Custom home builder in Carolina Beach, North Carolina.

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

Carolina Beach takes up the northern end of Pleasure Island. The ground was a peninsula until Snow's Cut, the Intracoastal Waterway channel between the Cape Fear River and Myrtle Grove Sound, was dredged in 1929 and 1930 and made it an island. One road bridge crosses the cut, carrying US 421, and apart from the ferry landing at Fort Fisher on the island's far end it 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, with Carolina Beach Lake a couple of blocks off the ocean. The north tip is Freeman Park, the drive-on beach that runs out toward Carolina Beach Inlet. The inlet is man-made: the Army Corps of Engineers opened it in 1952 and dredges it regularly, and 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, a fifty-foot rise that 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 inside CAMA's ocean hazard area and, on the flood map, inside 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, so a lot of new construction here replaces an older raised cottage on a fifty-by-one-hundred lot, and what goes up has to satisfy a zoning district, a flood elevation and a wind standard the original never knew. New homes here are custom homes shaped by a lot that already has a history.

A Carolina Beach house can cover forty percent of its lot.

Carolina Beach is an incorporated town and governs its own ground under a Unified Development Ordinance adopted in July 2024 and amended since, most recently in August 2025; the version in force on the day an application goes in is the one that governs. A lot inside the town limits is zoned by the town, and the building permit comes from New Hanover County Building Safety, the same department that issues building and trade permits for the unincorporated county.

Several offices carry a residential project through. The UDO Administrator, designated by the town manager, interprets and enforces the ordinance; questions of interpretation go there first, and appeals go 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. The UDO names the town Building Inspector as the designated official for CAMA minor development permits, with a duty to decide in writing, before any building permit issues, whether a parcel lies inside a CAMA Area of Environmental Concern. Once that determination clears, the building permit itself, and every trade inspection behind it, is issued by New Hanover County Building Safety through its COAST portal.

A single-family house that needs a CAMA permit usually needs a minor permit, and local governments review, issue and administer those to the Coastal Resources Commission's standards under contract with the Division of Coastal Management; the Division's own guidance is that a complete application should see a minor permit within twenty-five days. On an island where the ocean hazard and estuarine shoreline AECs between them touch much of the town's shoreline, that review runs alongside the zoning review, and our six-phase process builds it into the permit path.

Ultimate design wind speed

150 mph east of US 17 (2018 NC Residential Code, Table R301.2(4), footnote h)

Article 3 describes four residential districts that carry single-family houses. R-1 allows single- and two-family houses; R-1B, R-2 and R-3 are single-family, stepping down in density. Table 3.3 gives R-1 and R-1B the same footprint rules: a 5,000-square-foot minimum lot, fifty feet of width, a twenty-foot front setback, ten at the rear and seven and a half at each side, dimensions that 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, and R-3 for 12,000 square feet and eighty feet. All four 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 ceiling on structure height everywhere outside a conditional-zoning proposal in the central business district, and lower caps apply below it: the table holds R-2 to forty-five feet and R-3 to forty, and a Height Overlay District, drawn on the official zoning map to protect the town's traditional, mostly year-round neighborhoods, holds lots inside it to 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 is in, and whether the overlay reaches it, is read from the zoning map with the UDO Administrator.

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

Dredging Snow's Cut in 1929 and 1930 put the Atlantic on one edge of Pleasure Island and Myrtle Grove Sound, or the cut itself, on the other, 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) holds New Hanover County to 140 mph west of US 17 and 150 mph east of it, under footnote h, and Pleasure Island sits entirely on the 150 mph side. Exposure category is left to the design professional, since it turns on what stands between a given lot and open water, and the flood zone 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, and a registered engineer or architect certifies 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 (LiMWA) line; the Coastal A Zone is the band between it and the VE zone, and it is usually not labeled as a zone on the map. The UDO holds that ground to the same elevation and breakaway-wall standard as VE itself, and 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, and catching that distinction is the site analysis's job.

Canal and sound lots along Myrtle Grove Sound often carry an AE designation instead, and the measurement changes with it: in an AE zone the reference level is the top of the lowest floor, where VE measures to the bottom of the lowest beam. The elevation itself is defined the same way everywhere in town. Where a base flood elevation has been established, the regulatory flood protection elevation is that BFE plus two feet of freeboard; where none has, it 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, checked against the lot.

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

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)

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 and 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 and rises through the size bands to 180 feet for the very largest structures, and where the Division of Coastal Management's long-term erosion rate for a stretch of shoreline is higher, so is the factor and the setback. 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, 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, a band measured landward from normal high water within which development is regulated and 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, and 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 everywhere on this coast, and 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 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, so 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, and 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, and 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, and a sound-facing lot the reverse.

The document is written, 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 because the decisions that follow it (the foundation type, the opening protection, where glass goes and where it doesn't) need to trace back to something the parcel showed. The design comes out of the site, and 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, and 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, because that space is regulated: parking, storage and access under an elevated floor in a VE or Coastal A Zone are breakaway or open construction, kept clear of anything that would turn it into a finished room.

The analysis is the first item in the lot read behind the design, and it is the file in which the survey, the flood-zone reading and, once one exists, the elevation certificate begin to accumulate. It is done to the standard set for every lot, on ground where 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, since its answers on Pleasure Island (which zone, which shoreline, how much height the district allows, how much of the lot can be covered) decide what can be built there.

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, and it's close to what a lot here still calls for: elevation over open space, salt reaching every fastener whether the lot faces the Atlantic or Myrtle Grove Sound, and Snow's Cut as 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, with the designation verified independently by IBHS. On an elevated pile or pier foundation, which is what a VE or Coastal A lot calls for, the continuous load path that Gold requires has to run from the roof deck down through the wall framing, across the floor system and into the piles, with every connection along that route 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, and it is a design target: written into the drawings, carried into construction, and confirmed by blower door before handover. The target addresses the same problem on every lot, controlling where humid coastal air enters the envelope, but 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, and 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, which an enclosed crawlspace cannot do, and 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 the assumption that water will get in somewhere over the life of a house on the strand; the reasoning behind it is set out in why moisture planning starts before it shows.

Mechanical sizing follows the envelope. A system sized by the square-footage rules of thumb common on the coast tends to be 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 of the envelope the blower-door target produces, with dehumidification treated as its own job, which 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, or 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, and 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, verified at the point IBHS and the blower door actually check them.

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

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, and the new home we design for it has to fit a 5,000-square-foot parcel under a forty-percent lot-coverage cap and a sixty-five-percent impervious cap, inside the setbacks, under the height its district and any overlay allow, at or above the regulatory flood protection elevation, and behind whichever CAMA line applies. Each of those constraints is common on its own. Together, on fifty feet of width, they are the design problem, and 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 before anything else. The town sets that threshold at forty-nine percent: when repair, reconstruction, addition or other improvement costs forty-nine percent or more of the structure's pre-improvement market value within any one-year period, the whole structure has to be brought up to the current regulatory flood protection elevation from top to bottom, whatever portion the renovation actually touched. That's one point below the fifty percent the federal flood insurance rules set as the minimum. For a pre-FIRM cottage it often turns a renovation into a decision between a scope kept deliberately under the line and a project that lifts the house, in which case the elevation, the new foundation and the load path are designed together.

Whether an ADU is feasible in Carolina Beach depends on the UDO as published. The definitions, as amended in August 2025, recognize an accessory apartment as a self-contained dwelling unit inside an existing structure for a single family, and the published ordinance carries no separate definition of, or authority for, a detached accessory dwelling. Section 3.6 then limits a residential lot to one customary accessory building beyond a short list of exemptions, caps it at a quarter of the principal building's lot coverage and fifteen feet in height, keeps it out of the front and side yards and five feet off the rear line, and 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 put the question to the UDO Administrator, who confirms what a specific parcel may build. Where an accessory apartment built into the existing structure is what fits the lot, it's held to the same envelope and moisture standard as the house around it.

Two more ordinances catch teardowns on narrow lots. The town's landscape ordinance applies to regulated vegetation across the whole municipal limits, dune and inland lots alike, and 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 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 is stormwater. A town stormwater drainage permit comes in two tiers, one without an engineered plan for clearing to bare soil or adding impervious surface, and one with an engineered drainage plan for grading, filling, any building permit that increases impervious surface, or a site with a history of flooding or erosion, and no building permit issues until the town manager or designee certifies the approach. Alongside it sits the impervious-coverage plan: required once a project adds more than 325 square feet of impervious area, and prepared by a licensed surveyor, architect, landscape architect or engineer once the addition reaches 500 square feet. On a lot already near the sixty-five-percent cap, that plan counts the driveway, the walks and the equipment pad before anyone has grown attached to them.

The North End is Carolina Beach's canal district.

Canal Drive runs up toward Freeman Park with lots that back onto Myrtle Grove Sound near the town's own municipal marina and mooring field, so 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, and 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, and 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, with Hanby Beach 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 it, and 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, and the lots that do exist toward it have a different exposure and a different flood picture from the strand across the island. Across Myrtle Grove Sound, the mainland community of Myrtle Grove looks at the same water from the opposite shore under the county's ordinance, and 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 shoreline it faces, the district and overlay it falls under, and whatever the site analysis turns up before a line goes on the page.
