Notice of Acceptance

This prefix tells you it's a Miami-Dade County product approval, required for all HVHZ installations.

HVHZ Certified
Year Code
2023 Approval Year

The two-digit year when this product was approved. Valid for 7 years, so this expires in 2030.

Expires: 2030
Application Number
Sequential ID: 1128

The 1,128th application submitted in 2023. This unique number identifies the specific product line.

Anatomy of an NOA Number

Every piece of the NOA tells a story about the product's wind load certification.

1

NOA Prefix

Identifies Miami-Dade Product Control approval. Only products with NOA can be installed in High Velocity Hurricane Zones where wind speeds exceed 180 mph.

NOA = HVHZ Approved
2

Year Code (XX)

Two-digit year of original approval. Calculate expiration by adding 7 years. Products must be re-tested and re-approved before expiration.

23 = 2023 + 7 = 2030
3

Application (XXXX)

Sequential application number for that year. This identifies the specific manufacturer and product line approved under this certificate.

1128 = 1,128th App
4

Revision (.XX)

Amendment number tracking changes to the original approval. Higher numbers may include additional sizes, improved ratings, or corrected specifications.

.05 = 5th Revision
5

Test Protocols

NOA products are tested per TAS 201 (impact), TAS 202 (uniform load), and TAS 203 (cyclic pressure). Wind load ratings are certified at 1.5x design pressure.

TAS 201/202/203
6

Validity Period

All NOAs are valid for exactly 7 years. During permit review, inspectors verify the NOA hasn't expired. Expired NOAs cannot be used for new installations.

How to Verify an NOA

Before specifying any product for wind load compliance, always verify its NOA status.

Find the NOA Number

Locate the NOA number on product labels, spec sheets, or manufacturer documentation. It's always in NOA XX-XXXX.XX format.

Frequently Asked Questions

Common questions about NOA numbers and wind load certifications.

What does NOA stand for in Florida building?
+
NOA stands for Notice of Acceptance. It's Miami-Dade County's product approval system certifying that building products meet High Velocity Hurricane Zone (HVHZ) requirements for wind loads up to 180+ mph. This is the gold standard for hurricane protection products.
How do I read an NOA number?
+
NOA numbers follow the format NOA XX-XXXX.XX where the first two digits indicate the year of approval, the next four digits are the sequential application number, and the final two digits represent revisions or amendments. For example, NOA 23-1128.05 means approved in 2023, application #1128, revision 5.
How long is an NOA valid?
+
Miami-Dade NOAs are valid for 7 years from the date of issuance. Products must be re-tested and re-approved before expiration to maintain certification for HVHZ installations. Always verify the expiration date on the Product Control website before specifying.
What's the difference between NOA and FL Product Approval?
+
NOA is specific to Miami-Dade County's HVHZ requirements with stricter testing protocols (TAS 201, 202, 203). FL Product Approval covers the rest of Florida. Products for HVHZ must have NOA; standard Florida zones can use either. NOA products generally have higher pressure ratings and include impact testing.
Where can I verify an NOA number?
+
Verify NOA numbers on Miami-Dade County's Product Control website at miamidade.gov. Enter the NOA number to see the full approval document, tested configurations, pressure ratings, and expiration date. This verification is essential before permit submission.
