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 free Action Plan — is built to help you do.
Understanding Your Mariposa 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 Mariposa County, all structural, electrical, plumbing, and HVAC work requires a permit issued by the Mariposa County Building Department.
Common Violations in Mariposa County
- Homes, additions, decks, sheds, barns, and gazebos built without permits
- Conversions to habitable space without permits
- Grading done without permits
- Electrical, mechanical, and plumbing work done without permits
- Unpermitted remodels and room additions
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
Mariposa County requires property owners to retain a California Registered Design Professional (Licensed Architect or Registered Engineer) to serve as the Design Professional of Record for unpermitted structures. The Design Professional must conduct a project survey, prepare as-built drawings, and ensure all trade elements are brought up to applicable code. The owner must then contact the Building Department, pay all required fees and penalties, and start the proper permit application process. Following permit issuance, inspections will be made by the Building Department, other County Departments as required, and the Design Professional of Record. The Design Professional must submit phase inspection letters and a final letter of acceptance stating the building conforms to applicable codes. Once all requirements are satisfactorily completed, a certificate of completion or occupancy will be issued. Per Ordinance #1173 (adopted May 10, 2022) and Mariposa County Code Section 15.10.260, if a violation exists on a parcel, the Building Department cannot accept any permit application on that parcel unless the requested permit is to correct the violation.
