Direct Answer: Most permitted California demolition and remodel projects must divert at least 65% of debris from the landfill and prove it with weighed receipts from the facilities that took the material.
The shed is down. The old bathroom is gutted, the driveway is swept, and the pile that sat there for a week is finally gone. Then the building inspector asks where the material went, and asks to see it in writing.
That is the moment a lot of homeowners around Hollister, Gilroy, and out toward Salinas and Monterey County find out that building debris removal has two parts: hauling it away, and documenting it. Only one of those parts happens on the truck.
I have watched people scramble for receipts weeks after a tear-out because nobody mentioned the requirement at permit intake. So this article covers what the paperwork is made of, how sorting your pile decides whether you hit the diversion number, and why the same visual pile can weigh out very differently on the scale.
Why Building Debris Removal Is Only Half of a Permit Closeout
California’s green building code, CALGreen (Title 24, Part 11), requires most permitted construction, alteration, and demolition projects to keep at least 65% of nonhazardous debris out of the landfill. That is not a suggestion from the hauler. It is written into the code your permit was issued under, and you can read the state’s own explanation of the requirement and the compliance methods in CalRecycle’s construction and demolition diversion material.
So the question at final inspection is not “is the site clean.” It is “can you show where the material went.”
That means the job has two finish lines:
- Removed: the debris is off the property and the site passes a visual check.
- Documented: you hold receipts and tickets that tie tonnage to facilities and to your project address.
Here is where it bites people. A neighbor with a truck, a swap of loads into a friend’s bin, or a pile that vanishes without a scale ticket all leave you with a clean site and nothing to hand the inspector.
I have had callers in Gilroy tell me their contractor “took care of it,” then find out the debris went out in unmarked loads with no paper behind them. Rebuilding that trail after the fact is close to impossible. It is far easier to decide on day one that every load gets a ticket.
What the Debris Paper Trail Is Actually Made Of
Strip away the code language and the paperwork is three pieces.
- A plan submitted with the permit. Before work starts, you say roughly how much debris the job will make and which facilities or recyclers will take it.
- Weighed receipts or tickets. Every load that leaves gets a record from the place that received it, with weight or volume and the material type.
- A final tally tied to the project address. At the end you total it up and show the percentage that got diverted.
The forms and thresholds are handled locally, which is why two neighbors ten miles apart can get slightly different asks.
For a Gilroy job, confirm the exact forms with the City of Gilroy Building Division at 7351 Rosanna Street, open Monday through Thursday, 8:30 a.m. to 4:30 p.m. Gilroy also publishes a Builder’s Reuse and Recycling Guide that lists reuse and recycling firms, which makes filling out the plan much less of a guessing game.
Hollister and unincorporated San Benito County projects run through the county permit desk instead, and the request can look a little different there.
My honest advice: make that call before demo day, not after. Ten minutes at intake beats a stalled closeout, and it tells you exactly which tickets to keep from the first load forward. If you want the wider picture on debris handling, our Hollister and Gilroy construction trash removal guide walks through the practical side.

Sorted Loads vs. Mixed Loads: Where the 65% Is Won or Lost
This is the part that decides whether you clear the diversion number, and it happens before the truck shows up.
When materials are kept apart, each one can be routed to a facility that actually recycles it and reports it. Clean wood, metal, concrete, dirt, and unpainted drywall all have real recycling paths on the Central Coast.
One mixed pile is a different animal. A jumbled load has to go to a processing facility that can sort it and report a diversion percentage, and whatever that facility’s rate happens to be is the number you inherit.
A few honest limits worth knowing:
- Painted or stained wood scraps generally count as garbage, not recycled wood.
- General jobsite trash, food wrappers, tape, foam, and mixed packaging usually count as garbage too.
- Treated wood and any suspected asbestos material sit outside what a hauling crew handles at all. Those go through county hazardous waste programs, not our trucks.
I bring that last point up early on demolition walkthroughs, because people assume one truck solves everything. It does not, and finding out mid-job costs you a day.
If you are curious what happens to the sorted material after pickup, we broke that down in where construction debris actually goes after a remodel.
Where Common Tear-Out Materials Land
This is the general pattern I see on local jobs. Always confirm with the receiving facility, since what they accept can change.
| Material | Typical Destination | Counts Toward Diversion? |
|---|---|---|
| Clean untreated lumber and framing | Wood recycler or grinding facility | Usually yes, with a weight ticket |
| Scrap metal, appliances, rebar | Metal recycler | Yes, and metal has real scrap value |
| Concrete, brick, asphalt, dirt | Inert recycling or fill site | Yes, and heavy loads move the percentage fast |
| Unpainted drywall scrap | Facility that accepts gypsum | Often yes, confirm the site takes it |
| Painted or stained wood, trim | Landfill as garbage | Generally no |
| Mixed jobsite trash in one pile | Mixed C&D processing facility | Only at whatever rate that facility reports |
| Treated wood, suspected asbestos material | County hazardous waste program | Not handled by a hauling crew |
The Order That Keeps a Permit From Stalling
Five steps, in the order that actually saves you a headache at final inspection.

How Sorting Changes the Bill, Not Just the Paperwork
Disposal for construction and demolition material is normally charged by weight for tonnage loads and by volume for smaller trailer loads. That single fact explains most of the surprise on a disposal bill.
A half-full pickup of broken concrete or old roofing behaves nothing like a half-full pickup of cabinets and framing. One is dense and priced on the scale. The other is bulky and priced on the space it eats up in the truck.
So separating heavy inert material from light bulky debris before pickup can change two things at once:
- The disposal category the load falls into.
- The total, because inert material often has a cheaper, separate destination than mixed garbage.
I will not name a number here, because pile size, material mix, access, and stairs all move it. A walkthrough or a few clear photos gets you an accurate figure instead of a guess you have to renegotiate later. We wrote about that gap in why a junk removal quote and the final bill do not always match.
There is also a local reason to expect diversion rules and disposal costs to tighten rather than loosen. A proposal to expand the John Smith Road Landfill east of Hollister from roughly 95 acres to nearly 500 acres was rejected by the county Planning Commission in early 2024, and the operator later withdrew its appeal.
That leaves the site with limited remaining capacity while the county works out longer term plans. When landfill space in San Benito County is the constraint, keeping receipts and sorting loads stops feeling like paperwork and starts looking like the cheaper way to work.
The One Question to Ask Before You Book Anyone
Underneath all of this is a simpler worry I hear on the phone constantly. People are not really afraid of code sections. They are afraid of a surprise number and of being left holding a compliance problem after the truck drives off.
One customer put the fix better than I could: “The service provided was excellent! They disclosed all information upfront and there were no hidden fees.” – Jennifer L.
Upfront disclosure beats a low verbal estimate every time you have a permit riding on the outcome.
So before booking any crew for a permitted tear-out, ask two things:
- Can you give me disposal receipts for every load?
- Which facility is the load going to?
A crew that works locally will answer both without hesitating, because they already know the scale houses and the county programs. A vague answer is your signal to keep calling. If you are still deciding between a bin in the driveway and a crew doing the loading, dumpster rental versus full-service junk removal covers the tradeoffs, and who handles the debris after a demolition project covers who owns the responsibility.
Frequently Asked Questions About Debris Documentation
Does every remodel need a debris diversion plan?
Not every one. It depends on the permit type and the local threshold, which is exactly why you confirm at intake. In Gilroy that is the Building Division on Rosanna Street, and in Hollister it runs through the San Benito County permit desk. Small unpermitted projects generally are not affected, but if a permit is involved, ask.
Can I use my curbside bulky item pickup for demolition debris?
No. Programs like the Recology South Valley bulky item service in Gilroy are built for household items such as couches and mattresses, not construction and demolition material. And they will not give you the kind of weighed ticket a permit closeout wants.
What if I already hauled loads without keeping receipts?
Talk to the permit desk before you assume the worst. Sometimes there is a path using facility records or an alternate compliance method, but it is on you to chase it down. Start keeping tickets from the very next load, even if the earlier ones are gone.
I think there is asbestos in the old flooring. Can you still haul the rest?
Suspected asbestos material and treated wood are outside what our crews handle. Those go through county hazardous waste programs and the appropriate licensed specialists. We can talk through the rest of the pile once that material has been dealt with separately.
Is it worth sorting a small pile, or is that only for big jobs?
Even one load benefits. Pulling scrap metal and clean concrete out of a mixed pile can change the disposal category and give you two clean tickets instead of one vague one. On a single bathroom gut, that is maybe twenty minutes of sorting.
Have Questions About a Specific Tear-Out or Debris Pile?
Documented, sorted debris removal is routine work for a crew that runs demolition and large cleanouts across San Benito County, South Santa Clara County, and out toward Salinas and Monterey County, and that knows the John Smith Road Landfill and the local waste programs firsthand rather than dispatching from somewhere else. If you are trying to figure out how a particular pile should be split up or what receipts you should be collecting, questions like that are easy to answer by phone at (831) 297-1972.
