Illustration for California Pressure Washing

Two governments are involved. The Contractors State License Board (CSLB) licenses anyone who builds or alters a structure when the job needs a permit, uses any additional workers or totals $1,000 or more in labor and materials; Assembly Bill 2622 raised that line from $500 on January 1, 2025. Cities run their own business licenses: the City of Orange, for one, requires a current license from all commercial, industrial and residential businesses operating or based in the city.

Which case is yours

If… Then Because
The job is under $1,000, needs no permit and you work alone The minor work exemption can cover it The state board’s exemption covers labor and materials under $1,000 combined, with no permit and no employees.
You bring even one helper Get licensed or keep the job solo The board says hiring one or more workers means a license is required even if the project is less than $1,000.
An HOA or commercial job comes to $1,000 or more Don’t split it into smaller invoices The board says a larger project may not be split to fit the exemption; a first unlicensed-contracting offense carries up to a $500 fine plus a potential $200 to $15,000 administrative fine.
Your scope includes prep before paint or sealer Ask the board in writing about the D-38 class D-38 covers using abrasive materials or water to clean or prepare surfaces for a protective, decorative or functional treatment.
You decide to get the D-38 Budget at least $650 in board fees plus a bond The board lists a $450 application and a $200 initial license fee for a sole owner, a $25,000 bond and four years of experience.
The job is in a city you’re not based in Apply for that city’s business license The City of Orange says any business coming into the city to work must apply; its application fee is $79 plus a $4 state-mandated fee.

What the paperwork costs against one house wash

A typical house wash is $325 in our price index, with the middle half of companies at $224 to $350, so a solo residential job sits well under the $1,000 line. The fees, worked through:

Path Arithmetic Fees
One city license application at Orange’s rate $79 + $4 $83, about a quarter of one house wash
Five cities at that rate 5 × $83 $415, if each charged what Orange does
State license, sole owner $450 + $200 $650, two house washes, before the bond and any other board charges

Orange says its license covers only the City of Orange, not the county or other Orange County cities, and contractors give the job location and value on the application. The D-38 sits under the board’s C-61 Limited Specialty class, and the four years of experience must fall within the past ten, at journey level or as a foreman, supervisor or contractor. Whatever you ask the board, describe your exact scope and keep the written reply.

A first helper changes more than the license: see employee or 1099 for your first helper.
