New Home Construction in Miami: Costs, Codes and Timelines

New home construction in Miami runs anywhere from $160 to more than $1,000 per square foot, depending on how you build and where. Miami-Dade County sits inside the most demanding wind zone in the continental United States, which shapes every cost and timeline figure below. Here is what the data shows for 2026.

What Does New Home Construction in Miami Cost?

Standard entry-level construction in Miami-Dade runs $160 to $180 per square foot. Mid-range custom builds run $150 to $300+ per square foot across Florida, with South Florida and coastal markets pushing toward the higher end.

Fully custom residences in South Florida's coastal markets typically land at $500 to $1,000 per square foot. A 2,000-square-foot home in those markets can reach $800,000 to more than $1 million in hard construction costs alone.

Those figures cover hard construction costs only. Soft costs come on top: general contractor fee of 10% to 20% of the construction budget, architecture and engineering of 5% to 9% of construction cost for custom Miami projects, and permit fee of 0.5% of projected construction cost in Miami-Dade.

Construction costs in South Florida rose 6% to 9% annually from 2022 through 2025, driven by labor shortages and strong regional demand. As of 2026, that pace has slowed to an estimated 3% to 5% annual growth, but costs remain well above their 2019 baseline.

Is New Home Construction in Miami Growing?

Miami-Dade issued 1,522 new residential building permits through Q3 2025, up 35% year over year. Much of that growth comes from a teardown-and-rebuild trend across established Southwest Miami-Dade neighborhoods. New construction in Miami-Dade has sold at 30% to 66% above the blended market price, depending on neighborhood, based on Compass MLS data for the six-month period ending March 2026.

A new build also delivers full compliance with current HVHZ wind and impact codes, so the envelope does not need retrofitting after purchase. New builds qualify for lower insurance premiums than older homes, and there is no deferred maintenance to inherit.

What Building Codes Apply to New Home Construction in Miami?

Miami-Dade enforces the 8th Edition (2023) Florida Building Code, effective December 31, 2023, along with the 2023 National Electrical Code. On top of the statewide code, Miami-Dade and Broward County carry the most stringent wind-borne debris and impact requirements in the country. Both counties fall entirely within the High Velocity Hurricane Zone (HVHZ).

The HVHZ is a designation under the Florida Building Code that applies to Miami-Dade County in its entirety. Design wind speeds in Miami-Dade run 170 to 200+ mph under ASCE 7-22 Risk Category II standards, the highest wind design requirement in the continental United States.

What Is the HVHZ and Why Does It Matter?

Every exterior envelope product on a new home must meet this standard. All glazed openings, including windows, entry doors, sliding glass doors and skylights, must carry a Miami-Dade Notice of Acceptance (NOA) or pass TAS 201/202/203 large-missile impact testing. Roofing systems must also hold Miami-Dade NOA approval, and structural calculations are mandatory for all HVHZ projects.

A window or door that carries a standard Florida product approval but lacks Miami-Dade NOA status cannot be legally installed in Miami-Dade. Contractors unfamiliar with NOA requirements will find out at inspection, not before, which costs time and money to correct.

Flood Zone Requirements Add Another Layer

Most Miami new construction properties fall within FEMA AE or VE flood zones. The lowest finished floor must be at or above the Base Flood Elevation (BFE). Local ordinance and flood insurance requirements typically add 1 to 2 feet of freeboard above BFE.

For coastal and lakefront sites, pier or elevated foundation systems are common. Getting the floor elevation certification right from the start protects both the certificate of occupancy and long-term insurance costs.

How the Miami Permit Process Works and How Long It Takes

Permitting is the single biggest schedule variable in new home construction in Miami. In unincorporated Miami-Dade, the full permit cycle for new construction typically runs 4 to 7 months. In Coral Gables or Miami Beach, where designs require board review, it can stretch to 9 to 12 months.

Initial plan review takes 1 to 10 business days, but that is only the first step in a multi-stage process.

Which Building Department Issues Your Permit?

Miami-Dade County's building department only issues permits for unincorporated areas, with folio numbers starting with 30. Miami-Dade contains 34 incorporated municipalities, including the City of Miami, Coral Gables, Miami Beach and Hialeah. Each runs its own building department with its own submission portal, fee schedule and review timeline.

Confirming jurisdiction before preparing permit documents avoids submitting to the wrong department entirely.

What Does a Permit Cost and What Does the Submission Require?

The residential building permit fee in Miami-Dade is 0.5% of projected construction cost. On a $600,000 hard-cost project, that is $3,000 in permit fees before any city-specific fees your jurisdiction may assess.

Construction documents must be prepared, signed and sealed by Florida-licensed design professionals. Miami-Dade no longer accepts scanned hard copies; submissions must use digital Adobe-compliant seals. Structural calculations are mandatory for all HVHZ projects.

Step-by-Step Process for Building a New Home in Miami

From raw land to certificate of occupancy, the timeline moves through nine distinct phases. Knowing what happens in each phase helps you anticipate delays and manage costs.

Phase 1: Land Acquisition and Due Diligence

Before any design work begins, the site needs a geotechnical soil investigation. Florida's sandy soil and high water table create foundation conditions that differ from inland U.S. markets. The soil report informs foundation type, depth and reinforcement, which directly affects the budget.

Zoning verification and any variance applications happen at this phase as well.

Phase 2: Design and Pre-Construction

Architecture and engineering fees for a custom Miami project typically run 5% to 9% of construction cost. The design team produces construction documents that satisfy HVHZ structural requirements and selects NOA-approved products for all glazed openings and the roofing system.

Errors or omissions at this phase cause rejection during plan review and restart the review clock.

Phase 3: Permitting

Budget 4 to 12 months for this phase, depending on location and complexity. This is not idle time. It is when product selections are finalized, subcontractors are engaged and materials are ordered.

Starting that coordination during permitting rather than after it compresses the overall schedule.

Phase 4: Site Preparation

Site clearing, grading and excavation typically take 2 to 6 weeks. Inspections are required at the end of this phase before foundation work can proceed.

Phase 5: Foundation

Foundation type is determined by soil conditions and flood zone requirements. A concrete slab runs $6 to $14 per square foot, or $12,000 to $40,000 total; pier and beam systems run $14,000 to $28,000. Coastal and lakefront properties requiring elevated construction will sit at the upper end of these ranges or above.

Phase 6: Framing and Shell

Shell framing typically takes 4 to 8 weeks. In Miami-Dade, the structural frame must accommodate the connection details required by HVHZ wind-load calculations.

This is also when the NOA-approved window and door rough openings are set. Changing opening sizes after framing is an expensive correction.

Phases 7 Through 9: Systems, Finishes and Certificate of Occupancy

Rough plumbing, electrical and HVAC follow framing, each requiring its own inspections. Insulation, drywall and interior fixtures come next, then finishes, then final inspections. Total construction time from groundbreaking to certificate of occupancy runs 12 to 22 months for most new single-family homes in South Florida.

Add the permitting window and the land and design phase, and a realistic timeline from site acquisition to move-in is 20 to 30+ months for most builds.

How to Choose a General Contractor for New Home Construction in Miami

The right general contractor for a Miami new build is not simply a builder with a Florida license. They need demonstrated HVHZ experience, fluency with Miami-Dade permit submission requirements and established relationships with NOA-approved product suppliers and licensed subcontractors.

Ask any prospective contractor:

Is your Florida CGC license current, and can you provide the license number?
Have you pulled permits for new single-family construction in Miami-Dade or Broward County within the last two years?
Do you manage the permit process in-house, or do you rely on an expediter?
Which structural engineer and architect do you work with, and are they familiar with HVHZ calculations?
Can you show examples of completed projects that received certificates of occupancy in this market?

Frequently asked questions

What is the typical cost of new construction in Miami?

Standard entry-level construction runs $160 to $180 per square foot. Mid-range custom builds run $150 to $300+ per square foot across Florida, higher in coastal South Florida. Luxury coastal custom builds reach $500 to $1,000+ per square foot, with a 2,000 sq ft coastal home potentially exceeding $1 million in hard construction costs. Add GC fees of 10% to 20% and architecture and engineering fees of 5% to 9% on top of hard construction costs.

How long does it take to build a new home in Miami?

Construction from groundbreaking to certificate of occupancy takes 12 to 22 months. Add permitting, which runs 4 to 7 months in unincorporated Miami-Dade and 9 to 12 months in some incorporated cities, and the full project timeline from site acquisition is typically 20 to 30+ months.

What building code applies to new home construction in Miami?

Florida's 8th Edition (2023) Florida Building Code, effective December 31, 2023, governs new construction in Miami. Miami-Dade is also subject to High Velocity Hurricane Zone requirements, the most stringent wind and impact standards in the continental U.S.

Do I need impact windows and doors in new Miami construction?

Yes. All glazed openings in Miami-Dade must meet Miami-Dade Product Approval (NOA) standards for the HVHZ. Standard windows that meet Florida Building Code elsewhere in the state do not qualify.

What permits are required to build a new home in Miami-Dade?

A residential building permit from the correct jurisdiction. If your property is in unincorporated Miami-Dade, you apply to Miami-Dade County. Properties in the 34 incorporated municipalities apply to that city's building department. Documents must be prepared and sealed by Florida-licensed design professionals, and structural calculations are mandatory for all HVHZ projects.

Is new construction in Miami more expensive than buying an existing home?

New construction commands a significant premium at sale: 30% to 66% above blended market prices in selected Miami-Dade neighborhoods, based on six-month Compass MLS data ending March 2026. Building from scratch also costs more upfront and takes longer. The tradeoff is a home built to current hurricane code, with no deferred maintenance and lower insurance premiums than older stock.

What is the HVHZ and how does it affect my new home build?

The High Velocity Hurricane Zone covers all of Miami-Dade County. Design wind speeds run 170 to 200+ mph under ASCE 7-22. Every exterior product, including windows, doors and roofing, must carry a Miami-Dade NOA or pass TAS testing. This adds cost compared to construction elsewhere in Florida, but it is a non-negotiable code requirement.
