About Local ADU Guide
Local ADU Guide is an independent research directory for homeowners comparing local ADU rules, preapproved plan sources, and provider research before they shortlist design or construction help.
What the site is for
ADU rules are local. A homeowner usually needs to confirm city rules first, then compare nearby designers, builders, engineers, permit agents, or preapproved-plan vendors. This site separates those two jobs: city pages focus on official rules, while county pages group provider research by verification status.
Independent
The directory is not a city website, contractor marketplace, or quote-routing service. Provider rows are research records unless the verification policy says otherwise.
Source-backed
Rule pages cite official city, county, or public-agency sources. Provider pages keep official vendors, pending records, and discovery leads visibly separated.
Conservative
Permit-contact rows are discovery leads only. Quote routing remains off until outreach, active license review, and provider consent are complete.
Expandable
The first coverage area is California ADU research, starting with Bay Area counties. The structure is designed to expand by region, county, city, and topic.
