How to dispose of construction and remodel debris in Marin

What counts as construction and demolition (C&D) debris

C&D debris is the waste generated by building, renovating, or demolishing a structure. In practice, that means: drywall and plaster; flooring (tile, hardwood, laminate, carpet and pad); cabinets, countertops, and shelving; concrete, brick, and masonry; framing lumber and dimensional wood; roofing shingles; windows and doors; plumbing and electrical fixtures; and insulation. The key rule is this: if it came out of a wall, floor, ceiling, or fixture as part of a remodel or teardown, it's C&D debris — not household junk — and your curbside provider won't take it. Most service agreements between Marin garbage haulers and the county explicitly exclude C&D waste from the residential service terms.

Sort first — it lowers your disposal fees significantly

At Marin's transfer stations, sorted 'clean' loads are charged at lower rates than mixed debris. It's worth separating at the job site rather than mixing everything into one pile. The three categories that typically get better rates when kept separate: Clean wood (untreated dimensional lumber, plywood, and framing — not painted, stained, or pressure-treated), Clean drywall / gypsum board (unpainted or minimally painted, not wet or moldy), and Concrete and masonry (clean slabs, bricks, and block without significant rebar or mixed debris). Each of these can sometimes be diverted to recyclers or accepted at a lower landfill rate. Mixed C&D — where everything is thrown together, especially with tile, carpet, and fixtures — is heavier, harder to process, and charged accordingly. Keeping your clean wood pile separate from your tile and carpet pile before you start hauling is one of the easiest ways to reduce costs. Confirm current accepted materials and rates with Marin Recycling in San Rafael or Redwood Landfill in Novato before you load the truck — facilities periodically update their C&D categories.

Asbestos and lead paint: older Marin homes need an extra check

This is the step many Marin homeowners skip — and it's the most consequential one. Asbestos was used in many building materials until the late 1970s and into the 1980s: floor tiles (especially 9×9-inch vinyl tiles), the mastic adhesive underneath them, popcorn ceiling texture, pipe and duct insulation, and certain types of roof shingles all commonly contained asbestos in California homes built before about 1985. Marin's housing stock skews older — many homes in San Anselmo, Fairfax, Kentfield, and Ross were built in the 1950s and 60s — so asbestos-containing materials are common. You cannot legally haul asbestos-suspect debris to a standard transfer station without proper testing and abatement. If you're tearing out old floor tiles, popcorn ceilings, or pipe insulation in a pre-1985 home, get a certified asbestos inspector to test samples before the debris moves. Lead paint (present in virtually all pre-1978 homes) is a separate concern: the paint itself doesn't necessarily change the disposal route for debris, but sanding, cutting, or disturbing lead-painted surfaces creates dust that requires protective measures under EPA's Renovation, Repair, and Painting (RRP) rule for contractors. If you're doing the work yourself in your own home, you're not bound by the contractor rule, but wearing a respirator and using wet-cutting methods when cutting through old painted surfaces is a reasonable precaution.

Where to take C&D debris in Marin

The two main disposal destinations for Marin homeowners are Marin Recycling & Resource Recovery Center off Andersen Drive in San Rafael (the county's central facility) and Redwood Landfill in Novato, which handles north-county loads and accepts a wider range of heavy materials including concrete. Both charge for C&D debris by weight, with rates that vary by material type — call ahead to confirm current fees and what they're accepting before you drive over. For small volumes (a few contractor bags of tile from a bathroom floor), some residents use their regular garbage service's occasional large-item allowance, though most providers draw the line before accepting C&D bags. For a self-haul trip, you'll need a truck with a reliable tailgate or tie-down system; loose debris on the freeway is a hazard and a liability. Most facilities require all loads to be covered or tarped.

Dumpster rental vs. hauler vs. self-haul — which makes sense for your project

The right route depends on your timeline and volume. Self-haul works if you have a truck, modest volume (a bathroom or small kitchen), and the time to make one or two trips. The savings are real, but the logistics add up: sorting materials, making separate trips for different categories, learning each facility's rules, and tarping and unloading in a transfer station bay. Dumpster rental is well-suited to projects where debris accumulates over multiple days — a full kitchen gut, a room addition, or a deck replacement. You load at your pace, the rental company hauls it when you're done, and you only pay for the bin. The tradeoff: you're responsible for not putting banned materials in (asbestos, refrigerants, hazardous waste) and for keeping it covered so it doesn't become a neighborhood eyesore. A junk-removal crew makes the most sense when the debris is already piled up and you want it gone in one appointment, when the job involves items a dumpster can't handle well (an old built-in, a sink with residual plumbing connections, an old water heater), or when a hillside or narrow-staircase lot makes a dumpster placement impractical. In Mill Valley, Sausalito, and Fairfax — where many lots have no flat parking-pad space for a dumpster — a crew that carries and loads is often the only viable option.

What your contractor typically covers — and what they don't

This varies by contractor and contract, so check explicitly. Many GCs include debris removal in their bid, but sub-trade contractors (plumbers, electricians, tile setters, cabinet installers) often remove only their own packaging and cutoffs, leaving the larger debris pile for the homeowner to handle. Specialty trades like window installers and roofers usually take their old-material debris with them; flooring and tile contractors are more variable. Before a remodel starts, confirm in writing what your contractor will remove and what stays on site. If demolition debris is the homeowner's responsibility, it's better to know on day one than to find a pile of old drywall and cabinets waiting for you after the crew leaves.
