How this hub works
Each calculator above covers the states where the rule applies, independently, with its own cited statute. Where a state sets a fixed rule — a deadline, a cap, a notice period — we show it with the exact code section. Where the law leaves a point to the court or to the lease, we say so instead of inventing a number. See our methodology for how every figure is verified.
What's in this cluster
Renting raises a handful of related deadline and dollar questions, usually in a particular order. This cluster is built around those questions rather than as one generic "landlord-tenant calculator":
- Security deposits — the limit, the return deadline, interest where the law requires it, and the penalty for keeping one wrongly.
- Eviction — the notice that must come first and the legal timeline that follows, plus what happens to belongings left behind.
- Rent — the notice and any state cap on an increase, and the most a landlord can charge for late rent.
- Ending a tenancy — the notice that ends a lease, the cost of leaving early, relocation payments after a no-fault termination and repair-and-deduct rights, where states provide them.
Every calculator links back to this hub and to its closest sibling calculators, so an answer on one question leads naturally to the next question it usually raises.
Why state matters more than most people expect
Landlord-tenant law is set state by state, and the differences are concrete. On deposits, California requires an itemized statement within 21 calendar days after the tenant vacates (Cal. Civ. Code 1950.5(h)(1)) while Texas allows until the 30th day after the tenant surrenders the premises (Tex. Prop. Code 92.103(a)). On rent, California limits an increase over 12 months to 5% plus the change in the cost of living or 10%, whichever is lower (Cal. Civ. Code 1947.12), and Washington to 7% plus the consumer price index or 10%, whichever is less (RCW 59.18.700). One rule is federal: a service member may terminate a lease under the Servicemembers Civil Relief Act (50 U.S.C. 3955). A single national calculator averages all of that away, so this hub builds one calculator per question, with a dedicated page for every state where the rule applies.
Many cities add their own rules on top of state law, and those local rules are not modeled here; check your city's housing office as well.
