Title 17 — Zoning

Chapter 17.05 — RESIDENTIAL ZONES—STANDARDS AND USES

South El Monte Zoning Code · 2026-06 edition · ingested 2026-07-07 · South El Monte

§ 17.05.010. Intent and purpose.

  • A. Single-Family Residential Zone (R-1). The single-family residential zone (R-1) is designed to provide for conservation and development of stable, attractive single-family residential neighborhoods, protected from encroachment by uses which may be detrimental to the enjoyment of property rights.

  • B. Multiple-Residential Zone (R-2). The multiple-residential zone (R-2) is designed to permit multiple development on existing smaller lots which are not suitable for more intensive multiple residential development. These regulations will permit better utilization of properties while retaining the low-density single-family appearance of the areas.

  • C. Multiple-Residential Zone (R-3). The multiple-residential zone (R-3) is designed to provide areas throughout the city in which a range of multiple residential development can be located and protected from encroachment by incompatible uses.

  • (Ord. 1271, 4/23/2024)

§ 17.05.020. Uses.
