In East Los Angeles, permits come from LA County Public Works, not a city hall. The county's permit list names new buildings, grading and ADA striping, but it doesn't name parking lot paving, so we won't know whether your lot needs a permit until we ask. I check with the county's East Los Angeles Building and Safety office before we set a date. If you need a permit, we take care of it and the inspections.
Two more checks belong with the county before work starts. Its stormwater design standards call for planted islands and landscaped areas in parking lots, which can decide where yours go. A state accessibility rule applies to some lots and counts the required accessible spaces for each lot on a site separately. The office takes calls at (323) 881-7030, Monday through Thursday 7 AM to 4:30 PM and Friday 7 AM to 3:30 PM.
We're based in East Los Angeles and work in the cities around it, like Montebello and Downey, plus plenty of others nearby. Most of those cities run their own permit counters, so the office depends on your address. A lot of the lots we pour around here sit behind shops and small apartment buildings, where delivery trucks and customer cars share a tight slab.
