HOA rules regarding outdoor mounting of antennas were largely preempted by federal law almost 20 years ago. See

San Diego area antenna users have a complicated setup due to the three primary transmitters sites: Mt San Miguel, La Jolla, and Tijuana.
There's no need for either the DB8 or the DB8e. The ClearStream 2V is the ideal option for much of San Diego but you will need to make an adaptation as follows:
You will probably need a longer mast. If you're in an attic, then almost anything from an old broom handle, a piece of plastic pipe, or anything similar may be used.
Assemble the basic antenna WITHOUT the reflector screen. Mount it to the pole and situate is so that it's oriented with the loop openings facing generally north/south and adjust for best reception of your UHF stations.
Add the VHF module to the system attached separately to the mast but rotated so it is perpendicular to the direction of La Jolla. Adjust as needed. See below.
What this does is create a UHF antenna that is bi-directional north/south and a bidirectional VHF antenna that is NW/SE, both with an effective beamwidth of 65-70°.
You do not need nor should you use any amplifiers, they are unlikely to help and are far more likely to cause new problems.
One complication that I do see is related to your desire to provide Mexican programming for your wife's viewing. Estrella TV is carried in the SD area on KSDX-LD, a low power channel 9 signal from Mt San Miguel. Because of this, you'll probably need to see if you can readjust the VHF dipole so it's facing more towards the north or even more easterly to see if you can cover both VHF transmitter sites.
If you have problems with reception of VHF channels, the first thing to do would be to install an FM filter.
