Clay County, FL Building Safety: Fire Sprinkler Requirements (2026)

Section 6-109(d) exempts single-family detached residential dwellings from plan review under the county's fire prevention plan-review article altogether, unless the owner intends to install a fire sprinkler system, in which case application and review under that section become required for the sprinkler work specifically. For every other project, § 6-109(a) requires a complete set of plans, drawings and specifications submitted with the permit application for review and approval by the fire marshal before installation of a fire prevention system, and § 6-109(c) bars starting work on that system until the fire marshal approves it, backed by the fire marshal's authority to issue a stop-work order.

Because the county treats a voluntary residential sprinkler installation as something to encourage rather than tax, § 6-123(e)(3) sets the fire sprinkler system permit fee itself at no charge, even though the related plan-review fee schedule in § 6-123(a)(5)-(6) still charges $50 to $75 per system for plan review of fire sprinkler and standpipe systems generally, and § 6-123(c)(1) charges $75 for the hydrostatic test used to recertify a sprinkler system. Homes that do get a sprinkler system installed remain subject to the fire marshal's general enforcement and inspection authority under §§ 6-110 and 6-114, including the right to enter for inspection and to stop work found out of compliance with approved plans.
