Building permits in Mohave County — a northwestern Arizona county including Lake Havasu City, Kingman, and Bullhead City — are issued by Planning & Zoning Department, Building Safety Division. Mohave County enforces the 2018 IBC/IRC with Mohave County amendments.
This guide covers what requires a permit, the Mohave County Online Portal, fees, trade permits, and inspections — so your Mohave County project stays on track.
Colorado River corridor communities with growing retirement and recreation development. Mohave County handles permitting for unincorporated areas only. Cities like Kingman, Lake Havasu City, and Bullhead City manage their own permits. Extreme heat, well/septic, and flood-zone considerations are common. All contractors must hold an active Arizona ROC license.
Jurisdiction note. Mohave County permits cover unincorporated areas only. If your project is within an incorporated city or town, contact that municipality's building department.

- Structural and load-bearing alterations
- Reroofing, windows, siding, and exterior changes
- Electrical service changes and most wiring work

Mohave County trade permits
Electrical, plumbing, and mechanical work each needs its own permit and an Arizona ROC-licensed contractor in the appropriate specialty classification.
Electrical permits
Required for service installations, panel upgrades, solar PV, EV chargers, and most wiring alterations — performed by an ROC-licensed electrical contractor (C-11/R-11 classification).
Plumbing permits
Required for new plumbing, repipes, water heater changeouts, fixtures, backflow, and sewer connections — performed by an ROC-licensed plumbing contractor (C-37/R-37 classification).
Mechanical (HVAC) permits
Required for HVAC installations, changeouts, ductwork changes, and venting modifications — performed by an ROC-licensed mechanical contractor (C-39/R-39 classification).
Miscellaneous & specialty
Fencing, pools, decks, sheds, and patio covers may require special permits depending on size and utility hookups. Demolition, sign, and right-of-way permits follow separate tracks.
Verify your contractor's ROC license. Arizona licenses contractors through the Registrar of Contractors (ROC) — a contractor's license is required for any work totaling $1,000+ (labor and materials) or any work that requires a building permit, regardless of cost. Arizona uses a classification system with 60+ license types across Residential (R-), Commercial (C-), and Dual (KB/CR) categories. Property owners may act as their own general contractor on an owner-occupied residence under A.R.S. § 32-1121(B), subject to restrictions. Verify contractor licensure at roc.az.gov.
