Building Permits are required before you erect, construct, enlarge, alter, repair, move, improve, remove, convert or demolish any building or structure. See Section 106.2 of the California Building Code for further exemptions. The link below provides a summary of the exemptions. Exemption from the permit requirements shall not be deemed to grant authorization for any work to be done in any manner in violation of the provisions of any County code or ordinance. Please call us if you have any questions (925) 674-7200.
Some projects require approval either by the County Planning Division or City Planning Department and other agencies before the Building Inspection Division can proceed with the plan review. Then depending on the scope of the project, it may take anywhere from one day to several weeks depending on the amount of structural and non-structural review required.
Minor projects that are usually issued either that day or the next day are:
• Minor in-kind repairs due to damage caused by fire, termites, or deterioration • Minor interior alterations with no structural work • Plumbing, mechanical, or electrical repairs, change-outs, or alterations • Mobile homes
Major Projects that may take up to several weeks to review are:
• Changes in building use or occupancy • Major additions (greater than 50 percent of the existing structure) • Major structural work (seismic upgrades, major repairs, etc.) • Major tenant improvements • New residences in subdivisions with established master plans • Compliance with Title 24 energy documentation requirements
