Ahead of any building plan near Frankford, pull up the Millsboro zoning map early: the zoning district decides setbacks, lot size and uses. Covered here for Millsboro: who controls zoning for a given parcel, how to match a parcel to its district, and when a variance or rezoning comes up.
Getting started with the Millsboro zoning map
Within municipal limits, zoning usually comes from the municipality, so property inside this town answers to that map, especially near Milford. Outside those limits, near Ocean View or Frankford, county rules apply where they exist; confirm with the county office. The quickest way to tell which applies: ask whether the parcel near Georgetown is inside the boundary.
The free map to start with
The public parcel map for this area is the Delaware FirstMap State Parcels, and anyone can open it without signing up. If the land is near Millville, type a street address, an owner's name or a parcel number, and the matching parcel lights up. For land near Millville, the record panel typically gives the owner of record, assessed acreage, a parcel ID and often a sale date.
Calling planning staff
Have the parcel ID ready and describe the plan for the lot near Georgetown; staff can point to the right section of the ordinance. Also ask whether the lot near Georgetown is a legal lot of record, because nonconforming lots can carry limits.
Places you'll see on the map

Millsboro, DE: the basics
Millsboro sits in Sussex County, Delaware, which means parcel data comes from the county. In and around Selbyville, city or town hall handles matters such as zoning, permits and utilities inside its limits, and the county still keeps the parcel and deed records. Land beyond the town limits toward Frankford often follows county rules instead.
Legal descriptions in Delaware
Older tracts around Dagsboro are often described by metes and bounds, listing bearings, distances and landmarks. Town lots near Selbyville are typically described by lot and block, which is simpler to follow. Write down the legal description for the tract near Dagsboro before you request a deed or survey.
Backing up the map with records
For anything that matters, get the recorded deed through the county Recorder of Deeds; the parcel map near Frankford only summarizes it. If the land is near Dagsboro, have ready the book and page listed on the parcel record to skip a name search.
How to look up the district
Look up the lot on the Delaware FirstMap State Parcels first, copy its parcel ID, then compare it to the zoning map from the office covering Millsboro. On ground around Millville, district codes like R-1, C-2 or A-1 point to a table of rules in the ordinance; don't assume a code means the same thing everywhere.
Permits after zoning
Once zoning clears a project near Millville, a building permit is a separate step; health and road departments may weigh in on land near Ocean View.
What the district controls
If the land is near Georgetown, the ordinance spells out what's allowed outright and what needs approval. Near Selbyville, overlay districts, such as floodplain, historic or airport zones, can add rules on top of the base district.
Limits of the parcel data
Listed acreage is a tax-roll number; only a licensed surveyor establishes the real lines for a parcel near Ocean View. For acreage around Millville, records update in batches, so a deed recorded last month can take weeks to appear.
Asking for an exception
If the land is near Dagsboro, expect an application, a fee, notice to neighbors and a public hearing.
