Miami-Dade Residential Building Permits in 2026: How to Read the New-Construction Pipeline

Last updated: July 2026

Miami-Dade County authorized 16,535 new privately owned housing units in 2025, up from 10,608 in 2024, and 13,292 of those units sat in buildings of five units or more [1]. That is the county's highest annual total since 2006, and it was almost entirely a multifamily event. The first half of 2026 moved the other way. Through June, Miami-Dade authorized 4,694 units versus 7,707 in the same six months of 2025, with five-plus-unit permits falling from 6,219 to 3,273 while single-family held roughly flat at 1,155 [2]. For anyone underwriting a Miami purchase today, the practical reading is this: a large block of rental and condo supply was authorized in 2025 and will land in 2027 and 2028, because multifamily buildings averaged 19.6 months from permit to completion nationally in 2024, and 22.1 months for buildings of 20 units or more [3]. Meanwhile new authorizations are cooling, which points to a thinner delivery schedule at the back end of the decade. Miami-Dade residential building permits are a forward indicator with a roughly two-year fuse, not a description of today's market.

What a building permit does and does not tell you

The U.S. Census Bureau's Building Permits Survey counts housing units authorized by permit-issuing places. It measures intent, not construction. A permit is not a start, a start is not a completion, and some authorized units never get built. The survey also reports a declared construction valuation, which is a cost estimate filed with the jurisdiction, not a sale price and not an appraisal.

That distinction matters when you underwrite. Read a permit headline as current supply and you will be about two years early. Ignore permits entirely and you will be surprised by deliveries that were visible in the data long before the crane went up.

The 2025 surge was a multifamily story

Miami-Dade's 2025 total of 16,535 authorized units breaks down as 2,666 units in single-family structures, 318 in two-unit buildings, 259 in three and four-unit buildings, and 13,292 in buildings of five units or more [1]. Roughly four of every five authorized units were in mid-rise or high-rise format.

That mix is structural rather than a one-year quirk. Over the past decade, single-family authorizations in Miami-Dade have moved in a narrow band of roughly 1,450 to 2,900 units a year, while five-plus-unit authorizations have swung from about 5,500 to 13,300 [5]. The county is largely built out inside the Urban Development Boundary, so detached supply is constrained by land rather than by demand. Multifamily is where the volatility lives, and it responds to capital markets, entitlement policy, and construction financing rather than to buyer sentiment in any given quarter.

If you are looking at detached inventory in the established single-family submarkets, the permit data says very little new competing product is coming. If you are looking at a condo or a rental underwrite in Brickell, the permit data is a primary forward input.

The first half of 2026 cooled

Through June 2026, Miami-Dade authorized 4,694 units against 7,707 in the same six months of 2025 [2]. Almost all of the decline is multifamily: 3,273 units in five-plus-unit buildings this year versus 6,219 last year. Single-family authorizations were close to unchanged at 1,155 against 1,171.

Two readings are consistent with that pattern. One, 2025 pulled forward a batch of filings ahead of fee and code changes, and 2026 is the payback. Two, higher construction financing costs and softer condo pricing have made new multifamily harder to capitalize. Both can be true at once. The underwriting consequence is the same either way: the 2025 cohort still has to be absorbed, and the pipeline behind it is thinner.

The lag between permit and delivery

Nationally, buildings with two or more units averaged 19.6 months from permit authorization to completion in 2024, based on the Census Bureau's Survey of Construction. Larger buildings take longer: 15.3 months for two to four-unit buildings, 19.1 months for five to nine units, 19.2 months for 10 to 19 units, and 22.1 months for buildings of 20 or more units [3]. The South region multifamily average was 18.5 months.

Miami's tower product sits at the long end of that distribution, and those averages exclude the time between entitlement and permit issuance. A workable planning assumption for a large Miami-Dade high-rise is two years or more from permit to certificate of occupancy, with vertical concrete, storm season, and utility connections as the usual sources of slippage.

Applied to the data: most of the 13,292 multifamily units authorized in Miami-Dade during 2025 are 2027 and 2028 deliveries. The lighter 2026 authorizations imply lighter 2028 and 2029 deliveries.

What this means when you underwrite a purchase today

Condo buyers

Miami-Dade carried a 12.3-month supply of existing condominiums as of June 2026, against 4.9 months for single-family homes, with 15,930 total active listings countywide, down 14.9% year over year [4]. Layering two years of new multifamily deliveries onto a condo segment that is already long on inventory argues for conservative exit pricing and for real scrutiny of what specifically competes with your unit. Not all 13,292 authorized units compete with a 1970s waterfront building or with a detached house in Coconut Grove.

Rental holds

If you are modeling a rental, the deliveries that hit your submarket in 2027 and 2028 are the ones that cap rent growth. Underwrite concessions in the delivery years rather than a straight-line trend, and check the permit file for the specific census-adjacent area you are buying into rather than the county aggregate.

Single-family buyers

The permit data offers little relief here. Detached authorizations have not expanded in a way that changes the supply picture, and a 4.9-month supply is a tighter condition than the countywide headline suggests [4].

Sellers

The relevant question is not the county total but the delivery schedule within a mile or two of the address, in your unit type and price band. That is what shows up in days on market.

How to read the data yourself

Start with the Census Building Permits Survey county files. They are plain text, updated monthly, and run back decades.
Separate the one-unit line from the five-plus-unit line every time. Blending them hides the signal.
Compare year-to-date against the same period a year earlier, not against the prior month. Permit data is lumpy, since a single 400-unit filing can dominate a month.
Cross-check against Miami-Dade County's own permit records for parcel-level detail, since the county portal shows individual applications and their status.
Convert authorizations into deliveries by adding roughly two years for large multifamily, then test your exit assumptions against that year rather than this one.

If you want that translated into a specific building or block before you write an offer, that is what a buyer consultation is for.

Frequently asked questions

How many residential building permits did Miami-Dade issue in 2025?

Miami-Dade authorized 16,535 new privately owned housing units in 2025, including 2,666 in single-family structures and 13,292 in buildings of five units or more [1]. That was up from 10,608 units in 2024 and the highest annual total for the county since 2006.

Are Miami-Dade permits up or down in 2026?

Down. Through June 2026 the county authorized 4,694 units, compared with 7,707 in the first six months of 2025 [2]. The decline is concentrated in five-plus-unit buildings, while single-family authorizations were close to flat.

How long does it take a permitted unit to actually deliver?

Nationally, multifamily buildings averaged 19.6 months from permit to completion in 2024, and buildings of 20 or more units averaged 22.1 months [3]. Large Miami high-rises generally sit at or beyond the long end of that range, and entitlement time comes before the permit clock starts.

Does a permit surge mean prices will fall?

Not by itself. Permits describe future supply in a specific product type. What matters is whether those units compete with the asset you own or are buying, and how demand in that submarket evolves over the same window. A wave of studio and one-bedroom rentals affects a downtown investor condo differently than it affects a detached listing.

Where can I check permits for a specific address?

Miami-Dade County publishes permit records through its permitting portal, which lets you search by address or folio and review application status. For county-level trend work, the Census Building Permits Survey county files and the matching FRED series are the cleaner starting point.
