How the caps are calculated
California. 5% plus the percentage change in the CPI-U for the metro area where the unit is — April to April, or March to March where the Bureau of Labor Statistics does not publish April (Riverside–San Bernardino and San Diego) — rounded to a tenth of a point, never above 10%. Increases taking effect before August 1 use the previous year’s pair; from August 1, the current year’s. Counties outside the four metro areas use the California CPI of the Department of Industrial Relations. Example: $2,000 in Los Angeles with notice handed over on October 15, 2026 → up to $2,174.00 (8.7%), starting November 14, 2026. Details and the history by county: how much can a landlord raise rent in California.
Oregon and Washington. Both use 7% plus inflation, capped at 10%, and publish the number for each calendar year — Oregon’s Office of Economic Analysis from the West-region CPI by September 30, Washington’s Department of Commerce from the Seattle CPI in July. The calculator uses the published percentage for the year the increase takes effect. Oregon requires 90 days’ written notice (3 more if mailed), allows one increase every 12 months and none in the first year of a tenancy (ORS 90.323); spaces in manufactured-dwelling parks follow ORS 90.600 instead, with a 6% cap in facilities of more than 30 spaces (ORS 90.324(1)(a)). Washington also bars any increase in the first 12 months of a tenancy and before a lease term ends, and requires its statutory notice form (RCW 59.18.720), which the PDF reproduces.
New York City. Rent-stabilized renewals follow the Rent Guidelines Board order in force on the date the new lease starts; the landlord must offer the renewal 90 to 150 days before the lease ends. The NYC building report checks whether a building appears on the rent-stabilized list and pulls its HPD registration and open violations.
How much notice for a rent increase in other states
The calculator does not compute a cap for these states. Where the rule comes from the state’s own statute site, this is the notice period we have on file — 16 states. Cities and counties can have their own rent control or notice rules.

Frequently asked questions
How much can a landlord raise rent in California?
Under Civil Code §1947.12, at most 5% plus the regional change in the cost of living, and never more than 10%, over any 12 months — counted from the lowest rent charged in the previous 12 months. For increases taking effect August 1, 2026 to July 31, 2027 that is 8.7% in Los Angeles and Orange counties; 8.1% in Riverside and San Bernardino counties; 8.2% in San Diego County; 8.8% in Alameda, Contra Costa, Marin, San Francisco and San Mateo counties; 8.6% in the other 48 counties. Units built in the last 15 years, some single-family homes and condos owned by individuals, and units under a stricter local rent control are exempt.
How much notice does a landlord have to give to raise rent?
California: 30 days if the increase (with any others in the last 12 months) is 10% or less, 90 days if more (Civil Code §827(b)), plus 5 days if the notice is mailed (CCP §1013); during a fixed-term lease, not before the term ends unless the lease allows it. Oregon: 90 days’ written notice, plus 3 if mailed, and never in the first year of the tenancy (ORS 90.323, 90.155). Washington: 90 days, and not before the lease term ends (RCW 59.18.140). New York: 30, 60 or 90 days for an increase of 5% or more, depending on how long the tenant has lived there or the lease term. Other states: see the table below — 16 of them have a rule we cite from the official statute.
How often can a landlord increase rent?
In California, no more than twice in 12 months and within the cap in total (§1947.12(a)(2)). In Washington, once every 12 months, never in the first 12 months of a tenancy, and not before the lease term ends (RCW 59.18.700, 59.18.140). In Oregon, once in any 12-month period and never during the first year of the tenancy (ORS 90.323(2)). In New York City, the Rent Guidelines Board notes that no increase is allowed while a lease is in effect.
What is the NYC rent increase for 2026–2027?
For rent-stabilized apartments, Rent Guidelines Board Order #58 sets 0% for one-year and 0% for two-year renewal leases commencing October 1, 2026 through September 30, 2027 (Order #57: 3% and 4.5% for leases that started in the year before). For market-rate apartments covered by the Good Cause Eviction Law, an increase above the local rent standard — 8.38% as of May 4, 2026 — can be found unreasonable.
Is this legal advice?
No. The calculator applies the statute and the official numbers cited in each result to the dates and amounts you enter. Local rent control, subsidized-housing rules and your lease can change the answer; check the cited source or talk to a lawyer or tenant help line.
Not legal advice. City and county rent control ordinances can limit increases more than state law — the California Attorney General’s landlord-tenant page explains the statewide rules. Data are checked monthly against the official sources.
