Installing a new or replacement manufactured home within a floodplain requires many steps to complete successfully. In addition to obtaining a floodplain use permit and manufactured home permit from Pinal County, property owners must also obtain a permit from the Arizona Office of Manufactured Housing. Here are the typical steps that must be taken to properly permit and install your new home:
- Email the Pinal County Flood Control District or call 520-866-6411 to see if a base flood elevation or depth has been determined for your property.
- Hire an engineer to develop a foundation plan for the home that complies with the Pinal County Floodplain Ordinance, the elevation requirements, and all applicable Manufactured Home Regulations. The engineer needs to also complete a pre-construction elevation certificate. Alternatively, you can have a surveyor complete the elevation certificate that goes along with the plans. A temporary benchmark should be placed on the property to ensure that the foundation is built up high enough and/or so the installer knows how high the home needs to be.
- Apply for a Floodplain Use Permit with Pinal County and submit your plans and elevation certificate for review.
- If the plans and elevation are acceptable you will received an acceptance letter from the Flood Control District. You will then need to apply for a manufactured home permit with the state of Arizona.
- If the state of Arizona approves your plans you will need to bring three approved copies of back to Pinal County and your Floodplain Use Permit will be issued.
- Install the home following the plans and receive the required inspections by Pinal County Staff
- Call the surveyor back out to the property to complete a final construction elevation certificate. Submit a copy of the elevation certificate to Pinal County for Review.
- Once the elevation certificate is approved you will get your electrical clearance or certificate for occupancy.
