All new construction and major remodels in Thousand Oaks must meet the California Green Building Standards Code (CALGreen, Title 24 Part 11). The city building division verifies water, energy, materials, and indoor-air quality measures during plan check and inspection.
Thousand Oaks enforces CALGreen, the state's mandatory green building code under Title 24 Part 11, through TOMC Title 15. Mandatory measures cover water-efficient fixtures, electric-vehicle-ready parking, construction-waste diversion, low-VOC finishes, and indoor air quality. The city aligns CALGreen with its 2024 Climate Action Plan and 2018 Sustainability Action Plan, and may add Tier 1 or Tier 2 voluntary measures for specific projects. Plan submittals require a CALGreen checklist and verification of compliance during construction inspections by city staff.
Missing CALGreen documentation, noncompliant fixtures, or skipped EV-ready conduit can delay permit issuance, final inspection, and certificate of occupancy.
