Key Requirements

  • ->2026 RSO rent cap: 4% (or banking if applicable)
  • ->30-day written notice required (60 days if using CPI adjustment)
  • ->Can only increase rent once per 12-month period
  • ->Banking of unused increases is allowed
  • ->Increase cannot be retaliatory or discriminatory
  • ->Must provide proper notice format (specific LAHD language required)

Step-by-Step Process

Step 1: Calculate Legal Amount

Current rent × 1.04 = maximum legal new rent. Example: $2,000 × 1.04 = $2,080

Step 2: Check Last Increase

Confirm it has been 12 months since the last increase. Cannot increase more than once per year.

Step 3: Draft Notice

Use LAHD form or legally compliant language. Must include: current rent, new rent, effective date, and citation to RSO.

Step 4: Serve Notice

Personally deliver or mail certified mail (proof of service required). Notice must be in tenant's preferred language if requested.

Step 5: Effective Date

Increase takes effect 30 days after notice is served. If increase is 10% or more, 60-day notice may be required.

Common Mistakes

Mistake 1: Increasing rent more than 4% — illegal; entire increase can be challenged

Mistake 2: Not waiting 12 months between increases — RSO caps frequency

Mistake 3: Using wrong notice format — notice must contain specific RSO language

Mistake 4: Not providing bilingual notice when tenant requests — violates LA law

Mistake 5: Increasing rent as retaliation for complaints — illegal; tenant can sue for damages

Mistake 6: Claiming the 10% threshold for 60-day notice when cap is only 4%
