Thousand Oaks Energy Efficiency Code for New Buildings

Environmental Protection California 4 Minutes Read · published February 21, 2026 Flag of California

Thousand Oaks, California requires new construction to meet state and local energy-efficiency requirements as part of the building permit and inspection process. This guide explains what designers, builders, and owners need to know to document compliance, submit the right permits and forms, and pass energy inspections so projects open on schedule. It summarizes applicable California energy standards, the city enforcement pathway, practical steps for plan review and on-site verification, and where to get official forms and help from the City’s Building & Safety office[1].

What the energy code requires

New buildings in Thousand Oaks must demonstrate compliance with California’s Building Energy Efficiency Standards (Title 24) at plan review and during inspections. Typical documentation and requirements include:

  • Energy compliance forms and reports (CF1R, documentation of mandatory measures).
  • Performance or prescriptive compliance paths with modeled energy calculations.
  • Installation of HVAC, lighting controls, insulation and fenestration per approved plans.
  • On-site verification and testing at required inspection stages.
Verify Title 24 compliance early in design to reduce costly rework at inspection.

Penalties & Enforcement

The City of Thousand Oaks enforces energy and building code compliance through the Community Development Department, Building & Safety division. Enforcement actions can include notices to comply, stop-work orders, withholding of inspections, and permit denial or revocation; specific fine amounts and escalation schedules are not specified on the cited building department pages[1].

  • Immediate remedies: correction notice and required corrective work.
  • Administrative actions: stop-work order or withholding certificate of occupancy.
  • Legal referral: civil or criminal prosecution where the municipal code provides penalties (amounts not specified on the cited pages).
If a stop-work order is issued, do not continue work until the Building & Safety office authorizes resumption.

California’s Title 24 sets mandatory energy standards that the city applies at plan check and inspection; for the technical standards and compliance forms, consult the California Energy Commission resources and the Title 24 standards[2]. Where the city retains local amendments or enforcement procedures, those are published by the City of Thousand Oaks Building & Safety office and in the local municipal code; fee schedules and exact penalty figures may be listed in municipal fee resolutions or the municipal code and are not specified on the general building pages cited here[1].

Applications & Forms

To obtain permits and submit energy compliance documentation:

  • Submit building permit applications and energy compliance forms through the City of Thousand Oaks permits page; specific form names and filing instructions are published on the city site[3].
  • Permit fees and plan-check fees are set by the city fee schedule or resolution (fee amounts not specified on the cited permit pages).
  • Inspection requests and timelines are managed by Building & Safety; request inspections per the city’s procedures.

How enforcement and appeals work

Enforcement is handled by the Community Development Department, Building & Safety. To report a suspected violation or request inspection, contact Building & Safety via the city contact pages; if an enforcement notice is issued the notice will state appeal rights and timelines. Where the city’s public pages do not list specific appeal time limits, view the notice or municipal code section cited in the notice for exact deadlines (not specified on the cited general pages)[1].

  • Contact Building & Safety for compliance questions and to schedule inspections.
  • File an appeal or request a review as described on the enforcement notice or municipal code.
