Construction documents · California
A California review starts with the applicable Title 24 parts and the city or county amendments for the project. Keep that reference set together so code notes, schedules, and consultant drawings can be checked against the same requirements.

Prepare a useful review
Use this preparation list for Groundbook alongside the official permit checklist.

Supply relevant local amendment PDFs and the current intake checklist. Include written project conditions or prior review comments that the drawings must address.
Add the energy and CALGreen documents relevant to the project alongside architectural, structural, civil, and MEP PDFs. Ask reviewers to reconcile values and scope across the package.
Identify which files are being checked, which are references, and which revisions are superseded. Include reviewer comments and responses where they explain an unresolved decision.
Use the drawing-register templateFrom documents to decisions
Compare stated design information with the code and local references you supply. Verify scope, exceptions, and the source behind each potential issue.
Review code referencesLook for incomplete information and conflicting requirements before submission. Assign each verified finding to the responsible designer.
Prepare for submissionCheck relationships across drawings, schedules, specifications, and reports. Resolve the source conflict and carry the decision into the issued set.
Review the whole packageBefore you start
This page prepares the document and reference set for an AI-assisted review. The separate AB 253 guide explains that specific private-review pathway; Groundbook does not itself act as a private plans examiner or grant permit approval.
Supply the current drawing set and schedules, relevant specifications and reports, the applicable code and amendment PDFs, and the reviewing authority’s checklist. Identify the edition, project scope, and permit stage. Groundbook reviews the supplied evidence; do not assume every local requirement is already available.
No. Groundbook surfaces potential conflicts and omissions with links to source documents for professional verification. It does not issue permits, certify compliance, provide permit-expediting services, or replace the authority having jurisdiction.
