Code: GC (Main construction professional)
Description: (General Contractor). This is an abbreviation for a person or company that manages and coordinates construction work for a building project. This person or company must register with the NYC Department of Buildings before getting permits and doing this work legally.
Practical Meaning: For you, this is the main construction professional with whom you work on your project, including hiring subcontractors and managing the job site. Just be sure that GC is properly registered with the NYC DOB before you rely on their competence,
Where You May See It: You may see this term on DOB permits, in BIS and DOB NOW when you look up your property, in contractor proposals and contracts, in emails from your architect or expeditor, and in DOB letters about your construction project.
Why It Matters: Choosing the wrong person in this role can lead to unsafe work, violations, fines, stop‑work orders, project delays, and higher costs for you as the owner. A qualified and registered General Contractor helps keep your project legal, safer, and easier to refinance or sell in the future.
