Key takeaways
- Only test what the project will actually disturb — that keeps the cost down.
- Demolition always needs a survey and SDAPCD notification in San Diego County.
- Testing before the crew arrives avoids expensive mid-job stop-work delays.
- An independent tester has no stake in whether abatement is needed.

San Diego demolition rules
Under SDAPCD Rule 1206, demolition of any structure requires an asbestos survey first and written notification to the District before work begins. Any asbestos found above the regulatory threshold has to be removed by a licensed contractor before demolition.
Renovation of commercial and multi-unit buildings has similar survey expectations when regulated amounts of material will be disturbed.

Avoiding mid-job delays
The most expensive asbestos test is the one done after a crew has already opened a wall. Testing a week ahead means the schedule, permit and budget are set before demo starts.
