Coverage & caveats
All residential impact and connection fees were taken from the official "Lehi City Connection and Impact Fees, Updated March 2, 2026" PDF hosted on lehi-ut.gov — the city's current authoritative schedule. Most categories carry a "FY 2020 Fee Amount" header, meaning Lehi has not escalated these impact-fee amounts since its FY2020 impact fee analysis; they remain the rates in force per the March 2026 document. CATEGORIES FOUND (residential, per dwelling unit unless noted): Transportation/roads ($1,163 SFD / $708 MF), Parks & Recreation ($2,772.98 SFD / $2,415.41 MF), Fire/EMT ($198.02 SFD / $81.98 MF), Police ($98.35 SFD / $117.03 MF), Culinary Water impact ($1,194.07 at 3/4" residential meter) plus a water CONNECTION fee ($425.62 at 3/4"), Local Lehi Sewer impact ($872.44 at 3/4" residential), Storm Drain ($1,391.00 per acre, all uses — billed per acre not per unit), and Pressurized (secondary) Irrigation impact ($5,609.36 per acre residential, 0.25-acre minimum) with a PI connection fee ($541.66 at 1" meter). Lehi is a municipal electric utility, so an Electric Power connection fee ($374.02 residential up to 200A) and a Power Impact Fee (FY2026: $2,554 for a 200A single-phase residential service) also apply to new homes. SEPARATE DISTRICT: Timpanogos Special Service District (regional sewer treatment plant) charges a sewer impact fee of $5,793.00 per single-family house / per dwelling unit (FY 2026). This is collected on top of Lehi's own local sewer impact fee of $872.44 and is paid by a builder in Lehi — attributed in that row's notes. WHAT DOES NOT EXIST HERE: NO SCHOOL IMPACT FEE — Utah law does not authorize school impact fees (schools are funded via property tax by Alpine School District / its successor districts, not impact fees). No library, no open space, no affordable housing, and no general/capital or mitigation impact fee line items appear on Lehi's schedule. Sewer, storm drain, transportation, parks, fire, police, and Timpanogos sewer have "Connection Fee: Not Applicable" — only an impact fee applies; water, pressurized irrigation, and electric power have BOTH a connection fee and an impact fee. ADU CAVEAT: Per Utah HB 462 (2022), Lehi can no longer collect impact fees on INTERNAL accessory dwelling units (e.g., basement apartments). No separate ADU impact-fee row is published; an internal ADU is impact-fee-exempt by statute. Detached ADUs may be treated as additional dwelling units — not separately published, so omitted. NORMALIZATION: Water and local sewer impact fees are tiered by meter size; the residential base 3/4" meter is used as the primary per_dwelling_unit row, with larger meter sizes (non-residential) omitted. Single-family detached is primary; multifamily per-unit rows are included as additive same-category alternatives (not excluded, since a project is one OR the other — multifamily rows are marked excludeFromTotal=true so a single-family total is not double-counted). Storm drain and pressurized irrigation are assessed per acre, not per unit, so they are included with excludeFromTotal=true and a note (a typical ~0.2-0.25 acre SFD lot would pay roughly the 0.25-acre minimum). Power impact fee for a representative 200A residential service shown. CONFIDENCE: High for all rows — exact verbatim quotes from the current official March 2, 2026 city document. Population is the 2024 Census ACS 5-yr estimate (~85,173); the city is growing fast (2026 projections ~96k-102k).
Lehi impact fees are largely held at FY2020 amounts per the March 2, 2026 schedule. A representative new single-family detached home in Lehi pays, at minimum, the following ADDITIVE impact fees (per dwelling unit): Transportation $1,163.00 + Parks & Rec $2,772.98 + Fire/EMT $198.02 + Police $98.35 + Culinary Water impact $1,194.07 + Local Lehi Sewer impact $872.44 + Timpanogos SSD regional sewer $5,793.00 = $12,091.86 in per-unit impact fees, PLUS per-acre Storm Drain ($1,391.00/acre, 0.25-acre min) and Pressurized Irrigation ($5,609.36/acre, 0.25-acre min), PLUS connection fees (water $425.62, PI $541.66, electric $374.02) and an electric Power Impact Fee (~$2,554 for 200A). Exact totals depend on lot size and meter/service sizing. Multifamily figures are per-unit and shown separately.
