Reserve Studies and Aging Coastal Infrastructure in the Carolinas

Summary

Across North and South Carolina, many community associations are reaching a point where major building components are simply getting old and requiring replacement. This is actually expected and predictable in most cases from a Reserve planning standpoint, but can catch residents by surprise. Major replacement cycles for major equipment and exterior components occur at or before the 20-year mark, so those costly replacement projects have now begun for most of those properties!

For coastal condominiums and homeowners associations, this challenge is amplified by salt air corrosion, increased exposure to extreme weather events (such as hurricanes), consistently high humidity, and accelerated wear on building systems. For that reason, a professionally prepared Reserve Study in the Carolinas (or any coastal region, really) is one of the most important tools associations can use to manage long-term capital repairs and avoid special assessments!

Why the Coast Is Different

Salt Air: It's not just a nuisance for most assets on property, it is corrosive and accelerates deterioration. You'll see quicker degradation levels within (but not limited to):

• Structural and Reinforcing Steel

• Balcony and Stair Connections/Hardware

• Entry & Utility Doors

• Railings and Exposed Fasteners

• HVAC Units

• Major Exterior/Exposed Mechanical Equipment

  
  

Extreme Weather: High winds, wind-driven rain, and hurricanes shorten the life of:

• Paint, Sealants, and Other Waterproofing Systems

• Roofing Systems

• Siding and Cladding

• Windows

  
  

Even concrete and pavement suffer. Salt and moisture intrusion contribute to cracking, spalling, and premature failure. The result is straightforward:

Components in coastal communities often do not last as long as they would at inland properties, nor do they often meet the manufacturer’s published “average useful life” (unless that life assumes coastal application).

Where We See the Biggest Funding Gaps

In many coastal associations, a Reserve Study was never obtained, or a Reserve Study that was completed years ago did not fully account for environmental exposure. In addition, major unexpected cost increases have occurred over the past several years that couldn't have been predicted in the prior decade (such as COVID-19, hurricanes, etc.). The major gaps show up today in a few areas:

Elevated Structures: Balconies and walkways are critical traffic and safety components. Whether they are present at a two-story apartment-style condominium or a 15-story timeshare resort, waterproofing membranes will deteriorate over time and leave the underlying concrete (and hardware) exposed to the elements. Maintenance projects (such as re-coating) can protect those elements and prolong the life of the waterproofing system as a whole. When steel connectors begin to corrode or embedded reinforcement deteriorates, repairs become more complex and more expensive at an exponential rate.

Exterior Envelope: Paint, sealants, expansion joints, siding systems, and stucco require consistent maintenance cycles. Delays allow moisture intrusion, which can lead to major structural repair needs instead of minor, surface-level maintenance.

Mechanical Systems: Exterior condensers, rooftop units, exhaust fans, heat exchangers, pool equipment, and other exposed systems frequently experience shortened lifespans near the ocean.

Roofing: Fasteners corrode. Shingles on your three-story townhome building lose adhesion. Flat roofing membranes at the top of mid-rise or high-rise condo buildings fatigue. Storm damage compounds wear. Replacement timing often arrives sooner than expected.

The Financial Risk of Waiting

When reserve funding does not keep pace with deterioration, associations are forced into reactive decisions:

• Delayed Maintenance (Which Amplifies and Escalates Other Issues)

• Emergency Projects

• Special assessments

• Borrowing/Loans

  
  

In coastal markets where insurance premiums are already high and underwriting standards are tightening, visible deferred maintenance can create additional financial strain. Underfunded reserves are not just a bookkeeping issue. They affect property values, insurability, and owner confidence.

What a Coastal Reserve Study Should Reflect

A Reserve Study for a coastal association should be grounded in real conditions, not "generic" industry expectations. That means:

• On-site Evaluation of Major Components

• Adjusted Useful Life Estimates Based on Environmental Exposure

• Adjusted Remaining Useful Life Estimates Based on Exposure & Maintenance/Repair History

• Accurate, Current Replacement Cost Data

• A Funding Plan Reflecting Realistic Project Timing

  
  

Periodic updates (typically once every three years) are particularly important along the coast. Construction costs, insurance pressures, and storm activity all influence long-term planning heavily from year-to-year.

Requirements in North Carolina & South Carolina?

At this time, neither North Carolina nor South Carolina requires mandatory Reserve Studies or minimum reserve funding levels. You can check out the Community Associations Institute's summary for each state here.

However, the regulatory landscape is evolving nationwide. States such as California, Florida, New Jersey, and Washington, have all implemented Reserve Study requirements to some degree. In this region, Tennessee has already implemented statutory requirements for Reserve Studies and disclosures for certain associations, signaling a broader shift toward stronger financial oversight. Even in the absence of state mandates in the Carolinas, proactive reserve planning will position associations ahead of potential legislative changes. Getting ahead of the curve protects homeowners, strengthens financial stability, and reduces the risk of sudden compliance pressures if similar requirements are introduced in the future.

Conclusion

Many coastal Carolina communities are now 20 to 40+ years old. The major replacement cycles for many components at each of those properties have begun. Roofing, paving, painting, structural components, and mechanical systems will not last indefinitely, especially in a salt-heavy environment.

Associations that align their reserve funding with actual deterioration patterns will remain stable and predictable. Those who delay will eventually pay an exponentially higher cost than those who took the proactive approach.

A Reserve Study does not prevent aging. It ensures that when aging shows up, the community is financially prepared to address it!
