Coverage & caveats
Source of truth is St. Johns County's consolidated "Master Impact Fee Schedule" — Phase 1 2026, effective March 4, 2026 (the schedule currently in effect as of 2026-06-16; adopted by ordinance approved 12/2/2025). St. Johns County is a single point of collection for ALL county residential impact fees: Roads (renamed Multimodal Transportation), Schools, Public Buildings/General Capital, Fire Rescue, Law Enforcement & Jail, Parks, and a NEW Conservation/Open Space fee (phasing in: starts at 50% of max, +12.5%/yr for 4 yrs to full amount). The county impact fee is TIERED BY HOME SIZE (sq ft), NOT a flat per-unit amount. PRIMARY single-family row = the 1,801-2,500 sq ft tier (a representative ~2,000-2,500 sq ft home), TOTAL $22,490/du. Other size tiers are included as excludeFromTotal=true reference rows. There is NO separate flat multifamily impact fee — multifamily (ITE LUC 220/221/222) uses the SAME size-tiered residential table; a typical apartment (801-1,250 sq ft) tier is included as the representative multifamily row (excludeFromTotal=true to avoid double-counting with the SFD primary rows). FLORIDA NOTE: unlike CA, Florida counties CAN and DO levy a school impact fee — St. Johns has a large one ($6,082 at the primary tier), collected by the County on behalf of the school district. WATER/SEWER: St. Johns County Utility Department (SJCUD) charges per-dwelling Unit Connection Fees — Water $2,850 and Sewer $5,750 (FY2025 tariff, June 17 2025) — these are ADDITIVE to each other and to the impact fees. SJCUD also charges tapping/installation fees (3/4" water tap $1,395; 2" sewer force-main tap $1,600) and a $75 locate fee per tap; these are physical installation charges, additive. CAVEAT: parts of the county (e.g., some northern areas) are served by JEA rather than SJCUD; JEA capacity fees ($4.68/gal water, $25.57/gal sewer of average daily flow, ~350/280 gpd for a single-family home) differ and a representative JEA water+sewer connection runs higher — builders in JEA's service territory pay JEA's schedule instead, not included as primary rows here. Categories that do NOT exist as separate county residential impact fees: drainage/stormwater (not a separate impact fee line), affordable housing (none — instead there is a WAIVER: 100% for <=50% AMI, 50% for 50-80% AMI, w/ 30-yr deed restriction), library (folded into Public Buildings, not a standalone line). Mitigation fees: none published as a flat residential impact fee. PRIMARY total of county impact fees + SJCUD water+sewer connection for a representative single-family home ~ $22,490 + $2,850 + $5,750 = $31,090 (before tapping fees). VERIFY: confirmed 16 of 16 rows; dropped 0. All seven primary 1,801-2,500 sq ft SFD impact-fee amounts (Roads $12,015 / Schools $6,082 / Public Bldgs $968 / Fire $764 / Law&Jail $452 / Parks $1,906 / Consv $303, TOTAL $22,490) verified exactly against the Phase 1 2026 Master Impact Fee Schedule PDF (source 0). All three reference tiers (1,251-1,800 TOTAL $17,811; 2,501-3,750 TOTAL $27,514; 801-1,250 multifamily TOTAL $13,115) verified and correctly retained as excludeFromTotal=true (no double-count: primary SFD total includes only the 1,801-2,500 tier; reference tiers and the multifamily tier are mutually-exclusive alternatives correctly excluded). SJCUD Water UCF $2,850, Sewer UCF $5,750 (Schedule A, "Single or Multiple Family (per dwelling or per unit) ... 1.0000 ERC/EIC"), 3/4" water tap $1,395 (Schedule F(1)) and 2" force-main sewer tap $1,600 (Schedule F(2)) all verified against the FY2025 tariff (source 3); $75 locate fee confirmed. Conservation/Open Space fee phase-in (50% of max, +12.5%/yr x4) and the Multimodal Transportation / Law Enforcement & Correctional Facilities renames verified against the Dec 2, 2025 ordinance press release (source 2). excludeFromTotal corrections: none needed — all four mutually-exclusive variant rows were already correctly flagged. Minor fix: corrected the sewer-connection sourceQuote, which in the researcher output had garbled the table line; the $5,750 sewer UCF sits on the same "Single or Multiple Family ... 1.0000 ERC/EIC" line as the $2,850 water UCF in Schedule A.
All county impact-fee figures are from the Phase 1 2026 Master Impact Fee Schedule (effective 3/4/2026). "Roads" = Multimodal Transportation Impact Fee; "Law & Jail" = Law Enforcement & Correctional Facilities; "Consv." = Conservation/Open Space (new, phasing in). Public Buildings is the general/capital facilities category and also encompasses library facilities (no standalone library line). Water/sewer connection fees are SJCUD FY2025 per-dwelling Unit Connection Fees and are additive. Single-family detached and the size-tiered residential table also serve multifamily/townhome (ITE LUC 220/221/222) — only the home-size tier differs.
