Six places, and the first thing worth knowing is that they are two different propositions. Three of them sit on a barrier island you reach by bridge. Three sit on the mainland behind it. Access, insurance, what rebuilding would involve and which government writes the rules all follow from that before they follow from anything else.
The six areas
The island, and the mainland behind it
Topsail Island is a barrier island on the southeastern North Carolina coast, and it carries three incorporated towns. North Topsail Beach holds the northern end and lies in Onslow County. Surf City sits in the middle and is the unusual one: the town lies in both Pender and Onslow counties. Topsail Beach holds the southern end, in Pender County.
The three mainland communities behind it are not all the same kind of place either. Holly Ridge is an incorporated town in Onslow County. Hampstead is one of the seven unincorporated communities Pender County names, and Sneads Ferry sits outside Onslow County’s six municipal limits. Neither has a town hall of its own, so their planning, zoning and flood requirements are administered by the county.
What changes between them
- Who writes the rules. Inside a town, the zoning, building, beach access and parking rules are the town’s own. In Hampstead and Sneads Ferry there is no town, so Pender County and Onslow County administer land use, zoning, code enforcement and flood requirements directly.
- Which county you are in. Pender and Onslow keep separate tax offices, separate registers of deeds and separate planning departments. Surf City spans the line, so a Surf City tax bill is built from whichever county’s assessment file the parcel sits in.
- Coastal permitting. Oceanfront land on the island falls inside the state’s ocean hazard area, where a construction setback is measured landward from a vegetation, static vegetation or measurement line and scaled by a long-term shoreline change rate. Mainland waterfront can carry its own coastal permitting, but not that setback.
- Flood mapping. All six have mapped flood hazard areas — this is not an island-only question. The zone, the base flood elevation and the effective map date belong to the parcel rather than to the town, and they are what an insurer and a lender will ask you for.
- Federal eligibility. Part of North Topsail Beach lies inside a Coastal Barrier Resources System unit, where federal flood insurance is unavailable for buildings put up or substantially improved after the unit’s date. Nothing comparable applies to the other five.
- Getting there. The island has two crossings: the fixed high-rise bridge at Surf City carrying N.C. 50 and N.C. 210, and the high-rise bridge from Sneads Ferry that lands in North Topsail Beach.
Choosing an area
There is no ranking here and I am not going to tell you which of these is the good one. That depends entirely on what you want the property to do, and anyone who answers it before asking you is selling rather than advising. What I can do is tell you which questions actually separate these places.
- Start with the job the property has to do. Somewhere you will use yourself, somewhere that has to earn, or both at once. Those point at different parts of this map, and the third one is the hardest because the weeks you most want to be there are usually the weeks it would otherwise be earning.
- Judge the parcel, not the ZIP code. Flood zone, elevation, setback, insurance availability and federal eligibility are properties of a specific parcel and a specific structure. Two houses on one street can differ, and an answer about the town is not an answer about the lot.
- Establish which government you are dealing with. Town or county, and which county. That decides who issues your permits, whose ordinance governs the lot, and whose website is the one to check before you accept a rule someone has quoted at you.
- On the island, ask what has already been done to the shoreline. Nourishment, dune work and terminal structures are matters of public record. They tell you something about the past and something about what the town expects to keep doing.
- Drive it yourself, in season and out. I am not going to quote you a travel time — it depends on the month, the bridge and whatever NCDOT is building that year. The route is easy to test, and testing it is worth more than any figure I could give you.

Not sure which of these fits?
Tell me what you want the property to do and I will tell you honestly which of these areas is worth your time and which is not. That is a shorter conversation than most people expect.
