Editor's note— Ord. No. 1699, § 4, adopted March 11, 2025, amended the title of Ch. 2.20 to read as herein set out. The former Ch. 2.20 title pertained to historical preservation commission.

2.20.010 - Creation—Purpose and intent.

The city finds, determines and declares:

A. That the state legislature of California, pursuant to Government Code Section 37361, has recognized the value of identifying protecting and preserving places buildings, structures and other objects of historical, aesthetic and cultural importance and has empowered cities to adopt regulations and incentives for the protection, enhancement, perpetuation and use of such places, buildings, structures and other objects.

B. That the city possesses many distinctive places, structures, neighborhoods, and urban design features (all herein referred to as "resources") that enhance its value as an attractive and delightful community in which to live and work.

C. That certain of these resources are of cultural, aesthetic or historical significance and value because of age, architectural style, aesthetic appeal or association with local history.

D. That by preserving these resources Rialto shall contribute to the livability and beauty of the community, stimulate economic revitalization, improve property values in the city, foster architectural creativity, increase neighborhood stability and conservation, foster public appreciation of and civic pride in the beauty of the city and the accomplishments of its past, reinforce the distinctive character of the community, add to the community's understanding of its history and connection with the life and values of the past, and ensure that Rialto's cultural, historical and architectural heritage will be imparted to future generations.

E. That shifts in population and in the economy changes in the way people live and changes in land use threaten to destroy these irreplaceable and desirable resources. Construction and alterations of inferior quality and appearance are also a threat to these resources.

F. That the adoption of reasonable and fair regulations is necessary as a means of recognition, documentation, preservation and maintenance of resources of cultural, aesthetic, or historical significance. Such regulation serves as a means to integrate the preservation of resources and the extraction of relevant data from such resources into public and private land management and development process, and to identify as early as possible and resolve conflicts between the preservation of cultural resources and alternative land uses. This chapter is intended to carry out the goals and policies of the Rialto general plan.

  1. The moving will not have significant effect on the applicable goals and objectives of Rialto's general plan and on the implementation of this chapter.

  2. The structure in its original setting is not of such interest or quality that it would reasonably meet federal or state criteria of designation as a historic landmark and thus should be retained in that setting.

  1. The demolition will not have a significant effect on the applicable goals and objectives of Rialto's general plan and on the implementation of this chapter:

  3. The structure does not meet federal or state criteria for designation as a historic landmark.

  4. Conversion to a new use (adaptive re-use) permitted by right under current zoning, rehabilitation, or some other alternatives for preserving the structure is not economically feasible. A delay of up to one hundred eighty days may be permitted to determine the feasibility of alternatives. During this time the commission may consult with civic groups, public agencies and interested citizens.

D. A certificate of appropriateness for a new structure within a historic or urban conservation district shall take effect upon approval of the precise plan of design by the community development director or planning commission, as applicable. Existing structures identified as intrusions into historic or urban conservation districts do not need a certificate of appropriateness for demolition or moving.

E. A certificate of hardship permitting demolition, moving, a land division, new construction or alteration may be granted by the commission at the tune of consideration of the certificate of appropriateness only if the owner(s) of the designated property in question can produce evidence to show that:

  1. Reasonable use or return on the property is not possible under the conditions of the certificate of appropriateness; and

Alternative plans which would be in keeping with the interest of this chapter are not feasible.

The commission may delay the decision on granting the certificate of hardship for a period not to exceed ninety days to investigate plans to allow for a reasonable use of or return from the property or other measures to preserve the property, including selling the property to an individual or group that would preserve it. The commission shall review the evidence and make a written finding, stating the facts and reasons behind the decision. The applicant shall be notified by mail of the acceptance or denial of the certificate of hardship.
