What to Do With Utilities When a House Is Vacant
At ASAP Cash Offer, we have inspected, bought, and renovated thousands of empty homes across the United States. We've seen firsthand how a simple oversight with utilities when a house is vacant can turn a profitable asset into a financial nightmare. Whether you are an executor managing utilities during probate for a vacant house (refer to the ABA guidelines on probate), or a landlord with a property between tenants, the decision to cut power isn't as simple as flipping a switch.
Quick answer: Here's what to do with utilities when a house is vacant: keep power on for sump/security, keep heat at 55°F in winter, shut off/drain water if empty more than 48 hours, and call your insurer about the vacancy clause.
What to Do With Utilities When a House Is Vacant (7-Step Checklist)
- Call your insurance agent and ask about the vacancy clause (often 30–60 days).
- Keep electricity ON for sump pump, alarms, cameras, and smart devices.
- Set heat to 55°F in cold months or winterize fully.
- Shut off the main water if the home is empty >48 hours and drain lines.
- Protect P-traps (RV antifreeze/appropriate method) to prevent sewer gas.
- Set summer A/C to 80–85°F to reduce humidity/mold risk.
- Schedule weekly checkups (neighbor/property manager) and document it for insurance.
Drowning in Utility Bills for a House You Don't Live In?
You don't have to keep paying. We buy vacant homes in any condition, covering all closing costs and utility fees.
This comprehensive guide isn't just a generic list; it's the exact protocol we use to protect our own investments. Here is exactly what utilities to keep on in a vacant house to avoid frozen pipes, mold blooms, and insurance denials.
Should Utilities Stay On in a Vacant House?
The Investor's Rule of Thumb
It depends entirely on your exit strategy. If you plan to sell within 90 days, or if the property is in a freezing climate, you must keep utilities on. We have seen countless sales fall through because an inspector couldn't test the furnace, forcing the seller to pay expensive reconnection fees. However, for utilities for an unoccupied house sitting empty for 6+ months in mild climates, you can shut them off—but only after a professional winterization.
Internal Data: The True Cost of Shutting Off Utilities
Based on an April 2026 audit of 814 vacant property acquisitions by ASAP Cash Offer nationwide, the strategy of completely disconnecting utilities yields a negative return on investment for holding periods under 6 months. Our underwriting data shows:
- Homes completely disconnected from climate control for 90+ days sustained an average of $14,200 in preventable secondary damage (primarily drywall buckling and subfloor cupping due to uncontrolled humidity).
- Properties where gas was disconnected required an average 11-day delay in closing due to mandatory municipal pressure tests for reconnection, costing sellers more in holding taxes than the utility savings.

| Probate / Estate | Unknown | Keep ON | Prevents deterioration while legal issues settle. |
| Winter Vacancy | Any | Keep ON | Prevents pipe bursts (unless fully winterized). |
| Long-Term Hold | 6+ Months | Turn OFF* | Save monthly costs (see our full checklist for leaving a house vacant long-term). |
Vacant House Utilities Checklist: The "Big Three"
Following a strict vacant house utilities checklist is your first line of defense. Here is how we handle the critical systems to prevent damage.
Water & Plumbing
The Risk: Burst pipes account for the majority of insurance claims in vacant homes.
- Shut Off Main: If empty >48 hours, close the main valve.
- Bleed Lines: Open top and bottom faucets to drain pipes.
- Seal Drains: Pour 2 tbsp vegetable oil (Summer) or RV Antifreeze (Winter) in drains to block sewer gas.
Gas & Heating
The Risk: Frozen pipes inside walls or mold growth from humidity.
- Winter Temp: Set to 55°F (13°C). Never lower.
- Summer Temp: Set to 80-85°F to control humidity.
- Pilot Lights: Leave water heater on "Vacation" mode to prevent tank freezing.
Electricity
The Risk: Sump pump failure leads to flooded basements. Always consult the FEMA flood maps to determine if your vacancy requires high-capacity backup power.
- Sump Pump: MUST stay powered on.
- Security: Keep Wi-Fi on for cameras.
- Vampire Loads: Unplug TVs and microwaves to save $10-20/month.
Why "Just Turning It Off" Is Dangerous
Many homeowners assume that managing power in a vacant house is as simple as calling the utility company and canceling service. In our experience, this often leads to three specific types of expensive damage.
1. The Sump Pump Paradox
If your home has a basement, it likely has a sump pump. That pump requires electricity. We have purchased dozens of homes where the previous owner saved $30 by turning off the electricity, only to cause $20,000 in basement flooding damage after a heavy rainstorm. Never flip the main breaker if you have a sump pump.
Devon's Field Note
April 14, 2026 | Logan Square, Chicago, IL"I walked a probate property this morning where the executor cut the power in November to save money. When the March thaw hit, the unpowered sump pump flooded the basement with 4 inches of standing water. Worse, because the water was shut off, the P-traps under the sinks evaporated completely, filling the main floor with the unmistakable stench of hydrogen sulfide (sewer gas). The decision to save $45 a month on the ComEd bill resulted in a mandatory $22,000 mitigation line item on our cash offer today. Keep the power on."
2. The "Sewer Gas" Effect
Water safety in a vacant home isn't just about leaks; it's about what comes up the pipes. The "P-traps" under your sinks rely on standing water to block sewer gas. In a vacant house, this water evaporates in about 3 weeks. Once it's gone, your house will fill with methane gas. Exposure to hydrogen sulfide and methane from sewer gas is a documented health hazard involving respiratory and neurological risks (CDC NIOSH exposure data).
3. The Mold Incubator
In humid climates (like the South or Midwest summers), an air conditioner does more than cool; it dehumidifies. If you turn off the electricity in July, the internal humidity can spike to 90%. We've seen drywall absorb this moisture and buckle, and hardwood floors "cup" and warp. Keeping the AC on at 85°F protects the structural integrity of the home.
Can You Pause or Suspend Utility Service on a Vacant Home?
If you are wondering, "can I pause my electricity service if my home is vacant?" the answer is generally yes, but it comes with strict conditions. A vacant homeowner can pause electric service via a seasonal suspension, which temporarily halts billing without closing the account entirely. This is an option provided by many utility companies to accommodate snowbirds, probate properties, and major renovations.
Requesting a Seasonal Suspension
Most utility providers offer a "vacation" or "seasonal" rate that allows you to pause service for 30 to 90 days. During this period, you will typically pay a reduced base connection fee (usually $10 to $25 per month) rather than the standard flat rate and usage charges. To set this up, you must call your utility provider's customer retention or moving department and explicitly ask for a seasonal suspension, rather than a full disconnection.
The Risks of Reconnecting Service
While a seasonal suspension is straightforward, a complete disconnection is not. If you fully shut off your utilities and later need to turn them back on to sell or lease the property, you will face reconnection fees. More importantly, if your gas service is disconnected for more than six months, local municipalities typically require a licensed plumber to perform a pressure test before the utility company will restore service. This can cost upwards of $500 and delay your timeline.
Devon's Field Note
October 22, 2025 | Phoenix, AZ"An inherited property seller in Scottsdale decided to fully cancel their SRP electric and Southwest Gas accounts to save $120 a month during a prolonged probate. Seven months later, when the buyer's inspector arrived, we couldn't turn the utilities on. The gas company mandated a full line pressure test due to the length of the disconnect. The seller ended up paying a plumber $650 and delayed closing by two weeks. Always ask for a seasonal suspension instead of a hard cancellation."
Vacant vs. Unoccupied: The Insurance Definition
This is the most critical financial risk regarding unoccupied home utilities. Standard homeowner insurance policies distinguish between these two states:
- Unoccupied: The home is ready for immediate use. Furniture remains, and utilities are active. The owner is away temporarily (vacation, hospitalization).
- Vacant: The property is empty of inhabitants and personal possessions. There is no intent for immediate habitation.
According to NerdWallet, carriers often limit or void coverage after 30–60 days of vacancy. If a pipe bursts or vandalism occurs on Day 31 and you didn't buy a "Vacancy Permit," your claim will likely be denied.
Crucial Action: You must notify your insurer in advance if the property will be empty for more than 30 days. According to the Insurance Information Institute (III), standard policies often automatically remove coverage for glass breakage and water damage once the vacancy clause is triggered.
Security & Smart Tech for Vacant Homes
Managing power in a vacant house allows you to leverage modern technology to replace a physical presence. If you live out of state, we recommend a "Low-Tech + High-Tech" approach.
- Wi-Fi Freeze Alarms ($30): These small devices alert your phone if the temperature drops below 50°F, giving you time to act before pipes freeze.
- Smart Plugs ($10): Put two lamps on smart plugs. Set them to turn on at random intervals in the evening. A constantly dark house is a beacon for squatters; a house with fluctuating light looks lived-in.
- Video Doorbells: Squatters often "test" a house by ringing the doorbell to see if anyone answers. Answering remotely via your phone can be enough to deter a break-in.
Worried About Squatters or Break-ins?
Empty houses are magnets for trouble. Sell your vacant property "As-Is" to us, and we'll take over the security, insurance, and utilities immediately.
Selling a House with Utilities Off
Can you sell a house if the water and lights are off? Yes, but it significantly shrinks your buyer pool.
Traditional Buyers (FHA/VA Loans)
For buyers using FHA or most traditional bank financing, utilities typically must be active so systems can be properly observed and tested by the appraiser. In many cases, appraisals are made "subject to" utilities being activated before final loan approval.
Regarding VA loans, while the property must meet strict Minimum Property Requirements (MPRs), VA appraisers generally do not test mechanical systems. Consequently, electricity and other utilities may not strictly be required to be on at the time of the VA inspection, though the home must ultimately have functional service to close.
The Cash Buyer Advantage
This is where ASAP Cash Offer is different. We buy homes "As-Is." We don't need to turn on the water to know the plumbing might need work. We don't need to test the furnace to know it might be old. We assume those risks so you don't have to.
Selling to ASAP Cash Offer means:
- No reconnection fees.
- No cleaning out the "sewer smell."
- No waiting for inspections.
- Closing in as little as 7 days.
