AI leasing assistants: what they can and cannot do for landlords

DoorKeeping team

4 min read

An AI leasing assistant can answer routine questions about a vacant unit, share your fact sheet and book a time for you to approve. It should not decide who gets to rent, quote terms you did not set, or say anything about who would fit a building. The owner stays responsible under the Fair Housing Act for what the tool says, so set limits, read the logs, and keep a person in charge of every decision.

What a leasing assistant does

A leasing assistant is software that replies to people who ask about a rental, by chat, email or text. A good one answers from facts you give it: the address, rent, deposit, date, pet policy, criteria, and how to see the unit. This is different from an assistant that answers your current tenants; for that, see AI replies to tenant messages.

What it can do well

  • Answer routine questions at any hour from your fact sheet.
  • Send your written criteria and the application link to every inquiry.
  • Offer the showing times you set and pass the request to you.
  • Collect names and contact details in the same form for everyone.
  • Flag a message that needs a person, such as a disability or accommodation request.

What it should not do

  • Decide, approve or deny an application on its own.
  • Discuss who the neighbors are, what kind of people live in the building, or whether a family or a single person would suit it. That is steering.
  • Invent terms: a rent, a discount, a pet exception or a move-in date you never set.
  • Say a unit is unavailable when it is not.
  • Answer an accommodation request with a flat no.
  • Handle money, such as a deposit, or send a legal notice, without a person checking.

Why the fair housing risk stays with you

The Fair Housing Act speaks of what is said and done, not which tool said it. It bans refusing to rent or setting different terms because of a protected trait (HUD overview), and it bans statements that show a preference or limit (42 U.S.C. 3604(c)). Giving inaccurate availability information is prohibited, even to a tester posing as a renter (24 CFR 100.80). If your assistant says something to one person and not another because of how they write or what they reveal about themselves, the owner is the one answering the complaint.

Federal agencies have issued guidance on automated tools in housing, and guidance changes. Before you rely on any of it, check HUD's current site. The statute and regulation above do not change with the tool.

Controls to set before you turn one on

  1. Give it a single fact sheet per unit and tell it to answer from that and nothing else.
  2. Tell it to refuse questions about neighborhood demographics, schools as a draw for certain families, or who would fit.
  3. Route every accommodation request, complaint or legal question to you.
  4. Give every inquiry the same criteria and the same application link.
  5. Test it by asking the same question as different people, and read how the answers differ.
  6. Keep the conversation logs for as long as you keep application records, and review a sample each week.
  7. Disclose, in the first message, that the sender is a software assistant, and offer a person.
  8. Respect text rules: no automated texts to a cell phone without consent, and honor STOP (FCC guide).

Example a made-up owner tests an assistant with two messages: "I have two kids, is this good for a family?" and "I am single, is this a quiet building?" The assistant answers the first with "families love this block" and the second with "perfect for professionals." The owner changes the instructions to reply to both with the facts only, such as bedrooms, rent and school district links the owner approved, and tests again.

How DoorKeeping handles it

DoorKeeping connects to Claude and ChatGPT so you, the owner, run your properties by asking. Anything involving money or a legal step waits for your one-tap approval, and tenant emails go out under your control. It is $2 per unit per month, every feature included. DoorKeeping gives no legal advice, so check your state and city rules with your own counsel.

Questions

Can an AI chatbot violate fair housing law?
The law applies to what is said and done about a rental, however it is produced. If the owner uses a tool and it steers or misstates availability, the owner can be responsible.
Should I tell prospects they are talking to AI?
It is a good practice, and your state or city may have its own chatbot rules, so check. Say so in the first message and offer a person.
Can AI approve or deny applications?
It should not. The decision against your written criteria, and any adverse action notice, should come from a person.
