RE: Whether the Demolition standard applies to moving a residential structure. 29 CFR 1926 Subpart T – Demolition.

Question: When moving an entire residential structure, does 29 CFR 1926 Subpart T, the Demolition standard, apply?

Answer: It is our understanding that moving a residential structure typically involves the following process: First, employees complete pre-move tasks such as disconnecting utilities. Then, holes are made in the foundation, and steel I-beams are run through the holes and under the structure. Dunnage piers are built up to support hydraulic jacks. The jacks then lift the entire structure from its foundation. After placement of the beams on dollies, the structure is moved to its new location and laid on the new foundation. Finally, post-move tasks such as connecting to utilities lines are commenced.

The provisions of the demolition standard, 1926 Subpart T (1926.850-1926.860), address hazards associated with demolition. The procedure described above is not a demolition process; in fact, it is in a sense the opposite – a procedure designed to keep the structure intact. Therefore, the demolition standard would not typically apply to such a procedure.
