About UNION LEAGUE CLUBHOUSE FOUNDATION

The Union League Clubhouse Foundation is a donor-facing 501(c)(3) public charity created to support preservation and capital work for the Union League Clubhouse. Established in late 2013, the Foundation provides a tax-deductible vehicle for members and friends to fund restoration and long-term maintenance of the Clubhouse.

The Foundation’s activities over the last 2–3 years have focused on major exterior and code-compliance projects (including Local Law 11 work and a multi-year windows initiative), with documented contributions to specific restoration projects and recorded grant/contribution activity on recent Form 990 filings. The organization’s EIN (45-5282023) has been verified against public nonprofit records and the Club’s official materials.

Notable achievements

Major Windows Restoration Support

Provided $1.8 million in support for the Clubhouse windows project (including approximately $800,000 donated in 2022), underwriting replacement and restoration work to preserve the building’s historic fenestration.

Local Law 11 / Façade Work

Committed significant funding to Local Law 11 façade and exterior safety work across 2022–2023 (including approximately $350,000 in Foundation funds), helping offset the Club’s larger capital expenditures for masonry and safety compliance.

Exterior Conservation and Access Improvements

Funded targeted exterior conservation projects and access improvements, including contribution toward a new Park Avenue door and 2021 wrought-iron fence refurbishment (project funding in the mid-six-figure range across recent years).
