How to Start a Commercial Cleaning Business in California
Contract janitorial and cleaning for offices, medical, retail, and industrial buildings. Here's the California-specific path — structure, licensing for commercial cleaning work, taxes, insurance, and landing your first customers.
Licensing for commercial cleaning work in California
Rarely a specific state license, but commercial contracts almost always require a general liability policy and a janitorial (fidelity) bond, plus workers' comp once you have a crew. In California, check both your city/county and the relevant state board before you advertise.
What a commercial cleaning business needs to open
Contract janitorial and cleaning for offices, medical, retail, and industrial buildings. The setup areas that usually matter: Liability + janitorial bond, Workers' comp (crew), Per-square-foot pricing, B2B sales process, Supplies and equipment. Typical cost to get operational: $2,000–$10,000 (equipment, supplies, insurance, bonding).
Pick a structure (sole proprietor or LLC)
Most California owners start as a sole proprietor (free, no filing) or form an LLC for liability protection. The LLC filing fee is about $70, and formation typically takes about 8 business days online. Confirm the current fee on the state site before you pay.
Name a registered agent
If you form an LLC or corporation, California needs a registered agent with a physical in-state address. You can be your own agent if you're available during business hours, or hire a service for about $100–$150/year.
Get your EIN from the IRS
An Employer Identification Number is free from the IRS and takes a few minutes online. You need it to open a business bank account and to hire.
Register for California taxes
California has a state sales/use tax and has a state income tax. California's $800 minimum annual franchise tax applies to almost every LLC, even with no income.
Confirm local licenses and permits
California rarely issues a single statewide "business license" — most licensing is by city or county, plus profession-specific licenses. Check your city and your trade.
Open a business bank account and get insurance
Keep business and personal money separate from day one. General liability insurance is the baseline; some contracts also require a bond.
Put the ongoing report on your calendar
California requires a biennial report (about $20). Statement of Information; plus $800 minimum annual franchise tax to the FTB
Getting your first commercial cleaning customers in California
Direct outreach to property managers and office managers, plus referrals from complementary vendors (HVAC, landscapers). Property managers and facility managers control multiple buildings — land one and you can grow the account. Contracts are typically month-to-month with 30-day terms.
