Municipal Dock Prohibitions Upheld When Broadly Applicable and Tied to Conservation, Recreation, and Aesthetics

Introduction

Vannata v. Town of Sullivan's Island Board of Zoning Appeals (S.C. Sup. Ct. July 1, 2026) is a nonprecedential memorandum opinion (Rule 268(d)(2), SCACR) affirming the denial of a dock permit and variance request under the Town of Sullivan’s Island Zoning Ordinance.

Paul R. Vannatta and Jennifer S. Vannatta (the “Vannattas”) sought to build a 486-foot dock to reach a 62-foot-wide creek. The ordinance provision at issue, § 21-75(B)(2), barred the project in two ways: (1) a Geographic Restriction prohibiting docks in the RC-2 district between Station 18 and Station 27; and (2) a Dock Length Restriction generally capping docks at 300 feet, with a limited exception (up to 800 feet) that did not apply to the Vannattas’ location.

The Vannattas challenged § 21-75(B)(2) as (i) illegal reverse spot zoning, (ii) a violation of substantive due process, and (iii) a violation of equal protection; alternatively, they claimed entitlement to a variance. The Supreme Court of South Carolina affirmed the circuit court, which had affirmed the Board of Zoning Appeals (BZA).

Summary of the Opinion

  • No reverse spot zoning: The Court held § 21-75(B)(2) did not constitute reverse spot zoning because it was adopted by an affirmative legislative act and applied across a substantial area (about thirty-nine lots), not as a “zoning island” created by later rezoning around a parcel.
  • No substantive due process violation: The restrictions bore a reasonable relationship to legitimate governmental interests (recreation, ecology/environment, and aesthetics), and were not arbitrary or capricious.
  • No equal protection violation: Under rational basis review, the ordinance had plausible policy reasons and the Vannattas did not negate every conceivable basis supporting it.
  • No entitlement to variance: The Vannattas failed to prove “unnecessary hardship” under S.C. Code Ann. § 6-29-800; they purchased the property long after adoption of the restriction and could still make reasonable use of the property.

Analysis

Precedents Cited

1) Deference to municipal zoning and presumption of constitutionality

The Court grounded its approach in the strong presumption that zoning ordinances are valid legislative enactments: Ani Creation, Inc. v. City of Myrtle Beach Bd. of Zoning Appeals (ordinances presumed constitutional; challenger bears a heavy burden), quoting Town of Scranton v. Willoughby and relying on McMaster v. Columbia Bd. of Zoning Appeals for the “no room for reasonable doubt” standard. It also reiterated the “fairly debatable” restraint principle from Rushing v. City of Greenville.

2) Spot zoning and reverse spot zoning framework

The Court treated Ani Creation, Inc. v. City of Myrtle Beach Bd. of Zoning Appeals as the principal modern guide, using it to define reverse spot zoning as a “zoning island” created when surrounding parcels are rezoned and one parcel is left behind, and to emphasize the relevance of comprehensive plan consistency and public welfare (with Knowles v. City of Aiken supplying the two-factor scrutiny when spot zoning is found).

Applying Ani Creation, the Court concluded § 21-75(B)(2) could not be reverse spot zoning because it was not the product of surrounding rezoning; rather, it was enacted affirmatively and applied across a mile of marshland affecting many owners.

3) Substantive due process standard in land-use disputes

For substantive due process, the Court relied on Dunes W. Golf Club, LLC v. Town of Mount Pleasant, quoting McMaster v. Columbia Bd. of Zoning Appeals for the “reasonable relationship to any legitimate interest of government” test, and citing Harbit v. City of Charleston for the requirement of arbitrary and capricious deprivation of a cognizable property interest. Knowles v. City of Aiken was again invoked to cabin courts’ roles in second-guessing planning.

4) Equal protection—rational basis and “steep hill” burden

The Court applied rational basis review per Bibco Corp. v. City of Sumter, emphasizing that the actual motivations of the legislative body are irrelevant and that courts ask what goals it could have been pursuing. It reinforced the challenger’s heavy burden—negating every conceivable basis—from Ani Creation, Inc. v. City of Myrtle Beach Bd. of Zoning Appeals, quoting Bodman v. State.

5) Variances and “unnecessary hardship”

The variance analysis was anchored by Rest. Row Assocs. v. Horry County, which describes variances as exceptional powers sparingly exercised, establishes a presumption favoring zoning validity, and articulates hardship guidelines (including that hardship generally cannot be owner-created and purchasers after enactment cannot complain). The Court also cited Arkay, LLC v. City of Charleston (quoting Gurganious v. City of Beaufort) for deference to local zoning interpretations, and Venture Eng'g for DT LLC v. Horry Cnty. Zoning Bd. of Appeals for the appellate standard aligning with circuit review.

6) Statutory interpretation and “ordinary meaning”

In addressing the undefined term “view corridor,” the Court referenced Pres. Soc'y of Charleston v. S.C. Dep't of Health & Envtl. Control, which quoted Travelscape, LLC v. S.C. Dep't of Rev. on ordinary meaning and reading words in light of statutory purpose, and cited Historic Charleston Found. v. Krawcheck as an example of “view corridor” usage in ordinances.

7) Procedural/briefing consequences

The Court invoked First Sav. Bank v. McLean repeatedly to reject unsupported assertions (e.g., that local regulation cannot be stricter than BCM/Army Corps requirements), treating absence of authority as abandonment.

8) Zoning power and police power limits

The Court cited Bob Jones Univ. v. City of Greenville for the proposition that courts do not zone property and zoning resides in the legislative branch under police powers. It also cited Oxford Fin. Cos. v. Burgess to reject “ignorance of the law” as a basis for hardship.

Legal Reasoning

1) Reverse spot zoning rejected: no “zoning island,” no singling out

The Court’s reverse-spot-zoning holding turned on classification and scale:

  • Classification: Under Ani Creation, Inc. v. City of Myrtle Beach Bd. of Zoning Appeals, reverse spot zoning arises from a failure to rezone a parcel as surrounding parcels are rezoned, creating a “zoning island.” Here, the restriction was enacted by legislative amendment and thus did not match the definition.
  • Scale and evenhandedness: The Geographic Restriction covered about a mile and approximately thirty-nine lots; the Court found the Town did not single out the Vannattas’ property. That some other lots were independently constrained by BCM/Army Corps rules did not negate the ordinance’s uniform application, and the Vannattas identified no authority for such a theory.
  • Comprehensive plan and public welfare: The Court found the restriction consistent with the Comprehensive Plan’s emphasis on long-term preservation and minimal impact on the view corridor, and supported by ordinance findings tied to ecology, flood buffering, recreation, and aesthetics.
  • Edge-of-zone argument rejected: Relying on Ani Creation, the Court held zones must have boundaries and the mere fact that different rules apply across a boundary does not establish a constitutional defect.

2) Substantive due process: legitimate purposes and “reasonable relationship”

Applying Dunes W. Golf Club, LLC v. Town of Mount Pleasant, the Court held the ordinance bore a reasonable relationship to legitimate governmental interests expressly identified in the ordinance and Comprehensive Plan: conservation/ecology, recreation for residents and visitors, and aesthetics (including bridge-view considerations). The Court emphasized that denial of a preferred use is not a due process violation, and it would not act as a “city planner” absent clear injustice.

3) Equal protection: rational basis satisfied

Under Bibco Corp. v. City of Sumter and Ani Creation, Inc. v. City of Myrtle Beach Bd. of Zoning Appeals, the Court found plausible policy reasons for treating the Station 18–27 marsh differently: preserving a dock-free view corridor and protecting a sensitive recreational/conservation area. The Vannattas, who largely recycled their prior arguments, did not negate “every conceivable basis” supporting the ordinance.

4) Variance: no unnecessary hardship and high deference to BZA

The Court applied the statutory criteria for variance under S.C. Code Ann. § 6-29-800 and the hardship guidelines of Rest. Row Assocs. v. Horry County. Key points:

  • Purchased after enactment: The Vannattas bought in 2014, ten years after adoption; under Rest. Row Assocs., that timing undermines a hardship claim.
  • No ignorance defense: Oxford Fin. Cos. v. Burgess foreclosed reliance on lack of deed notice; zoning ordinances are public law.
  • No singular disadvantage / reasonable use remains: The property remained usable as a home with marsh views and access via a public dock.
  • Chain-reaction concern: Echoing Ani Creation, granting one edge-of-zone variance risked compelling similar variances and eroding the restriction.
  • Comparators addressed: A purportedly long dock approved in 2021 fell within the ordinance’s exception (accessed a 207-foot-wide creek), and staff reported no variances had been granted from the restrictions since 2004.

Impact

Although expressly designated as having no precedential value, the opinion is instructive in several practical ways:

  • Reinforces the “Ani Creation” framework for distinguishing reverse spot zoning from boundary-line disputes and for analyzing equal protection in zoning.
  • Signals robust municipal authority to adopt dock restrictions advancing local interests (aesthetics, recreation, conservation), even where state/federal coastal permits exist— particularly where those permits disclaim preemption and require local compliance.
  • Raises the bar for variances in environmentally sensitive districts by emphasizing post-enactment purchase timing, continued reasonable use, and systemic impacts (“chain reaction”).
  • Briefing discipline matters: repeated reliance on First Sav. Bank v. McLean illustrates that unsupported propositions (e.g., implied preemption by coastal permitting) can be treated as abandoned.

In future dock and coastal zoning disputes, litigants should expect courts to focus on the ordinance’s stated findings and comprehensive plan alignment, and to demand clear legal authority for any claim that local zoning must yield to state/federal permitting regimes.

Complex Concepts Simplified

Reverse spot zoning
Not simply “my neighbors can, but I can’t.” In South Carolina’s framing (as applied here), it typically involves a “zoning island” created when surrounding properties are rezoned and one parcel is left with inconsistent zoning. A broad, affirmatively enacted restriction affecting many parcels is unlikely to qualify.
“Fairly debatable”
If reasonable minds could differ about the wisdom of a zoning choice, courts generally defer to the municipality; they correct clear injustices, not planning disagreements.
Substantive due process (land use)
The question is not whether the ordinance is optimal, but whether it is rationally related to a legitimate governmental interest (e.g., ecology, safety, recreation, aesthetics).
Rational basis review (equal protection)
The most deferential constitutional test: the ordinance stands if any plausible legitimate reason supports it. The challenger must disprove every conceivable supporting basis.
Variance / unnecessary hardship
A safety valve, not a second permitting track. The applicant must show exceptional property-specific conditions, a severe restriction on reasonable use, and no substantial detriment to neighbors or the public good—especially difficult where granting one variance would invite many similar requests.

Conclusion

The Supreme Court affirmed Sullivan’s Island’s denial of a dock permit and variance, rejecting claims of reverse spot zoning, substantive due process violation, and equal protection violation. The Court emphasized deference to municipal zoning, the breadth and plan-consistency of the dock-free geographic restriction, and the legitimacy of conservation, recreation, and aesthetics as governmental interests. On the variance claim, the Court applied strict “unnecessary hardship” principles—particularly the rule that post-enactment purchasers generally cannot complain—and credited the Town’s interest in avoiding erosion of the ordinance through boundary-line exceptions.

Even as a nonprecedential memorandum opinion, the decision reflects a clear throughline in South Carolina zoning jurisprudence: where a coastal community legislates with articulated findings, comprehensive plan support, and evenhanded geographic application, constitutional challenges and variance requests face a steep, highly deferential standard of review.
