Applicants schedule inspections through SmartGov, which supports applications, document submission, inspection scheduling, fee payment, and permit printing. The application requires approved plans to remain onsite for inspections; the Building Section conducts the necessary construction-inspection process.
Which codes and exemptions should I review?

The fee schedule identifies agricultural-exempt structures as no-fee, and the application recognizes agricultural and manufacturing exempt classifications. Some one-inspection work has flat fees rather than exemption (for example windows, roofing, sheds under 200 square feet without concrete, plumbing, electrical/HVAC, generators, and temporary buildings). Water Resource Ordinance site-plan exemptions may also apply; confirm eligibility through the portal.
