Title 18 — Zoning

Chapter 18.41 — ARCHITECTURAL REVIEW

Norco Zoning Code · 2026-06 edition · updated 2026-07-06 · Norco

§ 18.41.02. Intent and Purpose.

It is hereby found and declared that the City of Norco lies in a natural setting of rural, scenic and historical beauty; that this rural environment generates a strong characteristic for development of Norco as a new equestrian focal point in Southern California; that this unique rural environment and historically significant location contributes a material economic advantage to the citizens, business, and industry within the City and particularly to the property owners who reside therein; that the City of Norco is in the midst of a significant, if not its greatest, rate of growth and development and that the development of the community in an orderly manner with compatible uses and appearances of structures within and between zones and with the natural rural environment is necessary to maintain such historic and economic advantage, to stabilize, protect, and maintain property values, to encourage permanence of desirable residential areas, to promote trade and commerce, and to assure a continued sound economic growth of the City and well being of its economy and its people. (Ord. 801, 2003)

§ 18.41.04. Applicability.

While encouraging the broadest possible range of individual and creative design and without depriving a property owner of an efficient and full use thereof which is otherwise lawfully allowed, the use and development of property in those zones wherein this chapter is referred to, and all Conditional Use Permit and Variance Applications shall be governed by this chapter. Architectural Review is found to be necessary to assure that the nature and appearance of any use and development will be compatible and harmonious with the use and enjoyment of surrounding properties and will not have a material or substantially deleterious effect upon the historic, economic, social, and cultural well-being and development of the community or the peace, health, safety, and general economic welfare of its inhabitants.

(Ord. 801, 2003)

§ 18.41.06. Content of Required Plans.

The Plans to be submitted for review under this chapter shall contain all the elements and data required in Chapter 18.40 (SITE PLAN REVIEW). In addition, the plans shall include all exterior elevations and architectural features; the nature, texture and color of all materials to be used; and such other information as may be required by the Planning Director to enable the Planning Commission to make a proper review and take action thereon. (Ord. 801, 2003)

§ 18.41.08. Procedure for Architectural Review.

Plans submitted for review under the terms of this chapter shall be submitted and reviewed concurrently with and subject to all the terms and conditions of plans submitted for Site Plan Review. All of the regulations of Section 18.40 (SITE PLAN REVIEW) shall apply. (Ord. 801, 2003)

§ 18.41.10. Criteria for Architectural Review and Approval.

In addition to those criteria listed in this chapter, the Planning Commission (and City Council on appeal) shall consider and weigh: The nature of specific uses, in particular zones and geographic areas, and the requirements of utility with respect to the structures proposed for uses; site dimensions with relation to the structures proposed and the required utility thereof; the adequacy and conformity and harmony of external design, colors, materials, and architectural features with neighboring structures and use of the improvements proposed on the parcel with improvements existing or permitted on neighboring sites, and compatibility with established design parameters such as those outlined in specific plans.
