Check if your rent increase is legal before you agree to it
Some states and cities cap rent increases or require long written notice. Check the rules where you live, then push back in writing if the increase breaks them.
Part of: Is my rent increase legal? How to push back or negotiate
1. Copy this prompt
Paste it into ChatGPT, Claude, Gemini or Grok (the free versions work), then replace the [highlighted brackets] with your details. Leave out account numbers and SSNs.
My landlord is raising my rent from $[OLD RENT] to $[NEW RENT] starting [DATE]. I got the written notice on [DATE]. I live in [CITY, STATE] in a [apartment / house / condo] built around [YEAR, if known]. 1) Work out the percentage increase. 2) List what I should check on official sites for my state and city: rent caps, notice periods, how often rent can rise, and exemptions (for example, newer buildings). Don't state a rule as fact unless you're sure, and tell me where to verify it. 3) Draft a short, polite email asking my landlord to confirm the increase follows local rules, and a second version I can use if I've confirmed it breaks them.

What to expect, and what to do if they say no
What happened when people tried it
- We haven't verified a real-world example for this one yet, so it's a tool guide plus a prompt. Tried it? Tell us what happened (link below).
Why this works
The problem: Many tenants accept a rent increase without checking whether it's allowed. California and Oregon have statewide caps, some cities have rent control, and many places have notice rules.
How AI helps: AI can read your lease and the increase notice, list the questions to check (cap, notice period, how often rent can rise), and draft a polite written reply once you've confirmed the local rules on an official site.

Watch out for
- No verified AI-specific success story yet. This is a how-to guide built on official sources.
- Most US states don't cap rent increases at all. Notice rules still apply in many places.
- California's cap applies to most housing more than 15 years old; Oregon's cap doesn't apply to buildings whose first certificate of occupancy is less than 15 years old. Exemptions matter.
- AI tools can get local laws wrong. Confirm every rule on your state, city or county site, or with a local tenant group or legal aid.
