California Building Standards Code (Title 24)

California's compilation of building regulations, published in parts covering building, residential, electrical, mechanical, plumbing, energy, historical and existing buildings, fire, green building, and accessibility standards. It is adopted statewide and may be amended by state agencies and, within limits, by local governments.

California Building Standards Commission (CBSC)

The state body that administers rulemaking for Title 24, reviews and approves proposed building standards submitted by state agencies, and publishes the code editions. It also hears appeals and may adopt emergency standards between cycles.

Occupancy Classification

Grouping of a building or portion of it by the character of its use, such as assembly, business, educational, factory, high-hazard, institutional, mercantile, residential, storage, or utility. The group sets allowable height and area, required construction type, and egress features.

Related: Construction Type (Type I–V), Certificate of Occupancy
Construction Type (Type I–V)

Classification based on the fire resistance of structural elements, running from Type I (most fire resistive, noncombustible) to Type V (wood frame). Combined with occupancy group, it fixes the allowable building height and floor area.

Related: Fire-Resistance Rating, Occupancy Classification
Certificate of Occupancy

A document issued by the building official after inspection, confirming that a new or altered building complies with approved plans and code and authorizing occupancy for a stated use. A change of use generally requires a new or amended certificate.

Accessible Route

A continuous, unobstructed path connecting accessible elements and spaces, including entries, corridors, ramps, and elevators. It must satisfy Chapter 11B criteria for clear width, slope, surface, changes in level, and maneuvering clearance.

Related: Chapter 11B, Path of Travel Obligation
Chapter 11B

The accessibility chapter of the California Building Code applying to public accommodations, commercial facilities, and publicly funded housing. It is frequently stricter than the federal ADA Standards, so the more restrictive provision governs where both apply.

Related: Accessible Route, Path of Travel Obligation
Path of Travel Obligation

California rule requiring that when alterations or additions exceed a valuation threshold, a proportionate share of construction cost, currently 20 percent of adjusted construction cost, be spent upgrading the accessible path of travel, restrooms, telephones, and drinking fountains serving the altered area.

Related: Accessible Route, Chapter 11B
Reasonable Accommodation

A change in rules, policies, practices, services, or building features needed to give a person with a disability an equal opportunity to use and enjoy a dwelling, required under fair housing law unless it imposes an undue financial and administrative burden.

Related: Adaptable Dwelling Unit, Chapter 11B
Adaptable Dwelling Unit

A housing unit built with features that can be added or adjusted later, such as grab bar reinforcement, adjustable counters, and accessible controls, so it can readily serve occupants with disabilities. Covered multifamily housing must include such units under fair housing design rules.

Seismic Design Category

A classification from A through F assigned to a structure based on site seismicity and the building's occupancy and risk. It determines which analysis procedures, detailing, bracing, and nonstructural requirements apply under the building code.

Alquist-Priolo Earthquake Fault Zoning Act

California law directing the state geologist to delineate earthquake fault zones and requiring geologic investigation and disclosure before most structures for human occupancy may be permitted within a designated zone.

Related: Liquefaction, Seismic Design Category
Soft-Story Retrofit

Strengthening of older wood-frame buildings whose ground floor is weak or open, typically by adding steel frames, shear walls, or bracing. Several California cities require it by ordinance for multi-unit residential buildings on seismic hazard maps.

Related: Lateral Force-Resisting System, Liquefaction
Liquefaction

Loss of soil strength when saturated, loose granular soils are strongly shaken and behave temporarily like a fluid, causing settlement, lateral spreading, and foundation failure. California maps seismic hazard zones where geotechnical investigation is triggered.

Related: Alquist-Priolo Earthquake Fault Zoning Act, Seismic Design Category
Lateral Force-Resisting System

The structural assembly, such as shear walls, braced frames, moment frames, and diaphragms, that carries earthquake and wind loads to the foundation. Its configuration, irregularities, and detailing govern the analysis method and limits permitted by code.

Means of Egress

A continuous, unobstructed path from any point in a building to a public way, composed of exit access, the exit, and exit discharge. Each component must meet requirements for capacity, number, arrangement, and protection.

Related: Exit Access Travel Distance, Fire-Resistance Rating
Fire-Resistance Rating

The period in hours or minutes that an assembly resists fire exposure, established by standardized testing or approved calculation. Ratings apply to structural members, walls, floors, shaft enclosures, and opening protectives.

Related: Construction Type (Type I–V), Means of Egress
Wildland-Urban Interface (WUI)

An area where structures meet or intermingle with wildland fuels. Chapter 7A imposes ignition-resistant construction, roofing, venting, deck, and exterior material requirements on buildings in mapped fire hazard severity zones.

Related: Defensible Space
Defensible Space

Required thinning and clearance of vegetation and combustible material in zones around a structure, reducing fire intensity and giving firefighters a safer place to work. It is enforced under state law and local ordinance in fire hazard areas.

Related: Wildland-Urban Interface (WUI)
Exit Access Travel Distance

The measured distance from the most remote point on a story to the nearest exit, limited by occupancy group and the presence of sprinklers. Excessive distance is a common plan review finding requiring added exits or reconfiguration.

Related: Means of Egress
CALGreen

The California Green Building Standards Code, Title 24 Part 11. It sets mandatory statewide requirements for site development, water and energy efficiency, materials, indoor environmental quality, and construction waste management, with optional reach tiers above the mandatory level.
