What Can a Landlord Legally Ask a Tenant Applicant?

The rule is simple to state and easy to forget in practice: ask about the applicant's ability to pay and rent responsibly, never about traits that are protected under fair housing law. The Fair Housing Act protects applicants based on race, color, religion, national origin, sex, disability, and familial status, and Pennsylvania law adds protections such as ancestry and age. Philadelphia adds sexual orientation, gender identity, marital status, and source of income, which includes housing vouchers.

That means you may not ask whether an applicant is married or has children, what religion they practice, where their family is from, or whether they have a disability. Questions about these traits do not merely risk liability; they signal that your decision might be influenced by bias, which damages your defense even when you ultimately approve the applicant.

The safe path is to standardize: one application, the same questions, in the same order, for every applicant. Consistency is both a legal defense and a screening discipline.

The questions that are safe to ask are the ones that predict whether rent will be paid and the home will be respected. You can request identification, current and previous addresses, employment and income information such as pay stubs or an employer contact, and landlord references for current and past rentals. You can ask for written consent to run a credit check and a background check through a tenant screening service, and you can ask about eviction history.

You may also establish objective criteria in advance, such as a minimum household income, usually expressed as a multiple of the rent, or a requirement of no recent evictions. Applying the same criteria to every applicant is what keeps those standards lawful. Document the criteria and the reasons for every denial, because fair housing agencies may ask you to explain them.

Pennsylvania and Philadelphia both emphasize source-of-income protections, so you cannot simply refuse an applicant because their income comes from a voucher, Social Security, or child support. Judge the applicant on their ability to meet the lease terms, not on where the money comes from.

The Application Form Itself

Design the application form around the same discipline: fields for identity, current and prior addresses, employment and income, landlord references, and consent for screening. No question on the form should have a protected-class answer hiding in it, and the form should be identical for every applicant, with a version number and a date so you can prove which form governed each application. A clean, consistent form makes the fair housing discussion simple: the same people, the same questions, the same criteria.

Some questions are legal but loaded, and how you ask them can change the answer from lawful to unlawful. Criminal background checks are allowed, but federal guidance urges landlords to consider the nature, severity, and recency of a conviction rather than applying a blanket ban that disproportionately excludes certain groups. If you use criminal history, apply a consistent, documented standard.

Occupancy questions need care. You can limit the number of occupants for health and safety reasons, and most housing codes set occupancy standards, but you cannot set rules that discriminate against families with children. A policy like no more than one person per bedroom is generally acceptable only if it is applied consistently and based on real capacity limits.

Credit history is fine to consider, but be careful asking applicants to take a specific action as a condition, such as requiring a cosigner only from applicants in a protected group. Set the cosigner policy in advance and apply it uniformly based on credit and income criteria.

Criminal and credit reports come with their own legal rules, and the Fair Credit Reporting Act governs how you use them. Before you run any consumer report, get the applicant's written consent, clearly stating what you will pull and who will see it. Use a screening service designed for tenant screening so the reports are accurate and compliant.

If you take an adverse action, such as denying the application or changing the terms because of something in a report, you must provide the applicant an adverse action notice that explains their right to see the report and dispute errors. Skipping this step is a common and costly mistake.

Finally, never ask for documents that are not relevant to the tenancy. Social media passwords, medical records, and bank balances beyond what is needed to verify rent-paying ability invite trouble and have no place in a residential application.
