Should homeowners be permitted to add modern structures to historic properties in your area?

The Evanston Preservation Commission has unanimously approved plans for an accessory dwelling unit (ADU) at a local mid-century landmark home. The project will add a detached living space to the property located at 3433 Clifford St.

Why it matters

This approval allows for residential expansion on a historically significant property while maintaining required site aesthetics. It highlights how homeowners of local landmarks can navigate the preservation process to add functional living space to their lots.

The project at 3433 Clifford St includes a seven-foot rear yard setback and a five-foot side yard setback. The main structure was originally built in 1951 and designed by architect Barry Byrne.

The Home Front

This project reflects a broader trend of integrating ADUs into historic districts through careful design review. Such approvals follow national preservation standards for ensuring new construction remains compatible with existing historic architecture.

Homeowners planning similar projects on landmarked properties should confirm all setback requirements with the city before finalizing blueprints. Consider scheduling a pre-application consultation with your local preservation board to discuss how to keep additions sympathetic to your original 1951 architecture.

The takeaway

Historic designation requires balancing modern housing needs with original site integrity. Before starting any major external project, ensure you review your property's specific historic survey to identify protected architectural features.
