Coverage & caveats
RESIDENTIAL DEVELOPMENT IMPACT FEES (City of Post Falls, per housing unit, effective FY2026 / 10-1-2025), confirmed VERBATIM in the official Fee Schedule PDF (Revised 10-1-2025) IMPACT FEES table: Single-Family total = $14,221 (Parks $6,721 + Public Safety/Police $1,302 + Streets $3,311 + Multimodal $1,447 + Fire $1,298 + EMS $142). Multi-Family total = $10,370 (Parks $5,004 + Public Safety $978 + Streets $1,871 + Multimodal $1,077 + Fire $1,298 + EMS $142). The schedule also lists non-residential impact fees per square foot of floor area (Commercial/Shopping Center $10.10/sf, Office $4.42/sf, Light Industrial $2.64/sf, etc.) which were not requested as individual rows here. ATTRIBUTION OF SEPARATE-DISTRICT FEES: Fire ($1,298) and EMS ($142) are line items in the City's adopted Fee Schedule IMPACT FEES table and reflect Kootenai County Fire & Rescue / Kootenai County EMS components collected by the City at building-permit issuance. The 2021 City TischlerBise study covered only parks/public safety/streets/multimodal (NOT fire/EMS). No separate per-unit Post Falls Highway District road impact fee was found published; City road impacts are captured by Streets + Multimodal. WATER & SEWER CONNECTION/CAPACITY FEES (official Fee Schedule PDF, Revised 10-1-2025, all confirmed verbatim): Water Capitalization $3,278 for the standard 3/4\"-1\" residential meter (primary; larger meter sizes are mutually-exclusive excluded variants); Sewer Capitalization $7,621 per 1 Service Unit (single-family); plus a flat $5.00 Sewer Connection/Hookup. 'Water Meter = Cost of Meter' and the 'Typical Dig In' service-installation charges ($2,351.25 for 1\") are physical-install costs, not capacity fees (1\" dig-in included as excluded variant). Utility Deposit $60 (refundable, not an impact fee — omitted). WHAT DOES NOT EXIST HERE: NO school impact fees — the 2021 TischlerBise report states verbatim, repeatedly, 'Per City of Post Falls policy, impact fees are not charged for public schools or public charter schools.' No standalone library/drainage/open-space/affordable-housing/general-government impact fee (Public Safety covers police). No standalone mitigation fee schedule. CAVEATS / CONFIDENCE: (1) The currently published per-unit impact fees ($6,721 parks SF etc.) exceed the 2021 TischlerBise study's max-allowable figures (Parks $3,721, Public Safety $452, Streets $1,510, Multimodal $869 SF) — confirmed by independently reading the 2021 study PDF. The published schedule reflects the City's adopted/escalated amounts plus the separately-collected Fire/EMS. (2) The City was in Phase II of an impact-fee update study as of May 14, 2025 (confirmed via Coeur d'Alene Press) — figures may change; verify the latest adopted resolution before relying on them. (3) The legacy postfallsidaho.org domain that hosted an impact-fee summary page is being phased out; figures here were verified against the live official postfalls.gov Fee Schedule PDF. VERIFY: confirmed 17 of 17 rows; dropped 0. CORRECTIONS MADE: (a) Re-attributed all 11 impact-fee rows from sourceIndex 2 (2021 TischlerBise study) to sourceIndex 0 (official Fee Schedule PDF), because the amounts appear VERBATIM in the official adopted Fee Schedule but do NOT match the 2021 study (which shows different max-allowable figures) — the researcher's original sourceQuotes referencing source 2 were not present in source 2. Updated all impact-fee sourceQuotes to the verbatim IMPACT FEES table text. (b) Raised confidence on the 3 Fire/EMS rows from medium to high, since they are explicit line items in the adopted Fee Schedule IMPACT FEES table rather than inferred from fund accounting. (c) Removed two non-load-bearing sources (sourceIndex 2 'Fee Schedule public hearing page' and sourceIndex 3 Citizen Portal news article) and renumbered remaining sources; the dead/redirected postfallsidaho.org reference was dropped from the source list. excludeFromTotal corrections: none needed — the 1\" Commercial water meter variant and the 1\" Typical Dig In install charge were both already correctly marked excludeFromTotal=true; verified the representative SF total (impact $14,221 + water $3,278 + sewer $7,621 + $5 hookup) does not double-count meter sizes or install charges.
All amounts are in current US dollars per the City of Post Falls Fee Schedule effective October 1, 2025 (FY2026), confirmed verbatim against the official Fee Schedule PDF (Revised 10-1-2025). Impact fees are assessed per housing unit and collected at building-permit issuance. Representative single-family total impact fee = $14,221/unit; representative multifamily = $10,370/unit. Add water capitalization ($3,278, 3/4\"-1\" residential), sewer capitalization ($7,621/service unit), and $5 sewer hookup for the typical new single-family connection. Excluded rows are mutually-exclusive meter sizes or physical service-installation/deposit charges, not capacity/impact fees.
