Redmond, WA Development Impact Fees (2026)

All figures are from the City of Redmond's current official "Impact Fees Schedule – Effective January 1, 2026" (adopted per Ordinance 3240, established/revised per RMC 3.10) and the City's official Water/Sewer System Connection Fee schedules (both stamped EFFECTIVE DATE: January 1, 2026). As of the verification date (2026-06-17) these are the current adopted schedules. WHAT EXISTS HERE (residential): (1) SCHOOL impact fee — Washington allows school impact fees and Redmond collects them on behalf of Lake Washington School District (LWSD), per its 2025-30 Six-Year Capital Facilities Plan. 2026 SFD = $7,277.00, multifamily = $170.00. A $65.00 school admin fee is added to the school impact fee (included as a separate row). (2) FIRE impact fee. (3) PARKS impact fee. (4) TRANSPORTATION impact fee — Redmond charges TWO rate columns: a base "per Development Unit" rate and a lower "per Development Unit in Centers" rate (Overlake Metro Center, Downtown Redmond Urban Center, Marymoor Village Center). The base (non-Centers) rate is used as primary; the Centers rate is included as excludeFromTotal=true. (5) WATER connection charge (City of Redmond Redmond Service Area). (6) SEWER connection charge (City of Redmond Redmond Service Area).

Water fee structure caveat

Redmond's residential water connection is tiered by HOME SIZE (Small <1,500 SF = $4,230; Medium 1,500-2,999 SF = $5,380; Large 3,300+ SF = $7,130) and assumes a 1" meter for domestic use. ADDITIONALLY and additively, a Regional Water Connection Charge (CWA, includes 3% admin fee) of $9,118 is imposed on every property connecting to the City water system — this is NOT a mutually-exclusive variant, it is an additive charge. A "Water System Distribution Credit" (e.g., -$1,590 for a medium home) is a MAXIMUM credit only granted if the developer builds qualifying hydrants/mains/pumps that become City-owned; a typical infill builder who builds no such mains gets no credit, so it is NOT netted into the primary total (shown as an informational excluded row). Primary water row = Medium Home (representative ~2,000-2,500 SF) $5,380 + CWA $9,118.

Sewer fee structure

Redmond residential sewer connection is also tiered by home size (Small <1,500 SF $2,470; Medium 1,500-2,999 SF $3,050; Large 3,000+ $3,540). Multifamily ">Larger than 4 Units" = $1,920/unit. A side-sewer inspection/new-connection fee ($1,722.55, +4% tech surcharge) also applies but is a permit/inspection fee rather than a capacity charge (included with excludeFromTotal note for completeness).

Separate-district fee

King County (not the City) levies the regional wastewater CAPACITY CHARGE on every newly-connecting parcel: $77.99 per residential customer equivalent (RCE) per MONTH for 2026, billed for 15 years (payable as a lump sum at a discount). Because this is a recurring monthly charge over 15 years rather than a one-time fee at building permit, it is included as an informational row (excludeFromTotal=true) and should not be summed with the one-time fees. A builder/buyer in Redmond DOES pay this.

What does not exist here

No standalone POLICE impact fee, no DRAINAGE/stormwater impact fee, no LIBRARY impact fee, no OPEN SPACE impact fee, no general/capital impact fee, and no separate AFFORDABLE HOUSING impact fee in the impact fee schedule. Washington's RCW 82.02 impact-fee categories are limited to transportation, parks, fire (public facilities), and schools — Redmond levies all four. No water/sewer "GFC" terminology is used; Redmond calls them "connection charges." Highway-district fees: none. NOTE ON 2025 vs 2026: School and Transportation fees rose in 2026; Fire fees are unchanged ("same as 2025 rates"); Parks rose slightly. Multifamily school fee changed from $0.00 (2025) to $170.00 (2026).

Independently re-fetched the 2026 Impact Fees Schedule PDF (DocumentCenter/View/40265), the Water System Connection Fees PDF (View/4128), and the Sewer System Connection Charges PDF (View/4127) via curl + pdftotext, and the King County capacity charge page via WebFetch. Every amount and sourceQuote matched the source text verbatim (incl. the source's own typo "EFFECIVE 1/1/2009" in the CWA note, and the side-sewer "New connection within property $1,722.55*"). King County 2026 capacity charge confirmed at $77.99 per RCE per month, billed for 15 years. excludeFromTotal corrections: none — all flags were already correct. Primary one-time SFD total of the non-excluded rows = $7,277 + $65 + $148.78 + $6,914.63 + $10,107.51 + $5,380 (water size tier) + $9,118 (additive CWA) + $3,050 (sewer) = $42,060.92, with no double-counting (multifamily/Centers/other-size-tier/inspection/county rows correctly excluded). Confidence levels unchanged and appropriate (side-sewer inspection fee left at medium as a permit fee; all others high).
