Chapter 21.62 — FENCES AND WALLS

La Mirada Zoning Code · 2026-06 edition · ingested 2026-07-06 · La Mirada

21.62.010 Purpose .

This chapter sets forth standards for the construction and maintenance of fences and walls to ensure that such features can provide for privacy and safety without obstructing views, and without creating a public safety hazard or nuisance. (Ord. 612 Exhibit A (part), 2008).

21.62.015 Definitions.

Notwithstanding the provisions of Chapter 21.200 of this code, for purposes of this chapter, the following definitions shall apply:

(1) “Arterial wall” is any fence or wall, including retaining wall, which is immediately adjacent to or abuts a major/minor arterial roadway.

(2) “Electrified fence” means a fence or similar barrier that has electricity running through it to deter animals and people from crossing a boundary.

(3) “Fence” means a solid or open barrier, other than a wall, located above ground and intended to enclose or mark a boundary.

(4) “Major/minor arterial roadways” means a roadway designated a major or minor roadway on the city's General Plan.

(5) “Retaining wall” means a wall designed to resist lateral earth and/or fluid pressures, including any surcharge, in accordance with accepted engineering practice.

(6) “Slope” means an inclined ground surface, the inclination of which is expressed as a ratio of horizontal distance to vertical distance.

(7) “Structural compromise” is when a building or structure has been potentially compromised. The owner shall cause a structural inspection of the building or structure to be performed by a certified engineer when a structure is deemed to be compromised.

(8) “Structural failure” refers to loss of the load-carrying capacity of a component or member within a structure or of the structure itself. Structural failure is initiated when the material is stressed to its strength limit, thus causing fracture or excessive deformations. A licensed engineer shall review and determine when a retaining wall or wall show signs of structural failure.

(9) “Surcharge” is a vertical load imposed on the retained soil that may impose a lateral force in addition to the lateral earth pressure of the retained soil.

(10) “Wall” means a physical barrier constructed largely of masonry, brick, concrete, stucco, concrete block, or any combination thereof and intended to mark a boundary.

(Ord. 710, § 6, 2019; Ord. 650, § 6, 2012).

21.62.020 Permit requirements .

Unless otherwise exempt per Section 21.62.030, the construction, installation, or modification of any fence or wall shall require planning approval and a building permit to ensure compliance with applicable regulations of this chapter and title.

Notes:

  1. For commercial and industrial development, the designated approving authority may approve a fence or wall up to a maximum height of 10 feet in compliance with location and clear vision requirements of this title.

  2. A protective fence enclosing any public property or an open area for games or a swimming pool shall not be subject to the limitations if constructed of wire or steel mesh capable of transmitting at least 90 percent of the light shining onto it.

  • (b) Measurement of Fence or Wall Height.

(1) For the purposes of this chapter, fence and wall height shall be measured as the vertical distance from the ground elevation or finished grade of the property on which the fence or wall is erected to the highest point of the fence or wall. However, the height of retaining walls shall be measured from the bottom of the footing to the top of the retaining wall. To allow for variation in topography, the height of a fence or a wall may vary up to six inches.

(2) Where there is a difference in the ground elevation or finished grade between two adjoining parcels of less than two feet, the height of any fence or wall constructed along the common property line shall be determined by using the finished grade of the highest contiguous parcel. When there is a difference in the ground level between two adjacent parcels of two feet or more, the height of a fence or wall shall be determined by the community development director. The community development director shall consider the physical and visual fence height impact on abutting properties.

(c) Walls Required Between Different Zoning Districts and Uses.

(1) Along the common boundary between a residential zoning district or use and a commercial or industrial zoning district and/or use, a minimum six-foot-high decorative solid masonry wall shall be constructed to serve as a visual screen and buffer between uses.

(2) Along the common boundary between any single-family zoning district or use and multi-family residential zoning districts and/or uses, a minimum six-foot-high decorative solid masonry wall shall be constructed to serve as a visual screen and buffer between uses.
