Counted from DOB NOW: Build – Approved Permits, grouped by the City's own servers, so these are totals rather than a sample. Rows are matched to Structure Tone Inc by business name after normalizing punctuation, legal suffixes, abbreviations and DOB's fixed-width truncation — never by a looser prefix, which would pull in different firms with similar names. Job costs are the applicant's filed estimate, not a contract value, and some permits carry none. A permit is one approval, not one project: a single building can need dozens. Owners are the owner of record on the permit, often a single-purpose entity rather than the developer brand.

NYC Contract Awards Won
Cross-referenced against the city's own "Recent Contract Awards" dataset by vendor name — a DOB permit-pulling contractor and a procurement-awarded vendor are two different city record systems, joined here by an exact match after normalizing punctuation, legal suffixes, and common abbreviations. A real business can legitimately win contracts under a slightly different legal name than the one on its DOB permits, so an empty result here doesn't mean Structure Tone Inc has never won a city contract — only that no exact name match was found.

Public Safety & Compliance Records(76)
These are citywide building-equipment compliance filings (including elevator and boiler safety compliance), ECB violations, and DOB complaints recorded at the same addresses as this company's projects above — not violations or complaints attributed to or caused by Structure Tone Inc. NYC's public data does not link any of these records to specific contractors (ECB violations in particular are almost always filed against the property owner), so no company safety score is shown or implied.

Stop Work Orders(0)
DOB Stop Work Orders issued at this company's project addresses. A minority reference a job number in their text — when that job number matches one of Structure Tone Inc's own permits, it's marked directly linked below. The rest are address-level only (same building, different or unspecified job) and are shown as context, not attributed to this company.
No Stop Work Orders on record at these addresses.
Layoff & Closure Notices (WARN)(0)
Matched by business name against NYS DOL's official WARN Dashboard (layoffs/closures affecting 50+ employees). This is an approximate name match, not verified — WARN notices are filed under whatever legal entity operated the site, which can be a parent company, subsidiary, or DBA different from the name on a DOB permit. Confirm at the source link below before treating a match as confirmed. As of 2026-08-04, no NYC-area construction company appeared on the current WARN list — an empty result here is the norm, not a bug.
