APPROVED POLICIES
TEMPORARY CERTIFICATE OF OCCUPANCY
☒ New ☐ Amendment ☐ Provisional | Effective Date: March 15, 2022 | Sunset Date:
Policy Statement: A Temporary Certificate of Occupancy (TCO) issued or extended for an active commercial building permit will remain valid for 60-days.
Policy Details:
A TCO enables occupancy or partial occupancy of an area and/or floors prior to the completion of the entire building. A TCO may be granted for a reasonable timeframe if the Chief Building Official (CBO) finds that no substantial hazard will result from such occupancy. All TCOs issued or extended will remain valid for 60 days.
Types of temporary occupancy can include stocking only, stocking and/or employee training, portion /phase of a building project to be open to the public and/or employee occupancy. Each TCO request is evaluated on a case-by-case basis.
At the direction of the CBO, the senior inspector, permit services manager, or designee will begin the TCO application process and verify all departmental sign offs are complete; revision fees paid; and outstanding agency sign offs are verified. Fees should be invoiced in Accela and verify payment is complete.
For TCO extensions, the start date will begin once approved
Policy Author: Roxanna Recinos-Serna, Chief Building Official Date Submitted: March 15, 2022
Date Revised:
Brief description of why this policy is needed: The building code authorizes the building official with issuing a TCO before the completion of the entire work covered by the permit. TCOs are only valid for 60 days which would allow time for completing the project. Additionally, to demonstrate a high level of customer service and flexibility, a TCO extension fee will not be assessed for permits that are ready for all final inspections.

PROCEDURES FOR THE APPROVAL OF THE INSTALLATION AND USE OF ELECTRICAL EQUIPMENT
☒ New ☐ Amendment ☐ Provisional | Effective Date: July 25, 2023 | Sunset Date:
Policy Statement: This policy is intended to ensure reasonable and practical safeguarding of people and property per the California Electrical Code, Article 90.1 (CEC) and conformity of electrical equipment to nationally recognized safety standards in harmony with the CEC.
Policy Details:
The installation and use of equipment required or permitted by the CEC shall be acceptable only if approved by the Chief Building Official or designee (CEC Section 110.2). In judging the acceptability of the equipment, the Building Division uses the considerations set forth in CEC Section 110.3. Equipment evaluated by nationally recognized testing laboratories provides a basis for approval by the Building Division (CEC Section 90.7).
Terms used in this policy are defined in Article 100 of the CEC.
Policy Criteria:
I. Listing and Labeling of Electrical Equipment
All electrical equipment shall be listed by a nationally recognized testing laboratory (NRTL) and labeled with the certification mark of that laboratory. All equipment shall be installed and used in accordance with any instructions included in the listing (CEC Section 110.3(b)).
The listing shall be in accordance with the applicable nationally recognized safety standard for the equipment that is in harmony with the CEC. The safety standard shall be identified within the NRTL’s certification directory.
The standard used for listing shall be covered by the scope of either the OSHA recognition per 29 CFR 1910.7 or the ANSI accreditation for the product certification body, and approved by the Chief Building Official.
ANSI link: Certificate Program Accreditation Overview (ansi.org)
Manufacturer’s self-certification of any equipment shall not be used as a basis for approval.
Exception 1: Field Modification of Listed and Labeled Electrical Equipment:
The acceptability of field modifications to listed and labeled electrical equipment shall be determined by the Chief Building Official. The Chief Building Official shall consider the effect of the modification on the integrity of the equipment. The Chief Building Official has the authority to require a Field Evaluation in accordance with Exception 2, or a Field Inspection by the nationally recognized testing laboratory that listed the equipment at no cost to the jurisdiction. A documented report shall be provided to the Chief Building Official stating that the modified equipment continues to comply with the listing requirements.
Exception 2: Non-Listed Electrical Equipment:
If installed or relocated equipment is not listed and labeled, the equipment shall either be replaced with listed and labeled equipment, or the Chief Building Official may make an evaluation on the acceptability of the equipment in accordance with CEC Section 110.3(a).
The Chief Building Official has the authority to require a Field Evaluation by a third party field evaluation body (FEB) approved by the Chief Building Official in accordance with NFPA 790 at no cost to the jurisdiction. Accreditation of a FEB by International Accreditation Services (IAS) in accordance with AC 354 (www.iasonline.org) is a method to demonstrate that the FEB meets the criteria of NFPA 790. Field evaluations are only to be performed within the scope of the FEB’s accreditation.
The Field Evaluation by the third party shall be performed in accordance with NFPA 791, and a copy of the documented report shall be provided to the Chief Building Official prior to final inspection. When the initial report notes items require further corrections, the FEB shall confirm such corrections have been made and they meet compliance with all the regulations. The final report shall be returned to the Chief Building Official prior to final inspection.
II. Reciprocal Approval of Field Tested Equipment Among Regional Jurisdictions
Equipment evaluated by a third party field evaluation organization that is relocated to another location is subject to the prior approval of the Chief Building Official, provided the installation and use are substantially the same and the field evaluation report is made available. The Chief Building Official has the authority to require a Field Evaluation in accordance with Exception 2.

AB 130: Major Changes to Residential Building Standards Freeze
Assembly Bill 130 (AB 130), signed into law on June 30, 2025, imposes a temporary freeze on new residential building standards from October 1, 2025, to June 1, 2031. This provision applies to the adoption of new State and local residential codes for six years. Despite this freeze, the 2025 California Building Standards Code will still take effect starting January 1, 2026, as it was adopted prior to AB 130. In effect, the updates in the 2025 Residential Code will still apply statewide for residential construction projects applied for starting in 2026, unless exempted per AB 130.
Nonresidential projects (commercial, industrial, mixed-use) however, will not be impacted by AB 130. New applications applied for starting January 1, 2026, will be under the 2025 CA Codes.
Model Home Compliance Provision
Production-style home construction will allow a builder to use the same building codes that were in effect when the Model Homes were approved for up to 10 years or when the project is complete, whichever comes first.
Footnotes:
1 Complete submittal: Permit application will be deemed complete by Building Staff. This includes a complete application, drawings and supportive documents. Reference our handout for more information.
- Currently Approved Master Plans
Approved Master Plans under previous Code (2022 Code Standards) can be utilized to continue submitting Production Permits under that Code, until the Tract specific to that Master Plan is built out.
- These Master Plans can be reused on a separate or new Tract submitted after January 1, 2026, provided site specific conditions are met for the soils condition, a geotechnical report and testing is provided for the new Tract.
Builder will not be required to update the design to comply with the newest Codes, unless one of the following occurs first:
- 10 years have passed since the original approval of the design, in this case Approved Master Plan.
- The Model Home Design (e.g., the Approved Master Plan), is “substantially changed”.
“Substantial Changes” are subject to the Chief Building Official and will be reviewed on a case-by-case basis. If the Model Home Design is determined to have changes deemed substantial, the code edition will be reviewed under the code in effect of the plan revision.
- New Master Plan Submittals & Revisions
Master Plans submitted after January 1, 2026, for new specified area Tracts will be subject to the 2025 Code Standards, and all Model Home and Production Home Permits will follow this cycle.
Any Master Plan Revisions that are considered “Substantial Changes” will be required to be submitted as a whole new Master Plan Submittal subject to the 2025 Code Standards.
