If you are tearing down a house anywhere in Orange County, your schedule does not start with the excavator. It starts with an asbestos survey and a notification to South Coast AQMD. Rule 1403 sets both, and most owners find out about it about a week after they wanted to start.
Every demolition needs an asbestos survey first
Before any demolition or renovation, the building has to be surveyed for asbestos-containing material, and the survey has to be done by a Certified Asbestos Consultant (CAC) or a Certified Site Surveillance Technician (CSST). Not a contractor's judgement call, not a visual walkthrough: a signed survey report from a certified consultant.
In Orange County that usually means checking the places asbestos actually hides in housing built between the 1950s and the 1970s: mortar-bed tile and mastic, sheet vinyl and its backing, acoustic ceiling texture, drywall joint compound, roofing felts, duct wrap, and the paper facing on old insulation.
The 10 working day notice is what moves your start date
Once the survey is done, a notification goes to South Coast AQMD with the fee, and it is due 10 working days, or 14 calendar days, before work starts. Holidays push that out further. This is the single most common reason a tear-down slips: the crew is booked for next week and the notice has not been filed.
Plan it the other way around. Survey first, notification filed, then pick the start date.
Yes, even if the survey comes back clean
A clean survey does not remove the notification requirement. All demolitions require notification so that AQMD can inspect and confirm there is no asbestos in the building before it comes down. Testing clean is not a reason to skip the filing.
Asbestos comes out before the structure does
Where the survey does find asbestos, it is removed before demolition by a licensed abatement contractor, as its own phase with its own schedule. That is separate scope from the demolition, and you should see it as a separate line in your pricing rather than buried in a lump sum.
For renovations rather than tear-downs, the trigger is disturbing more than 100 square feet of intact asbestos-containing material. Below that, some removals are exempt, but the obligation to survey before the work does not go away.
Fees, revisions and cancellations
The fee goes with the notification, is based on the size of the project, and is not refundable. If your dates move, you file a revision, and if the revision puts the job in a higher fee category you pay the difference. Cancelling a notification is fee-exempt.
Move your dates twice and you have paid twice for the same job. It is another argument for locking the schedule down before filing.
The exceptions, and what they are not
Owner-occupants of a single-family home have limited exemptions and may do some of their own work, though other Rule 1403 requirements still apply. Those exemptions do not extend to condominiums, townhouses, or apartments.
Government-ordered demolitions can skip the 10-day wait with a written order, the survey report, and confirmation that the asbestos was removed. A tight construction schedule is not an emergency.
What this means for your timeline
For a standard Orange County tear-down, budget roughly three weeks from go-ahead to the first day of demolition: a few days to get a consultant out and get the report back, then the 14 calendar days of notice. Abatement, where it is needed, sits on top of that.
None of this is a reason to panic. It is a reason to call early. When we walk a property, two of the first questions we ask are who is doing your survey and whether the notice has been filed, because those decide when the house comes down, not the machine.
