How long does a Miami-Dade building permit take to issue?

A realistic timeline for general contractors and owners working in Miami-Dade County · Updated June 2026

For a contractor, the timeline is not trivia. The weeks a permit spends in review are your window to research the owner while the team may still be forming.

If you're a contractor watching for the right moment to bid, or an owner trying to schedule a project, knowing the realistic Miami-Dade timeline matters more than knowing the average. Miami-Dade is unique among major U.S. metros because permits aren't just slow or fast: they live in 30-plus different building departments, each with its own queue. The same scope of work takes a different amount of time in Doral than it does in Miami Beach.

How long does each Miami-Dade permit type take?

PermitPipeline tracks every new filing across Miami-Dade County and the major municipal jurisdictions. From the Miami-Dade Open Data ArcGIS feeds (Development Center and Code Compliance), the typical durations look like this:

These are observed medians from the past year of filings. The mean is much higher because of long-tail outliers — projects that stall in DERM appeals, environmental review, or HPB redesign cycles. If you're underwriting a schedule in Miami, plan from the median and budget contingency by jurisdiction. Beach projects need the most contingency.

What's actually happening between filing and issuance on a Miami-Dade permit?

The clock has four stages. Each has its own typical wait, and which jurisdiction you're in determines which stages exist at all.

1. Initial intake (1–5 business days). The filing is logged with the jurisdictional building department, fees calculated, and routed to plan review. Sub-permits to an open master permit can skip most of this and issue same day.
2. Plan review (2–10 weeks). A plan reviewer checks structural, electrical, plumbing, mechanical, and fire/life safety against the Florida Building Code with HVHZ amendments. They issue comments in writing. Most first submissions get at least one round of comments. The HVHZ requirement is well-understood by reviewers but means every product spec needs a current NOA (Notice of Acceptance) on file.
3. Special review when triggered (4 weeks to 6 months). Historic Preservation Board (Miami Beach, Coral Gables, parts of City of Miami), DERM environmental, coastal construction control line, traffic impact, or wetlands consultation. Each adds its own queue. The HPB is the most common slowdown for beach and Gables projects. See our companion article on the Miami-Dade county vs. municipal permit landscape.
4. Permit issuance (3–10 business days after final approval). Once all comments clear, fees are paid, and required signoffs are in, the permit issues. Sub-permits (electrical, plumbing, mechanical) often get pulled after the master permit issues, each with their own short queue.

Why does Miami-Dade plan review vary so much in duration?

Plan review is the second-biggest source of variance after jurisdiction choice. The first variable people miss: the same building, the same scope of work, will take three to ten times as long in Miami Beach as it will in unincorporated Miami-Dade.

What slows Miami-Dade plan review:

• HVHZ product NOA expired or missing. Every wind-load product (impact glazing, roof tile, garage door, soffit, fastener) needs a current NOA. If the spec sheet references an expired NOA, the reviewer will reject and ask for a replacement product. This is the single most common comment.
• DERM environmental review. Anything on or near a wetland, on a contaminated site, or within the Biscayne Bay watershed gets DERM review. Adds 4–16 weeks. Common in southern Miami-Dade, Cutler Bay, and parts of Coral Gables.
• Historic Preservation Board hearing. Miami Beach, Coral Gables, and designated districts in City of Miami all have HPB hearings monthly. Miss one month, wait the next. Design changes after a hearing trigger another hearing.
• Coastal Construction Control Line (CCCL) review. Florida DEP reviews anything seaward of the CCCL. Adds 2–4 months. Common on the beach, in Surfside, Bal Harbour, and Sunny Isles.
• Flood elevation certificate missing or incorrect. Half of Miami-Dade is in FEMA AE or VE flood zones. Wrong base flood elevation in the drawings will stop the permit cold.
• Miami 21 zoning code interpretation needed. The City of Miami's form-based code requires zoning verification on any expansion or use change. Adds 2–6 weeks.

What's already happening on a project before the Miami-Dade permit issues?

This is the part most contractors miss: by the time the filing is in the public record, the owner has been planning for months. The architect is engaged. The structural engineer has run wind calcs. The general contractor may already be in conversations. The MEP subs are often pre-selected, especially in Miami where established relationships dominate.

The implication: the public filing is your one of the last public signals before the team is likely more fixed. Wait until permit issuance and the bid list has usually closed. Reach out at filing and you may be earlier than after issuance, especially on jobs where the owner doesn't have a long-standing Miami GC relationship. In Miami specifically, out-of-state owners and first-time developers are the highest-yield outreach targets because they don't have the local network yet.

How can Miami-Dade timing data help contractors bid smarter?

Once you know the typical wait by job type and jurisdiction, you can be strategic about which filings to chase first. Three quick rules:

• Major alteration filings in incorporated cities are your sweet spot. Long enough wait (3–6 months) that you have time to research the owner. Real enough that the project is committed and likely to break ground.
• New construction filings need patience. A new residential filing in Miami-Dade might be 6–12 months from groundbreaking. Build the relationship now, but don't expect a quick close. Earlier is better — see why.
• Skip pure sub-permits. The wait is short and the work is usually already underway. The exception: sub-permits to a fresh master permit are an early signal that the master is real and active.

What practical Miami-Dade permit timeline can a contractor use?

Here's how a realistic Miami-Dade alteration job in an incorporated city actually unfolds, with the dates you can research the owner at each step:

1. Day 0: Owner files job application. Filing appears in the Miami-Dade or municipal feed within 1–2 business days.
2. Days 0–30: Plan review queue. Owner is finalizing scope, often still picking GC.
3. Days 30–75: First round of plan review comments. Architect or engineer responds. This is the warmest window for outreach.
4. Days 75–120: Comment response and re-review. Special review (HPB, DERM) often runs in parallel here. GC is often being chosen around now, sometimes already selected.
5. Day 120–150: Permit issued. Work can begin. Bid list often closed or narrowing.

If you reach out in the days 30–75 window with a credible specific message, you may face less competition than after issuance. By day 120, you're competing in a more crowded field.

Why are most Miami contractors too late on the best work?

Most GCs check building department records after permits issue. That's the data that's easy to find and easy to filter. By then the bid list is set. The contractors who consistently win mid-market Miami-Dade work are the ones who've built a habit around the filing-to-issuance window. They're not waiting for the project to be advertised. They're treating the filing itself as the lead.

That's the workflow PermitPipeline is built around. Miami-Dade filings are scored, deduped, and emailed out the morning after they hit the public record, so your first chance to research the owner doesn't disappear into a 100-row CSV. See what today's Miami-Dade filings look like in our feed.
