Cooper is an architectural historian from Ohio who specializes in historic preservation and the nomination process for the National Register of Historic Places.

Takeaways
1
Historic registry requires 50-year age minimum Buildings must be at least 50 years old to qualify for the National Register of Historic Places. The age threshold ensures that nominations focus on structures with genuine historical distance and proven staying power rather than recent construction.
2
Significance comes from architecture or events, not just inhabitants A building's historical value derives from its own architectural merit, cultural impact, or connection to significant historical events—not simply from famous people who lived there. This distinction prevents the registry from becoming cluttered with celebrity homes lacking intrinsic historical importance.
3
Community nomination process democratizes preservation decisions Local communities and architectural historians can submit nominations rather than relying on top-down government designation. This grassroots approach ensures buildings of local significance aren't overlooked by distant authorities.
