Who files the most construction permits as architect or engineer of record in NYC?

Ashraf Corp, with 13,587 DOB NOW: Build filings on record — ranked by filing volume, the only firm-level activity signal NYC's public data supports (not revenue, headcount, or a design-quality ranking).

How are architecture and engineering firms ranked on this page?

By the number of DOB NOW: Build job filings naming that firm as applicant of record — live from NYC Department of Buildings, not a self-reported or paid ranking. RA (Registered Architect) and PE (Professional Engineer) are DOB's own two dominant applicant disciplines.

Is the architect shown on a Development page the same as the firms ranked here?

No. A Development page's "Architect / Engineer of Record" is the individual who signed that one filing, from the legacy Job Application Filings dataset (no firm name recorded). This page uses a separate, newer DOB NOW dataset that does record a real firm name.

All Firms & Practitioners

Ranked by DOB NOW: Build filing volume — the clearest firm-level activity signal in public DOB records.

Methodology

This ranks the businesses (including sole-practitioner architects and engineers registered under their own name) listed as applicant on DOB NOW: Build job filings, by filing count. It is not a revenue, headcount, or design-quality ranking, and "applicant of record" means the professional who signed and submitted the filing — not necessarily the credited design architect on every drawing set for a large project. Only the two dominant DOB applicant disciplines (Registered Architect, Professional Engineer) are included; a handful of rarer codes (e.g. landscape architect) are excluded as too sparse for a meaningful ranking. Refreshed nightly rather than re-scanned on every visit, since building it means scanning hundreds of thousands of DOB NOW filings.

How are architecture and engineering firms ranked on this page?: By the number of DOB NOW: Build job filings naming that firm as applicant of record — live from NYC Department of Buildings, not a self-reported or paid ranking. RA (Registered Architect) and PE (Professional Engineer) are DOB's own two dominant applicant disciplines.
Is the architect shown on a Development page the same as the firms ranked here?: No. A Development page's "Architect / Engineer of Record" is the individual who signed that one filing, from the legacy Job Application Filings dataset (no firm name recorded). This page uses a separate, newer DOB NOW dataset that does record a real firm name.
