In the Keys, the building code decides more of your exposure than the contract does.
Contractors working Monroe County operate under a set of constraints that do not exist on the mainland. Everything arrives down one road. Flood elevation governs what can be built and what can be repaired. And a rule most owners have never heard of can turn a renovation into a reconstruction partway through the job.
That last one is where contractors get caught, because the person who finds out is usually you, standing in a house you have already opened up.
The fifty percent rule is a contractor’s problem before it is an owner’s
In a mapped flood zone, if the cost to repair or improve a structure reaches roughly half of its market value before the work, local floodplain rules generally require the whole building to be brought into compliance with current requirements rather than simply restored.
In the Keys, where a great deal of the housing stock predates current elevation standards, that frequently means the structure has to be elevated. A kitchen and bath renovation becomes a reconstruction with a new foundation, new utilities, and new access.
Three things follow for a contractor.
The determination is made by the floodplain administrator, not by you or the owner. It is worth establishing where a project sits relative to the threshold before you write the contract, not after the permit is reviewed.
Some jurisdictions count improvements cumulatively over time, so a client who has done several smaller projects may already be closer to the line than either of you realize.
Your contract should say what happens if the determination changes the scope. A job that stops mid-course because compliance is now required is a dispute waiting to happen, and it is the sort of dispute that produces a claim against your professional or general liability rather than a simple change order.
Our guide to FEMA’s fifty percent rule in Monroe County covers the mechanics in more detail.
Your general liability does not pay to redo your own work
This is the most expensive misunderstanding in the trades and it applies everywhere, but it lands harder here because rework in the Keys costs more than rework anywhere else.
If your installation fails and damages the building around it, your general liability generally pays for that damage. It does not pay to replace your own defective work, because your workmanship is what you were paid to get right.
What matters more is products and completed operations coverage, which responds to work you finished that fails later. Check that it is actually included rather than stripped out, and look at the aggregate, since that is the ceiling across all such claims in a year.
One road changes the time on everything
Materials, specialty trades, equipment, and inspections all arrive from the mainland. That affects your business in three ways worth insuring against.
Schedules run long, which raises the odds of a liquidated damages provision biting on a commercial contract. Read those clauses before you sign.
Your own tools and equipment travel constantly, which is what contractors equipment coverage on an inland marine form exists for. Confirm how it treats theft from an unattended vehicle, and whether high value items need scheduling separately.
If your own yard or shop is damaged, the contractors who would repair it are coming from Homestead and they are booked. Business income coverage needs a longer period of restoration here than the same policy would need in Miami.
Certificates are the gate on the job
Whether you sub for a general contractor, work for a property manager, or bid municipal and county work, no certificate means no site access.
The requirements are specific: additional insured status for ongoing and completed operations, primary and noncontributory wording, and a waiver of subrogation. Each of those requires an endorsement that has to be on the policy rather than typed onto the certificate. A certificate promising coverage the policy does not contain protects nobody, and the contractor holding it is the one exposed.
Our clients handle certificates themselves through our service center. Once the account is set up you can add a new certificate holder and issue the certificate at any hour, without waiting on our office. That covers a standard certificate showing coverage you already carry; anything requiring special wording or a coverage change comes through us, because those are changes to the policy rather than to the certificate.
Subcontractors, and what happens at audit
If you sub out any portion of a job, that sub’s certificate protects you. If you cannot produce one, your own carrier will treat that sub’s cost as your payroll at audit, and the bill arrives months after the job closed.
Your general liability premium is auditable against payroll or receipts, and so is your workers’ compensation. Reporting honestly through the year costs considerably less than settling up at the end of it.
Florida also treats construction-classified work differently from other industries for workers’ compensation, and the exemptions available to owners and officers are narrower than many contractors expect. If you carry an exemption or believe you do not yet need coverage, confirm it rather than assuming — it affects both your legal exposure and your ability to work for any general contractor who checks.
Working on or over water
A large share of Keys construction happens at the waterline — docks, seawalls, boat lifts, davits, boathouses, and repairs to structures over water.
Two things change when it does. Employees working on or near navigable waters can fall under federal maritime compensation law rather than Florida’s system, and a state workers’ compensation policy without the federal endorsement may not respond to their injury. And work in sanctuary waters carries pollution and environmental exposure that a standard contractor’s policy excludes.
If any part of your work happens over water, those need to be addressed specifically rather than assumed.
Storm season is a contract question as much as a coverage one
Open work in progress is exposed when a storm comes, and who bears that risk depends on what the contract says.
Builders risk covers the project during construction, and on a Keys job it should reflect both the value at risk at peak and the reality that a damaged project takes longer to resume here than on the mainland. Confirm who is required to carry it, what perils it covers, and whether flood and named windstorm are included or excluded.
The same applies to your own materials on site and to anything you have staged but not installed.
What we write in the Keys
Prestige Insurance Group places contractor coverage throughout Key Largo, Tavernier, Islamorada, Marathon, Big Pine, and Key West.
The trades include general contractors, remodelers, carpenters, electricians, plumbers, HVAC, roofers, concrete and masonry, pool contractors, dock and seawall builders, painters, flooring and tile, and mobile and service operations.
Keys work is underwritten differently from mainland work because the exposures are different, and a policy assembled for a Miami contractor does not automatically fit a Monroe County one.
