Santa Monica, California Remodeler Local Permit Ordinances and Codes
Santa Monica Municipal Permit Ordinances for Remodelers and Home Renovations
In Santa Monica, California, the Building and Safety Division of the City of Santa Monica acts as the Authority Having Jurisdiction (AHJ) for building permits and related renovations. The City utilizes an Electronic Plan Review (EPR) system for permit applications and document submittals.
Demolition Permits vs. Standard Building Permits
A building permit is required for any construction, alteration, demolition, or repair of a building or structure. A distinct demolition permit is specifically required when a structure is proposed for demolition, or when the scope of work meets the city's definition of demolition. Partial demolition involving the removal of structural elements, such as walls or roof sections, also necessitates a building permit, potentially requiring structural plans to show how the remaining structure will be supported. Certain minor demolitions, like removing small accessory structures built after 1978 and not in a historic district, may be exempt from a demolition permit, though utility disconnection and proper disposal are still required. Demolitions of structures over 40 years old may require a landmark review.
Converting Non-Living Spaces to Habitable Areas
Converting non-living spaces, such as basements or garages, into habitable areas requires a building permit. This is because such conversions are considered structural upgrades that must comply with building codes, zoning rules, and life safety standards. In Santa Monica, converting a garage into an Accessory Dwelling Unit (ADU) is a common route for creating additional living space. The existing garage must have a proper foundation and be convertible to habitable space meeting all building codes. Properties in the coastal zone may have additional review requirements for exterior modifications and may need a Coastal Development Permit in addition to regular building permits.
Fee Nuances and Inspection Stages
Permit fees in Santa Monica are typically calculated based on the estimated project valuation. For demolition projects, fees can range from $150 to $1,500. Building permit fees are generally a percentage of the project valuation, with a minimum fee for certain projects. Plan review fees are also applicable and are a percentage of the building permit fee. All construction activity authorized by a building permit requires inspection clearances at various stages of the project before final approval. Inspections for issued building permits can be scheduled online. Re-inspection fees may apply if an inspection fails.

Because Santa Monica is located within Los Angeles County, the following broader county regulations may also apply to your project:
California, Los Angeles County Remodeler Permit Regulations and County Ordinances for Unincorporated Areas
Los Angeles County Remodeling and Renovation Permit Requirements
In Los Angeles County, the Building and Safety Division acts as the Authority Having Jurisdiction (AHJ) for building permits. This division is responsible for ensuring that all construction and remodeling projects comply with state and local building codes for safety and structural integrity.
Unincorporated Areas
Properties located in unincorporated areas of Los Angeles County fall directly under the jurisdiction of the County's Building and Safety Division. Residents in these areas must obtain permits from the county for any work that requires them, similar to those in incorporated cities, but through the county's specific departments.
Demolition Work
Demolition work during a remodel often triggers the need for a permit. This is especially true if the demolition involves:
- Removing structural elements.
- Demolishing more than a minor portion of a building.
- Asbestos abatement, which requires specific procedures and permits.
It is crucial to consult with the Building and Safety Division before commencing any demolition to determine the exact permit requirements.
Converting Non-Living Spaces
Converting non-living spaces such as garages, attics, or unfinished basements into habitable living areas is considered a significant alteration and almost always requires a building permit. This process typically involves:
- Ensuring the space meets current building code requirements for egress, ventilation, insulation, and structural support.
- Obtaining permits for the change of occupancy and any associated construction, such as adding bathrooms, kitchens, or modifying electrical and plumbing systems.
The definition of "habitable space" generally refers to areas intended for sleeping, cooking, or living, and converting these areas necessitates a thorough review and approval process by the AHJ.

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:
- 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.
