Compliance

California Wants 65% of Your Construction Debris Diverted

The paperwork is now part of the job. If you cannot show where the debris went, the diversion did not happen as far as the permit is concerned.

The rule most contractors meet at permit stage

If you are pulling a building permit in California for anything substantial, there is a waste requirement attached to it that surprises people who have not built here recently.

Three separate obligations sitting in one sentence: a target, a plan filed up front, and evidence kept afterwards. Most people discover the third one last, which is the expensive order to discover it in.

Whether your particular project is "covered" depends on its type and scale and on how your jurisdiction implements the code, so confirm with whoever is issuing your permit. But if it is covered, the plan is part of the application rather than something you produce at the end.

What a waste management plan has to do

It is a short document, and the work is in being realistic rather than in being long.

Broadly it needs to set out what the project will generate, roughly how much of it, where each material stream is going, and how you will show it got there. A plan that says "debris will be recycled" is not a plan; one that says "concrete and asphalt to an inert facility, clean wood to a green waste processor, metal to a scrap yard, mixed residual to the county landfill" is.

The practical advice is to write it around the streams you can actually separate on the site you actually have. A plan that assumes four separate containers on a lot that fits one is a plan you will abandon in week two, and the receipts at the end will not match it.

Receipts are the compliance, not the intention

This is the part worth internalising.

The requirement is not that you meant to divert 65%. It is that you can demonstrate it. Applicants are required to maintain recycling receipts as proof, which means the tickets, weights and facility records are the compliance artefact.

What that means in practice on a job site:

• Keep every ticket, from the first load to the last. A missing ticket is a load that did not count.
• Make sure the tickets say what the load was. A weight with no material description proves tonnage, not diversion.
• Nominate one person to collect them. Tickets that live in six different trucks do not get assembled at the end.
• Photograph them as they arrive if the originals live in a glovebox for a month.

There is a related obligation worth knowing about: self-haulers, junk haulers and other removal service providers may be required to complete a self attestation form documenting that waste was properly collected, separated, recycled and transported to an authorised facility. If you are moving material yourself rather than using a hauler, that paperwork is yours.

What actually counts as diverted

Diversion means the material went somewhere other than landfill disposal. The streams that reliably count around here:

• Clean concrete, block, asphalt and masonry to an inert processing facility. This is usually the single biggest tonnage on a demolition job and the easiest win.
• Scrap metal to a scrap yard, which has positive value as well as counting.
• Clean untreated wood to a green waste or biomass processor.
• Cardboard and clean packaging, which new-build generates in enormous volume.
• Green waste and land clearing material to a compost or biomass facility.

Two local facilities worth knowing for the wood and green streams: Wood Industries on Avenue 296 in Visalia, and Tulare County Compost and Biomass on Road 140 in Tulare.

What does not count is a mixed container of everything going to the working face of a landfill. Some facilities sort mixed C&D and recover a percentage, and that recovery can count — but you need the facility's documentation of the recovery rate, not an assumption.

Why wood is the material that decides it

Here is the connection most people miss, and it is the reason the 65% target is more achievable than it sounds.

SB 1383's definition of organic waste expressly includes non-hazardous wood waste. That places construction lumber in the same regulatory category as food scraps and yard trimmings — which is why the same statute that put a green cart on your curb also put a diversion target on your framing offcuts.

On a typical framing or renovation job, wood is one of the largest streams by volume. Separate it and keep it clean and you are a long way toward the target before you have done anything clever. Bury it in a mixed container and you have thrown away your easiest tonnage.

Clean means clean: untreated, unpainted, no laminate, fasteners out where practical. Pressure-treated timber does not qualify and neither does anything with a finish on it, which rules out most exterior material and most demolition trim.

How to set a site up to hit 65%

• Decide the streams before the first container arrives. Retrofitting separation onto a site that has been mixing for three weeks does not work.
• Run a separate small container for concrete and masonry. Heaviest material, cheapest route, biggest single contribution to the percentage.
• Give clean wood its own container on any job with significant framing or demolition lumber.
• Set up a metal pile from day one. It pays for itself and it counts.
• Put a cardboard point by the trades' entrance and break everything down flat.
• Label the containers physically. A sheet of ply marked CLEAN WOOD ONLY is what actually protects a stream.
• Brief every trade on day one, and again when a new crew arrives. One subcontractor throwing drywall into the wood container contaminates the load and the ticket.
• Phase the containers to the trade sequence rather than leaving one box on site for the whole build.

What we can and cannot give you

Worth being straight about this, because some haulers are vaguer than they should be.

What we can do: deliver separated containers, take each stream to an appropriate facility, and give you the disposal tickets for every load with the material and the weight on them. If you tell us at booking that the job is under a diversion requirement, we will set the containers up around the streams rather than around convenience.

What we cannot do: certify your project's compliance. The permit obligation sits with the applicant, the plan is yours to file, and whether a given facility's handling counts as diversion in your jurisdiction is a question for whoever issued the permit. Anyone promising to guarantee your compliance is selling something they do not control.

We would rather tell you that clearly at booking than have you assume it at final inspection.

Getting the documentation right

• Confirm with your permit issuer whether your project is covered, before you start
• Write the plan around streams you can genuinely separate on your actual site
• Tell your hauler the job is under a diversion requirement at booking, not at the end
• Keep every ticket, and make sure each states the material as well as the weight
• Nominate one person to hold the file
• Photograph tickets as they arrive
• Ask any mixed-C&D facility for its documented recovery rate rather than assuming one
• If you self-haul any of it, find out whether a self attestation form applies to you
