You're Not Alone. Thousands of California Homeowners Face This Every Year.
The first thing most homeowners feel when they get a code violation notice is shock. You've lived in your home for years. Maybe you bought it this way. Maybe someone told you the work was fine. Maybe you did it yourself and thought it was okay. Now there's an official government notice sitting on your kitchen table.
Then comes the confusion. The letter is written in bureaucratic language. It references statute numbers you've never heard of. It gives you a deadline, but you're not sure what exactly you're supposed to do by that deadline. Call who? Do what? What happens if you don't respond?
And underneath it all is fear. Fear that you could lose your home. Fear of liens, fines, or foreclosure. Fear that you'll spend thousands of dollars and still end up in the same position. Fear that you made a mistake you can't undo.
Here's the truth: in most cases, this is completely fixable. The key is acting quickly, understanding the county-specific process, and connecting with the right professionals. That's exactly what this page — and our $9.95 Action Plan — is built to help you do.
Understanding Your Marin County Violation Notice
A permit violation notice means the county has identified work on your property that was done without the required building permits. In Marin County, all structural, electrical, plumbing, and HVAC work requires a permit issued by the Building and Safety Division, Community Development Agency.
Common Violations in Marin County
- Unpermitted ADUs and JADUs
- Unpermitted room additions
- Unpermitted bathroom installations
- Garage conversions without permits
- Unpermitted electrical work
- Unpermitted plumbing work
- Window and door replacements without permits
- Expired or incomplete building permits
- Work not meeting current building codes
The 30-Day Myth
Many homeowners believe they have 30 days to "fix" the problem. The truth is more nuanced: you typically have 30 days to respond — meaning you need to initiate the permit process or contact the building department, not complete all the work. However, fines and penalties can begin accruing from the date of the notice. Acting in the first 48 hours is always better than waiting.

After-the-Fact Permit Process
Marin County allows property owners to obtain retroactive permits for unpermitted work. The process involves submitting a Part A Application and Submittal Checklist through the online portal with complete construction drawings showing the existing work. Plans must be prepared by a licensed design professional and include site plans, floor plans, elevations, and construction details. The county has an ADU Legalization Program (per AB2533) specifically for unpermitted ADUs and JADUs constructed before January 1, 2020, which provides a streamlined process. For general unpermitted work, applicants must bring the work up to current building codes regardless of when construction occurred. The Code Compliance Division investigates violations and works with property owners to resolve issues. Property owners may receive a Violation Letter outlining required corrections. If unpermitted work existed prior to current ownership and was not previously disclosed, some jurisdictions in Marin may waive permit fees and penalties, though permits are still required and work must be inspected and approved.

What Marin Homeowners Are Saying
“Unincorporated Marin County does not require resale reports, but most incorporated cities and towns in Marin County do require Point of Sale inspections that identify unpermitted work.”
— City of San Rafael RBR Program
“Waiting to legalize unpermitted work until sale means you will be subject to codes at the time of inspection, not the time of construction, potentially requiring costly upgrades to meet current standards.”
— Thomas Henthorne Real Estate

— Marin County Building and Safety
“Effective January 1, 2026, Marin County no longer accepts paper plan submittals - all plans must be submitted electronically through the online portal.”
