Permit takeaway
Buffalo says a building permit is always required when working on a building unless the work fits one of the listed exceptions.
Zoning and placement
Even exempt work can still be affected by zoning, property-line, historic, pool enclosure, and site conditions.
Building and trade review
Buffalo lists exceptions for some one-story detached storage structures up to 144 square feet, certain playground equipment, shallow above-ground pools, fences not enclosing pools, and some retaining walls.
Call before applying when
Call before applying if the project affects a building, exceeds an exemption threshold, encloses a pool, supports soil or surcharge, or changes use or occupancy.
