Firmographics
License & registration IDs on fileNot in our data — we don’t hold licensing-board registries, and this city’s permit records carry no licence number. This is a gap in our coverage, not a statement about this firm’s licensure.

What we won’t fabricate

Lorenzon Bros has 81 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.

Below our reliability threshold — too few filings carry a value we stand behind
Monthly activity
Sep ’240–2 permits/moJun ’26
permits per month

Monthly value isn’t shown: too few of Lorenzon Bros’s permits carry a reliable valuation, so we publish the count trend only rather than a value line built from gaps.
