San Mateo Received Decline in Value letter with BOE-441d. Do I need to do anything?

Two years ago I filed for decline in property and my property taxes got reduced.

Last year, I continued to receive a reduction.

Now I just received the letter below:

It includes Form BOE-441d (Request for Information) and some other form but this only requests "Income & Expenses" and details about rents. But for me this doesn't really apply because it's owner occupied.

Has someone else received a letter like this?

Do I need to respond or is this just "FYI"?

And most importantly, do I have a disadvantage receiving the reduction again this year when I do not react to this letter?
