Why Marin County Issues Violation Notices — and What They Expect From You
Whether you've lived in your home for decades or just closed on it last month, discovering unpermitted work — or receiving a violation notice — is a jarring experience. For new buyers especially, it's often a complete surprise: the work was done before you owned the property, and now it's your problem to resolve.
Marin County, like all Florida counties, holds the current property owner responsible for permit compliance — regardless of who did the work or when. That's not intuitive, but it's the law. And it's why real estate attorneys and inspectors always recommend a thorough permit history check before closing.
The silver lining: you have options. After-the-fact permits exist precisely for this situation. The county wants the work documented. If the work meets current code (or can be brought up to code), you can get it permitted retroactively. If it doesn't meet code, a licensed contractor can help you determine the most cost-effective path to compliance.
Either way, inaction is the worst choice. Let's look at what Marin County expects from you — and how to get ahead of this as fast as possible.
Your Marin County Violation Notice — Decoded
Your Marin County violation notice is the county's way of saying: work was done here without going through the proper permit process, and we need you to fix that. The county's building code — administered 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.
