Open House QR Code: Listing Details, Sign-In and Save Contact in One Scan
October 27, 2026 · 7 min read
How to make an open house QR code that opens sign-in, listing details and a Save contact button, with print sizes, sign-in options and ad rules to check.
Quick answer: An open house QR code should open one page that holds the sign-in form, the listing details and a Save contact button for you. Build that page first, put "Sign in" and the listing at the top, then print the page's QR code on your flyer, yard sign rider and sign-in table card. Scan it with two phones before you print a batch.
What should an open house QR code open?
One page, not five separate codes. Visitors at an open house have a phone in one hand and a feature sheet in the other. Give them a single scan that answers everything they might want, in this order:
- Sign in. The link to your sign-in form, first on the page, labelled plainly: "Sign in for this open house."
- Listing details. The full listing on your brokerage site or IDX search: photos, price, square footage, taxes, HOA fees.
- Disclosures and documents. The seller's disclosure, HOA documents or floor plan, but only what the seller and listing broker have agreed you can share. Host the files on your brokerage site or a shared drive and link to them. The lit.bio free plan does not host files.
- Mortgage pre-approval. A link to a lender, or two, for buyers who are not pre-approved yet. More on the rules for this below.
- Save contact. A button that drops your name, number, email, brokerage and headshot into the visitor's phone contacts in one tap.
- Your other listings and reviews. For the visitor who likes the area but not this house.
That is six items, which fits inside the free plan's 10 links with room to spare. Your Instagram, Facebook and phone number go in the social icon row, which does not count toward the limit.
How do I set up an open house QR code sign-in?
- Create your sign-in form (options below) and copy its link.
- Make a free page at lit.bio/yourname, or use the page you already have in your Instagram bio.
- Add the sign-in link and move it to the top. Add the listing link second.
- Fill in the contact card: name as licensed, title, brokerage, phone, email, website and office address. A Save contact button appears on your page.
- Download the page's QR code and add it to your flyer and sign designs.
- After the open house, replace the top two links with your next listing. The printed code keeps working because it points to your page, not to one property.

Which open house sign-in option should I use?
The QR code gets people to the form. The form itself can come from several places. Checked October 2026:
| Sign-in option | What it does | Cost (as of October 2026) | Watch out for |
|---|---|---|---|
| Paper sign-in sheet | Visitors write their name and number | Free | Illegible handwriting, and every visitor can read the names above theirs |
| Google Forms | A form you build; answers land in a Google Sheet | Free with a Google account | Forms has no built-in QR button, so link it from your page or use a QR generator |
| Curb Hero | Open house app with QR or on-screen sign-in and CRM sync | Free to download on the App Store | Check which features your plan includes in the app |
| Lone Wolf Spacio | Sign-in on iPad, iPhone or Android, with CRM integration and follow-up emails | Priced on the Lone Wolf site; teams book a demo | A paid tool; branded forms carry a setup fee |
| Your brokerage CRM | Many CRMs include an open house or event form | Often included in what you already pay | Ask your broker before adding a separate app |
| lit.bio email capture | Collects email addresses on your page itself | Pro, $9 a month or $49 once | Email only, and no CRM sync |
For most solo agents, a Google Form or a free open house app linked at the top of the page is enough. Whatever you use, say on the form how you will use the details. If you plan to call or text visitors with marketing, ask for that consent clearly on the form and check the rules with your broker.
Where should the QR code go, and how big should it be?
A common rule of thumb is about one inch of code width for every 10 inches of scanning distance. Size each placement for the way people actually stand when they see it:
| Placement | Typical scan distance | Minimum code size | Call to action |
|---|---|---|---|
| Flyer or feature sheet | In hand, under 12 inches | 1 to 1.5 inches (2.5 to 4 cm) | "Scan for photos, disclosures and my contact" |
| Yard sign rider | Sidewalk, about 5 feet | 6 inches or more | "Open house Sat 1 to 4. Scan for details" |
| Sign-in table card | Standing at the table, 2 to 3 feet | 3 to 4 inches | "Scan to sign in" |
| Front door or entry easel | 3 to 4 feet | 4 to 5 inches | "Sign in here before your tour" |
Nobody scans a yard sign from a moving car, so put the code where people stop: the rider below the sign, the entry and the kitchen counter.
How do I make sure the QR code scans?
- Contrast. Dark squares on a light background. Black on white is safest. Pale brand colors and inverted codes fail more often.
- Margin. Leave a clear border of at least four of the code's small squares on every side.
- Glare. Use matte stock or a matte laminate for signs. Gloss reflects sunlight straight into the camera.
- Test the proof. Print one copy at real size and scan it with an iPhone and an Android phone, outdoors in daylight and indoors in a dim hallway.
- Print the address too. Add lit.bio/yourname in small text under the code for anyone whose camera will not cooperate.
- Avoid trial QR generators. Some "dynamic" codes stop working when a trial or plan ends. Our guide to QR code business cards explains why, and how to make a QR code for your link in bio covers the download step.
What advertising rules apply to open house flyers and QR pages?
This is general guidance for US agents, not legal advice. Rules vary by state and by brokerage, so confirm with your managing broker and your state real estate commission before you print.
- Brokerage name. NAR's Code of Ethics, Standard of Practice 12-5, says REALTORS® must disclose their firm's name in a reasonable and readily apparent manner in advertising in any medium. Put it on the flyer and in your page bio, not only behind a link. State rules can be stricter: Texas wants the broker's name at least half the size of the largest agent contact information, and Florida wants the licensed firm name next to the contact details in online ads.
- License details. Some states also want a license number, license type or office address in ads. Your commission's advertising page will say.
- Fair housing. The Fair Housing Act's advertising rule (24 CFR 100.75) bars ads that indicate a preference or limitation based on race, color, religion, sex, disability, familial status or national origin, and NAR's Standard of Practice 10-3 adds sexual orientation and gender identity for members. Describe the home, not the people you picture living in it. Many brokerages also require the Equal Housing Opportunity logo or slogan on flyers.
- Permission to advertise. Only promote a listing you have the listing broker's permission to advertise, and only share disclosures the seller has agreed to share.
- Lender links. Do not take a fee or anything of value for featuring a lender. RESPA Section 8 prohibits payments for referrals of settlement business, and the CFPB has treated some co-marketing deals as violations. Linking more than one lender keeps the choice with the buyer.
- A true picture. NAR's Article 12 asks for honest advertising. Remove the listing from the top of your page once it is under contract or sold.
What should the page do after the open house?
Check your page analytics (7 days on the free plan, 90 days on Pro) to see how many visits the weekend brought and which links got tapped. If nobody opened the disclosures, move them lower. Then swap in your next listing. Visitors who tapped Save contact still have you in their phone, which matters in a business where a casual visitor may buy in two years.
The page, the QR code and the Save contact button are free. Make your open house page and print one code that works for every listing you hold.
