San Marcos, CA Trash & Recycling: Dumpster Rules (2026)

030 requires refuse and recycling bins at commercial, industrial, public/institutional, mixed-use and multifamily sites to be enclosed on all four sides unless stored inside a legally approved building, with a swinging double-door access gate on one side that has locking cane bolts and closes itself. Enclosures larger than 10 by 14 feet need a separate walk-in pedestrian gate so staff are not forced to open the main dumpster gate for foot traffic. Walls must be solid masonry with a decorative finish matching the main building; split-face block is recommended and brick or tile veneer is discouraged.

No material may be stacked higher than the enclosure walls, and the pad underneath must be a level, reinforced concrete slab extending 48 inches in front of the gates, with raised bumper guards inside to stop the dumpster from hitting the walls. 445-1 sets the numbers: a 10-by-14-foot minimum enclosure footprint, 6-foot enclosure walls, 16 feet of overhead clearance, an 18-foot-wide driveway, a 36-foot turn-around radius where required, a 5-foot minimum building separation, and enclosures no farther than 150 feet from the main structure for commercial/industrial sites (250 feet from the unit entry for multifamily).

Setbacks are 5 feet from interior property lines for commercial/industrial (10 feet for multifamily) and 10 feet from any residential property line, and the enclosure must sit behind the main building's front setback. Enclosures cannot go in a required front setback, court, alley, or landscaped or parking area, and cannot sit closer to the public right-of-way than the main structure. 050.
