Why Permits Matter: The Three Real Consequences of Unpermitted Work
Skipping a required county permit introduces serious legal, financial, and safety liabilities for homeowners.
1. Homeowner Insurance
If a water heater that was replaced without a permit fails and causes property damage, your insurance company may deny the claim on the grounds that the work was performed without the required permit. This is a documented outcome in Maryland claims disputes and is not a theoretical risk.
2. Home Sale Complications
A home inspector who identifies an unpermitted water heater replacement, repiping project, or gas line modification will flag it in the inspection report. The buyer agent will request documentation of permitted work. If it does not exist, the seller is typically required to either retroactively permit the work or provide a price concession.
3. Safety
The permit and inspection process exists because the work matters. An improperly installed expansion tank, a water heater without a functioning T&P valve, or a gas line with an undetected leak are genuine safety issues. The inspection catches these before they become emergencies.
