Out here in this city suburbia.
An empty block incurs, land tax, unimproved valuation rates, water charges , sewerage charges.
And if have the adjacent block with house & pool, you have to pay penalty water rates , for excessive water use. I told one owner to have the water put on the spare block, just for the pool filling & car washing . Saved lots of money & arguments over those pool parties , as well as washing friends cars .
