Hello good folks of BP,I need your suggestion on how to deal with Code Enforcement Inspector in San Jose, CA for unpermitted work.

if you are handy, the install should cost you about $200-300 in material, for a standard system, but for the next one i do im gona try Tjernlund RX2 system, they are $229 and install in a box sil, its not a "approved" system, however their is no "code" on radon in WI just guidelines by the EPA if it accomplishes the result, Im all for it instead of 3" PVC into the floor and out the roof. just my opinion. 

We bought a home in one of the nicer zip codes in our city, in the top school district at what we thought was a deal.

You can also make complaints about state employees who violate federal laws to federal officials, but you need to be specific as to what federal law or code is being violated. 

I assume the rental props must be in compliance with the city code, but what they are exactly?  

In addition do that during the renovation I am able to link a smart lock to the system to manage who is coming and going from the site by giving them a code to access the house and when they are done I can delete code and rearm the alarm, all from my office.  

It was then redone with PEX pipe because you can color code.

Are there certain zip codes I should stay away from?

It isn't that it's a legal non-conforming, but it is non-legal altogether, and he listed it as a multi-unit for sale.That's a violation of the RE code in every state. 

I give fedex, ups the code and they drop the packages in the hallway.
