Inspections and Permitting

Permits and inspections are required for all new permanent structures and on major remodels which include changing the outside dimensions of a permanent structure, or major changes to the plumbing, electrical or mechanical systems. Fences and temporary structures typically do not require inspection or permitting but are still required to meet requirements for lot lines and easements. Non-typical construction may require permitting. The owner or contractor is responsible for meeting all applicable codes, as well as setback and zoning requirements. Any questions should be directed to City Hall at 231-9210.

You can apply for permits two ways, via our citizen portal or in person at City Hall.
