Does Brawley, California have zoning, and what does it mean for RVs and tiny homes?

Yes. The City of Brawley adopts and administers Chapter 27, the Brawley Zoning Ordinance, for land inside city limits, with district-specific standards1. The residential districts the ordinance lists are R-A, R-E, R-1, R-2, R-3, MHS and MHP8. Zoning questions go to the Planning and Zoning Department, which handles conditional use permits, zone changes, variances and lot line adjustments9.

RVs: A recreational vehicle park must be in the MHP (mobilehome park) zone4. Camping on private property is unlawful unless the land is appropriately zoned under the Brawley Zoning Ordinance, though owners and people with written owner permission may camp if zoning and health rules are met5. Parking an RV on a city street is limited to 12 hours without written police authorization4.

Tiny homes and manufactured homes: We could not confirm a Brawley rule specific to tiny homes; ask the Planning and Zoning Department. Permanent manufactured homes on individual lots belong in the MHS zone10.

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

The City of Brawley Building Division handles building permits inside city limits and publishes a building permit application and a building permit fees packet2. Contractors must hold a city contractor's business license before working in Brawley2. Brawley's own code sections we reviewed spell out permit rules for swimming pools, spas and hot tubs11; we did not confirm a general owner-builder exemption or fee amounts, so ask the Building Division before you pour a slab2.

California owner-builders who sign a building permit application must pull all building permits and pass inspections12.

The county's building rules apply to unincorporated land, not to parcels inside Brawley. For land outside city limits, see the Imperial County page.

How do septic permits work inside Brawley?

We could not confirm which agency permits septic systems inside Brawley city limits. Imperial County's Environmental Health Division reviews septic design plans and inspects septic construction in the county, and it reviews building permit applications on lots served by septic systems3. Imperial County's local septic program applies inside city limits only where the city has given written authorization; otherwise the state's Tier 1 standards apply13. Ask the Building Division whether your parcel has a sewer connection, and contact Environmental Health if it does not3.

If your lot sits in a mapped flood hazard area, Brawley's flood rules also require on-site waste disposal systems to be located to avoid impairment or contamination during flooding7.

Building a home in Brawley: the steps, in order

  1. Confirm the zoning district for your parcel with the Planning and Zoning Department9.
  2. Check the district's lot rules. In the A-1 Light Agricultural district, the minimum lot size for proposed subdivisions is 40 acres14, and building coverage is 2.5% on lots of 40 acres and greater15. In R-1, the primary structure is limited to two stories or 35 feet, whichever is less16.
  3. Ask whether the parcel is in a special flood hazard area, which brings added construction standards7.
  4. Settle sewer or septic with the Building Division and the county Environmental Health Division3.
  5. File the building permit application and fee packet with the Building Division2.
  6. Hire a contractor with a city business license, or sign as owner-builder and accept responsibility for the project212.

Accessory dwelling units are allowed on residentially zoned lots with an existing or proposed home; a statewide exemption ADU can be up to 800 square feet6.

What stays with Imperial County, and what to check before you buy

Brawley decides zoning and building permits inside city limits, but it does not decide everything. Septic systems follow the county Environmental Health Division's program or the state's policy3. Water wells in Imperial County are permitted through the county rather than the city17. Driveways that connect to a state highway need a Caltrans encroachment permit18.

For land outside city limits, use the Imperial County page. Imperial County's farmland value is about $11,892 per acre19, its effective property tax rate is 0.8%20, and annual precipitation is only 3.2 inches21, so water supply and irrigation access deserve a close look before you buy.

Watch-outs

  • Brawley's code sections we reviewed do not state a general building permit rule, fee amounts, an owner-builder exemption or a septic authority; ask the Building Division before you commit11.
  • The county's rules apply to unincorporated Imperial County, not to parcels inside Brawley city limits22.
  • Street parking an RV in Brawley is limited to 12 hours unless the chief of police or a delegate authorizes it in writing4.
