Pompano Beach Floors: the Permit Hinges on What’s Below You
Pompano Beach has a twist the others don’t: a flooring permit is only required when your condo sits above another unit or a public area. Ground-floor units, single-family homes, and commercial spaces are exempt. If you are above a neighbor, going from carpet to tile or LVT needs an acoustic report proving the assembly meets Florida Building Code §1207 at STC 50 and IIC 50. Try our IIC Calculator first.
What Pompano’s Sound Barrier Checklist Asks For
The City of Pompano Beach publishes a Flooring / Sound Barrier Checklist for condo work. The centerpiece is a Sound Transmission and Acoustic report showing your flooring and underlayment clear STC and IIC 50, and it has to match your real site conditions, down to a drop ceiling versus none and a 6-inch versus 8-inch slab.
The 5 Items on the Pompano Checklist (in 2026)
- Broward County Uniform Permit Application: Building box checked, from a licensed building contractor.
- Condo Association Approval Letter: the board signing off on the proposed work.
- Floor Plan: the unit drawing marking the scope of work.
- Sound Transmission / Acoustic Report: flooring plus underlayment clearing STC and IIC 50, matched to site conditions.
- Notice of Commencement: recorded with Broward County when the contract tops $2,500.
Only stacked condo units need this. You start the application in Click2Gov, then upload the plans and acoustic report through the city’s ePlan review. Building fees run about 2.75% of the job value with a $65 minimum. The Building Inspections Division is reachable at (954) 786-4669.
Pompano Beach inspects the work in two stages. A Sound Barrier In-Progress inspection confirms the underlayment and adhesive match your approved report before the finish goes down, and a building final closes the permit once that passes.
STC, IIC, and Why Site Conditions Matter
- STC (Sound Transmission Class): airborne noise — talking, a stereo, a TV through the floor.
- IIC (Impact Insulation Class): impact noise — footsteps, a dropped phone, a sliding chair.
Section 1207 of the Florida Building Code sets both ratings at 50 between stacked units. STC covers airborne sound, measured under ASTM E90, and IIC covers impact sound, measured under ASTM E492 with a tapping machine. Pompano ties the report to your actual flooring and underlayment, so our lab-tested assemblies ship formatted for a Pompano Beach submittal.
At IIC 50, a footstep upstairs lands as a dull thud instead of a sharp knock. A bare slab with tile usually sits in the high 20s, so the rated underlayment is doing the real work. Our IIC/STC ratings guide for condo flooring permits covers how different assemblies reach the number.
Why the Same Floor Scores Differently
| Same underlayment, different assembly | Typical IIC | vs Code 50 | What It Means |
|---|---|---|---|
| 6-inch slab, no ceiling below | ~46 | Below 50 | Fails — spec a higher-rated underlayment |
| 8-inch slab, no ceiling below | ~49 | Below 50 | Just short — add a rated acoustic mat |
| 6-inch slab, drop ceiling below | ~53 | Passes | Clears 50 with room to spare |
| 8-inch slab, drop ceiling below | ~56 | Passes | Comfortable pass for inspection |
Illustrative only — the same mat can pass or fail depending on the slab and ceiling below. Your submitted report must reflect your building’s actual assembly.
The slab below you and whether there is a drop ceiling can swing the IIC by ten points or more, enough to turn a passing assembly into a failing one. That is why Pompano wants the report matched to your actual building, not a generic lab setup.
What to Aim For in a Pompano Beach Condo
| Building Type | Wall STC | Floor IIC | What It Is / Where |
|---|---|---|---|
| 1970s–80s Cypress Bend / Palm-Aire | 52–55 | 55 | The big inland condo communities. Older slabs need an underlayment to clear the report. |
| Oceanfront Mid-Rise | 55 | 55–60 | The Hillsboro and Pompano Beach Boulevard strip. Boards commonly set IIC 55 once tile replaces carpet. |
| New Luxury Tower | 55–60 | 60 | Casamar and Salato near the rebuilt pier. Underlayment specs are written into the alteration rules at delivery. |
| Penthouse / Ultra-Luxury | 60+ | 65+ | Top-floor oceanfront units. A floating subfloor on a thick acoustic mat reads as effectively silent below. |
Pompano Beach holds roughly 144 condo buildings with published floor plans, from the inland communities of Cypress Bend and Palm-Aire to the oceanfront strip near the rebuilt Pompano Beach Pier. New luxury towers like Casamar and Salato are rising by the water while much of the older stock dates to the 1970s and 1980s. Those older slabs are where carpet-to-tile conversions miss the IIC 50 mark.
Because Pompano only permits stacked units, almost every project that needs this guide sits above a neighbor, in exactly the buildings most prone to footfall complaints. The middle two rows above are where most renovations should land. Mid-market to luxury (STC and IIC 52 to 60) is the right band for a Pompano condo that wants to clear the report and keep the board quiet.
Underlayments That Clear the Pompano Sound Barrier
- AcoustiStep: premium rubber mat. Right pick when the HOA requires IIC 55 or 60.
- Floor Blokker: standard acoustic underlayment roll. Clean STC and IIC pass for typical retrofits.
- Floor Blokker Lite: lighter, lower-cost option for budget retrofits that still need to clear code.
All three ship with published STC and IIC test reports you can match to your slab and ceiling conditions before they go into your Pompano submittal. The choice comes down to your board’s IIC threshold and how much margin you want above the §1207 minimum.
Clearing the Pompano Sound Barrier Inspection
A Pompano Beach flooring permit comes down to two things: an acoustic report that matches your actual slab and ceiling, and an installed underlayment that matches that report. File the Broward application, the condo letter, the floor plan, and the report through Click2Gov and ePlan, then pass the Sound Barrier In-Progress inspection before the final.
Every underlayment in the Commercial Acoustics catalog ships with the STC and IIC reports a Pompano reviewer needs, ready to match to your building’s conditions. Pick the product that meets your board’s threshold and the inspection is a formality.
FAQs: Pompano Beach Flooring Soundproofing Permits
Do I need a flooring permit if my Pompano condo is on the ground floor?
No. Pompano Beach only requires a flooring permit when your unit sits above another dwelling or a public area. Ground-floor condos, single-family homes, and commercial spaces are exempt. The rule is about who is below you, not the cost of the job.
What does the Pompano Beach sound barrier checklist require?
A Sound Transmission and Acoustic report showing your flooring and underlayment clear STC and IIC 50, plus the Broward permit application, a condo association letter, and a floor plan. The report has to match your real site conditions.
How much soundproofing does a Pompano Beach condo floor need?
Florida Building Code Section 1207 sets STC 50 and IIC 50 between units, tested per ASTM E90 and E492. A bare slab with tile falls well short, so a rated underlayment is what reaches the number on the report.
Why does Pompano ask about my ceiling and slab thickness?
Because they change the score. The same underlayment tests differently over a 6-inch versus 8-inch slab, or with a drop ceiling below versus none. Pompano wants the acoustic report to reflect your actual assembly, not a generic lab setup.
Does Pompano Beach inspect the floor?
Yes. A Sound Barrier In-Progress inspection verifies the underlayment and adhesive match your approved report before the finish covers them, and a building final closes the permit once that passes.
How do I file a Pompano Beach flooring permit?
Start the application in Click2Gov, then upload your plans and acoustic report through the city’s ePlan review. Reach the Building Inspections Division by phone at (954) 786-4669.
