    Clay County
    UNCONFIRMED — amount is the SUPERSEDED 2025 rate. MULTI-DISTRICT FEE: unincorporated Clay spans all five mobility districts and the rate varies enormously by district. Default shown is the Branan Field & Oakleaf district (the county's largest unincorporated urban/nonresidential growth area). Schedule row ITE 820 Retail Shopping Center, 2025 schedule (Post 10/1/2025), per 1,000 sq ft GFA. Other districts, same row (2025): Lake Asbury & Green Cove Springs $20,131; Middleburg & West Clay $9,082; Orange Park/Lakeside/Fleming Island $3,162; Keystone Heights & South Clay $2,250. AUDIT 2026-07-12: (1) APPLICABILITY CONFIRMED from the ordinance text — Mobility Fee Ordinance Sec. 2.01.A (Imposition) and Sec. 3.06 (Applicability) both limit the fee to New Construction 'within the unincorporated area of the County'. There is no interlocal or municipal opt-in provision, so this fee applies ONLY here, not in Clay's four municipalities (their county-mobility records were corrected to $0 on this audit). (2) STEP-UP CADENCE: Sec. 3.10.A — 'On June 15, 2026 and on each June 15 thereafter up to June 15, 2029, the Mobility Fees shall automatically be adjusted as set forth in the Mobility Fee rate schedules attached as Appendix C.' Next step-up: 6/15/2027. (3) The five 2026 district rate-schedule PDFs were re-fetched 7/12/2026 and remain IMAGE-ONLY with no text layer (web fetch returns 'no machine-readable text'; Chrome PDF plugin and Google Docs viewer both previously failed).

How impact fees work in Florida

Florida impact fees are one-time charges on new development, governed by Section 163.31801, Florida Statutes (the Florida Impact Fee Act). The statute requires fees to be based on the most recent and localized data, spent on the infrastructure category they were collected for, and adopted by ordinance.

Since 2021, the law also limits how fast fees can rise: increases up to 25% phase in over two years, increases of 25–50% phase in over four years, and increases above 50% are allowed only with a demonstrated extraordinary-circumstances study and at least a two-thirds vote of the governing body.

Counties and cities can both levy impact fees. Inside an incorporated city, a project typically pays the county's countywide fees plus any municipal fees the city has adopted, which is why totals differ between a city and the unincorporated county around it.
