The City of San Diego's Environmental Services division has refreshed its guidance on household hazardous waste disposal. This matters now, especially as spring renovation season peaks across the metro area. Many homeowners and contractors still assume paint cans, batteries, solvents, and old fluorescent bulbs can go into regular trash or dumpsters. They cannot.
Hazardous materials—including old pesticides, motor oil, antifreeze, aerosol cans, and electronics—leach into soil and groundwater. In East County, Lemon Grove, and the foothills, where water tables are shallow, that risk compounds fast. Storm drains in Santee and El Cajon don't filter. Every illegal dump uphill eventually flows downhill.
San Diego has free drop-off events and permanent collection sites. The city's updated materials spell out what qualifies as hazardous and where to take it. If you're a homeowner doing a bathroom remodel, a roofer replacing old flashings, or a landscaper removing old chemical storage—the responsibility is yours. Ignorance is not a legal defense.
Contractors and property managers should ask their waste hauler whether they accept hazardous material. Most don't. Do not assume a dumpster rental covers it. Verify in writing. Keep receipts. If you hire someone else to haul, you remain liable for where it ends up. That is the law and the ethics.
Clean streets and clean canyons start with clean disposal decisions made one job at a time. San Diego's updated guidance is free and accessible. Use it.
What to do with your next load
- Visit sandiego.gov/environmental-services to find your nearest hazardous waste drop-off location and upcoming collection events.
- Before starting a renovation or landscaping project, identify and segregate hazardous materials. Do not mix them with regular construction debris.
- Ask your waste hauler or contractor in writing whether they accept hazardous waste. If they say yes, ask for proof of proper disposal and keep the receipt.
- For batteries, electronics, paint, and chemicals: plan ahead. Many free events fill up quickly, especially in spring.
- If you find illegally dumped material in a canyon or wash, report it to the City of San Diego's Illegal Dumping Hotline, not social media.
