T3 — Sub-Urban Transect Zone

The lowest-intensity residential transect zone commonly found in established single-family neighborhoods. T3 areas are characterized by detached houses on larger lots with significant landscaping and tree canopy. T3 includes sub-variants T3-L (limited) and T3-O (open) with slightly different lot and building standards.

Typical uses: Single-family dwelling, Accessory dwelling unit, Home occupation, Civic uses, Community garden

Max height: 35 ft (2.5 stories). FAR: 0.6:1 (T3-L); varies by lot width (T3-O). Min lot size: 5,000 sq ft (T3-L); 6,500 sq ft (T3-O). Setbacks: Front: 20 ft, Side: 5–7.5 ft, Rear: 15 ft. Lot coverage: 45–50%.

Developer notes: T3 parcels in neighborhoods like Little Havana and Coconut Grove are increasingly targeted for ADU additions and small-scale infill. The form-based code allows flexibility in building form that traditional zoning does not.

T4 — General Urban Transect Zone

A moderate-density zone providing a transition between suburban neighborhoods and more urban areas. T4 includes sub-variants T4-L (limited), T4-O (open), and T4-R (restricted). Permits a mix of housing types including townhouses, small apartment buildings, and live-work units.

Typical uses: Townhouses, Small apartment buildings, Live-work units, Duplexes, Civic uses, Limited ground-floor commercial

Max height: 45 ft (3 stories, T4-L); 55 ft (4 stories, T4-O). FAR: 1.5:1 (T4-L); 2.0:1 (T4-O). Min lot size: 5,000 sq ft. Setbacks: Front: 10 ft, Side: 0–5 ft, Rear: variable. Lot coverage: 60–70%.

Developer notes: T4 is the sweet spot for mid-density infill — townhomes and small apartment buildings. T4-O parcels in emerging neighborhoods like Little Havana offer strong development potential with moderate entitlement complexity. The form-based framework means design compliance matters more than use permits.

T5 — Urban Center Transect Zone

A higher-density urban zone intended for mixed-use buildings along major corridors and neighborhood centers. T5 includes sub-variants T5-L (limited), T5-O (open), and T5-R (restricted). Ground-floor commercial or liner uses are typically required along primary frontages.

Typical uses: Mixed-use buildings, Apartments, Offices, Retail, Restaurants, Hotels, Civic uses

Max height: 65 ft (5 stories, T5-L); 75 ft (6 stories, T5-O). FAR: 2.5:1 (T5-L); 3.0:1 (T5-O). Min lot size: 5,000 sq ft. Setbacks: Front: 0–10 ft (build-to line), Side: 0 ft, Rear: variable. Lot coverage: 80%.

Developer notes: T5 zones are where form-based code truly shines for developers. Mixed-use is permitted by default — no special use permits needed. T5 parcels along corridors like Calle Ocho (SW 8th Street), Coral Way, and Biscayne Boulevard are prime for mixed-use mid-rise development.

T6-8 — Urban Core — 8 Stories

The entry-level Urban Core transect zone permitting mid-rise development up to 8 stories. Found in transitional areas between T5 corridors and higher-density T6 sub-zones. Allows intensive mixed-use development with required ground-floor activation.

Typical uses: Mixed-use towers, Apartments, Condominiums, Hotels, Offices, Retail, Restaurants

Max height: 96 ft (8 stories). FAR: 4.0:1 (with bonuses up to 5.0:1). Min lot size: 10,000 sq ft. Setbacks: Front: 0–10 ft (build-to line), Side: 0 ft, Rear: 10 ft. Lot coverage: 80%.

Developer notes: T6-8 parcels are often the most efficient development sites in Miami — the 8-story limit keeps construction within concrete podium + wood-frame or full concrete mid-rise, avoiding the cost premium of true high-rise construction. Excellent for workforce housing bonus projects.

T6-12 — Urban Core — 12 Stories

Permits mid-rise to high-rise development up to 12 stories. Found in areas transitioning toward the densest urban core, including parts of Edgewater, the Miami River corridor, and edges of Brickell.

Typical uses: Mixed-use towers, Condominiums, Apartments, Hotels, Offices, Retail

Max height: 144 ft (12 stories). FAR: 6.0:1 (with bonuses up to 7.5:1). Min lot size: 15,000 sq ft. Setbacks: Front: 0–10 ft (build-to line), Side: 0 ft, Rear: 10 ft. Lot coverage: 80%.

Developer notes: T6-12 enters true high-rise territory requiring concrete or steel construction. The jump from T6-8 significantly increases construction cost per square foot. Sites need to be large enough (15,000+ sq ft) to support efficient tower floorplates. Popular in Edgewater and along the Miami River.

T6-24 — Urban Core — 24 Stories

High-rise zone permitting development up to 24 stories. Concentrated in Brickell, Downtown, and Edgewater where density and transit access support intensive development.

Typical uses: High-rise condominiums, Luxury apartments, Class A offices, Hotels, Mixed-use towers

Max height: 288 ft (24 stories). FAR: 9.0:1 (with bonuses up to 12.0:1). Min lot size: 20,000 sq ft. Setbacks: Front: build-to line, Side: 0 ft above podium, Rear: 10 ft. Lot coverage: 80%.

Developer notes: The workhorse high-rise zone in Miami. Most of the condo and apartment towers built in the 2020s cycle in Brickell and Edgewater fall in T6-24. Workforce housing bonuses can push FAR significantly higher. Site assemblage is critical — the 20,000 sq ft minimum lot size requires combining multiple parcels in many cases.

T6-36 / T6-48 — Urban Core — 36 to 48 Stories

High-rise zones in the densest parts of Brickell and Downtown. T6-36 permits up to 36 stories; T6-48 permits up to 48 stories. These zones represent the core of Miami's skyline and support the most intensive development in the city.

Typical uses: Supertall condominiums, Luxury residential towers, Major office towers, Full-service hotels, Large-scale mixed-use

Max height: 432 ft (T6-36); 576 ft (T6-48). FAR: 12.0:1 to 17.0:1 (with public benefit bonuses). Min lot size: 25,000+ sq ft. Setbacks: Build-to line at street, tower setbacks above podium vary. Lot coverage: 80% (podium), tower footprint limited above.

Developer notes: Reserved for the most capitalized developers and institutional projects. Construction costs for 36–48-story towers in Miami are among the highest in the Southeast. The public benefit program allows substantial FAR bonuses for workforce housing, public space, green building, and civic contributions. Brickell and Downtown sites in these zones command premium land prices.

T6-60 / T6-80 — Urban Core — 60 to 80 Stories

The most intensive transect zones in Miami, permitting supertall towers up to 60 and 80 stories. Applied to limited areas in the Downtown core and Brickell where the city envisions its tallest buildings.

Typical uses: Supertall mixed-use towers, Ultra-luxury condominiums, Trophy office towers, Five-star hotels

Max height: 720 ft (T6-60); 960 ft (T6-80). FAR: 18.0:1+ (with public benefit bonuses). Min lot size: 30,000+ sq ft. Setbacks: Build-to line at street, significant tower setbacks above podium.

Developer notes: Supertall territory — only a handful of sites in Miami carry this designation. Projects in these zones are $500M+ developments typically backed by sovereign wealth, major REITs, or international capital. The public benefit program is essential to achieve maximum entitlements. FAA height review is required for all projects approaching these limits due to proximity to Miami International Airport.

D1 — District Zone — Wynwood/Edgewater

Special district zoning applied to the Wynwood Arts District and parts of Edgewater. D1 establishes unique standards tailored to these neighborhoods' character, including provisions for galleries, studios, maker spaces, and creative uses alongside residential and commercial.

Typical uses: Art galleries, Studios, Maker spaces, Restaurants/bars, Retail, Apartments, Offices, Hotels

Max height: 60–150 ft (varies by sub-area). FAR: 3.0–8.0:1 (varies by sub-area). Min lot size: Varies by sub-area. Setbacks: Build-to line required; varies by frontage.

Developer notes: Wynwood's D1 zoning was custom-crafted to preserve the neighborhood's creative character while allowing development. The Wynwood Neighborhood Revitalization District (NRD) overlay adds specific design requirements around street activation, murals, and pedestrian experience. One of the most in-demand development neighborhoods in Miami.

D2 — District Zone — Civic/Health District

Applied to institutional campuses and the Health District area. Allows large-scale institutional and medical facilities with associated commercial and residential uses.

Typical uses: Hospitals, Medical offices, Research facilities, Educational institutions, Residential, Supporting retail

Max height: Varies by sub-area (up to 20+ stories in Health District). FAR: Varies by campus plan.

Developer notes: Health District parcels are increasingly attractive for medical office and life sciences development. Proximity to Jackson Memorial Hospital and the University of Miami Medical Campus creates a built-in tenant base. Mixed-use developments combining medical office with residential are gaining traction.

CI — Civic Institution Zone

Designated for civic, institutional, and public uses including government buildings, schools, religious institutions, and cultural facilities. Building standards are flexible to accommodate the variety of civic building types.

Typical uses: Government offices, Schools, Religious institutions, Cultural facilities, Parks, Community centers

Max height: Determined by adjacent transect zone context. Setbacks: Determined by adjacent transect zone context.

Developer notes: CI-zoned parcels occasionally come to market when institutions relocate or consolidate. These sites often have development potential if rezoned to an adjacent transect zone. The entitlement process for CI-to-transect conversions involves a comprehensive plan amendment and can take 12–18 months.

Wynwood Neighborhood Revitalization District (NRD-1)

A special area plan governing the Wynwood Arts District with tailored development standards that balance creative neighborhood character with new development. Establishes specific sub-areas with varying height and density allowances.

Affected areas: Wynwood Arts District — roughly bounded by I-95, NW 29th Street, N. Miami Avenue, and NW 20th Street

Key restrictions: Height limits vary by sub-area (generally 8–12 stories); Required ground-floor activation with retail, gallery, or restaurant uses; Design standards for street walls, facades, and pedestrian experience; Mural and public art provisions

Developer implication: Wynwood is one of the most active development markets in Miami. The NRD provides predictability but imposes specific design requirements that add to soft costs. Ground-floor retail/gallery requirements mean developers need a retail leasing strategy from day one. The neighborhood's brand cachet supports premium rents for both residential and commercial space.

Miami River Corridor (SAP)

Special area plan for development along the Miami River, establishing standards that balance waterfront activation, marine industrial preservation, and mixed-use development. The river is designated as a working waterway with protected marine uses.

Affected areas: Properties fronting the Miami River from Biscayne Bay west through the urban core

Key restrictions: River setback and public riverwalk requirements; Marine industrial use protections on designated parcels; Height transitions from river edge; Public access and activation requirements along the waterfront

Developer implication: The Miami River is an emerging development frontier. Waterfront parcels are extremely valuable but come with riverwalk dedication requirements and potential marine use restrictions. Developers should verify whether a specific parcel has marine industrial protections before acquisition. Mixed-use projects with river frontage command significant premiums.

Brickell Citycentre SAP

Special area provisions for the greater Brickell area establishing enhanced development standards for Miami's densest neighborhood. Addresses pedestrian connectivity, tower spacing, shadow impacts, and ground-floor activation.

Affected areas: Brickell — roughly from the Miami River south to SE 15th Road, between I-95 and Biscayne Bay

Key restrictions: Tower separation and floorplate requirements above podium; Required pedestrian connections and through-block passages; Enhanced ground-floor activation standards; Shadow and wind impact considerations for tall buildings

Developer implication: Brickell is Miami's premier high-rise market with T6-24 through T6-80 zoning. Land prices are among the highest in the Southeast. Tower separation requirements mean efficient site planning is critical — developers must balance floorplate efficiency against required setbacks. The public benefit program is the path to maximizing FAR.

Little Havana Neighborhood Conservation District (NCD)

Conservation overlay protecting the cultural character of Little Havana while allowing moderate intensification. Establishes context-sensitive design standards and use protections for this historically significant neighborhood.

Affected areas: Little Havana — centered on Calle Ocho (SW 8th Street) from approximately SW 4th Avenue to SW 27th Avenue

Key restrictions: Context-sensitive height transitions near historic areas; Design standards respecting neighborhood character; Protections for culturally significant uses; Enhanced review for demolition of contributing structures

Developer implication: Little Havana is one of Miami's fastest-emerging neighborhoods for development. The NCD adds design review requirements but does not prohibit development. T4 and T5 zoning along Calle Ocho allows mid-rise mixed-use. Developers should budget for additional design review time and be sensitive to the community's cultural identity in project planning.

Coconut Grove Neighborhood Conservation District (NCD)

Conservation overlay for Coconut Grove establishing design standards that protect the neighborhood's village character, tree canopy, and pedestrian-scale streetscape while allowing continued development.

Affected areas: Coconut Grove — the historic village center and surrounding residential neighborhoods

Key restrictions: Strict tree preservation and canopy requirements; Building height and mass limitations near the village core; Pedestrian-oriented design standards; Enhanced review for projects near historic structures

Developer implication: Coconut Grove's NCD makes it one of the more design-regulated areas in Miami. The tree preservation requirements can significantly affect site yield — a thorough arborist survey is essential before acquisition. Despite the added complexity, Coconut Grove's affluent demographics and limited supply support premium pricing for new development.

Miami 21 Form-Based Code Favors Mixed-Use by Default

Unlike traditional zoning where mixed-use requires special permits or overlay districts, Miami 21 allows mixed-use development by-right in T4 through T6 zones. This eliminates a major source of entitlement risk — developers do not need to rezone or obtain conditional use permits to build residential above retail. In T5 and T6 zones, ground-floor commercial is not just allowed but required, creating a built-in mixed-use framework that reduces regulatory uncertainty.

Workforce Housing Bonus Unlocks Significant Density

Miami's workforce housing bonus program allows developers to exceed base FAR and density limits by providing income-restricted units (typically at 60–140% AMI). In T6 zones, the bonus can increase FAR by 25–50%, representing millions of additional square feet of sellable or leasable area on large sites. For projects where additional density more than offsets the revenue reduction from affordable units, the workforce housing bonus substantially improves project economics.

Sea Level Rise and Climate Adaptation Are Reshaping Development

Miami has been a national leader in integrating climate resilience into its zoning code. New construction must meet base flood elevation plus freeboard requirements, stormwater management standards have been strengthened, and the city is increasingly incorporating sea level rise projections into planning decisions. Developers should factor in higher first-floor elevations (which affect ground-floor retail viability and podium design), enhanced drainage requirements, and potential future regulations. Sites at higher elevations — particularly the Brickell/Downtown ridge — carry a resilience premium.

Brickell and Edgewater Remain the Densest Development Corridors

Brickell and Edgewater carry T6-24 through T6-80 zoning, supporting the tallest and densest development in the Southeast. Brickell has evolved from a financial district into a 24/7 live-work-play neighborhood, while Edgewater is rapidly densifying with waterfront condo and apartment towers. Both neighborhoods benefit from Metromover/Metrorail access. Despite high land costs, the allowable density in these zones makes per-unit land basis competitive with lower-density markets.

Wynwood and Little Havana Offer Emerging Neighborhood Upside

Wynwood has transformed from a warehouse district into one of the most desirable mixed-use neighborhoods in Miami, with D1 zoning allowing 8–12-story development. Little Havana, with its T4 and T5 zoning along Calle Ocho, is the next frontier — land is significantly cheaper than Brickell or Edgewater, and the neighborhood's cultural cachet is attracting national attention. Both neighborhoods offer developers the opportunity to enter at lower basis while the market is still maturing.

FAA Height Restrictions Limit Buildable Height Near MIA

Miami International Airport (MIA) is located just 6 miles west of Downtown, and FAA obstruction surfaces extend over much of the urban core. Even parcels zoned for T6-60 or T6-80 may be limited to lower heights by FAA review. Developers pursuing tall buildings anywhere in the city should conduct an FAA Part 77 analysis early in due diligence — before acquiring land based on theoretical zoning height limits. Several proposed towers have been reduced in height due to FAA restrictions.

What is Miami 21 and how is it different from traditional zoning?

Miami 21 is a form-based code adopted in 2009 that replaced the city's traditional Euclidean zoning ordinance. Unlike use-based zoning, Miami 21 regulates building form, placement, and frontage type rather than primarily controlling land use. The code is organized around transect zones (T1 through T6) that increase in intensity from natural/rural to urban core. Mixed-use development is allowed by-right in most zones — you do not need special permits to combine residential and commercial uses.

What are transect zones and how do they work?

Transect zones are the organizing principle of Miami 21, ranging from T1 (Natural) to T6 (Urban Core). Each zone establishes building form standards — height, setbacks, lot coverage, frontage types — rather than use restrictions. T3 is low-density residential, T4 is moderate urban, T5 is urban center (mixed-use corridors), and T6 is urban core (high-rise). T6 has sub-variants by height: T6-8, T6-12, T6-24, T6-36, T6-48, T6-60, and T6-80 (stories).

Does Miami require parking for new developments?

Yes, Miami still requires off-street parking, though requirements are lower than many cities. Rates vary by transect zone and use — typically 1.0–1.5 spaces per residential unit and 3–4 spaces per 1,000 sq ft of commercial space. Parking reductions are available for sites near Metrorail and Metromover stations, and for projects participating in the workforce housing bonus program.

How does the workforce housing bonus program work?

The workforce housing bonus allows developers to exceed base FAR and density limits by providing income-restricted units (typically at 60–140% AMI). The bonus can increase FAR by 25–50% in T6 zones. Developers choose between providing on-site affordable units or making a fee-in-lieu payment to the city's affordable housing trust fund. The on-site option is generally more economically advantageous for large projects where the additional density exceeds the cost of below-market units.

What are the climate and sea level rise requirements for new construction in Miami?

Miami requires new construction to be built above the base flood elevation plus additional freeboard (typically 1–2 ft above FEMA BFE). The city has adopted enhanced stormwater management standards, and sea level rise projections are increasingly being incorporated into infrastructure and planning decisions. Developers should factor in elevated first-floor construction, potential impacts on ground-floor retail design, and enhanced drainage requirements.

How long does a typical zoning approval take in Miami?

For by-right development that complies with Miami 21 standards, no zoning approval is needed beyond building permit review — a major advantage of the form-based code. For projects requiring a Warrant (minor deviation) or Exception (major deviation), timelines vary: Warrants are typically reviewed at the administrative level in 4–8 weeks, while Exceptions require Planning, Zoning and Appeals Board review, taking 3–6 months. Comprehensive plan amendments or special area plan modifications can take 12–18 months.

What is the public benefit program and how does it increase development rights?

The public benefit program allows developers in T6 zones to exceed base FAR and height limits by providing community benefits such as workforce housing, public open space, green building certification, public parking, civic space, or infrastructure improvements. The specific bonus depends on the benefit type and the transect sub-zone. Workforce housing is the most commonly used benefit, as it provides the greatest FAR increase per dollar invested.

Are there FAA height restrictions in Miami?

Yes. Miami International Airport is located approximately 6 miles west of Downtown, and FAA obstruction surfaces extend over much of the urban core. Even parcels zoned for T6-60 or T6-80 may have actual buildable height limited by FAA Part 77 review. Any proposed structure exceeding 200 ft or within approach/departure surfaces requires FAA notification and review. Conduct an FAA analysis early in due diligence before acquiring sites based on zoning height limits alone.
