Swimming pool rules in Newport Beach, California
Pools and spas are allowed but must have safety fencing, and one placed at existing grade and under 42 inches tall can sit in a front, side or rear setback (not one along an alley). Pool fencing in a front setback may exceed the normal 42-inch fence limit if it is at least 40% open or glass. We couldn't review the city's building code (Title 15), so the building-permit requirement here comes from state rules, which require a permit and at least two drowning-prevention features for a new home pool.
| Safety fencing | Required for pools, spas and similar features [1] |
| Pools/spas in setbacks | Allowed if at existing grade and under 42 inches tall; not in setbacks abutting an alley [3] |
| Pool fence in front setback | May exceed 42 inches if at least 40% open (or glass/Plexiglas), only as tall as needed for safety [2] |
| Bluff, canyon and shoreline lots | Pools need leak-prevention design (e.g., double walls with subdrains and leak detection) [4] |
Fencing
Newport Beach's coastal zone code (Title 21) requires swimming pools, spas and similar features to provide safety fencing [1]. The 2010 version of the inland zoning code (Title 20) says pools must be fenced in compliance with Municipal Code Title 15, the city's building code [5], which we didn't review; it sets the actual barrier standard along with the state Swimming Pool Safety Act.
Front-yard fences are normally capped at 42 inches. Pool, spa and pond fencing in a front setback, or in a side or rear setback regulated like a front setback on a 42-inch lot, may be taller if it is built of open grillwork, wrought iron, lattice or pickets so that at least 40% is open, or of glass or Plexiglas, and is no taller than the minimum needed for safety [2].
Where the pool can go
Pools, spas and similar equipment placed directly on existing grade and less than 42 inches tall may be located in a required front, side or rear setback, except a setback abutting an alley [3]. Raised pools or decks taller than that must stay out of required setbacks unless another encroachment applies (for example, decks and patios up to 18 inches high may go in side and rear setbacks). On waterfront lots, anything in a setback next to the bay, ocean or channels is limited to 42 inches above existing grade.
Bluffs, canyons and shoreline lots
On lots on coastal bluffs, in canyons or in identified shoreline areas, pools must be designed to minimize or avoid leaks, such as double-wall construction with subdrains and leak detection devices [4]. A pool doesn't count as an "existing structure" that a seawall or other shoreline protective device can be built to protect.
Notes on our sources
We don't have the city's building code (Title 15) or current Title 20, and the Title 20 copy we have dates from 2010. A building permit and plan check through the Building Division should be expected; confirm the current barrier rules there.

Next steps
- Ask the Planning Division whether your lot is in the coastal zone and which setbacks apply, especially on alley, waterfront, bluff or canyon lots.
- Plan the pool barrier to meet the city's Title 15 building code and the state pool safety rules (at least two drowning-prevention features for a new home pool).
- Submit pool plans to the Building Division for plan check and a building permit; include the fence or barrier design.
- On bluff, canyon or shoreline lots, include the leak-prevention design (double wall, subdrain, leak detection) in your coastal development permit application.

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.
