PE Stamping & Sealing Services in District of Columbia

Professional engineers in the District of Columbia are licensed by the Board of Professional Engineering, under the Department of Licensing and Consumer Protection (DLCP). Firms practicing engineering must hold a Certificate of Authorization. A licensed professional engineer must be in responsible charge of engineering work performed in the District. A PE seal represents a responsible engineer's professional review and responsibility for eligible work — it is never sold as a standalone product. Where Apex Grid accepts a District of Columbia project, the licensed engineer of record defines the scope, reviews the design basis, performs or verifies the necessary engineering work, coordinates the eligible documents, and determines whether signing or sealing is appropriate. Apex Grid Engineering is a veteran-owned firm licensed in 49 states, with 10+ licensed professional engineers on the team.

Building permits in the District are issued by the Department of Buildings (DOB), created in 2022 from the former DCRA. DOB's permit center coordinates building, zoning, and trade permits, with the Historic Preservation Office reviewing work in historic districts and the Commission of Fine Arts weighing in on prominent sites. Third-party agency reviews (DDOT, DOEE, DC Water) overlay the building permit.

The District enforces the DC Energy Conservation Code and, for existing large buildings, the Building Energy Performance Standard (BEPS) — one of the most aggressive existing-building energy policies in the country. New construction targets net-zero energy under the District's CleanEnergy DC commitments, making envelope, lighting, and HVAC efficiency first-order design drivers.

Every District of Columbia submittal is engineered against the realities of the project location — these are the local conditions Apex Grid's engineers design around before anything is sealed:

• The District's Building Energy Performance Standard (BEPS) was among the first mandatory existing-building energy standards in the United States.
• DC's height limit — the Height of Buildings Act of 1910 — shapes structural and MEP design across the capital, capping most buildings well below high-rise thresholds.
• The Department of Buildings (DOB) was created in 2022 from the former Department of Consumer and Regulatory Affairs (DCRA), splitting permitting from licensing.
