Snowbird Seasonal Home Shutdown: The Complete Cabo Open-and-Close Checklist

Closing up your Cabo home for the summer and reopening it in the fall is not the same as locking the door on a condo in Phoenix. The combination of 90°F heat, 80% humidity, hurricane season, and six months of vacancy creates problems that can cost you thousands — or ruin irreplaceable items — if you do it wrong. Here is the snowbird seasonal home shutdown checklist I have built from walking into too many properties that were left to fend for themselves.

The Spring Shutdown: Closing Your Cabo Home (April–May)

Most snowbird owners head north between late March and early May. The goal is to leave your property in a state that can survive six months of extreme heat, humidity, potential storms, and limited oversight. Do not rush this — budget a full day for the shutdown.

Water Systems

• Water heater: Set to vacation mode or pilot only. Do not turn it completely off if you have a tank-style heater — stagnant water in a hot tank breeds legionella bacteria. If you have a tankless on-demand heater, turn it off at the gas valve and the power
• Flush all drains: Run water through every sink, shower, and toilet to fill the P-traps. Dry P-traps allow sewer gas — and insects — to enter the house. Pour a tablespoon of mineral oil in each drain to slow evaporation over the summer
• Cistern: If your property has a cistern (most standalone homes in Cabo do — see our cistern guide), either fill it completely and add a chlorine treatment tablet, or drain it completely. A half-full untreated cistern in 90°F heat is a mosquito breeding operation
• Shut off the main water valve: This prevents a slow leak from becoming a catastrophic flood while you are gone. Tell your caretaker where the valve is and how to reopen it for inspections
• Washing machine: Run an empty hot cycle with vinegar, then leave the door open. A closed front-loader in Cabo humidity will grow mold within two weeks

Electrical and Climate Control

This is where most owners make the critical mistake. They turn everything off to save on the CFE electric bill. Then they return in October to a home full of mold.

• Leave at least one mini-split running: Set it to dry mode (dehumidification) at 78°F (25°C). The electricity cost is about 500–800 MXN/month ($28–$45 USD). The mold remediation cost if you do not is $2,000–$10,000 USD. The math is not complicated
• Refrigerator: Clean it out completely. Either unplug it and leave the doors propped open, or leave it running empty at a moderate setting. I prefer leaving it running — the small electricity cost prevents the rubber seals from drying out and cracking in the heat
• Unplug everything else: TVs, sound systems, coffee machines, chargers. Cabo gets sporadic power surges, and a surge on an unoccupied home can fry electronics. Use surge protectors on anything you leave plugged in
• Circuit breakers: Leave the main on (for the AC and fridge) but turn off circuits for unused rooms, outdoor lighting, and water features

Hurricane Preparation

Hurricane season overlaps directly with the snowbird absence period — June 1 through November 30. Hurricane prep for an unoccupied home requires planning:

• Store or secure all outdoor furniture: Bring patio furniture, cushions, planters, and anything loose indoors or into a locked storage area. A patio chair in 120 mph winds becomes a projectile
• Window protection: If your property does not have hurricane shutters, have your caretaker install plywood covers before a storm warning. Ensure you have pre-cut plywood sized for every window stored on-site, and screws and a drill for the caretaker to install them. Leave the plywood labeled by window for quick installation
• Roof drains: Clear all roof drains and gutters before departure. A clogged drain on a flat roof during a tropical storm creates a ponding load that can collapse the structure
• Insurance documentation: Photograph every room and all exterior surfaces before you leave. Store the photos in the cloud. Update your insurance policy to ensure it covers named storms and has a current replacement valuation

Hiring a Caretaker

A caretaker is not optional for a snowbird-occupied Cabo property. Full stop. Six months of absence in this climate without regular human eyes on the property is a guarantee of problems.

Professional caretaker services in Los Cabos typically cost:

• Weekly inspection (exterior + basic interior): 3,000–5,000 MXN/month ($165–$275 USD)
• Full-service caretaker (weekly inspection + gardening + pool + systems check): 5,000–8,000 MXN/month ($275–$440 USD)
• Live-in caretaker/property guardian: 8,000–15,000 MXN/month ($440–$825 USD) — typically for large villas

Your caretaker should provide:

• Weekly photo documentation of the interior and exterior, sent to you via WhatsApp or email
• Monthly running of all faucets, showers, and toilets to maintain P-traps and check for leaks
• AC filter inspection and replacement as needed
• Pest inspection (see below)
• Storm response — boarding windows, securing loose items, post-storm damage assessment
• Coordination with any vendors (pool service, gardener, pest control) that visit the property

If your property is in a gated community like Pedregal or Palmilla, the HOA may provide some level of exterior oversight, but it does not replace a caretaker who enters the unit and checks the interior. HOA security guards check that your gate is locked. They do not check that your closets are not growing mold.

Pest Control During Vacancy

An unoccupied home in Baja California Sur is an invitation for every insect, scorpion, and gecko in the desert. The specific pests vary by location — San Jose del Cabo properties near the estuary deal with more mosquitoes; inland El Tezal properties see more scorpions — but the protocol is the same.

• Before departure: Have a professional pest service treat the interior and exterior perimeter. Cost: approximately 1,500–3,000 MXN ($85–$165 USD) per treatment
• During absence: Monthly perimeter treatment by the pest company, coordinated with your caretaker to provide access. Budget 800–1,500 MXN/month ($45–$85)
• Seal entry points: Caulk gaps around pipes, drains, and AC line penetrations. Scorpions can enter through a gap the width of a credit card
• Food storage: Leave absolutely zero food in the pantry. No canned goods, no spices, nothing. Even sealed packages attract rodents over six months. Donate or take everything

The Fall Startup: Reopening Your Cabo Home (October–November)

Most snowbirds return between mid-October and early November. Your startup checklist is the reverse of the shutdown, but with some additions:

First 24 Hours

• Inspect before you unpack: Walk every room. Check ceilings for water stains. Open every closet. Look under sinks. Check the roof for storm damage. Look for pest evidence
• Turn on the water main and check for leaks: Open the valve slowly. Walk the property and check every fixture, the water heater, and the cistern for leaks before running the water at full pressure
• Flush the system: Run all faucets and showers for 2–3 minutes to clear stagnant water from the lines. You may see discolored water initially — this is normal
• Water heater: Bring it back to operating temperature. Check the pressure relief valve
• AC systems: If they have been running on dry mode, switch to normal cooling. Check filters and clean or replace them. Listen for unusual noises from the compressor
• Appliances: Plug everything back in. Run the dishwasher and washing machine empty to flush their lines. Check the oven for any pest nesting

First Week Tasks

• Deep cleaning: Budget for a professional deep clean. After six months of dust accumulation and whatever the humidity has done, a thorough cleaning is necessary. Cost: 2,000–5,000 MXN ($110–$275 USD) depending on property size
• Vehicle: If you left a vehicle, check the battery (it will likely be dead), tire pressure, fluid levels, and look for any pest or rodent damage under the hood. Have a mechanic inspect it before driving
• Systems check: Test all smoke detectors, CO detectors, security cameras, and alarm systems. Replace batteries in everything
• Garden and exterior: Assess the landscaping. Six months of Cabo summer sun with limited watering will stress even drought-tolerant plants. Your gardener should resume regular service before your arrival

Remote Monitoring Options

Technology has made snowbird ownership significantly easier. Here is what I recommend for remote monitoring:

• Wi-Fi security cameras: Interior and exterior cameras with cloud storage. Ring and Wyze cameras work in Mexico and cost $30–$100 per camera. Keep your internet service active year-round for this to work
• Water leak sensors: Place wireless leak sensors under sinks, near the water heater, near the washing machine, and at the cistern. A $20 sensor can save you $20,000 in water damage
• Smart plugs with energy monitoring: See which devices are drawing power and turn things on/off remotely
• Temperature and humidity sensors: Monitor interior conditions. If humidity spikes above 70%, you know the AC has stopped working and can alert your caretaker

The total internet cost to keep connectivity running year-round in Cabo is approximately 500–800 MXN/month ($28–$45 USD) for basic fiber or cable service. See our connectivity guide for provider options.

Insurance and Legal Considerations

Extended vacancy can affect your property insurance. Most policies have a vacancy clause — typically 30 to 60 days of continuous vacancy before coverage restrictions apply. Key steps:

• Notify your insurer: Tell them the property will be seasonally unoccupied. Ask about vacancy endorsements
• Caretaker visits count: Regular documented visits by a caretaker may satisfy the "not vacant" requirement for many policies. Keep records
• Rental option: Some owners put their property on the vacation rental market during the summer months to avoid vacancy entirely. Occupancy generates revenue, keeps the home maintained, and satisfies insurance requirements. The trade-off is wear and tear from guests

Seasonal Budget Summary

Here is the total annual budget for a snowbird who occupies their Cabo home from November through April and closes it May through October:

This is the cost of protecting your investment. The cost of not doing it — mold remediation, water damage repair, pest infestation cleanup, or hurricane damage to an unprotected property — is an order of magnitude higher. I have seen owners spend $15,000 repairing damage that a $3,000 annual seasonal maintenance budget would have prevented entirely.
