HVAC Installation · Ventura County, California
In California, a HVAC Installation requires a mechanical permit.
Ventura County requires a mechanical permit for HVAC work in the unincorporated county, but offers an "Express Insta-Permit" option for simple like-for-like replacements (HVAC change-outs, water heaters, re-roofing) that issues immediately without plan review, through the mandatory VC Citizen Access Portal. As of January 1, 2026, the county stopped accepting paper plan submittals entirely, requiring high-resolution PDFs for all new applications under the newly adopted 2025 Title 24 code cycle. Plans are reviewed under the Ventura County Building and Safety Division (unincorporated code (IRC 2025 California Buil); apply through Ventura County Building & Safety before work begins.
