Building age doesn't matter: South Coast AQMD requires an asbestos survey before any renovation or demolition

One of the most persistent misconceptions in Southern California remodeling is that buildings past a certain construction date are automatically exempt from asbestos requirements. They aren't. In its Rule 1403 Frequently Asked Questions, South Coast AQMD states plainly that "a survey is required regardless of the age of the building" and that "there is no date when asbestos in building materials was banned."

There's a reason no cutoff date exists. Asbestos has never been fully banned in every U.S. building product, and imported materials can still contain it. Building age is simply not a reliable indicator of what's in your walls, ceilings, or flooring.

South Coast AQMD Rule 1403 — Asbestos Emissions from Demolition/Renovation Activities — sets the work practices for asbestos on renovation and demolition projects across Los Angeles, Orange, Riverside, and San Bernardino counties.

Under the rule's current requirements, a survey for asbestos-containing materials (ACM) must be conducted and documented before any renovation or demolition begins. The survey must be performed by a Cal/OSHA-certified asbestos consultant or inspector, documented in writing, and it must identify every ACM that will be disturbed, its condition (damaged or intact), and its friability.

For demolitions, the survey requirement applies without exception. For renovations, the only limited carve-out in the rule relates to notification thresholds — single-unit residential projects removing less than 100 square feet of ACM surface area — and even in those cases, AQMD's advisory notes that a survey must still be conducted and documented.

When the survey identifies ACM that will be disturbed, notification must be filed with South Coast AQMD online before work begins, and removal must be performed by an abatement contractor registered with Cal/OSHA.

If the asbestos is damaged or disturbed, a Procedure 5 cleanup plan must be prepared by a certified asbestos consultant and approved in writing by AQMD staff before abatement can start. This applies regardless of the size of the project.

Don't use the age of the property to decide whether testing is needed — the rule already answers that question. Before you renovate or demolish, have a Cal/OSHA-certified inspector survey the materials you plan to disturb.
