Caldwell, ID Development Impact Fees (2026)

Caldwell, ID residential development fees verified from official adopted City of Caldwell resolutions (all PDFs were scanned images requiring OCR; key residential figures were additionally confirmed by direct visual inspection of the rendered fee tables).

What exists

1) IMPACT FEES (Idaho Code 67-82 "Development Impact Fee Act"): Caldwell levies Parks, Fire, and Police impact fees. Currently adopted amounts are from Resolution 193-23, effective Oct 1, 2023: Parks $2,081.73/unit, Fire $1,070.37/unit, Police $184.01/unit (residential total $3,336.11/unit). These are flat per-dwelling-unit fees (not size-tiered). A May 15, 2007 vesting cutoff applies: lots occupied prior to that date are exempt; all new construction pays full impact fees. NOTE on the pending update: a 2025 Police & Fire impact-fee study (planning case CPM25-000001/ZOA25-000002) proposes RECALCULATED maximum-supportable fees but it is NOT yet adopted; the Res 193-23 figures remain in effect. I report the adopted (Res 193-23) figures as the current fees. 2) TRANSPORTATION/TRAFFIC IMPACT FEE: NEW. Caldwell adopted the Caldwell Area CIP & Traffic Impact Fee Program (Resolution 429-24, passed Jan 21, 2025) jointly with HIGHWAY DISTRICT NO. 4 (HD4). This is the separate-district transportation impact fee that a Caldwell residential builder must pay; it is administered jointly by the City of Caldwell and HD4 for the CATS service area, and fees collected by the City are spent only on CIP projects within the City of Caldwell. Table 7 fee schedule (confirmed by OCR/visual inspection of the rendered table on PDF page 33): Single-Family $4,226/unit, Multifamily Low-Rise $2,293/unit, Multifamily Mid-Rise $1,753/unit, Mobile Home $2,607/unit, ADU $1,394/unit. (Note: HD4's SEPARATE "Mid-Star" service area TIF applies to unincorporated Canyon County, NOT to the City of Caldwell, and is excluded.) 3) WATER CONNECTION FEES (Resolution 318-24, eff. Oct 1, 2024): For a single-family residence connecting to City water, the ADDITIVE components are Well Development Fee $898.64/unit + Trunk Line Fee $735.35/unit + Water Connection charge (3/4"x3/4" meter & service) $2,617.03/ea. A frontage-based Water Main Extension Fee of $39.75/ft (min $2,385 at 60 ft) may also apply when a new main is needed; included as a separate row but excluded from a simple per-unit total because it is frontage/situation-dependent and often waived when developer installs mains. Larger meter sizes (1" $3,864.89; 1.5" $5,578.21; 2" $7,170.21) are mutually-exclusive alternatives (excluded). Connection fees were increased ~50%/yr in FY2024-2026 per the Water Facilities Plan (confirmed in the resolution cover memo). 4) SEWER CONNECTION FEES (Resolution 316-24, eff. Oct 1, 2024): For a single-family residence, the ADDITIVE components are Interceptor Fee $1,170.93/unit + Plant Capacity Fee $1,213.30/connection (these two sum to the stated $2,384.23 residential minimum, confirmed verbatim in the resolution). A frontage-based Sewer Main Extension Fee of $42.38/ft (min $2,542.80 at 60 ft) may apply (separate row, excluded from per-unit total, frontage-dependent/often waived). A Stub-out Fee of $977.18 applies ONLY if the City elects to construct the service stub (conditional; excluded).

What does not exist here

- NO SCHOOL IMPACT FEE: Idaho state law (Idaho Code 67-82) does not authorize school impact fees; none is levied. - No drainage/stormwater impact fee, no library impact fee, no open-space/affordable-housing/general-capital impact fee identified - Caldwell's impact fees are limited to Parks, Fire, Police, and (new) Transportation. - Building/electrical/plumbing/mechanical PERMIT fees (Res 320-24) exist but are regulatory permit fees, not development impact/connection fees, so they are omitted per scope.

Key caveats

(a) All four city fee resolutions were scanned-image PDFs (no text layer); the independent verifier re-downloaded each PDF (Akamai bot-protection required full browser headers) and re-OCR'd them with tesseract at 300-400 dpi, confirming every dollar figure and quote. (b) The traffic impact fee is brand-new (Jan 2025 adoption); the underlying plan document still listed traffic fees as "currently HD4 and Nampa only" on an earlier page, reflecting timing before Caldwell's adoption - Table 7 itself lists Caldwell's adopted figures and KIVI-TV reporting confirms the council approved the program ("Growth has to pay for itself"; "different impact fees will be associated with single-family homes, multi-family housing, or shopping centers"). The KIVI article does not cite specific dollar amounts or HD4 by name. (c) Impact fees (Parks/Fire/Police) may be index-adjusted annually; the most recent ADOPTED schedule located is Res 193-23 (FY2024, eff. 10/1/2023); a newer index-adjusted resolution may exist but was not located, so confidence on currency is medium for those three rows.

CORRECTION TO NARRATIVE ONLY (no fee row affected): the researcher's coverageNotes claimed the 2025 draft study proposes SUBSTANTIALLY LOWER fees (draft Parks $951 / Fire $649 / Police $97 = $1,697). On re-inspection of source 5 (the Police & Fire CIP & Impact Fee Amendment study, CPM25-000001/ZOA25-000002), those specific numbers do NOT appear; the document's Figure 6 ("Summary of Maximum Supportable Development Impact Fees by Land Use") shows Single Family Police $641 + Fire $1,264 = $1,905 maximum supportable vs current $1,254 - i.e., an INCREASE of $651, and the study covers only Police and Fire (not Parks). The researcher's draft-figure characterization (direction and amounts) was inaccurate and has been removed; this does not change any adopted fee row, since all fee[] entries are sourced to the adopted Res 193-23, not the draft.
