Check the utility provider before you rely on thisUnincorporated Seminole is a utility patchwork. Seminole County Utilities, Sunshine Water Services, the Florida Governmental Utility Authority, four small associations, six cities, and an 84-square-mile area on wells and septic all serve parts of it. Entire unincorporated subdivisions in Sanford are on City of Sanford water and sewer and pay the county nothing — 28% of the total turning on the parcel's location.

Fees Seminole County does not charge
Verified absent, so you don't go looking for them.
No parks or recreation impact fee — the county's concurrency page lists parks as a facility but pointedly omits the marker for facilities that carry a fee.
No law enforcement, police or sheriff impact fee. No general government, public buildings or correctional impact fee.
No separate EMS impact fee — fire and EMS are one combined fee.
No stormwater or drainage impact fee, and no countywide stormwater utility fee.
No affordable-housing linkage fee and no residential art-in-public-places exaction.
No impact fee moratorium, suspension or reduction is in effect despite Seminole being built out.
What we could not verify
These are reported as gaps rather than estimated. The total above is a floor.
The ICC valuation dollars-per-square-foot is a non-county publication. The ~$143/sf figure is back-computed from two real 2024 permits, not read from a source.
Whether the fire, library and mobility square-footage tier uses heated or under-roof area is genuinely inconsistent in Seminole's own practice — about $1,030 of exposure. Real permits show both bases being applied to physically similar homes.
The FY 2026-27 solid waste assessment roll is not yet adopted
Non-county utility connection charges — Sanford, Casselberry, Sunshine Water Services, FGUA and others — are out of scope and materially different from county rates
Why this number is easy to get wrong
The county's Fee Summary page serves a superseded 2023 schedule, and separately hosts an unadopted 2014 draft with a blank resolution number and blank adoption date.
The posted schedules are headed '2020 Calculated', which reads exactly like a pre-adoption draft. It is not — rendering the scanned redline ordinances shows the old fees struck through and the Calculated table underlined as inserted, headed 'Adopted:'. Text extraction alone cannot tell you this.
Impact fees and water/sewer capacity fees are NOT due at permit issuance — they are deferred to before the pre-power electrical inspection. Cash-flow modeling that front-loads them is wrong.
The private-provider discount is 45% for inspections-only and 60% for plans plus inspections, and it is heavily used. Two physically identical homes differed by $902 for this reason alone, which silently deflates any comparable-permit sampling.
Permits applied for before mid-2021 are vested at the old rates — fire $172, library $54, and no mobility fee at all. Comparable sampling must screen for vesting.

How to use this. Every figure is transcribed from an official
Seminole County or Florida Statutes document, linked inline, with its effective date. No third-party
legal-code mirrors were used — in testing, one returned impact fees off by 2.4×. Built for screening
and pro-forma work; confirm with the county before you sign anything.
