Summary

Los Angeles requires a plumbing or fire sprinkler permit from the Department of Building and Safety before any plumbing, gas, rainwater, standpipe, or graywater piping work under LAMC § 94.103.1.1: covering everything from new fixture installs to sewer-line work. Routine repairs like fixing a leaky faucet are exempt, but where a permit is needed, fees start at $24 for issuance plus per-fixture charges under LAMC Table 103.4.

94.103.1.1. General. Except as otherwise provided in this Code, no person shall add, alter, construct, install, move, reconstruct, relocate, remove, repair or replace any plumbing, fire sprinkler, rainwater piping, standpipe, subsurface drainage piping, swimming pool piping, reclaimed water piping, underground fire protection piping, or graywater piping system unless a plumbing or fire sprinkler permit for it has been obtained from the Department.

Full Breakdown

1, so the permit trigger reaches essentially every fixture and line that code covers. 2 carves out routine maintenance: no permit is needed to repair or replace faucets, ball cocks, exposed fixture traps, shut-off valves, or a residential garbage disposal; to clear a stoppage or fix a leak that doesn't require removing fixtures or drainage piping; to work on a gas utility meter or the piping between the main and the meter; or to reset fixtures pulled only to repair a wall or floor. 4 sets the fee schedule LADBS charges: a $24 permit-issuing fee plus a $20 supplementary issuing fee, $23 to install each new plumbing fixture (toilets, sinks, tubs, and similar waste-discharging devices) or $10 to replace or remove one, $17 per water-treating or dispensing device connected to a potable water system, and $14 per fixture to replace water piping in a building. 0601 for cause.

Violations & Fines

Plumbing or gas work performed without the required permit is subject to LADBS enforcement action, including stop-work orders and mandatory inspection before finished work can be covered or connected to service. LAMC § 94.103.1.1.4 offers a narrow grace period: obtaining the permit by noon on the third business day the Department's office is open after work started avoids fines, imprisonment, or the investigation fee, but only within that window.

Frequently Asked Questions

Do I need a permit to replace a water heater in Los Angeles?
Only if the water heater is disconnected during the work. LAMC § 94.103.1.2.7 exempts repair of a gas-fired water heater from a permit only when it isn't disconnected; pulling and replacing the whole unit counts as a new installation and needs a plumbing permit under LAMC § 94.103.1.1, inspected by LADBS before it's placed into service.
What does a plumbing permit cost in Los Angeles?
LADBS charges a $24 permit-issuing fee plus a $20 supplementary issuing fee under LAMC Table 103.4, then per-item charges, $23 to install a new fixture like a sink or toilet, $10 to replace or remove one, and $17 for each water-treating device connected to the potable system. Total cost scales with the number of fixtures and lines on the job.
Can I fix a leaky faucet myself without a permit?
Yes. LAMC § 94.103.1.2.2 exempts repairing or replacing faucets, ball cocks, exposed fixture traps, shut-off valves, and residential garbage disposals from the permit requirement. The exemption stops there: replacing drainage piping or adding a fixture still needs a permit under LAMC § 94.103.1.1.
