A burst pipe in a single-family home is bad. The same burst pipe in a 40-unit condo building, a strip-mall restaurant, or a 4,000-square-foot office floor is exponentially worse. There are tenants, employees, customers, business income to protect, multiple insurance policies in play, and a much narrower window before secondary damage becomes its own crisis.
This is the post we wish every Miami, Fort Lauderdale, Boca Raton, and Palm Beach property manager, HOA board member, condo owner, and small-business owner read before they had a water event in their building. The principles overlap with residential restoration, but the execution is meaningfully different.
Why commercial events are different
Three structural differences that change everything:
1. Multiple stakeholders. A residential event has one homeowner and one insurance carrier. A commercial event has the property owner, property management company, HOA or condo association, individual unit owners, tenants, business owners, two or three insurance policies stacked on top of each other, and sometimes a lender.
2. Business income is at stake. If a restaurant is closed for two weeks, that's $20K–$100K in lost revenue. The restoration scope and timeline aren't just about repair — they're about getting the operation back up.
3. Timing matters more. Residential restoration can be flexible — work around the homeowner's schedule. Commercial restoration usually has a hard deadline tied to a tenant lease, a business reopening, or an event. The drying timeline cannot slip.
A commercial water event needs a restoration company that has done commercial work before, has the equipment to scale, and knows how to move fast under coordinated leadership.
The first 4 hours: priority order
A commercial water event in the first 4 hours has a specific priority order:
1. Stop the source. Building maintenance or a plumber. Whoever has the master valve.
2. Notify the right people. Property manager, HOA, building owner, tenants in affected units, business owners. Don't let people walk into the situation cold.
3. Cut power if water is anywhere near electrical. A flooded electrical room or wet panel is a life-safety issue, not just a property issue.
4. Get a restoration company on site. Commercial response should be on site within 60 minutes in most South Florida service areas.
5. Containment. Plastic sheeting, zip walls, and signage to keep tenants and customers out of the affected area.
6. Document. Time-stamped photos and video before any cleanup. The number of insurance disputes after a commercial event is roughly 3x the residential rate, and documentation is the difference.
7. Notify the carriers. Building policy, condo association master policy, individual unit policies, and any business policies all in parallel.
Common commercial water sources we respond to
The patterns we see most:
- Burst supply lines in mechanical rooms or above ceilings. A broken pipe above a drop ceiling can put water across an entire floor before anyone notices.
- Sprinkler system failure. Either a real fire activation that flooded a whole floor, or a maintenance event (a hit sprinkler head, a frozen line in a refrigerated space, a corroded valve).
- Roof leak in a flat-roof commercial building. TPO and modified bitumen roofs fail at seams and penetrations. Water travels along the deck before it shows up.
- Toilet or sink overflow on an upper floor of a condo. Travels through floor assemblies and damages multiple units below.
- HVAC condensate failure in a large rooftop unit with the drain tied into the building's drain system.
- Storm damage — wind-driven rain or surge.
- Vehicle into the building. A car through a storefront window during a storm sounds rare but we've responded to several in South Florida.
Each source has its own playbook for diagnosis and immediate mitigation.
Why HOA and condo claims are uniquely complicated
In a condo or HOA building, there are typically three different insurance layers:
- The master policy held by the association covers the building structure (typically the bare walls or all-in depending on the policy and the state).
- The individual unit owner's HO-6 policy covers everything inside their walls.
- Tenant or renter policies if applicable.
A water event that originates in one unit and damages multiple units below has all three layers in play. Who's responsible for what:
- The unit where the event started — their HO-6 typically covers their unit damage; they may also be liable for damage they caused to other units.
- The damaged units below — their HO-6 covers their unit damage.
- Common areas (hallway, structure, exterior walls) — master policy.
- Loss assessments — if the master policy doesn't cover something and the association assesses unit owners, the HO-6 loss assessment coverage may pay.
This gets complicated fast. The restoration company doesn't sort it out, but a good one will produce documentation that lets the parties' carriers sort it out without dragging on for months.
The most common condo restoration mistake is starting work before insurance is engaged. Carriers may decline to cover work performed before their adjuster has seen the loss. Always loop the carriers in first, even at 2 AM.
Why timing matters: business income and tenant displacement
The hidden cost in any commercial water event is what's not happening while the building is being restored:
- A restaurant loses $5K–$15K a day in revenue if it's closed.
- A medical office loses scheduled appointments and may not be able to reschedule them.
- A retail tenant may have a lease clause that lets them break the lease if the space is unusable beyond a certain duration.
- An office tenant has employees who can't work productively from home for long periods, and may relocate temporarily.
Most commercial policies include Business Interruption coverage, but the calculation requires documentation of normal revenue, rebuild timeline, and reopening. A restoration company that understands business interruption documentation is materially more valuable than one that just dries the building.
The drying-fast vs. drying-right tradeoff is sharper here. Residential drying can take 5–10 days because the homeowner can wait. Commercial drying often needs to happen in 3–5 days because the lost-revenue clock is ticking. This requires more equipment, faster turnover, and coordination that a small residential operator can't pull off.
What proper commercial restoration looks like
A real commercial scope:
- Rapid response — on-site within 60 minutes, multi-truck if the loss is large.
- Containment — zip walls, signage, foot traffic protection, OSHA-compliant if employees are in the building.
- Scaled equipment — desiccant dehumidifiers (not just refrigerant), commercial truck-mounted extraction, large-scale air movers. A 5,000-square-foot wet area needs 50+ pieces of drying equipment, not 6.
- 24/7 monitoring — most serious commercial dries run continuous monitoring with daily moisture logs.
- Coordinated demolition — drywall, ceiling tiles, flooring, cabinetry as needed, with care to preserve what can be saved.
- Mold remediation if mold is present, under the IICRC S520 standard.
- HVAC decontamination — the building HVAC system pulls contamination through the entire floor if not addressed early.
- Reconstruction with a project manager coordinating multiple trades.
- Building income / continuity coordination — temporary tenant relocation if needed, tenant communications, lease coordination with property management.
A residential restoration company doing their first commercial job is going to underscale the equipment and miss the timing. Hire someone who's done this before.
Insurance considerations
A few commercial-specific insurance points:
- Master policies often have higher deductibles than individual HO-6s — sometimes a $25K or $50K wind deductible.
- Some master policies exclude water damage that originates inside individual units (it's the unit owner's responsibility under their HO-6).
- Business income coverage has waiting periods (often 72 hours) before it kicks in.
- Some commercial policies require specific notice procedures within 24 or 48 hours of the loss.
- Tenants' personal property is on their own renters or business policy, not the building's policy.
If you're a property manager or HOA board member, understand your master policy before you have an event. If you're a unit owner, understand your HO-6. If you're a tenant, understand your renters or business policy.
