Do I need a permit for shed or accessory structure in Lower Merion?

Permit required

Yes. In Pennsylvania, shed or accessory structure generally requires a permit, and Lower Merion is no exception.

Pennsylvania's threshold is far higher than most states, so do not apply a number you read nationally. Under 34 Pa. Code 403.1(b)(3) the Uniform Construction Code excludes a structure with a building area of less than 1,000 square feet that is accessory to a detached one-family dwelling, and the listed structures are carports, detached private garages, greenhouses and sheds. That exclusion is from the UCC, not from your municipality. Most Pennsylvania municipalities still enforce setbacks, easements and size or placement limits under a local ordinance, and Pennsylvania has no unincorporated land, so a municipality always covers your address. Larger accessory buildings, or any that get electrical, plumbing or heating, fall outside the exclusion and are back under the UCC. Where a municipality has opted out of enforcing the UCC, residential permits and inspections are handled by a state-certified third-party agency the owner or contractor contracts directly. In Lower Merion an accessory structure such as a shed under 200 square feet requires a zoning permit, and one over 200 square feet requires a building permit. Both require review against district setbacks and impervious coverage limits. Review setbacks, impervious surface limits, and floodplain restrictions for your zoning district before applying. Lower Merion has many zoning districts; confirm yours with Building & Planning at 610-645-6200.
