Permit triggers and exempt work for Fontana
Fontana directs applicants to obtain permission before starting projects and routes construction activity through its Building Permit and Plan Check process. The city publishes permit pathways for building work such as room additions, new construction, tenant improvements, reroofs, patio covers, sheds, windows, photovoltaic systems, and similar regulated work.

Note: Fontana does not publish a separate public handout on its permit pages listing all exemption categories. Treat exemptions as project-specific and confirm with Fontana Building & Safety before starting work, especially for work affecting structure, egress, fire/life safety, utilities, occupancy, floodplain, hillside/grading, or property-line conditions.

Application process
Application → plan check → issuance → inspection → final
- 01 Create a Build Fontana / ACA account and start the correct building plan check or permit application type.
- 02 Enter applicant and property information, including address or parcel number, then provide the project name and detailed scope.
- 03 Add the licensed professional or contractor information if applicable; the city's online guide says owner-builders do not complete the licensed-professional step.
- 04 Upload plan sets and supplemental documents in PDF format; Fontana says required plan-check submittals that do not meet its electronic file requirements will be returned unprocessed.
- 05 For projects submitted on paper, complete the Application for Building Permit and Plan Check and submit plans at the Building & Safety counter.
- 06 Plan check review begins after submittal. Fontana states first review typically takes 3 to 4 weeks, expedited solar reviews typically take 3 to 5 business days if requirements are met, and subsequent reviews typically take about 2 weeks after corrected plans are resubmitted.
- 07 After approvals and required verifications are complete, the city generates the permit invoice; fees must be paid before permit issuance.
- 08 Once fees are paid, only the signing contractor on record or the property owner may sign for the permit unless a notarized authorization is provided.
