Swimming pool rules in Sierra Madre, California
Allowed with a permit
Yes, with a building permit. In Sierra Madre's R-1 zone a pool, spa or hot tub (including its equipment) must be at least 5 feet from side and rear property lines. If it's within 25 feet of a street and visible from it you need a conditional use permit, unless a 6-foot solid fence or wall hides it from the street; a pool more than 25 feet away but still visible needs a minor conditional use permit.
| Setback from side and rear lines | 5 feet [1] |
| Within 25 ft of a street and visible | Conditional use permit [2] |
| Near a street, screened | Allowed with 6-ft solid fence/wall, 5 ft from the line, not visible [3] |
| More than 25 ft from street but visible | Minor conditional use permit [4] |
| Building permit | Required to install, alter or repair a pool, spa or hot tub [5] |
| Starting work without a permit | Double permit fee [6] |
| Hillside (R-H) zone | Administrative hillside development permit [8] |
Zoning setbacks (R-1)
Section 17.20.065 covers swimming pools, hot tubs, spas, pool and spa equipment and similar facilities. The basic setback is 5 feet from the side and rear property lines [1]. Location relative to the street is the main issue:
- Within 25 feet of a street or alley and visible from it: needs a conditional use permit under Chapter 17.60 [2].
- Screened by a 6-foot solid fence or wall: allowed without a use permit if the pool is at least 5 feet from the property line and can't be seen from the street or alley [3]. On sloping ground the wall can vary up to 8 inches above or below 6 feet.
- More than 25 feet from the street but visible from it: needs a minor conditional use permit from the director [4].
Building permit
Every applicant for a permit to install, alter or repair a pool, spa or hot tub must describe the work in writing and pay the fee set by City Council resolution [5]. Starting pool work without a required permit means paying double the permit fee [6]. Plans must show compliance with the adopted pool code before final inspection; the City's Title 15 still names the 1991 Uniform Swimming Pool, Spa and Hot Tub Code [7], which is an old edition, so expect Building and Safety to apply current state codes as well.
Fences and safety barriers
The local sources we reviewed don't set pool barrier details. State law requires at least two drowning-prevention features for a new pool at a home (see state rules).
Hillside zone
On R-H lots, pools, hot tubs and spas need an administrative hillside development permit [8]; one within 25 feet of a street or alley and visible from it needs a full hillside development permit instead [10].
Maintenance
Owners must keep a pool filtered and treated so the water stays clear and circulating, or fully drained and dry [9]. An unmaintained pool is a public nuisance the City can abate.

Next steps
- Site the pool and equipment at least 5 feet from side and rear lines, and decide whether it will be within 25 feet of or visible from a street.
- If it will be visible from a street, apply to Planning & Community Preservation for a conditional use permit or minor conditional use permit, or plan a 6-foot solid screening wall.
- Submit pool plans to Building and Safety (232 W. Sierra Madre Blvd., (626) 355-7138) for a building permit before starting work, including the drowning-prevention features required by state law.
- On an R-H zoned lot, also apply for an administrative hillside development permit.

California state rules for swimming pools
Pools need a city or county building permit, and local zoning sets setbacks. The state's Swimming Pool Safety Act (Health & Safety Code §115920 et seq.) adds safety rules:
- Drowning prevention features: when a building permit is issued for a new pool or spa, or to remodel one, at a private single-family home, it must have at least two of seven safety features (§115922):
- an enclosure that isolates the pool from the house
- removable mesh fencing (ASTM F2286) with a self-closing, self-latching gate
- a safety pool cover (ASTM F1346-23)
- exit alarms on doors and windows that open directly to the pool
- self-closing, self-latching devices on those doors, released at least 54 inches up
- a pool alarm (ASTM F2208; child-worn alarms don't count)
- other equally protective, independently verified means
- Some pairs don't count, such as a safety cover plus a pool alarm. The building official inspects before final approval.
- Enclosure standards (§115923): at least 60 inches high, no more than 2 inches of clearance at the bottom, gaps that won't pass a 4-inch sphere, no handholds or footholds, and gates that open away from the pool with self-latches at least 60 inches up.
- What counts as a pool: any structure with water over 18 inches deep, including above-ground pools, hot tubs and spas (§115921). Spas with a locking ASTM F1346 cover, apartment complexes and public pools are exempt (§115925).
- Small pools: the 2025 Residential Code exempts prefabricated pools under 24 inches deep from a building permit.
