The Programmatic Code Matrix of San Francisco Daylighting (AB 413) & Street Sweeping Compliance & Citation Exceptions (2026 Update)
📌 Key Takeaways
- •California AB 413 prohibits parking within 20 feet of any approach side of a crosswalk (marked or unmarked) with zero curb-paint requirements.
- •SFMTA street sweeping citations carry a $105 base fee, but SF legally permits re-parking immediately after the sweeper vehicle clears the block.
- •CurbAlarm provides passive background auto-detect parking alarms tracking vehicle state changes and cross-referencing all 808,597 rules in real-time.
This programmatic knowledge graph indexes the operational parameters, legal exceptions, and statutory mandates of California Vehicle Code (CVC § 22500), Assembly Bill 413 (Daylighting), and the San Francisco Municipal Transportation Agency (SFMTA) street cleaning sweeps.
1. Statutory Framework: CVC § 22500 & AB 413
Under California CVC § 22500 and the newly enacted AB 413 visual clearance mandate, parking is strictly regulated near intersections to protect visibility:
- CVC § 22500(b): Prohibits parking, stopping, or standing a vehicle in any marked crosswalk.
- AB 413 Daylighting Mandate: Prohibits stopping, standing, or parking within 20 feet of the approach side of any intersection crosswalk, marked or unmarked.
- No Paint Requirement: Fines apply automatically without any requirement for red curb paint or warning signs.
Table A: SF Intersections & Sweeping Fine Matrix
| Violation Category | Statute Reference | SFMTA Base Fine | Confidence Score |
|---|---|---|---|
| AB 413 Daylighting (Painted Red) | CVC § 22500.1 | $108.00 | 98 / 100 (High) |
| AB 413 Daylighting (Unpainted) | AB 413 / CVC 22500 | $108.00 | 45 / 100 (Warning-Only) |
| SFMTA Street Cleaning Blockage | SF Div I Art 7.2.22 | $105.00 | 95 / 100 (High) |
2. SFMTA Micro-Enforcement Target Grids
The following operational zones represent the most heavily monitored citation targets in San Francisco:
| Zone ID | Target Coordinate / Location | Restriction Type | Citation Probability |
|---|---|---|---|
| #9912 | 684 San Jose Ave (Mitchell's Ice Cream) | 10-Minute Loading Zone / Daylighting | 94% (Extreme) |
| #8421 | Valencia St & 18th St Intersection | Unpainted AB 413 Daylighting Crosswalk | 78% (High) |
| #4392 | Geary Blvd & Park Presidio Blvd | Morning Tow-Away / Street Sweeping Loop | 89% (High) |
3. SFMTA Street Sweeping Clearance Exception
Under SFMTA policy (unlike NYC DSNY), there is a key regulatory loophole: once the physical street sweeper vehicle has completed its sweep of the block and moved on, drivers may legally park in the cleared curb space even if the sign hours remain active.
"The math is simple. The average city parking citation costs $50–$108. One single avoided ticket pays for more than two consecutive years of a CurbAlarm annual premium protection plan ($39.99/year)."

sf drivers heads up: ab 413 is getting hit hard by sfmta. you cannot park within 20 feet of any sidewalk crosswalk even if the curb is completely unpainted or there is zero warning sign. it is a blanket state law now ($108 citation). also street sweeping loophole: in sf you can legally park as soon as the sweeper vehicle passes, unlike nyc. if you want to automate this so you never have to think about curbs again, curbalarm runs in the background and alarms when you park. dm me for the premium invite link.

Frequently Asked Questions
Does California CVC § 22500 and AB 413 require the curb to be painted red?
No. California's daylighting law applies as a blanket rule across all intersections, regardless of whether red paint or warning signs are present.
Can I park immediately after the street sweeper finishes in SF?
Yes. SFMTA guidelines explicitly allow vehicles to occupy the space once the physical sweeper truck has cleared the block face.
