Do I need a license to start a pressure washing business?

No state requires a specific 'pressure washing license', but almost all cities and counties require a general business license or tax registration. Some states treat exterior cleaning as contractor work that needs registration. Check your city clerk and state licensing board.

What permits do I need for pressure washing?

Most residential jobs need no permits. Commercial sites, HOAs and municipalities with water-use restrictions may require a business permit or proof of insurance. Some cities restrict wastewater runoff - check local stormwater rules.

What do clients require from a pressure washing company?

Proof of general liability insurance ($1M+), a business license, and often an additional-insured certificate. HOAs and property managers usually require all three before booking.

Pressure Washing License and Permits by State

The short answer: no state licenses "pressure washing" specifically - but every city has a business license, and clients will ask for insurance certificates. Here is the checklist that keeps you legal and bookable.

The three-layer checklist

Layer	What you need	Typical cost
Federal / state	EIN (free, IRS) - required to open a business bank account and hire later	$0
State / local	Business license or tax registration (city/county clerk)	$50 - $300/yr
Trade	Some states classify exterior cleaning under contractor licensing (e.g., California CSLB requires a license for jobs over $500; Florida requires a local business tax receipt)	$150 - $500

States where contractors need extra care

California - any job over $500 requires a CSLB contractor license (class C61 is the common path for cleaning/washing).
Florida - local business tax receipts vary by county; some require contractor registration.
Texas - no state pressure washing license; county business registration + sales tax permit (washing is generally taxable service).
Georgia / North Carolina - general contractor registration may apply for large commercial jobs.

Always confirm with your city clerk and state licensing board - rules change, and "I did not know" is not a defense.

What clients will ask for

Certificate of general liability insurance (with them named as additional insured).
Business license copy.
Written quote with square footage and line items.
Wastewater handling statement where runoff rules apply (keep wash water out of storm drains).

Common mistakes

Working a year before registering - a customer complaint then becomes a compliance problem.
Skipping insurance to "save $50/month" - one water-damage claim costs more than ten years of premiums.
No written quotes - verbal pricing is how disputes start. Send a branded quote for every job.
