about your section 13 notice

The notice your landlord sent you is the starting point for any challenge. Let's check it's valid.

What is a Section 13 notice? It's the official form your landlord must use to propose a rent increase. It should be headed "Section 13 Notice" or reference "Form 4A." If your landlord just sent a letter or email saying the rent is going up, that may not be a valid notice.

date on the notice Please enter the date on your notice.

date the increase takes effect Please enter the date your increase takes effect.

did your landlord use the official form?
