When starting any construction or remodeling project in California, one of the first things homeowners need to address is building permits and compliance with the California Building Code. At JJ Construction and Design Inc. DBA: Forward Design Build, we prioritize educating our clients so they can make informed decisions about their homes and properties. As a California Licensed Contractor, we’re here to break down the key updates and permitting essentials for 2025.

Whether you're remodeling a kitchen, adding an ADU (Accessory Dwelling Unit), or starting a full-scale home renovation, a building permit is legally required for most structural, plumbing, electrical, and mechanical changes. The purpose of these permits is to ensure that all work complies with local safety standards and California Building Code regulations.

2025 California Building Code Updates – What’s New?

The California Building Standards Commission updates the California Building Code (CBC) every three years. The 2025 edition includes notable changes homeowners should be aware of:

1. Energy Efficiency

California continues to lead in sustainable building. New codes require even higher standards for energy-efficient systems, including HVAC upgrades and solar readiness for new constructions.

2. Seismic Safety Enhancements

Given California’s earthquake risks, new structural guidelines aim to improve the seismic resilience of homes and additions.

3. ADU Regulations

Accessory Dwelling Units remain a hot topic. The 2025 update includes streamlined permitting processes and eased zoning restrictions, making it easier for homeowners to build on their property.

4. Electric-Only Mandates (in some jurisdictions)

Several counties are pushing for all-electric homes. That means gas stoves and heaters may be phased out in some areas. Check your local city or county’s regulations.

What Permits Do You Need?

Depending on the scope of your project, you may need one or more of the following:

Building Permit
Electrical Permit
Plumbing Permit
Mechanical Permit
Grading Permit (for extensive site work)

Local cities and counties—like San Leandro, Oakland, or Alameda—each have specific requirements. Working with a trusted Construction Company in California, like JJ Construction and Design Inc. DBA: Forward Design Build, ensures you're covered.
