I use a google voice phone number, I got it free and it's hard for the sign police to trace.

So far everyone from the county and police have been happy that I have purchased the property and want to turn it into a nice place again.

I had someone threaten to call the police once.

You will see that on your next C.E. course.If you are going to provide info via a web site make sure it is a factual site directly sourced from a reliable site i.e. the FBI, or local police department. 

If it's after hours, you can call the police and file a noise complaint.

Airbnb is a relatively new concept and cities are still adjusting their polices on the legality of renting out a place for less than 30 days which would normally require a hotel permit and the owner or traveler to pay occupancy taxes.

Homes are in a C+ neighborhood right next door to a large church and police department.

I plan on utilizing Bandit signs in the unincorporated areas of San Diego so I shouldn't run into too many issues with the sign police (maybe some PO'd homeowners in the area with shotguns--->I'll take my chances).

I think you'll have more issues making sure the home is lead paint free so you can get your certificate to rent than the mold (don't think that is as aggressively policed yet).
