Sea Cabin Corporation, a South Carolina developer based in Columbia, built Sea Cabins on the Ocean in 1980 on a ~5.95-acre oceanfront tract. The land was acquired from Associated Motels/Hotels, Inc. The project went up in three phases over the course of that year, creating the three-building layout that exists today. Every unit was designed as an identical 1BR/1BA vacation condo with built-in bunk beds in the hallway, a combined living/dining/kitchen area, and a private balcony facing the Atlantic.

The original fishing pier extended roughly 1,000 feet into the ocean — the longest private pier on Isle of Palms.

Sea Cabins was built before South Carolina enacted a statewide building code in 1998 and before Isle of Palms adopted comprehensive flood damage prevention regulations in 1983. The original construction reflects pre-modern coastal wind and flood standards. When major repairs or rebuilds happen, modern code triggers can require upgrades even on a grandfathered structure — if repair costs exceed 50% of the building's appraised value, the structure must meet current flood elevation and construction requirements.

Hurricane Hugo made Category 4 landfall on Isle of Palms on the night of September 21–22, 1989. Storm surge reached roughly 15.5 feet above mean sea level along the front beach. Nearly every structure on the island suffered damage, and more than 200 were destroyed. The stretch of Ocean Boulevard from Sea Cabins to The Windjammer was devastated.

Hugo destroyed the pier's catwalk and most of its pilings. The pier was rebuilt shorter after the storm and currently measures ~575 feet — roughly half its original length. It remains the only private fishing pier on Isle of Palms, shared between Sea Cabins and Oceanside Villas next door.

The three condo buildings survived. Fully engineered coastal buildings of this era typically suffered damage to roofing, wall panels, and cladding rather than main structural systems — consistent with Sea Cabins' continued operation through four decades since the storm.

Three post-Hugo storms have tested the island since: Hurricane Matthew (2016), Tropical Storm Irma (2017), and Hurricane Dorian (2019). None produced Hugo-scale structural damage. Matthew brought meaningful erosion. Irma caused significant sand loss. Dorian's center remained offshore with peak surge around 3–3.5 feet.

The association has invested in several building-wide projects in recent years:

• Roof replacement (2021)
• Pool and kiddie pool resurfacing (2023)
• Gutter replacement (2024)
• New patio railings and deck replacements

These projects address the ongoing reality of maintaining a 45-year-old oceanfront building in a salt-air environment. Request the association's capital budget and reserve status in the resale package.

Every unit at Sea Cabins is the same product: a 1BR/1BA oceanfront condo at ~490 sqft. Price differences come down to floor, renovation quality, and view position relative to the pier and pool.

Active listings cluster in the high $500Ks to low $600Ks. Here is what buyers are paying:

Recent closed sales:

• Unit #314: $697,500 (3rd floor, fully renovated, November 2025)
• Unit #305: $675,000 (3rd floor, fully remodeled from studs, February 2026)
• Unit #238: $669,000 (2nd floor, renovated 2022, July 2025)
• Unit #201: $650,000 (2nd floor, December 2025)
• Unit #128: $550,000 (1st floor, 2024)

Two patterns stand out. Top-floor renovated units command $675K–$700K. Unrenovated or lower-floor units sell for $50K–$100K less. The renovation premium is consistent and large relative to the purchase price.

Over the longer term, appreciation has been substantial. Average prices have risen from ~$558K to ~$655K between 2023 and 2026.

Active listings average ~158 days on market. Sold listings have averaged ~316 days. This is a market where patience is required on both sides of the transaction.

Sea Cabins is one of the simplest condo complexes on the island. Every unit is a 1BR/1BA layout at ~490 sqft interior. The gross area is ~560 sqft including the balcony and utility space.

The layout: enter from the open walkway into a foyer with closet and shelf areas. Built-in bunk beds line the hallway. A utility room houses the water heater and AC handler. The bedroom and bathroom are at one end, with the combined living/dining/kitchen area opening to a private ocean-facing balcony at the other.

Most units sleep 4–6 depending on configuration: a queen bed in the bedroom, the hallway bunks, and a queen sleeper sofa in the living area.

Since every unit has the same footprint, price variation comes from three factors:

• Floor: Top floor (300-series units) consistently sells for $50K–$100K more than first floor (100-series). Second floor (200-series) falls in between.
• Renovation quality: A unit gutted and rebuilt from the studs with luxury plank floors, granite countertops, and modern appliances commands a clear premium over one with original finishes. The gap between "turnkey renovated" and "functional but tired" is $50K–$100K.
• View position: Units with direct pier and pool views or unobstructed ocean sightlines carry a softer premium, but renovation and floor matter more.

End units with private patios occasionally carry a slight premium.

Sea Cabins owners pay a single monthly regime fee with no additional master association or community-level assessment.

~$400/month ($4,800/year) as of 2026. The fee covers:

• Water and sewer
• Cable TV and internet
• Exterior building maintenance
• Common-area insurance (master policy)
• Pool and kiddie pool
• Landscaping and lighting
• Fishing pier maintenance
• On-site management, legal, and accounting
• Pest control

Water, sewer, cable, and internet are not typically included in regime fees at Wild Dunes or other IOP complexes.

• Interior insurance (HO-6 condo owner's policy)
• Flood insurance (individual unit)
• Electricity
• Special assessments (when levied)
• Individual unit repairs and renovation

For a 45-year-old oceanfront building with salt-air exposure and ongoing capital needs, special assessments are a financial reality buyers should budget for. Request the association's assessment history, capital budget, and reserve study in the resale package.

South Carolina has no state-mandated reserve study requirement for condos. A proposed bill (SC Bill 5204, 2025–2026 session) would impose reserve-study requirements, but it has not been enacted as of April 2026. Since Sea Cabins is already non-warrantable, the association faces less external pressure from lender reserve standards than warrantable buildings do. This makes independent due diligence on the reserve picture even more important.

For a non-primary-residence purchase at ~$600K:

Long-held units show tax bills around $3,500–$4,200 because their assessments are frozen at historical purchase prices. A new buyer at ~$600K faces reassessment at current market value. At the 6% non-primary rate with 2025 IOP millage of 236.2 mills, expect an annual bill around ~$8,000–$8,500. The ATI exemption (up to 25% reduction in taxable value) could bring this closer to ~$6,000 if filed timely with the Charleston County Assessor.

Properties rented more than 72 days per year are assessed at the 6% ratio and lose the school-operations exemption — the single largest tax component at 142.5 of the 236.2 total mills. For Sea Cabins, where most units are rented well over 72 days, plan on the 6% rate.

Short-term rentals are the defining feature of Sea Cabins. The vast majority of units are investor-owned vacation rentals. Owner-occupancy is estimated at 0–5%. Island-wide, 55% of all IOP condos hold STR licenses.

Gross rental income varies significantly based on floor, renovation quality, and management approach:

Nightly rates range from ~$155 in the off-season to $500+ during peak summer weeks. Average nightly rates across the complex typically fall in the ~$220–$380 range depending on unit quality and season.

For island-wide context, the median gross STR revenue across all IOP property types was ~$60,000 for the 2024 license year. Sea Cabins 1BR units likely fall below the island-wide median given their smaller size compared to the 3–5BR homes that dominate the high end of the IOP rental market.

IOP seasonal patterns are pronounced: ~74% average occupancy during peak months (March–August) drops to ~43% in the shoulder season (September–February). The ~$309 average daily rate gap between peak and shoulder seasons means the majority of annual income is earned May through August. Oceanfront units like Sea Cabins capture a disproportionate share of peak-season demand.

There is no mandatory rental pool. Owners choose their own management company or self-manage. Multiple managers operate at Sea Cabins, and at least 10 owners self-manage through Airbnb and VRBO.

Management fees typically run 15–30% of gross rental income. The gap between a lean local manager and a full-service national operator can swing NOI by thousands of dollars per year. This is one of the highest-impact financial decisions for a Sea Cabins owner.

At a ~$600K purchase price, modeled NOI ranges:

• $40K gross: NOI of ~$8,000–$15,000 (after taxes, insurance, HOA, management)
• $55K gross: NOI of ~$19,000–$28,000
• $65K gross: NOI of ~$26,000–$36,000

Cap rates span roughly 1–6% depending on gross revenue and management costs. Strong returns require top-tier gross revenue, efficient management, and aggressive booking optimization.

Isle of Palms requires a rental business license. At ~$40,000 gross revenue, the annual license fee runs ~$625.

A 14% combined lodging tax applies to all short-term rentals. This is collected from guests, not deducted from owner proceeds. Professional management companies and major booking platforms generally handle tax collection and remittance.

The City enforces a maximum overnight occupancy of 2 persons per bedroom plus 2 additional. For Sea Cabins 1BR units, that means a maximum of 4 overnight guests.

Isle of Palms does not have an adopted cap on STR permits. Voters rejected a 1,600-permit cap referendum in November 2023.

Rental guests are strictly prohibited from bringing pets. The sole exception is documented ADA service animals. The unauthorized pet fine is $100 per pet, per day, assessed to the unit owner. Confirm current pet rules in the resale package.

Owners may keep one pet per unit. No breed-specific restrictions apply, though dogs that pose a danger to children are prohibited. Pets are not allowed in the pool area, office, laundry room, restrooms, or on the fishing pier.

Sea Cabins is non-warrantable under Fannie Mae guidelines. Standard conventional mortgages through Fannie Mae and Freddie Mac are not available. The building is not on HUD's FHA-approved condominium list and is not on VA's accepted list. No Isle of Palms condo has ever received FHA project approval. The only IOP condo with VA acceptance is Yacht Harbor Villas.

Three characteristics make this building non-warrantable:

1. Investor concentration far exceeds 50%. With an estimated 0–5% owner-occupancy rate, the building exceeds Fannie Mae's threshold by a wide margin.
2. Short-term rental prevalence. The resort-style, high-turnover rental operations push the project toward a "primarily transient" characterization under lender guidelines.
3. Condotel-like characteristics. On-site management, coin-operated laundry, a resort-style pool, and turnkey nightly rentals create a profile that many lenders classify as condotel — even though there is no hotel branding, no mandatory rental pool, and no central front desk.

After the Surfside condo collapse in 2021, lenders increased scrutiny on deferred maintenance and underfunded reserves. For a 45-year-old oceanfront building already outside the conventional lending universe, this broader policy tightening reinforces the importance of reviewing the association's financial health before purchasing.

• Cash. The simplest path. Eliminates the warrantability question entirely.
• Portfolio lenders. Banks that hold loans on their own books rather than selling to the GSEs. Local Charleston-area banks offer portfolio condo financing that supports non-warrantable condos.
• DSCR loans. Programs that qualify the property based on rental income (debt service coverage ratio) rather than borrower income documentation. Non-warrantable condos qualify at up to 80% LTV (20% down) and condotel/STR at up to 75% LTV (25% down).

Typical terms: 20–30% down payment, rates roughly 0.5–1.0% above standard conforming rates. Local portfolio lenders are familiar with Sea Cabins.

FHA Single-Unit Approval exists as a theoretical pathway for individual units in non-approved projects (with a max 10% FHA concentration for projects with 10+ units), but the building's investor concentration and STR profile make approval unlikely.

The building sits in FEMA Zone AE with a Base Flood Elevation (BFE) of 10 feet. The adjacent VE (coastal high hazard) zone with wave action begins roughly 200 feet east of the building, on the beach side. The buildings themselves are entirely within AE.

Sea Cabins is eligible for federal flood insurance through the National Flood Insurance Program (NFIP). Isle of Palms was heavily developed before the Coastal Barrier Resources Act was enacted in 1982, and Sea Cabins was built in 1980 — the complex falls outside any Coastal Barrier Resources System unit.

Isle of Palms' local flood standards require a Design Flood Elevation of BFE + 1 foot, or 13 feet above mean sea level — whichever is higher. This exceeds the FEMA minimum and is tied to the City's participation in the Community Rating System.

Buyers should review the current FIRM panel for their specific parcel.

The regime fee includes common-area insurance covering the building exterior and common elements. Request the insurance declarations in the resale package — the scope, deductible structure, and whether master flood coverage is included are critical details. Named-storm deductibles on coastal master policies typically run 2–5% of insured value.

Owners need an HO-6 policy (condo owner's policy) covering interior improvements, personal property, and liability, plus:

• Wind/hail coverage: Standard homeowner's policies in coastal South Carolina routinely exclude wind and hail damage. If the private market excludes wind/hail, the South Carolina Wind and Hail Underwriting Association (the Wind Pool) is available as a carrier of last resort on Isle of Palms. The Wind Pool approved a 21.3% base rate increase in June 2024 and another 8% increase effective February 2026.
• Flood insurance: NFIP or private flood. Isle of Palms participates in FEMA's Community Rating System, providing a 25% discount on NFIP premiums. Under Risk Rating 2.0, premiums are property-specific based on first-floor height, distance to coast, and replacement cost. Private flood alternatives may beat NFIP rates for upper-floor units. Non-primary-residence owners pay a $250/year HFIAA surcharge on top of their NFIP premium (versus $25 for primary residents).
• Loss assessment coverage: Recommended at $25,000–$50,000. This protects against post-storm special assessments when the master policy's named-storm deductible is passed to individual owners. The additional premium is typically ~$50/year.

Estimated individual insurance costs: ~$1,700–$3,900/year for the full bundle (HO-6, wind/hail, flood, loss assessment). Actual costs vary based on floor level, deductible structure, and carrier.

For upper-floor units with living spaces well above the 10 ft BFE, individual flood contents coverage is optional rather than essential — the primary exposure scenario is catastrophic storm surge exceeding the building's elevated floor levels.

In a hurricane, a single event commonly triggers both the wind/hail deductible (on the homeowner's/wind policy) and the flood deductible (on the flood policy). Add in a master-policy named-storm deductible that gets passed to owners via special assessment, and a single storm can generate five-figure out-of-pocket exposure. Budget accordingly.

• Oceanfront pool: Resort-style pool directly on the ocean side, plus a kiddie pool (resurfaced 2023)
• Private fishing pier: ~575 feet, the only private pier on Isle of Palms, shared with Oceanside Villas residents
• Beach access: Private boardwalk directly over the dunes, plus gated beach access
• Parking: Free HOA-owned parking spaces
• Laundry: On-site coin-operated laundry facilities (shared with Oceanside Villas)
• Outdoor space: Picnic area with common grilling stations
• Seasonal rentals: Beach chair and umbrella rentals available on the beach
• Adjacent to: Isle of Palms County Park

The pier is one of Sea Cabins' most distinctive amenities. It provides fishing access without needing a boat and is available exclusively to Sea Cabins and Oceanside Villas owners and guests.

Individual balcony grilling may be restricted under fire code provisions that prohibit charcoal, propane, and gas grills on combustible balconies or within 10 feet of combustible construction in multi-family buildings. The common grilling area is the designated alternative.

Sea Cabins sits on Isle of Palms' front beach, immediately adjacent to the Isle of Palms County Park. This is the non-resort section of the island, outside Wild Dunes' gates. The complex is within walking distance of the IOP commercial district along Palm Boulevard.

• Acme Lowcountry Kitchen
• Long Island Cafe
• Sea Biscuit Cafe

• Downtown Charleston: ~17 miles, ~30 minutes
• Charleston International Airport: ~17 miles, ~25 minutes
• Mount Pleasant: ~4 miles
• Sullivan's Island: ~2 miles

The typical Sea Cabins buyer is an investor purchasing a vacation rental property, not a primary residence. The building is almost entirely STR-focused. A secondary buyer profile is the second-home owner who wants oceanfront access at IOP's lowest price point and plans to rent the unit when not using it personally.

Cash buyers and investors comfortable with portfolio or DSCR financing are the natural audience. Anyone requiring conventional financing or FHA/VA should look elsewhere.

• You want the most affordable oceanfront entry on Isle of Palms. At ~$570K–$700K for a 1BR, Sea Cabins is the lowest-priced direct oceanfront product on the island.
• You want a turnkey vacation rental with proven demand. The STR infrastructure is mature — multiple management companies, strong booking history, and established rental income benchmarks.
• You can pay cash or navigate non-warrantable financing. The building's non-warrantable status actually reduces competition from conventional buyers and keeps prices lower than they would otherwise be.

• You need FHA, VA, or standard conventional financing. Sea Cabins is non-warrantable and not approved for government-backed loans.
• You want more than one bedroom. Every unit is a 1BR/1BA at ~490 sqft. If you need more space, neighboring Oceanside Villas offers 2BR units at ~960 sqft, and Wild Dunes complexes offer larger layouts.
• You want newer construction or elevator access. Sea Cabins was built in 1980, before South Carolina's statewide building code. All three buildings are walk-up only.

The regime fee is ~$400/month. The all-in annual cost is closer to ~$15,000–$17,000 when you add property taxes (new-buyer basis), insurance, and the regime fee together. That is before mortgage, utilities, unit maintenance, or management fees.

For investors running the numbers, the building's economics work best for buyers who:

1. Purchase in cash or with minimal leverage
2. Use an efficient management structure (closer to 15% commission than 30%)
3. Invest in a quality renovation to command top-floor pricing
4. Maintain a personal capital reserve of $15,000–$35,000 for special assessments and post-storm deductible exposure

For a 1980 oceanfront building, the capital reserve line item belongs in every buyer's pro forma.

Sea Cabins and Oceanside Villas are frequently confused. They are distinct, separately managed complexes with different HOAs that share reciprocal access to certain amenities (the fishing pier, laundry facilities).

Sea Cabins' niche is clear: the most affordable oceanfront on Isle of Palms, without resort gates, golf courses, or community association layers. The tradeoff is a 45-year-old building, non-warrantable financing, and 1BR-only inventory. Port O'Call is the closest alternative if you want gated Wild Dunes resort amenities at a similar price point but with higher fees and resort-level transfer costs. If you need more space, Oceanside Villas next door offers 2BR units at a higher price.

What are the HOA fees at Sea Cabins on the Ocean?

The regime fee is ~$400/month ($4,800/year) as of 2026, covering water, sewer, cable TV, internet, exterior maintenance, common-area insurance, pool upkeep, landscaping, and management. There are no additional master association fees — Sea Cabins is not part of Wild Dunes or any umbrella community. Verify the current fee and what it covers in the resale package.

Can you rent Sea Cabins on Airbnb or VRBO?

Yes. Short-term rentals are the dominant use — the vast majority of units are active vacation rentals. There is no mandatory rental pool. Owners choose their own management company or self-manage through Airbnb and VRBO. Isle of Palms requires an STR license and charges a 14% combined lodging tax. There is no adopted cap on STR permits on Isle of Palms as of 2026.

What flood zone is Sea Cabins in?

FEMA Zone AE with a Base Flood Elevation of 10 feet. The adjacent VE (coastal high hazard) zone begins roughly 200 feet oceanward of the building footprint, but the buildings themselves sit entirely in AE. Isle of Palms participates in FEMA's Community Rating System, providing a 25% discount on NFIP flood insurance premiums.

What is the average price per square foot at Sea Cabins?

Recent sales average ~$1,340/sqft. Active listings are asking ~$1,210/sqft. Top-floor renovated units command the highest premiums — one sold for ~$1,420/sqft in late 2025. First-floor units typically list in the high $500Ks to $600K range.

Is Sea Cabins FHA or VA approved?

No. Sea Cabins is not on HUD's FHA-approved condominium list and is not on VA's accepted list. The building's high investor concentration and short-term rental prevalence make it non-warrantable under Fannie Mae guidelines. Buyers typically use cash, portfolio lenders, or DSCR loan products with 20–30% down payments. FHA Single-Unit Approval exists as a theoretical pathway but is unlikely to succeed given the building's profile.

Are pets allowed at Sea Cabins on the Ocean?

Owners may keep one pet per unit with no breed-specific restrictions. Rental guests are strictly prohibited from bringing pets, with the sole exception of documented ADA service animals. The $100/day unauthorized pet fine is assessed to the unit owner. Confirm current pet rules in the resale package.
