The HOA is probably concerned about large antennas on the top of your house that you can easily see. You should be OK setting up a dipole or maybe vertical in your back yard. Make friends with your neighbors so they don't complain. I recommend a dipole for 15 m as your first antenna. Put it up in a tree or along your ridge peak with lightning protection. You will need to drive a ground rod for the lightening protection.

I am planning to make a folded balun for an EME antenna (https://ham.stackexchange.com/questions/3591/how-does-a-folded-balun-work). I have a NanoVNA. How do I connect the VNA to measure if the balun is tuned to the correct frequency?

Adding coils at the feed point will in effect increase the electrical length of the antenna which should bring down the swr. You will still need an antenna tuner with a very wide range to match it.
