Home inspections in Costa Mesa, CA

Much of Costa Mesa was built in the years after World War II, with large numbers of 1950s and 1960s ranch homes. Many have been remodeled or expanded, and ADUs are increasingly common.

Postwar ranch homes are simple, sturdy and easy to update, which is why so many have been. The inspection question is often how well the updates were done. Partial repipes, additions with their own subpanels and converted garages all show up.

California’s ADU laws have made backyard units common. If one is present, confirm its permit status and whether it has its own utilities.
