Before You Build in Pleasanton, CA: Permit & Rule Checklist (2026)

Pleasanton Municipal Code Chapter 18.84 caps fences, walls, and hedges in side and rear yards at six feet. Front yards are limited to 30 inches for solid fencing and 42 inches for open fencing. Taller fences up to eight feet require zoning administrator approval and design review.

Pleasanton requires Administrative Design Review for fences, walls, and hedges over six feet but not over eight feet in side or rear yards. Under the California Residential Code, wood fences up to seven feet and retaining walls up to four feet are exempt from a building permit, though zoning height limits still apply.

Pleasanton's Municipal Code sets fence heights and placement, but cost-sharing for a boundary fence between neighbors is governed by California's Good Neighbor Fence Law (Civil Code 841). Adjoining owners are presumed equally responsible for reasonable costs, and 30 days' written notice is required before incurring expenses.

Pleasanton's zoning code (PMC 18.84.090) allows retaining walls to occupy required side and rear yards along with walks and driveways. Under the California Residential Code, a retaining wall not over four feet (bottom of footing to top of wall) is exempt from a building permit unless it supports a surcharge.

Pleasanton allows common residential fence materials including wood, wrought iron, chainlink, brick, and split-face block, regulated through the solid-versus-open distinction in Chapter 18.84. Material choice affects allowed height, and over-height fences are subject to design review. Planned-development and HOA standards may impose stricter material rules.

Pleasanton requires a building permit to construct a residential swimming pool or spa, processed over the counter or through plan review and submitted through the city's Accela Citizen Access portal. Plans must show pool dimensions, distances to property lines and structures, equipment location, and the selected drowning-prevention measures.

Pleasanton requires a minimum 60-inch tall fence, barrier, or enclosure completely surrounding every pool holding water over 18 inches deep. The ground gap must be under 2 inches, no opening may pass a 4-inch sphere, and gates must open away from the pool and be self-closing with a latch at least 60 inches up.

Pleasanton requires at least two of seven drowning-prevention safety features for any new or remodeled residential pool or spa, per its pool and spa review requirements (Municipal Code Chapter 20.55 / CBC 3109 / HSC 115921-115929). Options include an isolating enclosure, ASTM mesh fence, safety cover, door alarms, self-latching door devices, and pool alarms.

Pleasanton's swimming pool definition expressly includes above-ground and on-ground pools holding water over 18 inches deep, so the same 60-inch barrier and two-of-seven drowning-prevention rules apply. Above-ground pools must also be shown on plans with distances to property lines, structures, and trees.

Pleasanton treats hot tubs, spas, and portable spas as swimming pools when they hold water over 18 inches deep, so the 60-inch barrier and two-of-seven drowning-prevention rules apply. Equipment must meet California Electrical Code Article 680 bonding and GFCI rules, and new homes after Jan 1, 2023 cannot use gas heaters.

Pleasanton allows one ADU plus one JADU on single-family lots under Municipal Code Section 18.106, consistent with California ADU law. New detached ADUs may be up to 1,000 sq ft, capped at 16 feet tall with 4-foot side and rear setbacks. Owner occupancy is not required for ADUs approved between 2020 and 2025.

Pleasanton allows garage-to-ADU conversions under Municipal Code Section 18.106. When a garage is converted to an ADU, the lost off-street parking spaces do not have to be replaced. A converted accessory structure may keep its existing height and setbacks, but any addition must meet current ADU development standards.

Pleasanton treats sheds as Class I or Class II accessory structures under Municipal Code Section 18.84.160. They may sit in a rear or interior side yard within 35 feet of the rear lot line, and Class II structures may be built to the property line. No accessory structure is allowed in a front yard.

Under Pleasanton Municipal Code Chapter 18.84, carports are limited to the rear yard. A garage or carport serving a dwelling needs a 23-foot front yard (15 feet if entered parallel to the street) and a 20-foot side yard on a corner lot's street side. Demolishing a carport for an ADU does not require replacing the parking.

Pleasanton has no dedicated tiny-home ordinance. A tiny home on wheels meets the city's recreational-vehicle definition (400 sq ft or less, single chassis) and cannot be used for permanent living. Under Chapter 18.84, no trailer may be occupied for living unless in a licensed trailer park. A permanent tiny home generally must meet ADU standards under PMC 18.106.

Pleasanton has no city ordinance banning backyard fire pits outright, but use is governed by the adopted California Fire Code (PMC Chapter 20.24), Livermore-Pleasanton Fire Department fire-danger-level restrictions, and Bay Area Air Quality Management District (BAAQMD) wood-smoke rules. Wood-burning fire pits are illegal during a Spare the Air Alert.

Open burning in Pleasanton is tightly restricted. The Bay Area Air Quality Management District (BAAQMD) Regulation 5 generally prohibits open burning across the region, allowing only limited categories on designated permissive burn days with an Air District permit. The city's adopted California Fire Code (PMC Ch. 20.24) also governs open and recreational fires.

Normal maintenance pruning of a Protected Tree does not require a permit in Pleasanton, but all pruning must follow ISA Best Management Practices and ANSI A300 standards. Topping is prohibited unless specifically approved, and improper pruning of a Protected Tree can trigger civil penalties.

Removing a 'Protected Tree' in Pleasanton requires a permit from the Community Development Director. Listed native species are protected at 37 inches trunk circumference; other species at 55 inches. Unlawful removal carries a civil penalty of $100 per inch of circumference or the appraised value, whichever is greater.

Pleasanton, supplied by wholesaler Zone 7 Water Agency, restricts outdoor irrigation to between 9 p.m. and 6 a.m. and prohibits watering during and within 48 hours of measurable rainfall. Potable water may not be used to power-wash hardscapes, and irrigation runoff must be eliminated.
