The Legal Foundation: Fair Housing Law
Tenant screening doesn't happen in a legal vacuum. The federal Fair Housing Act establishes seven protected classes that landlords may never use as a basis for refusing to rent, setting different terms, or otherwise treating applicants unequally: race, color, national origin, religion, sex, familial status, and disability. These protections apply at every stage — from how you word your rental listing to the final approval or denial decision.
Beyond federal law, most states and many cities extend protection to additional characteristics. Common additions include source of income (such as housing vouchers), marital status, sexual orientation, gender identity, and military status. Because the landscape varies significantly by location, landlords should confirm which protected classes apply in their jurisdiction before finalizing any screening policy. If you're new to rental ownership, the broader overview in Renting Out Your Home for the First Time covers these legal basics alongside pricing and lease fundamentals.
Local Law May Be More Restrictive
Federal fair housing law sets a baseline, but state and city rules can — and often do — go further. For example, some jurisdictions prohibit asking about criminal history until after a conditional offer has been made (so-called "ban the box" rules), and others bar landlords from refusing applicants who pay with Section 8 housing vouchers. Always verify the specific rules that apply in your city and state before finalizing your screening policy.
Criteria Landlords Can Legally Consider
Within the boundaries set by fair housing law, landlords have meaningful flexibility to set objective, financially grounded standards. Permissible screening factors include:
- Credit history: Payment patterns, outstanding debt, and prior collections or evictions reported on a consumer credit report are all fair game. Define your minimum credit threshold in writing before you start reviewing applications.
- Income and employment verification: Requiring proof that an applicant earns enough to comfortably cover rent — commonly 2.5 to 3 times the monthly rent — is an accepted and legally sound practice when applied consistently.
- Rental history: Prior landlord references, evidence of on-time payment, and records of lease violations or evictions are relevant indicators of future behavior.
- Criminal background: Landlords may consider criminal history, but the policy must be narrowly tailored. HUD guidance warns against blanket bans that exclude anyone with any conviction, because such policies can produce a disparate impact on protected racial groups. A defensible approach focuses on specific offense categories directly relevant to tenancy safety, the severity of the offense, and how much time has elapsed.

Protected classes under the federal Fair Housing Act
Race, color, national origin, religion, sex, familial status, and disability are the seven federally protected characteristics in housing under 42 U.S.C. § 3604.

States with protected classes beyond federal minimums
Many U.S. states have enacted additional fair housing protections covering characteristics such as source of income, sexual orientation, and marital status, according to the National Fair Housing Alliance.
2.5x–3x
Common income-to-rent ratio benchmark
A monthly gross income requirement of 2.5 to 3 times the rent is a widely used industry standard among landlords and property managers across the U.S.
Consistency is the cornerstone of legal compliance. Whatever standards you set, apply them identically to every applicant who reaches that stage of your process.
What Landlords Cannot Do
Even when a landlord believes a decision is purely financial or practical, certain actions cross a legal line:
- Steering or discouraging applicants: Telling a prospective tenant a unit is unavailable when it isn't, or discouraging inquiries based on a protected characteristic, violates the Fair Housing Act even if no formal application is ever submitted.
- Different terms for different groups: Requiring a larger security deposit, imposing stricter lease conditions, or offering a shorter lease term to an applicant because of a protected characteristic is illegal — even if the unit is ultimately rented to them.
- Refusing reasonable disability accommodations: Landlords must make reasonable accommodations for applicants with disabilities. This includes allowing a service or emotional support animal in a no-pets building when properly documented, and may extend to modifying application processes.
- Asking prohibited questions: Questions about national origin, religion, pregnancy, or whether an applicant has children have no place in the screening process.
It's also worth noting that the Fair Credit Reporting Act (FCRA) imposes separate obligations. If you use a consumer report to take an adverse action — including rejecting an applicant — you must provide the applicant with a written adverse action notice identifying the reporting agency.
Building a Defensible Screening Process
The most effective protection against a fair housing complaint is a documented, written screening policy applied uniformly before the first application is reviewed. A sound process typically includes:
- Written criteria established in advance: Define minimum income, credit, and rental history requirements on paper. These criteria should be business-justified and applied without exception.
- A consistent application form: Every applicant should complete the same form. Collecting different information from different applicants opens the door to claims of unequal treatment.
- Objective, documented decisions: Record the specific reason for each approval or denial, tied to your written criteria. If you ever face a complaint, this paper trail is your primary defense.
- First-qualified, first-considered approach: Processing applications in the order they are received and offering the unit to the first applicant who meets your criteria reduces discretion and exposure.
Keep Your Screening Criteria in Writing
Draft your minimum income, credit, and rental history requirements before you list the property — not after you've started reviewing applications. A written policy created in advance signals objectivity and gives you a clear record to point to if your decision is ever questioned. Store all application materials and denial reasons in a secure file for at least two to three years.
Pair a sound screening process with other landlord fundamentals — such as choosing the right lease structure, covered in Month-to-Month vs. Fixed-Term Leases, and pricing rent competitively as discussed in Setting Rent That Attracts Reliable Tenants — to build a rental operation on solid legal and financial footing.

Frequently Asked Questions
Yes, credit score is a legally permissible screening criterion as long as the same standard is applied to every applicant. Landlords should define the minimum acceptable score in writing before reviewing applications so the standard is objective and consistent.
In most states it is legal to consider criminal history, but blanket bans on anyone with any record can violate HUD guidance if they have a disparate impact on protected classes. Policies should focus on specific offense types and how recently they occurred, and some cities and states restrict when in the process you may ask.
No. Familial status — which includes households with children under 18 — is a protected class under the Fair Housing Act. Refusing to rent to families with children or imposing different terms because of them is illegal. Limited exceptions exist for qualifying senior housing communities.
There is no federal cap on income requirements, and a 2.5x–3x monthly income-to-rent ratio is a common industry benchmark. The ratio must be applied uniformly to all applicants. Some localities limit or regulate income verification requirements, so check local rules.
If you pull a credit report and it influences a rejection, the Fair Credit Reporting Act requires you to send an adverse action notice that includes the name of the reporting agency used. Beyond that, federal law does not generally require landlords to explain every rejection, though good documentation practices are advisable.
Generally yes, landlords may prohibit pets. However, they cannot deny housing to an applicant with a disability who requires a service animal or an emotional support animal as a reasonable accommodation — these are not legally treated as pets under fair housing law.
