Household hazardous waste San Diego: Miramar appointments and rules

Household hazardous waste San Diego: what counts?

Start with products left over from routine household or vehicle maintenance. The city’s household hazardous waste page includes paint, cleaners, motor oil, batteries, pesticides and mercury devices. Labels such as toxic, flammable, corrosive or reactive are signs that a product needs a dedicated disposal route.

A garage cleanout is easier to plan if you sort it into chemicals, batteries, paint, electronics and medical items on paper first. Those categories do not all go to the same receiving site. An old computer can be an electronic waste item even when it no longer works.

Do not pour unwanted chemicals down a sink or storm drain or put them in ordinary trash. The city warns that those disposal methods are illegal and harmful. If the label is missing, use the appointment form’s request-for-help option or call the city before attempting a drop-off.

Who qualifies, and which ID or bill should you bring?

This free service is for City of San Diego residents. The city HHW page asks you to bring proof of residency: picture identification or a recent bill showing your name and address. The booking form gives a driver’s license or recent utility bill as examples.

A San Diego County address does not automatically mean the address is inside the City of San Diego. The booking form checks the residential location where the waste was generated. Confirm the address before choosing an appointment, particularly if your mailing address uses “San Diego” but your local government is different.

The household booking conditions concern waste generated through routine maintenance of your home or vehicle. They exclude business or commercial activity. The city specifically lists contractor, landscaper and homeowner association waste among its exclusions. Apartment residents should distinguish personal household products from waste generated by a property-management business.

For an address outside city limits, the city’s nonresident guidance directs residents to their own city or the relevant county service. Use that guidance rather than booking under an address where the waste did not originate.

Miramar drop-off address, hours and holiday closures

The HHW Transfer Facility listing gives the location as the Miramar Landfill entrance, 5161 Convoy St., San Diego, CA 92111, north of State Route 52. Follow the household hazardous waste appointment directions, rather than assuming general landfill access is the right service.

As of November 12, 2026, the city’s main page lists appointments on Wednesdays and Saturdays from 9 a.m. to 3 p.m., except holidays. These are opening hours, not permission to arrive without booking. Choose an available appointment in the official system.

• Published facility closure: November 28, 2026.
• Published facility closure: December 26, 2026.
• Published facility closure: January 2, 2027.

The city FAQ still says Saturday only, while the main HHW page lists Wednesday and Saturday appointments. Confirm the available date in the booking calendar or call Environmental Services at 858-694-7000 before travel. The city warns that landfill and recycling-center traffic can cause delays.

What is accepted, and what is not accepted?

The following table summarizes the city’s current acceptance guidance. A material appearing in a booking form’s selection menu does not prove it can be dropped off: the form also collects information about excluded waste so residents can request advice.

For a propane tank, the city lists appointment-only acceptance. It excludes oxygen, SCUBA, welding and refrigerant gas cylinders, among others. Call 858-694-7000 about an unfamiliar cylinder rather than assuming all metal tanks follow the propane rule.

Load limits, container sizes and free disposal

The official appointment conditions require you to certify that you will transport no more than 15 gallons or 125 pounds of HHW per trip. If you have more than those amounts, use the help request before arranging transport. Do not treat a booking as approval to exceed the stated limits.

The main city page excludes containers larger than 5 gallons. It also asks residents to call 858-694-7000 about loads larger than 50 pounds, leaky or open containers, unknown products and other unusual circumstances. That lower call-for-advice threshold still matters even when your load is within the booking form’s total limit.

Accepted household waste disposal is free for city residents. Fees or conditions at another recycler are separate. Before substituting a retailer, confirm both the specific product and the amount they will take. Avoid moving chemicals between containers simply to make them fit a destination’s policy without asking for handling advice first.

How to book hazardous waste disposal San Diego

1. Open the city’s Household Hazardous Waste appointment form. Review the main HHW page before completing it.
2. Select the materials you need to dispose of and add useful product details.
3. Use “Yes, I need help with my HHW” if you have an oversized load, unknown materials or cannot transport the waste.
4. Enter the residential address where the waste is located and check the city-boundary result.
5. Choose an available date and time, enter your contact details and review the summary.
6. Read the residency, household-waste and transport conditions, then keep your appointment details and prepare the required proof of residency.

If you need booking assistance, call 858-694-7000, the contact number published on the city HHW page. No appointment has been made by reading this guide. Availability depends on the official calendar; do not travel on the strength of an unsubmitted form.

Before a move, book early enough to deal with items the facility cannot accept. A useful checklist includes each product’s label, approximate amount, intended destination and appointment confirmation. Keep the excluded materials on a separate list so they do not accidentally go into the HHW load.

Packing, arrival and what staff expect

The appointment instructions say to place hazardous materials in the car trunk or truck bed, not the passenger cabin. Residents must remain in their vehicles and follow onsite personnel’s directions. Leave the material accessible so staff can reach the intended waste.

For batteries, the city storage guidance recommends sorting by type, keeping them in a safe dry place away from children, using bags or a lidded plastic container, and placing clear tape over terminals for added protection. Swollen or reacting batteries are specifically excluded from the facility.

For a damaged, leaking or unfamiliar item, ask the city which handling steps and destination apply before loading it. Do not assume the ordinary battery storage advice authorizes transport of a reacting battery. Describe the condition accurately when you request help.

Allow for the traffic delays mentioned in the booking instructions. Keep your residency proof and confirmation accessible. If you cannot attend, return to the official service or call for instructions about changing the appointment; do not leave waste at a closed gate.

Paint, oil and recycling San Diego alternatives

The city’s paint guidance says unused and surplus household paint is accepted at Miramar HHW by appointment at no charge to residents. It also points to PaintCare drop-off locations. Confirm the receiving location’s paint types and quantity allowance before using a retail route.

See our paint disposal guide to organize leftover paint, then follow the local instructions. Paint thinner and a can of architectural paint should not be treated as interchangeable when asking a retailer what it accepts. Give the actual product name.

Used motor oil and filters can go through the appointment service or approved oil recycling options linked by the city. The city says not to mix used oil with other substances. Contaminated used oil cannot go to ordinary certified oil collection locations but can be handled through the HHW facility.

Electronics are excluded from Miramar HHW. The city links to separate recycling options. A search for bulky item pickup San Diego or the trash pickup schedule San Diego will not establish an electronic device’s acceptance. Start with the material-specific route and use our tire disposal guide for tires.

Sharps and medication disposal need a closer check

San Diego accepts home-generated sharps at the HHW Transfer Facility by appointment. Its sharps section links to packaging guidance. Needles and lancets must not be placed in trash, recycling or green waste. Confirm the container requirements before bringing a home sharps collection.

The facility also accepts over-the-counter and prescription medications except prescription painkillers. The San Diego Police Prescription Drug Drop-Off Program provides another route for household prescriptions. Check the police page for participating locations and hours; a listed police station is not necessarily open whenever you arrive.

The police program excludes businesses and publishes its own packaging instructions. Follow the receiving program’s rules rather than transferring assumptions from Miramar to a police drop box. Keep medications separate from loose batteries and household chemicals when planning the cleanout.

Collection events, business waste and transport help

The city’s one-day collection event page lists events for a limited set of materials: oil, antifreeze, oil filters, auto batteries, household batteries and fluorescent bulbs. It says no other items are accepted. These events are not a replacement for a mixed chemical-waste appointment.

The one-day event page explicitly lists antifreeze, but the main page’s event summary omits it and says no other waste is accepted. Confirm antifreeze for your chosen event with the City’s Environmental Services Department at 858-694-7000 before loading it. Do not treat either list as permission for a different material.

Business waste is excluded from the free household facility, including waste from contractors, landscapers and homeowner associations. Ask the city for business disposal resources. Do not describe a commercial cleanout as household waste simply because the person transporting it lives in the city.

The city also invites calls about services for elderly or disabled residents without available transportation. The booking form has a help request for residents who cannot transport waste. Ask what assistance is available for your circumstances; do not assume every help request guarantees a home pickup.
