Hercules, CA Historic Preservation: Historic-Cultural Monuments (2026)

Chapter 13-20 of the Hercules Municipal Code establishes the H historic overlay district to identify areas and buildings that possess a unique historical character and to preserve, enhance, promote and expand their cultural and historical identities through review of exterior architectural features. An H district can be initiated by the property owners' consent, a Planning Commission motion, or a City Council motion, but it must be layered over an existing zoning district rather than stand alone, and its boundaries need not match those of the underlying district.

200: that the area or buildings have a unique historical character and identity, and that the historical character, identity and environment would be preserved and enhanced to the benefit of the area and the City by applying the H district's regulations and review procedures. 300, only structures of similar historical and cultural significance may be erected or relocated there, and any exterior alteration, enlargement, rebuilding or demolition needs prior approval from the City Council or the Historical Architectural Review Board. The Planning Commission holds a public hearing on any proposed H district within 30 to 60 days after the application is complete, with mailed notice to owners within 300 feet and posted/published notice at least 10 days ahead, then forwards a recommendation to the City Council, which holds its own hearing and can approve, deny or condition the designation.
