Can I Get a PE Stamp for My Existing Home Plans in Maryland?

Maryland requires the sealing engineer to be in responsible charge of the engineering — the engineer must have exercised engineering judgment over the design. For existing plans, this means independent verification: the engineer recalculates structural elements, checks code compliance under the Maryland Building Performance Standards, and revises the drawings as needed before sealing. The seal must show the engineer's name, Maryland PE number, and date. Maryland engineers cannot seal work outside their area of competence. Montgomery, Prince George's, Baltimore County, Anne Arundel, and Howard review the sealed package with county amendments.

The review starts with the full drawing set: architectural, structural, foundation, and any prior calculations. The engineer checks the design against the design loads, verifies foundation design for Maryland's clay soils, and recalculates beams, columns, foundations, and the lateral system. Critical Area compliance is verified for Bay-adjacent sites. Deficiencies get redlined; the drawings are revised until the engineer can take professional responsibility. Bring the geotechnical report, the design criteria, and any prior plan-check comments. Incomplete documentation is the biggest delay.

Use this checklist before engaging an engineer for existing plans: • Engineer of record holds an active Maryland PE license, verifiable on the state roster • Plans are complete: architectural, structural, foundation, and prior calculations • Geotechnical report addresses clay soils for the specific site • Critical Area compliance verified where triggered • Prior plan-check comments included so corrections aren't repeated • Engineer confirms they'll respond to plan-check corrections on sealed sheets • Scope agreement covers review, revision, sealing, and corrections • Seal shows name, Maryland PE number, and date on every sealed sheet
