Council tightens accessory-structure rules, clarifies resin shed permit exemptions

The City Council voted to revise the municipal zoning language governing accessory structures, clarifying permit requirements for small resin sheds and aligning footing requirements for larger accessory buildings with the state building code.

City planning staff said the changes address ambiguities that had emerged in earlier language. Under the revised ordinance: prefabricated resin accessory structures up to 24 square feet remain exempt from a building permit; accessory structures larger than 600 square feet will require concrete footings consistent with building-code footing dimensions; and the ordinance adds an explicit list of acceptable exterior finish materials for accessory buildings (vinyl, painted wood, engineered wood, cement board, brick/stone excluding concrete block, painted or coated metal, and approved prefabricated kits).

Council members discussed whether small resin sheds could sit on patio blocks or pavers instead of a poured 4-inch slab; some members favored allowing pavers to reduce homeowner expense, while planning staff and others cautioned about rodent infiltration and inconsistent patio-block installation quality compared with a monolithic concrete slab. Councilmember Vitale recalled the earlier policy change was intended as a relaxation compared with previous, stricter footing standards, and the final ordinance preserved language requiring a weatherproof, monolithic-type floor for the permitted kit sizes.

Councilmember Roussy requested a narrow technical fix to ensure the clause allowing resin sheds without permits is explicitly exempted from the general permit paragraph; staff accepted that correction. After discussion, council voted to adopt the accessory-structure amendments.

Votes and action: Motion to approve the accessory structure ordinance amendments was adopted by the council.
