Auto-save where you park, and your car on the map: • New Shortcuts actions: Save Parking Spot and Clear Parking Spot. Run them when your car's CarPlay or Bluetooth disconnects and connects, and CURB saves the block you parked on and turns on its sweep alerts by itself. • Set it up in the ⓘ menu, Sweep alerts, Auto-save where you park. San Francisco for now. • The saved spot shows there too, with its next sweep, Show on map and Clear. • A little car sits on the curb where you parked. Tap that curb to pick yours: red car, pickup, van, taxi, convertible, sports car or surf wagon. • Share where I parked, on every curb: it sends the side, the next sweep and a link that opens the map with the car on it. Handy when you park someone else's car. • Zoomed out, both sides of a street now show as two lines, so you can tell them apart. • Now in 25 cities, from Oakland and Los Angeles to New York, Chicago, Toronto and Montréal. Zoom out and tap a city pin, or open Cities in the ⓘ menu. The posted sign is always the final authority.
Your street-cleaning sign says 9 to 11am. The tickets say 9:12am. CURB is a free map of San Francisco street-parking rules, and the only one that shows you WHEN tickets actually get written, not just when the sign says you're at risk. I obtained about 1.35 million GPS-located SFMTA street-cleaning citations through a public records request and matched over a million of them to the blocks where they were issued (2024 to mid 2026). The finding: that posted 2-hour window is mostly a 20-minute reality. On a typical block, most tickets land within about 20 minutes of each other. Citywide, about 77% are written in the first 45 minutes of the posted window and about 90% in the first hour. Take the 200 block of Steiner St. Posted window: 9 to 11am. From 2024 to mid 2026: 278 tickets, the earliest at 9:00am, the median at 9:12am, and 90% written by 9:21am. The "2 hours" was never real. WHAT CURB SHOWS YOU • Every block colored by its next street sweep. See at a glance where it's safe to park • When tickets actually get written on your block, rebuilt from public SFMTA citation data • Residential permit (RPP) zones, meters, and color curb • ~1,975 unmetered white passenger-loading zones (627 of them by schools) pulled straight from the city's own curb map, the ones DataSF leaves out • Holiday enforcement flags, like SF suspending daytime street-sweeping enforcement on Juneteenth MOVE-YOUR-CAR ALERTS • Pick how hard CURB nags you: a single 30-minute heads-up (Light), plus the night before (Normal), or add a morning-of warning too (Intense) • Choose the voice: warm and funny, drill-sergeant, or deadpan-with-the-receipts • Native iOS push, plus a one-tap calendar (.ics) sweep event • No more "I forgot it was Tuesday" MORE CITIES CURB now maps 24 more cities block by block, from each city's open data, with alerts before the rule starts: • Oakland, Berkeley, San Jose, Sacramento, Los Angeles, Unincorporated LA County, Santa Monica, Glendale, Riverside, San Diego, Denver, Saint Paul and Norfolk: street sweeping • New York City and Hoboken: alternate side parking • Philadelphia, Pittsburgh, Paterson, Washington DC and Montréal (in French or English): street cleaning • Chicago and Madison: street sweeping and winter rules • Milwaukee: night parking and winter rules • Toronto: winter parking Zoom out and tap a city pin, or open Cities in the ⓘ menu. THE SCALE OF IT • $105 street-cleaning fine in 2026 • 24M total parking citations in SF since 2008 • Over a million street-cleaning tickets since 2024 alone • Enforcement is surging where the city is building: Mission Bay and Financial District / South Beach are up the most vs. five years ago A NOTE ON HONESTY CURB reads the patterns in public data so you don't have to. But the posted physical sign is always the final authority. CURB never overrides it, and neither should you. Built by one person in San Francisco who got tired of the parking math. Free. No ads. No signup. No account. No cookies. If you turn on alerts, CURB stores an anonymous push token with the curb you picked.
