Your street-cleaning sign says 9–11am. The tickets say 9:14am.
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 matched roughly 659,000 SFMTA street-cleaning citations to the blocks where they were issued. The finding: that posted 2-hour window is mostly a 22-minute reality. On a typical block, nearly all tickets land in the same ~22-minute span right after sweeping starts — 87% within the first 45 minutes.
Take 214–255 Steiner St. Posted window: 9–11am. Over two years: 203 tickets, earliest at 9:00am sharp, the median ticket at 9:14am, and 90% already written by 9:39am. 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"
THE SCALE OF IT
- $105 street-cleaning fine in 2026
- 23.8M total parking citations in SF since 2008
- ~1.2M street-cleaning tickets in the last two years alone
- Enforcement is surging where the city is building: Mission Bay +107%, Financial District / South Beach +68% 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 data collection.
Reliability fixes:
- Fixed "locate me" not working on the first try. Tapping the location button now finds you right away — even the very first time you allow location access.
- More reliable sweep-alert setup.
Thanks for the early feedback. The posted sign is always the final authority.
