Washington's Department of Commerce publishes one number every summer that every Tacoma landlord repeats to themselves: 9.683 percent, the maximum a rent can legally rise in 2026 under the state's rent stabilization law, House Bill 1217. It shows up in every landlord Facebook group and every template lease circulating online. For a Tacoma property, it is close to irrelevant to the decision that actually matters.
The number that governs whether a rent increase is a smart move in Tacoma sits in a different piece of law entirely, one the state cap never mentions. It is 5 percent, and it lives in the city's own Landlord Fairness Code. Cross it, and a tenant who decides to move instead of paying can require a payment worth two to three months of rent, on top of whatever notice paperwork the state already demands. Stay under it, and none of that applies. The gap between what the state allows and what the city makes expensive is where self-managing owners get caught off guard, usually after the notice has already gone out.
Two Notices Where One Used to Do
Before HB 1217, a Tacoma landlord raising rent needed to meet the notice requirements in RCW 59.18.140, a fairly simple step. As of 2026, the state also requires a Department of Commerce prescribed rent-increase form delivered at least 90 days before the increase takes effect. Tacoma's Rental Housing Code, updated under Amended Substitute Ordinance 29086 on January 1, 2026, layers its own city Notice of Rent Increase form on top of that. City rules require that any notice served under RCW 59.18.030, TMC 1.95, or TMC 1.100 also include the city's separate Notice of Resource document. A landlord who sends a state-compliant notice and stops there has completed roughly half of what Tacoma now expects.
Why 5 Percent, Not 9.683 Percent, Is the Number to Plan Around
The relocation assistance rule inside the Landlord Fairness Code activates once a rent increase reaches 5 percent within a 12-month period. Cross that line, and a tenant who decides not to renew can request a payment calculated as a multiple of the rent in effect at the time of the increase notice.
| Rent increase | Relocation assistance owed if the tenant requests it |
|---|---|
| Under 5% | None |
| 5% up to 7.5% | 2 months' rent |
| Over 7.5% up to 10% | 2.5 months' rent |
| Over 10% | 3 months' rent |
On an $1,800 monthly rent, the difference between a 4.9 percent increase and a 5.1 percent increase is about four dollars a month. The liability difference is roughly $3,600, since two months of rent at that level comes to $3,600 the landlord owes only if the tenant asks for it. HB 1217 would let that same landlord raise rent almost twice as far, up to 9.683 percent, before hitting the state ceiling. In Tacoma, most of the room between 5 and 9.683 percent is legal and expensive at the same time.
A Cliff, Not a Slope
The payment is contingent, not automatic. A tenant has to request it after receiving the increase notice, and then actually decide to relocate rather than pay the new rent. If they request the assistance and then sign a new lease to stay anyway, they owe the money back within 10 days. A landlord who has already paid it out has no shortcut for collecting that repayment beyond the same process used to recover any other debt.
Some owners have discussed staggering rent increases across a year, keeping each individual notice under 5 percent, as a way to avoid the trigger even if the cumulative increase clears it. The code calculates the assistance based on the rent in effect at the time of each individual increase notice, which is why this approach gets debated in local landlord circles. It has not been tested in a Tacoma courtroom, so it sits closer to an open question than a settled workaround.
The License Check That Comes Before Any of This
None of the above matters if the underlying license issue is unresolved. Under the Rental Housing Code, a landlord cannot pursue eviction or raise rent at all without a current City of Tacoma business license, and the unit has to be free of code violations that endanger tenant health or safety under RCW 59.18.060. The threshold for needing a license is low. A business located outside Tacoma is exempt only if it generates less than $4,000 in annual gross Tacoma income, a bar a single rented bedroom clears within a couple of months. Owners can check their own license status against the city's public directory of rental business licenses before serving any notice.
Nobody Checks This Until You're in Court
The state's rent cap is administered proactively. The Department of Commerce publishes it every summer with a landlord resource center attached. Tacoma's Landlord Fairness Code works the opposite way. The code itself states that a landlord's violation is a defense to eviction, which means the mechanism that catches a missed license renewal or an overlooked 5 percent trigger is not a city inspector or a warning letter. It is the eviction hearing itself.
The December 9, 2025 vote to amend the code wasn't quiet, either. Tacoma City Council passed the changes on legislation sponsored by District 2 council member Sarah Rumbaugh, over objection from tenant groups including Tacoma for All, whose steering committee member Kiss'Shonna Curtis argued the changes would push residents toward homelessness, according to King 5's coverage of the vote. The council described the update as a balance between landlord and tenant interests. Whatever side of that debate a given owner falls on, the practical effect for 2026 is the same: the rules changed recently enough that a lease template from even a year ago is likely out of step with what's actually required now.
The Moratorium With a Small-Owner Exception
Tacoma also bars evictions during two windows: a cold-weather period running November 1 through April 1, and a school-year window for any household that includes a child, student, or educator. Owners of four or fewer rental housing units in the city are exempted from both moratoriums, which covers a meaningful share of the self-managing owners in Tacoma who hold one house or a duplex rather than a portfolio.
A Few Questions Worth Settling Before Your Next Notice
Does any of this apply to a rental in Key Peninsula or unincorporated Pierce County? No. The Rental Housing Code and Landlord Fairness Code apply only inside Tacoma city limits. HB 1217's statewide cap and 90-day notice still apply anywhere in Washington subject to RCW 59.18, but the license requirement, the 5 percent relocation trigger, and the eviction moratoriums are specific to Tacoma.
Is relocation assistance automatic once I cross 5 percent? No. It's owed only if the tenant requests it after receiving the increase notice and then decides to relocate instead of paying the new rent.
What happens if my business license lapses mid-tenancy? Under the Rental Housing Code, an inactive license blocks both eviction and any further rent increase until it's reinstated, even against a tenant who has stopped paying rent.
None of this is legal advice, and the specific forms and thresholds above can change again as the city and state continue adjusting the rules. The pattern underneath them is durable, though. Tacoma's compliance load doesn't announce itself the way an annual percentage does. It sits quietly in municipal code until an eviction or a lease renewal forces the paperwork open. For owners managing a Tacoma rental without tracking city ordinance changes line by line, Gig Harbor Property Management keeps current lease documents, notice forms, and license status on file so a routine rent increase doesn't turn into a courtroom surprise. Schedule a Free Owner Consultation to have your lease and notice paperwork checked against the rules currently in effect.
