How to Prepare Your Home for Demolition Day in Southern California
Preparing your home for demolition day involves disconnecting utilities, clearing the work area, confirming permits, and coordinating access. Here's a complete checklist.
Step 1: Confirm Permits Are Issued
Before demolition can begin, your permit must be issued and posted on-site. In Southern California, this means a permit card from your city's building department visible at the property. C&S Demolition handles permit applications for all projects — we confirm permit issuance before scheduling your demo date.
Step 2: Disconnect and Cap Utilities
All utilities serving the demolition area must be disconnected before work begins. This includes:
- Electricity: Disconnected by your utility provider (SCE, LADWP, etc.) or a licensed electrician
- Natural gas: SoCal Gas must disconnect the service line at the meter
- Water: Main shutoff at the meter; plumber caps supply lines
- Sewer: Lines must be capped at or near the property line for full demolitions
Coordinate utility disconnects 2–3 weeks before your demo date — utility companies are often backlogged.

Step 3: Clear and Protect the Work Area
Remove all personal property from the demolition area. For interior demo, that means furniture, appliances, window treatments, and anything stored in walls or attic spaces. For exterior or full-home demo, all landscaping tools, vehicles, and storage items should be moved away from the structure.
Protect adjacent landscaping, HVAC equipment, or neighboring structures with temporary barriers if needed. C&S Demolition brings dust barriers and protective sheeting for interior demo projects.
Step 4: Notify Neighbors
Demolition generates noise, dust, and truck traffic. In Southern California, most cities require notice to adjacent property owners before major demolition work begins. Even where not legally required, notifying neighbors 3–5 days in advance avoids complaints and maintains relationships. Let them know start/end dates and daily work hours (typically 7 AM–4 PM in SoCal).
Step 5: Confirm Access and Parking
C&S Demolition crews arrive with trucks, equipment trailers, and debris hauling vehicles. Make sure the driveway and street access is clear. In tight neighborhoods, temporary no-parking zones may need to be coordinated with the city. We'll walk through access requirements during our pre-job site visit so nothing is a surprise on demo day.
Safety and Preparation Before Any Demolition Work
Demolition is hazardous work even when it looks simple. Before any teardown begins, utilities must be properly handled. Electrical should be de-energized at the breaker and ideally disconnected at the panel for the affected circuits. Gas lines must be shut off at the meter and capped by a licensed plumber — not just closed at the appliance shutoff. Water should be shut off at the main if plumbing is involved.
Personal protective equipment (PPE) is non-negotiable: safety glasses, dust respirator (N95 minimum — P100 recommended for older structures), hard hat, work gloves, and steel-toed boots. Drywall and plaster dust contains silica — a known carcinogen. Pre-1980 materials may contain asbestos, which is invisible and odorless but extremely dangerous. If you're hiring a contractor, verify they use proper respiratory protection and containment.
For any structural element — load-bearing walls, floor joists, roof framing — do not proceed without a structural assessment. In California, permits are required for load-bearing wall removal and structural demolition. DIY permits are available for homeowners in some cities, but the inspection process is the same. Consult a structural engineer if you're not certain what's load-bearing.
Understanding the Demolition Permit Process in California
California cities manage demolition permits through their local building departments. For residential demolition, the homeowner or a licensed contractor can pull the permit. Commercial demolition always requires a licensed contractor. The process typically involves submitting a permit application (online in most cities), paying permit fees, passing an asbestos/hazardous materials survey (required for pre-1980 structures), and scheduling a pre-demolition inspection.
Timelines vary significantly by city. Irvine and Aliso Viejo (Orange County) have online permit systems and typically issue residential demolition permits in 5–10 business days. Los Angeles City permits can take 3–6 weeks depending on the project scope. Cities in the Inland Empire (Riverside, San Bernardino County) often process faster — 3–7 business days for straightforward projects.
After demolition, a final inspection is required in most cities before the permit can be closed. Unpermitted demolition work is a serious liability — it can prevent property sale, invalidate homeowner's insurance, and result in fines. If you discover a prior owner did unpermitted demo work, a retroactive permit (and potentially a structural engineer letter) may be required before you can sell or refinance.
Choosing a Licensed Demolition Contractor in Southern California
California requires demolition contractors to hold an active CSLB license. The two most common license types for demolition are C-21 (Building Moving/Demolition) and B (General Building Contractor). Verify that the contractor holds an active license at cslb.ca.gov before signing any contract.
Beyond licensure, confirm the contractor carries general liability insurance (minimum $1M per occurrence) and workers' compensation insurance covering all employees. Ask for a certificate of insurance before work starts. If a worker is injured on your property and the contractor doesn't have workers' comp, you could be liable.
Get at least two on-site estimates before committing. Compare the scope of work in each estimate carefully — make sure they include the same items (permits, debris haul-away, site cleanup). The lowest bid isn't always the best deal. Check reviews on Google, Yelp, and the CSLB's own complaint history before hiring.
