Rent Increase Notice Requirements by State

Notice must be in writing

Nearly every state that specifies a notice period also requires it in writing. Oral notice of a rent increase is legally ineffective in most jurisdictions, and a written waiver of the notice requirement is often void as against public policy.

The clock starts when the tenant receives the notice, not when it is sent

Maryland and California are explicit: notice must be delivered by the statutory deadline, not just mailed. Certified mail with return receipt — or personal service — is the safest delivery practice in any state.

Email and text delivery may not satisfy statutory requirements

Most state statutes predate electronic communication and do not contemplate email. Only Connecticut and Maryland expressly allow electronic delivery, and only if the tenant has opted in. Assume first-class mail or personal service unless the lease and statute both specify otherwise.

A notice delivered mid-term does not take effect mid-term

A landlord cannot raise rent during a fixed-term lease without a contractual escalation clause. The increase is unenforceable until the term ends. Washington's RCW 59.18.140 makes this explicit; the same principle applies nationwide.

State preemption vs. local ordinances — always check both

Even in states that have no statewide notice requirement (Texas, Pennsylvania, Missouri), some cities impose their own rules. Conversely, statewide caps (California, Oregon, Washington) often exempt entire classes of units. Confirm both layers before relying on the cap as a defense or a limit.

California — AB 1482

Annual increases capped at 5% + local CPI, with a hard ceiling of 10%/year. Applies to most residential units 15+ years old; new construction, single-family homes (in most cases), and certain owner-occupied duplexes are exempt. Codified at Cal. Civ. Code §§ 1947.12 (cap) and 1946.2 (just cause).

Local rent control in San Francisco, Oakland, Los Angeles, Berkeley, and Santa Monica may be stricter than the statewide cap.

Oregon — ORS 90.323 / SB 611 (2023)

Annual increases capped at 7% + CPI West, with a hard ceiling of 10%/year. The 2026 maximum is 9.5%. Applies to units 15+ years old; new construction during the first 15 years is exempt. No rent increases are permitted in the first year of any tenancy.

Washington — HB 1217 (eff. May 7, 2025)

Annual increases capped at the lower of 7% + CPI or 10%/year. Manufactured home community lots are capped at 5%. Notice requirements expanded to 90 days statewide (30 days for subsidized housing). Codified at RCW 59.18.700 et seq.

Washington DC — Rent Stabilization

For rent-stabilized units (most pre-1976 buildings of 5+ units): annual increases capped at CPI + 2%, hard ceiling 10%/year. Elderly or disabled tenants face only CPI alone, capped at 5%. Codified at D.C. Code § 42-3502.08.

San Francisco, CA

Covers most buildings with 3+ units built before June 13, 1979. Annual increases limited to 60% of CPI. Just cause required for eviction. Operates under SF Rent Ordinance (Admin. Code Ch. 37) in addition to California AB 1482.

New York City, NY

Rent Stabilization covers ~1 million apartments (6+ unit buildings built before 1974 or receiving certain tax benefits). NYC Rent Guidelines Board sets annual allowable increases. The 2019 HSTPA dramatically restricted deregulation pathways.

Newark, NJ

City ordinance limits annual increases to 5% for covered units; 90-day notice required; covers most residential rentals with 4+ units. New Jersey has no statewide cap, making Newark's ordinance among the strongest local protections in the state.

Washington, DC

Comprehensive rent stabilization (D.C. Code § 42-3502) covers most pre-1976 buildings of 5+ units. Cap is CPI + 2% (max 10%); elderly or disabled tenants face only 2% (max 5%). DC Rental Housing Commission enforces.

Portland, OR

Oregon's statewide cap (ORS 90.323) supersedes earlier city rules, but Portland retains a relocation-assistance ordinance: landlords who raise rent more than 10% must pay moving costs to displaced tenants (City Code § 30.01.085).

How much notice does a landlord have to give before raising rent?

The required notice depends on your state. Most states require 30 to 60 days written notice for month-to-month tenancies, though some require longer for larger increases. California requires 30 days for increases of 10% or less and 90 days for increases above 10%. Washington and Oregon both require 90 days. Florida requires 30 days. Several states (Texas, Pennsylvania, Tennessee, and others) have no statewide notice requirement at all and rely on the lease terms. Always verify your state's current statute — see the table on this page for citations.

Can a landlord raise rent in the middle of a fixed-term lease?

Generally no. Across all 50 states, a landlord cannot increase rent during a fixed-term lease unless the lease itself contains a clause permitting it (such as a cost-of-living escalation). The rent agreed to at signing is the rent for the duration of the term. The landlord must wait until the term ends, then provide the statutory notice required by their state before any new increase can take effect.

Can a landlord raise rent without notice?

No. Every state that allows rent increases requires written notice before the increase takes effect, even when the state doesn't specify a minimum notice period — because the lease or month-to-month rental agreement itself sets the terms. A landlord who increases rent without any notice has effectively breached the rental agreement, and the increase is typically unenforceable until proper notice is given.

What should a rent increase notice include?

A complete rent increase notice should include: the tenant's name and rental address, the date the notice is delivered, the current rent amount, the new rent amount, the effective date of the increase, a reference to the section of the lease that authorizes the change (or the relevant state statute for month-to-month tenancies), the signature of the landlord or property manager, and the method of delivery (personal service, certified mail, etc.). Many states require specific language — check your state's statute or consult a landlord-tenant attorney before sending.

Does a rent increase notice have to be in writing?

Yes, in nearly every state. Most state statutes that govern rent increase notices require them to be in writing. Oral notice is legally ineffective in most jurisdictions and can leave the landlord unable to enforce the increase. The safest practice is written notice delivered by personal service, certified mail with return receipt, or any method explicitly specified by your state's statute or the lease.

Can a landlord raise rent during the first year of a lease?

In most states, yes — once the fixed term ends, the landlord can issue notice of an increase. Oregon is the major exception: ORS 90.323 explicitly prohibits rent increases during the first year of any tenancy. Several rent-controlled cities (San Francisco, Washington DC, parts of New York City) have similar first-year prohibitions. Verify your local rules before increasing rent in year one.

Is there a limit on how much rent can be raised?

Most states do not cap rent increases for properties that fall outside rent-stabilized programs. The exceptions are California (AB 1482: 5% + CPI, capped at 10%/year, for units 15+ years old), Oregon (ORS 90.323: 7% + CPI West, capped at 10%/year), Washington (HB 1217: 7% + CPI or 10%/year, whichever is lower), and Washington DC's rent stabilization (CPI + 2%, capped at 10%/year). New York City rent stabilization sets allowable annual increases through the Rent Guidelines Board. Some individual cities (e.g., Newark NJ at 5%) impose additional local caps.

What happens if the rent increase notice is invalid?

An improperly served or insufficient notice does not automatically void the tenant's obligation to pay — the existing rent remains in effect until a valid notice is given and the statutory waiting period has elapsed. If the landlord attempts to evict for non-payment of the increased amount based on a defective notice, courts will typically rule for the tenant. Cure the defect by serving a new, compliant notice and waiting the full statutory period before treating the new rent as due.

Can a rent increase notice be sent by email or text message?

Electronic delivery is allowed only in a small number of states (Connecticut, Maryland) and only if the tenant has expressly opted in. In every other state, most statutes were written before email was common and either require personal delivery or first-class mail. Even where electronic notice is technically permitted by statute, the lease may require a specific delivery method. The safest practice is written notice delivered by certified mail with return receipt or personal service, with a copy emailed as a courtesy.

Do federal fair housing rules apply to rent increases?

Yes. Even where a rent increase is otherwise lawful, it cannot be applied selectively against tenants in protected classes (race, color, religion, sex, national origin, disability, familial status). A rent increase imposed on one tenant but not similarly-situated tenants of a different protected class may give rise to a discrimination claim under the federal Fair Housing Act. Many states and cities also recognize additional protected classes (source of income, sexual orientation, age). Apply increases uniformly across the property.
