Accessory Structures in Hialeah, FL: What Residents Actually Need to Know

If you live in Hialeah or are thinking about moving there, accessory structures are one of those things you probably won't think about until they affect you directly. Hialeah has 9 specific rules on the books covering different aspects of accessory structures, and some of them might surprise you.

Carport Rules

Hialeah requires building permits for carport construction. All carports must meet HVHZ hurricane wind load requirements and comply with zoning setbacks. Carports count toward lot coverage calculations. Front-yard carports may be restricted in certain residential districts. Metal and fabric canopy structures are subject to the same permit requirements.

Key details: Permit Required: Yes, all carports. HVHZ: Hurricane-rated required. Front Yard: May be restricted by zone. Lot Coverage: Counts toward maximum. Contact: (305) 556-8380 Building Dept.

Building a carport without a permit is a code violation subject to stop-work orders and retroactive permitting requirements. Non-HVHZ-compliant structures must be removed or brought into compliance. Fines apply under the administrative citation program. Contact Building Department at (305) 556-8380.

Tiny Homes

Tiny homes on permanent foundations in Hialeah must meet all Florida Building Code and HVHZ requirements, including minimum living standards. Tiny homes on wheels are classified as recreational vehicles and cannot be used as permanent dwellings. Hialeah's zoning code establishes minimum dwelling unit sizes that may exceed typical tiny home dimensions.

Key details: On Foundation: Must meet FL Building Code + HVHZ. On Wheels: Classified as RV, no permanent dwelling. Minimum Size: Zoning may require 750+ sq ft. Wind Rating: 170-200+ mph HVHZ design speed. Contact: (305) 556-8380 Building Dept.

Living in a THOW as a permanent residence violates the zoning code. Building an undersized dwelling without variance approval is a zoning violation. Unpermitted structures face stop-work orders and removal requirements. Contact Building Department at (305) 556-8380.

Compared to other cities, Hialeah takes a harder line on tiny homes. The enforcement and penalty structure reflects that.

ADU Rental Restrictions

ADUs rented long-term (30+ days) in Hialeah face no zoning-based restrictions beyond ordinary residential standards. Short-term rentals (under 30 days) fall under Florida Statute §509.032(7), which preempts outright local STR bans but allows registration and tax collection. Miami-Dade Tourist Development Tax 6% plus Florida state sales tax 6% = 12% combined transient tax.

Key details: Long-Term: Permitted, no city license. STR State Preemption: FL §509.032(7). Tourist Tax: 6% county + 6% state = 12%. DBPR License: Required (FL §509.241). Tenant Law: FL Ch. 83 Part II.

Failure to collect Tourist Development Tax: Miami-Dade Tax Collector enforcement plus state Department of Revenue penalties and interest. Operating without DBPR license: state administrative fines. Failure to comply with local registration: code enforcement citation.

ADU Impact Fees

Hialeah ADUs are subject to Miami-Dade County impact fees (roads, schools, parks, police, fire) tied to the new dwelling unit under Miami-Dade Code Chapter 33E, plus City of Hialeah building permit and plan-review fees. Florida Statute §163.31801 (Florida Impact Fee Act) caps annual increases.

Key details: County Code: Miami-Dade Chapter 33E. State Authority: FL §163.31801 (Impact Fee Act). Fee Categories: Roads, schools, parks, police, fire. Annual Cap: Inflation-adjusted (§163.31801(6)). City Fees: Hialeah Building Dept fee schedule.

Building permit will not issue without proof of impact fee payment. Construction without permits exposes the project to permit-after-the-fact at double fees, and the County may file a lien for unpaid impact fees against the parcel.

ADU Permits

Hialeah accessory dwelling units are permitted under the city's zoning code in single-family and multi-family districts, subject to lot-size, setback, and parking standards. The City of Hialeah Building Department issues permits under the Florida Building Code (FBC) HVHZ provisions. Florida HB 1031 (2024), codified at FL §163.31771, encourages municipalities to allow ADUs in single-family zones.

Key details: Code: Hialeah Zoning Code (Part III). State Law: FL §163.31771 (HB 1031, 2024). Building Code: FBC 8th Ed (HVHZ). Permit Agency: Hialeah Building Department. Flood Compliance: FBC §1612 + MDC 11C.

Constructing an ADU without permits triggers a Hialeah Code Enforcement Notice of Violation, daily fines accruing as a lien on the property, mandatory permit-after-the-fact at double fees, or removal. Building below BFE in a flood zone: order to elevate or floodproof at owner's cost.

ADU Owner Occupancy

Hialeah does not impose an owner-occupancy mandate on accessory dwelling units. Florida HB 1031 (2024), codified at FL §163.31771, encourages municipalities to allow ADUs without unduly restrictive conditions. Homestead Exemption (FL Constitution Art. VII §6) applies only to the owner's primary residence — renting both units forfeits the exemption.

Key details: City Requirement: None. State Policy: FL §163.31771 (HB 1031). Homestead Risk: Lost if owner moves out. HOA Authority: FL Ch. 720 (private rules). Source of Income: Protected (MDC §11A-26).

City-level: none for owner-occupancy. Homestead loss: Miami-Dade Property Appraiser backbills lost exemption with penalties and interest. HOA: private fines per declaration. Source-of-income discrimination: Miami-Dade Commission on Human Rights enforcement.

Hialeah is more permissive than most cities when it comes to adu owner occupancy. That said, there are still limits.
