section 305 applies: at least 48 inches of height outside, openings too small for a 4-inch sphere, self-closing and self-latching gates, and alarms or another listed option where the house wall forms part of the barrier (ICC model text, 2024 edition).
The William Lee Montjoy Pool Safety Act. A separate state law, Mississippi Code Chapter 45-43, sets pool yard enclosure rules only for pools owned, controlled or maintained by the owner of a multiunit rental complex or by a property owners association (House Bill 1281, 2012). It does not cover a pool at an owner-occupied single-family home. For covered pools it requires:
- An enclosure at least 48 inches high, measured on the side away from the pool, with no gap under it that a 4-inch sphere can pass (Miss. Code 45-43-7)
- Where horizontal rails are 45 inches or more apart, no opening a 4-inch sphere can pass; where they are closer, openings no wider than 1 3/4 inches
- No chain-link in a new enclosure built after July 1, 2012, and no diagonal members lower than 49 inches
- Decorative cutouts no wider than 1 3/4 inches
- A building wall as part of the enclosure only if its doors and windows meet the Act's rules
- Gates that close and latch by themselves, open outward and can be locked, with the latch at least 60 inches above the ground. A lower latch must be on the pool side only, at least 3 inches below the top, with no opening over 1/2 inch within 18 inches of it; a gate that opens only by key, card or combination on both sides may have its latch at 42 inches or higher (Miss. Code 45-43-9)
City & County Variations in Mississippi
Which rule reaches your pool depends on whether your county or city adopted the state code or opted out in 2014. We have not verified individual cities' pool rules; ask your building department.
| Where | What applies |
|---|---|
| Counties and cities that did not opt out | Must adopt one of the last three Council-adopted IRC editions as a minimum, and may adopt stricter codes (Miss. Code 17-2-4). |
| Counties and cities that opted out in 2014 | No state code applies. If one adopts codes later, the Council's codes are the minimum (Miss. Code 17-2-5). |
| Rental complexes and HOA pools, anywhere | The Montjoy Pool Safety Act applies statewide (Miss. Code 45-43). |
Above-Ground Pools in Mississippi
For an above-ground pool, the ISPSC lets the wall act as the barrier if it rests on grade and measures 48 inches or more around its full perimeter; the ladder or steps must be removable, lockable or enclosed. Whether that applies to you depends on your county or city's code.
