Typical project sizeNot enough valued permits to summarize.
Where they work
Primarily Commercial MEP — 94% of 424 segment-classified permits
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.
Direct contactNot in our data — we don’t fabricate firmographics.
What we won’t fabricate
S I Mechanical, LLC has 437 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
Aug ’240–17 permits/moAug ’26
permits per month
Monthly value isn’t shown: too few of S I Mechanical, LLC’s permits carry a reliable valuation, so we publish the count trend only rather than a value line built from gaps.
