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 may require proof of other governmental inspections, testing or reviews before issuing a permit, and failing to comply with codes or permit conditions voids the permit.9 Plan-review, permit and development or impact fees follow the city's fee schedule; ask the Building Division for a quote on your project.10
Mohave County's building permits do not apply here. The county's building safety code covers only unincorporated land.11
Who issues building permits in Bullhead City, and how do you reach them?
The Bullhead City Building Division issues building permits and inspections inside city limits.12 Zoning questions go to the Bullhead City Planning and Zoning Division.13 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.14
We could not confirm whether the city exempts owner-builders from building permits; ask the Building Division before you plan on it.9
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 before the city issues a certificate of compliance.15 In the RP residential park district, each manufactured-home space needs at least 3000 square feet and 36 feet of width, and park buildings are capped at 35 feet and 2 stories.1617
RVs may not serve as a permanent dwelling unit or be occupied as one in Bullhead City, though temporary construction-related use may be permitted.5 Short-term and vacation rentals are regulated under a separate city chapter in addition to other city codes.18 We could not confirm a citywide rule for tiny homes, subdivision or agricultural uses; 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, and new residential development requires city sewer to each parcel.3 For multiple-family, commercial and industrial property, the city issues a construction or installation permit only if public sewer is available or a private system is approved under Arizona Department of Environmental Quality rules or, where applicable, Mohave County Health Department requirements.19 Mohave County handles septic and well permitting under authority delegated by the state.420
Where city sewer is available, customers must accept city utility services when a certificate of occupancy issues, and existing private-sewage properties must connect within 90 days of city notice.21 A certificate of occupancy for a property on a private system carries an express condition tied to that system.22 We could not confirm a septic inspection requirement inside the city; confirm with the county.
What stays with Mohave County when you build in Bullhead City?
Septic and well permitting stay with Mohave County, 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.23
How do you build a home in Bullhead City, step by step?
- Confirm with Planning and Zoning which district your lot is in and what it allows.13
- Check that city sewer reaches the parcel, since new residential development requires it.3
- Apply to the Building Division for a building permit against the 2018 International Residential Code.126
- If a private system or well is involved, contact Mohave County Environmental Quality first.20
- Schedule inspections through the Building Division as work proceeds, and expect to accept city utilities at the certificate of occupancy.1221
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 and new residential development requires city sewer, 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.23
