Expert Navigation of California ADU Regulations

Since California expanded ADU rights through legislation such as AB 68, SB 13, and AB 881, accessory dwelling units have become one of the most effective ways for homeowners to add housing and increase property value. Barcci Builders stays current with state and local regulations, helping homeowners navigate city-specific requirements while ensuring full compliance throughout the approval process.

Their team works closely with municipalities across the Bay Area, including Los Gatos, Saratoga, San Jose, Palo Alto, Cupertino, Campbell, and surrounding communities, providing expert guidance on zoning, setbacks, lot coverage, utility connections, and local design review requirements.

A Structured Design-Build Process

Barcci Builders follows a proven seven-step process designed to simplify ADU development and eliminate uncertainty for homeowners:

1. Free Feasibility Assessment
2. Custom Design & 3D Architectural Renderings
3. Permit Preparation & Submission
4. Permit Approval Management
5. Construction & Daily Progress Updates
6. Inspections & Certificate of Occupancy
7. Final Walkthrough & Move-In Ready Delivery

This structured approach allows clients to visualize their project before construction begins while maintaining transparency throughout the entire build.

Advanced Design Technology & Fixed Pricing

One of the company’s distinguishing features is its use of photorealistic 3D renderings. Before permits are submitted, homeowners can review floor plans, exterior elevations, interior layouts, and finish selections in detail. This design-first approach helps minimize revisions and ensures every project aligns with the homeowner’s vision.

After the design phase is finalized, Barcci Builders provides a fixed-price construction contract, giving clients confidence in their budget and eliminating unexpected cost overruns during construction.

Building ADUs That Create Long-Term Value

Whether creating a detached rental unit, converting an existing garage, or adding a Junior ADU within a primary residence, Barcci Builders focuses on delivering high-quality accessory dwelling units that enhance both lifestyle and investment potential. Their commitment to craftsmanship, transparency, local expertise, and customer service has made them one of the Bay Area’s trusted names in ADU construction.
