Summer Departure Checklist for Florida Estate Owners

By Nick Martinsen, Owner · Updated August 2026

As spring turns to summer, seasonal residents in Palm Beach Gardens, Boca Raton, and Jupiter head north. Leaving South Florida for the warm months is a cherished routine. Closing a luxury home for five to seven months is not — it takes meticulous care.

Heat, humidity, and severe summer storms do their work quietly. An unmonitored vacant house develops mold, plumbing failures, or pest activity long before anyone opens the front door in the fall. This is the departure checklist we work from.

01

Climate and humidity control

Uncontrolled indoor humidity is the primary cause of mold growth in a vacant Florida home.

Thermostat settings
Set primary A/C thermostats to 75–77°F. If the system has a humidistat, hold it at 50–55% relative humidity.
Air filter replacement
Install fresh high-MERV filters the week you leave, so airflow stays strong through the months the system works hardest.
Ceiling fans
Switch every fan off. In an empty room a motor adds heat and lowers nothing.

02

Plumbing and water risk

A slow supply leak or a running toilet can ruin flooring and cabinetry within days if nobody is there to hear it.

Main water valve
Close the main indoor valve unless a specific system needs pressure — pool auto-fill, fire sprinklers, certain irrigation controllers.
Water heater breaker
Flip the breaker on electric water heaters to off. It saves energy and protects the element if the supply is shut.
Drains and traps
Pour a little mineral oil or white vinegar into sink drains and toilet bowls so trap water does not evaporate and let sewer gas into the house.

03

Appliances and kitchen

Odors and pests both start in the same three places: the refrigerator, the disposal, and the ice bin.

Refrigerator care
For a long departure, clear all perishables. If you empty the appliance entirely, unplug it, clean the interior, and prop the doors open against mildew.
Dishwasher and disposal
Run a cleaning cycle through both, then leave them dry — standing water in a sealed kitchen becomes a smell you will notice in November.
Ice makers
Turn automated ice makers off and empty the bins.

04

Electronics, lighting, and security

Palm Beach County sees more lightning than almost anywhere in the country, and automation racks are expensive to replace.

Surge protection
Unplug non-essential electronics, televisions, and small appliances. Leave surge protection in place on anything that has to stay powered.
Automated lighting
Program smart lighting to realistic daily schedules so the house reads as occupied from the street.
Security monitoring
Give your monitoring company your departure and return dates, and add your local home watch provider to the emergency contact list.

05

Scheduled professional home watch

The single most effective step in protecting an unoccupied Florida estate is a regular, documented inspection schedule.

Insurance requirements
Policies on luxury residences frequently require documented inspections every 7 to 14 days during a long absence. Read yours before you leave, not after a claim.
A written record
Timestamped photo reports after every visit are what turn a problem into a repair rather than an argument with an adjuster.
