Tenant Screening in San Francisco: Legal Limits, Smart Process, and Avoiding Costly Mistakes
How to screen tenants in San Francisco without breaking the law — what you can ask, what you can't, what to actually verify, and how to protect yourself from costly placement mistakes.
Why tenant screening in SF is different
I'm Christopher Lee, a San Francisco Realtor and broker who works with rental property owners across the city. If you own rentals in SF, the single biggest risk to your investment is who you let in the door — and screening in San Francisco is a legal minefield that traps DIY landlords every month.
SF has stricter tenant-protection rules than almost any city in America. Get screening wrong and you face Fair Housing complaints, civil penalties, and — worst of all — a tenant you can't easily remove who's locked in at a rent that won't track market for years. (See SF Rent Control Explained for why that matters.)
Done right, screening protects your asset for a decade. Done wrong, it sinks the investment.
The legal framework, in plain English
You must comply with:
- Federal Fair Housing Act: no discrimination based on race, color, national origin, religion, sex, familial status, or disability.
- California FEHA: adds source of income, ancestry, gender identity, sexual orientation, marital status, medical condition, military/veteran status, and more.
- San Francisco Police Code Article 49 / "Fair Chance Ordinance": limits criminal-background inquiries. You generally can't ask about criminal history until after a conditional offer.
- SF Source of Income protections: you cannot reject an applicant because they use Section 8 or other rental assistance.
Violations are expensive. Settlements routinely run $10K–$50K, and the damage to your time and stress is bigger than the dollars.
What you CAN screen on
- Income: typically 2.5x–3x monthly rent, verified with pay stubs, tax returns, offer letters, or bank statements.
- Employment: verify with HR directly when possible.
- Credit: FICO via a screening service. Most landlords look for ~680+ in SF, but use a holistic view.
- Rental history: prior landlord references — past behavior is your best predictor.
- Eviction history: court records, with care around timing and Fair Chance considerations.
- Identity verification.
What you CAN'T do
- Ask about family status, plans for children, or marital arrangements.
- Reject applicants for using housing vouchers.
- Run criminal background checks before extending a conditional offer (Fair Chance Ordinance).
- Apply different income thresholds to different applicants for the same unit.
- "Steer" applicants toward or away from specific units.
- Use minimum credit score in a rigid way that has disparate impact.
The screening process I recommend
| Step | Action | Notes |
|---|---|---|
| 1 | Written rental criteria, disclosed upfront | Same rules for every applicant |
| 2 | Standard application (use a current CA form) | Collect signed authorization for credit/background |
| 3 | Pre-screen for income and basic fit | Don't waste applicants' time or yours |
| 4 | Show the unit to anyone who meets threshold | Document every interaction |
| 5 | Full screening via reputable service | TransUnion SmartMove, Experian Connect, etc. |
| 6 | Verify employment + landlord references | Phone, not just email |
| 7 | Make conditional offer | Now you can ask criminal questions if needed |
| 8 | Execute SF-compliant lease | Include all required addenda |
Verifying income — and the traps
- W-2 employees: pay stubs (last 2 months) + employer verification.
- Self-employed: last 2 years of returns + recent bank statements.
- Tech workers with RSUs: average vesting + base. Don't disqualify a strong applicant because RSUs aren't on a W-2. (Similar logic to what I describe in Buying with RSUs.)
- Fixed income (Social Security, pension, disability): treat the same as wages. Discriminating against these income sources is illegal.
- Vouchers (Section 8): voucher amount counts toward the income threshold.
Landlord reference calls — the single highest-ROI step
Most landlords skim references. I treat them like a deposition. Sample questions for prior landlord:
- What dates did they rent from you?
- Did they pay on time, every month?
- Were there ever complaints from neighbors?
- Was the unit returned in good condition?
- Did they give proper notice?
- Would you rent to them again? (The most diagnostic single question.)
Always call the landlord two before current, not just the most recent. Current landlords sometimes give glowing reviews to get a problem tenant out.
What to do with the results
Build a written, consistent decision framework:
- Income < 2.5x rent → decline (applied evenly).
- Recent eviction within X years → decline (with Fair Chance caveats).
- Major derogatory credit + thin rental history → decline.
- Strong rental history + slightly low credit → consider with co-signer or additional deposit (note: SF caps security deposits — 2x for unfurnished, 3x for furnished as of writing; check current law).
Document why every applicant was approved or declined. If you ever face a Fair Housing complaint, that paper trail is your defense.
When to hire it out
If you own 1–2 units and have a day job, screening eats weekends and exposes you to legal risk. Many SF owners net more after fees by using a professional property manager precisely because of better tenant selection. See How to Hire a Property Manager and the Rent Estimate Guide.
The cost of getting it wrong
A bad tenant in a rent-controlled SF unit can cost:
- 6–18 months of below-market rent.
- $20K–$80K to legally remove (attorney fees, lost rent, possible buyout).
- Permanent reduction in unit value if rent stays artificially low for years.
A weekend of careful screening prevents almost all of that.
