Zoning, building permits and septic rules in Palmdale, California

The City of Palmdale, California adopts its own zoning ordinance and its own Building and Safety office handles building permits inside city limits12. Septic systems for a Palmdale address are tied to Los Angeles County Public Health rather than the city3. Los Angeles County's unincorporated-area rules do not apply inside the city.

Does Palmdale, CA have zoning, and what does it mean for lot size and setbacks?

Yes. The City of Palmdale adopts and administers its own zoning ordinance, Title 17 of the municipal code, for land inside city limits1. The city's residential districts include Residential Neighborhood zones RN 1 through RN 4 and single-family zones ER, LDR, SFR 1, SFR 2, SFR 3 and RN 1 through RN 34. Which district a parcel sits in decides everything else, so look it up on the city's zoning map before you make an offer10.

Standards differ by district. In the ER district, buildings may cover at most 20% of the lot and the main house is limited to 35 feet and 2 stories1112. In the SFR 2 district, lot coverage rises to 40% and the height limit stays at 35 feet and 2 stories76.

We could not confirm Palmdale's minimum lot area, minimum home size or setbacks by district. Ask the city's Planning office at the number listed below.

Land divisions inside Palmdale fall under Title 16 of the municipal code13.

Do you need a building permit in Palmdale, and who issues it?

Palmdale's own Building and Safety office regulates construction of new, remodeled and existing residential buildings inside the city, and every permit application goes through the city's Accela Citizen Portal2. Los Angeles County Public Works issues building permits for unincorporated land, not for Palmdale addresses14.

Construction in Palmdale is governed by the Palmdale Building Code, which adopts the 2025 California Building Code with local amendments5.

Owner-builders get a state exemption from contractor licensing, but California treats it as a licensing exemption only, not a building-permit exemption, and owner-builders who sign a permit application still have to pass inspections1516. We could not confirm Palmdale's fee amounts or a list of work that is exempt from permits; ask Building and Safety.

Who do you call at Palmdale Building and Safety and Planning?

Building and Safety takes questions about permit applications at 661-267-5353 and sits at 38250 Sierra Highway in Palmdale2. Palmdale Planning, which handles the zoning ordinance, zoning map and planning applications, is at the same address at 661-267-520010. Septic questions go to Los Angeles County Public Health's Onsite Wastewater Treatment Program at (626) 430-538017.

A reader inside Palmdale city limits should not use the Los Angeles County Planning counter for zoning or the county's Public Works district offices for building permits; those serve unincorporated land only1814.

How do septic permits work inside Palmdale?

Septic is the piece that does not belong to the city. The Palmdale code says accessory dwelling units must connect to water, electric and sewer, or to septic where approved by the county health department3. California requires a permit for every new or replacement septic system, issued by the local city, county or special-district agency that runs the program19.

Los Angeles County Public Health reviews septic plans under its Local Agency Management Program for unincorporated areas and contracted cities20. We could not confirm the exact rule for a new septic system on a Palmdale lot, including any requirement to connect to a public sewer, so call the Onsite Wastewater Treatment Program before you plan on septic17.

Wells work the same way: the County Drinking Water Program reviews and approves wells across Los Angeles County, with exceptions only for Long Beach, Pasadena and Vernon21.

Can you live in an RV or tiny home in Palmdale?

We could not confirm Palmdale's own rule for living in an RV, tiny home or manufactured home on a city lot. California law says RVs are not intended as permanent dwellings and, unless a local ordinance allows otherwise, may generally be occupied only in mobilehome parks or special occupancy parks9.

A tiny home on wheels with 400 square feet or less of floor area is treated as an RV in California, while a tiny home on a foundation must meet the California Building Standards Code or factory-built housing standards22. Los Angeles County's ban on RV living applies to unincorporated land, not to Palmdale23. Ask Palmdale Planning before parking an RV or placing a tiny home10.

For a backyard unit, state law requires accessory dwelling unit applications to be approved ministerially, without a hearing24.

Building a home in Palmdale: the steps, in order

  1. Find the parcel's zoning district on the city's zoning map and confirm height, lot coverage and setbacks with Palmdale Planning10.
  2. Ask the County Onsite Wastewater Treatment Program whether the lot needs septic or can connect to sewer17.
  3. Apply for the building permit through the Accela Citizen Portal; plan review is done electronically2.
  4. Build to the 2025 California Building Code with Palmdale's amendments5.
  5. Schedule inspections online through the same portal2.
  6. If a driveway meets a state highway, apply to Caltrans for an encroachment permit25.

What stays with Los Angeles County, and what to check before you buy in Palmdale?

Septic and well permits stay with Los Angeles County Public Health rather than the city321. For land outside Palmdale city limits, see the Los Angeles County page, where unincorporated rules differ.

County-level figures: Los Angeles County's effective property tax rate is 0.7% and its median property tax bill is $5,438 per year2627. USDA rates only 6.6% of the county's soils as not limited for a conventional septic drain field, so many lots need a site evaluation or engineered system28. The county sees about 15.1 inches of precipitation a year and severe drought in about 40.8% of years2930.

Watch-outs

  • Palmdale's permit fees, any list of work exempt from building permits, minimum lot area and setbacks by district were not confirmed; Building and Safety at 661-267-5353 and Planning at 661-267-5200 can answer them210.
  • Whether a new septic system is allowed on a particular Palmdale lot, instead of a public sewer connection, was not confirmed; ask the County Onsite Wastewater Treatment Program17.
  • Rules found for unincorporated Los Angeles County, such as its RV ban and its 800-square-foot minimum home size, do not apply inside Palmdale city limits2331.
  • Palmdale's zoning and height figures come from its residential development table; other districts and special overlays may differ, so check the parcel's district4.
