California, Glenn County Remodeler Permit Regulations and County Ordinances for Unincorporated Areas
Glenn County Building & Safety Division
The Glenn County Building & Safety Division, part of the Planning & Community Development Services Agency, acts as the Authority Having Jurisdiction (AHJ) for building permits and inspections within the county. They are currently accepting permit applications via email or in person, with applications, plans, and supporting documents to be sent to [email protected] for screening.
Unincorporated Areas
The Glenn County Building & Safety Division's requirements apply to properties within unincorporated areas of the county. It is crucial to contact the Planning Department ([email protected]) before submitting a building permit application to determine zoning regulations and any associated fees for your specific project.
Demolition Work During Remodels
A building permit is required for the demolition of any building or a portion thereof, including single-family dwellings, garages, and storage units. A Demolition Permit Package is available from the County of Glenn. Applicants must also complete a Demolition Permit Asbestos Notification Statement if required, which involves determining if an "Asbestos NESHAP Notification of Demolition and Renovation Form" needs to be filed with the state.
Converting Non-Living Spaces to Habitable Areas
Converting non-living spaces such as garages, attics, or unfinished basements into habitable living areas generally requires a building permit. This is because such conversions involve structural, electrical, and plumbing upgrades that must comply with current building codes and life safety standards.
- Garages: Converting a garage into living space requires a building permit. This includes any associated electrical, plumbing, or mechanical work. Plans illustrating the proposed work, including floor plans, window/door openings, and locations of safety devices, are necessary. Properties may also need to provide alternative off-street parking, as garage conversions reduce available parking.
- Attics: Remodeling an attic to create habitable space (e.g., a bedroom, office, or playroom) almost always requires a permit. This involves meeting specific building codes for safety and occupancy, such as minimum ceiling height (at least 7 feet for 50% of the space), minimum room dimensions (e.g., 70 sq. ft. with a 7-foot minimum in any direction), and adequate egress, typically including a code-compliant staircase and an egress window. Structural changes to the roof or load-bearing walls will also require permits and potentially structural engineering review.
- Unfinished Basements: Finishing an unfinished basement into living space generally requires a permit, similar to other major home remodel projects. Projects that typically trigger permit requirements include installing electrical outlets, framing and drywall, running plumbing, installing bathrooms or kitchenettes, and tying into the HVAC system.

California Remodeler Legislation, Codes, and Guidelines
California State Building Codes and Legislation for Remodelers and Residential Renovations
California's building codes are primarily governed by the California Building Standards Code, also known as Title 24 of the California Code of Regulations. This code is updated on a triennial cycle, with new editions typically taking effect on January 1st of the year following publication. The most recent edition is the 2025 California Building Standards Code, effective January 1, 2026, which replaces the 2022 edition.
1. Adopted State Statutes and Codes
California adopts and amends national model codes to create its own building standards. Title 24 includes various parts that cover different aspects of construction, such as:
- California Building Code (CBC), which incorporates the International Building Code (IBC) with California amendments.
- California Residential Code (CRC), which applies to one- and two-family dwellings.
- California Existing Building Code (CEBC), which addresses alterations and retrofits.
- California Green Building Standards Code (CALGreen), focusing on sustainability.
- California Energy Code, which applies to most significant renovations.
- California Plumbing, Mechanical, Electrical, and Fire Codes.
The International Existing Building Code (IEBC) is not directly adopted by name, but its principles are integrated into the California Existing Building Code.
2. Primary State Board or Agencies
The California Building Standards Commission (CBSC) is the primary state agency responsible for managing the development, adoption, approval, publication, and implementation of California's building codes. The CBSC operates under the California Department of General Services (DGS). Several other state agencies are involved in the code adoption process, including the Department of Public Health, the Office of Statewide Health Planning and Development, the Department of Housing and Community Development, the State Energy Resources Conservation and Development Commission (California Energy Commission), and the State Fire Marshal.
3. Classification of Remodels and Demolition Guidelines
California code generally distinguishes between "repairs" and "alterations" (renovations). Repairs typically involve fixing existing components without increasing energy consumption, while alterations involve changes to the building envelope or equipment, or changes in the use or occupancy of a space.
Cosmetic Remodels vs. Structural Alterations:
- Cosmetic remodels, such as kitchen and bathroom updates, interior improvements, and non-structural alterations, are generally considered alterations. The B-2 Residential Remodeling Contractor license, for instance, is designed for extensive remodeling work that does not permit major structural modifications.
- Structural alterations, such as converting attics or basements to habitable living spaces, changing walls, foundations, roofs, or load-bearing elements, typically require permits and are subject to more stringent code requirements. Converting an enclosed porch into a living space is considered an addition that must meet current code compliance.
The "50% Rule": A significant guideline is the "50% Rule," which states that if the cost of alterations or additions exceeds 50% of the building's value, the entire building must be brought up to current code standards, essentially treating it as new construction. This can trigger substantial upgrades, including fire and life safety requirements and energy efficiency standards.
Demolition Guidelines:
- Demolition is generally defined as the razing, removal, deconstruction, salvaging, or wrecking of a structure or its components.
- A demolition permit is typically required for the removal of an entire building or structure. However, demolition work associated with an addition or remodel may be covered under the permit for that project.
- Specific demolition procedures are outlined in regulations, including requirements for utility shut-offs, protection of workers and the public, and proper disposal of waste materials.
- Local jurisdictions may have supplemental regulations for demolition, including requirements related to environmental protection and historical preservation.
