Know your legal max. Serve the notice. Keep the receipts.
RentCeiling tells small landlords in rent-controlled U.S. jurisdictions the legal maximum rent increase for each unit, generates the statutorily-compliant tenant notice, and logs every calculation for audits or disputes.
Covers California · Oregon at launch — New York, DC, Saint Paul, Montgomery County, and Washington jurisdictions land next.
Why this exists
Three reasons small landlords get this wrong.
Caps change every year.
The CPI piece of AB 1482 is recomputed every August — last year's Google search will get you sued. Oregon recalculates against the West-Region CPI on the same cycle. The 2026 numbers are not the 2025 numbers.
Overshoot = treble damages.
Cal. Civ. Code §1947.12(h)(2) lets the tenant recover up to three times the overcharge plus attorney fees. Oregon ORS §90.323(5) is three months' rent plus damages and fees. One miscalculation can erase a year of NOI.
Your PMS won't compute it.
AppFolio, Buildium, Yardi, RealPage, Stessa, Baselane — none compute per-unit caps against jurisdiction-specific formulas. You're on your own. Until now.
Pricing
Free for one unit. $19/mo for everything else.
No surprises. Pricing is anchored to the $150–$300 a landlord-tenant law firm will charge to review one notice — pay us once and you get unlimited.
