How to raise rent on a tenant

The letter is the last step, not the first.

Ask first

A rent conversation opened 90 days out is a renewal. The same number posted 30 days out is an ultimatum.

Raising rent is an operations problem with a legal wrapper. Get the number right, open the conversation early, and the notice becomes a formality rather than an event.

Setting a number you can defend

  1. 01Pull three genuinely comparable current listings — same bed count, same block, same condition.
  2. 02Adjust for what yours lacks: no parking, a walk-up, an older kitchen.
  3. 03Check the cap where one applies — 5% plus CPI, max 10%, in California (§ 1947.12, checked 2026-09-04).
  4. 04Price the downside in the turnover cost calculator.
  5. 05Choose the number you would still send if they said yes immediately.

The market is what re-lets, not what is listed

Listings show asking prices, including the ones that have sat for six weeks. If you can see days-on-market, weight the ones that went quickly.

The conversation before the letter

A tenant who hears the number in a friendly message, with a reason and an alternative, mostly accepts it. A tenant who finds it in an envelope mostly starts looking. The message is three sentences: costs went up, here is the new number from a date, here is a longer term at a smaller number if you prefer.

  • Say what changed — tax, insurance, the block.
  • Offer a choice between term and rate.
  • Give a reply-by date.
  • Do not negotiate against yourself before they answer.

The letter

Then send it properly: old rent, new rent, effective date, notice period, everything else unchanged. The rent increase letter template fills it in and prints. Serve it the way the lease says notices are served and keep proof.

When not to raise

  • When the tenant has just made a repair complaint — retaliation presumptions are unforgiving.
  • When you are inside a fixed term.
  • When the unit needs work you have not done; the raise invites the complaint.
  • When the raise is smaller than the turnover it risks — which is most raises under 3% on a good tenant.

The last one is arithmetic, not sentiment: run it, and let the turnover cost calculator answer.
