Insurance for Charity and PTA Car Wash Events: What a Host Wash and a Fundraising Group Should Sort Out First

A charity or PTA car wash at your location raises questions that a normal wash day does not. Who is covered when volunteers vacuum and dry? What happens if a volunteer scratches a customer’s car? What does the group’s own insurance do? The honest answer is that published sources leave most of this to the policy and to state law, so this post sets out what agencies say and what to ask.

It is written for car wash owners who host or sponsor events, and for the groups that approach them. It is not a statement of coverage for any policy.

Why Fundraisers Point to Commercial Washes

The environmental case is simple. An EPA stormwater fact sheet says most stormwater impacts from car washing come from residents, fleet activities and charity car wash fundraisers that discharge polluted wash water into the storm drain system. It adds that commercial car washes minimize those impacts because they often recycle water or must treat it before release to the sanitary sewer.

Local agencies say the same thing in practical terms. The Maryland Department of the Environment’s fact sheet advises groups to consider holding a fundraiser at a commercial car wash because the water goes to sewage treatment rather than down a storm drain, and to call a local wash to ask whether it offers fundraising options. Honolulu’s storm water program lists commercial wash coupons as an alternative to on-site washing.

None of this is a request to open your wash to every group. It explains why groups will ask, and why a thoughtful answer helps your community.

Charity Washes Are Not Banned, but the Water Is the Issue

Owners sometimes hear that fundraiser washes are illegal. The agency documents say something narrower. A Town of Truckee flyer states that fundraiser car wash activities are not prohibited while discharges of wash water to the storm drain are prohibited by state and local rules. The flyer is dated 2009, so confirm current local rules. Honolulu’s flyer says fundraisers are still allowed, but wash water from them may not enter city storm drains, and the host site and organizers are responsible for disposing of it appropriately.

The International Carwash Association’s 2002 report also records that in some communities charity car washes have been discouraged or banned anywhere other than at a professional wash. It is dated, so treat it as background, not current law. When a group wants to wash in a parking lot, the safe course is to point them to your local stormwater program.

Two Ways a Wash Can Host

Most arrangements fall into two shapes. In the first, the group sells tickets or vouchers that customers redeem at your wash, and you wash the cars as normal. Truckee notes that some commercial washes have vouchers or tickets groups can sell, and EPA describes a Seattle program in which groups buy tickets at a discount from a partner wash and sell them at a profit.

In the second, you host a wash day. An ICA news item describes one operator who runs the wash, gives a share of wash sales on event days to the participating organization, and has charity volunteers vacuum and dry vehicles and accept donations. That describes one operator, not a standard practice.

The insurance picture differs between the two. A ticket arrangement keeps your people on the equipment. A host day puts volunteers at your wash and sometimes near customer vehicles.

Volunteers and Workers Compensation

This is the part owners most often get wrong. State agencies treat volunteer status as a question of facts, and the pages differ. Washington’s Department of Labor & Industries says that if a volunteer receives something of monetary value for work, they are probably a covered worker, while reimbursement of actual expenses does not by itself make someone one. Wisconsin’s Department of Workforce Development states that volunteers are not covered by its act, though a non-profit may cover them under its own policy. Alaska’s Department of Labor says volunteers are not covered in most circumstances but may be employees depending on an investigation, to be decided case by case.

The safe reading is that it varies by state, and that receiving something of value, such as a discount, a share of sales or a voucher, is the kind of fact the Washington and Alaska pages treat as relevant. Do not assume that a wash-day arrangement does or does not make a volunteer an employee. Ask your state agency and your underwriter, using the specific arrangement.

General Liability, Event Liability and Additional Insureds

The Insurance Information Institute describes general liability as covering bodily injury and property damage to others, with medical payments for non-employees paid on a no-fault basis, and says workers compensation is excluded and pollution is generally excluded. That is the standard structure, not a promise that any particular policy covers an event.

The NAIC’s consumer article explains that event liability insurance covers injury or property damage to others as a result of an event, that some venues require clients to carry it and to add the venue as an additional insured, and that you should check with your agent about whether a policy extends to a scheduled event. Those points are general, but they suggest a reasonable ask: that the group carry its own event liability and name your wash as an additional insured.

Real-World Scenario: A school group approached a wash owner about a Saturday fundraiser where students would vacuum and dry vehicles. The owner asked the agent three questions before agreeing: how the policy treated injuries to volunteers, whether the group should name the wash as an additional insured, and whether a one-day event needed to be reported. The agent could answer two from the policy, and the third required a call to the underwriter. The owner agreed to the date only after the answers came back in writing.

Customer Vehicles and Non-Employees

The hardest question is whether your coverage responds when someone who is not on your payroll damages a customer’s car. General liability excludes property in your care, custody or control, a concept the IRMI reference defines as an exclusion that is addressed by more specific policies such as garagekeepers. Our explainers on what garagekeepers coverage is and how a claim actually pays cover that structure.

We found no source stating how garagekeepers treats damage by volunteers. The safest approach is to keep volunteers away from customer vehicles, or to ask your underwriter in writing whether your garagekeepers form responds to damage by someone who is not an employee, and whether the policy requires supervision or training.

If You Host on Your Own Lot

A host day can tempt you to let a group wash in your vacuum area or lot. That creates the exact storm drain problem agencies warn about, now at your own wash, and Honolulu’s flyer says the host site shares responsibility for disposing of wash water. Keep any hand-washing inside the wash bays and discharge to your own sewer connection, where your site’s separator and permit apply. Our guide to water reclamation and discharge rules by region explains who controls discharge in several markets.

Keep the event on the equipment you already insure and monitor. Self-serve bays used by a group still carry the exposure of wet surfaces and high-pressure equipment, which is a general liability concern, and a tunnel is not a place for untrained volunteers at all.

A Simple Host Checklist

Write the arrangement down, even for a one-day event. Name the date and hours, who supervises, which tasks volunteers may do and which they may not, where vehicles queue, and where wash water goes. State whether the group or you supplies insurance and whether the other party is named as an additional insured. Decide how customer-vehicle damage is reported and who handles it. Keep a record of what you told your agent and what the agent said, because a policy question settled by phone is hard to prove later.

Sponsoring through tickets avoids most of this. If your goal is to help a group without taking on event risk, a voucher program keeps volunteers off your equipment and your customers’ vehicles, while still sending the group money and your wash new customers. The workers compensation page explains why volunteers near equipment deserve care.

Questions to Put to Your Underwriter Before the Day

• If volunteers vacuum, dry or hand-wash vehicles, how does the policy treat their injuries, and does our state treat them as employees if they receive donations, a share of sales or tickets?
• Does general liability respond to a customer or volunteer injured at an event hosted with an outside group, and does it matter whether the group is named?
• Should the group carry its own event liability and name us as an additional insured, and what limits do you want?
• If a volunteer damages a customer’s vehicle, which coverage responds?
• Do policy terms restrict third-party operations on the premises, and must a one-day event be reported?
• If wash water reaches a storm drain and a regulator issues a penalty, does any coverage apply?

Frequently asked questions

Is a charity car wash legal?

Generally yes, but the water is the issue. A Town of Truckee flyer says fundraiser car wash activities are not prohibited while discharges of wash water to the storm drain system are, and Honolulu says fundraisers are still allowed but the wash water may not enter storm drains. Rules vary by place, so check with your local stormwater program.

Why do agencies suggest holding a fundraiser at a commercial car wash?

Because wash water from commercial washes goes to the sewer for treatment rather than down a storm drain. The Maryland Department of the Environment suggests calling a local car wash to ask about fundraising options, and EPA describes ticket programs with commercial washes as an alternative. It is a stormwater point, not an insurance one.

Do volunteers count as employees for workers compensation?

It varies by state and by the facts. Washington’s Department of Labor & Industries says receiving something of value beyond expenses may make a volunteer a covered worker, Wisconsin says volunteers are not covered by its act, and Alaska decides case by case. Ask your underwriter and your state agency how your arrangement is treated.

Does my general liability policy cover a fundraiser at my wash?

We cannot say, and no source we found answers it for car washes. General liability generally covers bodily injury and property damage to others, but it has exclusions, and policies differ on events. Ask your agent whether the policy responds to a scheduled event, whether the group should name you as an additional insured, and whether one-day events need to be reported.

What if a volunteer damages a customer’s car?

We found no source that addresses this directly. Customer-vehicle damage is normally a garagekeepers question, and general liability excludes property in your care, custody or control. Whether a non-employee’s work is covered depends on the policy wording, so ask your underwriter how your garagekeepers coverage treats vehicles handled by people who are not on your payroll.

Should the group carry its own insurance?

Often it is worth asking. The NAIC notes that event liability exists as a coverage, that venues sometimes require clients to carry it, and that you can ask to be added as an additional insured. Whether it is right for your event is a question for your agent and the group’s own insurer.
