Primarily Commercial Alteration — 100% of 13 segment-classified permits
Blackstone Building Group has 23 permits, but too few carry a value we can stand behind — so we publish — for reliable value, never a guess. They still rank by volume; the dollar figure stays honest.
Monthly value isn’t shown: too few of Blackstone Building Group’s permits carry a reliable valuation, so we publish the count trend only rather than a value line built from gaps.
