Underwriting guidelines

An insurer's internal rules for which homes it will write, which it will decline, and what conditions, limits or surcharges apply to the ones it accepts.

Also called: underwriting rules, underwriting manual, underwriting appetite, eligibility rules

Underwriting guidelines are the company's own rulebook for homeowners business. They set maximum roof and home ages, limits on prior claims, which wiring, plumbing and electrical panels are acceptable, coastal and wildfire exposure, rules for pools, trampolines and certain dog breeds, and dwelling limit ranges. Insurers rarely publish them in full, which is why a decline or a nonrenewal can feel arbitrary.

Guidelines differ by company, and that is the reason one insurer declines a home that another accepts. Say one carrier will not write asphalt roofs over 15 years old: a 17-year-old roof is declined there, while a competitor offers a policy with a roof payment schedule. Guidelines also change. A carrier that cuts its appetite in a hurricane state can start declining new business or nonrenewing existing policies that no longer meet the rules, usually with notice required by state law.

Rates and rules that affect price are filed with the regulator; many eligibility criteria stay internal. If an insurer declines you based on a credit-based score or claims report, federal law requires notice naming the agency so you can check the report for errors. Ask the agent which guideline triggered a decision and what fix would change it. The underwriting guide and roof age limits: when insurers won't cover an old roof cover the common triggers.
