## The city where the exemption actually matters

Shoreline rents at 33.7%: around 8,200 of 24,420 occupied units on the
2020-2024 American Community Survey five-year estimate. That is slightly below
the statewide 36.2%, and a long way below Seattle immediately to the south at
56.3%.

The gap is a matter of built form. Shoreline is predominantly single-family,
and a substantial share of what is let here is attached to a house somebody
else lives in: a converted basement, a garage conversion, a purpose-built
accessory unit in the garden.

That arrangement is the one situation in Washington where the accommodation
duty may not apply at all, which makes it the first thing a Shoreline tenant
should establish rather than the last.

## What RCW 49.60.222(2) leaves out

Most of these guides describe what the accommodation duty requires. Here it is
worth being equally clear about where it stops.

RCW 49.60.222(2) sets out the modification duty at (2)(a) and the
accommodation duty at (2)(b), and then provides that neither applies to two
categories. The second is the one that matters in Shoreline:

> "rooms or units in dwellings containing living quarters occupied or intended
> to be occupied by no more than four families living independently of each
> other if the owner maintains and occupies one of the rooms or units as his
> or her residence."

A basement flat in a house whose owner lives upstairs can sit squarely inside
that description. Where it does, the landlord is not under the state
accommodation duty, and a refusal is not an unfair practice under (2)(b).

The first exemption covers a single-family house let by an owner with an
interest in no more than three such houses at a time, where the letting used
no salesperson or broker and was not advertised.

## How to tell whether it fits

The conditions are specific, and a landlord asserting the exemption is making
factual claims that can be checked.

The dwelling must contain living quarters for no more than four families
living independently of one another. The owner must both **maintain and
occupy** one of those rooms or units as their residence, not merely own the
property, and not have moved out last year while keeping an address there.

Several nearby arrangements fall outside it. A detached rental cottage on the
same lot is not a unit in the same dwelling. A house divided into five units
exceeds the limit. An owner who has moved away and lets both halves of a
duplex does not occupy one of them.

Where any of those describe the situation, the ordinary rules apply in full.

## What survives the exemption

Even where the exemption does apply, it is narrower than landlords sometimes
assume. It disapplies subsections (2)(a) and (2)(b), and nothing else.

The other unfair practices in RCW 49.60.222 remain in force, including the
prohibition at subsection (1)(g) on making, printing, circulating, posting or
mailing any statement, advertisement, sign or application form indicating an
intent to discriminate. An advertisement for the flat that announces the
disabled need not apply is unlawful regardless.

The whole of the residential landlord-tenant chapter also continues to apply.
Deposits, checklists, deadlines and instalment rights do not turn on the fair
housing exemption at all.

## Where the duty does apply

For the majority of Shoreline lettings (professionally managed buildings,
detached houses let by owners living elsewhere, anything advertised through an
agent), the position is the ordinary one.

RCW 49.60.222(2)(b) requires a landlord to give way on a rule, policy,
practice or service where that is what a disabled tenant needs for the same
use and enjoyment of the home as anyone else. WAC 162-38-100(3) prevents a
no-pet policy being applied to an assistance animal. And WAC 162-38-100(5)
does not permit an animal-specific deposit alongside the standard cleaning or
damage deposit, with subsection (4) preserving that ordinary deposit where it
falls on every tenant equally.

The trained-animal question does not arise either way. RCW 49.60.040(25)
contains that test and then removes itself from RCW 49.60.222 through
49.60.227 for housing accommodations and real estate transactions, which is
the state's fair housing law in full.

## The deposit rules apply to everyone

This is worth stating plainly, because accessory-unit tenancies are where
paperwork is thinnest and assumptions run in the landlord's favour.

RCW 59.18.260 bars taking any deposit unless there is a written rental
agreement and a checklist recording the condition and cleanliness of the unit,
signed and dated by both sides at the start. Skip it and the sum is owed back
to the tenant.

RCW 59.18.280 then requires a full and specific written statement of anything
retained, with copies of estimates received or invoices paid for the damage
charges, delivered within 30 days of the tenancy ending and the unit being
vacated, together with any refund. Ordinary wear may not be charged for. A
landlord who lets the deadline pass loses the right to keep any of it.

None of that depends on whether the owner lives upstairs.

## Spreading the cost, and the charge that cannot be stacked

Two further provisions apply to accessory-unit tenancies whatever the fair
housing position turns out to be.

RCW 59.18.610 gives a tenant who asks in writing the right to pay deposits,
nonrefundable fees and last month's rent across three consecutive equal
monthly instalments on a term of three months or longer. No fee may be added
and no interest charged for using it, and a landlord who refuses is exposed to
a statutory penalty of one month's rent plus reasonable attorneys' fees.

RCW 59.18.285 governs what the money may be called: nothing nonrefundable can
be recorded as a deposit, and a fee that is genuinely nonrefundable has to be
identified as such in a written agreement. Absent that, it counts as a
refundable deposit.

Where the accommodation duty does apply, WAC 162-38-100(5) additionally rules
out an animal-specific deposit sitting alongside the ordinary cleaning or
damage deposit, with subsection (4) preserving that ordinary deposit provided
every tenant pays it.

## Where to complain

Where the accommodation duty applies and has been refused, housing complaints
go to the Washington State Human Rights Commission. RCW 49.60.230(2) allows
six months for discrimination complaints as a class and then treats real
estate separately, giving a matter under RCW 49.60.222 through 49.60.225
twelve months from when the practice occurred or terminated. Filing is through
the commission's online portal, with a toll-free line on 1-800-233-3247.

King County runs a Civil Rights Program covering housing among other areas, at
civilrights@kingcounty.gov or 206-263-2446.

Where a landlord asserts the owner-occupancy exemption, ask them to put that
in writing along with the basis for it. It is a factual claim about the number
of units and where the owner actually lives, and it either holds or it does
not, which is a far better position than an argument conducted on
assumptions.

It is also worth asking early rather than late, before a deposit is paid or a
pet charge posts. The answer determines which of two quite different sets of
rules the tenancy runs under, and every subsequent conversation is easier
once that is settled.

a defensible letter contains.

## What Shoreline landlords can and cannot do

**Cannot:**
- Cannot apply the trained-task definition of a service animal to a housing request, because RCW 49.60.040(25) states that the subsection does not apply to RCW 49.60.222 through 49.60.227 for housing accommodations or real estate transactions
- Cannot refuse to make reasonable accommodation in rules, policies, practices or services where that accommodation may be necessary to afford a person with a sensory, mental or physical disability equal opportunity to use and enjoy a dwelling
- Cannot apply a no-pet policy to the assistance animal of a person with a disability, under WAC 162-38-100(3)
- Cannot charge a pet deposit on top of any standard cleaning or damage deposit, which WAC 162-38-100(5) makes an unfair practice outright
- Cannot demand that the animal be removed unless its presence, behaviour or actions pose an unreasonable risk of injury or harm and a reasonable attempt to correct that behaviour has already failed, under WAC 162-38-105
- Cannot treat staff or neighbour annoyance at the animal as the kind of risk that justifies removal, and cannot exclude it from the whole property over a risk confined to part of it
- Cannot inquire into matters personal to a disabled applicant beyond what is necessary and appropriate to the landlord-tenant relationship, under WAC 162-38-110
- Cannot require a waiver of rights or a hold-harmless as a condition of the transaction because a disabled person or a person with an assistance animal will occupy the property, under WAC 162-38-120
- Cannot collect any deposit at all without a written agreement and a signed move-in checklist, or keep any of it without a documented statement within thirty days

**Can:**
- May charge its standard cleaning or damage deposit, provided the same deposit is enforced equally on every tenant, which WAC 162-38-100(4) expressly permits
- May ask for information supporting the disability and the disability-related need for the animal where neither is readily apparent
- May hold the tenant responsible for damage the animal actually causes, substantiated at move-out by invoices or estimates like any other charge
- May fall outside the accommodation duty entirely in two narrow cases under RCW 49.60.222(2): an unadvertised single-family house let by an owner holding no more than three, and an owner-occupied dwelling of no more than four units, though the section's other prohibitions still apply

## Frequently asked questions

### I rent a basement flat and the owner lives upstairs. Does the accommodation duty apply?

Possibly not, and this is the one Shoreline question worth resolving first. RCW 49.60.222(2) provides that the modification and accommodation duties in (2)(a) and (2)(b) do not apply to rooms or units in a dwelling containing living quarters for no more than four families living independently, where the owner maintains and occupies one of them as their residence. A purpose-built accessory unit in a house the owner lives in can fall inside that description.

### What still applies if the exemption does cover my unit?

The exemption is limited to subsections (2)(a) and (2)(b). The other unfair practices listed in RCW 49.60.222 remain in force, including the bar in subsection (1)(g) on advertisements, notices and application forms indicating an intent to discriminate. The whole of chapter 59.18 RCW also continues to apply, so the deposit checklist requirement, the 30-day accounting deadline and the instalment right are unaffected.

### How do I tell whether the exemption fits my building?

By counting units and checking occupancy. The exemption requires a dwelling with living quarters for no more than four families living independently, and requires the owner to both maintain and occupy one of them as a residence. A landlord who has moved out, or who owns a detached rental house on the same lot rather than a unit in the same dwelling, is describing a different arrangement from the one the statute exempts.

### My landlord does not live here. What then?

Then the ordinary rules run. RCW 49.60.222(2)(b) requires reasonable accommodation where necessary to give a disabled tenant equal use and enjoyment of the home. A no-pet policy has no purchase on an assistance animal under WAC 162-38-100(3), and WAC 162-38-100(5) rules out an animal-specific deposit sitting beside the cleaning or damage deposit.

### Does the animal need training in Shoreline?

No, wherever the accommodation duty applies. RCW 49.60.040(25) sets out a trained dog-or-miniature-horse test and excludes comfort and companionship from work or tasks, then removes that subsection from RCW 49.60.222 through 49.60.227 for housing accommodations and real estate transactions. Those sections are the state's fair housing law in full, so training is not part of the housing question.

### What has to be returned to me at the end of the tenancy?

A documented account of the deposit within 30 days of the tenancy ending and the unit being vacated, under RCW 59.18.280, with copies of estimates received or invoices paid substantiating any damage charges, plus the balance. Ordinary wear cannot be deducted for. This applies to accessory-unit tenancies in the same terms as to apartment tenancies, and a landlord who misses the deadline forfeits the right to retain any of it.

### How much of Shoreline rents?

About 33.7%, or roughly 8,200 of 24,420 occupied housing units, on the 2020-2024 American Community Survey five-year estimate, slightly under the statewide 36.2%, and far below Seattle immediately to the south at 56.3%.
