Free for one unit. $19/mo for everything else.
Pricing is anchored to the $150–$300 a landlord-tenant law firm will charge to review a single rent-increase notice. Pay us once for a month and you cover unlimited notices across up to 20 units, with an audit-ready compliance log attached to every calc.
No credit card needed to use the calculator. The $9 paid‑stamp flow is
deployed — clicking Pay $9 from any worksheet's
audit page drops you into Stripe Checkout (or, during the activation window, a
1‑click waitlist that converts to first‑in‑line live checkout).

Why $19/mo
The cost of a single missed cap dwarfs the cost of a year of Pro.
One attorney notice review: $150–$300.
Landlord-tenant firms in California and Oregon charge $150–$300 flat to review one rent-increase notice against the statute. Pro is $19/mo — $228/yr — for unlimited notices across your whole portfolio.
One overshot cap: up to 3× damages + fees.
Cal. Civ. Code §1947.12(h)(2) authorizes trebled damages plus attorney fees. Oregon ORS §90.323(5) is three months' rent plus damages and fees. A single arithmetic error on a $2,500/mo unit can run $7,500–$22,500 before the lawyer bill.
Zero additional risk for the annual CPI refresh.
The January CPI update is automatic and included. No surprise “data update” tier, no per-jurisdiction paywall, no paid upgrade when the 2027 numbers land.
Frequently asked
Pricing FAQ
Is the calculator really free? What's the catch?
No catch. The calculator is permanently free for one unit, no sign-up, no credit card. We make money on the notice PDF ($9 one-off) and Pro subscriptions ($19/mo) — both optional. If you only need the cap number and the formula, you never have to pay us a dollar.
Why is paid checkout behind an activation step?
The full Stripe Checkout code path is already deployed — create-session, 303-redirect, success page, HMAC-verified webhook, paid-record sidecar, PAID-watermarked archive PDF. What's still pending is a single factory-level secret-key provisioning step (Council-approved 2026-04-24 via session EkFciezwwdUIDbfFKmfh3). Until then, clicking Pay $9 from any worksheet takes you to a 1-click email-capture interstitial that activates the moment the key lands. Nobody gets charged before the flow is end-to-end verified.
What counts as a “unit” on the Pro plan?
One rentable address with one tenant ledger. A duplex is two units. A single-family house with a separate ADU rented to a different tenant is two units. A rooming-house with one lease per room is each room. If you're not sure, email and we'll figure it out — the 20-unit cap is a soft guideline, not a hard wall.
What happens if I need more than 20 units?
Pro stretches to 40–50 units in practice — we don't hard-cap, we just ask you to email before you exceed 20 so we can discuss fair pricing. The Legal Pro tier (multi-jurisdiction dashboard for attorneys serving 5+ landlord clients) is coming later in 2026 at $49/mo.
Do you offer annual billing or a discount?
Not yet. Monthly only at launch, at $19/mo. When we introduce annual billing the target discount is 2 months free (effectively $190/yr). Pro waitlist members get first access to the annual rate when it opens.
Do you offer refunds?
30-day full refund on Pro, no questions. Per-notice purchases are refundable if the PDF fails to render or if the calculation was wrong and you can't use the notice. Compliance software that couldn't stand behind its own math wouldn't be compliance software.
Is there an API?
Not in week 1. Multi-jurisdiction dashboard users on the future Legal Pro tier get read-only JSON access to the rule-set ($49/mo). Full write-API is a 2H-2026 roadmap item contingent on demand.
Get launch updates.
We'll email when notice generation goes live (Stripe flips on the same day) and when each new jurisdiction ships. RentCeiling currently covers eight: California, Los Angeles RSO, Oregon, New York City, Washington DC, Saint Paul, Montgomery County MD, and Washington State.
