Asbestos Testing Before Demolition in Southern California
California law requires asbestos testing before demolition on structures built before 1980. Here's how the process works, what it costs, and how long it takes.
Why Asbestos Testing Is Required in California
Under California Health and Safety Code Section 25915, contractors must conduct a survey for asbestos-containing materials (ACMs) before any demolition or renovation that would disturb those materials. This applies to any building constructed before 1980 — the year asbestos use in construction materials was largely phased out.
Violating this requirement can result in fines of $25,000–$75,000 per day and criminal prosecution for contractors.
How Asbestos Testing Works
An asbestos survey is performed by a California-certified asbestos consultant (CAC). The process:
- Visual inspection of all suspected ACMs (textured ceilings, floor tiles, pipe insulation, roofing, drywall mud, etc.)
- Bulk sampling — small material samples collected and sent to an accredited laboratory
- Lab analysis via polarized light microscopy (PLM) or transmission electron microscopy (TEM)
- Written report identifying all confirmed and suspected ACMs with location and percentage of asbestos content

How Much Does Asbestos Testing Cost?
Asbestos survey costs in Southern California:
- Limited survey (1–3 suspect materials): $300–$600
- Comprehensive pre-demolition survey (full home): $600–$1,500
- Lab analysis per sample: $25–$50
- Air monitoring during abatement: $150–$300 per day
C&S Demolition coordinates certified asbestos consultants for pre-demolition surveys as part of our project management process.
How Long Does Testing Take?
The physical survey typically takes 2–4 hours for a standard home. Lab results take 3–7 business days for standard turnaround, or 24–48 hours for rush processing. If ACMs are found, abatement must be completed and air clearance testing passed before demolition begins.

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.
