Preservation Online

Welcome to Preservation Online! Preservation Online is where old buildings meet modern technology to bring you historic property information conveniently. Preservation Online is a portal to an interactive map application that allows you to access parcel-based historic resource data through the City of Orange Internet site.

Preservation Online is an extension of the City’s commitment to provide excellent customer service to the Orange community. The purpose of Preservation Online is to provide the public with easy access to hands-on information, answering questions about historic property characteristics.

The Planning Division of the Community Development Department, in collaboration with the Public Works Geographic Information Systems (GIS) section, is committed to providing the public with the most up-to-date historic resources information in an easy and efficient manner.

The information made available on Preservation Online reflects the content of the City's 2010 Historic Resources Inventory.

***Preservation Online is also available and featured at the Main Orange Public Library Local History Room terminals.***
