On June 24, 2021, Champlain Towers South collapsed in Surfside, Florida, killing 98 people. The investigation revealed structural deterioration that had been documented but never adequately addressed. In response, the Florida Legislature passed Senate Bill 4-D, creating mandatory structural inspections for condo and cooperative buildings across the state.

The law, codified in Florida Statute 553.899, requires "milestone inspections" -- professional structural evaluations performed by licensed engineers or architects. For many buildings, the deadline is December 31, 2026. Missing it can mean $500/day fines, code compliance referrals, and even evacuation orders.

This guide covers everything your board needs to know: who's affected, when your inspection is due, what it costs, how Phase 1 and Phase 2 work, and how the milestone inspection connects to the SIRS reserve study requirement.

Who needs a milestone inspection

Under FL 553.899, milestone inspections are required for:

The law does not apply to single-family homes, duplexes, triplexes, or buildings with fewer than three habitable stories above ground.

How to count stories

The statute specifies "habitable stories above ground." A parking garage level is generally not considered a habitable story. If your building has a ground-floor parking podium with three residential floors above, it may qualify. Your local building department makes the final determination.

When is it due

The deadline depends on two factors: your building's age (based on the certificate of occupancy date) and its distance from the coastline.

Location First inspection due Subsequent inspections
Within 3 miles of coastline By Dec 31 of the year the building turns 25 years old Every 10 years
More than 3 miles from coastline By Dec 31 of the year the building turns 30 years old Every 10 years
CO issued on or before July 1, 1992 Was due by Dec 31, 2024 Every 10 years
How to find your building's certificate of occupancy date

Contact your local building department. The CO date determines your deadline. If the CO date is unavailable, the building department will use the earliest occupancy date from their records. Some counties have online permit databases where you can search by address. The City of Tampa and other municipalities maintain searchable inspection registries.

Phase 1 vs Phase 2: what's the difference

The milestone inspection has two potential phases. Phase 2 is not automatic -- it's only triggered if Phase 1 finds problems.

Phase 1: Visual examination
  • Licensed engineer or architect visually inspects all structural components
  • Evaluates load-bearing walls, columns, beams, floors, foundations, and primary structural systems
  • No destructive testing -- visual only
  • If no substantial structural deterioration is found, the process is complete
  • Report filed with building department + distributed to owners
Phase 2: Testing and investigation
  • Only triggered if Phase 1 identifies substantial structural deterioration
  • May involve concrete coring, exploratory openings, and material testing
  • Confirms the extent of deterioration and whether it poses a safety threat
  • Test locations chosen for minimal disruption (per statute)
  • Repairs must begin within 365 days of receiving the Phase 2 report

"Substantial structural deterioration" is defined as deterioration that compromises a building component's structural capacity to the extent that it poses a threat to health, safety, or welfare. Minor cosmetic cracking or surface wear typically does not trigger Phase 2. This is a professional engineering judgment.

What it costs

The cost varies significantly based on building size, age, complexity, and location. South Florida counties (Miami-Dade, Broward) tend to run higher due to salt air exposure and demand for engineers.

Building size Phase 1 cost Phase 2 cost (if triggered)
Small (10-30 units) $8,000 - $25,000 $40,000 - $100,000
Mid-size (30-100 units) $20,000 - $60,000 $60,000 - $150,000
Large high-rise (100+ units) $50,000 - $150,000+ $100,000 - $250,000+

The association is responsible for the cost. For many buildings, this will require a special assessment or reserve draw. Factor this into your reserve planning now rather than scrambling at the deadline.

Hiring the right engineer

The inspection must be performed by a Florida-licensed professional engineer or architect. Get at least three proposals. Ask specifically about their experience with Florida milestone inspections under 553.899 -- this is specialized work, and not every structural engineer has done them. Verify their license at myfloridalicense.com.

The board's step-by-step process

Here's the timeline your board must follow once notified that a milestone inspection is due:

1. Receive notice from the building department

Your local enforcement agency sends written notice by certified mail that a milestone inspection is required. This notice goes to the association and any non-association building owners.

2. Notify all unit owners within 14 days

Within 14 days of the county's notice, the board must alert all owners of the inspection requirement and the deadline. This is a statutory obligation under 553.899 -- don't skip it. Owners have the right to access all official records related to the inspection, so transparent communication from the start prevents disputes later.

3. Hire a licensed engineer or architect

Engage a Florida-licensed professional to perform the Phase 1 inspection. Budget 2-4 months for scheduling, especially if you're in South Florida where demand is high.

4. Complete Phase 1 within 180 days

The association must complete Phase 1 within 180 days of receiving the building department's notice. Plan ahead -- many engineers are backlogged, and waiting until the last minute risks missing the statutory window.

5. File the report and distribute within 45 days

Within 45 days after the engineer delivers the completed report, the board must:

6. If Phase 2 is required: begin repairs within 365 days

If Phase 1 triggers Phase 2 and structural deficiencies are confirmed, repairs must commence within 365 days of receiving the Phase 2 report -- unless the local building department requires an earlier start.

Milestone inspection + SIRS: how they connect

The milestone inspection and the Structural Integrity Reserve Study (SIRS) are separate legal requirements, but they overlap significantly and can be coordinated to save time and money.

Milestone inspection SIRS
Governed by FL 553.899 FL 718.112(2)(g)
Purpose Structural safety evaluation Reserve funding plan for structural components
Applies to Condos and co-ops, 3+ stories All condos (regardless of height)
Frequency Every 10 years after initial Every 10 years
Can be done simultaneously? Yes -- if both are due by Dec 31, 2026, they can be completed together
Cost savings A milestone inspection completed within 5 years can replace the visual inspection portion of the SIRS

If your building needs both by December 31, 2026, coordinate them with a single engineering firm. You'll reduce access disruptions, save on mobilization costs, and ensure both reports use consistent findings.

What happens if you miss it

The consequences of non-compliance are serious and escalating. Missing the deadline doesn't just mean a fine -- it can mean your residents are forced to leave the building.

Penalties for non-compliance

Board members should understand that the business judgment rule will not protect them here. Failing to schedule a legally required inspection is not a judgment call -- it's a statutory violation. If your building is approaching the deadline and the board hasn't acted, individual directors face personal exposure.

Frequently asked questions

It depends on your building's age and location. Coastal buildings (within 3 miles) must be inspected by December 31 of the year the building turns 25. Inland buildings have until 30 years. The age is based on the certificate of occupancy date. Contact your local building department to confirm your deadline.
Phase 1 ranges from $8,000-$25,000 for small buildings to $50,000-$150,000+ for large high-rises. Phase 2 (if triggered) can cost $40,000-$250,000+. South Florida tends to be at the higher end due to demand and coastal conditions.
Phase 1 is a visual examination of structural components. If no substantial deterioration is found, you're done. Phase 2 is only triggered if Phase 1 identifies structural problems -- it involves destructive and nondestructive testing to confirm the extent of the issue. Repairs must begin within 365 days of the Phase 2 report.
Fines of $500+/day, code compliance referrals, potential vacate orders, DBPR reporting, and personal liability for board members. This is not a discretionary requirement -- it's a statutory mandate with enforcement teeth.
Yes. If both are due by December 31, 2026, Florida law allows them to be completed simultaneously. A milestone inspection within the past 5 years can also replace the visual inspection portion of the SIRS. Coordinate with a single engineering firm to save on costs.
