Frequently Asked Questions
What are the specific penalties for unpermitted Retaining Wall work in urban Mohave County?
Building without authorization is considered a code violation. The local government can issue a Stop Work Order, forcing you to halt construction immediately. You may be subject to retroactive permit fees (often double the original cost), daily fines, or even a mandate to tear down the unpermitted work at your own expense.
Can a homeowner pull their own Retaining Wall permit in Arizona?
Yes, Arizona generally allows property owners to act as their own general contractor under an "Owner-Builder" exemption. However, if you choose this route, you assume full legal and financial liability for any injuries on site and must ensure all work strictly complies with the Arizona Building Code.
How long does the permit stay valid?
Once issued, most building permits in this jurisdiction remain valid for 180 days (6 months). If no inspections are scheduled or no visible progress is made within that timeframe, the permit will expire and you will have to pay renewal fees.

Navigating local building departments in Mohave County, Arizona can be confusing. Here are essential terms you should know before applying for your Retaining Wall permit:

- Easement: A designated portion of your land where the city or utility companies have the legal right to access (e.g., for power lines or sewage). You generally cannot build over an easement.

- Right-of-Way (ROW): Publicly owned land, typically sidewalks or streets. Projects like driveway paving or sewer lines often require a specific ROW permit.
