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

The City of Bellflower (not LA County) regulates fences under Title 17, Chapter 17.72 of its Municipal Code. Residential fences may reach 6 feet in side and rear yards but are limited to 42 inches in any required front yard. Fences above 6 feet, or above 42 inches in the front, need Planning Director approval.

In Bellflower, fences within the allowed heights generally do not need discretionary approval, but Municipal Code Chapter 17.72 requires Planning Director approval for any fence over 6 feet, or over 42 inches in a required front yard. Building permits follow the California Building Code, which exempts most fences up to 7 feet.

Bellflower's Municipal Code Chapter 17.72 sets fence heights and placement, but cost-sharing of a shared boundary fence is governed by California state law — Civil Code 841 (the Good Neighbor Fence Law). The City does not adjudicate private fence-cost disputes; those are civil matters between neighbors.

Bellflower's Municipal Code does not publish a unique residential retaining-wall height table; retaining walls are governed primarily by the California Building Code that the City enforces. Under the CBC, a retaining wall up to 4 feet (measured from bottom of footing to top) is generally exempt from a building permit unless it supports a surcharge or retains hazardous liquids.

Bellflower allows common fence materials such as wood, masonry, vinyl, and wrought iron, subject to the height and location rules in Municipal Code Chapter 17.72. Chain-link is barred from front and street-side yard areas, and wrought iron is specifically recognized for taller commercial/industrial street-frontage fences.

Building a swimming pool or spa in the City of Bellflower requires a building permit from the city's Building & Safety Division before work begins. Pools and spas must meet the construction codes adopted in Municipal Code Title 15 (including the 2025 California Building and Residential Codes) plus the city's pool-enclosure standards in Chapter 15.20 and zoning setbacks in the SF zone.

Bellflower combines its own enclosure rule with California state law. Municipal Code Chapter 15.20 requires a five-foot enclosure with self-latching gates around any body of water two feet deep or more. For new and remodeled pools, the city enforces California's Swimming Pool Safety Act, which requires two of seven drowning-prevention features and anti-entrapment suction outlets, inspected by the city building official.

Bellflower Municipal Code Chapter 15.20 requires any pool, pond, wading pool or other artificial body of water two feet deep or more to be enclosed by a fence, wall or structure at least five feet high, with no openings over 50 square inches except doors or gates. Gates must be self-closing and self-latching, with the latch at least four feet above grade.

Bellflower's pool-enclosure rule covers any artificial body of water designed for immersion two feet deep or more, which includes most spas and hot tubs. Under Municipal Code Chapter 15.20, such a spa must be enclosed by a five-foot barrier with self-latching gates. New spas also fall under California's Swimming Pool Safety Act, where an approved locking safety cover can count as a barrier feature.

Bellflower's pool-enclosure rule applies to any artificial body of water two feet deep or more, which captures most above-ground and portable pools. Under Municipal Code Chapter 15.20, such pools need a fence, wall or structure at least five feet high with self-latching gates. Placement follows the SF zone's five-foot setbacks, and a building permit may be required depending on size and depth.

The City of Bellflower regulates ADUs and JADUs in Chapter 17.17 of its Zoning Code, most recently amended by Ordinance No. 1443 (adopted April 28, 2025). The chapter implements California's ADU statute, so detached and attached ADUs are reviewed ministerially with state-aligned size, height, setback, and parking standards.

Bellflower's ADU chapter (Ch. 17.17) lets owners convert an existing garage into an accessory dwelling unit, consistent with California law. Conversions of existing space are ministerial, no replacement parking may be required for a garage-to-ADU conversion, and setbacks are not imposed beyond what fire safety requires for the existing footprint.

Detached sheds and accessory buildings are governed by Bellflower's zoning code. In the SF Single Family zone (Ch. 17.16), accessory buildings may not exceed one story or 18 feet, whichever is less, and on interior lots may sit in the rear-yard setback. A shed is non-habitable: kitchens and bathrooms are prohibited unless the Planning Director approves.

Bellflower has no separate tiny-house ordinance. A tiny home on a permanent foundation can qualify as an accessory dwelling unit under Chapter 17.17, while movable tiny houses on wheels are treated as recreational vehicles under California law and may not be used as permanent dwellings on residential lots.

Bellflower regulates carports in Section 17.20.160 and the residential zone chapters. Attached carports may be located within the side-yard setback, and a carport opening onto a side street must keep at least 10 feet of driveway between the side lot line and the carport opening. Carports attached to a residence must meet the home's development standards.

Bellflower has no separate fire-pit ordinance; it adopts the California Fire Code (Municipal Code Chapter 15.40), enforced locally by the Los Angeles County Fire Department. Recreational and cooking fires must stay small, attended, and away from structures.

Open burning of trash, leaves and yard waste is effectively prohibited in Bellflower. The adopted California Fire Code bars open outdoor fires except small cooking/recreational fires, and South Coast AQMD air-quality rules restrict residential open burning across the basin.

In Bellflower, parkway (street) trees sit in the public right-of-way, and Municipal Code Section 12.08.090 makes it unlawful to remove, alter, damage, repair, or replace any tree or landscape feature in the public right-of-way without a permit from the Director of Public Works. Any parkway landscaping work must conform to the City Council-adopted Parkway Landscape Design Guidelines.

Removing a parkway or other public-right-of-way tree in Bellflower requires a permit from the Director of Public Works under Municipal Code 12.08.090. The City has no dedicated heritage- or protected-tree ordinance for private yards, but dead, decayed, diseased, or hazardous trees on private property are a public nuisance under Section 8.36.030(A)(12) and can be ordered abated.

Bellflower's Municipal Code Chapter 13.16 (Water Conservation Measures) bans watering lawns or landscaping between 10 a.m. and 5 p.m., limits irrigation to no more than two days per week, prohibits hosing down paved surfaces, and bars excessive runoff into streets. Water is delivered by private/mutual companies (Bellflower-Somerset Mutual, California American Water, Liberty Utilities, Bellflower Home Garden).
