Permit and code upgrade costs are excluded from virtually all home warranty contracts. This exclusion catches homeowners off guard and can add hundreds to thousands of dollars to a covered claim.
When a warranty company approves a repair or replacement, they pay for the work as it stood when originally installed. When local building code requires upgrades to meet current standards during that repair, the upgrade costs are on you.

Code requirements change over time. A home built in 1985 had its systems installed to 1985 code. When those systems are replaced in 2026, they must meet 2026 code — and the delta between 1985 and 2026 requirements can be substantial.
If you own a home built before 1990, budget for code upgrade costs on any major system replacement. The warranty covers the system replacement; you cover the code compliance.
When you receive a covered HVAC or system replacement, ask the contractor: “What permit and code-related costs are NOT covered by the warranty?” Get that answer before work starts.
Some warranty companies offer an optional “code upgrade” rider or add-on that covers some of these costs. Check if your company offers this.
The warranty company’s contractor is responsible for pulling permits for the work. If they complete work without a permit where one is required, that’s their liability issue, not yours — but it creates future problems when you sell the home.
Verify that your warranty company’s contractors pull permits for work that requires them (HVAC replacement, water heater replacement, significant electrical work).
