How to Start a Cleaning Business in California

California is one of the largest cleaning markets in the country and one of the most regulated. The good news is that no state-level cleaning license stands between you and your first job. The hard part — and the part most new operators underestimate — is everything California asks of you the moment you have one employee. Workers' compensation kicks in at one employee. The AB 5 ABC test makes 1099 cleaners almost impossible to defend. The AB 1978 janitorial registration program applies the moment you bid your first commercial account. This guide walks through what California actually requires for a cleaning business in 2026, in the order you will run into it.

1. Pick a business structure

For a one-to-three-person crew, the practical choice is between a sole proprietorship and an LLC. The sole prop is free, but California is not a forgiving liability environment, and an LLC separates a slip-and-fall claim at a client's house from your personal bank account.

If you go LLC, file Articles of Organization (Form LLC-1) with the California Secretary of State through BizFile Online. The filing fee is $70. Standard online turnaround in mid-2026 is roughly six business days; you can pay $350 for 24-hour expedited or $750 for same-day service.

The cost most California LLCs don't realize is waiting in year one: the $800 minimum franchise tax to the Franchise Tax Board. The first-year waiver from AB 85 expired after tax year 2023, so any LLC formed in 2024 or later owes the full $800, due by the 15th day of the 4th month after formation. If formation paperwork feels like the wrong place to spend your time, Northwest Registered Agent and a handful of other formation services will file the LLC-1 and act as your agent for service of process for a modest annual fee.

2. Register with the state

Before filing, run a name search in BizFile Online to confirm the name you want is available and not too close to an existing California entity. Articles of Organization for an LLC ask you to name your members or managers, your registered office, and your agent for service of process — which must be either a California-resident individual with a physical street address (no P.O. boxes) or a registered corporate agent under Corporations Code §1505.

California LLCs file a Statement of Information (Form LLC-12) within 90 days of formation and every two years after, for $20. It is easy to forget; missing it costs $250 in penalties and eventually triggers suspension by the FTB.

3. Get your EIN and a business bank account

Apply for a free Employer Identification Number directly at irs.gov. It takes about ten minutes and costs nothing. Skip any site that charges a fee for an EIN — there is no fee. Once you have the EIN and your stamped formation document from the Secretary of State, most banks will open a business checking account the same day. Keep all cleaning income and expenses in that account from day one, and pair it with QuickBooks or another set of books — the cleaner the records, the easier every subsequent step gets.

4. Business licenses and permits

California does not have a statewide cleaning-business license. The Contractors State License Board only licenses cleaning work that is part of a construction contract over $500 (such as post-construction cleanup under a D-63 limited specialty), so standard residential and commercial janitorial work doesn't need a CSLB license.

What you do need is a Business Tax Certificate or registration in every city you actually work in. The largest ones:

• Los Angeles — Business Tax Registration Certificate through the LA Office of Finance. New small businesses with under $100,000 in worldwide gross receipts may qualify for the Small Business Exemption, but you still have to register and file annually to claim it.
• San Francisco — Business Registration Certificate with the SF Treasurer & Tax Collector, due within 30 days of starting; renewal moved to the last day of February starting in 2026.
• San Diego — Business Tax Certificate from the City Treasurer, due within 15 days of starting.
• Sacramento — Business Operations Tax with the City of Sacramento. If you run the business from your home inside city limits, the BOT application also pulls in a Home Occupation Permit, which restricts on-site customer visits and on-street vehicle storage.

If you hold yourself out under a name other than your legal name (or your LLC's exact registered name), you also file a Fictitious Business Name statement with the county where your principal place of business sits.

5. Sales tax on cleaning services

This is the easiest section in California: cleaning services are not subject to California sales tax. The state taxes retail sales of tangible personal property, not services. CDTFA's published guidance and Annotation 360.0180 treat cleaning, including rug, carpet, and upholstery cleaning, as nontaxable services, and treat the cleaning business as the consumer of its own cleaning supplies — meaning you pay sales tax when you buy the supplies, but you do not collect sales tax on the cleaning itself. If you start reselling cleaning products to clients on the side, that's a different conversation and you would need a CDTFA seller's permit for the resale piece.

6. Insurance and bonding

Carry general liability before your first paying job. There is no California-mandated minimum, but commercial clients and property-management vendor portals almost always want to see $1M per occurrence / $2M aggregate on a Certificate of Insurance before they let you on site. Next Insurance is one of the easier paths for a small cleaning operator looking for a fast online quote on a janitorial GL policy; a broker can be worth it once you start carrying real commercial accounts.

Workers' compensation is the line where California stops being optional. Labor Code §3700 requires every employer with one or more employees — including part-time — to secure workers' comp. There is no small-employer exemption, and operating without coverage is a misdemeanor with a minimum $10,000 fine and additional state penalties.

If you employ janitorial workers to clean commercial premises, AB 1978 (the Property Service Workers Protection Act) adds three more obligations: register your business annually with the DIR / Division of Labor Standards Enforcement for $500, post a surety bond with the Labor Commissioner of at least $10,000, and put each covered worker through biennial in-person harassment-prevention training delivered by a DIR-qualified organization. Residential-only house cleaners are outside the AB 1978 regime.

7. Hiring and payroll

California's 2026 statewide minimum wage is $16.90/hour, with no carve-out for small employers. The City of Los Angeles minimum is $17.87/hour through mid-2026, and San Francisco runs $19.18/hour through June 30 and $19.61/hour from July 1. The applicable rate follows the location of the work, not the employer's address — a crew that cleans in three cities in a day gets three rates that day.

Withhold 1.3% State Disability Insurance from every paycheck — SDI has had no wage cap since 2024 — which funds both California's disability program and Paid Family Leave (up to 8 weeks of partial wage replacement, capped at $1,765/week in 2026). Provide at least 5 days or 40 hours of paid sick leave per year under SB 616. A modern payroll provider like Gusto handles SDI withholding, multi-jurisdiction wage calculations, and the new-hire reporting California requires within 20 days of an employee's start date.

Then there is the part of California that catches operators by surprise: the AB 5 ABC test. A worker is presumed to be your employee unless you can prove (A) they are free from your control, (B) they perform work outside the usual course of your business, and (C) they are engaged in an independently established trade. A cleaner cleaning for a cleaning company fails prong B before the conversation starts. There is a narrow business-to-business exemption in Lab. Code §2776 for a contractor that operates as a real, separately licensed business with its own clients, but the conditions are strict. Practically: hire cleaners as W-2 employees, and route classification questions through the hiring guide and legal services before signing anyone on as 1099.

8. Get your first clients

California cleaning markets cluster around the major metros, but they don't all behave the same. In suburban Los Angeles and San Diego, Nextdoor referrals and Google reviews drive most early residential bookings. In San Francisco and the South Bay, property managers and tech-company office vendors are the volume — long sales cycles, but bigger contracts. Sacramento sits somewhere in between, with a meaningful state-government and university market for commercial janitorial.

Wherever you start, set up a Google Business Profile the same week you incorporate. Ask every happy customer for a review within 48 hours of the job, when the impression is fresh. A tool like NiceJob automates the ask and routes responses; you can do the same thing manually with a follow-up text and a review link until volume justifies software. The longer-form playbook lives on the lead generation page.

9. Pick your software stack

For a California operator with employees from day one (which is most California cleaning operators, thanks to AB 5), the cleaning-business-with-employees stack is the right reference point. Two tools carry most of the load: a field-service platform like Jobber for scheduling, dispatch, quotes, and invoicing, and a payroll provider that knows how to handle California's SDI, multi-rate minimum wage, and PFL — Gusto being the common pick. The rest of the stack (books, insurance, reviews) fills in around those two.

A note on accuracy

Every fee, threshold, and rate above is current for California as of May 2026. State filing fees, the $800 minimum franchise tax, the SDI rate, the minimum wage in any given city, and AB 1978 program details all change — verify with the California Secretary of State, Franchise Tax Board, EDD, DIR, and CDTFA before relying on a specific number for a filing or a tax decision.
