Building Permit Applications
Quick Permits is an accelerated building permit process for minor projects that qualify as "Quick Permits." Not all permit types qualify. The types of projects that would qualify would be agricultural buildings, carports, decks, garages, gazebos, retaining walls and other various small projects. Each scope of work is subject to review and may or may not qualify. All completed applications for the Quick Permit program will be plan reviewed and you will receive comments on the plans within 7 to 10 business days. See if your project qualifies by reviewing the Quick Permit Overview (PDF).
The Building and Development Division offers over-the-counter permits, which can be issued same day during regular business hours. Over-the-counter permits include the following permit types:
- Water Heater (tank-less not included)
- Minor Electrical and Plumbing
- Furnace Change-out
- Electrical service upgrades
- Agricultural electrical service
The Division also offers a same-day review for smaller projects. Same-Day Permit review is Monday through Thursday, from 8 to 10 a.m. only. Depending on the volume of traffic, expect to spend one to two hours at the Permit Center having your project reviewed. Before coming in to the office check to see if your project qualifies as a Same-Day Permit.
