You're Not Alone. Thousands of Maryland 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 Montgomery 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 Montgomery County, all structural, electrical, plumbing, and HVAC work requires a permit issued by the Department of Permitting Services.
Common Violations in Montgomery County
- Unpermitted additions and room expansions
- Unpermitted decks and porches
- Unpermitted basement finishing
- Unpermitted electrical work
- Unpermitted plumbing modifications
- Unpermitted HVAC installations
- Building without required structural engineering stamps
- Setback violations

- Work performed without licensed contractor
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
Montgomery County allows retroactive permits for unpermitted work, but the process is expensive and risky. Homeowners face stop-work orders and must pay for inspections that tear into completed work to verify code compliance. According to industry sources, retrofitting permits costs 300-500% more than obtaining them before construction. The process requires submitting the same documentation as a standard permit (site plans, architectural drawings, structural engineering stamps) plus additional inspections to verify existing work meets code. If work is concealed, inspectors may require demolition to verify compliance. Violations are addressed through a notice of violation with corrective actions and deadlines. If the owner does not respond or correct the violation, DPS may issue civil citations and pursue legal action including court abatement orders.
