If you serve on a condo or cooperative board in South Florida, you’ve likely heard the phrase Senate Bill 4D more than once over the past few years. Signed into law in May 2022 following the Champlain Towers South collapse in Surfside, the legislation fundamentally changed what Florida condo associations are required to inspect, document, and fund.
Most of the public conversation has focused on roofs, walls, and foundations. But there’s a critical component of SB 4D that many boards are only now confronting: plumbing is explicitly included in the Structural Integrity Reserve Study — and the clock on compliance is not paused.
Here is what every condo and HOA board in South Florida needs to know.
What SB 4D Actually Requires
The law introduced two binding obligations for condominium and cooperative associations managing buildings three stories or higher:
Milestone Inspections
Buildings within three miles of the coast must undergo a structural inspection by a licensed engineer or architect when the building reaches 25 years of age, and every 10 years after that. Inland buildings have until age 30. These are not optional reviews — they are enforceable compliance events. Failure to complete them can result in fines of up to $5,000 per violation from the Department of Business and Professional Regulation, occupancy restrictions, and personal liability for board members.
Structural Integrity Reserve Studies (SIRS)
Associations must also fund reserves for the ongoing maintenance and replacement of key building systems. The SIRS must be completed every 10 years by a licensed engineer or architect and must include an assessment of remaining useful life and estimated replacement cost for each covered component.
The list of covered components includes the roof, load-bearing walls, floor, foundation, fire protection systems — and plumbing.
As of December 31, 2024, associations can no longer waive or partially fund reserves for structural components. Full reserve funding is now mandatory, and non-compliance exposes board members to personal legal liability.
The Plumbing Problem Most Boards Don’t See Coming
The plumbing systems subject to SB 4D review include the vertical drainage stacks — the pipes running behind the walls of your building that carry wastewater from every unit down to the main sewer connection. In most South Florida condominiums built before the 1990s, those pipes are cast iron.
Cast iron is often cited with a 50-year lifespan. In coastal South Florida, that number is closer to 25 to 30 years. Salt air, humidity, and the corrosive nature of wastewater accelerate deterioration significantly. Many buildings in Palm Beach, Broward, and Miami-Dade counties already have drainage systems that are at or past end-of-life — and some have no documentation to demonstrate otherwise.
When your milestone inspection comes, your engineer will need to assess and report on those pipes. If the condition is unknown or the documentation is absent, that becomes a liability on your reserve study and a flag in your inspection report.
The Gapping Problem: When “Lined” Doesn’t Mean Compliant
There’s another issue that’s surfacing in buildings that already invested in pipe lining. Some associations paid for a method known as “Gapping,” “Stop and Start,” or “Hybrid” lining — where liner material is installed in segments, with gaps or voids left between sections.
This approach does not meet the Florida Building Code. Under ASTM F1216 and ASTM F1743 — the two CIPP installation standards recognized by the state — lining must be continuous over the full length of the pipe, with no voids. A gapping installation also voids the manufacturer warranty.
Boards that chose that method believing it was a compliant, long-term solution may now face remediation costs ahead of their expected schedule. And when a milestone inspector reviews those pipes, a gapping installation is likely to be flagged.
If your building’s pipes were lined by another contractor, it’s worth having an independent camera inspection to verify whether the installation was code-compliant before your milestone inspection puts you in a reactive position.
What a Compliant Installation Looks Like
Code-compliant CIPP lining, installed correctly, provides:
- A continuous, seamless liner installed over the full pipe length — no gaps, no voids
- Side connection dimples at every lateral branch, reopened by remote-controlled cutting device after curing
- A post-installation inspection by the authority having jurisdiction, confirming ASTM F1216 or F1743 compliance
- A 50-year useful life rating that your structural engineer can document in your SIRS reserve schedule
That last point matters directly for your reserve study. A properly documented, code-compliant lining installation gives your engineer a clear remaining useful life figure to work with — and can significantly reduce the reserve funding obligation compared to a system approaching end of life with no rehabilitation on record.
How Pipelining Technologies Supports SB 4D Compliance
Pipelining Technologies, Inc. has served South Florida’s commercial and condo sector since 2004. We work directly with engineering firms, property management companies, and condo associations to support the full SB 4D documentation chain:
- HD Video Camera Inspections: We inspect vertical drainage stacks and provide a digital copy of the inspection video and a written deficiency report suitable for your structural engineer.
- SIRS Reserve Schedule Documentation: We provide remaining useful life estimates and budget figures in a format engineers can use directly in reserve studies.
- Code-Compliant CIPP Lining: All installations use continuous liner methods meeting ASTM F1216 or F1743. We pull all required permits and coordinate post-installation inspections.
- Prior Installation Reviews: If your building had prior lining work done by another contractor, we can inspect and report on its compliance status before you go into a milestone inspection.
We serve Palm Beach, Broward, Miami-Dade, Martin, and St. Lucie counties. Commercial and condo clients only.
