South Portland Maine Fence, ADU, Driveway, and Excavation Permit Guide

South Portland residential projects can involve fence height thresholds, ADU zoning permit review, driveway curb-cut review, excavation permits, and code-enforcement inspection scheduling.

Permit takeaway

South Portland says residential fences under six feet high do not need a permit, while fences higher than six feet need permitting and are subject to setback requirements for the parcel.

Zoning and placement

ADUs require a zoning permit application process in addition to the building permit application, while parcel-specific zoning questions should be reviewed with Code Enforcement.

Building and trade review

Driveway excavation or curb-cut work can require driveway excavation, curb-cut, and excavation permits depending on whether public right-of-way digging is involved.

Call before applying when

Call before applying if the fence exceeds six feet, the parcel has unusual setbacks, an ADU is planned, a driveway entrance is new or widened, or any digging touches the city right-of-way.
