Sonoma's Trash & Recycling: The Rules That Matter

Every city handles trash & recycling a little differently. In Sonoma, California, there are 6 distinct rules that residents and property owners should be aware of. Some are stricter than what neighboring cities enforce, and others are more relaxed. Here is what you need to know.

Illegal Dumping

Dumping waste on public or private property in Sonoma is prosecuted under California Penal Code §374.3 with mandatory fines starting at $250 and rising to $10,000 for commercial-quantity third offenses; cleanup costs are recoverable from the dumper.

Key details: Governing statute: Cal. Penal Code §374.3. First-offense fine: $250–$1,000 (mandatory). Third-offense fine: $750–$3,000 (general); $6,000–$10,000 (commercial). Tire dumping: Fines doubled. Cleanup: Court must order cost recovery from dumper.

Cal. Penal Code §374.3 fines: $250–$1,000 (1st), $500–$1,500 (2nd), $750–$3,000 (3rd); doubled for tires; commercial-quantity dumping = misdemeanor up to 6 months jail + $1,000–$10,000. The court must order cleanup costs. The City may layer SMC Ch. 1.28 administrative fines ($100 / $200 / $500) and abate the dump site through SMC §14.30 with full cost-recovery and a property lien.

Compared to other cities, Sonoma takes a harder line on illegal dumping. The enforcement and penalty structure reflects that.

Bin Placement Rules

SMC 7.08.060 governs the location of solid-waste and source-separated containers; carts should be at the curb the night before pickup and may not be stored in view of the public street between collection days.

Key details: Code section: SMC 7.08.060 — container location. Set-out time: Night before scheduled collection day. Lid orientation: Opening toward the street. Clearance: 2-3 ft between carts; 3 ft from vehicles/obstacles. Storage location: On premises, not in public right-of-way between pickups.

Improperly placed or unattended carts left in the public right-of-way outside collection days can be cited as a nuisance under SMC 14.30 (Public Nuisances) and addressed via SMC Ch. 1.28 administrative citations ($100 / $200 / $500 escalating). Damaged or lost carts are billed at SGC replacement cost. Stored or visible carts in violation of architectural standards in the historic Plaza district can trigger Design Review enforcement.

Pickup Rules & Schedules

Solid waste collection in the City of Sonoma is provided exclusively by the franchised hauler (Sonoma Garbage Collectors) under SMC Chapter 7.08; every occupied premises must subscribe and use the three-cart system (gray trash, blue recycling, green organics) required by California SB 1383.

Key details: Exclusive franchised hauler: Sonoma Garbage Collectors (SMC 7.08.030). Mandatory subscription: Yes — every premises (SMC Ch. 7.08). Required carts: 3-cart system: trash, recycling (blue), organics (green). Pickup frequency: Weekly. Set-out timing: Night before collection day (carts out before dawn).

Failure to subscribe to mandatory service or to source-separate organics, recyclables, and trash is a violation of SMC Ch. 7.08/7.10 enforceable through the City's administrative citation program (SMC Ch. 1.28, added by Ord. 03-2018): typical fines are $100 first offense, $200 second within a year, and $500 each subsequent, with daily accrual. SB 1383 (14 CCR §18997.2) also authorizes the jurisdiction to impose tiered fines of up to $50/day (minor), $100/day (moderate), and $500/day (major) on non-compliant generators.

Bulk Item Disposal

Sonoma Garbage Collectors holds two free Spring/Fall cleanups (April and October) where SGC residential customers may set out one large item under 75 lbs plus up to ten bags; on-demand bulky pickup is also available for a fee at (707) 996-7555.

Key details: Free cleanup events: Spring (April) and Fall (October). Event allowance: 1 bulky item under 75 lbs + 10 bags. On-demand pickup: Available for a fee — call SGC (707) 996-7555. E-waste & mattresses: Handled separately (state law bans landfilling). Authority: SMC Ch. 7.08 (special collections).

Putting bulky items at the curb outside of a scheduled cleanup or appointment is a violation of SMC 7.08 (illegal placement of solid waste) and can be cited under SMC Ch. 1.28: $100 first, $200 second, $500 subsequent, plus cost-recovery for SGC's collection and disposal. Dumping a mattress or appliance on the street can also trigger Cal. Penal Code §374.3 (mandatory fines starting at $250 first conviction).

The rules around bulk item disposal in Sonoma lean permissive, but that does not mean anything goes.

Recycling Requirements

SMC Chapter 7.10 implements California SB 1383 (2016) and requires every residential and commercial generator in Sonoma to subscribe to recycling service and source-separate recyclables (blue cart) and organics (green cart) from trash.

Key details: Code section: SMC Ch. 7.10 — implements SB 1383. State authority: 14 CCR Div. 7, Ch. 12 (SB 1383); AB 341; AB 1826. Cart system: Blue = recycling; Green = organics; Gray = trash. Bio-plastics: NOT accepted in green cart. SB 1383 fines: Up to $500/day per 14 CCR §18997.2.

Beginning January 1, 2024 SB 1383 (14 CCR §18997.2) authorizes Sonoma to assess tiered fines against non-compliant generators: $50–$100/day for minor violations (e.g., contamination of carts), $100–$200/day for moderate violations, and $250–$500/day for major or repeat violations. Locally these are layered with SMC Ch. 1.28 administrative citations ($100 / $200 / $500). Persistent commercial non-compliance can also trigger CalRecycle enforcement against the City.

Compared to other cities, Sonoma takes a harder line on recycling requirements. The enforcement and penalty structure reflects that.

Yard Waste Collection

Sonoma supplies every residence with a 96-gallon green organics cart for grass, leaves, hedge clippings, branches, and untreated lumber; yard waste must go in the green cart under SMC Ch. 7.10 (SB 1383) and may not be burned because the City sits in a CAL FIRE State Responsibility Area / WUI.

Key details: Cart: 96-gallon green organics cart (mixed yard waste + food scraps). Accepted: Grass, leaves, hedge clippings, weeds, branches, untreated lumber, food scraps. Mandatory diversion: Yes — SMC Ch. 7.10 / SB 1383. Open burning: Prohibited (BAAQMD Reg. 5-401). Large-volume option: 20- or 30-yard SGC debris box by appointment.

Putting yard waste in the gray trash cart is a SB 1383 contamination violation, subject to SMC Ch. 7.10 enforcement and 14 CCR §18997.2 tiered fines ($50–$500/day depending on severity). Burning yard waste violates BAAQMD Regulation 5-401 (open burning), which carries civil penalties up to $1,000 per violation per day under Cal. Health & Safety Code §42402 (and significantly more for negligent or intentional violations), and during a Red Flag day can also trigger Cal. Penal Code §452 (reckless burning) charges. The City can issue SMC Ch. 1.28 administrative citations ($100 / $200 / $500) layered on top.
