Fullerton homes and water damage
Downtown and Raymond Hills have 1920s–1940s homes. Sunny Hills and Golden Hills have mid-century homes on hillside lots. Many homes near downtown and Cal State Fullerton are older houses divided into rentals, with added bathrooms and aging water heaters. Tenants change each year, so slow leaks under sinks and behind showers can run for months before anyone reports them. Hillside homes in Sunny Hills and Golden Hills have sloped lots with drainage challenges, and mid-century homes there often have original copper plumbing under the slab.

Fullerton questions
Do I need a permit for repairs in Fullerton?
Cleanup and drying don't. Structural, plumbing and electrical repairs need permits from the City of Fullerton Building and Safety division.
Is a slab leak covered by insurance in Fullerton?
Many policies cover the water damage and access costs from a sudden slab leak, but not the pipe repair itself. Report it quickly and keep photos and the plumber's findings.
