You found someone who seems great. Before you hand over a key, you want to know they won't bring trouble with them. A roommate background check is how you find out: a tenant screening report the applicant authorizes, covering criminal records, eviction cases, and usually credit. A full report runs about $40 to $55 (as of October 2026), and many services let the applicant pay.
It's also less awkward than it sounds, as long as you do it in the right order. Here's what a report contains, which services work, the legal lines that matter when you're a tenant rather than a landlord, and the one thing no report can show you.
The Short Answer
Run a roommate background check through a tenant screening service that emails the applicant an invitation, such as TransUnion SmartMove, RentPrep, or MyRental. The applicant consents, usually entering their own Social Security number, and you get criminal, eviction, and credit results, often the same day. Don't use people-search websites for this: their own terms ban using results to decide who gets housing.
That answers "has this person had serious trouble before?" It says nothing about whether you'll get along, which is the part you'll live with every day. Both questions deserve an answer before anyone signs, and our full guide to screening a roommate covers the rest of the process.
What a Roommate Background Check Shows
A standard tenant screening report pulls four kinds of records.
- Criminal records. Convictions and some pending cases from county, state, and national databases, usually with sex offender registries. Federal law lets a report include convictions of any age, but arrest records and civil judgments generally drop off after seven years (15 U.S.C. 1681c). California's background report law cuts most criminal records off at seven years (Civil Code 1786.18).
- Eviction records. Court filings and judgments for possession or unpaid rent. As civil judgments, these generally age off after seven years too. In California, eviction cases stay sealed unless the landlord wins within 60 days, so many never appear at all (CCP 1161.2).
- Credit. Either a full credit report or a tenant score such as TransUnion's ResidentScore, which runs from 350 to 850 and is not a regular credit score (SmartMove FAQ). You'll see payment history, collections, and debts. You won't see income unless you buy an income add-on.
- Identity. A Social Security number check and address history, which confirms the person in front of you is the person on the report.
Reports get things wrong more often than you'd think
Public records are messy, and matching them to the right person is hard. The Consumer Financial Protection Bureau cited a study of 3.6 million eviction court records that found 22 percent of state eviction cases were ambiguous or false records (CFPB, November 2022). A common name, a dismissed case, or a stranger's debt can all land on the wrong report.
Treat a red mark as a question to ask, not a verdict.
Is It Legal to Run a Background Check on a Roommate?
Yes, with the person's permission and through a real screening service. Four rules matter.
Consent comes first. Under the federal Fair Credit Reporting Act, a screening company can release a report "in accordance with the written instructions of the consumer," and the law's limits on who may obtain one apply to "any individual," not only companies (15 U.S.C. 1681b). Get that permission in writing. An individual who pulls a report under false pretenses, or knowingly without a permitted reason, can owe actual damages or $1,000, whichever is greater, plus attorney fees (15 U.S.C. 1681n). Screening services build consent into the process: the applicant accepts your request, verifies their identity, and can decline. With SmartMove, you never see their Social Security number, and the soft inquiry doesn't touch their credit score (SmartMove renter FAQ).
People-search sites are off limits for this. TruthFinder, Instant Checkmate, Spokeo, and BeenVerified all ban tenant screening in their own terms. BeenVerified's terms say you may "NEVER" use the site for tenant screening (terms), and TruthFinder lists "housing or other accommodations" among its banned uses (terms). In 2023 the FTC hit TruthFinder and Instant Checkmate with a $5.8 million penalty, warning that "if you market your reports to be used to screen tenants or employees, you are a consumer reporting agency" (FTC, September 2023). Their results also come without the accuracy and dispute rights a real screening report carries.
Fair housing law mostly stays out of roommate choices, but not everywhere. In 2012 a federal appeals court held that the Fair Housing Act doesn't reach roommate selection, noting that "it's hard to imagine a relationship more intimate than that between roommates" (Fair Housing Council v. Roommate.com, 9th Cir.). That ruling covers the nine western states in its circuit. Federal criminal-record guidance has also pulled back: HUD withdrew its 2016 guidance on criminal records in housing, effective September 2025 (Federal Register). Local fair chance housing laws still matter, though, and they differ on roommates. New York City's law, in effect since January 2025, exempts a room rented by the occupant who lives there (NYC Commission on Human Rights). Cook County's exemption covers only owners renting rooms in their own homes (Cook County code), so a tenant filling a room there should check before rejecting anyone over an old record.
If the report changes your answer, say so. Federal law says that if "any person" takes adverse action based in whole or in part on a consumer report, they owe the applicant a notice (15 U.S.C. 1681m). The FTC lists what that notice includes: the screening company's name, address, and phone number, a statement that the company didn't make the decision, and the applicant's right to dispute errors and request a free copy of the report within 60 days (FTC, July 2023). The FTC writes that guidance for landlords, but the statute says "any person," so send the note.
Roommate Background Check Services Compared
These services are built and marketed for landlords. None of them says on its own pages whether a tenant filling a spare room can sign up, so read the terms as you create the account. Prices come from each provider's pricing page (as of October 2026).
MyRental asks requesters for their own Social Security number and a credit card to confirm they are real landlords (MyRental FAQ). Landlord platforms such as RentRedi and Avail also screen, but RentRedi needs a landlord subscription and Avail prices vary by location. Sources: SmartMove, RentPrep, MyRental, TurboTenant.
If you own the home and list the room on Zillow, its Rental Manager lets property owners who list rooms accept Zillow applications, which bundle a credit report and a background check (Zillow, February 2024).
How to Run a Roommate Background Check, Step by Step
Step 1: Write down your dealbreakers first
Before you meet anyone, decide what would actually rule someone out: an eviction judgment in the last three years, say, or rent still owed to a past landlord. Apply the same list to everyone. It's fairer, it's easier to explain, and it keeps you on solid ground where local fair housing rules reach further than federal law.
Step 2: Say it in your listing
Add one line: "Final candidates complete a standard tenant screening." Serious applicants expect it. People with something to hide, including plenty of scammers, quietly move on. Our guide to writing a roommate ad that filters well has more lines like it.
Step 3: Meet first, screen second
Run the report only on your final one or two people, after a real conversation and a reference call. Nobody should pay for a check that a 20-minute coffee would have made pointless. Bring questions that show how someone actually lives, and use this roommate screening checklist for the order of everything else.
Step 4: Send the invite through a screening service
Pick a service where the applicant enters their own details: you type in their name and email, and they get a link, verify their identity, and approve the report. You never handle their Social Security number, and you shouldn't ask for it by text or email.
Step 5: Read for patterns, not single lines
One old medical collection says little. Two eviction judgments in three years say a lot. Ask about anything that worries you before you decide, because reports carry errors.
Step 6: Tell them if the report changed your answer
If anything in the report played a part in a no, send a short email naming the screening company and its contact details, saying the company didn't make the decision, and noting the applicant can dispute errors and request a copy within 60 days. That's the notice federal law requires, and it gives someone with a mixed-up record the chance to fix it.
Step 7: Delete the report once you decide
You need it for one decision. After that, delete the PDF and any emails that carry it. A file full of someone's debts and court history is a liability sitting in your downloads folder.
Checks You Can Do Yourself in 15 Minutes
A few official sources cover a lot of ground before anyone pays for anything:
- Sex offender registries. The National Sex Offender Public Website searches every state, DC, the territories, and tribal registries at once. Its conditions of use warn that using results to harass someone can lead to prosecution.
- Court records. Search the court portal for the county or state where they recently lived, for eviction and small claims cases. Coverage varies; Wisconsin's Circuit Court Access is a good example of a statewide search.
- Their own credit reports. Anyone can download their reports from all three bureaus once a week at AnnualCreditReport.com. Ask them to pull theirs and walk through it with you.
- The landlord before the current one. A current landlord may praise a problem tenant just to get them out. The one before has no reason to.
- ID that matches. Check a government ID in person against the name on the application and the report.

What a Background Check Can't Tell You
A clean report means one thing: no serious trouble on record. It doesn't tell you whether someone does dishes the same day, has a partner over five nights a week, or thinks 1 a.m. is early. Those are the habits you'll live with every day, and a mismatch is expensive. This bad roommate cost calculator puts numbers on a mismatch.
Pair the record check with a fit check. Compare sleep schedules, guests, cleaning standards, noise, and how each of you handles shared money. A roommate compatibility quiz covers that in a few minutes, and this guide to roommate compatibility explains which mismatches matter most.
That's the half CoHabby works on. It doesn't run background checks; instead, profiles show stated habits like sleep, guests, and cleaning before you meet, so the first conversation can be about how you'd actually live together.
How to Ask Without Making It Weird
Most people take a screening request well when it sounds routine. Something like:
"Before anyone signs, I ask every final candidate to do the same standard screening through SmartMove. It covers credit, evictions, and criminal records. You'll get an email link, you verify your own identity, and I never see your Social Security number. I'm happy to show you my lease approval too."
Three things make it easier:
- Offer to go first. Showing your own lease approval or credit report turns a test into an exchange.
- Settle who pays up front. If the applicant pays, say so in the listing, not after the interview.
- Ask your landlord before you order anything. If the new roommate is joining the lease, the landlord will likely screen them anyway, and many leases require approval for any new occupant. Our guide to joint and individual leases explains who's on the hook for what, and a written roommate agreement covers the rest.
Frequently Asked Questions
Can I run a background check on a roommate without their permission
No legitimate screening service will run one without the applicant's consent and identity check. People-search sites skip consent, but their own terms ban using results for housing decisions, and the FTC has fined such sites for crossing that line.
How much does a roommate background check cost
A full report with credit, criminal, and eviction records costs about $40 to $55 (as of October 2026), and criminal-only checks start around $25. Many services let you choose whether the applicant pays.
Can I turn down a roommate because of a criminal record
Usually, if they would share your own home. A federal appeals court held in 2012 that the Fair Housing Act does not cover choosing a roommate, and New York City exempts a tenant renting a room in their own unit from its fair chance housing law. Some local exemptions cover only owners, so check your city and apply the same written criteria to everyone.
Does a roommate background check show income
Not by default. Income verification is usually an add-on, such as SmartMove's $49 Premium tier, or you can ask for recent pay stubs or an offer letter instead.
The Bottom Line
A roommate background check is cheap, fast, and normal, as long as the applicant consents and you use a real screening service. Decide your dealbreakers first, screen your finalists, ask about anything odd, and delete the report when you're done. Then spend just as much effort on the question no report answers: whether the two of you can actually share a kitchen.
