That is a choice the ham made by living in an HOA, and hence, not as much of a driver I would expect, as say a ham that does not live in an HOA.

We are in the process of looking for a new place, and there will be no HOA, or restrictive CC&Rs, period!

I will also run an RFI test overnight if possible, (https://www.nk7z.net/sdr-rfi-survey-p1/), or a full drive around if time is short...

One issue that pops up in terms of enforcement is the ability to even make a complaint - especially with respect to neighbors.  If you live in a HOA, your ability to demand changes to a neighbor's RF emitting devices gets kind of diminished given the fact that many amateurs aren't supposed to even have antennas with which they can hear the RFI in the first place.

    Part of the problem is that "enforcement" of harmful interference is
    handled by the Enforcement Bureau, which we have working somewhat
    well.  The emissions and marketing violations are enforced by the
    Office of Engineering and Technology, which knows of us, holds ARRL
    in high esteem, but we haven't worked out a process like we have
    with EB.  I think I can get that to change.

    How can I help set this up Ed?  I 100% agree...  You all handed the
    FCC an open and shut case with Home Depot, and as far as I know,
    nothing ever happened...  That does not bode well for enforcement...
