Building Permits in Sunnyvale

Sunnyvale's One-Stop Permit Center coordinates development review by Building, Fire, Planning, and Public Works Engineering. The city provides E-OneStop Online Services for permit-related work.

Current Code Framework

The 2025 California Building Standards Code (Title 24) became effective January 1, 2026. Sunnyvale projects must comply with the applicable state code parts plus current local ordinances and amendments.

Plan Review and Submittal

The Permit Center provides plan-check services and identifies a dedicated plan-check submittal contact. Requirements vary by project and reviewing discipline, so applicants should use the current project checklist rather than a generic document list.

Certificate of Occupancy

Sunnyvale's Permit Center notes project-specific conditions that can affect issuance of a Certificate of Occupancy. Occupancy approval depends on the applicable permit, inspections, and other city requirements; it is not automatically required for every minor permit.

Fees and Timing

Fees and review timing depend on project type, scope, and required reviewing divisions. No generic fee percentage or review duration is stated here without a city source supporting it for the specific permit.

Inspections

Required inspections are determined by the approved work and applicable code. Use E-OneStop/Permit Center instructions for the actual permit.
