East Los Angeles goes through the county, so LA County Public Works issues the permit here, including its permit for the driveway approach, sidewalk, curb and gutter where your driveway meets the street. The county wants the contractor's license number and insurance, plus a letter of authorization when the owner isn't the applicant. Since we apply, you'd sign that letter for us. The county's East Los Angeles Building and Safety Office answers at (323) 881-7030.
We check with the right office before we set a date, and when your job needs a permit, we take care of it and the inspections that go with it. Next door it's a different office, because Montebello, Downey and most of the cities around us run their own permit counters.
On new construction or a rebuild of four units or less, the county's runoff rules ask for at least two listed measures. Porous concrete, which lets rain soak through, counts when it makes up at least half the site's paving. Around here we replace a lot of older, narrow driveways that run tight along the house, so getting water to the street is most of the planning.
