not trying to be smart axx, but check your neighborhood and see what's out there as far as similar situations like yours. I have seen pictures of very tight installations with a 2-3 ft clearance from the condenser to a fence. codes can vary. I would keep calling Dept of Buildings in hope you can speak to someone.

you might consider calling an HVAC company who does work in your area. you will be relocating the new condenser to a different spot?

best of luck!

I have heard anything from 5-15' in different places. I'm sure it varies by jurisdiction. And also, the sometimes applies only to permanent structures or is governed also by height, so keep asking

the install instructions of the a/c unit will tell you minimum clearances. Building code is an entirely different animal. Unforunately, you have to follow building code first and manu specs second. However, if this guy is doing it on 'the side', he's probably not pulling a permit so code enforcement could be a moot point.

Thank you for your follow up emails, appreciate it.
Calling Buildings is useless but I had another idea that worked....called a local builder....was informed that it is 8 feet. thanks again.
