How to Build a New-Home Emergency Contact List in 30 Minutes

TL;DR: Every homeowner needs an emergency contact list with six categories: utility companies, licensed tradespeople (plumber, electrician, HVAC), insurance agent, neighbors, poison control/non-emergency police, and property manager or HOA. Compile phone numbers, account numbers, and service addresses now — not during a 2 a.m. water leak. Print one copy for the fridge and save a digital version in your phone.

The first time your water heater floods the basement at midnight, you'll realize your phone contacts don't include your plumber's after-hours line or your water shut-off valve location. A proper emergency contact list solves both problems: it puts the right phone numbers in one place and reminds you where the critical shut-offs are before panic sets in.

Okoniq Property Hub stores your emergency contacts alongside maintenance logs and warranty documents, so everything lives in one searchable place when you need it fast.

What six categories belong on a home emergency contact list?

Every emergency contact list needs six core sections: utility companies with account numbers, licensed tradespeople with after-hours availability, your insurance agent and policy number, trusted neighbors who hold a spare key, municipal non-emergency lines, and any property manager or HOA contact. Each category solves a different type of crisis.

Start with utility companies — electric, gas, water, sewer, internet. Write down the customer service number, the outage hotline (often different), and your account number for each. When a tree knocks out power to your block, the electric company's outage line uses your account number to confirm your address and update repair timelines. If you can't find your account number, check a recent bill or log into the online portal now while the lights are on.

Next, list licensed tradespeople you've vetted or inherited from the previous owner. You need a plumber, an electrician, and an HVAC contractor at minimum. If your home has a septic system, add a septic service; if you have a well, add a well contractor. Write their normal business hours and their after-hours or emergency number if they offer one. A plumber who snakes clogged drains during business hours may not answer at 3 a.m., so confirm their availability when you add them to the list. If you're new to the area and don't have recommendations yet, ask your home inspector, your realtor, or your neighbors — then call those contractors to introduce yourself and ask if they offer emergency service.

Your insurance agent and policy number come next. Homeowners insurance covers sudden damage (burst pipes, tree through the roof) but not deferred maintenance; knowing your policy number speeds up the claims process when you call from a flooded living room. If your policy includes a 24/7 claims line, write that number separately — many insurers route emergency claims to a different team than routine policy questions. For more on what maintenance insurance does and doesn't cover, see how to diagnose a ceiling water stain and determine if it's a claim.

Add two or three trusted neighbors who know your schedule and can check on your house when you travel. Exchange phone numbers, confirm who has a spare key, and note any special arrangements (they feed your cat, you collect their mail). If something looks wrong while you're away — a broken window, water pooling in the driveway — a neighbor's call saves hours compared to waiting for a passerby to notice. If your home is part of an association, include your HOA manager or board president in this section, especially if they coordinate vendor access.

Include municipal non-emergency numbers: police non-emergency line, fire department non-emergency line, poison control (1-800-222-1222 nationwide in the US), and your local animal control if stray or injured animals are common in your area. These aren't 911-level emergencies, but they're urgent enough that you won't want to search for the number while it's happening. Animal control also handles bat removal if you discover wildlife in your attic.

Finally, if you rent out part of your property or manage the home through a service, add your property manager or HOA maintenance coordinator. They may have vendor relationships or on-call contractors you don't know about, and they need to be looped in if a tenant reports an emergency or a common-area pipe bursts.

Where should you store the contact list so you can find it during a crisis?

Print one copy and stick it on the inside of a kitchen cabinet door or the refrigerator where every household member knows to look. Save a second copy as a PDF in your phone's files app and email it to yourself so it syncs across devices. If you lose power and your phone dies, the printed copy on the fridge still works; if you're away from home when a tenant calls about a leak, the digital copy on your phone gets you the plumber's number in seconds.

Label the printed copy with your home's address and the location of critical shut-offs: main water valve (usually in the basement, crawlspace, or garage near where the water line enters), main electrical panel, gas meter shut-off, and furnace or boiler emergency switch. A guest or new tenant can follow those directions even if you're not home. If your water heater is prone to issues, note its location and age — a basement waterproofing contractor or plumber will ask those questions when you call about a leak.

Update the list every January and every time you hire a new contractor. Mark the update date at the top so you know the numbers are current. If a plumber retires or an electrician changes their after-hours policy, you'll catch it during your annual review rather than discovering the disconnected number during an emergency.

What details make an emergency contact actually useful?

Each contact needs more than a name and phone number to be useful at 2 a.m. Write the full business name, not just "Mike the plumber" — if Mike's voicemail says "Smith & Sons Plumbing," you want to know that when you're leaving a message. Include their license number if your state requires it (most do for electricians, plumbers, and HVAC contractors) so you can verify they're still licensed if years pass between calls.

Add service hours and after-hours fees if the contractor disclosed them. Some plumbers charge double rates after 10 p.m. or on weekends; knowing that upfront helps you decide whether to attempt a temporary fix yourself or pay the premium. If a contractor offers a service contract or annual maintenance plan (common for HVAC and septic), note your membership status and renewal date — members often get priority scheduling and discounted emergency rates.

For utility companies, write the outage map URL if they publish one. During a widespread power outage, the outage map shows estimated restoration times and how many customers are affected — information the phone line may not have. If you have a medical need that requires power (oxygen concentrator, refrigerated medication), register with your electric company's priority-restoration program and note your confirmation number on the contact list.

For neighbors, include the address as well as phone numbers — if you're directing a contractor to pick up a key or check on something, "the blue house two doors down" isn't precise enough. If a neighbor has a Ring doorbell or security camera that views your driveway, note that too; their footage may help if you need to file a police report or insurance claim.

How do you test the contact list before you actually need it?

Call each contractor once within 90 days of moving in to introduce yourself and confirm their current rates and availability. This isn't an emergency call — just say you're a new homeowner compiling a contact list and wanted to confirm they service your area and whether they offer after-hours dispatch. Most contractors appreciate the call; it flags you as an organized customer, and they'll remember your name when you do call with a real problem.

Schedule a non-urgent service call with your top-choice plumber, electrician, and HVAC contractor within the first year. Ask the plumber to inspect your shut-off valves and cast iron drain pipes if your home is older, ask the electrician to check your panel and aluminum wiring if applicable, and book the HVAC contractor for a furnace tune-up before winter. You're paying for preventive maintenance you need anyway, and you're also vetting their work quality, punctuality, and communication style before you're in a crisis.

Walk through the list with another household member or a trusted neighbor. Show them the printed copy, explain where the main water valve is, and confirm they can read your handwriting. If you travel frequently or own a rental property, text a photo of the contact list to your co-owner or tenant so they have it saved.

Should you include warranty and appliance model numbers with your contacts?

Yes — add a short equipment reference section at the bottom of the contact list with the make, model, and installation date of your water heater, furnace, AC condenser, and any major appliances still under warranty. When you call an HVAC contractor about a broken furnace, the first questions are "What's the make and model?" and "How old is it?" Having those answers written down saves 10 minutes of flashlight searching in the basement. Include the warranty expiration date if you have it; labor may be free if the unit is less than a year old.

If your home has specialized systems — a boiler with cast iron radiators, a heat pump with auxiliary strips, a septic system with an aerator — note the system type and any quirks the previous owner disclosed. A contractor who knows you have a 1960s boiler can bring different parts than if you'd said "radiator heat" with no context. For attic-related issues like ventilation imbalances or mold growth, note your attic's square footage and insulation type if you know it.

FAQ

How many plumbers or electricians should I keep on the list?

Two per trade is ideal — a primary and a backup. If your first-choice plumber is booked solid or out of town, you don't want to Google "emergency plumber near me" and pick blindly. The backup doesn't need to have done work for you yet, but they should have strong local reviews and confirmed availability in your area.

Do I need to list my mortgage company or property tax office?

Not on the emergency list — those are billing contacts, not crisis responders. Keep mortgage and tax information in a separate financial folder. The emergency list is only for people you might need to call with zero notice because something in your house broke or someone got hurt.

What if I don't have a regular HVAC contractor yet because I just moved in?

Start with your home inspector's recommendation or ask your realtor for the contractor most buyers in the area use. Call that contractor to introduce yourself and book a furnace or AC tune-up within 30 days — that visit gives you a known contact before the equipment actually fails. If the service feels overpriced or unprofessional, replace them on the list and try a different contractor next season.

Should I share my emergency contact list with my house sitter or pet sitter?

Yes. Email or text them a copy before they arrive, especially the sections on utility shut-offs and neighbors. If your house sitter smells gas or sees water pooling, they need the gas company's emergency number and your plumber's contact without having to call you first. Make sure they know where the printed copy is posted in the house as a backup.

How do I organize emergency contacts if I own multiple rental properties?

Create a separate contact list for each property with address-specific details — different utility account numbers, different local contractors if the properties are in different counties, and tenant emergency contact info. Save each list as "Emergency Contacts - 123 Main St.pdf" so you can pull up the right one instantly. If you manage multiple units, Okoniq Property Hub lets you attach a contact list to each property record so you never mix them up.
