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

California Civil Code §841 (the Good Neighbor Fence Act) presumes shared boundary fences are a mutual benefit and requires neighbors to split reasonable costs of construction and maintenance. Fresno does not override this; disputes go to small claims court. Written 30-day notice to the neighbor is required before any cost-share project.

Retaining walls in Fresno require a building permit when they are 4 feet or taller measured from bottom of footing to top, or at any height when they support a surcharge load (slope, driveway, structure). Engineered plans stamped by a California licensed engineer are required for walls over 4 feet.

Under California Health and Safety Code §115920 (the Swimming Pool Safety Act) and FMC Chapter 15, all swimming pools in Fresno must have at least two drowning prevention safety features. Enclosure fencing must be at least 60 inches tall with self-closing, self-latching gates that open outward away from the pool.

A standard residential fence not over 7 feet does not require a building permit in Fresno, but it must still meet the zoning standards of Section 15-2006; fences in the public right-of-way need an encroachment permit, and security/barbed-wire fencing requires a separate permit under Section 15-2009.

Fresno limits fences in the required front yard to 3 feet (4 feet if 80% open wrought iron/tubular steel), allows up to 6 feet in interior side, rear, and street-side yards, and caps overall fence height at 7 feet, all governed by Fresno Municipal Code Section 15-2006.

Hot tubs and spas require a building permit from Fresno Development Services. Must have an approved safety cover (ASTM F1346) OR comply with 60-inch barrier rules per CA §115922. Electrical permit required for 240V installations.

Beyond the H&S §115920 two-feature enclosure rule, Fresno pool operators must comply with the Virginia Graeme Baker Pool and Spa Safety Act (VGB) for anti-entrapment drain covers, NEC Article 680 for electrical bonding and GFCI protection, and FMC §10-105 noise limits on pool equipment. Commercial and STR pools have additional California public pool rules under H&S §116025.

Building a swimming pool or spa in Fresno requires a construction permit, and whenever that permit is issued for a new or remodeled pool the pool must be equipped with at least two of seven specified drowning-prevention safety features under Health & Safety Code 115922. Only small prefabricated above-ground pools accessory to a single-family home that are less than 24 inches deep and hold no more than 5,000 gallons are exempt from the building permit.

Above-ground pools holding 18 inches or more of water require a building permit in Fresno. Must comply with CA Swimming Pool Safety Act (§115920-115929) 60-inch barrier requirement. Pool ladders must be removable or lockable.

Every residential swimming pool, spa, or hot tub in Fresno that holds more than 18 inches of water must be surrounded by an enclosure at least 60 inches high, with self-closing, self-latching gates that open away from the pool. The City enforces the California Swimming Pool Safety Act (Health & Safety Code 115920-115929) through the 2022 California Residential Code, and the City's own Consumer Notice reproduces the barrier standard verbatim.

Converting a garage to living space in Fresno generally means creating an Accessory Dwelling Unit under Fresno Municipal Code Section 15-2754, and California Government Code Section 66314 bars the City from requiring replacement of the parking spaces lost when a garage is converted to or demolished for an ADU.

Fresno permits Accessory Dwelling Units (called Second Dwelling Units, Backyard Cottages, and Accessory Living Quarters) on any residential lot under Fresno Municipal Code Section 15-2754, but California state law (Gov. Code 66314-66323) now overrides stricter local standards, requiring ministerial approval of an 800 sq ft detached ADU with 4-foot side and rear setbacks.

Carports allowed as accessory structures in residential zones per Fresno Municipal Code (FMC) Title 15 (Citywide Development Code). Must meet setbacks for primary structure in most zones; attached carports follow garage standards. Building permit required.

Fresno allows tiny homes primarily as ADUs under CA Gov Code §65852.2 and FMC accessory-dwelling-unit provisions. Tiny homes on wheels permitted only as Movable Tiny Houses (MTH) meeting HCD standards, not as permanent dwellings on private lots.

In Fresno a one-story detached tool/storage shed of 120 square feet or less, no more than 12 feet high, and at least 3 feet from property lines needs no building permit; accessory structures on residential parcels of 10,000 sq ft or less are capped at 12 feet high and must comply with Fresno Municipal Code Section 15-2004.

Open burning is prohibited within the City of Fresno except with an operational permit issued under the Fresno Municipal Code and San Joaquin Valley Air District rules, or for limited cooking, campfire and religious-ceremonial fires using clean dry wood or charcoal. Burning trash is always illegal. Company officers may extinguish any non-compliant fire on the spot.

Backyard fire pits, fire rings, burn bowls and chimineas are legal in Fresno for cooking or recreation, but the San Joaquin Valley Air Pollution Control District (SJVAPCD) Rule 4901 prohibits operating any outdoor wood-burning device on declared 'Check Before You Burn' curtailment days from November 1 through February. Fresno is a Rule 4901 'hot spot' county with the strictest curtailment thresholds.

The Fresno Water Division enforces year-round watering rules: no watering between 9 AM and 6 PM, no runoff onto streets or sidewalks, and watering on assigned odd/even days based on address. Mandatory schedules tighten in drought stages declared by Fresno and the State Water Board under Water Code §10608 and SB 606/AB 1668 long-term conservation rules.

Street trees in the Fresno public right-of-way are jointly the responsibility of the property owner and the city Urban Forestry division. Property owners must maintain 14-foot clearance over streets and 8 feet over sidewalks under FMC §13-605. Removal or major pruning of street trees and protected trees requires a permit from Urban Forestry.

FMC §13-305 requires a Tree Removal Permit for protected/heritage trees. Permits evaluated by licensed arborists. Licensed contractor required. Fruit trees exempt. Violators must pay double fee plus replacement costs.
