When to send a rent increase letter
A rent increase letter should be sent well before the increase takes effect. The most common timing is at lease renewal — when a fixed-term lease is about to expire and you're offering a new lease at a higher rate. For month-to-month tenancies, you can raise rent at any time with proper notice.
Good reasons to raise rent include rising property taxes, increased maintenance costs, market rate adjustments, and property improvements. Whatever the reason, giving tenants adequate notice and a clear explanation helps maintain a positive relationship.
Required notice periods by state
Notice requirements vary significantly by state:
- 30 days — the minimum in most states for month-to-month tenancies (e.g., Texas, Florida, Ohio)
- 60 days — required in states like California (for increases over 10%), Washington, and Oregon
- 90 days — required in some jurisdictions for large increases or when local rent control ordinances apply
For fixed-term leases, the rent increase typically takes effect at renewal. Include the new rent amount in the lease renewal letter or offer a new lease at the updated rate.
Rent-controlled cities (New York City, San Francisco, Los Angeles, and others) have their own rules that override state law, often requiring specific forms, filing with a rent board, and strict percentage caps.
How much should you increase rent?
There's no one-size-fits-all answer, but here are general guidelines:
- 2% to 3% — a modest increase that generally keeps pace with inflation and is unlikely to cause tenant turnover
- 3% to 5% — a moderate increase that's reasonable when justified by market conditions or property improvements
- 5% to 10% — a significant increase that should be accompanied by clear justification (major renovations, substantial market movement)
- Over 10% — large increases risk losing good tenants, and in some states, trigger additional notice requirements or are prohibited entirely
Research comparable rents in your area before deciding on an amount. A rent increase that prices your unit above market rate will lead to vacancies, which cost more than a modest increase would generate.
What to include in a rent increase letter
A professional rent increase letter should contain:
- Date of the letter — establishes when notice was given
- Tenant's name and property address — identifies the specific tenancy
- Current rent amount — confirms what the tenant is paying now
- New rent amount — clearly states the new monthly rent
- Effective date — when the new rent takes effect (must be after the required notice period)
- Reason for the increase — not always legally required, but helps maintain goodwill (rising taxes, market adjustment, property improvements)
- Updated payment instructions — if anything about payment has changed
- Landlord's contact information — a way for the tenant to reach you with questions
- Landlord's signature — sign and date the letter
Maintaining tenant relationships
How you communicate a rent increase matters as much as the amount. Good tenants who pay on time, maintain the property, and cause no issues are valuable — turnover is expensive. Here's how to handle the conversation well:
- Give more notice than required — 60 or 90 days gives tenants time to budget, even if your state only requires 30
- Explain the reason — tenants are more accepting when they understand why (property taxes went up, insurance increased, you made improvements)
- Highlight improvements — if you've upgraded appliances, repainted, or improved common areas, remind tenants of the value they're receiving
- Keep it professional — use a formal letter, not a text message or casual email
- Be open to discussion — for long-term tenants, consider a smaller increase or a longer lease in exchange for a commitment
- Offer a renewal incentive — a smaller increase for tenants who sign a longer lease benefits both parties with stability
Rent increase letter vs. lease renewal
A rent increase letter and a lease renewal are different documents, though they often go together. A rent increase letter simply notifies the tenant that the rent is going up. A lease renewal is a new lease agreement (or an amendment to the existing one) that includes the updated terms.
For month-to-month tenancies, a rent increase letter is sufficient — no new lease is required. For fixed-term leases, you'll typically send a renewal offer that includes the new rent amount along with any other updated terms.
