Roofing permits in Tustin, CA
A plain-English starting point for roofing contractors working in Tustin (Orange County). This is general California guidance — it does not replace the requirements published by the city.
Short answer
Yes — a full or partial re-roof generally requires a permit in California. Code limits how many roofing layers may be overlaid before a tear-off is required, and Title 24 cool-roof rules apply to certain re-roofs by roof type and climate zone. Fees and whether a mid-roof inspection is required are set by the city. Roofing is generally done by a licensed C-39 contractor.
Tustin-specific fees, forms, and timelines are set by City of Tustin Community Development — Building Division. Verified data — portal, fee schedule, adopted code — is sourced below.
The general picture
Re-roofing in California generally requires a permit from the local building department. The California Building/Residential Code limits roof-covering overlays (commonly no more than two layers before a full tear-off is required) and Title 24 includes cool-roof requirements for certain re-roofs depending on roof type, slope, and climate zone. The exact fee, whether a mid-roof (in-progress) inspection is required, and the submittal format are set by each city — confirm with the jurisdiction below.
Typically needs a permit
- Full roof replacement (tear-off)
- Re-roof / overlay where allowed

Usually doesn't (general norm)
- Minor repair of a small area (patching a leak, replacing a few tiles/shingles) is often treated as maintenance
- The exact threshold — usually a roof-area limit — is set locally
- Full or partial re-roofs, overlays, and any structural deck work always require a permit
Documents & plans generally required
- Roofing permit application
