Do I need a permit for pergola or trellis in Wethersfield?

Permit may be required

It depends. Whether pergola or trellis needs a permit in Wethersfield comes down to the details of your project.

Pergolas, trellises, and arbors are not named on the Connecticut list of work exempt from permit (CSBC R105.2), so a permit may be needed; ask the building official, especially for a structure attached to the house. A louvered or solid roof makes a pergola a roofed structure that is treated like a patio cover and generally needs a permit. No building permit may be issued until the zoning enforcement official certifies that the work conforms to zoning (CGS 8-3(f), repeated in CSBC R105.3.1.2).
