How much can a landlord raise rent?
In most states, a landlord can raise rent on a market-rate unit by any amount once the lease allows it, as long as the right notice is given and the increase isn’t retaliatory or discriminatory. The limits that do exist come from five places: the lease itself, state notice statutes, statewide caps, local rent control and subsidy program rules.
California, Oregon and Washington cap annual increases statewide on most covered units. Our landlord tenant law guide lays out those formulas and the 2026 maximums, so this page focuses on notice, timing and what an increase is worth when you sell.
A fixed-term lease keeps the rent the same for the whole term unless it has an escalation clause. So increases usually happen at renewal or, for month-to-month tenants, once the notice period runs.
Rent increase notice periods by state
Rent increase notice periods range from 30 to 90 days in the states below, and several states scale the notice to the size of the increase or how long the tenant has lived there. Always count from the date the tenant actually receives the notice. Add time if you send it by mail.
| State | Notice required | Statute |
|---|---|---|
| California | 30 days if the increase is 10% or less of the lowest rent charged in the past 12 months; 90 days if more than 10% (month-to-month and shorter tenancies) | Civil Code 827 |
| Oregon | 90 days, no increase in the first year, no more than once in 12 months (week-to-week: 7 days) | ORS 90.323 |
| Washington | 90 days; can’t take effect before the current term ends; 30 days for income-based subsidized rent | RCW 59.18.140 |
| New York | For increases of 5% or more: 30 days if under 1 year of occupancy, 60 days for 1 to 2 years, 90 days for 2 years or more | Real Property Law 226-c |
| Colorado | 60 days for tenancies with no written agreement; no more than one increase in any 12 months | C.R.S. 38-12-701, 38-12-702 |
| Nevada | 60 days; 30 days for periodic tenancies shorter than a month | NRS 118A.300 |
| Delaware | 60 days before the lease expires, stating the new rent and effective date | 25 Del. C. 5107 |
When a rent increase can take effect
A rent increase can take effect only after the full notice period runs and, for a fixed-term lease, usually not before the term ends. Washington says so directly in RCW 59.18.140, and most leases say the same thing.
Track increases over a rolling 12 months. California’s 10% test for the 90-day notice adds up every increase in the 12 months before the new rent starts, so two 6% raises in one year need the longer notice. Colorado and Oregon go further and allow only one increase in any 12-month period.
The consequences of getting it wrong are costly. In New York, if you miss the 226-c deadline, the tenancy continues on the old terms until the required notice period has run from the date you actually gave notice.
What a rent increase notice should include
A rent increase notice should state the current rent, the new rent and the exact date the new rent starts, and it should be delivered in a way you can prove. Some states require more. Oregon’s notice must show the dollar increase, the new rent, the effective date and, if the raise is above the cap, the facts supporting an exemption. In New York, the 226-c notice must also carry the information required under the 2024 Good Cause Eviction Law.
- Tenant names and the unit address exactly as they appear on the lease.
- Current monthly rent and new monthly rent, with the dollar and percentage change.
- The effective date, counted from the required notice period plus any mailing time.
- Any changes to other charges, such as parking, pet rent or utility billbacks.
- Any statement your state or city requires, such as a cap exemption or a rent control registration number.
- How it was served, with a dated proof of service kept in the unit file.
Rent caps and rent control: what limits the amount
Statewide caps limit the amount of an increase in California, Oregon and Washington, and local rent control can be stricter. Each law has exemptions, often for newer buildings; Oregon’s cap, for example, doesn’t apply to units whose first certificate of occupancy was issued less than 15 years before the notice.
New York took a different path. Where its Good Cause Eviction Law applies, mainly New York City and towns that opt in, an increase above the local rent standard is presumed unreasonable. That standard is the lower of an inflation index or 10%, and small landlords, defined as owning no more than 10 units in the state unless a locality sets a different number, are exempt.
Where none of these laws apply, the market sets the limit. Push rents too far and your best tenants move out, and the vacancy and turnover can cost more than the increase would have brought in.
Retaliation rules for rent increases
A landlord can’t raise rent to punish a tenant for complaining about repairs, contacting a code inspector or joining a tenant group. Most states protect that conduct, and several presume retaliation when an increase follows soon after it.
The windows differ. In California, Civil Code 1942.5 bars raising rent in retaliation within 180 days of protected activity, with punitive damages of $100 to $2,000 per retaliatory act in cases of fraud, oppression or malice. Texas Property Code 92.331 uses six months. New York Real Property Law 223-b presumes retaliation for an unreasonable increase within one year of a good-faith complaint.
The best defense is a routine you actually follow. If every renewal is priced from the same market survey and sent on the same schedule, an increase to a tenant who complained looks like what it is: the same increase everyone else got.
| State | Window | Statute |
|---|---|---|
| California | 180 days after protected activity | Civil Code 1942.5 |
| Texas | 6 months after protected activity | Property Code 92.331 |
| New York | 1-year presumption for unreasonable increases | Real Property Law 223-b |
Worked example: raising rents to market on a 20-unit building
Raising below-market rents to market adds NOI, and NOI divided by the cap rate is roughly what the building is worth. Take a 20-unit building where in-place rent averages $1,550 and comparable units lease for $1,725. The $175 gap, called loss-to-lease, adds up to $42,000 a year, about 10.1% of the $414,000 market rent roll.
Each tenant’s increase is about 11.3%. In California that’s above the 10% line in Civil Code 827, so month-to-month tenants would need 90 days’ notice, and the statewide cap would likely block it anyway. In New York the notice would be 30, 60 or 90 days depending on how long each tenant has lived there.
Assume no cap applies and you bring every unit to market at renewal. Management fees at 6% take $2,520 of the new rent, so NOI rises by $39,480. At a 6.0% cap rate, that’s about $658,000 of added value. If two tenants leave and each unit sits vacant for a month and needs $1,500 of turnover work, the one-time cost is $6,450.
If a cap held this year’s increase to 8%, rents would rise to $1,674. That adds $29,760 of gross rent and about $466,240 of value at the same cap rate, and the remaining $51 a unit stays on the table for a future year or a future owner.
| Item | To market (no cap) | 8% cap |
|---|---|---|
| New average rent | $1,725 | $1,674 |
| Added gross rent per year | $42,000 | $29,760 |
| Less 6% management fee | $2,520 | $1,786 |
| Added NOI | $39,480 | $27,974 |
| Added value at a 6.0% cap rate | $658,000 | $466,240 |
How buyers look at loss-to-lease
Buyers pay for the NOI a building earns today and treat loss-to-lease as upside they have to work for. Our glossary entry on loss-to-lease at /glossary/loss-to-lease/ explains how it’s measured on a rent roll.
A buyer will check whether the gap can actually be closed: lease expirations, caps, rent control status and whether the market rents in your pro forma are real. A seller who raises rents six to twelve months before listing, with proper notice, shows the higher income in the trailing 12 months instead of asking a buyer to believe it.
Raising rents right before a sale has costs, though. Fresh increases can push up turnover, and a buyer will notice if the new rents came with a spike in move-outs or concessions.
Rent increases in a 5+ unit apartment building
In a building with five or more units, rent increases are a calendar, not a one-off letter. Track every lease expiration, the last increase date and amount, the 12-month total and the notice deadline for each unit, so no notice goes out short or too often.
Space out renewals so a sudden market dip doesn’t hit every unit at once, and price each one from a current survey of comparable units. Keep copies of every notice and proof of service, because a buyer’s due diligence and tenant estoppel certificates will compare stated rents against what tenants were told.
