Soundproofing Guides For
Flooring Permits
A city-by-city soundproofing guide for Florida condo and multi-family flooring renovations. Replacing carpet with tile, wood, or LVT above a neighbor almost always requires a permit plus proof your floor assembly meets STC and IIC 50 under Florida Building Code §1207. Pick your city below for the local permit checklist, the HOA documentation, and the underlayments that pass plan review.
Choose Your Florida City
Each guide covers that city’s permit portal, the HOA documentation its boards require, the STC/IIC 50 acoustic proof the building department wants, and the underlayments that pass plan review.
Every Florida City Asks for Three Things
The portal names change city to city, but the package is the same everywhere. Florida Building Code §1207 sets STC 50 and IIC 50 between dwelling units, and every building department wants proof before the permit is issued.
1. Acoustic Documentation
Manufacturer literature or a lab test report showing your exact floor assembly — slab, underlayment, and finish — rated STC 50 and IIC 50 or higher, tested per ASTM E90 and ASTM E492.
2. HOA Approval
The association signs off before the city will. Some boards want a simple approval letter. Others require a notarized affidavit, slab-thickness confirmation, or an IIC threshold above code, often 55 or 60.
3. City Permit Filing
Each city runs its own portal — eTRAKiT, iBuild, SmartGov, Accela, EPL, and the rest. The package uploads once, and most flooring permits clear plan review in a single round when it’s complete.
How the 13 Cities Compare
Same code, different paperwork. The affidavit column is the one that surprises owners — three cities require a notarized acoustic affidavit, and Miami Beach adds a dedicated soundproofing inspection on top.
| City | Permit Portal | Notarized Affidavit | What Makes It Different |
|---|---|---|---|
| Aventura | eTRAKiT | No | Flooring checklist + HOA letter must state slab thickness, perimeter isolation on tile |
| Boca Raton | eHub | Yes | 8-document submittal, the heaviest paperwork load on this list |
| Clearwater | ePermit | No | Finish-work exemption can apply, but HOAs still require rated underlayment |
| Delray Beach | City portal | No | Lightest city process in South Florida, boards carry the requirements |

| Pompano Beach | City portal | No | Acoustic report must match site conditions, ground-floor exemption in writing |
| St. Petersburg | City portal | No | Finish-work exemption similar to Clearwater, HOA rules still apply |
| Sunny Isles Beach | SmartGov | Yes | Owner’s Affidavit, fully digital since 2024, luxury boards spec IIC 60 |
| Tampa | Accela | No | Condo flooring files as a commercial permit even in residential towers |
| West Palm Beach | EPL | No | Standard interior-alteration pathway, underlayment literature carries the package |
Table 1: Florida flooring permit requirements by city. Every city above enforces FBC §1207 (STC 50 / IIC 50 between dwelling units, ASTM E90 / E492). Ground-floor units with no neighbor below are exempt from the soundproofing requirement everywhere.
Why STC and IIC 50 Decide Your Permit
STC measures airborne noise through the floor, a TV or conversation. IIC measures impact noise, footsteps and dropped items. A bare concrete slab with tile sits in the high 20s for IIC, which is why the rated underlayment is the heart of every permit package.
Our IIC Calculator estimates your assembly’s rating before you file. AcoustiStep, Floor Blokker, and Floor Blokker Lite all ship with the published STC and IIC test reports plan reviewers ask for.
FAQs: Florida Flooring Permits
Do I need a permit to change the flooring in my Florida condo?
In most cities, yes. Replacing carpet with tile, wood, or LVT in a unit above another dwelling triggers a permit because of the IIC 50 impact-noise requirement in Florida Building Code §1207. A few cities exempt finish-only work, but the HOA usually requires the documentation either way.
What is the difference between the city requirement and the HOA requirement?
The city enforces FBC §1207, which is STC 50 and IIC 50. The HOA can require more, an IIC 55 or 60 threshold, a notarized affidavit, board pre-approval, or a specific tested assembly. The city will not issue the permit until the association has signed off.
Will any underlayment pass IIC 50?
No. Felt and basic foam underlayments often land in the IIC 40s on a standard slab with tile on top. The assemblies that clear IIC 50 use engineered acoustic mats, and the rating belongs to the full assembly, not the product alone.
Do ground-floor units need soundproofing?
No. The §1207 requirement applies between dwelling units, so a ground-floor unit with no neighbor below is exempt in every city on this page. The flooring permit itself may still be required for the work.
What if my city is not listed here?
We work statewide. The FBC §1207 numbers apply everywhere in Florida, so we can build a compliant assembly, the acoustic report, and the HOA documentation for any jurisdiction, we simply have not published a local checklist page for every city yet.
