Is the "income must be 3 times the rent" rule legal, and how should you apply it?
Yes, in general a landlord may set a minimum income, such as three times the monthly rent, if it is written down and applied the same way to every applicant. The limits come from source of income laws: California and Washington, for example, require you to measure a voucher holder against only the part of the rent they pay. How you count income, and what you accept in its place, matters as much as the multiple itself.
Why owners use an income multiple
An income test is a quick way to judge whether rent will be affordable for the household. Three times the rent means rent takes about a third of gross income. Some owners use 2.5 or 2.75 to widen the pool. There is no federal number; the multiple is your business choice. What the law cares about is that it is the same for everyone and does not screen out a protected group in a way you cannot justify.
Example a made-up two-bedroom rents for $1,600. At three times rent the household needs $4,800 a month in gross income, or $57,600 a year. At 2.5 times it needs $4,000 a month, or $48,000 a year. Dropping the multiple by half a point opens the unit to households earning $9,600 a year less.
Voucher holders: test only their share of the rent
Some states protect source of income and spell out how income tests apply. Washington says any rent voucher or subsidy must be subtracted from the monthly rent before you check whether your income criteria are met (RCW 59.18.255). California's Civil Rights Department says a provider may consider only the tenant's portion of the rent, and that any income standard not based solely on that portion is unlawful (CRD source of income FAQ). New York lists lawful source of income among the protected bases in its Human Rights Law (Executive Law 296).
Example a made-up $1,600 unit, three times rent policy, and an applicant with a voucher whose share is $400 a month while the housing authority pays $1,200. In Washington or California, the test is three times $400, so the applicant needs $1,200 a month of income, not $4,800.
The full picture on vouchers, including which states protect them, is in source of income laws and housing vouchers.
What counts as income
Most disputes are not about the multiple but about what you counted. Write the answers down before you advertise.
| Question | A clear written answer |
|---|---|
| Gross or take-home pay? | Gross monthly income, before taxes |
| Which sources count? | Every lawful source: wages, self-employment, Social Security, disability benefits, pensions, child support, alimony, assistance |
| Roommates? | Add the incomes of every adult on the lease |
| Proof? | Two recent pay stubs, an offer letter, a benefits letter, or the last tax return for self-employed people |
| Variable income? | Average the last 12 months |
| No income, but savings? | Accept liquid savings equal to, say, 12 months of rent, as an alternative |
Counting every lawful source is the safe default. If your form counts wages but not disability or retirement benefits, a test that looks neutral can fall hardest on people with disabilities or older applicants, both groups the law protects in many places.
Applying it without surprises
- Put the multiple and the list of accepted income in your written screening criteria.
- Give the criteria to applicants before they pay any fee.
- Compute it the same way every time, ideally in one spreadsheet or tool.
- Offer the same alternatives to everyone who falls short: a guarantor, a larger deposit where your state allows it, or proof of savings.
- Record the calculation in the file, so you can show why each decision was made.
If a consumer report played any part in asking for a guarantor or more deposit, an adverse action notice is required; see co-signers and guarantors and the screening checklist.
Example a made-up couple applies for the $1,600 unit. One earns $2,900 a month in wages and the other receives $1,300 a month in disability benefits. Combined gross income is $4,200. At three times rent they need $4,800, so they fall $600 short. Under the owner's written policy anyone who falls short may add a guarantor who earns five times the rent, or show savings of $19,200 (12 months of rent). They choose the savings route and are approved.

Questions
- Can a landlord require 3 times the rent in income?
- Generally yes, if the rule is written and applied the same way to everyone. In states such as California and Washington, voucher holders are measured against only their share of the rent.
- Is the income requirement based on gross or net income?
- Whichever you choose, but write it down. Most owners use gross monthly income because it is easy to verify from pay stubs and benefit letters.
- Do roommates combine income to qualify?
- They can if your written policy says so. Adding the incomes of every adult on the lease is common and easy to explain.
