Washington Tow and Storage Fee Dispute: Walking the 135-Percent Caps Under RCW 46.55.118
Most Washington towing disputes end up as fee disputes once the procedural questions clear. The tow happened, the signage was there, the authorization was signed, the notice arrived. The only question left is whether the operator overcharged you. RCW 46.55.118 answers that question by reference to the operator's filed rate sheet on file with the Washington State Patrol: towing at 135 percent of the maximum hourly Class A rate, storage at 135 percent of the maximum daily storage rate, after-hours release at 100 percent of the maximum after-hours release rate. The math is straightforward once you have the filed rate. The work of a fee-dispute demand letter is usually about getting the filed rate sheet in writing and walking it line-by-line against the itemized invoice the operator is required to produce under RCW 46.55.063.
What the statute caps and what it does not
RCW 46.55.118 sets three caps for private impounds by registered tow truck operators using Class A, E, or D tow trucks.
- Towing rate. The hourly towing rate may not exceed 135 percent of the maximum hourly rate negotiated by the Washington State Patrol with the operator class.
- Daily storage rate. The daily storage rate may not exceed 135 percent of the maximum daily storage rate.
- After-hours release fee. The after-hours release fee may not exceed 100 percent of the maximum after-hours release fee. The lower cap (100 percent rather than 135 percent) reflects a legislative choice that the after-hours fee should not exceed the underlying rate.
The statute does not categorically cap gate fees, administrative fees, notification fees, or other ancillary line items. The statute does not specify a single statewide dollar number; the cap is calculated against the operator's filed rate. That makes the filed rate sheet the controlling document in any fee dispute.

The itemization rule: RCW 46.55.063
The other half of the fee analysis is the recordkeeping and itemization rule. RCW 46.55.063 requires the operator to file a fee schedule with the department and to issue billing invoices that are itemized so each individual fee is clearly discernible to the redeemer. The statute also requires that towing contracts with private property owners be in writing, that records be retained for three years, that tow truck fees be calculated hourly, and that storage fees be calculated on a twenty-four-hour basis charged to the nearest half-day. An operator that issues a one-line invoice with "tow and storage $XYZ" is not complying with the itemization requirement, and the demand letter should request a compliant itemized invoice in writing.

How to walk the math
The arithmetic for a fee dispute looks like this. Start with the operator's itemized invoice under RCW 46.55.063. For each line, identify which RCW 46.55.118 cap applies (if any), look up the filed-rate number for that line, compute 135 percent (or 100 percent for after-hours release), and compare. Storage is the most common overcharge because operators charge by partial days, hold the vehicle longer than necessary, or apply a higher daily rate than what was filed.
- Towing line. Identify the Class A hourly rate filed by the operator on the date of the tow. Multiply by 1.35. Compare against the towing line on the invoice. If the operator charged for a one-hour minimum on a fifteen-minute hook-and-go, the half-hour increments in the filed rate matter.
- Storage line. Identify the maximum daily storage rate the operator filed. Multiply by 1.35. Multiply that by the number of days storage actually accrued, rounded to the nearest half-day per RCW 46.55.063. Compare against the storage line on the invoice. Operators sometimes charge a "first-day" rate plus subsequent daily rates that, in combination, exceed the statutory cap.
- After-hours release. Identify the after-hours release rate the operator filed. Multiply by 1.00. Compare against the after-hours line on the invoice. A 135-percent calculation on this line is itself an overcharge.
- Gate fee, admin fee, notification fee. The statute does not categorically cap these, but it does require the operator to file the fee schedule and to itemize. A line item that is not on the filed fee schedule is a candidate for refund as an unauthorized charge regardless of the percentage analysis. The notification or "DOL search" fee is sometimes charged in a way that duplicates what the chapter already requires the operator to do.
- Storage clock disputes. Storage runs from impoundment until redemption, but the operator's obligation to give notice under RCW 46.55.110 means a delay caused by the operator (late or wrong-address notice) is a candidate for fee credit. The hearing officer often credits storage during the period when notice was delayed because the customer could not have redeemed without knowing the vehicle was impounded.
The filed rate sheet is the case
The operator's filed rate sheet on file with the Washington State Patrol is the single most useful document in a fee dispute. The operator already has to produce it for any hearing under RCW 46.55.120; the State Patrol has it on file; the operator's own front-desk staff is supposed to be able to refer to it on request. A demand letter that asks for the filed rate effective on the date of the tow, in writing and within a specific window, often produces the rate sheet (which makes the math easy) or a refusal (which is itself evidence and supports a separate complaint to the State Patrol and a stronger argument at the hearing). The leverage is asymmetric: producing the rate sheet costs the operator almost nothing if the charges actually comply, and refusing to produce it almost always signals that the charges do not.
What a tow and storage fee dispute demand letter should do
- Identify the impound with date, time, location, vehicle, operator name, and registered-tow-operator number.
- Quote the invoice line by line and demand a compliant itemized invoice under RCW 46.55.063 if the invoice does not break out each fee.
- Demand the filed rate sheet effective on the date of the tow, in writing.
- Walk the 135-percent and 100-percent caps under RCW 46.55.118 against the filed rate for each line where the cap applies.
- Identify each line that is not on the filed fee schedule as an unauthorized charge.
- Account for any storage credit due to a delayed or non-compliant notice under RCW 46.55.110.
- Demand a refund of the computed overage, with a written confirmation that the operator will use the filed rate going forward.
- Reference the hearing right under RCW 46.55.120 as a parallel track. The fee math is also the case at the hearing.
- Use the CPA frame under Chapter 19.86 RCW only when the facts show a pattern across multiple customers, not for a single math error.
- Document transmission: certified mail with return receipt, plus email.
Documents to upload before the letter goes out
- The itemized invoice and the redemption receipt.
- The impound notice and the envelope showing postmark date.
- Photographs of the vehicle at redemption.
- The filed rate sheet for the operator effective on the date of the tow, if you can obtain it.
- Any prior written correspondence with the operator about the charges.
- Bank, credit card, or payment-app statements showing the redemption payment.
- A short dated timeline: when the tow happened, when notice arrived, when you redeemed, when storage accrued each day.
Sergei's practical note
Most Washington fee-cap matters are won on the filed rate sheet and the storage math. The first thing I do when a fee dispute comes in is request the filed rate from the operator in writing. If the operator produces it, the case usually collapses into clean arithmetic that the operator settles to avoid the hearing. If the operator refuses to produce it, the refusal itself is evidence and the State Patrol complaint becomes part of the strategy. Either way, the fee analysis is not actually hard; it is just tedious. A $200 storage overcharge on a five-day impound is a real refund, and an operator who refunds quickly avoids both the hearing and the cumulative pattern-and-practice exposure if other customers are being charged the same way.
When this becomes worth hiring an attorney
- The operator has refused to produce the filed rate sheet or has produced an obviously wrong version (different effective date, different operator name).
- The overcharge across tow, storage, and after-hours release exceeds roughly $300 to $500.
- You have evidence the same operator is overcharging multiple customers (online reviews quoting the same pattern, multiple State Patrol complaints, signs of a pattern in the operator's filed-rate history). At that point the matter becomes a candidate for the CPA frame under Chapter 19.86 RCW.
- The fee dispute is bound up with a wrongful impound argument or a procedural defect, in which case the fee math becomes a backup argument to the broader fee-shift under RCW 46.55.120.
