A demolition permit is not the first form involved in tearing down an older Bay Area building. Before a crew can touch the structure, state and federal rules require someone to find out whether it contains asbestos — and to tell the air district, in writing, that the work is happening at all. This applies whether or not any asbestos turns up. Here is the order those steps actually happen in, who is qualified to do them, and the numbers that decide how much lead time a project needs.
Before demolition of most Bay Area buildings:
- 1A certified asbestos survey comes first. Cal/OSHA requires the building owner to determine the presence, location and quantity of asbestos-containing material (ACM) before work begins.
- 2Written notice to BAAQMD is required for every demolition, even when the survey finds no asbestos — generally at least 10 working days ahead, with a 72-hour paid option for residential buildings of four units or fewer.
- 3The federal EPA NESHAP rule runs in parallel with its own 10-working-day notice and its own, differently worded, threshold for how much material counts as regulated.
- 4If ACM is found, it has to be abated by a licensed abatement contractor before demolition starts — not during, and not by the demolition crew.
What the pre-demolition survey covers
Under California Code of Regulations, Title 8, Section 1529(k)(2)(A), “before work subject to this standard is begun, building and facility owners shall determine the presence, location, and quantity of ACM and/or PACM at the work site.” In plain terms: the owner, not the contractor, is responsible for finding out what is in the building before anyone starts tearing it apart.
That determination is a building survey performed by a person certified by California’s Division of Occupational Safety and Health (Cal/OSHA) — a Certified Asbestos Consultant, or a Certified Site Surveillance Technician working under one’s direct supervision — who has completed an EPA-approved building inspector course. The survey includes physically sampling suspect materials (flooring, roofing, insulation, stucco, drywall joint compound, and similar products common in older construction) and sending samples to a lab for analysis. A visual walkthrough alone does not satisfy this requirement.
Age is the rule-of-thumb trigger most people have heard: buildings built before 1980 are the ones most likely to contain asbestos-containing products, because many of those materials were phased out of use through the 1970s and 1980s. That is a reason to expect ACM, not a substitute for the survey — the regulation does not exempt newer buildings from the determination requirement, it simply describes where ACM is most often found.
Notifying BAAQMD: the J-number and the clock
Once the survey is done, the project has to be reported to the Bay Area Air Quality Management District under Regulation 11, Rule 2, regardless of what the survey found. BAAQMD assigns every notified demolition or renovation job a job number (J‑number), and that number is the district’s proof the notification requirement was met.
The standard notice window is at least 10 working days before demolition begins. BAAQMD also offers a 72-hour notice option, for an additional fee, specifically for demolition of residential buildings with four or fewer dwelling units — the category most home demolition projects fall into. Renovations that will disturb 100 square feet or linear feet or more of regulated asbestos-containing material (RACM) trigger the same notification duty as a demolition.
The requirement to notify “even if no asbestos is present” surprises a lot of homeowners. The logic is that the district needs advance notice of the activity itself — the demolition — not just advance notice of asbestos removal. Skipping notification because a homeowner assumes a newer structure has nothing to report is one of the more common compliance mistakes on small residential jobs.
Two rulebooks, two thresholds
Bay Area projects sit under two separate regulatory schemes that run at the same time: BAAQMD’s regional rule and the EPA’s national NESHAP asbestos standard (40 CFR Part 61, Subpart M, enforced locally by BAAQMD). They agree on the big picture — survey first, then notify, with roughly a 10-working-day runway — but they define “enough material to count” differently, which is worth knowing if a project is near the line.
| Rule | Regulated-material threshold | Standard notice window |
|---|---|---|
| BAAQMD Reg. 11-2 (regional) | 100 sq ft or 100 lin ft of RACM for a renovation; any demolition must be notified regardless of amount | 10 working days (72-hr paid option for 4-unit-or-fewer residential demolition) |
| EPA NESHAP (federal, 40 CFR 61.145) | 260 lin ft of pipe RACM, 160 sq ft of RACM on other components, or 35 cu ft where length/area cannot be measured | 10 working days before demolition or before stripping/removal work begins |
In practice, demolition and renovation projects in the Bay Area are filed once with BAAQMD, which administers both the regional rule and the delegated federal NESHAP program. The two threshold numbers above matter mainly for renovation-only projects deciding whether RACM removal crosses a reporting line; a full demolition gets notified either way.
If ACM is found
When the survey identifies asbestos-containing material, it has to come out before demolition — not alongside it. Abatement is its own licensed trade, separate from general demolition:
Handled by a licensed abatement contractor
- Containment and removal of identified ACM
- Air monitoring during removal, where required
- Packaging and labeling of asbestos waste
- Transport to an authorized disposal site with waste shipment records
Not part of general demolition scope
- A demolition contractor is not automatically licensed to remove ACM
- Breaking, grinding or disturbing suspect material before testing
- Disposing of ACM in a standard construction debris bin
- Starting structural demolition before abatement is verified complete
This sequencing is why the survey has to happen early in planning, not the week before a scheduled teardown: if ACM turns up, abatement has to be scheduled, completed and, on most projects, cleared before the demolition crew can mobilize.
Do not break, drill into, sand or remove suspect material yourself to “check.” Disturbing ACM is how fibers become airborne. If a material is suspected but unconfirmed, leave it alone and have it sampled by a certified consultant. This article explains the sequence of requirements; it is not instruction for handling asbestos.
What this means for a project timeline
For homeowners planning a demolition, the practical takeaway is to treat the survey and notification as the first scheduling item, not a formality squeezed in right before the crew shows up.
Before you set a demolition date
Tick each item as it is confirmed. This checklist works without JavaScript; with it on, ticks are saved in this browser only.
Because the standard BAAQMD and NESHAP notice windows both run at least 10 working days, and abatement (when needed) adds its own schedule on top, the realistic lead time between “survey ordered” and “demolition day” is almost always longer than homeowners expect on their first project. Building that lead time into a demolition bid is one of the things we check before quoting a teardown; see our guide to what a Bay Area demolition contractor handles for how this fits into the rest of the process.
Questions homeowners ask
Do I need an asbestos survey if my house was built after 1980?
The regulation does not set a hard age cutoff that exempts a building. Cal/OSHA Title 8 §1529(k) requires the owner to determine ACM presence before work begins regardless of construction date; pre-1980 buildings are simply where asbestos-containing products turn up most often. Confirm with your asbestos consultant or the district if you believe your building should be treated differently.
Do I still have to notify BAAQMD if the survey finds no asbestos?
Yes. Notification is required for demolitions regardless of whether asbestos-containing material is found. The J-number documents that the notification requirement itself was satisfied.
How long before demolition do I need to file the notice?
The standard window under both BAAQMD Regulation 11-2 and the federal NESHAP rule is at least 10 working days before demolition begins. BAAQMD offers a 72-hour paid option specifically for demolition of residential buildings with four or fewer dwelling units.
Can the demolition contractor remove asbestos themselves?
Asbestos abatement is a separate licensed scope from general demolition. If a survey identifies ACM, it needs to be removed by a licensed abatement contractor and verified before structural demolition proceeds, not performed by the demolition crew as part of teardown.
What is a J-number?
A J-number is the job number BAAQMD assigns to a demolition or renovation once it has been notified under Regulation 11, Rule 2. It is the district’s record that the notification requirement was met for that specific project.
Planning a demolition?
We walk through the survey, notification and permit sequence with you before a demolition date is set, so the schedule accounts for the district’s notice window from day one. Quartz Construction & Demolition holds California contractor license #1003436, which you can verify on the CSLB website.
