Seventeen free planning tools for the questions that come up before drawings start — Title 24 requirements, ADU feasibility, setbacks, plan check risk, permit fees and drafting scope.
Every tool uses Bay Area figures and California code thresholds, and runs entirely in your browser — nothing is submitted and no email is required.
Answer a few questions about your project and find out whether California requires a CF1R energy report.
Open Tool →Find your California climate zone by city and see what it changes about your energy requirements.
