Codes, exemptions & field inspections
Build to the adopted code. Verify every exception.
This guide translates the available agency record into a preconstruction checklist for structural scope, minor work, and inspection release. The adopted code and the issuing official control when a field condition is disputed.
Inspection lane
Provide the applicant's name, job-site address, telephone number, permit number, and requested inspection date. Submit inspection requests one or two days in advance and copy the applicable supervisor when emailing; status can be checked through the county's online permit system.
Minor-work playbook
Understand what may be exempt—and what is not.
An Agricultural Building Exemption Form is published among the county's building forms; the public page does not state the full exemption criteria. All other exemption determinations should be confirmed with the Building Division.
Field rule
A permit exemption generally addresses one narrow construction trigger. It does not automatically waive zoning, land-use, floodplain, shoreline, fire, energy, electrical, utility, septic, or right-of-way requirements. Obtain written confirmation when the project involves a new structure, structural alteration, change in occupancy, or concealed work.

- 3
Close the record
Retain the approved plans, inspection approvals, correction responses, and final certificate or occupancy release with the property file.
Contractor verification
Verify the builder before the contract is signed.
Use the state licensing system to verify active registration, trade credentials, bond status, and liability coverage where available. Match the legal business name to the proposal and permit application.
Planning reference
Keep the parcel rules beside the building plans.
A building permit is only one part of statutory compliance. Check the local zoning, ordinance, map, or land-use reference before finalizing setbacks, height, lot coverage, access, drainage, or accessory structure placement.
