Do I need a permit for pergola or trellis in Boston?
Most likely yes. Pergola or trellis usually requires a permit in Massachusetts. Confirm the specifics with Boston.
The statewide list of work exempt from permit (780 CMR 51.00 R105.2) does not include pergolas, arbors, or trellises, so check with the building official before building one. A pergola with a solid or louvered roof is treated like a patio cover under Appendix AH, which Massachusetts adopts in full. Local zoning setbacks and historic district rules may apply even where no building permit is required.
