Washington + Oregon rent-increase tools

Check a rent increase before it costs you.

Renters can see whether a notice follows the rules. Landlords can calculate the allowed amount and date, then create the paperwork to serve it correctly. Every answer links to an official source.

Included landlord review

The notice comes first. RentCap can flag other common paperwork risks too.

The optional review keeps adjacent deposit, move-out, fee, and entry issues from being confused with the core rent-increase result.

Notice and delivery

A legal amount can still be served the wrong way.

Using the wrong cap year, starting too soon, omitting required facts, or choosing an unsupported delivery path can require a corrected notice and a new wait.

RCW 59.18.700 · ORS 90.323

Deposit records

Move-in paperwork determines what can be defended later.

RentCap can flag missing condition checklists, deposit-account notices, and local documentation before those omissions reach move-out.

RCW 59.18.260 · PCC 30.01.087

Move-out accounting

A deduction needs a deadline, a reason, and a record.

The optional review checks the refund or statement date, itemization, supporting documents, and Portland-specific inspection duties.

RCW 59.18.280 · ORS 90.300 · PCC 30.01.087

The extra review is optional and does not change the rent-increase calculation. RentCap is self-help software, not a law firm.

Checked against current publications

Trust the source, not a stale summary.

RentCap records the publication used for every calculation and keeps a dated log when a cap, form, delivery rule, or city requirement changes.
