Utility marking, layout, access, post setting and why the crew may leave before the panels go up — the real sequence of a fence installation.

Privacy, slope, pool code, wind load and how each material fails — the site conditions that actually decide between aluminium and vinyl.

Posts before panels, whether the parts still exist, and the grandfathering trap that can make replacing an old fence more restrictive than repairing it.

The 48-inch height, 2-inch ground clearance, 4-inch sphere rule and self-closing gate requirements Pennsylvania adopts through the ISPSC — and why aluminium suits them.

Deeds, recorded plans, survey pins and when you genuinely need a surveyor — plus the decision most guides skip: building on the boundary or inside it.

Most residential fences in Pennsylvania are exempt from a building permit under the state UCC — but a separate municipal zoning permit is often still required.
