Fire Benefit Charge

Fire Benefit Charge


When voters approved the creation of Renton Regional Fire Authority, they also approved the Fire Benefit Charge, a segment of the two-part funding system that fuels the organization. Unlike the Property Tax Levy, which is based solely on assessed property value, the Fire Benefit Charge is based on property factors such as building size, hazards associated with the building, and firefighting resources required. For that reason, it both stabilizes funding for critical fire and life safety services and provides owners a fairer way to distribute the cost for those services.

The Fire Benefit Charge provides a fair and balanced approach to distributing cost among taxpayers. For example, a building with a tenant storing combustible gas will pay more than a building running a small office, even if those two buildings are assessed at the same value. The building storing combustible gas has a much higher associated hazard and would require more firefighter resources in case of emergency than the office building. The fire benefit charge places more cost on the part of the building that carries more risk and resource requirements and less on the building where associated hazards are much lower, thus the required resources to protect it are lower.


Renton RFA was created out of the need for improved fire and life safety services throughout the community, particularly faster response times. Taxpayers like you enable our organization to increase staffing, upgrade equipment, expand services, and provide valuable preventive measures through public education, which improves the safety and health of the entire community. Last year, your funds helped improve life-saving response times and community services. Here’s how:

Over 5,000 Fire Inspections

Our funding mechanism has enabled our Office of the Fire Marshal to continue their exceptional work, keeping the community safe through thorough and regular commercial fire inspections. In 2020, we conducted over 5,000 fire inspections through the city of Renton.

Additional Firefighters

Despite continual retirements, a global pandemic, and significant wildfires – our funding mechanisms combined with our strategic planning has enabled us to maintain adequate staffing to continue to provide exceptional service to the Renton community and beyond.

Improved IT Infrastructure

Renton RFA has made a forward push in IT infrastructure improvements over the last few years. This investment paid off in 2020, as it became more necessary than ever to have highly functional, remote-access IT resources available to enable our team to work at full efficiency while staying safe and social distancing.

Improved Protection Class

Our improved services have also improved Renton’s Public Protection Class (PPC) rating from a 3 to a 2. We are now in the top 5% of fire and life safety agencies in the country. This PPC improvement also means potential insurance savings for Renton residents and businesses.

Pre-Incident Planning Program

We implemented the Pre-incident Planning Program to further improve the speed and efficiency of emergency response throughout the City of Renton, Fire District 25, and Fire District 40.


  • The Fire Benefit Charge applies to all buildings on the property 400 square feet in size or larger.
  • Measurements are determined based on gross square footage (measuring the outside of the building).
  • It includes each level of the building(s), basements (finished and unfinished), mezzanines, garages, and any other structure that meets the 400 square foot size.
  • Up to 60% of the Renton Regional Fire Authority budget can come from the Fire Benefit Charge.
  • The rates for the charge are set each year by the Governance Board as part of the annual budget process.
  • Every six years, voters have the opportunity to reauthorize the Fire Benefit Charge with majority voter approval.


What is the Fire Benefit Charge?

The Fire Benefit Charge is one part of the RRFA’s two-part funding system.  It is a fee that is included in your property tax which is payable to King County.  It is identified as “Fire Fee” on your property tax statement.

The fire benefit charge funding method is a voter approved, two part funding system authorized by State Law that balances general purpose taxes with a user fee charged.  Under this system, the Fire Department is funded by:

  • A property tax of up to $1.00 per $1,000 assessed values of property to support day to day operations and capital needs of the fire department; and
  • A Fire Benefit Charge of up to 60% of the operating budget, which can only be used for day to day operational expenses such as salaries, equipment, fuel and utilities.

The 1987 Washington State Legislature passed RCW 52.18, which provided that fire districts, with the approval of the voters in the district, are authorized to collect a fire benefit charge from residential and business property owners.  A similar statute was subsequently passed as part of the legislation authorizing regional fire authorities under RCW 52.26 (see specifically RCW 52.26.180 – .270).  This law allows regional fire authorities to impose fire benefit charges which shall be reasonably proportioned to the measurable benefits received by the property resulting from the services provided by a regional fire authority.  This is referred to as a “benefit charge.”

The fire benefit charge is not a per call charge and is not based on property value.  The fire benefit charge is a fee, which is based on the fire benefit of having fire protection.  The benefit charge applies to structures 400 square feet and larger and is collected by the County Treasurer’s office along with the property tax bill.

What are the factors used in determining the Fire Benefit Charge?

  • Category Factor – The category factor is based upon building use and size (residential, mobile homes, apartments, commercial).  This information is obtained from the King County Assessor database for each building subject to the benefit charge.
  • Fire Flow Factor – The relative cost of providing the required fire flow per gallon during a fire incident.
  • Effective Response Factor – The effective response force factor is relational to the size of force in firefighters and equipment required to deliver the required fire flow.
  • Hazard Factor – The hazard factor represents the degree of risk caused by the use, processing, or storage of hazard materials with a building.  The hazard factor reflects the need for larger and/or more specialized effective response forces.  Hazard factors are determined from use and risk classifications found in the National Fire Protection Association (NFPA) Standard 13 (Standards for the Installation of Sprinkler Systems), and are applicable to commercial properties only.
  • Extra Hazard Charges are as follows:
    • a.  A 15% increase for automotive fueling stations, general retail stores, eating and drinking establishments and light industrial/commercial buildings.
    • b. A 20% increase for big box retail, automotive fueling, repair, and service facilities.
    • c. A 30% increase when products or uses with high combustibility or high rates of heat release are present.
    • d.  A 40% increase when products or uses with high quantities of flammable, combustible or hazardous materials are present.
    • No surcharge will be assessed on light hazards.

What if the notification letter I received has an incorrect square footage value?

The benefit charge is calculated on the gross square footage (outside measurements) of all structures on a land parcel and includes each level of each building, and all basements, garages, lofts, mezzanines, carports, and accessory structures.  Please make sure to factor all in to your calculations.

Who establishes the Fire Benefit Charge and what does it cover?

RCW 52.26.180 provides that the Regional Fire Authority may fix and impose a fire benefit charge on personal property and improvements to real property.  The fire benefit charge does not apply to land.  The fire benefit charge would cover such property as residential buildings, commercial structures, agricultural buildings, and other structures affixed to the land.

How long is the Fire Benefit Charge good for?

Every six years, voters have the opportunity to reauthorize the benefit charge with majority voter approval.  Current authorization extends through 2022.  In addition, the state law requires annual public hearings prior to the next year’s rates being adopted.  Hearings are held prior to November 15 each year, by the Renton RFA Governance Board to establish the benefit charge.  After the benefit charge has been established, property owners subject to the charge will be notified of the amount of the charge.

The Governance Board will form a Review Board for at least a two-week period to review petitions for adjustment from property owners.  The final benefit charge will be added to the property tax bill.
