Tenant Lead Routing and Fair Housing for Single-Family Operators

A routing rule decides who answers a rental inquiry, how fast, and what that person is allowed to say. Each of those three choices can produce differences in treatment between applicants, and the Fair Housing Act and HUD's regulations reach differences in treatment at the inquiry stage, before any application exists.¹² The safest design is one that gives every inquiry the same information, the same criteria and the same timing, and records that it did.

HUD withdrew its April 2024 guidance on advertising through digital platforms in 2025, but the statute and the regulations it interpreted were not withdrawn.³⁴ Related pages: fair housing protected classes by state, tenant screening rules, rental fee laws, TCPA texting rules, the tenant lead to lease playbook and the scripts library.

Why routing is a compliance control

Federal law does not mention lead routing. It regulates conduct, and routing determines conduct. Section 3604 of Title 42 makes it unlawful to refuse to rent after a bona fide offer or to make a dwelling otherwise unavailable, and to discriminate in the terms, conditions or privileges of a rental, because of a protected characteristic.¹ HUD's regulation on refusals adds specific examples, among them using different qualification criteria, applications, fees or approval procedures.⁵

An inquiry is where those differences start. If one inbound caller is told a home is available and another is told it is not, or one is quoted a deposit and another is not, the difference exists before anyone applies. HUD's regulation on availability makes it unlawful to give inaccurate or untrue information about availability because of a protected characteristic. It lists limiting information about suitably priced dwellings, and it covers false information given to testers who are not actually seeking housing.²

Three routing facts matter for a multi-market operator.

• Who sees the lead. Whoever receives it applies a script, or does not. A routing rule that sends inquiries to different people with different habits produces different answers unless the answers are standardized.
• How fast it gets a reply. Speed differences that follow a protected characteristic, or a proxy for one such as a name, a language or a neighborhood, are the kind of pattern a tester comparison is designed to find.
• What gets recorded. If you cannot show what each inquirer was told, you cannot show that treatment was uniform.

Steering and differential treatment: the regulations

HUD's regulation on steering, 24 CFR 100.70, lists practices that include discouraging a person from inspecting or renting a dwelling because of a protected characteristic, communicating that a person would not be comfortable or compatible with existing residents, and assigning a person to a particular section of a community or a particular floor.⁶ These apply to conversation and conduct, not only to written ads.

The regulation on different treatment, 24 CFR 100.60(b), covers failing to consider a bona fide offer, charging different rental charges, and using different qualification criteria, applications, fees, credit analysis or approval procedures.⁵ In an inquiry workflow those map to specific moments:

Advertising rules and what happened to HUD's 2024 guidance

The advertising rule is 24 CFR 100.75. It applies to all written or oral notices and statements by people in the rental business, including signs, flyers and applications. Its examples include using words, phrases, photographs or symbols that convey that dwellings are not available to a group, selecting media or locations that deny segments of the market information about housing, and expressing a preference or limitation to agents or employees.⁴ The statute separately reaches the making or publishing of notices, statements and advertisements for a rental.¹ Because the rule covers oral statements, the words on a phone call and in a text reply are within its reach.

On April 29, 2024 HUD issued guidance on applying the Act to advertising through digital platforms. HUD's Office of Fair Housing and Equal Opportunity (FHEO) withdrew that guidance effective September 17, 2025, and published the withdrawal list in the Federal Register on April 6, 2026 (91 FR 17291).³ The notice says the withdrawn documents "should not be relied upon as authoritative," and it says that actions that do not comply with the text of the Act remain subject to HUD enforcement.³

Two points follow for a lead operation. First, the withdrawal removes an interpretation, not the rule. Sections 100.75 and 100.80 remained in the eCFR when I read them on October 13, 2026.⁴² Second, the same notice withdrew FHEO's February 2024 memorandum on source of income testing, and a July 2026 notice from HUD's Office of General Counsel (91 FR 44867) withdrew its November 2024 document on source of income restrictions and its 2016 criminal records guidance.³⁷ Operators who built ad templates around any of those documents should check what the template relies on, because the underlying state rules in the next sections did not change.

Written criteria at inquiry, source of income and criminal history

Federal law does not require you to publish screening criteria at first contact, but several state laws require written notice of criteria before a fee or before information is collected. Uniform written criteria are also the easiest evidence that every applicant was held to one standard. Our guide to tenant screening rules covers the federal screening framework.

The table below summarizes four states, chosen because they show different kinds of rule. It is not a survey. Check the current statute for each market, and see the state comparison.

Sources: the statutes cited in each row, read October 13, 2026. For New Jersey I read the chaptered act, P.L. 2021, c. 110, and did not check for later amendments.

The federal Fair Housing Act lists seven protected classes, and source of income is not one of them. HUD's own document on source of income restrictions was among those withdrawn in 2025, so source of income is a state and local question.¹⁷ An operator with homes in several states needs a per-market version of every ad template and every script.

Fee disclosure in the listing

The FTC's Rule on Unfair or Deceptive Fees, 16 CFR part 464, requires total price disclosure, but its coverage is limited to live-event tickets and short-term lodging.¹³ It does not reach a standard long-term lease of a house. Fee disclosure for those leases comes from state and local law and from the state rules on screening charges above, such as Washington's cap on screening costs and Oregon's refund and frequency rules.⁹¹⁰

For routing, the practical point is consistency. If the listing, the first text reply and the application page quote different amounts for the same home, an inquirer who compares them has a complaint, and an inquirer who does not compare them was still treated differently. Our guide to rental junk fee laws tracks the state rules.

Testing evidence and what enforcement looks like

The Justice Department has run a Fair Housing Testing Program since 1991, with testing starting in 1992. Testers pose as prospective renters, borrowers or patrons without genuine intent to transact. As of the page's February 27, 2025 update, the Department reports 111 pattern or practice testing cases resolved since 1992, with more than $15.3 million recovered, including over $2.3 million in civil penalties.¹⁴

A case that tracks the inquiry stage is the 2021 settlement with Village Realty of Staten Island Ltd. and a rental agent. The Justice Department announced on March 30, 2021 that the settlement, in the form of a consent decree needing approval from the U.S. District Court for the Eastern District of New York, would resolve claims that the agent treated African Americans who inquired about rentals less favorably than similarly situated white persons.¹⁵ The complaint alleged that the agent told African-American testers about fewer units, offered white testers rental discounts and chances to inspect units, mostly offered African-American testers units in racially mixed neighborhoods, and made more encouraging comments to white testers.¹⁵ The Department said the company was legally responsible because the agent acted as its agent.¹⁵

The terms were a $15,000 settlement fund for victims, a $2,500 civil penalty, a ban on further discrimination, nondiscriminatory standards and procedures, fair housing training and periodic reports to the Department.¹⁵ These were allegations resolved by settlement, not findings by a court.

Three features of the case apply to lead handling. The conduct occurred in answering inquiries, not in lease terms. Each alleged difference (number of units, discounts, inspection opportunities, neighborhoods, tone) is something a script, a unit list and a log can standardize. The employer was held responsible for the employee, which is why an operator with many agents and several markets cannot rely on each agent's judgment.

Routing designs and their trade-offs

I found no source that ranks routing designs for fair housing risk, so what follows is an operating analysis, not a legal rule. The risks come from the regulations above. None of the designs is unlawful as such. Each is safer when it is paired with a standard script and a log.

Source: author's analysis based on 24 CFR 100.60, 100.70 and 100.80. Not a legal ruling.

Two further design choices carry more risk than the routing method. Automated first replies, whether generated or templated, must not make statements about the neighborhood or the kind of resident, which 24 CFR 100.70(c) treats as steering when tied to a protected characteristic.⁶ And any rule that holds back certain leads for "qualification" before a reply should apply the written criteria to everyone, not a judgment call based on the name or the phone number.

On response standards, set one target time for every inquiry in every queue and measure it. The rule is not a number of minutes. The point is that the same standard applies to every inquirer and that you can show the log. Compare actual response times across languages and markets each month. If a gap appears, treat it as a staffing problem to fix before a tester finds it.

Spanish-language inquiries and limited English proficiency

National origin is a protected class under the Act.¹ In my analysis, a language-based difference in how inquiries are handled, such as a slower queue or fewer homes offered, carries a risk of being read as differential treatment tied to national origin. I found no court or agency source that settles the point, so treat it as a risk to manage rather than a stated rule.

HUD's guidance on this subject is no longer in effect. The Office of General Counsel's guidance on Fair Housing Act protections for persons with limited English proficiency, dated September 15, 2016, is on the list HUD withdrew effective September 25, 2025, and the July 17, 2026 notice says withdrawn documents should not be relied upon as authoritative.⁷ The April 2026 FHEO notice also withdrew HUD's January 22, 2007 Title VI guidance on limited English proficiency for recipients of federal financial assistance.³ I did not find a HUD replacement for either document.

The statute and the regulations are unchanged, so the 2016 withdrawal changes what HUD tells you, not what the Act prohibits.¹⁵ Operators commonly handle this by answering in the language of the inquiry when a bilingual employee is available, using the same facts and criteria in each language, and not asking about immigration status to screen at the inquiry stage. That last practice is an operator choice that I could not tie to a specific federal rule in the sources I read, so confirm it with counsel for your markets.

Texting and call consent for leads

Lead handling usually moves to text quickly. The FCC's rules at 47 CFR 64.1200 govern consent for autodialed or prerecorded calls and texts, and a called party may revoke consent by any reasonable method, including replying "stop." The rule requires revocation to be honored within a reasonable time not to exceed ten business days.¹⁶

On September 30, 2026 the FCC adopted a Report and Order (FCC 26-67, released October 1, 2026) that lets callers treat a revocation as applying only to the category of informational robocall it addressed and lets callers designate an exclusive means of revoking. It also seeks comment on the timeframe for honoring revocations.¹⁷ I did not confirm its effective date, because the order says the comment dates run from Federal Register publication. See our TCPA texting guide for the current status.

The fair housing link is again uniformity. A text opt-out that is honored for one lead and ignored for another is a consent problem and a record of different treatment.

What to do now

• Write one reply template per market that states the home, rent, fees, availability, screening criteria and how to apply. Use the same template for every inquiry channel. Load the starting versions from the scripts library.
• Remove any listing or reply language that states a preference or limitation tied to a protected class, a voucher, a subsidy or a criminal record. Check each market's state rule before reusing a template across states.
• Do not ask about criminal history at first contact in markets that bar it, and give the written criteria notice before collecting a fee where state law requires it.
• Make the listing fee, the first reply and the application page quote the same amounts.
• Pick a routing design, document it, and give every queue the same inventory, criteria and target reply time.
• Log, for every inquiry, the time received, time answered, who answered, the homes sent and the criteria sent.
• Each month, compare response times by market and by language. Investigate gaps.
• Place a "stop" handler on every text channel and apply opt-outs the same way for every lead. Check the FCC order's effective date before changing your process.
• Have each agent read the steering examples in 24 CFR 100.70(c), and have a manager sample calls and texts against the script.
• Run your own test: send the same inquiry in English and Spanish, and under different names, and compare what comes back. Keep the results.
• Walk the tenant lead to lease playbook against your current process and fix each gap.
