Coverage & caveats
WHAT EXISTS in Renton (RMC 4-1-190, authorized under RCW 82.02): transportation impact fees, park impact fees, fire impact fees (Renton Regional Fire Authority — a separate district; the city collects on its behalf), and school impact fees.
School impact fees
three school districts serve Renton's city limits — Renton SD No. 403 ($1,003 SFR / $3,268 MF & ADU per dwelling), Issaquah SD ($4,728 SFR / $0 MF), and Kent SD ($0 / $0). These are MUTUALLY EXCLUSIVE by parcel location; the Renton School District SFR figure is the primary representative row and the other districts are included as excludeFromTotal variants. School districts set the fee via their Capital Facilities Plan; the city adopts/collects it. UTILITY SDCs: water ($5,025), wastewater/sewer ($4,025), and storm/surface water ($2,350 per new SFR/ADU) System Development Charges, priced by meter size for water/sewer (base 5/8x3/4" & 1" meter is primary). A separate Fire Sprinkler Service SDC ($671 at base meter) applies only if a separate fire sprinkler service is installed — included as an excludeFromTotal optional row.
Separate regional district
Renton sewage flows to King County's regional wastewater treatment system, so new sewer connections also owe the KING COUNTY WASTEWATER CAPACITY CHARGE ($77.99 per residential customer equivalent per MONTH for 2026, billed quarterly for 15 years, with a discounted lump-sum prepayment option) — this is a recurring monthly charge, not a simple one-time tap fee, so it is recorded as an excludeFromTotal informational row and NOT folded into the connection-fee total. WHAT DOES NOT EXIST in Renton: no POLICE impact fee, no LIBRARY impact fee, no standalone OPEN SPACE impact fee (open space need is funded via the park impact fee — RMC 4-1-190 defines "Parks" to include open space and recreation facilities), no GENERAL/capital-facilities impact fee beyond the categories above, and no DRAINAGE impact fee separate from the storm water SDC.
Affordable housing
Renton has no mandatory affordable-housing impact fee; there is a voluntary 'Affordable Housing Cash Payment in Lieu' option tied to an inclusionary/incentive program and a Multifamily Tax Exemption application fee ($1,000) — these are program-specific/optional and excluded from the residential builder total. A $225/diameter-inch tree fee-in-lieu also exists (excluded).
Caveat
the King County capacity charge 2025 monthly figure was not separately published on the official page (only the 2026 rate of $77.99/RCE/mo was stated); confidence on that single row is medium.
Verify
confirmed 22 of 22 rows; dropped 0. All amounts and source quotes were verified verbatim against the official City of Renton Fee Schedule 2025-2026 PDF (MRSC-hosted, sourceIndex 0) and the King County Wastewater Capacity Charge page (sourceIndex 2, $77.99/RCE/mo 2026 confirmed). RMC 4-1-190 (sourceIndex 1) confirmed via curl: transportation/park/fire/school impact fees under RCW 82.02, Renton Regional Fire Authority referenced, no police/library impact fee, open space subsumed in parks. excludeFromTotal corrections: none — all flags already correct (transportation townhouse & ADU; Issaquah & Kent SD service-area variants; 1.5"/2" meter-size variants; fire sprinkler optional SDC; King County recurring capacity charge all properly excluded; representative SFR rows for transportation/parks/fire/school-Renton/water/sewer/storm correctly included, one per category, no double-counting; representative SFR connection+impact total ≈ $27,587). Confidence on the King County capacity-charge row left at medium per the published-data caveat.
All impact fees and utility SDCs are from the adopted City of Renton Fee Schedule 2025-2026 (SECTION XII. Development Fees), the city's official master fee document. Fees are unchanged between 2025 and 2026 columns. Transportation impact fees use ITE Land Use Codes; single family house (ITE LUC 210) = $11,485.67/unit is the primary SFR figure. Note two transportation caveats from the schedule: (1) commercial/retail/industrial uses are reduced to 88.97% of calculated (except uses with PCE factors which remain at 100%), and (2) all uses within the Center Downtown (CD) Zone are reduced to 20% of the assessed transportation impact fee — these do not change the standard residential figures. Water/sewer SDCs are priced by meter size; base residential 5/8x3/4" and 1" meter is the primary; larger meter sizes (1.5", 2", 3", 4", 6", 8") are included as excludeFromTotal variants. A 5% school impact fee administration charge applies on top of the school impact fee. A $100 per-unit impact fee deferral administration fee and a $560 independent fee calculation review fee also exist (excluded from primary totals as optional/administrative).
