Permit briefing
Do you need a permit for a pool?
Only a prefabricated pool less than 24 in deep is exempt under the International Residential Code; any other pool needs a permit and a barrier.
The reliable short answer
Decide whether the pool is permanent or storable and how deep it gets, then plan the barrier before the hole: the enclosure is part of the approval, not an accessory.

The model code’s answer
Does a pool need a permit?
Almost every pool does. The International Residential Code exempts one kind: a prefabricated pool less than 24 inches deep. Its companion pool code then asks for a barrier around an outdoor pool or spa at least 48 inches high, with no more than 2 inches under it on grass or gravel, unless a safety cover meeting ASTM F1346, a powered one for a pool, takes its place.
| Rule | What it exempts |
|---|---|
| Model code (IRC R105.2) | Prefabricated and under 24 in deep |
| Austin | Prefabricated under 24 in, or any storable pool |
| Los Angeles | Up to 24 in deep and 250 sq ft of water surface |
Austin goes further than the model: it exempts whatever the pool code's residential chapter leaves out, which is any pool made for above-ground use that comes apart for storage, and it files the rest as small projects. Los Angeles caps its exemption by surface as well as depth, and California's law adds its own layer: a permitted pool at a single-family home needs 2 of 7 drowning-prevention features, and an enclosure among them has to stand 60 inches high.
A three-step permit decision
1. Permanent or storable
The model pool code's residential chapter governs permanent pools, including ones partly or wholly above grade, and leaves out pools made for above-ground use that come apart for storage. Austin exempts exactly those; the model code and Los Angeles go by depth, and Los Angeles by surface too.
2. Plan the barrier with the pool
The pool code asks for a barrier at least 48 inches high with no more than 2 inches under it on grass or gravel, and 4-foot construction fencing from the first excavation until it stands. Where a house wall forms part of it, the doors and windows that open to the pool need alarms.
3. Count the safety features in California
A permitted pool at a California single-family home needs 2 of 7 drowning-prevention features, inspected before final approval. Some pairs do not count: an exit alarm and a self-closing device on the same door, or a safety cover with a pool alarm.
What Austin and Los Angeles say about a pool
Austin
- No permit
- A prefabricated pool less than 24 inches deep, and any pool made for above-ground use that can be taken apart and stored: the pool code's chapter on residential pools leaves those out, and Austin exempts whatever that chapter does not cover.
- Permit
- Any other pool, in the ground or permanently above it, is filed on the Pool/Uncovered Deck form as a small project and billed at the small-projects review rate.
- Fees
- Small projects plan review$146.15
Los Angeles
- No permit
- A pool no deeper than 24 inches with no more than 250 square feet of water surface.
- Permit
- Anything bigger needs a building permit, and California then requires at least two of seven drowning-prevention features at a single-family home, from an enclosure at least 60 inches high to a safety cover or exit alarms, checked before final approval.
- Fees
- LADBS works out the permit fee from the pool's valuation.
