La Mirada contracts its building services to LA County, so permits run through the County.
La Mirada contracts with the County of Los Angeles for its Building and Safety services, engineering included. Worth knowing up front, because a contractor expecting a city counter is filing in the wrong place, and that is time nobody planned for.
The city sits on the border between Los Angeles and Orange counties, with Santa Fe Springs to the west and Cerritos to the southwest, and the unincorporated areas of East Whittier and South Whittier to the north. There are 15,457 housing units here, 97.7 percent occupied, and 77.1 percent of the occupied ones are owner held.
That ownership rate makes this mostly homeowner work: rear decks over patios, entry stairs, and balconies that have started letting water into the wall below them. These are also properties people stay in, which changes the conversation. A repair that lasts is worth more than a repair that looks finished.
On flat inland lots the deck itself has to create all of its own fall, and most of the failures we see here start when it loses that. The surface settles slightly, or a previous repair filled the low spot, and now water sits where it used to run. Every crack under that puddle stays wet for days after the storm passes.
Under a leaking balcony the pattern is consistent: dark plywood spreading from the wall junction, fasteners in the ledger rusted, and the sill of the door soft at both ends. We cut back to sound material, rebuild the flashing and the fall, then put the system down over something worth coating.

With the County. La Mirada contracts with the County of Los Angeles for Building and Safety services, engineering included, so there is no city plan check counter to walk into. We prepare and submit through the County process and meet the County inspector on site.
The city's building page cites the California Building Code with the Los Angeles County amendment layered on top. Editions get updated, so we confirm the currently adopted version with the County before a package goes in rather than working from last year's information.
Something took the fall out. Usually a previous patch built the low area up, or the structure has settled slightly. Either way water now sits over the seams instead of running off them, and correcting the slope is the repair, not a new topcoat.
A professionally installed waterproofing system typically lasts many years. Capital Deck & Stair backs most projects with an 8-year warranty on workmanship, and proper maintenance can extend the life well beyond that.
Cost depends on the surface size, condition, and the coating system required. We provide a clear, itemized quote after a free on-site inspection, with no obligation and no pressure.
Most residential decks, balconies, and stairs take about a week from start to finish, depending on prep, repairs, and weather. We give you a firm timeline before work begins.
