They have to tell you the rules

Washington: their own screening criteria are your best document

Applicants in this state are entitled to know what a landlord screens on before they apply. Very few people ever read that document, and it is frequently the single most useful piece of paper in the whole exchange.

Three places a refusal can go

Most states offer two. Knowing which is nearest to you is worth a few minutes.

Choosing one does not close the others, and where more than one set of rules covers the same facts, whichever gives you more governs that point. Nothing local can subtract from the national floor.

Five things to collect and do

All of it before anything formal, and all of it quick.

If a notice arrives instead of an answer

Washington gives renters protections governing the ending of a tenancy and the notice owed before it happens. Those sit apart from the animal question and have forums of their own, yet the two converge precisely when a landlord sets out to be difficult.

So a notice, or a steep increase, landing soon after you asked belongs in both places rather than one. The timing counts as a fact by itself, and it stays one however plausible the market explanation offered alongside.

Whichever route you take, pay what you owe throughout. A missed payment gives them a termination ground entirely unconnected to your request, and being right about the animal repairs none of it.

Questions from Washington

They never gave me any screening criteria.
Ask for them in writing, and keep whatever comes back — including nothing. A refusal resting on a standard that was never disclosed is in a much weaker position than one resting on a rule you were told about before you applied.
Their criteria say no animals over twenty-five pounds.
That is the provision your request seeks to lift, not an answer to it. A refusal has to identify something your own animal has done or a genuine hazard it presents, spending proved excessive at that address, or a change reshaping how the property runs.
Should I complain to the city or the state?
Where a municipal civil rights office serves your address, begin with it: nearest to the landlord and usually swiftest. Failing that, the state commission, with the federal office running in parallel. Choosing one shuts none of the rest.
My housing came with a seasonal farm job.
Quarters connected to work may be examined as housing, as a term of the employment, or as both together. Harvest finishes well before a dispute does, which is why this one should be put early and every message kept.
