Understanding Rent Control Laws
States with Rent Control
Currently, California, Oregon, New York, New Jersey, and Washington DC have statewide rent control or stabilization laws. Several other states have cities with local rent control ordinances.
- California: 5% + CPI (max 10%)
- Oregon: 7% + CPI (max 10%)
- NYC: Rent Stabilization Board sets limits
Notice Requirements
Even in states without rent control, landlords must provide advance notice before raising rent. The required notice period varies by state, typically ranging from 15 to 90 days.
- Most states: 30 days notice
- Oregon: 90 days notice
- Some states: 60 days for longer tenancies
How this calculator works
Increase amount = proposed rent − current rent. Increase % = increase amount ÷ current rent × 100. If rent control applies: max allowed = current rent × min(state base + CPI, state cap) — 5% + CPI capped at 10% in California, 7% + CPI capped at 10% in Oregon.
Inputs
- Current and proposed rent — dollar change drives percent increase.
- State — sets rent control flag, max increase, and required notice days.
- CPI rate — used in CPI-plus-cap formulas (default 3% if not specified).
Assumptions
- Increase applies at renewal or with proper notice for month-to-month.
- Unit is subject to state rent control only where flagged—not local boards unless noted.
- Notice is delivered in writing within required lead time.
Limitations
- Local rent boards (NYC, SF, etc.) may set lower caps than state law.
- Just-cause eviction rules may limit increases on certain tenancies.
- Does not model preferential rent or subsidy program caps.
Example calculation
- California unit: current rent $2,000, proposed $2,250 (+12.5%), CPI left at the default 3%.
- AB 1482 cap: 5% + CPI, never more than 10% → 5% + 3% = 8%, so at most $160 a month more ($2,160).
- The $250 increase exceeds the $160 cap → non-compliant without exemption.
- Required notice: 90 days, because the increase is more than 10%. An increase of 10% or less needs 30 days.
Rent-controlled jurisdictions require both compliant amounts and proper written notice. Exempt properties (new construction, single-family in some cases) may follow different rules.
Common mistakes
Raising rent without required notice
Increases without 30–90 days' written notice may be void. Use a rent increase notice with proof of delivery.
Exceeding CPI-plus caps
States like California and Oregon limit annual increases even when market rent is higher.
Increasing during a fixed lease term
Mid-lease increases are generally prohibited unless the lease includes an escalation clause.
