Open House Guidelines for 2026: What to Do, What to Avoid and What to Check

Updated October 2026. Open house guidelines for visitors, whether you’re buying or renting: how to behave, what to check in 20 minutes and what to ask. Health and moisture figures are from the EPA; market figures from NAR.

At an open house, greet the host, sign in, ask before taking photos, keep pets and kids close, and spend your time on the things photos hide: water stains, musty smells, floors, noise and storage. As of October 2026, the EPA’s mold guide says to keep indoor humidity below 60%, so a damp basement is worth a closer look. Then ask about the home’s history.

What should you do at an open house?

Greet the host and sign in

Say hello, give your name and sign the book. If you have an agent, introduce them or mention them, so the host knows. Hosts use the sign-in sheet for safety and follow-up, not to pester you.

Ask before taking photos or video

Many sellers are fine with it, some aren’t. Ask first, and keep other visitors out of the frame.

Take notes

After three homes in an afternoon, they blur together. Jot the address, what you liked and what worried you. A quick voice memo in the driveway works too.

Wear easy shoes

Some hosts ask you to remove shoes or wear covers. Slip-ons save time, and you’ll be on stairs, in the yard and maybe in an attic.

Open closed doors

Closets, pantries and the garage are fair to look at. If a door is locked, ask. No part of a home for sale should be off-limits.

Talk to neighbors on the way out

Neighbors know about traffic, noise, flooding and parking. Ask after you’ve formed your own view of the house.

What should you avoid at an open house?

Don’t criticize the home out loud. The owner may be nearby, and you never know why they’re moving. Save your notes for the car.

Don’t share too much. Your budget, your deadline and how much you love the place are negotiating information. Keep small talk light.

Don’t bring pets. Even calm pets can upset the host’s animals or other visitors with allergies.

Don’t let kids roam. Keep children with you. Pools, stairs and tools in garages are real hazards in a home you don’t know.

Don’t dig through drawers or personal items. Look at the space, not the owner’s belongings. Opening a closet is fine; going through what’s in it isn’t.

Don’t judge by the furniture. Picture the rooms empty. Bad decor is cheap to fix; a bad layout isn’t.

What should you check during an open house?

You have maybe 20 minutes. Spend them on things a listing photo can’t show.

• Moisture: stains on ceilings, soft spots near tubs, condensation on windows and a musty smell. The EPA links mold to moisture and says spots over about 10 square feet call for professional cleanup.
• Water pressure: run a sink and shower, then flush a toilet.
• Drainage: gutters and downspouts should send water away from the house, and the ground should slope away too.
• Floors: look for slopes, cracks and gaps under doors. Lift a corner of a rug if the host allows it.
• Noise: close the windows and listen for traffic, trains or neighbors.
• Light: note which rooms get sun and when.
• Storage: closets, attic, basement and garage space for what you own.
• Systems: the age of the roof, water heater and HVAC unit, often on a label. Our list of common AC problems you shouldn’t ignore helps you spot trouble.
• The yard and garage: fences, sheds, trees near the roof and space for a car.

Square footage matters more than many visitors think. If the rooms feel smaller than the listing says, ask how it was measured. Some states have specific rules; see our explainer on North Carolina square footage verification for one example.

Planning to rent instead? The same checks apply. Look closely at storage and appliances, and see our ideas on rental property appeal and smart storage.

What questions should you ask the host?

Hosts can’t always answer everything, but these are fair to ask:

• How long has the home been on the market, and have there been price changes?
• Are there offers already, and is there an offer deadline?
• How old are the roof, water heater and HVAC system?
• Has the home had water damage, and was it repaired with permits?
• Has it been tested for radon? The EPA calls radon the second leading cause of lung cancer.
• What are the property taxes, utilities and any HOA dues?
• Can I see the seller’s disclosure form?

Write the answers down, and check them later against the disclosures and the inspection.

What should you do after the open house?

Go back at a different hour. Rush-hour traffic, a weekend party house next door or a dark living room in the afternoon won’t show up on a Sunday at noon. Our guide on visiting a home at different times explains what to look for. For more on making each visit count, read tips for a successful home tour.

If you like the home, line up financing before you offer. With a median of 33 days on market in September 2026, many homes give you time for a second visit, but well-priced ones can go fast.

Buyers can save on the agent side too. Beycome’s program for buyers is open to every buyer on homes listed by other agents. There’s no upfront fee; Beycome keeps 1% of the price (minimum $1,499) and credits the rest of the buyer-agent commission at closing, with lender approval. The credit can’t apply where no buyer-agent commission is offered, like most FSBO homes, or on homes listed by Beycome sellers. Renters can search rentals on Beycome as well.

Hosting your own open house?

If you’re the seller, print the free signs below, set out a sign-in book, lock away valuables and medications, and ask visitors to follow the same guidelines. Our guides to running an open house, scheduling a FSBO open house and the Sunday open house cover the rest.
