La Palma, CA Building Permits, Zoning & Septic Rules

Do you need a building permit in La Palma, California?

Yes, building and safety permits inside La Palma are issued by the city's Building & Safety Division, and permitting and inspections run online through OpenGov.¹⁴ Almost all improvement plans require plan check before a permit is issued, and some projects also need Fire or Health review.⁴

The city has adopted the 2025 California Building Standards Codes, including the 2025 California Fire Code, with local amendments.⁵ The city publishes a fee schedule for Building & Safety fees.⁷ We could not confirm the city's certificate-of-occupancy trigger or an owner-builder exemption, so ask Building & Safety.

Who handles building permits and zoning in La Palma?

La Palma's Building & Safety Division provides plan checking, permit issuance and building inspection; call 714-690-3340 or visit City Hall at 7822 Walker St., La Palma, CA 90623.¹ The Planning Division is responsible for the application and administration of the city's Zoning Code; call 714-690-3336.²

Orange County's unincorporated-area rules do not apply inside city limits, because the county's zoning code governs only unincorporated territory.⁸

Does La Palma have zoning, and what does it mean for RVs and tiny homes?

La Palma has its own Zoning Code, administered by the Planning Division.³ The division also processes conditional use permits, precise plans, residential remodels, signage, temporary use permits and design review.²

We could not confirm La Palma's minimum lot sizes, setbacks, height limits, accessory dwelling standards or tiny-home rules, and the RV provisions we found regulate parking and storage rather than living in an RV. Ask the Planning Division at 714-690-3336 before you buy or place a unit.²

How do septic permits and wells work inside La Palma?

We could not confirm which agency handles onsite septic systems or private wells inside La Palma, or whether either is allowed. Ask Building & Safety at 714-690-3340 whether a sewer and water connection is required for your lot.¹

Orange County's septic review and well permit rules apply to unincorporated land, so do not assume they govern a lot inside the city.⁹

What about flood areas in La Palma?

La Palma requires a precise plan or precise plan amendment for all proposed construction or other development in the city, including manufactured-home placement, so the city can determine whether the proposal is in a flood-prone area.⁶ Apply through the Planning Division.²
