[Phantom Lord]

This article does not provide anything approaching enough information to determine if the city is right that they owe property taxes of $300,000. Did this 'shelter' fail to apply for and receive proper permits and waivers? Are such things needed?

Wether or not it is "housing" is irrelevant. ALL property is subject to taxation without the proper 'waivers' for a lack of a better word.

[Psalm 73]

I believe that they had a long-standing agreement with the city, somehting to the effect that thier property taxes are waived because of the large amount of money that they save the city by performing these services.
That said,
The city moved against the mission right after thier (the cities) lawsuit against the gun manufacturers was thrown out.
They'll get thier money one way or another.
And a side note: the Mayor of B'port is in the midst of a HUGE Federal indictment regarding racketeering, etc.
(He's a Demoncrat, if you hadn't guessed already).

[DeaconBenjamin]

Nonprofits usually are not subject to property taxes. Presumably the city's argument is that the rescue mission is a for-profit masquerading as a nonprofit.
