Coastal Orange County, and home to Leisure World, one of the first 55-plus communities in the country.
Seal Beach sits in the westernmost corner of Orange County, just across the county line from Long Beach. Coastal position means salt air working continuously on fasteners, flashing and the edges of a coating, which is the sort of damage that does not announce itself until a detail lets go.
The city is also home to Leisure World, opened in 1962 as one of the first age segregated communities in the United States for residents over 55. Community property of that kind comes with its own approval expectations alongside the city permit, and with residents who need access maintained throughout the work rather than a walkway closed for a fortnight. We plan for both.
