Ahead of any building plan near Delaware City, check the Newark zoning map first: the zoning district can make or break the plan. In this Newark guide: who controls zoning for a given parcel, matching a lot to its zoning district, and what to ask the planning staff.
Reading the Newark zoning map for one lot

Outside those limits, near Delaware City or Newport, county rules apply where they exist; ask the county planning office to be sure. To find out which side of the line a parcel is on: ask whether the parcel near Elsmere is inside the boundary.
