About LandlordKit

LandlordKit is built and run by Jake Sabbah, an independent landlord with a day job — the exact person these tools are for. It started as a set of spreadsheets for tracking the rules that actually bite small landlords (deposit deadlines, late-fee caps, filing dates) and became a public site when the "free" alternatives kept turning out to be ad farms, lead-capture walls, or simply wrong about state law.

The one rule everything here follows

We never publish a legal value we haven't verified. Every rule on this site cites its statute, links the source where available, and shows the date we last checked it. Where we haven't verified something yet, the site says so instead of guessing — you'll see "not yet verified" labels and confidence badges rather than confident-sounding filler. Laws change quietly (Florida's termination notice changed in 2023; Washington's rent-increase rules changed in 2025 — many sites still have both wrong), which is why the verification date matters as much as the value.

How it stays free

Every calculator and generator is free, without signup, forever — they run in your browser, so your numbers never touch a server. The site is paid for by LandlordKit Pro, a convenience layer for people with multiple units (saved details, batch documents, deadline reminders). No ads, no selling your data, no affiliate links dressed up as advice.
