Modular homes in Florida.
What property owners should know.

Planning & permits · Off site construction

Modular construction is becoming a more practical option for Florida property owners looking for a faster and more controlled way to build a new home.

Instead of constructing the entire house outdoors at the property, major portions of a modular home are manufactured in a controlled facility, transported to the site and assembled on a permanent foundation. Site work, utilities, foundations, exterior connections and final completion are coordinated locally.

Florida’s 2026 legislation creates stronger protections for qualifying off site constructed homes. Effective July 1, 2026, House Bill 803 established section 553.385, Florida Statutes, requiring qualifying off site constructed residential dwellings to be allowed in zoning districts where detached single family homes are permitted. Local governments generally may not regulate these homes more restrictively merely because portions were built somewhere other than the final property. (Florida Senate)

This does not mean that an owner can purchase any factory built structure and place it on any lot. The property, dwelling, foundation and complete project must still satisfy applicable zoning, building, floodplain, wind, utility and site development requirements.

What Is a Modular Home in Florida?

Florida law generally uses the terms manufactured building, modular building and factory built building for structures or building assemblies manufactured at a facility and later installed or erected as a finished building. Or as part of one.

A Florida modular building may incorporate structural, electrical, plumbing, heating, ventilation and other building systems before it reaches the site. Modular buildings are constructed under the Florida Building Code and are subject to the state’s Manufactured Building Program. (Florida Senate)

A modular home is not simply a portable home, trailer or temporary building. A residential modular home is typically:

• Designed for permanent residential use
• Constructed to the Florida Building Code
• Installed on a permanent, site specific foundation
• Connected to permanent utilities
• Treated as real property
• Completed under local permits and inspections for the on site portions of the work

Modular Home vs. Manufactured Home: Why the Difference Matters

The terms “modular home” and “manufactured home” are frequently used interchangeably in advertisements, but they do not always mean the same thing under Florida law.

Florida modular homes

A modular home is built under the Florida Building Code. It is normally installed on a permanent foundation designed for that dwelling and property.

HUD manufactured homes

A manufactured home. Often still called a mobile home. Is constructed under the federal Manufactured Home Construction and Safety Standards administered by the U.S. Department of Housing and Urban Development. It normally bears a federal HUD label.

Florida’s own guidance explains that both types may be constructed in factories, but modular homes are built under the Florida Building Code while manufactured or mobile homes are built under federal HUD standards. (Florida Building Code)

The distinction can affect:

• Foundation design
• Installation requirements
• State approval markings
• Local permitting
• Contractor qualifications
• Financing
• Insurance
• Appraisal
• Property taxation
• Future resale

Before signing a purchase agreement, an owner should obtain written confirmation of exactly how the dwelling is classified.

What Florida’s New Law Changes

Florida’s new law creates what is commonly called zoning parity for qualifying off site constructed homes.

Off site homes must be permitted in single family districts

Section 553.385 provides that an off site constructed residential dwelling must be permitted as of right in a zoning district where detached single family homes are allowed.

This means a county or municipality generally cannot exclude an otherwise qualifying home solely because it was constructed wholly or partially off site.

Local governments cannot apply more restrictive treatment

A local government may not adopt or enforce a zoning, land use or development regulation that treats a qualifying off site dwelling differently or more restrictively than a site built single family dwelling allowed in the same district.

For example, a jurisdiction should not impose a separate zoning prohibition simply because a dwelling consists of factory built modules.

Equal architectural standards can still apply

The law does not eliminate local design regulations.

Counties and municipalities may continue applying generally applicable standards concerning:

• Architecture
• Exterior appearance
• Design
• Setbacks
• Building height
• Building bulk

The important requirement is that those standards must also apply to comparable site built homes in the same zoning district.

Compatibility standards are limited

The law allows local governments to regulate certain features, including:

• Roof pitch
• Livable square footage
• Exterior finishing materials
• Foundation enclosure
• Attached structures
• Building setbacks
• Lot dimensions
• Orientation of the home on the lot

These standards may not be used as a disguised method of excluding modular or other qualifying off site homes.

“Permitted as of Right” Does Not Mean “No Permit Required”

This is one of the most important distinctions for property owners.

The phrase permitted as of right means the construction method cannot, by itself, be used as a reason to prohibit the home in a zoning district that allows detached single family houses.

It does not mean:

• No building permit is required
• No zoning review is required
• The foundation can be installed without engineering
• Floodplain rules do not apply
• The home is exempt from wind load requirements
• Utilities can be connected without permits
• An HOA must approve the design
• Any model may be installed on any property

The state approval of the factory built portion and the local approval of the property specific work are related but separate parts of the project.

State Approval vs. Local Approval

A modular project typically has two regulatory components.

State regulated factory construction

The manufactured portions of the building are constructed from state approved plans and inspected through the Florida Manufactured Building Program or an approved inspection agency.

Approved modular buildings bear a DBPR insignia. The insignia commonly identifies the manufacturer, inspection agency, plan tracking number, occupancy, number of modules and date of manufacture. (My Florida License)

Locally regulated site work

The local building department remains responsible for property specific construction and installation, which can include:

• Foundation and footings
• Module attachment and assembly
• Site grading
• Drainage
• Water and sewer connections
• Septic or well systems
• Electrical service
• Driveways
• Garages
• Porches
• Decks
• Exterior stairs
• Final inspections
• Certificate of occupancy

DBPR guidance explains that state approved modular plans are generally exempt from duplicate local plan review for the factory built portion, but erection, assembly and on site construction remain subject to local permitting and inspection. (My Florida License)

Florida Specific Design Issues

A home designed for another state should not automatically be assumed acceptable for installation in Florida.

The project team must account for the actual property conditions, including:

Wind design

The dwelling, foundation, connections and attached structures must be designed for applicable Florida wind conditions.

Properties in Broward and Miami-Dade Counties are within Florida’s High Velocity Hurricane Zone and are subject to additional wind resistance requirements. (Florida Senate)

Floodplain requirements

A modular home on a flood hazard property may require:

• A specific finished floor elevation
• An elevated foundation
• Flood resistant materials
• Foundation openings
• Equipment elevation
• Special grading or drainage
• Floodplain development approval

These requirements depend on the property, flood designation and local regulations.

Soil and foundation conditions

The foundation is not simply a standard accessory sold with the house. It should be designed for:

• The specific modular unit
• Soil bearing conditions
• Wind uplift
• Lateral forces
• Flood conditions
• Finished floor elevation
• Utility routing
• Site drainage

Transportation and crane access

A property may be legally buildable but operationally difficult for modular construction.

The project team should evaluate:

• Road width
• Overhead wires
• Bridges and weight restrictions
• Turning radius
• Tree clearance
• Staging space
• Crane location
• Neighboring properties
• Police or traffic control requirements
• Module dimensions
• Delivery sequencing

These conditions can materially affect cost and schedule.

A Step by Step Process for Florida Property Owners

Step 1: Complete property due diligence

Before choosing a home model, confirm:

• Zoning district
• Future land use designation
• Whether detached single family homes are allowed
• Setbacks
• Maximum building height
• Lot coverage
• Minimum home size
• Easements
• Flood zone
• Utility availability
• HOA restrictions
• Historic or architectural overlays

The home should be selected to fit the property. Not the other way around.

Step 2: Confirm the legal classification of the home

Ask the manufacturer to state in writing whether the product is:

• A Florida modular or manufactured building
• A HUD manufactured home
• A panelized building
• A kit or pre cut home
• Another prefabricated system

Also request the code edition, state approval information and applicable inspection documentation.

Step 3: Verify the manufacturer, plan and insignia

Request:

• Manufacturer’s legal name
• Florida certification information
• Approved plan number
• Plan tracking number
• DBPR insignia information
• Approved inspection agency
• Design wind criteria
• Module serial numbers
• Construction specifications

Florida’s Building Code Information System allows users to search approved modular plans, organizations and insignias. (Florida Building Code)

Step 4: Engage the Florida project team

Depending on the project, the owner may need:

• Licensed general or building contractor
• Florida architect
• Structural engineer
• Civil engineer
• Surveyor
• Geotechnical engineer
• Modular manufacturer
• Transportation contractor
• Crane contractor
• Utility contractors

Responsibilities should be clearly assigned before permitting begins.

Step 5: Develop the site specific plans

The permit package may need to address:

• Site plan
• Foundation
• Module attachment
• Finished floor elevation
• Drainage
• Utility services
• Exterior stairs
• Porches and garages
• Driveway
• Landscaping
• Energy documentation
• Fire separation
• Product approvals

Step 6: Confirm the complete project budget

The advertised price of the modular home is rarely the complete project price.

A realistic budget should evaluate:

• Land
• Surveys
• Design and engineering
• Permit and impact fees
• Site clearing
• Earthwork
• Foundation
• Utility connections
• Transportation
• Crane and setting
• Module assembly
• Roofing and exterior tie ins
• Interior finish connections
• Driveway and drainage
• Landscaping
• Temporary services
• Insurance
• Financing costs
• Contingency

Step 7: Coordinate manufacturing and site construction

The project schedule should coordinate factory production with:

• Permit approval
• Foundation completion
• Utility preparation
• Site access
• Crane scheduling
• Delivery permits
• Weather
• Inspections

Producing the house before the property is ready can result in storage, transportation and delay costs.

Step 8: Complete inspections and closeout

Final occupancy may require confirmation of:

• Foundation approval
• Module connections
• Trade connections
• Site drainage
• Exterior completion
• Life safety systems
• Addressing
• Utility authorization
• Final survey or elevation certificate
• Certificate of occupancy

Questions to Ask a Modular Home Company

Before paying a deposit, ask:

1. Is this a Florida Building Code modular home or a HUD manufactured home?
2. Is your company currently certified to manufacture homes for Florida?
3. Is this exact plan approved for use in Florida?
4. What wind design criteria are included?
5. Is the home designed for Broward or Miami-Dade HVHZ requirements, when applicable?
6. Who designs the foundation?
7. Who obtains local permits?
8. Who provides transportation and crane services?
9. Who connects the modules and utilities?
10. What work is excluded from the advertised price?
11. Who is responsible for damage during transportation or setting?
12. What warranties apply to factory work, transportation and site work?
13. When does title and risk of loss transfer?
14. What happens if local approval requires design changes?
15. Is financing contingent on appraisal and final insurability?

Does the Law Override an HOA?

No.

Section 553.385 regulates counties and municipalities. It does not eliminate private deed restrictions, homeowners’ association rules or architectural review requirements.

An HOA may still review matters such as exterior materials, roof shape, color, landscaping and architectural appearance, subject to the association’s governing documents and other applicable law.

Owners should investigate HOA approval before ordering a home.

Can a Local Government Still Deny a Modular Home?

A local government may still deny a proposal that does not comply with legitimate requirements involving:

• The permitted residential use
• Setbacks
• Height
• Lot dimensions
• Building Code compliance
• Floodplain development
• Foundation design
• Utilities
• Drainage
• Fire access
• Site development

What the local government generally cannot do is deny an otherwise qualifying home solely because it was constructed off site.

Is Modular Construction Automatically Cheaper?

Not always.

Factory construction can reduce certain weather delays, improve production consistency and allow site work to occur while the home is being manufactured. But savings can be reduced by:

• Long distance transportation
• Crane access
• Specialized engineering
• Difficult foundations
• Flood elevation
• Restricted sites
• Utility extensions
• High end customization
• Manufacturer change orders
• Site coordination problems

Owners should compare complete, installed project costs rather than comparing the price of a modular shell with the price of a completed site built home.

Final Takeaway

Florida’s new law removes an important barrier by preventing local governments from excluding qualifying off site constructed homes simply because of their construction method.

It does not eliminate the need for professional planning.

A successful Florida modular home project still depends on selecting the right property, confirming the dwelling’s legal classification, using an approved manufacturer, designing the foundation for the actual site, coordinating local permits and accurately budgeting every part of the work.
