If comparable units advertise lower, or the notice period does not match local rules, you have a specific, factual question to put in writing.
Several cities restrict algorithmic rent-setting and litigation continues; local rules on notice periods and increases vary and are worth checking before you respond.
The protocol
- Photograph the notice and write down the date you received it.
- Record the notice period your local rules require.
- Collect the building's advertised rents for comparable units weekly for two weeks.
- Write to the manager asking how the increase was set and what alternatives exist.
- Decide your response — negotiate, accept with a fixed term, or plan to move — and record it.
