# Miami-Dade Contractor Licensing and HVHZ Rules 2026: NOA & Permits

**Short answer: Under Code of Miami-Dade County Chapter 10 and the Florida Building Code High-Velocity Hurricane Zone (`HVHZ`), Miami-Dade contractor licensing and HVHZ rules are enforced by Miami-Dade RER and Florida DBPR. Contractors working in Miami-Dade and Broward counties must hold either a statewide Florida DBPR Certified license or a Miami-Dade Certificate of Competency, submit Miami-Dade Notice of Acceptance (`NOA`) product approval numbers for all exterior roofing, windows, doors, and shutters, record a Notice of Commencement on jobs over $5,000 ($15,000 for direct A/C changeouts), and pay 7% sales tax on real-property materials.**

Keeping your local credential numbers, permit receipts, and city-specific tax or fee lines organized on every estimate and invoice in Miami-Dade County and Broward County (High-Velocity Hurricane Zone) prevents municipal stop-work orders and payment delays.

State and provincial contractor guides rarely tell you what actually happens when your van pulls up to a curb in **Miami-Dade County and Broward County (High-Velocity Hurricane Zone)**. At the street level, municipal building departments, city tax collectors, transport authorities, and property management boards enforce a second layer of rules under [Miami-Dade County Department of Regulatory and Economic Resources (RER) & Florida DBPR](https://www.miamidade.gov/global/economy/building/contractor-licensing.page) (Code of Miami-Dade County Chapter 10 & Florida Building Code High-Velocity Hurricane Zone (HVHZ) / F.S. § 713.13). Below is the complete 2026 field guide to **miami dade contractor licensing and hvhz rules**, including a side-by-side compliance matrix, worked billing numbers, and how to structure your quotes and invoices so local inspectors and clients sign off without friction. For the broader regional rules, see [florida contractor license requirements](/keel/florida-contractor-license-requirements/) and [florida sales tax for contractors](/keel/florida-sales-tax-for-contractors/).

## Why do municipal rules in Miami-Dade County and Broward County differ from state or provincial rules?

Contractors who only check state or provincial licensing boards often get blindsided on their first job inside Miami-Dade County and Broward County (High-Velocity Hurricane Zone).

Miami-Dade and Broward counties form Florida’s High-Velocity Hurricane Zone (HVHZ), where contractors must hold either a Florida DBPR Certified license or a Miami-Dade Certificate of Competency, submit Miami-Dade Notice of Acceptance (NOA) product approval numbers for all exterior roofing, windows, doors, and shutters, record a Notice of Commencement on jobs over $5,000 ($15,000 for direct A/C changeouts), and pay 7% tax on real-property materials.

In Miami-Dade County, an exterior job cannot pass its first or final inspection without the printed Miami-Dade Notice of Acceptance (NOA) drawings taped to the permit board on site, and municipal building departments in City of Miami, Miami Beach, Coral Gables, Hialeah, and Doral will freeze inspections if the Notice of Commencement is not recorded.

## What are the key licensing, permit, and billing rules in Miami-Dade County and Broward County?

Use this reference table before quoting or pulling a permit in Miami-Dade County and Broward County (High-Velocity Hurricane Zone):

| Municipal Requirement / Rule | Trigger & Applicability in Miami-Dade County and Broward County | Fee, Tax & Invoice Impact |
|---|---|---|
| HVHZ Product Approval (Miami-Dade NOA) | All roofing, impact windows/doors, shutters, siding & fasteners | NOA approval packet must be on site for Miami-Dade RER inspection |
| Notice of Commencement (F.S. § 713.13) | Jobs >$5,000 (or >$15,000 for direct HVAC system replacement) | Recorded with Miami-Dade Clerk of Courts before first inspection |
| State DBPR Certified vs Local CTQB | Florida DBPR Certified (statewide) or Miami-Dade RER specialty | Local Certificate of Competency requires municipal registration & COI |
| Miami-Dade Sales Tax on Materials (7%) | 6% Florida state + 1% Miami-Dade discretionary surtax (first $5,000) | Contractor pays 7% at supply house on real property contracts; $0 billed on invoice |

## How do Miami-Dade HVHZ Notice of Acceptance (NOA) numbers and Notice of Commencement rules affect your billing?

Contracting in Miami-Dade County places you inside the **High-Velocity Hurricane Zone (HVHZ)** of the Florida Building Code, enforced by **[Miami-Dade RER](https://www.miamidade.gov/global/economy/building/contractor-licensing.page)** and the **[Florida Department of Business and Professional Regulation (DBPR)](https://www.myfloridalicense.com/)** alongside **[Florida Department of Revenue Rule 12A-1.051](https://floridarevenue.com/Forms_library/current/gt800007.pdf)**.

Protect every job in Miami, Miami Beach, Coral Gables, Doral, and Hialeah with three documentation habits:
1. **Record Miami-Dade NOA numbers directly on exterior estimates and invoices:** Whenever you install roofing systems, impact windows, exterior doors, shutters, or trusses in the HVHZ, listing the exact **Miami-Dade Notice of Acceptance (NOA)** number on your invoice satisfies municipal building inspectors and gives the homeowner permanent proof for OIR-B1-1802 wind-mitigation insurance credits.
2. **Track the $5,000 Notice of Commencement ($15,000 for HVAC) and 30-day permit clock:** Under Fla. Stat. § 713.13, a recorded Notice of Commencement is required before the first inspection on improvements over $5,000 ($15,000 for direct AC changeouts), and under Fla. Stat. § 489.126 taking a deposit over 10% requires applying for permits within 30 days.
3. **Follow the 7.0% Miami-Dade real property tax rule:** On lump-sum, cost-plus, or guaranteed-maximum real property contracts, you pay the 6% Florida state + 1% Miami-Dade discretionary surtax at the supply house and charge **$0 sales tax on the customer invoice**.

## What step-by-step audit checklist should you run before filing in 2026?

When you review your books at the end of the quarter or tax year for **miami dade contractor licensing and hvhz rules**, running a five-minute reconciliation between your issued client invoices, your supplier receipts, and your vehicle log prevents the most common audit adjustments:

1. **Verify Sequential Invoice Numbering and Dates:** Confirm that every completed job has a dated, sequentially numbered invoice showing the customer's legal name, the site address, and an itemized split between trade labor and direct materials.
2. **Match Material Receipts to High-Value Jobs:** Whenever a project involves significant supply-house purchases, equipment rentals, or municipal permit fees, keep the photographed vendor receipt filed under that specific job so you can prove your direct cost basis and input tax treatment in seconds.
3. **Cross-Check Statutory Registration Numbers:** Make sure your active tax identifier, trade licence number, and workers' compensation clearance reference are printed in your invoice template header so commercial accounts-payable teams never hold back a progress draw.
4. **Separate Pass-Through Taxes and Withholdings from Net Profit:** Whether your invoices involve sales tax, GST/HST, VAT, or statutory construction withholdings, treat tax collected in trust separately from your operating margin so quarterly remittances never catch your bank account short.

## How should you archive job records and receipts for multi-year retention?

Tax and licensing authorities require self-employed contractors to retain complete supporting records—including numbered invoices, paid supplier dockets, mileage logs, and permit sign-offs—for three to seven years depending on the jurisdiction. Exporting a clean PDF and CSV archive at the end of every quarter ensures your records remain accessible even if you change phones or trucks.

## Frequently asked questions

**Why should Miami-Dade roofers and window contractors print NOA numbers on customer invoices?**

In the High-Velocity Hurricane Zone (Miami-Dade and Broward counties), every exterior envelope product must hold a valid Miami-Dade Notice of Acceptance (NOA) or Florida HVHZ approval. Printing the NOA number on the invoice helps close out municipal permits and passes wind-mitigation insurance inspections. Keeping your sequential client invoices, dated supplier receipts, and compliance records filed under each job ensures you can verify these numbers immediately during any customer or tax review.

**Do I charge 7% sales tax on a lump-sum residential remodel or AC install in Miami-Dade?**

No. Under Florida Administrative Code Rule 12A-1.051, real property contractors performing lump-sum, cost-plus, or guaranteed-maximum contracts are the ultimate consumers of materials—meaning you pay the 7% tax at the supplier and bill $0 sales tax on the client's invoice. Keeping your sequential client invoices, dated supplier receipts, and compliance records filed under each job ensures you can verify these numbers immediately during any customer or tax review.

**What is the Florida 10% deposit and 30-day permit application law (Fla. Stat. § 489.126)?**

Under Florida Statute § 489.126, any contractor who receives an upfront deposit exceeding 10% of the contract price for residential work must apply for the required building permits within 30 days and commence work within 90 days of permit issuance, unless the contract specifies otherwise. Keeping your sequential client invoices, dated supplier receipts, and compliance records filed under each job ensures you can verify these numbers immediately during any customer or tax review.

**When is a recorded Notice of Commencement required on a Miami-Dade contracting job?**

Under Florida's Construction Lien Law (Fla. Stat. § 713.13), a Notice of Commencement must be recorded with the Miami-Dade Clerk of the Court and posted on the jobsite before the first inspection on any direct contract greater than $5,000 (or greater than $15,000 for direct HVAC repair/replacement).

**How do Florida DBPR state licenses and Miami-Dade local specialty certificates interact under HB 1383?**

Florida State Certified contractors (CGC, CBC, CRC, CCC, CAC, CFC, EC) can work county-wide by registering their state license and COI with local permit desks, while Florida HB 735 and HB 1383 preempted local non-structural specialty licensing to the state DBPR schedule. Keeping your sequential client invoices, dated supplier receipts, and compliance records filed under each job ensures you can verify these numbers immediately during any customer or tax review.
