Rent Increase Notice Mistakes That Can Create Problems

Rent increases fail when notice timing, amount, or delivery is wrong. Here is what to document before sending a rent increase notice.

Check lease type and local rules

Fixed-term leases often lock rent until renewal. Month-to-month tenancies typically need advance written notice — verify on our data page and with local rent control if applicable.

Calculate the new amount clearly

Use the rent increase calculator to show old rent, new rent, percentage change, and effective date. Tenants should not have to reverse-engineer the math.

Example: 60-day notice for month-to-month

Current rent $1,800. Notice dated April 1 with effective June 1 gives 60 days. Notice states new rent $1,890, delivery method, and where to send questions.

Common mistakes to avoid

• Effective date before the notice period ends.
• Increasing rent during a fixed lease without a valid clause.
• Not delivering notice to all tenants on the lease.
• Ignoring local rent cap or registration requirements.
