Do I need a permit for pavers, driveway, or hardscape in Lower Merion?
Most likely yes. Pavers, driveway, or hardscape usually requires a permit in Pennsylvania. Confirm the specifics with Lower Merion.
In Lower Merion the construction of driveways and patios typically requires a Minor Grading Permit with temporary stormwater controls such as silt fencing and tree protection. Patios, driveways, and walkways count as impervious surface. Adding over 1,500 square feet of impervious cover may trigger an engineered plan and a Runoff and Erosion Control Permit. Verify district impervious limits with Building & Planning at 610-645-6200. The Pennsylvania UCC lists what is exempt, at 34 Pa. Code Section 403.62(c), and it is narrower than most people expect. Sidewalks and driveways that are 30 inches or less above adjacent grade are exempt, and so is an uncovered deck whose floor is no more than 30 inches above grade. A patio is not on that list, so do not assume a paver patio is exempt until your municipality confirms it. A retaining wall is exempt only where it is not over 4 feet in height measured from the lowest level of grade to the top of the wall, and does not support a surcharge. Pennsylvania measures from grade, not from the bottom of the footing, so a wall that would pass the commonly quoted model-code test can still need a permit here. The UCC exemptions do not waive local zoning or stormwater rules, and a driveway apron in the public right-of-way may need a separate approval. Confirm with your municipality.
