How much should you raise the rent at renewal? A calm DIY landlord’s workbook for caps, notice, and keeping good tenants

How much to raise rent on renewal depends on the rules for your unit, comparable local rents, and what losing a good tenant would cost. Check the lawful range and notice date first, then weigh a modest increase against an empty unit.

Your reliable tenant pays below nearby asking rents. Owners in this good-tenant discussion face the same choice: how much is fair without losing them?

This is not legal advice. Rent caps, exemptions, notice periods, delivery rules, and required forms vary by state and city; some change yearly. Check your local rules and lease, or ask a local attorney before sending notice.

How much should you raise rent at renewal?

Check the applicable rules, notice date, comparables, and turnover cost. Resolve uncertain exemptions before naming a new rent.

Step 1: Check whether a cap or local rule applies

Cap coverage can depend on building age, owner type, and required exemption notices. City or county rules may be stricter; a vacant listing's asking rent does not set your tenant's limit.

For example, California Civil Code §1947.12 limits covered increases over 12 months to 5% plus the percentage change in the cost of living, or 10%, whichever is lower, measured from the lowest gross rent charged in the preceding 12 months. It also limits the same tenant to two increases in that period. Exemptions include certain newer housing and some separately owned homes, but the latter requires specified written notice and other conditions; local limits can be tighter.

Washington RCW 59.18.700 bars increases during the first 12 months of a tenancy unless an exemption applies. After that, its cap is 7% plus CPI, or 10%, whichever is less, over a 12-month period, subject to exemptions. The Washington Department of Commerce's published 2026 figure is 9.683% for covered residential properties. Check your unit's rules.

Step 2: Confirm notice and your send-by date

Start with the effective date. Check your lease, tenancy type, increase size, occupancy length, local rule, and delivery method. Count backward for required notice and mail time; allow for any longer lease period. Calendar the send-by date and keep delivery proof. If you miss it, move the effective date.

For month-to-month or shorter residential tenancies, California Civil Code §827(b) requires at least 30 days for increases of 10% or less and 90 days for increases above 10%, considering other increases in the previous 12 months. Mailed notice is subject to additional service rules. Do not present these tiers as a statutory fixed-term renewal rule.

In Washington, RCW 59.18.140(3) generally requires at least 90 days' prior written notice, and the increase cannot take effect before the rental agreement term ends. Where no specific rent-increase notice statute applies, allowing at least as much time as it takes to end the tenancy is a cautious planning habit, not a universal legal rule. Owners' notice-and-exemption questions show why you need to check both before mailing.

Step 3: Know your market

Compare nearby listings by size, condition, amenities, and lease terms. Asking rent is not a signed rent. Adjust for differences and write down a realistic range, not just the highest listing. The gap is not an automatic target.

Step 4: Price the turnover

Add vacant days, cleaning, repairs, listing, screening, utilities, and your own time. Owners debating a longtime tenant's below-market rent face the same trade-off. Use your figures in the Cost of Empty Days worksheet.

Hypothetical, not a forecast: Rent is $1,800 a month. Compare a $100 monthly increase with $200. If the tenant stays, the larger raise adds $1,200 over 12 months compared with the smaller one. But 20 vacant days at the old rate cost about $1,200; add $600 for cleaning and advertising, and turnover costs about $1,800. That exceeds the first year's extra $1,200, before your time or the replacement tenant's actual rent. Replace these assumptions with your own.

Step 5: Choose a number and a path

Compare three paths within applicable caps and notice rules:

• Steady step: a modest raise you can explain with expenses and comps.

• Two-renewal path: a smaller step now; check the rules and market again before proposing another at the next renewal.

• Longer term: offer a longer lease at a stated rent if it works for both sides and local rules permit it.

If the tenant leaves, will replacement rent cover vacancy and work? If not, revisit the number.

Step 6: Send a clear, friendly written notice

State current rent, proposed rent, effective date, and how to respond. Explain briefly and respectfully. Deliver notice by the required method and retain proof. Some places require specific wording or a form; check before treating a friendly email as formal notice.

A human tone helps: “We appreciate how you've cared for the home. At renewal, we propose a new monthly rent of [amount] effective [date]. Please let us know if you'd like to discuss it.” This is a tone example, not a legal notice template.

If the tenant pushes back

Listen, re-check the rules and comparables, and consider a middle ground. Document revised terms and check whether fresh notice is needed. Avoid pressure tactics.

Test your numbers before sending

The free Rent Increase Planner works out a notice period and send-by date in California, New York, and Washington. In other supported states it uses a labeled cautious minimum, not a claimed rent-increase statute, or your longer lease notice requirement. It checks statewide caps in California and Washington only, suggests a range based on comps you enter, and weighs keeping a tenant against your vacancy and turnover assumptions. It cannot predict whether a tenant will leave.

Except in Washington, New York, and North Carolina, it can fill in a draft notice for you to review and send yourself; it does not send or track delivery. It does not check city or county rules. Try the free Rent Increase Planner as a planning aid, not a legal sign-off.

One last thing

A fair increase is one you can explain and deliver on time. Keep your comps, estimate, and notice record. This article and planner are educational, not legal advice; check state and city rules or ask a local attorney before acting.
