Swimming pool rules in Santa Barbara, California

Santa Barbara, Santa Barbara County · Ordinances checked 2026-10-05 · Reviewed · 7 cited sections

Allowed with a permit

Yes, with a building permit. Santa Barbara lets an in-ground pool or spa sit as close as 15 feet from the front lot line and 5 feet from side and rear lot lines (or outside the zone's setbacks, whichever is less), and every pool must be fenced to Building Code and state standards. Only prefabricated pools under 24 inches deep skip the permit.

What counts as a poolAny constructed body of water at least 18 inches deep, incl. spas and fishponds [1]
In-ground pool setbackZone setbacks, or 15 ft from front lot line and 5 ft from interior lot lines, whichever is less [2]

Above-grade pools and hot tubsTreated as open yard amenities [7]

What the rules cover

Section 30.140.210 of the inland zoning code (Title 30, as amended effective May 28, 2026) applies to any constructed body of water at least 18 inches deep that is accessory to a home. That includes pools, spas, whirlpools, fountains and fishponds [1].

Where an in-ground pool can go

The outside wall of the water-holding part of an in-ground pool or spa must be outside the zone's required setbacks, or at least 15 ft from the front lot line and 5 ft from all interior (side and rear) lot lines, whichever is less [2]. Because the RS zones' front setbacks are 15 to 35 ft, this lets a below-grade pool sit closer to the street than the house can.

Above-ground features and hot tubs

Fountains, waterfalls, slides and other above-ground water features can be no taller than 8 ft and must meet zone setbacks; Design Review may allow variation [6]. The definitions list hot tubs and above-grade pools and spas as open yard amenities [7]. The city's encroachment table (Table 30.140.090.C) does not allow residential open yard amenities in front or interior setbacks, so keep an above-ground pool or hot tub out of the setbacks. Pool filters and heaters follow the mechanical-equipment rules in §30.140.130.

Fencing

All pools must be fenced as the Building Code and state law require [3]. The city's 2025 code amendments require private pools to be built to California Building Code §3109 [4], which brings in the state Swimming Pool Safety Act's barrier and drowning-prevention features.

Permits

A building permit is required for a pool or spa. The only exemption is for prefabricated pools under 24 inches deep [5]. These are inland (Title 30) rules; Coastal Zone properties follow Title 28, which we didn't have, and may also need a coastal development permit.

  4. Schedule the barrier inspection before final approval and filling the pool.

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):
    1. an enclosure that isolates the pool from the house
    2. removable mesh fencing (ASTM F2286) with a self-closing, self-latching gate
    3. a safety pool cover (ASTM F1346-23)
    4. exit alarms on doors and windows that open directly to the pool
    5. self-closing, self-latching devices on those doors, released at least 54 inches up
    6. a pool alarm (ASTM F2208; child-worn alarms don't count)
    7. 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.
