Florida Code Reference
A plain-language map of the Florida building, fire, and administrative codes that govern relocatable classroom buildings — what they require, where each rule lives, and the numbers that matter most.
Florida school portables are governed by two parallel code systems, enforced by different officials. Almost every requirement traces back to one of these.
School buildings, including relocatables, are regulated under FBC §453, "State Requirements for Educational Facilities," inside the FBC (currently the 8th Edition, 2023). Relocatables specifically live in §453.27, "New Relocatable Buildings." This track covers design, construction type, structural/wind, foundations, egress doors, toilets, HVAC, interior finishes, and accessibility. It is enforced through the district's building code administrator / plan review process.
The Florida Fire Prevention Code (adopts NFPA 1 and NFPA 101 Life Safety Code) plus State Fire Marshal Rule 69A-58.0082, "Relocatable Buildings," govern separation, fire alarms, smoke/heat detection, egress to the outside, and emergency-vehicle access. This track is enforced by the local fire marshal / authority having jurisdiction (AHJ).
Department of Education Rule 6A-2.0010 (the "State Requirements for Educational Facilities," or SREF) sets the administrative program — when relocatables may be used, plan submittal, lease limits, inspections, and the 20-year facility-life accounting used for funding.
| Term | Meaning (as used in the codes) |
|---|---|
| Relocatable building | A building, or portion of a building, made of prefabricated units that can be disassembled and reassembled frequently — or a single unit of walls, roof and floor that is movable as a unit on wheels or by truck. (The everyday word is "portable.") |
| Cluster | A grouping of relocatable units sited together and treated as one group for separation, open-space, and fire-access purposes. |
| Factory-built / modular | A relocatable manufactured off-site under the DBPR Manufactured Buildings Program (Ch. 553, Part I) and carrying a state insignia rather than being field-inspected like site-built construction. |
The building-code requirements for a new school portable are organized into the subsections below. Titles reflect the FBC §453.27 series.
| Subsection | Subject | What it covers |
|---|---|---|
| 453.27.1 | Relocatables & shelter | Scope; when relocatables apply (K-12, college, ancillary); relationship to public-shelter requirements. |
| 453.27.2 | Design, plan approval, construction | Engineered design, plan review/approval, district-wide foundation plans, and DOT transport requirements. |
| 453.27.3 | Construction type | Permitted types of construction and materials. |
| 453.27.4 | Accessibility | Compliance with the FBC Accessibility code / ADA (ramps, platforms, routes). |
| 453.27.5 | Site standards | Floodplain considerations and separation of units on the site. |
| 453.27.6 | Structural | Wind loads, anchoring, and structural design (see §4 below). |
| 453.27.7 | Fire-retardant-treated wood | Where FRTW is required in relocatable construction. |
| 453.27.8 | Doors & platforms | Exit door specifications and roofed entry-platform requirements. |
| 453.27.10 | Interior finishes | Wall, ceiling, and toilet-room finish requirements. |
| 453.27.16 | HVAC | Air-conditioning, heating and ventilation systems. |
Subsection numbering follows the FBC §453.27 application matrix; consult the adopted code text for the exact language of each.
Under the 8th Edition (2023) FBC, structural design follows ASCE 7-22. Schools are typically Risk Category III or IV (higher design loads than ordinary buildings) because of the occupant load and, where applicable, their role as public shelters. Wind design uses the site's mapped ultimate design wind speed (FBC §1609), which varies by county and is highest in the High-Velocity Hurricane Zone (Miami-Dade & Broward).
§453.27.2).§453.27.8).This State Fire Marshal rule is the heart of the fire-safety requirements for portables. Key provisions:
| Situation | Requirement | Source |
|---|---|---|
| Portable/cluster to nearest permanent building or other cluster | ≥ 60 ft | 69A-58.0082 |
| Between individual units within a cluster | As approved by building official (site-specific) | FBC §453.27.5 / Ch. 553 F.S. |
| Threshold for independent fire alarm system | ≥ 60 ft from any other building | 69A-58.0082 |
| Fire-vehicle access to most remote unit (cluster) | Within 200 ft | 69A-58.0082 |
| Manual pull station from each egress door | Within 100 ft | 69A-58.0082 |
| Minimum overhead open space in a cluster | 50% of conditioned gross area | 69A-58.0082 |
Relocatable classrooms must comply with the Florida Building Code — Accessibility volume and the ADA (FBC §453.27.4). In practice this means an accessible route to the entrance, compliant ramps and landings (slope, width, handrails, edge protection), accessible door hardware and maneuvering clearances, and — where the unit contains a toilet — an accessible restroom. Because portables sit above grade, the entry ramp/platform design is usually the key accessibility item in plan review.
Relocatables built off-site as factory-built (modular) buildings fall under the DBPR Manufactured Buildings Program, Chapter 553, Part I, Florida Statutes. Such units are built and inspected to the FBC in the factory and carry a state insignia/label instead of being fully field-inspected.
| Item | Figure |
|---|---|
| Separation to permanent building / other cluster | 60 ft min |
| Independent fire-alarm threshold | 60 ft |
| Between units in a cluster | Local official (≈30 ft typical) |
| Fire access to most remote unit | Within 200 ft |
| Pull station to egress door | Within 100 ft |
| Cluster open overhead space | 50% of conditioned area |
| Exits — combustible classroom unit | 2 doors to outside |
| Emergency rescue opening trigger | Spaces for 6+ students |
| Facility life (funding) | 20 years |
| Nonbonded PECO lease limit | 3 years |
| Structural / wind standard | ASCE 7-22, Risk Cat. III–IV |
Because the binding numbers (spacing between units, wind design, anchoring) are site- and jurisdiction-specific, confirm with:
