Get Your Free ReportThe Problem: Marin County Permit Delays Are Costing You Thousands
If you are planning a construction project in Marin County, the permitting process is one of the biggest risks to your budget and timeline. The average plan check review in Marin County takes between 3 and 6 months — and that assumes your plans pass on the first review. Most do not.
Homeowners and even experienced architects routinely submit plans with code conflicts, missing Title 24 calculations, zoning violations, or fire code gaps that only surface after the county reviewer flags them weeks later. Each correction cycle adds 4 to 8 weeks to the timeline. On a typical Marin County remodel or ADU project, that translates to $15,000 to $40,000 in carrying costs, delayed rental income, and extended construction financing.
The fundamental issue is that plan check reviewers in Marin County are overloaded. The county has seen a surge in ADU applications, remodel permits, and fire-rebuild projects. The Community Development Agency processes hundreds of applications each quarter, and staffing has not kept pace. Your plans sit in a queue, and when they finally get reviewed, a single missed detail sends you back to the end of the line.
This is the problem ConstruBay set out to solve with PlanPass.ai — our proprietary AI-powered permit analysis platform built specifically for Marin and Sonoma County projects. Licensed general contractor CSLB #1106798.
The Solution: PlanPass.ai Pre-Submission Analysis
PlanPass.ai is an AI analysis engine that reads your construction blueprints and cross-references them against the full matrix of applicable codes: California Building Code, Title 24 energy requirements, local Marin County amendments, fire code and WUI zone regulations, zoning ordinances, and Design Review Board guidelines.
The system flags every conflict, gap, and ambiguity before you spend a dollar on county filing fees. It identifies issues that even experienced plan checkers sometimes miss on the first pass — things like conflicting setback interpretations between the county zoning code and the community plan, or Title 24 compliance gaps in window-to-wall ratios that only become apparent when the full energy model is calculated.
ConstruBay developed PlanPass.ai because we were tired of seeing our clients lose months and thousands of dollars to preventable permit delays. As a licensed general contractor (CSLB #1106798) with over a decade of experience building in Marin and Sonoma Counties, we know exactly what the county plan checkers look for — and we trained our AI on that institutional knowledge.
