10 Questions to Ask Your Demolition Contractor in Southern California
Before hiring a demolition contractor in Southern California, ask these 10 questions to verify licensing, insurance, permit experience, and scope clarity.
1–3: License, Insurance, and Experience
- What is your CSLB license number and what classification?
- Verify at cslb.ca.gov. Look for A (General Engineering) or B (General Building) with active status.
- Can you provide a certificate of insurance showing general liability and workers' compensation?
- Never hire an uninsured demolition contractor. Request a certificate naming you as additionally insured.
- How many demolition projects have you completed in this city in the past year?
- Local permit experience matters — each SoCal city has different requirements and processing times.
4–6: Scope and Permits
- Does your quote include permit filing, or is that extra?
- Permit fees and filing should be factored into any complete quote.
- Who is responsible for utility disconnects — me or your crew?
- Coordinating SCE, SoCal Gas, and water agencies takes weeks. Know who owns this step.
- Is hazmat testing included, or do I need to hire a separate consultant?
- For pre-1980 homes, asbestos survey must happen before demo begins. Clarify who coordinates this.

7–8: Debris and Timeline
- Is debris hauling and disposal included in your quote?
- Some contractors quote demo only and charge separately for hauling — get full scope in writing.
- What is the realistic timeline from permit application to completed demo?
- In SoCal, permits take 2–6 weeks. Factor this into your renovation schedule.
9–10: References and Warranty
- Can you provide 3 recent references in the same city?
- Call references and ask specifically about permit coordination, cleanup quality, and timeline accuracy.
- Do you provide a written scope of work with your contract?
- A vague verbal agreement is how disputes start. Any reputable contractor will provide a written contract with full scope, payment schedule, and completion timeline.

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.
