What it takes to build here — permits, zoning, and septic — scouted from Lehigh County’s own official sources.
A building permit is required under Pennsylvania's statewide Uniform Construction Code (UCC), administered and issued by the municipality (or its third-party agency), not by Lehigh County.
PA Department of Labor & Industry - Uniform Construction Code ↗Zoning in Lehigh County is administered by individual municipalities under the PA Municipalities Planning Code; the county administers subdivision/land development (SALDO), not county-wide zoning.
Lehigh County Ordinances (Subdivision and Land Development) ↗On-lot septic permits are issued by the municipality's Sewage Enforcement Officer under the PA Sewage Facilities Act (Act 537), overseen by PA DEP.

Whether a new home can legally get its own water here — the sub-state groundwater regime, from Pennsylvania’s water agency.
This basin is under active state management — new water use is scrutinized, though a domestic well is usually still allowed.
Pennsylvania does not permit private water wells (reasonable-use doctrine). Large withdrawals may need DRBC approval (>10,000 gpd inside the SE PA Ground Water Protected Area) or SRBC approval (>=100,000 gpd), but a household well is far below every threshold.
Limit: no state permit (unregulated private wells)
PA DEP — Private Wells ↗DRBC protected area where new/expanded withdrawals averaging >10,000 gpd need a DRBC Protected Area Permit (vs 100,000 gpd elsewhere) because development lowered water tables and depleted streams. Household wells (~200-400 gpd) are below the threshold and unaffected; only Montgomery is wholly included.
Delaware River Basin Commission — SEPA GWPA ↗Riparian state (water rights tied to land). Groundwater rules change and basin boundaries follow the aquifer, not the county line — confirm current well and appropriation rules with the Pennsylvania state water agency before you buy or drill.Groundwater governance as of Jul 2026, cited to each administering agency.
