Exterior Painting (brick) - permitting process?

[Rishi B.]

Hi all - thanks in advance for your help! I'm looking to update the brick exterior on a 6-flat. I've been trying to research whether any type of permit is required. 

I do see that masonry cleaning/chemical wash (the prep work) -
"may require an air pollution control permit from the Environmental Permitting and Inspections Section of the CDPH"

And then digging further I see there's also a separate Architectural Surface Cleaning Permit could be required.

Anyone have experience with this? Thanks!

depends partially if you're going to remove the existing paint. if so, it might contain lead depending on age and would require special handling...
