Demolition Permits vs. Standard Residential Building Permits

Demolition permits are required for the removal of all or part of an existing structure, as well as for interior remodels that involve the removal of existing construction materials. This includes full building demolitions and partial demolitions that involve removing structural elements like walls or roof sections. Structures built before 1978 may require an asbestos survey. Small accessory structures built after 1978 may be exempt, but it's crucial to verify with the Building Department.

Space Alterations: Converting Non-Living Spaces

Converting non-living spaces such as garages or basements into habitable areas, often referred to as Accessory Dwelling Units (ADUs), is permitted in Fontana, provided it meets local building codes and zoning laws. This process requires obtaining building, electrical, and plumbing permits. The existing structure must be converted to habitable space, including proper insulation, ventilation, and egress windows. State laws encourage ADU construction and may override some restrictive local zoning rules, such as additional setback requirements for existing structures being converted. Parking requirements may also be waived under certain conditions, such as proximity to public transit or if the garage provided parking for the main home. ADUs under 750 square feet may be exempt from impact fees.

Fee Nuances and Inspection Stages

Building permit fees in Fontana are determined by various city departments, including building inspection, electrical, plumbing, and planning services. Fees are calculated based on project valuation, square footage, construction type, and occupancy type, and are subject to periodic updates. An online processing fee of 2.5% is applied to invoices paid through the ACA portal via PayPal, effective October 1, 2025. The "Build Fontana" portal allows for online payment of fees. Specific fee schedules for planning cases, development impact fees, and ADU plan checks are available. Inspections can be scheduled through the "Build Fontana" portal.

This division is responsible for ensuring that all construction and renovation projects comply with state and local building codes, promoting public safety, health, and general welfare.

Properties located in unincorporated areas of San Bernardino County are subject to the county's building codes and permit requirements. These areas are not within the jurisdiction of any incorporated city, meaning the County Building and Safety Division directly oversees all building and safety regulations.

Permit requirements for demolition work during a remodel in San Bernardino County depend on the scope of the demolition. Generally, any demolition that involves the removal of structural elements, or a significant portion of a building, will require a permit. This often includes the demolition of walls, roofs, or entire structures. It's crucial to consult with the Building and Safety Division to determine if a permit is needed for your specific demolition plans, as improper demolition can pose safety hazards and lead to code violations.

Converting Non-Living Spaces

The following statewide building codes and regulations apply universally to all jurisdictions within California:

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:

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:

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.
