Los Angeles & Long Beach Dock & Door Repair Service Area
Call (385) 325-7138 about dock and commercial door work at facilities across Los Angeles County and Orange County — Los Angeles, Long Beach and the industrial cities around them.

Call to describe the problem—if the door is stuck open or the dock is down, say so first.

Pages for specific cities
- Vernon — an all-industrial city with its own Building Division, served by LA County Fire since 2020.
- City of Industry — County Building & Safety works at City Hall and uses a specified BSOP permit portal.
- Santa Fe Springs — has its own building division and fire department.
- Carson and Rancho Dominguez — neighboring addresses can use different building and fire offices.
Why the city matters
Los Angeles County has 88 cities and about 140 unincorporated areas (LA County). For dock and door work, two things change with the address:
- Who issues permits. The City of Los Angeles uses LADBS; Long Beach uses its Community Development department. LA County Public Works serves unincorporated areas. Carson and Santa Fe Springs direct applicants to their city building divisions; City of Industry lists County Building & Safety at City Hall and its BSOP portal. Start with the office for the street address (LA County permit locator).
- Who is the fire authority. This matters for fire doors. The City of Los Angeles has LAFD, whose Chief's Regulation 4 sets yearly fire-door tests (LAFD). LA County Fire serves all unincorporated areas plus 60 member cities (LA County Fire). Some cities have their own fire departments.
The provider and the right office confirm what applies to your job.

City of Los Angeles
The City of Los Angeles covers far more industrial ground than most people expect: the downtown and Alameda Street corridor, Boyle Heights, South LA, the harbor neighborhoods of Wilmington, San Pedro and Harbor Gateway, and the Valley's Sun Valley, Pacoima, Sylmar, Chatsworth and Van Nuys. All of it uses LADBS for permits and LAFD for fire. LADBS's fast Express Permit list has no item for commercial, overhead or rolling doors (LADBS). LAFD requires yearly fire-door tests by a certified tester. Santa Monica, Culver City and West Hollywood on the Westside are separate cities with their own offices.
Long Beach
Long Beach runs its own building and fire departments. The Long Beach Permit Center is at 411 W. Ocean Blvd, 2nd Floor, 562-570-7648, and permits cover "alterations, replacements, and repair work," with minor items possibly exempt at the Building Official's call (Long Beach). The Port of Los Angeles reports that it and the Port of Long Beach together account for about 31% of all containerized international waterborne trade in the U.S. (Port of Los Angeles). Signal Hill, surrounded by Long Beach, is its own city served by LA County Fire.
Commerce and the central industrial cities
Commerce says it has 1,800 businesses and "excellent freeway and rail access" (City of Commerce). It has its own Building & Safety office and is served by LA County Fire. So are Huntington Park, Bell, Bell Gardens, Maywood, Cudahy, South Gate and Lynwood. The Alameda Corridor rail line runs through or along Vernon, Huntington Park, South Gate and Lynwood (ACTA). See Vernon for its own page.
Compton and Rancho Dominguez
Compton has its own Building & Safety office and its own fire department. Rancho Dominguez, right next to it, is unincorporated — LA County Public Works handles permits and LA County Fire handles fire. Two buildings a few blocks apart can have different offices, so give the exact address. Rancho Dominguez is covered with Carson on the Carson page.
Torrance
Torrance runs its own Building & Safety office and its own fire department, which does fire plan checks. It's not on LA County Fire's member list and not a County contract city. For fire doors, ask the Torrance Fire Department what it expects.
South Bay
Gardena, Hawthorne and El Segundo run their own building offices. In Lawndale and Lomita, start with the city office to confirm the current permit route and any County plan review. Gardena, Hawthorne, Lawndale and Lomita are LA County Fire cities. El Segundo has its own fire department.
Gateway Cities
The southeast county mixes offices and review arrangements. Start with each city's building counter; La Mirada, for example, handles permit issuance through its Building & Safety Division even though County staff can review plans (La Mirada). Most are LA County Fire cities, but Downey and Montebello have their own fire departments. Santa Fe Springs has its own building and fire departments.
San Gabriel Valley
City of Industry uses County Building & Safety at City Hall with BSOP for permit applications. LA County Public Works handles unincorporated Rowland Heights and Hacienda Heights. For Irwindale and the other named cities, start with that city's building office and confirm the permit route. Most are LA County Fire cities. West Covina, Pasadena, Arcadia and Monrovia aren't on the County's member list, so ask those cities.
Pomona Valley
Pomona, Diamond Bar, Claremont, La Verne and San Dimas sit next to the San Bernardino County line. Calls from here are reviewed case by case — give the address. Pomona, Diamond Bar, Claremont and San Dimas are LA County Fire cities. Facilities over the line in Chino, Montclair or Ontario use the Ontario hub.
San Fernando Valley, Burbank and Glendale
Burbank and Glendale each have their own building and fire departments. San Fernando is its own city. The rest of the Valley — Sun Valley, Pacoima, Sylmar, Chatsworth, Van Nuys — is the City of Los Angeles, with LADBS and LAFD.
Santa Clarita Valley
Santa Clarita, including Valencia, has its own Building & Safety office and is an LA County Fire city. Castaic is unincorporated, so the County handles permits.
Orange County
The federal metro area is Los Angeles County plus Orange County (OMB Bulletin 23-01). Orange County has its own offices, separate from anything in Los Angeles County. Each city issues its own permits, and unincorporated areas go through OC Development Services. North and central Orange County facilities can call; south Orange County is reviewed case by case.
Edges
The Antelope Valley (Lancaster and Palmdale, both LA County Fire cities) and south Orange County are farther out, so calls from there are reviewed case by case. San Bernardino and Riverside county facilities use the Ontario hub. Ventura County isn't covered here.
