Home Utility Shutoff Checklist: Water, Electricity, and Gas
Locate and label the water main, electrical panel, and gas utility controls before an emergency. Learn the building-specific procedure from the utility or qualified professional, keep the correct tools accessible, and never turn gas back on yourself after an emergency shutoff.
What to know
- The street-side water valve, meter equipment, and utility-owned gas components may require special tools or utility authorization.
- Electricity should not be approached when water, smoke, arcing, or structural damage makes the panel unsafe.
- Ready.gov warns that only a qualified professional should restore gas after it has been shut off for an emergency.
A utility shutoff is useful only when the household knows where it is, what it controls, and whether it is safe and legal to operate. Do the identification and documentation while the building is dry, powered, and calm—not during a flood or gas odor.
Create a one-page utility map
Record the location of the main water shutoff, electrical service panel, gas meter or emergency control, heating-fuel shutoff, and any building-specific controls. Add a simple floor-plan sketch and photographs that show the path to each location.
Include utility emergency telephone numbers, landlord or property-manager contacts, electrician, plumber, and heating-service contacts. Store a paper copy with the emergency documents and a private digital copy.
Do not publish photographs that reveal home access, security systems, account numbers, or utility identifiers.
Identify the main water shutoff
Follow the incoming water line from where it enters the building. The interior main valve may be near the meter, basement wall, crawlspace, mechanical room, or utility closet. Label it clearly without covering inspection or meter information.
Ready.gov recommends locating the household water shutoff, making sure responsible household members know where it is, and confirming that it can close fully. [1]
Do not confuse the household valve with a street-side or curb valve. Utility-owned valves may require special tools and authorization. For a rental or multifamily building, ask management which valve residents may operate.
Exercise an old valve only when a plumber or utility says it is appropriate. A corroded valve can begin leaking when disturbed.
Prepare for a water emergency
Keep the correct user-approved tool nearby if the valve needs one. Record which direction closes it. Test labels and lighting, not the emergency itself.
Shut off the household water for a burst pipe or uncontrolled leak when you can reach the valve safely. Then address electricity near the water, notify responsible parties, and arrange repair. Do not enter water that may be energized.
Document the electrical panel
Make sure the panel is accessible, dry, and not blocked by storage. Label every branch circuit using an orderly mapping process. Record the main disconnect location and whether it is inside, outside, or part of service equipment.
Ready.gov advises responsible household members to know how to shut off electricity and notes a sequence of switching individual circuits off before the main. [1] Follow the specific panel, utility, and emergency instructions for your property.
Never remove the panel cover, touch service conductors, or approach the panel during flooding, smoke, arcing, heat, or structural damage. Parts may remain energized even after a main disconnect is operated.
Treat gas differently
Locate the gas meter from a safe distance and obtain the utility’s emergency instructions. Do not practice turning the gas off merely to prove you can. Some valves require a wrench, and shutting off service may create testing and relighting requirements.
If you smell gas or hear hissing, leave the building promptly, avoid switches, phones, flames, vehicles, and sparks in the affected area, and call the gas utility or emergency services from a safe location.
Ready.gov states that if gas is shut off for an emergency, only a qualified professional should turn it back on. [1]
Do not store a tool where reaching it would require approaching a suspected gas leak.
Include other systems
Record oil or propane supplier contacts, well-pump disconnects, solar and battery-system emergency labels, fire-sprinkler controls, sump-pump power, and heating-system emergency switches where present. Follow installer and fire-department instructions; do not shut off fire protection casually.
Practice decisions, not hazardous operation
Walk household members through the map. Use scenarios: leaking washer hose, burning electrical odor, gas smell, flooded basement, evacuation order. The correct answer may be to leave and call professionals rather than touch a control.
Update the map after renovations, utility work, a move, or new equipment. The goal is not to make every resident a utility technician. It is to prevent panic, misidentification, and dangerous improvisation.
Limits and cautions
- Shutoff location, ownership, valve type, panel design, utility procedure, landlord responsibility, and emergency instructions vary by property and jurisdiction.
