New California Building Codes Effective January 1, 2023

The Martinez Building Inspection Division will switch from enforcing the 2019 California set of Codes to the 2022 editions adopted by the State. All construction projects submitted after that date must comply with the 2022 editions.

The complete list of California Codes can be found in the Martinez Municipal Code, Chapter 15.

Building Permits

The Building Department issues building permits to homeowners and licensed contractors to regulate construction within the City limits. We work closely with the Planning and Engineering Divisions to help maintain a small-town feeling while ensuring that modern-day building safety requirements are met.

All contractors must have a current business license before permits are issued. Apply/renew a business license online. For Expedited Service please call the number provided

For Building Code questions please contact the Building Plan Checker at or 925-372-3529

Based on the current edition of the International Building codes, building permits are issued during the following days and times.

  • Monday – Friday: 10:00 a.m. – 2:00 p.m.

These codes are followed not only to protect your health and safety, but that of your property investment as well. If improvements have been made to your home, evidence of a building permit and final inspection of the work is often necessary to obtain financing or sell your property. The Building Department is located at City Hall at 525 Henrietta Street, Martinez, CA 94553.

  • Over the past 20 or so years I have only visited this Building Department 2 or 3 times. As far as I recall these folks were always helpful and friendly. I cannot say anything negative about them at all. I do not believew I have ever visited there when it’s busy. If I recall correctly, every time I went there, I was first in line. That is not a complaint. Believe me 1st beats 45th by a long shot.
