Do you need a building permit in Bullhead City, Arizona?
Yes. Bullhead City code requires a building permit from the city's building official before any construction that the code covers begins.1 The city enforces the 2018 International Residential Code with local revisions, so plans are reviewed against that edition.6 The building official also collects plan-review, permit and development or impact fees under the city's fee schedule; ask the Building Division for a quote on your project.9
Mohave County's building permits do not apply here. The county's building safety code covers only unincorporated land.10
Who issues building permits in Bullhead City, and how do you reach them?
The Bullhead City Building Division in City Hall issues building permits and inspections inside city limits.11 Zoning questions go to the Bullhead City Planning and Zoning Division.12 Factory-built homes in the R1FB district get an inspection from the development services director after the permit is issued and the home is placed on the lot.13
We could not confirm whether the city issues a certificate of occupancy for every new home or exempts owner-builders; ask the Building Division before you plan on either.
Does Bullhead City have zoning, and what does it mean for homes and RVs?
Yes. Bullhead City zones land inside its limits by district, and each district has its own permitted uses.2 In the R1L single-family district, a conventionally built house must have at least 672 square feet of livable floor area.7 Manufactured homes in the R1MH district need a driveway at least 12 feet wide.14 In the RP residential park district, each manufactured-home space needs at least 3000 square feet and 36 feet of width.15
RVs may not serve as a permanent dwelling unit or be occupied as one in Bullhead City.5 We could not confirm a citywide rule for tiny homes; ask Planning and Zoning which district your lot is in before you buy.
How do septic permits work in Bullhead City?
Inside Bullhead City, private septic is the exception. City code makes it unlawful to construct or maintain a privy, septic tank, cesspool or similar facility except as the sewage section allows.3 Where a private system is allowed, it must be approved and permitted under Arizona Department of Environmental Quality rules or, where applicable, under Mohave County requirements.16 Mohave County Environmental Quality handles septic and well permitting under authority delegated by the state.417
Because septic is not a city-permit matter, a building permit from the city does not replace a septic approval. We could not confirm a city septic inspection requirement; confirm with the county.
What stays with Mohave County when you build in Bullhead City?
Septic and well permitting stay with Mohave County Environmental Quality, not the city.4 Anyone drilling, deepening or replacing a well outside an Active Management Area must file Arizona Department of Water Resources Form DWR 55-40 beforehand.8 We could not confirm a separate city well permit; ask the city before you drill.
The county's zoning, building permit and RV rules apply only to unincorporated Mohave County. If your parcel has a Bullhead City address but sits outside city limits, check with Mohave County Development Services on which jurisdiction applies.18
Building a home in Bullhead City: the steps, in order
- Confirm with Planning and Zoning which district your lot is in and what it allows.12
- Check that city sewer reaches the parcel, since private septic is restricted inside the city.3
- Apply to the Building Division for a building permit against the 2018 International Residential Code.116
- If a private system or well is involved, contact Mohave County Environmental Quality first.17
- Schedule inspections through the Building Division as work proceeds.11
Watch-outs
- Recreational vehicles cannot be occupied as a permanent dwelling in Bullhead City, so buying a lot to live in an RV does not work inside city limits.5
- Private septic systems are generally unlawful inside Bullhead City, so confirm sewer access before buying a lot.3
- Mohave County's unincorporated-land rules do not apply inside the city; confirm whether a parcel is inside city limits before relying on either set of rules.18
