Coverage & caveats
Source is the OFFICIAL current "Town of Gilbert Development Services Fee Schedules" (Revised 7/1/2025), downloaded from gilbertaz.gov (showdocument id=5883). It contains both the System Development Fees (SDF) table and the Water System/Resource/Wastewater Connection Fees table. SDFs were adopted by Council April 16, 2024 and are effective July 1, 2024 (AZ SDFs do not auto-escalate; 5-year study cycle). WHAT EXISTS (residential SDFs, per ARS 9-463.05): Parks & Recreation, Traffic Signals, Roads, Police, Fire. Traffic Signals and Roads are SEPARATE additive transportation components — both are included (sum = transportation). Total residential SDF for a single (detached) unit = $9,358 + $1,754 + $3,010 + $1,138 + $1,447 = $16,707. For a multifamily unit (2+ units per structure) = $6,016 + $1,253 + $2,149 + $732 + $930 = $11,080. CONNECTION/CAPACITY FEES (utility SDF-equivalent, charged by water meter size; base residential = 3/4"): three ADDITIVE components — Water Resource, Water Infrastructure (Water Infrastructure capacity), and Wastewater. These differ by SERVICE AREA. Gilbert has two mutually-exclusive areas: Neely (Wastewater $4,260) and Greenfield (Wastewater $4,467). Water Resource ($5,826) and Water Infrastructure ($8,310) are identical in both areas. I used the GREENFIELD service area as the primary representative (higher wastewater) and marked the Neely wastewater variant excludeFromTotal=true. Greenfield 3/4" connection total = $18,603 (Neely = $18,396). Larger meter tiers (1.0", 1.5", 2.0") are included as excluded variants for reference. WHAT DOES NOT EXIST in Gilbert: NO school impact fee (not an authorized category under Arizona law). NO separate library SDF, NO general-government/capital SDF, NO drainage/stormwater SDF, NO open-space SDF, NO affordable-housing/inclusionary fee, NO standalone mitigation fee in the published schedule. (Library and general government are not listed in Gilbert's SDF table — only Parks & Rec, Traffic Signals, Roads, Police, Fire.) ADU: no separate ADU SDF tier is published; an ADU would be treated under the residential SDF / connection-fee structure (no dedicated figure to report). CAVEATS: gilbertaz.gov is behind Akamai bot protection (curl/WebFetch returned HTTP 403 "Access Denied" until full browser headers were supplied; the document then downloaded cleanly as a valid PDF). News reports (AZBEX, Gilbert Sun News) referenced a higher ~$20,220 figure from a Dec 2023 PROPOSAL that bundled additional utility components; the ADOPTED schedule figures above are the governing numbers. Special sewer assessments (Rawhide Park $2,852/connection; Gilbert Homes - contact Finance) apply only to specific subdivisions and are not town-wide. Sewer/Water "Buy-In" fees are calculated per project (no flat figure). All figures verified 2026-06-16. VERIFY: Independently re-fetched the primary source PDF (showdocument id=5883, Revised 7/1/2025) on 2026-06-17 using full Chrome browser headers + referer (curl) — the initial bare-curl attempt returned the Akamai "Access Denied" HTML page; the headered request downloaded a valid 636 KB PDF v1.6. Extracted with pdftotext -layout. Confirmed the SYSTEM DEVELOPMENT FEES table (column order in source: Parks and Recreation, Traffic Signals, Roads, Police, Fire): Single Unit 9,358 / 1,754 / 3,010 / 1,138 / 1,447 and 2+ Units per Structure 6,016 / 1,253 / 2,149 / 732 / 930 — all amounts match exactly. Confirmed the WATER SYSTEM, RESOURCE AND WASTEWATER CONNECTION FEES table: Neely 3/4" = 5,826 / 8,310 / 4,260 (TOTAL 18,396); Greenfield 3/4" = 5,826 / 8,310 / 4,467 (TOTAL 18,603); 1.00" = 9,729 / 13,878 (sum 23,607) — all match. Arithmetic re-checked: SF SDF sum = 16,707, Greenfield connection sum = 18,603 (equals source TOTAL column), Neely sum = 18,396 (equals source TOTAL). Note: source column order is Parks/Traffic Signals/Roads/Police/Fire, so individual sourceQuote strings (e.g. "Single Unit Roads $3,010") are not literal contiguous substrings of the table layout, but every dollar amount maps unambiguously to its correct category in the source, so confidence retained at high. Secondary reference URLs (SDF webpage; Municode Ch.10 Art.XI) return HTTP 200 with browser headers (403 only under default fetch UA) — live, but they carry no fee rows. confirmed 16 of 16 rows; dropped 0; excludeFromTotal corrections: none — Neely wastewater variant, all five multifamily rows, and the 1.0" meter variant remain correctly flagged excludeFromTotal=true (mutually-exclusive service area / different land use / larger meter tier); no double-counting in the representative single-family + 3/4" Greenfield total.
All SDF figures are per dwelling unit from the adopted SDF table (effective 7/1/2024). Connection fees are per 3/4" residential water meter (Greenfield service area used as primary; Neely as excluded variant). Transportation = Roads + Traffic Signals (two additive rows). Water connection = Water Resource + Water Infrastructure (two additive rows) + Wastewater.
