Or it means I'm not planning to sell for a very very long time and thus appreciate the tax break a lower appraisal gives me. The same logic applies if I am a landlord--as long as the rent and thus cash flow stays the same, I don't particularly care about what some appraiser says the property is worth.

Anyways, it seems to me that restrictions on construction are a lazy owner's way to maintain property values. After all, there is no better way to add value to and capture the revenue from my house than to add another 2 stories to it and rent it out. I do own the land underneath it, after all.
