New London County Homeowners Must Navigate Enhanced Wind Resistance Standards for Vinyl Siding in 2024

Connecticut’s coastal communities face increasingly stringent building code requirements as 2024 brings enhanced wind resistance standards that directly impact vinyl siding installations. For homeowners in New London County, understanding these updated requirements is crucial for both new construction and renovation projects.

Understanding Connecticut’s Current Building Code Framework

The 2022 Connecticut State Building Code (CSBC) is based on the International Code Council’s widely-adopted 2021 International Codes and references the ICC A117.1-2017 standard for accessibility. It applies to projects with permit applications filed from October 1, 2022. This comprehensive code establishes the foundation for all construction requirements throughout the state, including specific provisions for coastal areas.

Vinyl siding shall be certified and labeled as conforming to the requirements of ASTM D3679 by an approved quality control agency. This certification ensures that all vinyl siding products meet rigorous industry standards for durability and performance.

Wind Load Requirements for Coastal Properties

The most significant change affecting New London County residents involves enhanced wind load calculations. Vinyl siding and insulated vinyl siding conforming to the requirements of this section and complying with ASTM D3679 and ASTM D7793, respectively, shall be permitted on exterior walls where the design wind pressure determined in accordance with Section 1609 does not exceed 30 pounds per square foot (1.44 kN/m2). Where the design wind pressure exceeds 30 pounds per square foot (1.44 kN/m2), tests or calculations indicating compliance with Chapter 16 shall be submitted.

This threshold is particularly important for coastal properties, where wind pressures often exceed the standard 30 psf limit. Properties exceeding this threshold must provide additional engineering documentation to demonstrate compliance with structural requirements.

Installation Standards and Weather Protection

Siding requirements, on the other hand, primarily focus on durability, water resistance, and insulation. Depending on the type of siding used, there may be specific requirements for how it should be installed and maintained. For example, vinyl siding should be installed over a weather-resistant barrier to prevent water intrusion.

The updated codes emphasize proper installation techniques that ensure long-term performance in Connecticut’s challenging coastal environment. The siding shall be applied over sheathing or materials listed in Section 2304.6. Siding shall be applied to conform to the water-resistive barrier requirements in Section 1402. Siding and accessories shall be installed in accordance with the approved manufacturer’s instructions.

Enhanced Fastening Requirements

Recent updates to building codes have introduced more specific fastening requirements for vinyl siding installations. The 2024 IRC now codifies key vinyl siding installation practices. New sections added in the FBCB and FBCR codifying key vinyl siding installation practices. These provisions specifically require manufacturer-approved starter strips at the initial course and utility trim under windows and other nail hem cut areas of the siding to ensure proper attachment and wind performance (RB230-22).

Unless otherwise specified in the approved manufacturer’s instructions, nails used to fasten the siding and accessories shall be corrosion resistant and have not less than a 0.313-inch (7.9 mm) head diameter and 1/8-inch (3.18 mm) shank diameter. Unless specified otherwise by the approved manufacturer’s instructions, fasteners shall be installed in the middle third of the slots of the nail hem and spacing between fasteners shall be not greater than 16 inches (406 mm) for horizontal siding and 12 inches (305 mm) for vertical siding.

Compliance and Permitting Considerations

The Connecticut State Building Code (CSBC) applies to all newly-constructed buildings, as well as those undergoing alterations, additions, or changes of use. In conjunction with the Codes and Standards Committee, the Office of the State Building Inspector (OSBI) establishes the building, electrical, mechanical, plumbing, accessibility, and energy code requirements of the CSBC, necessary to promote the health and safety of the people of Connecticut.

Homeowners should be aware that permit requirements may vary by municipality within New London County. Accurate and timely submission of permits is crucial for quick approvals on roofing projects in Central Connecticut due to the high demand for new roof replacements.

Looking Ahead: Future Code Updates

Code adoption is always happening. It takes a lot of time and work. Connecticut continues to evaluate and update building codes to address evolving challenges, particularly those related to climate resilience and extreme weather events.

The enhanced wind resistance standards represent just one aspect of Connecticut’s comprehensive approach to building safety. As coastal communities face increasing weather-related challenges, these updated requirements ensure that vinyl siding installations provide the durability and protection homeowners need.

For New London County residents planning vinyl siding projects in 2024, understanding these enhanced building code requirements is essential for ensuring compliance, safety, and long-term performance.
