Building permits, zoning and septic rules in Shafter, California

Inside the City of Shafter, California, building permits come from the city's Building Department, which enforces the building code throughout the incorporated city1. Shafter applies the 2022 California Residential Code to new one- and two-family homes2. Zoning is city-run too, and it limits RVs3. We could not confirm who issues septic permits inside the city; Kern County Environmental Health is the office to ask.

Do you need a building permit in Shafter, California?

Yes. The City of Shafter's Building Department states its building code standards are enforced throughout the incorporated city, and it issues building permits and performs inspections1. Kern County's Public Works building office serves unincorporated land, not addresses inside Shafter.

Shafter's code adopts the 2022 California Residential Code, with local amendments, for detached one- and two-family dwellings and townhouses of no more than three stories2. California law also requires a separate permit for each building or structure before work begins8.

Building yourself? California's owner-builder exemption from contractor licensing exists, but none of the improvements may be intended or offered for sale9. We could not confirm whether Shafter adds its own owner-builder rules, so ask the Building Department.

Who handles building permits in Shafter, and how do you reach them?

The City of Shafter Building Department handles building permits and inspections at 336 Pacific Ave, Shafter, CA 93263, by phone at 661-746-50021. Online submittals are not accepted, so applications are delivered in person or by mail1.

A driveway, curb or sidewalk on a public street or right-of-way inside Shafter needs a written application and a permit from the city clerk, including when an existing driveway is relocated6. Driveway connections onto a state highway are a separate matter and need a Caltrans encroachment permit10.

Does Shafter have zoning, and what does it mean for RVs and mobile homes?

Shafter has its own land use zoning ordinance, and the city's rules for RVs and mobile homes both say they must comply with it34. Kern County's zoning ordinance covers unincorporated land only and excludes incorporated cities11. We could not confirm Shafter's lot sizes, setbacks or minimum home size, because the zoning district standards were not verified; call the city before you buy.

Outside an RV or trailer park, Shafter lets RVs be stored dead where zoning permits on a property with an existing conforming use, and allows private recreational use only when the Planning Commission or City Council approves it3. Mobile homes outside mobile home parks are limited to one per parcel in most cases and must carry a state HCD insignia of approval4.

How do septic permits and sewer connections work in Shafter?

Shafter requires a building used by people to connect to the public sewer within 90 days of completion when the building is within 100 feet of the public sewerage system5. We could not confirm whether the city or the county issues septic permits for addresses that are outside that distance, so ask Kern County Environmental Health before you plan on a septic system7.

For reference, California's statewide septic rules leave permitting to a county, city or special district local agency12. Wells are likewise permitted locally, through the local environmental health agency or water district13. We could not confirm Shafter's water connection rule.

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

RV living in Shafter is limited. Private recreational use of an RV outside a park needs approval from the Planning Commission or City Council, and the building official can approve a temporary RV only at a construction site3. California treats RVs as not intended for permanent dwellings14.

Tiny homes are allowed under state rules when they are approved as a recognized housing type, such as a manufactured home or a home built to the California Residential Code15. Shafter's own tiny home and accessory dwelling rules were not confirmed. State law requires ministerial approval of accessory dwelling units that meet its standards16.

Building a home in Shafter: the steps, in order

  1. Call the Building Department at 661-746-5002 to confirm the zoning district, design requirements and plan-submittal rules for your parcel1.
  2. Ask the city about water and sewer. A building within 100 feet of the public sewer must connect within 90 days of completion5.
  3. Submit plans in person or by mail, since online submittals are not accepted1.
  4. Plan to the 2022 California Residential Code as amended by Shafter2.
  5. Get a city clerk driveway permit for any driveway on a public street6.
  6. Confirm any septic permit with Kern County Environmental Health7.

What stays with Kern County, and what to check before you buy in Shafter?

Land outside Shafter's city limits follows Kern County's rules instead; see the Kern County page for unincorporated land. Kern County Environmental Health runs septic permitting for unincorporated Kern County17.

Countywide figures: Kern County's effective property tax rate is 0.9%18 and the median property tax bill is about $2,833 a year19. A typical home is valued around $366,23820. Annual precipitation averages 8.9 inches21, and the county is in severe drought in 41.5% of years22.

Watch-outs

  • Shafter's zoning ordinance, including lot sizes, setbacks and ADU rules, was not confirmed; ask the City of Shafter Building Department before you commit to a parcel1.
  • Do not assume Kern County's rules apply inside Shafter: the county's zoning layer excludes incorporated cities11.
  • RVs cannot simply be lived in on a Shafter lot; private recreational use needs Planning Commission or City Council approval3.

Unanswered questions are usually a sign that Shafter publishes no rule on the point, not that none exists. Kern County’s page lists the county offices to call.
