Boxabl in Florida: DBPR Approval Status, Closed Construction Rules & PE Pathway (2026)

The Short Answer

As of 2026, Boxabl Casitas are not approved for installation in Florida under the state's Manufactured Buildings Program administered by the Department of Business and Professional Regulation (DBPR). You cannot simply order a Casita, place it on a slab, and receive a Certificate of Occupancy from a Florida building department.

There is one narrow alternative pathway under Florida Building Code Section 104.11, which allows building officials to accept engineered alternatives to prescribed code compliance methods. Whether your local jurisdiction will entertain that pathway for a closed-construction dwelling is a question only the local building official can answer — and the answer needs to come in writing before any meaningful engineering or unit procurement decisions get made.

Why Florida Treats Factory-Built Housing Differently

Florida has the most rigorous factory-built housing program in the United States, and it exists for a specific historical reason. After Hurricane Andrew flattened large portions of South Florida in 1992, the state consolidated its building regulations into a single Florida Building Code and built a parallel program for any structure that arrives from a factory in finished or partially finished form.

That program lives in Chapter 553, Part IV of the Florida Statutes, and it is enforced by DBPR through the Manufactured Buildings Program. The premise is simple: if a building or any portion of a building cannot be inspected on site because it was sealed shut at the factory, then the inspection has to happen at the factory instead, by a state-approved third-party agency working under DBPR oversight.

This is why Florida looks like an outlier on Boxabl's approval map. Boxabl has been approved in Arizona, California, Alaska, Hawaii, Kansas, Oklahoma, Oregon, Utah, Vermont, West Virginia, Wyoming, and New Mexico. Florida is conspicuously absent — and so is essentially every Gulf Coast and Atlantic state with hurricane exposure. The reason is not that Boxabl's product is structurally inadequate. The reason is that Florida requires a specific certification process for the building itself, separate from any approval the components might carry.

What "Closed Construction" Actually Means

The Florida Statutes define closed construction as any building, component, assembly, or system manufactured in such a manner that all portions cannot be readily inspected at the installation site without disassembly or destruction.

In practical terms, if a building shows up on a flatbed truck with finished walls, hidden electrical runs, sealed plumbing, factory-installed insulation, and a closed roof assembly — it is closed construction. A local Florida building inspector cannot pull back the drywall to verify rough-in work. They cannot pull insulation to check fastener spacing. They cannot lift the roof deck to look at trusses.

A Boxabl Casita is closed construction by design. The folding-panel system is the entire product premise. Walls, mechanicals, and insulation are sealed inside the panels before the unit leaves Las Vegas. The factory inspection is the only inspection that can verify the concealed work, which is precisely why Florida requires the factory inspection to happen under a DBPR-approved framework before the unit ships.

How the DBPR Insignia Process Works

To earn a DBPR insignia, a manufacturer must:

Once a unit bears the insignia, no additional approval is required from the local government. The insignia is the state's stamp that the building complies with the Florida Building Code. Local jurisdictions handle site work only (foundation, utility connections, site-installed components).

Boxabl has not completed this process for Florida. Until they do, the insignia is not available on a Boxabl unit, and a Florida building department has no legal mechanism to issue a Certificate of Occupancy on the dwelling.

Florida Product Approval Is Not the Same Thing

This is the most common point of confusion.

Florida Product Approval (FPA) covers individual building components — windows, doors, roofing assemblies, structural connectors, and wall panels. A manufacturer submits a product, the product is tested against Florida Building Code standards, and if it passes, the product receives a Florida Product Approval number.

The DBPR Manufactured Buildings insignia covers the assembled building. It is a different program with different requirements, different regulators within DBPR, and different statutory authority.

A few practical implications:

• •A Boxabl wall panel that carries a Florida Product Approval number does not legalize the assembled Boxabl Casita.
• •A Boxabl Casita with a DBPR insignia would still need its windows, doors, and roofing components to carry Florida Product Approvals or Miami-Dade NOAs if installed in the Wind-Borne Debris Region.
• •Earning Product Approvals on individual components is a useful step toward DBPR certification, but it does not substitute for it.

If someone tells you "Boxabl panels meet the Florida code," they are likely referring to component-level performance, not building-level certification. The two are not interchangeable.

The Site-Specific PE Approval Pathway (FBC 104.11)

The Florida Building Code includes a provision at Section 104.11 — "Alternative materials, design and methods of construction and equipment" — which gives building officials discretion to approve alternatives to prescribed code requirements when an engineered demonstration shows equivalent compliance.

In theory, this is the legal mechanism that would allow a Florida professional engineer to develop a site-specific compliance package for a Boxabl unit, demonstrate that the building meets the intent of the Florida Building Code, and submit it for the building official's acceptance. In practice, the limits of this pathway matter:

Section 104.11 is generally used for unique structural systems, novel materials, or non-prescriptive engineering solutions. It is not commonly used to bypass parallel certification programs. The Manufactured Buildings Program exists as the prescribed route for closed-construction dwellings, so a building official can reasonably take the position that 104.11 does not apply because the prescribed route is available — the manufacturer simply has not pursued it.

That said, some jurisdictions may entertain a site-specific PE submission that addresses foundation design with full anchorage calculations, wind continuous load path from unit to foundation, opening protection compliance for the wind-borne debris region, energy code compliance documentation, and structural verification of the panel system under local design wind pressures.

Whether the building official accepts this is a jurisdictional decision. There is no substitute for asking the question directly, in writing, before committing to the product.

The Right Order of Operations

Anyone considering a Boxabl project in Florida should run the steps in this exact order:

Owners and developers who skip steps 1 and 2 and order units first end up with stranded inventory and unrecoverable deposits. We have seen it happen.

Foundation Engineering for Coastal Florida

Assuming the local building department gives a written green light, the foundation engineering scope on a Boxabl unit in coastal Florida is driven by three things: wind speed, exposure category, and flood zone.

Wind speed: Most of the Florida Panhandle and Gulf Coast runs at approximately 140 mph basic wind speed for Risk Category II under ASCE 7-22. Panama City, Pensacola, Mexico Beach, and similar markets fall in this range. Sites within one mile of the Gulf mean high water line are Exposure D, which significantly increases design pressures.

Flood zone: Bay County, Walton County, Gulf County, and other coastal Florida jurisdictions have extensive AE and VE flood zones:

Foundation Engineering Cost Ranges

For a typical 360 sq ft Boxabl Casita in Florida, engineering fees on a repeat-prototype basis:

Geotechnical investigation is separate — generally $1,500 - $3,000 per site.

Before spending money on engineering or a unit, your first step should always be a conversation with your local Authority Having Jurisdiction (AHJ) — typically the county or city building department. Ask them directly whether they will accept a closed-construction dwelling without a DBPR insignia, and whether they are open to a site-specific PE compliance package under FBC 104.11. Get the answer in writing. A five-minute phone call to the AHJ can save you thousands of dollars and months of frustration. If the AHJ says no, you have your answer before any money is spent. If they say yes, you have a clear path forward and can engage an engineer with confidence.

Frequently Asked Questions

Can I install a Boxabl Casita in Florida right now? Not under the standard Manufactured Buildings Program, because Boxabl has not earned a DBPR insignia. The only potential pathway is a site-specific PE approval under FBC 104.11, and only if your local building official agrees in writing to entertain that approach.

Is Boxabl approved in any Florida county? There is no county-by-county approval for closed-construction dwellings in Florida. Approval is a statewide DBPR determination. No individual county can substitute its own approval, although individual counties can accept FBC 104.11 alternatives at the building official's discretion.

What is the difference between Florida Product Approval and DBPR insignia? Florida Product Approval covers individual components such as windows, doors, and panels. The DBPR insignia covers the assembled building. A Product Approval on a component does not legalize a closed-construction building.

Can a Florida PE get my Boxabl approved through FBC 104.11? A Florida PE can prepare a site-specific compliance package and submit it, but the approval rests entirely with the local building official. Some jurisdictions will entertain this; many will not.

How much does foundation engineering cost for a Boxabl unit in Florida? Approximately $1,200 - $2,000 per unit in X or AE flood zones for slab-on-grade, and $3,500 - $6,000 per unit in VE zones for elevated pile or column foundations.

What wind speed applies in Panama City? Panama City sits at approximately 140 mph basic wind speed for Risk Category II under ASCE 7-22, with Exposure C inland and Exposure D within one mile of the Gulf mean high water line.
