A Gateway City That Permits Through the County

Cerritos adopted the Los Angeles County Building Code as its own building code by ordinance, so plan review and inspection follow the County rules rather than a separate city code. Owners are often surprised by that, and it is the kind of thing that costs a week if a contractor assumes otherwise and submits to the wrong place.

Roughly three quarters of occupied homes here are owner occupied, so most jobs are single family: a rear deck over a patio, an entry stair, a balcony that has begun letting water into the wall behind it. Cerritos is one of the Gateway Cities of southeast Los Angeles County, on flat ground, so failures here are about slope and drainage rather than hillside runoff.

Flat ground failures follow a pattern. The surface was built close to level, water sits instead of running, and the standing water finds the one termination that was never detailed properly. Give it a few seasons and the sheathing under that spot is soft while the rest of the deck reads fine. Owners often describe it as sudden. It was not.

Because owner occupancy is high, most people here are paying for a repair they intend to live with for a long time. Tearing off and correcting the slope costs more on day one than another coat, and it is the only version still working in ten years.

We also fabricate and set stairs, so where an entry stair or a rear stair has gone past repair, replacing it in iron or precast is on the table rather than patching it for another year.

Pulling a Permit in Cerritos

Permits run through the City of Cerritos Department of Community Development, where you upload plans on the city's own submittal form or apply at the Building and Safety counter. Because Cerritos adopted the County building code, plan review and inspection follow County rules. We handle that submittal and the inspection so nothing stalls on a filing technicality.

Waterproofing in Cerritos: Your Questions

Why does Cerritos permit through the County?

The city adopted the Los Angeles County Building Code as its own by ordinance, so plan review and inspection follow County rules and permits are issued by the City of Cerritos Building and Safety Division, with applications filed online through the city's permit portal at permits.cerritos.gov

My deck looks fine but there is a stain inside. What is happening?

On flat ground the water usually sits rather than runs, then finds one bad termination and travels along the framing. The visible damage shows up well away from the actual entry point.

Do you replace stairs, not just coat them?

Yes. We fabricate custom iron and precast staircases as well as waterproof them, so when an entry stair is past repair we can set a new one rather than sell you another patch.
