The city follows California Building Code standards, and permits help ensure work meets seismic, wind, and fire safety requirements.

Permit Process
Project Assessment
A licensed roofing contractor typically assesses your project to determine permit requirements. They'll evaluate the scope of work, structural considerations, and materials to be used. For commercial projects, this may involve architectural drawings or engineering calculations.
Application Submission
The contractor or property owner submits permit applications to Antioch's Building Division. Required documents often include project plans, material specifications, contractor license information, and property details. Commercial projects may require additional documentation.
Plan Review
City reviewers examine submitted plans for compliance with building codes, zoning regulations, and energy efficiency standards. This review ensures structural integrity, proper drainage, and fire safety compliance. Review times vary based on project complexity.
Permit Issuance
Once approved, permits are issued with associated fees. The permit must be posted visibly at the job site throughout construction. Some projects may require multiple inspections at different stages of completion.
Inspections
City inspectors visit the site at key milestones: after tear-off (to inspect roof deck), during installation, and upon completion. Final inspection confirms work meets code requirements before the permit is closed.
Final Approval
After passing all required inspections, the city issues final approval. This documentation should be kept with property records for insurance purposes and future property transactions.
Compliance Tips
- ✓ Verify contractor licensing - Ensure your roofing contractor holds current California CSLB licensing and Antioch business registration
- ✓ Get multiple quotes - Compare proposals that include permit costs, inspection fees, and compliance documentation
- ✓ Review insurance coverage - Confirm your contractor carries workers' compensation and liability insurance for roofing work
- ✓ Document everything - Keep copies of permits, inspection reports, and manufacturer warranties for future reference
- ✓ Plan for weather delays - Permit timelines may extend during rainy seasons when roofing work is restricted
- ✓ Consider energy efficiency - Antioch may have specific requirements for cool roofing materials or insulation upgrades

- Mixed-use areas - Additional fire separation requirements
- Coastal influence zones - Special wind uplift requirements may apply
