Legal, insurance, and the water rules

The entity, in the order that matters

Form an LLC before your first paid job. Filing runs $50 to $500 depending on the state, and most states sit in the lower half of that range (Wolters Kluwer). You can do it yourself through your secretary of state's website; you do not need a $500 service to type a form. The LLC's job here is specific: when a claim exceeds your insurance, the business's assets are exposed, not your house. Given that you will be spraying chlorine next to other people's property for a living, that separation is not a formality.

The sequence: register the LLC, get the EIN from the IRS site (free, ten minutes), open a business checking account with the EIN and formation papers, and put every dollar of revenue and every expense through that account from day one. Mixing accounts is the mistake that erases the liability wall you just paid to build.

Licenses are jurisdiction-dependent, full stop. Most states do not require a specialty trade license for exterior cleaning, but some require a generic contractor or home-services registration, some cities require a local business license, and a few places have pressure-washing-specific rules that did not exist five years ago. Check two sources before launching: your secretary of state's business portal and your city's business license office. One more permit that surprises people: some municipalities require a solicitation permit to go door to door, sometimes a fee and a background check. Ask the city clerk before your first door-knocking afternoon.

When you grow, revisit the structure. One Nashville operator describes switching from LLC taxation to an S-corp as the company scaled to multiple trucks, cutting his state-level tax bite on profits from 36 percent to taxing a smaller share. That is a conversation for a CPA in year two or three, when payroll and profit levels justify it. Do not let tax-structure shopping delay a June launch.

Insurance you buy before the first job

General liability is the non-negotiable policy. Pressure washing GL averages $75 to $78 a month across the major carriers, with the top of the solo market near $103 (Next, Insureon, Thimble). Standard coverage is $1 million per occurrence and $2 million aggregate, which is also the limit most commercial property managers will require before they hire you. Two extras matter as you grow: hired and non-owned auto for the truck you drive to jobs if it is insured personally, and workers' compensation the day your first helper starts, required in most states and career-ending to skip.

Insurance does something else that costs nothing: it wins jobs. "Licensed and insured" is the phrase every homeowner is scanning for, and proof-of-insurance certificates are issued free by carriers on request. Get comfortable emailing one within an hour of being asked.

Where the water goes: the rule nobody mentions

Here is the regulation that most new operators learn only from a citation. Under the Clean Water Act, discharging wash water into a municipal storm drain without permit coverage is a violation, and pressure washing runoff counts (EPA NPDES). Storm drains flow to rivers untreated. The practical industry rule that follows: nothing you wash goes into the storm sewer. Compliant operators route wash water to the sanitary sewer (a floor drain, a cleanout, or a lawn area that drains to sanitary, sometimes with local approval), let it infiltrate into landscaping, or capture and haul it (EOS Log). Enforcement lives with your city's stormwater program and varies enormously: some cities run active stings on mobile washers, most act on complaints, and a few will hand you a flyer and a recovery-system requirement on the spot.

The working habits that keep you compliant on a house wash: work in sections so rinse water carries less concentrated chemical, pre-wet and keep rinsing the landscaping between passes so dilution is high, block storm drains with a filter dam when you are doing heavy concrete work with degreaser, and collect the pooled water with a shop vacuum or pump into the sanitary system. Recovery gear is cheap relative to the fine; a drain cover, a sump pump, and a holding drum are the entry version of what commercial operators build into trailers.

Your Google Business Profile address belongs inside the service area you actually work, and it is a ranking factor for the map pack; one operator course tells the story of a business registered 30 minutes from its market that never appeared in city searches. Register where you work.

The paperwork is done. The fun part with a receipt comes later in the course.
