San Bernardino County Roofing Permit Requirements
In San Bernardino County, California, a building permit is generally required for re-roofing activities. The permit process ensures compliance with the California Building Codes and the San Bernardino County Development Code. This process includes verifying that no more than two layers of roofing material are present and that re-roofing over certain materials like slate, clay, cement, or asbestos tile, or water-soaked/deteriorated roofing is not permitted under a standard re-roof permit.
The County's Building and Safety Division, under the Land Use Services department, is responsible for enforcing building standards through a permit process. This process involves plan review, permit issuance, and inspections to ensure construction meets minimum code standards for public health, safety, and property.
For properties in unincorporated areas of San Bernardino County, the County's Building and Safety Division has jurisdiction. Permits can be obtained through local Building and Safety offices or via the EZ Online Permitting (EZOP) website.

California Roofing Legislation, Codes, and Guidelines
California State Roofing Codes and Legislation
Roofing projects in California are governed by the California Building Standards Code, which is Title 24 of the California Code of Regulations. This comprehensive set of standards is updated on a triennial cycle to address the state's unique environmental challenges, including wildfire risks, seismic activity, and energy efficiency goals.
The primary codes regulating roofing include:
- California Building Code (CBC): Found in Title 24, Part 2, this code provides structural, fire-safety, and material standards for commercial and multi-family residential buildings.
- California Residential Code (CRC): Found in Title 24, Part 2.5, this code contains specific requirements for one- and two-family dwellings, including standards for roof coverings, underlayment, and installation.
- California Energy Code: Found in Title 24, Part 6, this code mandates "cool roof" requirements for new construction and significant roof replacements (typically when more than 50% of the roof is replaced or recovered). These standards regulate solar reflectance, thermal emittance, and the Solar Reflectance Index (SRI) based on the building's climate zone.
While California adopts model codes as a base, it frequently amends them to meet state-specific needs, such as the Wildland-Urban Interface (WUI) requirements that mandate Class A fire-rated roofing materials in high-fire-hazard zones.
Primary State Agencies
The following agencies are responsible for setting and overseeing these standards:
- California Building Standards Commission (CBSC): This commission is responsible for the administration, adoption, and publication of the California Building Standards Code (Title 24).
- California Energy Commission (CEC): The CEC is responsible for developing and updating the Building Energy Efficiency Standards (Title 24, Part 6), which dictate the energy performance requirements for roofing materials.
- Contractors State License Board (CSLB): The CSLB regulates the licensing of roofing contractors in California, ensuring that those performing the work meet professional standards and adhere to state regulations.
