A 55 pound dog called Biscuit was denied on a Tuesday.

Two years old, mixed breed, five pounds over the weight limit. The agent forwarded the application, got a one word answer back, and sent the decline that afternoon. Total time spent on the decision: under a minute.

The applicant leased four blocks away instead. She is still there. Biscuit has not damaged anything.

Nothing about that Tuesday felt like a mistake. A rule existed, the dog broke it, the agent applied it. That is what a working process looks like from the inside.

But what did anyone actually know about that animal? A weight. That was the entire file. Nobody asked whether Biscuit had ever damaged a unit, bitten anyone, or lived indoors before, because nothing in the process asked.

By the end of this you will know what a real screening file contains, where screening stops and fair housing begins, and how to make a decision that still holds up eighteen months later.

The Number That Should Change Your Mind First

Most operators screen pets because they believe pets cause expensive damage. The data is more complicated than that, and it matters for how you design the process.

Two industry surveys give very different answers. PetScreening's December 2024 report found that rental housing professionals reported an average of $592 in pet related damage per unit, and 28% of pet occupied units incurred pet damage. The 2021 Pet-Inclusive Housing Report, a survey of 1,299 residents and 551 owner operators, found that just 9% of renters acknowledged their pets caused damage, with an average repair bill of $210.

Worth knowing who ran that second one: Michelson Found Animals and HABRI, both pet welfare organisations. So treat it as the pet friendly side's best case rather than a neutral number. The Pet-Inclusive Housing Initiative itself notes the true cost likely sits somewhere between the two figures.

The two estimates differ sharply, but both suggest damage frequency and severity vary substantially. That makes screening less about predicting an average repair bill, and more about applying a consistent process to identify documented risks and keep an accurate record of the animals on the property.

What You Are Actually Screening For

Three things, and they are different jobs.

1. Finding the animals you do not know about. PetScreening's 2026 survey of 673 property managers found that only 43% of renters report owning a pet, against 71% of US households overall, and identified unauthorized pets as the number one pet related challenge reported by onsite teams. A screening step at application is one of the best opportunities to get an accurate answer.

2. Catching the outlier. Not the average dog. The one with a documented bite history, or the one whose owner has been evicted over an animal before. That is a small number of applications and it is the entire justification for the process.

3. Making the decision consistent. This is the one operators undervalue, and it is the one that protects you. A denial you can explain against written criteria is defensible. A denial that came down to how a leasing agent felt about a breed is not.

What To Verify

A real screening file has six things in it. None of them is a weight.

1. Vaccination and licensing records:
   Vaccination records required by applicable law or your written pet policy, plus any local licensing your jurisdiction requires. Objective, verifiable, and the same for every applicant.

2. Spay or neuter status:
   Not a pass or fail criterion for most operators, but worth recording.

3. Bite or incident history:
   Ask directly. Ask in writing. An applicant who discloses a past incident and explains it is giving you more to work with than one who says nothing.

4. Prior rental history with the animal:
   This can be one of the most useful pieces of information in the file, because it gives you evidence about the animal's actual history in a rental setting. A previous landlord who confirms the animal lived there for two years without a complaint tells you something a breed profile never will. Ask for it the same way you ask for a rental reference on the human.

5. Photographs:
   Two or three, current. Useful for identification later when a different dog turns up in the unit.

6. A signed pet addendum acknowledging the rules:
   Screening that does not end in a signed document has not produced anything you can enforce.

Some operators use a third party screening platform to collect this. Reasonable, particularly across multiple sites, but it is not the point. The point is that the same six things are collected for every applicant with an animal, in the same order, and stored where someone can find them in eighteen months.

Where This Stops Being A Pet Question

Two boundaries worth being clear about.

1. Do not run assistance animals through pet screening:
   An animal that qualifies for a reasonable accommodation under fair housing law is not a pet. Breed and weight restrictions that apply to pets cannot simply be applied to a qualifying assistance animal. If there is a concern about the specific animal, the assessment must be based on objective evidence about that animal's actual conduct, not assumptions about breed, size or weight. And you cannot charge pet fees for it.

2. Do not ask for unnecessary medical information:
   If an applicant requests an assistance animal as a reasonable accommodation and the disability related need is not apparent or already known, the housing provider may be able to request limited information needed to evaluate the request. That does not mean asking for a diagnosis, medical records, or a detailed account of the person's health. Keep that review separate from ordinary pet screening.

Worth flagging: HUD withdrew its assistance animal guidance notices effective September 2025, so the detailed federal framework operators relied on is no longer in force. The Fair Housing Act remains in force, while state and local fair housing laws may impose additional requirements. That is a separate post, and it is the one to read before handling a live request.

Write Your Criteria Down Before You Need Them

Here is the test that decides whether your process survives a complaint.

If two applicants with similar animals apply at two of your sites in the same week, do they get the same answer? If the honest response is "probably not," that is not a screening process. That is a series of individual opinions, and the pattern across them is what an investigator looks at.

So write the criteria down. Something like:

Applicants with animals must provide vaccination records required by applicable law or this policy, licensing where required, disclosure of any bite or incident history, and a rental reference covering the animal. Applications are evaluated against the property's written pet criteria and applicable law. Any decision, including the specific reason for approval or denial, is recorded in the applicant file.

Notice what that does. It gives your agents a script, it gives you a consistent record, and it turns "over the limit, deny?" into a decision with a written basis behind it.

And decide deliberately whether weight and breed limits belong in your criteria at all. They are common: the Pet-Inclusive Housing Report found that while 77% of pet friendly rentals allow dogs, half of them have weight limits, averaging 45 pounds. But PIHI's 2025 data also found that while 79% of rental properties claim to allow pets, fewer than 10% qualify as pet inclusive with no breed or weight restrictions, and 72% of renters report difficulty finding pet friendly housing. If your units sit vacant longer than the market, a 50 pound cap is worth examining as a leasing decision, not just a risk one.

Worth 30 Minutes, Or Worth Nothing

If you run one site and you personally approve every animal, a checklist and a folder will do this properly. Where it falls apart is four sites, four agents, and no shared record of what was asked or what was decided. That inconsistency is the thing a complaint investigation finds, and it is invisible until someone goes looking. RIOO keeps screening criteria and decision records against the application itself, so the same questions get asked at every site and the reasoning is still there in eighteen months.

Three Things To Remember

• One: A weight limit is not a screening process. It is one data point, and it tells you little about an individual animal's actual history or conduct.

• Two. Rental history with the animal is one of the few things in the file that gives you real evidence, and it is the item most often skipped.

• Three. The decision and the record both matter. Written criteria plus a written reason make the process more defensible.

One Last Thing

Go back to Biscuit.

The agent asked the right question in the wrong form. She wanted to know whether this dog was a risk. What she actually had was a number that told her nothing about risk at all, because nothing in her process had asked for anything else.

Deny Biscuit and you lose a lease over a scale reading. Approve Biscuit and you have approved an unknown animal with no file behind it. Both outcomes are bad, and both come from the same gap: the questions were never written down, so they were never asked.

The wider version of this shows up across the whole application, not just the pet part. Screening criteria that survive a complaint is the same problem at full size.

If the part that worries you is consistency, the same question producing different answers at different sites, no record of who decided what, that is what RIOO's tenant acquisition and screening is built for. Have a look, or don't. Writing your criteria down costs nothing and tells you whether you have a problem either way.

FAQ

Can I refuse a pet for being over my weight limit?
For an ordinary pet, generally yes, where the limit is stated in your written criteria and applied consistently. It cannot simply be applied to a qualifying assistance animal.

Do I need a pet screening service?
No. You need the same items collected consistently. A service makes that easier across multiple sites.

Can I ask a previous landlord about the animal?
Yes, the same way you would ask about the tenant. It is one of the most useful references you can get.

What if the applicant says the animal is an ESA?
Pause ordinary pet screening and determine whether the applicant is requesting a reasonable accommodation for an assistance animal. That follows a different workflow under fair housing law.
