Are you looking at a rent increase for 2026 and wondering which notice period actually applies? Are you stuck between state law, Olympia city rules, and a lease renewal date that is getting close? I hear this confusion a lot, especially from landlords who are trying to stay lawful without slowing down the day-to-day work of running a rental.
The benefit of understanding these notice rules early is simple: you can plan better, avoid preventable disputes, protect cash flow, and keep your paperwork clean. A notice served on the wrong timeline can upset a tenant, delay the increase, and create extra cost that wipes out the gain you were trying to make in the first place.
When I review olympia rent increase notice rules, I do not look at one number in isolation. I look at state law, local city rules, the size of the increase, the type of tenancy, and whether the rental is even subject to the statewide cap. That is the only way the timeline starts to make sense.
In 2026, this matters even more because Washington now has a statewide annual cap for many residential rentals, and Olympia still has its own local notice windows and tenant-rights rules on top of that. So the real question is not just “Is it 90 days?” The real question is “Which rule applies to this property, this tenant, and this increase?”
Why do landlords keep seeing three different notice periods?
The reason is that two layers of law are working at the same time.
At the state level, Washington requires at least 90 days’ prior written notice for most rent increases. That is the general baseline under RCW 59.18.140. The same state law also says the increase cannot take effect before the current rental term is complete. So even before Olympia enters the picture, landlords already have a timing rule to follow.
Then Olympia adds longer local notice periods for bigger increases. Under Olympia’s rental housing code, a landlord must give at least 120 days’ notice for an increase of more than 5%, and at least 180 days’ notice for an increase of 10% or more. The city also ties extra tenant rights to increases that total 7% or more over a 12-month period.
That is why you keep seeing 90, 120, and 180 days. They are not random numbers. They are different legal triggers.
I usually think about it this way:
- 90 days is the statewide starting point for many ordinary increases
- 120 days is the Olympia rule once the increase goes above 5%
- 180 days is the Olympia rule once the increase reaches 10% or more
- 30 days can apply in a subsidized tenancy where the tenant’s portion of rent changes based on income or household circumstances
Here is the cleanest way to read it:
| Increase situation | Main rule to check | Minimum notice |
|---|---|---|
| Standard residential increase, most cases | Washington state baseline | 90 days |
| Olympia increase above 5% | Olympia local code | 120 days |
| Olympia increase of 10% or more | Olympia local code | 180 days |
| Subsidized tenancy tied to income or household circumstances | State and local subsidized exception | 30 days |
That table looks simple, but the real work is in figuring out which box your property belongs in.
What does Washington state require before Olympia’s local rules apply?
Before I even look at the Olympia calendar, I start with the Washington rules that now shape nearly every rent increase file.
First, for rentals covered by RCW 59.18.700, a landlord may not increase rent during the first 12 months after the tenancy begins. That rule catches people off guard because some owners think only the notice period matters. It does not. Timing starts with the first-year bar, then moves to the annual cap, and only after that do I worry about the notice window.
Second, after that first 12-month period, covered rentals are limited during any 12-month period to the lower of 7% plus the Consumer Price Index or 10%. For calendar year 2026, the Washington Department of Commerce announced the cap at 9.683%, effective from January 1 through December 31, 2026. That single number changes how I read Olympia’s 180-day rule, because a 10% increase may be lawful only if a valid exemption applies.
Third, Washington now requires landlords to use a rent increase notice form that is substantially the same as the form in RCW 59.18.720. The statute also says the notice must comply with the day-count rules in RCW 59.18.140 and be served in accordance with RCW 59.12.040. In plain language, that means a short text message or a casual email is not something I would rely on for a 2026 increase file.
How does the 2026 state cap change the picture?
This is where a lot of owners make a wrong turn.
If a standard Olympia rental is covered by the statewide cap, the 2026 ceiling is 9.683%. So if I am looking at a 10% increase on a covered unit, I do not stop at the city’s 180-day notice rule. I first ask whether the increase is even allowed under state law. If it is not covered by an exemption, then the issue is not just notice. The issue is legality.
A quick example shows why this matters. Say a landlord has a covered Olympia rental at $2,000 per month and wants to move to $2,200. That is a 10% increase. The city’s local code tells me that a 10% or higher increase needs 180 days’ notice. But the state cap for 2026 is 9.683%, so the landlord would also need a valid exemption to make that increase lawful. Without the exemption, the longer notice period does not fix the larger problem.
This is why I tell landlords that the notice period is only one part of the answer. The percentage, the 12-month lookback, and the exemption question come first.
What has to be on the notice itself?
Under RCW 59.18.720, the state form is not just a blank line for the new rent. It is meant to tell the tenant what is changing, how much the change is, and whether the landlord is using the ordinary cap or an exemption. The form language also makes clear that the rent amount includes recurring and periodic charges identified in the rental agreement for use and occupancy of the unit.
That means the notice should clearly show:
- the effective date
- the percentage increase
- the dollar increase
- the new total monthly amount
- whether the increase is below the state maximum, at the maximum, or based on an exemption
- supporting facts if an exemption is claimed
Olympia adds another layer. The city code says the increase notice must specify the amount of the increase, the total amount of the new rent, the date the increase becomes effective, the rationale for the increase, and the tenant’s rights under the economic displacement relocation assistance program when those rights are in play. That local requirement is one of the easiest places to slip up.
Do rent-related fees count too?
Yes, and I would not treat that lightly.
The state form in RCW 59.18.720 says the tenant’s “rent or rental amount” includes all recurring and periodic charges identified in the rental agreement for the use and occupancy of the unit. So if a recurring housing charge shows up every month under the lease, I would review it as part of the increase analysis rather than assuming only base rent counts.
A real-life example helps. If a lease says the tenant pays $1,900 in base rent and a recurring monthly housing charge that is part of occupancy, I do not just test the increase against the $1,900. I look at the full recurring housing amount described by the agreement, then calculate the percentage change. That keeps the file closer to what the statute is actually trying to regulate.
When does the 90-day rule apply in Olympia?
For many ordinary residential increases, 90 days is still the starting point because RCW 59.18.140 requires at least 90 days’ prior written notice in most cases. In Olympia, this window is most useful when the increase does not cross the city’s longer local thresholds. In practical terms, I treat 90 days as the baseline for increases that do not go above 5%, unless a special rule changes the timeline.
That does not mean every Olympia increase uses 90 days. It means the state baseline is still present, but the local code can push the timeline longer as soon as the percentage gets larger. This is where landlords sometimes think the city replaced the state rule completely. It did not. The city added more notice for certain increases.
What does that look like in real life?
Suppose a covered Olympia rental is at $2,100 per month and the landlord wants a 4% increase for 2026. The increase would be $84, bringing the new monthly amount to $2,184. That percentage is under the 2026 state cap and does not go above Olympia’s 5% trigger. So I would usually expect the 90-day state notice rule to control that timing question, along with the requirement that the increase not take effect before the current rental term is complete.
There is also a special case for subsidized tenancies where the amount of rent is based on the tenant’s income or household circumstances. For those tenancies, both state and Olympia materials point to a 30-day written notice rule instead of the general timeline. That exception is narrow, and I would not use it casually on an ordinary market-rate file.
When does the 120-day rule apply?
In Olympia, the 120-day notice rule applies when the increase is more than 5%. That is the local trigger that changes the calendar for many mid-range increases that are still under the 2026 state cap. A lot of owners will spend most of their time in this category because increases between just over 5% and 9.683% are the most realistic range for covered rentals in 2026.
This is also the point where tenant reaction becomes a bigger part of the business decision. The city code says that if a landlord gives notice of intent to increase rent by more than 5%, the tenant may terminate the tenancy before the effective date of the increase by giving at least 30 days’ written notice. If the tenant does that, the tenant owes only prorated rent through the move-out date, and the landlord may not charge fines or fees for ending the rental agreement under that subsection.
That single rule changes how I think about a 6% or 8% increase. It may be lawful. It may even be reasonable. But it can also produce turnover, vacancy, cleaning costs, and re-leasing work that swallow the gain if the tenant was otherwise stable.
Why does the 5% line matter so much?
Because once an increase goes above 5%, it is no longer only about a longer notice period. It also becomes a tenant-decision event.
A simple example makes that clear. Assume monthly rent is $1,950 and the landlord plans a 6% increase. That adds $117 and takes the new amount to $2,067. For a covered rental, 6% is within the 2026 state cap, so the increase may be lawful. But because it is more than 5% in Olympia, I would plan around a 120-day notice window and the real possibility that the tenant may give 30 days’ written notice and move out before the increase begins.
That is why I do not look at rent math alone. I look at:
- the current tenant’s payment history
- whether the tenant has been easy to retain
- what a turn would cost
- how long similar homes stay vacant
- whether the property needs work before re-listing
- how the new price fits the local market
The law tells me what I may do. The numbers tell me whether I should do it at that amount and on that date.
When does the 180-day rule apply?
Olympia requires 180 days’ notice when the rent increase is 10% or more. The city code is clear on that. So if a property is inside Olympia city limits and the landlord is lawfully planning an increase at that level, the longer city timeline needs to be built into the calendar from the start.
But here is the part many people miss: for many ordinary residential rentals covered by state law in 2026, a 10% increase is above the statewide 9.683% cap. So in actual practice, the 180-day rule will often matter most for exempt rentals rather than standard capped rentals. That is not a new city exception. That is just the result of reading the local rule next to the current state cap.
Why this window often matters most for exempt rentals in 2026
Let’s say a landlord has a newer unit where the first certificate of occupancy was issued 12 years or less before the date of the increase notice. State law lists that as one exemption from the statewide limit. In that kind of file, a 10% increase may still be possible under state law if the exemption is valid and properly documented. But because the property is in Olympia, the city’s 180-day notice rule would still apply to that size of increase.
The same logic can come up with some owner-occupied arrangements or certain qualifying nonprofit and low-income housing situations. I do not assume an exemption exists just because an owner says a building is “small” or “partly owner occupied.” I match the facts against the statute first, then I decide whether the cap applies.
What happens once the increase reaches 7% over a 12-month period?
This is one of the most important local rules in Olympia, and it is the one that can surprise landlords who thought they had already done the hard part.
If a rent increase, together with any other increase in the preceding 12 months, totals 7% or more, the tenant may request economic displacement relocation assistance in writing within 45 calendar days after receiving the increase notice. If the tenant makes that request, the landlord must pay relocation assistance within 31 calendar days, and the amount is two and one-half times the tenant’s monthly rent.
This is not a small number. If the tenant’s monthly rent is $2,000, two and one-half times rent is $5,000. If rent is $2,300, that becomes $5,750. That is why I always tell owners to budget the local relocation risk before serving a larger increase notice in Olympia.
How relocation assistance works in practice
Here is a straightforward example. Say a tenant pays $1,850 per month. Last fall the landlord increased rent by 2%. This year the landlord plans another 5.5% increase. On paper, the second notice may not look enormous. But Olympia measures the current increase together with other increases in the preceding 12 months. If the combined change reaches 7% or more, the tenant may ask for relocation assistance.
The city code also says that if the tenant receives timely relocation assistance, the tenant may relocate at any time before the increase takes effect so long as the tenant gives at least 30 days’ written notice and pays prorated rent until leaving. If the tenant stays in the unit until the effective date of the increase, the tenant must pay the increased rent and repay the relocation assistance. In other words, the payment is tied to moving, not to staying.
There are also exceptions. The economic displacement rule does not apply in every situation. The city code lists exceptions that include some same-site owner situations, some shared-owner living arrangements, tenants who have lived in the unit less than six months, short-term rentals, and some subsidized housing situations. I would check those exceptions carefully before assuming the relocation rule applies or does not apply.
Which rentals are exempt from the statewide cap?
This question matters because the notice period and the legality of the percentage are tied together.
Washington’s exemption list includes several situations where the state cap in RCW 59.18.700 does not limit the increase in the ordinary way. Common examples include:
- a dwelling unit with a first certificate of occupancy issued 12 years or less before the date of the increase notice
- certain units owned by a public housing authority, public development authority, or nonprofit organization with regulated rents
- certain qualified low-income housing developments
- a unit where the tenant shares a bathroom or kitchen with the owner who lives there
- a single-family owner-occupied residence where the owner rents no more than two units or bedrooms, including an ADU
- an owner-occupied duplex, triplex, or fourplex where the owner occupied one unit as a principal residence at the beginning of the tenancy and continues in occupancy
What exemptions show up most often for small landlords?
From a practical angle, the ones I see people ask about most are the newer-building exemption and the owner-occupied small-property exemptions.
The newer-building example is easy to picture. If a home received its first certificate of occupancy eight years ago, a landlord may be outside the ordinary statewide cap because that date falls within the 12-year exemption window. But the landlord still has to support the exemption with facts or documents in the notice. That is not optional.
The owner-occupied examples are common too. A landlord who lives in one unit of a duplex, triplex, or fourplex may qualify for an exemption if the owner occupied one of the units as a principal residence at the beginning of the tenancy and continues to live there. Likewise, a single-family owner-occupied residence with no more than two rented units or bedrooms can fall into the exemption list. But I would not guess on these facts. I would document them.
And even when an exemption is valid, Olympia’s local notice rules can still matter. Exempt from the cap does not mean exempt from every city rule.
What mistakes cause the most trouble?
The first mistake is using the state 90-day rule and stopping there. For Olympia rentals, that is often incomplete because the city can require 120 or 180 days depending on the size of the increase.
The second mistake is focusing on the percentage without checking the 12-month history. Olympia’s 7% relocation rule looks at the current increase together with other increases in the preceding 12 months. A landlord who forgets the earlier increase can misread the tenant’s rights.
The third mistake is using weak paperwork. State law now expects a notice form that is substantially the same as RCW 59.18.720, and Olympia expects extra local content such as the rationale for the increase and local relocation-rights language when applicable. A thin notice is where avoidable disputes begin.
The fourth mistake is assuming a 10% increase only needs a longer notice period. In 2026, many standard residential rentals are capped at 9.683%, so a 10% increase usually raises an exemption question first.
The fifth mistake is forgetting the cure rule under state law. If a landlord increases rent above the allowed amount without a valid exemption, the tenant must first give a written demand to cure, and the tenant may terminate the rental agreement before the increase takes effect by giving at least 20 days’ written notice. The landlord may not charge fines or fees for that termination.
