Coverage & caveats
RESIDENTIAL development fees for Meridian, ID (Ada County). FOUND: (1) City development impact fees for Parks & Recreation, Police, and Fire — adopted via the 2019 Meridian Development Impact Fees study and indexed/adjusted effective 2/1/2023; fees are TIERED by square feet of climate-controlled (living) space, NOT a flat per-unit fee. Representative ~2,000-2,500 sq ft single-family home falls in the "1,701 to 2,500 sq ft" tier: Parks $4,119 + Police $402 + Fire $995 = $5,516 city impact total. Multifamily uses the SAME tier table based on average unit size (total building climate-controlled sq ft / number of units), so a typical small MF unit (e.g., 1,200 sq ft or less) = Parks $1,946 + Police $190 + Fire $470 = $2,606/unit. All other size tiers included as excludeFromTotal rows. (2) Water & sewer CONNECTION (Assessment) fees per Equivalent Residential Unit (ERU): Water $1,696/ERU, Wastewater/Sewer $5,807/ERU (current live City Fee Schedule, MMC 26-2566). (3) Water meter purchase fee for a standard 3/4" residential meter with single-port MXU radio = $422.37 (effective 3/5/2025) — this is in ADDITION to the water ERU assessment. (4) ACHD (Ada County Highway District) TRANSPORTATION impact fee is levied by the separate highway district and collected at the Meridian building permit: Single Family Detached $5,803, Duplex/Townhouse $3,182/unit, ADU $1,934 (Ordinance 254, effective 3/1/2026); multifamily/commercial requires individual ACHD assessment so not quantified. DOES NOT EXIST in Meridian: NO school impact fee (Idaho state law does not authorize school impact fees — school districts fund growth via bonds, not impact fees); NO general/capital, library, open space, affordable housing, or stormwater/drainage RESIDENTIAL impact fee (only commercial drainage PLAN-REVIEW fees exist, not a residential impact fee). CAVEATS: Both meridiancity.org and achdidaho.org block automated fetching (Cloudflare/Akamai 403); impact fee and assessment amounts were confirmed via the city's live City Fee Schedule web application (apps.meridiancity.org/CITYFEEWEB) and official city-hosted PDF handouts, which agree with each other. The current city impact fee schedule reflects the 2/1/2023 inflation adjustment to the 2019 study; no newer adopted schedule supersedes it as of 2026-06-16. ACHD multifamily transportation fee omitted because it is set by individual assessment, not a published per-unit figure.
Primary single-family rows use the 1,701-2,500 sq ft tier as the representative ~2,000-2,500 sq ft home. Other size tiers are included with excludeFromTotal=true. ACHD transportation fee attributed to the separate Ada County Highway District (collected at city permit). Water meter 3/4" total ($422.37) = base meter $186.42 + single-port MXU radio $235.95 (per FY25 handout effective 3/5/2025); it is additive to the water ERU assessment.
