Building & Construction Permits

New construction or remodel?  Here are the permits and application forms you will need in order to apply for City approval of your project.  Review and final approval can take from 2-4 weeks.  Note that you will also need to apply for a building permit from the Mid-Columbia Building Codes office once you receive site plan approval from the City of Mosier. 

The City Office has complete application packets available– stop by to pick one up.

Please call ahead to make an appointment if you need to come into the office to submit an application or if you have specific questions about an application.
