Los Angeles contractor permits, business tax and city conduct rules

Los Angeles is large, and the City of Los Angeles is only part of it. Santa Monica, Beverly Hills, Glendale, Pasadena and Long Beach have their own rules, and unincorporated areas follow the county. This page covers the city proper, drawing on what Los Angeles city departments published through October 2026. Read it as general information rather than legal advice, and verify with the agencies before you act.

The state licenses contractors, the city taxes and permits them

California's Contractors State License Board issues contractor licenses. The state rules, including the $1,000 job threshold and the $25,000 bond, are on our California page and in the California contractor licenses guide. The City of Los Angeles layers three things on top: a business tax registration, building and trade permits from the Department of Building and Safety (LADBS), and local conduct rules such as noise hours and leaf blower limits. A CSLB license does not replace any of them.

The Business Tax Registration Certificate reaches businesses based outside the city

The Office of Finance says that if you are self-employed, your business address is outside the City of Los Angeles and you work within the city for seven days or more in a calendar year, you are an eligible business and must apply for a Business Tax Registration Certificate. A plumber based in Burbank who takes jobs in Sherman Oaks is therefore on the hook. The city defines business broadly: any activity conducted for gain, benefit or advantage.

The small business exemption can make this cheaper than it sounds. A business qualifies if its tax measures do not exceed $100,000 for the previous year in taxable and nontaxable gross receipts, counted worldwide. No tax is due from a small business that files a timely renewal. A business that renews late under LAMC section 21.29 is delinquent, loses the exemption and must pay the tax that would otherwise be due. Register first, then put the renewal on the calendar.

If you are over the threshold, contractors have their own class. The Office of Finance's rate table, revised August 2025, lists a contractor minimum tax of $153.00 on gross receipts up to $60,000, then $1.01 per $1,000 above that. A second class, for out-of-city contractor receipts, adds $2.55 per $1,000. Other service businesses fall into other classes, so read the table for your trade rather than assuming the contractor rate.

LADBS permits and what it checks about your license

LADBS states that a permit is required for any private property construction, alteration or repair work on buildings within the city. That is the default, and exceptions are narrow. Its guidance for agents says that when you obtain a permit as the agent of a contractor, you must make sure the contractor has an active license and is insured, and it points to a separate Notice to Contractors on insurance and license requirements. An agent acting for an owner also needs a letter of authorization, notarized or signed with a copy of the owner's ID, plus a completed Owner-Builder Declaration from the owner.

Owner-builder permits matter to you even if you never pull one. LADBS gives owners a notice, under state Assembly Bill 2335, warning that an owner-builder may be held liable for injuries to unlicensed workers and that a homeowner's insurance policy may not cover them. It is a useful point when a homeowner asks you to "just pull the permit under my name." You can find general license guidance in our contractor license guide.

Gas-powered leaf blowers are restricted near homes

This is the rule that catches landscapers and lawn crews. The ordinance that added subsection (c) to section 112.04 of the Los Angeles Municipal Code says no gas-powered blower may be used within 500 feet of a residence at any time. The exception is a leaf vacuum device that operates at a sound level of 45 dB(A) or less. The text also says both the user and the employer of the user are subject to the ordinance's penalty provisions, so the company owner is exposed, not just the worker.

In 2024 a City Council motion, Council File 24-0055, asked for a report on better enforcement of this restriction, and community groups wrote that they had seen illegal use. If your crew works in a dense neighborhood, switch to battery equipment before a neighbor calls it in. Our lawn care start-up guide covers equipment in general.

Construction hours and equipment noise

A City Planning environmental report summarizes section 41.40 of the Municipal Code this way: no construction or repair work between 9 p.m. and 7 a.m., and within 500 feet of occupied land, no work before 8 a.m. or after 6 p.m. on Saturdays or federal holidays, or at any time on Sundays. An individual homeowner working on their own single-family dwelling is excluded, and the city may grant waivers. The same report quotes section 112.05, which prohibits powered equipment or hand tools producing more than 75 dBA at 50 feet unless compliance is technically infeasible. Because the report is a planning document from 2010, confirm the current wording of both sections in the Municipal Code before scheduling around it.

The city minimum wage is higher than the state's

The Office of Wage Standards notified employers on January 30, 2026 that the minimum wage rises $0.55 to $18.42 an hour on July 1, 2026, tied to the Consumer Price Index for the Los Angeles area. It applies to employees who perform at least two hours of work within the city boundaries for an employer, which includes crews that live in other cities. Employers must post the city's notice at any workplace or job site where an employee works, in English, Spanish and the other languages named in LAMC section 188.03. For a roving crew, that means the notice goes with the truck or the job-site packet.

Calling before you dig

Southern California's notification center is DigAlert. California Government Code section 4216.2 sets the notice: a ticket at least two working days ahead (the day you call does not count), with a 14-calendar-day ceiling on how early you may call before the dig. DigAlert's California law page says digging without a ticket can bring fines up to $50,000 plus the repair cost of any damaged underground facility. Tickets are free, through DigAlert Direct, by calling 811 or by calling 800-422-4133. DigAlert also notes that the person doing the work must have the ticket in their own name, so a contractor cannot lean on the homeowner's call. This is a state rule run by a regional center, not a city rule, but it applies to a sprinkler install in Encino the same way. Emergencies are excused from advance notice, though not from liability for damage.

Rain falls in winter and the dry season runs long

Downtown Los Angeles in NOAA's 1991 to 2020 normals show 14.25 inches of precipitation a year, most of it from November to March. January averages 3.29 inches and February 3.64, while July is 0.02 and August is 0.00. Average highs run from 67.4 degrees in December to 84.0 in August. That pattern gives exterior work a long season, with a rush on roof, gutter and drainage calls when the storms arrive. The state's seasons are covered on our California page.

What this means for your website, phones and email

List your CSLB number, your city tax registration and your service areas on your website. California requires consent from all parties to record a call, so an AI receptionist or recorded line should say so up front, as explained in our recording guide.
