Car wash insurance, format by format
A car wash's coverage follows its format. Tunnel and automatic washes are machinery businesses whose product touches customer cars all day, self-service bays are premises and equipment risk, and mobile washing and detailing carry the whole operation to the customer's driveway. The common thread is the custody question: what happens when a customer says your wash damaged their car.
Garage liability vs garage keepers
Tunnel and automatic: machinery with customers inside it
The premises core reads as it does for any customer-facing business: general liability for the NAIC's categories, bodily injury and damage to others' property in front (NAIC, Insure U: Small Business Insurance), with wet pavement doing here what it does at every business built on water. Property coverage carries the building and the machinery, and a tunnel is expensive machinery; equipment breakdown, the coverage for machinery failing from within rather than burning or flooding, deserves its own question, because a wash earns only while the line moves.
The claim pattern that defines the trade is the customer's car in the tunnel. A vehicle moving through your equipment is in your operation's control, and damage claims from those minutes are this business's version of the custody exposure that garagekeepers coverage exists for in the garage trade (IRMI). Which variant answers, and whether it responds only when you are liable or regardless, is the decision walked through on our garage liability vs garage keepers page. Have it settled before the first damage claim, not during.
Self-service, mobile, and detailing
Self-service bays trade the custody exposure for a premises-and- equipment one: customers wash their own cars, and the risks are wet pavement, vandalized changers and vacuums, and machinery uptime. The insurance conversation is simpler, and honest about being so.
Mobile washing and detailing are the same business with the premises removed, which makes them cousins of the premises-less trades covered on our mobile mechanic insurance page: liability at the customer's location, a van and tank under commercial auto coverage, since personal policies may exclude business use, and equipment as property in motion. Water supply and runoff handling vary by locality and belong in the operational conversation with your jurisdiction as well as your agent.
Every format adds workers compensation once there are employees, required in nearly all states, and every format obeys the standing rule: the policy covers the operation it was told about, so name the formats you actually run, detailing add-ons included. Or start at the overview.
