Building Permits in Fairfield

Fairfield's Building Safety Division administers building permits, plan review and inspections.

Current codes

California's 2025 Building Standards Code (Title 24) became effective January 1, 2026. Fairfield projects must also comply with applicable local amendments and project-specific requirements.

Permits and review

Applicants should use Fairfield Building Safety's current application process. Review duration varies by project and no unsupported citywide review-time estimate is stated here.

Fees

Fairfield states that plan-check fees are due when plans are submitted and remaining building-permit fees are due at permit issuance. The City publishes current Building Safety and development-impact fee schedules, including schedules effective July 1, 2026; use the current schedule rather than a generic percentage.

Inspections and professional requirements

Inspection stages and California design-professional requirements depend on scope. No universal architect/engineer seal rule is stated here.
