Tenant screening is one of the most important things you do as a landlord. It's also one of the most legally complicated, and that's especially true in California.
The state has layered a significant amount of regulation around the screening process, from how much you can charge for an application to what information you're actually allowed to use when making a decision. Get it right, and you protect your investment with a qualified, reliable tenant. Get it wrong, and you're looking at fair housing complaints, fines, or worse.
Here's a breakdown of what California law requires and what it prohibits, so you can approach the screening process with confidence.
Key Takeaways
California caps tenant screening fees at $65.86 per applicant and requires itemized documentation of how the fee was used.
Landlords cannot reject applicants based on source of income, including Housing Choice Voucher holders: informal policies that functionally exclude them can still constitute a violation.
All screening criteria must be established in writing before applications open and applied consistently to every applicant without exception.
Criminal history policies must be individualized. Blanket denial policies based on felony history carry significant legal risk in California.
Written denial notices are required by law, including disclosure of any credit reporting agency used in the decision.
What California Law Says About Application Fees
Before you even look at a single application, there's a cap on what you can charge. Under California Civil Code Section 1950.6, landlords are limited to charging a screening fee that reflects the actual cost of obtaining a credit or background report. As of 2026, that cap is set at $65.86 per applicant and is adjusted annually for inflation.
That fee must be itemized and provided to the applicant in writing, and if you don't actually pull a report — say, the unit gets rented before you process the application — you're required to refund the fee or provide a copy of the report to the applicant.
This seems straightforward, but many self-managing landlords run into trouble here by charging a flat fee without documentation or forgetting to issue refunds when circumstances change.
Source of Income Protections
California prohibits landlords from discriminating against applicants based on their source of income. That includes Section 8 / Housing Choice Voucher recipients. You can't reject an applicant solely because they're receiving housing assistance, and you can't impose different terms, conditions, or standards on them compared to other applicants.
This is an area where landlords frequently run afoul of fair housing law without intending to. Stating "no Section 8" in a listing, even informally, can constitute a violation. The same applies to policies that functionally screen out voucher holders, such as requiring income multiples that voucher recipients can't meet by design.
If a voucher applicant meets your published criteria, they need to be evaluated the same way as any other applicant.
What You Can and Can't Use to Screen
California's fair housing laws prohibit using any protected class characteristics as a basis for denial. That includes race, color, religion, sex, national origin, familial status, disability, marital status, sexual orientation, gender identity, and several other protected categories under state and local law.
Criminal history is a particularly sensitive area. There's no blanket rule that says you can or can't use it, but California law and HUD guidance both require that any criminal history policy be individualized and consider the nature of the offense, how long ago it occurred, and whether it's actually relevant to tenancy. Blanket "no felonies" policies are legally risky.
Consistent, objective criteria applied equally to every applicant is the standard you need to meet. That means establishing your screening criteria in writing before applications open (things like minimum FICO score, income-to-rent ratio, rental history requirements, and acceptable eviction history) and applying them the same way every time.

Income Verification and the Fraud Problem
Income verification sounds simple. In practice, it's one of the biggest vulnerabilities in the screening process. A significant percentage of rental applications contain false or exaggerated information: fake pay stubs, fabricated landlord references, and, in some cases, outright identity fraud.
Cross-referencing multiple documents (pay stubs, bank statements, offer letters) and contacting previous landlords directly, rather than relying only on contact information the applicant provides, can catch many of these inconsistencies before you're locked into a lease.
That said, the verification process also has to stay within legal bounds. You can require documentation of income, but how you obtain and use that information matters, particularly for applicants who receive government assistance.
The Cost of Getting It Wrong
A bad screening decision can go in two directions. Place the wrong tenant, and you're potentially looking at unpaid rent, property damage, and the time and expense of an eviction, which in California can easily run several months and thousands of dollars. Make a discriminatory screening decision, even unintentionally, and you face fair housing complaints, investigations, and significant fines.
Neither outcome is acceptable, which is why the process matters as much as the outcome. Screening isn't just about finding a good tenant; it's about documenting a fair, legal, consistent process that holds up to scrutiny.
FAQ
Can I require tenants to earn three times the monthly rent in California?
Income requirements are common and generally permitted, but they have to be applied uniformly and can't be used in a way that has a disparate impact on a protected class. For voucher holders, income ratios must account for the portion of rent covered by the voucher, not the full rent amount. Otherwise, the standard effectively excludes them, in violation of source-of-income protections.
Can I run a credit check on every applicant?
Sometimes, and only with their written consent and within the application fee limits described above. Keep in mind that California law limits whether or not you can use credit information for applicants who receive certain forms of public assistance.
What happens if I accidentally violate fair housing law during screening?
Intent doesn't determine liability in fair housing cases. If a policy or practice has a discriminatory effect, even if unintentional, it can still result in a complaint or investigation. The safest approach is to have written criteria established before you begin accepting applications and apply them consistently.
Do I need to give every applicant a reason for denial?
Yes. California requires landlords to provide written notice of denial and disclose whether a credit report was used. If adverse action was taken based on a report, the applicant has the right to know which reporting agency was used.
What About DIY Screening
California's screening laws are detailed, frequently updated, and unforgiving of honest mistakes. Most self-managing landlords understand the basics (verify income, check credit, call references), but the specifics around source-of-income protections, criminal-history policies, application-fee rules, and denial notices are where things get complicated fast.
Partnering with a property manager who has a documented, legally compliant screening process built around California law is one of the most straightforward ways to protect your investment and stay on the right side of fair housing.
