Strip It To The Studs.
Leave The Block Alone.
Interior demolition, garage teardowns for ADUs and documented C&D recycling in El Cerrito · done clean on small lots, narrow streets and pre-1978 houses fifteen feet from the neighbor’s window.
Nobody Here Is Tearing
The Whole House Down
El Cerrito is expensive, dense and effectively built out. Lots are small, streets are narrow, and the houses · from the flats along the Ohlone Greenway and the San Pablo Avenue corridor up to the hillside streets above Arlington Boulevard · are worth far too much to knock over. So people don’t. They remodel, add on, and build ADUs.
That changes what demolition means here. Our El Cerrito work is overwhelmingly selective: take out the kitchen and two bathrooms, drop the ceilings, pull the flooring, remove the non-bearing walls, leave the structure and the neighbors intact. Or take down the 1940s single-car garage so an ADU can go in its place.
Two other things shape every job here. Age · this housing stock is overwhelmingly pre-1978, which puts nearly every remodel inside EPA Lead RRP territory and makes the acoustic ceiling, the duct wrap and the vinyl under the vinyl suspect until tested. And attitude · this is a sustainability-minded city, and nobody here is impressed by a roll-off of mixed debris headed to a landfill. So we sort, weigh, receipt and hand you the report.

Demolition Doesn’t.
This distinction costs El Cerrito homeowners real money when a contractor gets it backwards.
EPA’s Lead Renovation, Repair and Painting rule does not apply to demolition of an entire free-standing building. It does apply to renovation that modifies portions of a pre-1978 structure. Interior demolition is renovation. Taking out a 1952 kitchen here is exactly the activity the rule was written for.
- Containment first. Plastic, zip walls, negative pressure where warranted, floor protection on every path to the door.
- Suspect materials tested, not assumed. Acoustic ceiling material, acoustic plaster and HVAC ducting get tested if they’re being disturbed.
- Wood, glass, rubber and metal need no asbestos testing. Everything else on a pre-1978 remodel gets a second look.
- Abatement stays with abatement contractors. Asbestos work of 100 sq ft or more needs certification plus Cal/OSHA registration and 24 hours’ notice.
If your project removes a load-supporting structural member · even a partial demolition, even a garage · the BAAQMD notification is required regardless of asbestos content, age or size. Ten working days’ notice, reducible to 72 hours for dwellings of four units or fewer with an added fee. The start date you file is a confirmed date, not a guess. Full teardown instead? →
65% Isn’t A Goal. It’s The Floor.
California’s statewide minimum diversion of non-hazardous C&D waste is 65%. Claiming it is easy. Proving it at closeout is where projects stall.
Waste Management Plan
Most Contra Costa jurisdictions want an approved plan on file before the permit issues · materials, volumes, facilities. Filing late is a common reason a small remodel permit sits.
Waste Management Report
The closeout version, backed by receipts: facility name, date, place of origin, material type and quantity. In unincorporated Contra Costa these move through Green Halo as of August 4, 2025.
What’s In, What’s Out
Concrete, wood, metal, drywall and mixed C&D count. Excavated soil and land-clearing debris are excluded · a detail that trips up plenty of contractors on their first report.
Portals, deposits and form names vary by city · unincorporated Contra Costa and Oakland run C&D documentation through Green Halo, others use their own forms or a refundable recycling deposit. We confirm the City of El Cerrito’s current C&D process, thresholds and any deposit before we quote, so the number you get already includes the reporting work. The statewide 65% floor applies either way. Permit guide →
Working Clean When The House Next Door Is Fifteen Feet Away
On an El Cerrito lot there’s no staging area and no buffer. The job runs in public. We run it accordingly.
Neighbor Notification Before Day One
We knock, leave a card with the schedule and a phone number, and say which days are loud. In a city this dense, a neighbor who knows what’s happening is the cheapest insurance there is.
Dust Control, Not Dust Hope
Interior containment with plastic and zip walls, wet methods on cutting, HEPA vacuums for cleanup, misting on anything airborne outside.
Street And Sidewalk Protection
Plywood on the sidewalk, plates over the gutter line, storm drain inlets protected before anything is broken.
Equipment Doesn’t Camp
On narrow El Cerrito streets a roll-off parked for a week is a genuine problem, so we schedule hauls tight instead of leaving a box in front of somebody’s house.
Broom-Clean Every Evening
Debris out, nails swept, path clear, plastic re-sealed. Then a closeout package: permit records, weight tickets, the waste management report and photos.
What Selective Demolition Runs
Working ranges for the jobs we do most here. Your written estimate is fixed after the site walk · these are planning numbers.
| Job | Typical Range | What Moves The Number |
|---|---|---|
| Interior demolition | $2 to $8 / sq ft | Trades, occupancy, containment |
| Kitchen strip-out | $1,500 to $3,000 | Cabinets, tile, subfloor layers |
| Bathroom strip-out | $1,000 to $2,500 | Mud-set tile, cast iron tub, second floor |
| Detached garage | $2,500 to $6,500 | Slab, access width, roofing |
| Slab / foundation removal | $2 to $5 / sq ft | Thickness, rebar, depth |
| Concrete removal | $3 to $8 / sq ft | Rebar +$1-$3/sq ft; dump $90-$160/ton |
| Driveway, 200-600 sq ft | $1,200 to $4,500 | Slope, curb cut, tonnage |
| Lead-safe practices, pre-1978 | $3 to $8 / sq ft | Area disturbed, containment |
| Asbestos abatement, if triggered | $5 to $15 / sq ft | Material, friability, containment |
| Asbestos testing | $300 to $900 | Samples and material types |
Old houses here are layered. Under the laminate there’s vinyl, under that a second vinyl, under that the original subfloor · and the adhesive between them is a classic asbestos-suspect material. We test before we quote, so it’s a line item at estimate time instead of a stop-work order on day two. Bay Area cost guide →

El Cerrito is twelve minutes from our yard in El Sobrante.
See All Service AreasWhat El Cerrito Clients Say
Whole-house strip-out on a 1949 place with neighbors ten feet off both sides. They notified everyone before day one, kept the plastic up and swept the sidewalk nightly. Not one complaint.
I’m a GC and I use them because the diversion paperwork actually shows up. Weight tickets, facility names, quantities · straight into the closeout file. Saves me a week of chasing.
Our old garage came down for the ADU and the slab went with it. Two days, no damage to the fence, everything hauled the same trip instead of a bin sitting on our street.
El Cerrito Demolition Questions
My El Cerrito house is from the 1950s. Does lead law apply to my remodel?
Almost certainly yes. EPA’s Lead RRP rule applies to renovation that modifies portions of a pre-1978 structure, and El Cerrito’s housing stock is overwhelmingly pre-1978. Interior demolition is renovation, so lead-safe practices, containment and verification cleaning apply. The one place the rule does not apply is demolition of an entire free-standing building · the opposite of what most people assume. How we run interior demolition →
How do I prove the 65% recycling requirement at permit closeout?
With receipts, not an estimate · facility name, date, place of origin, material type and quantity per load. Most jurisdictions here also want an approved Waste Management Plan before the permit issues and the Waste Management Report after completion. Unincorporated Contra Costa runs both through Green Halo as of August 4, 2025. Forms differ by city, so we confirm El Cerrito’s current process before quoting and build the reporting into the price. Excavated soil and land-clearing debris are excluded from the calculation.
Can you work without shutting down my street?
That’s the standard here, and it’s why we plan the haul schedule before the demo schedule. We size trucks to what these streets can turn around, protect the sidewalk and gutter line, and cycle equipment in and out rather than parking a roll-off for a week. Where a closure or encroachment permit genuinely is required, we identify it at estimate time and pull it.
Do I need a permit to take down my garage for an ADU?
Yes. Garage demolition is permitted work, and because it removes load-supporting structural members it triggers the BAAQMD notification regardless of the building’s age, size or asbestos content · 10 working days ahead, reducible to 72 hours for dwellings of four or fewer units with an added fee. City requirements vary, so we confirm El Cerrito’s current submittal list and fees before quoting. ADU site prep →
Can we live in the house during an interior demolition?
Often, if the work is zoned. We can seal off a kitchen or bathroom wing and keep a bedroom and a working bath live. It costs more · containment, daily cleanup and restricted hours add time · and on a pre-1978 house with lead-safe practices in play, some phases aren’t compatible with people in the building. We’ll tell you which is which before you decide.
How much of the old house can we actually salvage?
More than most people expect, depending on what your schedule allows. Clear framing lumber, appliances, usable cabinets, fixtures, doors and hardwood flooring all come out by hand instead of by machine. Salvage is slower but cuts disposal tonnage and helps the diversion number. We price both so you can see what the deconstruction premium buys. Deconstruction vs. demolition →
