For a structural inspection or on-site walk-through, Lebra Engineering & Design charges a flat $800 for the on-site walk-through and $1,500 for a written, stamped report — a signed report you can hand to a building department, buyer, insurer, or attorney.
For structural design — a new beam to remove a wall or build an addition, an ADU, deck framing, or a foundation repair — the fee depends on scope, so we quote each project individually and return the quote within one business day.
Size and complexity, whether drawings already exist, the number of site visits, the building department’s requirements, and your turnaround all move the number. A single beam is a modest, well-defined job; a full addition with new foundations is larger.
A stamped design gets your permit approved the first time, keeps the work safe and compliant under the Massachusetts State Building Code (780 CMR), and puts a licensed professional behind the numbers. A rejected design — or a wall that sags later — costs far more than the engineering.
