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

In most U.S. states, no specific trade license for pressure or soft washing — it's not classified as a regulated contractor trade the way electrical, plumbing, or roofing are. What you do need almost everywhere: a registered business entity (LLC most common), a state sales tax permit if your state taxes services, $1M general liability insurance, and workers comp if you have employees. A handful of states (FL, CA, OR, NV) require occupational or contractor's licenses above a revenue threshold. Not legal advice — check your state.

What insurance does a cleaning company need?

$1M general liability is the universal floor — costs $40-$80/month for a single-truck operation. Add workers comp if you have W-2 employees (state-mandated). Add commercial auto for any truck used for jobs. Add a $1M umbrella once revenue crosses $250K. Some homeowners' associations and commercial accounts will require $2M liability — keep the higher policy on file and pull it up on a phone when asked. Don't go bare on insurance to save $60/month; one ladder fall from a second story will end the business.

Is sodium hypochlorite a regulated chemical?

At residential cleaning concentrations (12.5% pool-grade or lower), SH is sold over-the-counter and doesn't require a special federal license to use or store. The thresholds that trigger regulation: transporting over 1,000 lb requires DOT hazmat compliance; storing over 500 gallons triggers SARA Title III community reporting in most states; municipal wastewater rules can apply if rinse runoff hits a storm drain. For typical single-truck residential cleaning operations, none of these apply — but check local stormwater rules before pumping rinse into a public drain. Not legal advice.

Do I Need a License for Pressure Washing? (State Reqs)

Q: Do I need a roofing license for roof soft washing?

In most states, no — soft washing a roof at low pressure is not classified as roofing work because nothing structural is being modified. A handful of states (Florida is the clearest example) interpret 'work performed on a roof' broadly enough that a roofing contractor sub-license may be required, especially over a revenue or scope threshold. If your service area includes Florida, North Carolina, or Texas, check the state roofing board specifically before booking roof jobs. Not legal advice.

Not legal advice

This page is informational. Licensing rules vary significantly by state, county, and city, and they change. Consult a licensed attorney or your state contractor licensing board before operating an exterior cleaning business. Insurance + bonding requirements vary by client type (residential, HOA, commercial).

The short answer: most states do not require a trade license to pressure wash or soft wash. What essentially every state does require: a registered business entity, a sales tax permit (if the state taxes services), and $1M general liability insurance. A few states layer on contractor or occupational licenses. Roof washing has the most variation.

What you almost certainly need everywhere

Registered business entity. LLC is the standard for single-owner operations. Sole proprietorship works but offers no liability shield.
EIN. Free from the IRS, takes 10 minutes.
State sales tax permit. Required if your state taxes services (varies wildly — most states tax some services).
$1M general liability insurance. The universal floor for residential. $40-$80/month for a single-truck operation.
Workers comp. If you have W-2 employees. State-mandated almost everywhere.
Commercial auto. If you use a truck for jobs.

What varies by state

Florida: No statewide pressure washing license, but local jurisdictions (Miami-Dade, Broward) require occupational licenses. Soft washing roofs may trigger roofing license requirements above scope thresholds.
California: CSLB requires a contractor's license for any single job above $500. This catches almost every cleaning job. The C-61/D-38 "Sand and Water Blasting" sub-classification covers pressure washing.
Oregon and Nevada: Require general contractor or occupational licenses above revenue thresholds.
Most other states: No specific trade license required for residential exterior cleaning. Business registration + insurance only.

Roof washing exceptions

Roof soft washing is the gray area. In most states it's treated as cleaning, not roofing, because no structural modification happens. A handful of states interpret "work performed on a roof" broadly enough that a roofing contractor sub-license may be required:

Florida: CILB has gone back and forth on whether soft washing requires a roofing license. Currently most operators run under the cleaning interpretation — but if you're scaling in FL, get an attorney opinion.
North Carolina: Limited license rules can trigger above $30K project scope.
Texas: No state roofing license at all, so soft washing is unambiguously cleaning.

Chemical handling

Sodium hypochlorite (SH, pool-grade bleach) is the standard soft-wash chemistry. At residential concentrations and typical single-truck volumes, no federal license is required to use or store it. The thresholds:

DOT hazmat: Transporting more than 1,000 lb of SH triggers DOT placarding and hazmat endorsement on the CDL. Single-truck residential ops don't hit this.
SARA Title III: Storing more than 500 gallons triggers community right-to-know reporting in most states. Again, single-truck ops don't hit this.
Stormwater: Municipal rules may prohibit pumping rinse into storm drains. Reclaim or divert to landscaped soak areas where required.

Insurance baseline

$1M general liability: The floor. Don't go below.
$2M general liability: Required by most HOAs and commercial accounts.
$1M umbrella: Add once revenue crosses $250K. Cheap insurance against ladder accidents and chemical drift damage.
Equipment / inland marine: Covers stolen or damaged pressure washers and soft-wash pumps. $20-$40/month for $20K of equipment.

Bonding

Most states don't require a bond for residential cleaning operators. Commercial accounts and HOAs sometimes do — typically a $10K-$25K performance bond. Add only when a specific account requires it; don't carry a bond preemptively.
