Carolina Beach zones its own ground under its own Unified Development Ordinance, inside New Hanover County. The county's Building Safety department issues the building permit for every house built here.

The town adopted its Unified Development Ordinance in July 2024. It has amended the UDO since, most recently in August 2025. The version in force on the day an application goes in is the one that governs. Building Safety is the same county department that issues building and trade permits for the unincorporated county.

Several offices carry a residential project through the process. The UDO Administrator, designated by the town manager, interprets and enforces the ordinance. A question of interpretation goes to the Administrator first. An appeal goes to the town's Board of Adjustment. A separately designated Floodplain Administrator runs Article 5, Flood Damage Prevention, and is the official answerable for the town's standing in the National Flood Insurance Program. CAMA is the state's Coastal Area Management Act. The UDO names the town Building Inspector as the designated official for CAMA minor development permits. Before any building permit issues, the inspector must decide whether the parcel lies inside a CAMA Area of Environmental Concern (AEC). A parcel inside one gets that finding in writing. Once that determination clears, New Hanover County Building Safety issues the building permit itself, plus every trade inspection behind it, through its COAST portal.

A single-family house that needs a CAMA permit usually needs a minor permit. Local governments review, issue and administer these permits under contract with the state's Division of Coastal Management, to the Coastal Resources Commission's standards. The Division's own guidance calls for a decision within twenty-five days of a complete application. On this island, the ocean hazard and estuarine shoreline AECs between them touch much of the town's shoreline. That CAMA review runs alongside the zoning review. Our six-phase process builds it into the permit path from the start.

Article 3 describes four residential districts that carry single-family houses. R-1 allows both single- and two-family houses. R-1B, R-2 and R-3 are single-family only, stepping down in density. Table 3.3 gives R-1 and R-1B the same footprint rules. The minimum lot is 5,000 square feet, with fifty feet of width. The front setback is twenty feet, the rear ten feet, and each side seven and a half feet. Those dimensions fit the fifty-by-one-hundred lots much of the older grid was platted in. R-2 asks for 7,000 square feet and seventy feet of width, with a twenty-five-foot front setback. R-3 asks for 12,000 square feet and eighty feet of width. All four districts cap lot coverage at forty percent and impervious surface at sixty-five percent.

Height is where the numbers diverge. Section 3.13 sets fifty feet as the townwide ceiling on structure height. The one exception is a conditional-zoning proposal in the central business district. Below that ceiling, lower caps apply: the table holds R-2 to forty-five feet and R-3 to forty. A Height Overlay District adds one more cap. It is drawn on the official zoning map to protect the town's traditional, mostly year-round neighborhoods. Inside it, height is capped at forty-five feet, regardless of base district. The town measures building height from the average front street line up to the highest appurtenance on the structure (section 7.3). Which district a lot sits in, and whether the overlay reaches it, is read from the zoning map with the UDO Administrator.

A Carolina Beach lot rarely starts empty.

New construction in Carolina Beach can begin with a demolition permit. The lot is already a lot, with a cottage on it and a district around it. The new home we design for it has to fit several rules at once. It has to fit a 5,000-square-foot parcel, under a forty-percent lot-coverage cap and a sixty-five-percent impervious cap. The house has to sit inside the setbacks, under the height its district and any overlay allow. It has to sit at or above the regulatory flood protection elevation, and behind whichever CAMA line applies. Each rule is common on its own. Together, on fifty feet of width, they are the design problem. A good plan for a Carolina Beach lot treats them as its shape.

Renovating an existing raised cottage in Carolina Beach runs into the substantial-improvement rule first. The town sets that threshold at forty-nine percent. The rule counts the cost of repair, reconstruction, addition or other improvement over any one-year period. When that cost reaches forty-nine percent or more of the structure's pre-improvement market value, the work is a substantial improvement. The whole structure then has to be brought up to the current regulatory flood protection elevation, from top to bottom. That holds whatever portion the renovation actually touched. The town's threshold sits one point below the fifty percent the federal flood insurance rules set as the minimum. A pre-FIRM cottage is one built before the town's first federal flood map took effect. For one of those, the line often turns a renovation into a choice. One path keeps the scope deliberately under the line. The other lifts the house and designs the elevation, the new foundation and the load path together.

Whether an ADU is feasible in Carolina Beach depends on the UDO as published. The definitions, amended in August 2025, recognize an accessory apartment as a self-contained dwelling unit inside an existing structure, for a single family. The published ordinance sets no separate definition for a detached accessory dwelling, and gives it no separate authority either. Section 3.6 then limits a residential lot to one customary accessory building, beyond a short list of exemptions. That building is capped at a quarter of the principal building's lot coverage, and at fifteen feet in height. It stays out of the front and side yards, and at least five feet off the rear line. The ordinance says plainly that it may not be used as a dwelling, or rented for income. Anyone weighing a backyard unit on a Carolina Beach lot should ask the UDO Administrator, who confirms what a specific parcel may build. Sometimes an accessory apartment inside the existing structure is what fits the lot. Then it is held to the same envelope and moisture standard as the house around it.

Two more ordinances catch teardowns on narrow lots. The first is the town's landscape ordinance. It applies to regulated vegetation across the whole municipal limits, dune lots and inland lots alike. It requires a tree or landscape plan for clearing, grading or any other earth-disturbing work. A single-family lot must then carry at least one tree per twenty-five linear feet of street frontage. Each tree has to be six feet tall and two inches in caliper when planted. Trees on public rights-of-way fall under a separate section of the Code of Ordinances, administered through the town manager's office.

The second ordinance is stormwater. A town stormwater drainage permit comes in two tiers. The first tier needs no engineered plan; it covers clearing to bare soil or adding impervious surface. The second tier needs an engineered drainage plan. That tier covers grading, filling, any building permit that increases impervious surface, or a site with a history of flooding or erosion. No building permit issues until the town manager or designee certifies the approach. Alongside it sits the impervious-coverage plan. It is required once a project adds more than 325 square feet of impervious area. A licensed surveyor, architect, landscape architect or engineer has to prepare it once the addition reaches 500 square feet. On a lot already near the sixty-five-percent cap, the plan counts the driveway, walks and equipment pad before anyone grows attached to them.

Snow's Cut turned this stretch of sand into an island.

Carolina Beach holds the north end of Pleasure Island, with the Atlantic on one side and Myrtle Grove Sound on the other.

The ground here was a peninsula until Snow's Cut was dredged in 1929 and 1930, which made it an island. The cut is the Intracoastal Waterway channel between the Cape Fear River and Myrtle Grove Sound. One road bridge crosses it, carrying US 421. Apart from the ferry landing at Fort Fisher, on the island's far end, that bridge is how every person, every truck and every inspector arrives. South of the town line, the same strip of sand continues as Kure Beach, then Fort Fisher, then the mouth of the river.

The middle of town is the Boardwalk and the older commercial grid around it. Carolina Beach Lake sits a couple of blocks off the ocean. The north tip is Freeman Park, the drive-on beach that runs toward Carolina Beach Inlet. That inlet is man-made. The Army Corps of Engineers opened it in 1952, and dredges it regularly. NC Sea Grant's researchers connect that maintenance to erosion on the southern end of Masonboro Island, across the channel. Much of the island's river side is Carolina Beach State Park, 761 acres holding Sugarloaf Dune. That fifty-foot rise is a landmark river pilots have steered by since 1663.

Between those edges, most lots fit one of five situations:

• Strand lots facing the Atlantic, much of that frontage in CAMA's ocean hazard area and in Zone VE or the Coastal A Zone behind it
• Canal lots off Myrtle Grove Sound, usually with a bulkhead and often a dock, where the condition of both is the first thing to read
• Open sound-front lots looking west across the water toward the mainland, with no canal between the house and the sound
• Parcels near the bridge that front Snow's Cut and the Intracoastal Waterway traffic that uses it
• Interior grid lots a block or more from either shore, the most conventional ground in town and still a short walk from salt water

That last point is the one the whole island shares. Pleasure Island is narrow enough that no lot on it is inland in any sense that matters to a fastener or a piece of mechanical equipment. Salt air reaches the sound side as surely as the strand, and the design has to assume it will. The island does have municipal service: the town supplies water and sewer inside its limits, so there are no well and septic questions here.

Much of the residential grid went up before the current flood maps and wind tables existed. So much of the new construction here replaces an older raised cottage on a fifty-by-one-hundred lot. What goes up has to satisfy a zoning district, a flood elevation and a wind standard the original house never knew. New homes here are custom homes, shaped by a lot that already has a history.

The ocean, the sound and Snow's Cut each flood their own way.

Zone VE (ocean strand)

bottom of the lowest horizontal structural member at or above the regulatory flood protection elevation; no floodproofing; open or breakaway space beneath; engineer- or architect-certified foundation

Coastal A Zone (landward of VE, seaward of the LiMWA)

the same elevation and breakaway standard as VE, plus engineered flood openings in any enclosure below the flood elevation

Zone AE (many canal and sound lots)

top of the lowest floor at or above the regulatory flood protection elevation

Regulatory flood protection elevation, townwide

base flood elevation plus two feet of freeboard; at least two feet above highest adjacent grade where no BFE has been established

Service equipment, every flood hazard area

electrical, heating, ventilation, plumbing and air-conditioning equipment at or above the regulatory flood protection elevation, or designed and installed so water cannot enter it during the base flood (section 5.124)

Dredging Snow's Cut in 1929 and 1930 put the Atlantic on one edge of Pleasure Island. It put Myrtle Grove Sound, or the cut itself, on the other edge. So two lots a few streets apart can draw different flood answers, while sharing one wind figure. The 2018 NC Residential Code's Table R301.2(4) sets the county's wind line at US 17, under footnote h. New Hanover County is 140 mph to the west and 150 mph to the east. Pleasure Island sits entirely on the 150 mph side. Exposure category is left to the design professional. It turns on what stands between a given lot and open water. The flood zone, though, changes from block to block, with the shoreline a lot faces.

Along the strand, many ocean-facing lots sit in Zone VE, the coastal high hazard area. Article 5 of the UDO treats VE strictly. The bottom of the lowest horizontal structural member has to sit no lower than the regulatory flood protection elevation. Floodproofing may not substitute for elevation. The house must sit landward of the reach of mean high tide, and inside every applicable CAMA setback. The space beneath it stays free of obstruction, apart from breakaway walls, open lattice or insect screening. A registered engineer or architect must certify the foundation design, on the state's V-Zone certification form.

Landward of Zone VE, the flood map shows the Limit of Moderate Wave Action, or LiMWA, line. The Coastal A Zone is the band between that line and the VE zone. It is usually not labeled as a zone on the map at all. The UDO holds that ground to the same elevation and breakaway-wall standard as VE itself. It adds one requirement VE does not spell out: any enclosure below the flood elevation needs engineered flood openings, as well as breakaway construction. In practice, a lot one street back from the ocean may be designing to V-zone rules without being in Zone VE. Catching that distinction is the site analysis's job.

Canal and sound lots along Myrtle Grove Sound often carry an AE designation instead. The measurement changes with that zone. In an AE zone, the reference level is the top of the lowest floor. In a VE zone, it is measured to the bottom of the lowest beam. The regulatory flood protection elevation itself is set the same way everywhere in town. Where a base flood elevation has been established, it is that elevation plus two feet of freeboard. The base flood elevation is the height water is expected to reach in a flood with a one-percent chance in any year. Freeboard is the extra height the town adds above it. Where no base flood elevation has been established, the protection elevation is at least two feet above the highest adjacent grade. The numbers come from the parcel. A current FEMA panel from the Map Service Center, or the NC Flood Risk Information System, gives the reading, checked against the lot.

On this island the flood zone picks the foundation, and three different shorelines sit a few blocks apart.

CAMA adds its own line on the ocean side. The state's oceanfront construction setback is measured landward from the first line of stable natural vegetation. It is scaled to the size of the structure. At the default setback factor, it starts at sixty feet for a house under 5,000 square feet. It rises through the size bands to 180 feet for the very largest structures. Where the Division of Coastal Management's long-term erosion rate for a stretch of shoreline is higher, the factor, and the setback, rise with it. Carolina Beach then adds a line of its own. No privately owned structure may cross the Carolina Beach Development Line, recorded in the New Hanover County Register of Deeds. That holds whatever the state setback works out to. Beach crossovers, piers and CAMA-permitted sand fencing are the only exceptions.

On the sound side, the state rule is the estuarine shoreline AEC. That is a band measured landward from normal high water, within which development is regulated. A buffer nearest the water is kept clear of most structures. The width of the band, and the depth of the buffer, vary with the shoreline's classification. The Division of Coastal Management and the town's Building Inspector confirm both, for a given lot, as part of the AEC determination.

The coastal basics (salt in the air, hurricane wind, summer humidity) apply here as they do everywhere on this coast. The case for a different coastal standard makes that argument in full. What sets this stretch of sand apart is how tightly the variation is packed. Three shorelines sit within a handful of blocks, each settling the flood question on its own terms.

On a fifty-foot Carolina Beach lot, the neighbors can stand fifteen feet away.

Side setbacks in the R-1 and R-1B districts are seven and a half feet. On a fifty-foot lot, the neighboring houses can stand as little as fifteen feet apart. That proximity shapes everything about a Carolina Beach lot, from where light enters to what a window looks at. The site analysis exists so that it shapes the design on purpose. Before any drawing starts, the analysis records:

• The lot's flood zone, and the regulatory flood protection elevation that follows from it
• Which shoreline governs the CAMA setback, and whether an AEC determination will be needed
• Where the view corridor toward the water actually falls between the neighbors
• How the sun crosses a lot that is fifty feet wide

On this island, the strand runs roughly north to south. So an ocean-facing lot takes the morning sun on its water side, and the afternoon on the street side. A sound-facing lot gets the reverse.

The analysis is a written document. It is delivered before a single wall is drawn, and kept in the client's project workspace from then on. That matters on a lot this constrained. The decisions that follow it need to trace back to something the parcel showed. That includes the foundation type, the opening protection, and where glass goes and where it doesn't. The design comes out of the site. On a lot this narrow, the site leaves little room for anything else.

A canal lot adds the bulkhead to the list. Its age, its condition and its tie-backs bear on what a foundation near it can do. A foundation plan that ignores an aging bulkhead gets revised mid-permit. The dock, and any davit or lift, come into the layout too, since they fix where the water side of the house wants to open. On any elevated lot, which on this island means a great many of them, the analysis also works out what lives beneath the house. That space is regulated. Parking, storage and access under an elevated floor, in a VE or Coastal A Zone, are breakaway or open construction. They stay clear of anything that would turn the space into a finished room.

The analysis is the first item in the lot read behind the design. It is the file where the survey, the flood-zone reading, and later the elevation certificate, begin to accumulate. It is done to the standard set for every lot. On this ground, the ocean, the sound or the cut is never more than a short walk away.

If the parcel is still a listing, the analysis is most useful before the closing. On Pleasure Island, its answers decide what can be built there. Which zone, which shoreline, how much height the district allows, and how much of the lot can be covered, all come from it.

An elevated house on this island still has to survive the salt.

A raised cottage on posts is the image many people bring to Pleasure Island. It's close to what a lot here still calls for: elevation over open space. Salt reaches every fastener, whether the lot faces the Atlantic or Myrtle Grove Sound. Snow's Cut is the one span every truckload of material has to cross to get there. Tropical Tides designs Carolina Beach homes to pursue FORTIFIED Gold, the highest tier of the Insurance Institute for Business & Home Safety's rating system. An independent evaluator checks the work. Gold requires a continuous load path. A VE or Coastal A lot calls for an elevated pile or pier foundation. There, the path has to run from the roof deck down through the wall framing, across the floor system and into the piles. Every connection along that route gets detailed and inspected. Opening protection on the wall that faces the Atlantic is drawn into the plans before construction starts.

Airtightness works differently over an open understory than over a slab. Our target is sub-1.0 ACH50: fewer than one air change per hour, with the house held at a 50-pascal pressure difference. It is a design target: written into the drawings, carried into construction, and confirmed by blower door before handover. That target addresses the same problem on every lot: controlling where humid coastal air enters the envelope. A pile-supported floor over open or breakaway space has more edges and more penetrations for that air to find. The continuous air barrier has to be traced across the floor-to-wall transition, and around every pile and utility penetration. That transition is where an elevated coastal house most often leaks.

The open understory is also a gift for drying, if the assemblies are chosen for it. Air moving freely under an elevated house lets a floor assembly that has taken on moisture dry downward. An enclosed crawlspace cannot do that. Wall assemblies specified for both how well they shed water and how fast they dry make the most of it. How we plan for moisture starts from one assumption: water will get in somewhere, over the life of a house on the strand. Why moisture planning starts before it shows sets out the reasoning behind it.

Mechanical sizing follows the envelope. A system sized by the square-footage rules of thumb common on the coast tends to run too large for a tight house. It satisfies the thermostat quickly, and shuts off before it has pulled much humidity out of the air. The mechanical design is sized to the actual load the blower-door target produces. Dehumidification is treated as its own job. That is what keeps a Pleasure Island house from feeling damp, on a still August afternoon with the doors shut. Article 5 adds a placement rule the drawings have to answer. In every flood hazard area in town, section 5.124 wants heating, ventilation, air-conditioning, plumbing and electrical equipment at or above the regulatory flood protection elevation. The alternative is equipment designed and installed so the base flood cannot get into it. So on an elevated lot, the air handler and the condensing unit are planned onto a platform, or into the house, from the start. Sub-1.0 ACH50 without stuffy interiors explains the ventilation side of that trade.

Durability on an island this narrow means specifying for salt across the whole lot, ocean face or canal side alike. Connectors, fasteners, railings, exterior equipment and the condensing unit on a canal lot see the same chloride the strand does. The durability choices are made at the drawing stage, so they survive the bidding stage. FORTIFIED Gold and the ACH50 figure are both design targets, checked at the point an independent evaluator and the blower door actually test them.

Under an elevated house the standard stays the same; the load path and the air barrier just have more joints to get right.

The North End is Carolina Beach's canal district.

Canal Drive runs up toward Freeman Park. Its lots back onto Myrtle Grove Sound, near the town's own municipal marina and mooring field. A North End lot is as likely to face a bulkhead and a dock as the ocean. It is also the inlet end of the island. The Division of Coastal Management publishes the long-term erosion rates that set the state's setback factor. For a lot within reach of Carolina Beach Inlet, those rates can push the setback past the default.

The central blocks around the Boardwalk and Carolina Beach Lake hold the town's commercial center, and many of its older houses. The Height Overlay District is drawn to protect the town's traditional, mostly year-round single-family neighborhoods. Whether a given lot in those blocks falls inside it is a question for the zoning map. The answer changes what a three-story design on pilings can do.

South of the center, the Wilmington Beach section runs toward Kure Beach. Hanby Beach sits beyond it, near the town line. Near the south end, the first question is which jurisdiction a parcel is in: Carolina Beach, Kure Beach, or the county. The parcel record and the town's corporate-limits map answer that question. The answer decides which ordinance, which administrator and which permit desk the project belongs to.

On the river side, Carolina Beach State Park and its marina take up much of the Cape Fear frontage. The lots that do exist toward it face a different exposure, and a different flood picture, than the strand across the island. Across Myrtle Grove Sound, the mainland community of Myrtle Grove looks at that water from the opposite shore, under the county's ordinance. Wilmington lies upriver. The rest of the practice's ground, from the Brunswick islands to Pender, is laid out on the service areas overview.

A Canal Drive lot near the municipal marina, a Boardwalk-block teardown, and a parcel within sight of the state park each get the same read. The read covers the shoreline each faces and the district and overlay each falls under. It adds whatever the site analysis turns up, all before a line goes on the page.

Tropical Tides designs and directs Carolina Beach projects from Southport, our home base. The drive is about 42 miles, roughly 65 minutes by road through Wilmington and over the Snow's Cut bridge. The NCDOT Southport-Fort Fisher ferry is the direct alternative, about 35 minutes on the water. From the North End to the Wilmington Beach section, construction itself is carried out by vetted building partners under our direction.
