Historic Resources Inventory Disclaimer:
All addresses shown are not historic. To identify historic properties, you'll want to check if the property is designated as a City Landmark or Structure of Merit or listed as a contributor to a Historic District or Neighborhood Conservation Area.
The City maintains an active program to designate historic resources. The Cultural Resources Ordinance (Title 20) recognizes four types of local designation:
- City Landmark - A cultural resources of the highest order of importance
- Structure of Merit - A cultural resource that is important, but a lesser level of significance or integrity than a City Landmark
- Historic District - A geographically defined area within the City that has a significant concentration of cultural resources that represent themes important in local history.
- Neighborhood Conservation Area (NCA) - Similar to a historic district, but with resources of somewhat lesser significance and/or with a lesser concentration of resources.
As part of the goals and policies of the Historic Preservation Element of the General Plan, Riverside also maintains an active and systematic program to survey cultural resources citywide. Surveys are completed for a variety of reasons. They tell us what properties are architecturally and historically significant and what properties are eligible for designation. They also facilitate environmental review processes, promote heritage tourism initiatives, and serve as the basis for establishing historic districts and developing design guidelines. Finally, surveys foster civic and neighborhood pride and further knowledge of, and appreciation for, Riverside’s cultural heritage. Information on properties that have been surveyed can be accessed from the Historic Resources Inventory.
