Long Beach R-1-S: Single-Family Residential, Small Lot District Guide

Jurisdiction: Long BeachCode Version: April 2026

The R-1-S District in Long Beach is a single-family residential zone specifically designed for small lot configurations, requiring a minimum lot area of only 2,400 square feet and a minimum width of 30 feet. Located primarily within high-amenity areas like the Coastal Zone, the Long Beach R-1-S District limits density to one detached dwelling unit per lot while allowing for a relatively high Floor Area Ratio of 1.2.

Purpose and General Character

The primary intent of the R-1-S District is to recognize and accommodate existing subdivision patterns in Long Beach where smaller lots are prevalent. By providing a framework for modern home construction on these reduced footprints, the R-1-S District ensures that residential development remains compatible with the surrounding neighborhood character, particularly in areas with significant open space amenities [Section 21.31.020]. The Long Beach R-1-S District implements Land Use District No. 1 of the City’s General Plan [Section 21.31.020.A].

Permitted Land Uses

The R-1-S District is strictly limited to low-density residential uses and compatible supporting activities. The following table summarizes the primary permissions for land use in the Long Beach R-1-S District:

R-1-S Development Standards

To maintain the residential scale of the R-1-S District, Long Beach enforces specific requirements regarding building size, height, and placement.

Standard Requirement
Minimum Lot Area 2,400 sq. ft.
Minimum Lot Width 30 ft.
Maximum Building Height 24 ft. (midpoint) / 28 ft. (peak)
Floor Area Ratio (FAR) 1.2
Maximum Units Per Lot 1
Front Yard Setback 8 ft. (averaging may apply)
Side Yard Setback 3 ft.
Rear Yard Setback 8 ft.
Minimum Usable Open Space 6% of lot area

[Table 31-2A]

Setback and Height Nuances

In the Long Beach R-1-S District, front yard setbacks may be adjusted based on "front yard averaging" if one or both adjoining lots already encroach into the required 8-foot setback [Section 21.31.215.C.3]. Building height is generally measured to the midpoint of the roof, though the R-1-S District allows for a peak height of 28 feet to accommodate roof pitches [Table 31-2A].

Parking Requirements

Parking requirements in the R-1-S District are determined by the number of bedrooms and the location of the property. Because the R-1-S District is often situated within the Long Beach Coastal Zone, specific coastal standards typically apply.

Unit Type Standard Parking (Per Unit) Coastal Zone Only (Per Unit)
0 Bedrooms (under 450 sq. ft.) 1.0 space 1.0 space
1 or more Bedrooms 1.5 spaces 2.0 spaces
2 or more Bedrooms 2.0 spaces 2.0 spaces
Guest Parking 1 space / 4 units* 1 space / 4 units*

*Guest parking is only required when four or more detached units are proposed as one development on the site. [Table 41-1A]

In all cases, required parking spaces in the R-1-S District must be provided within a fully enclosed garage [Section 21.41.213].

Accessory Dwelling Units (ADUs)

Long Beach allows for the creation of Accessory Dwelling Units on R-1-S District lots that contain an existing single-family home. These units can be "Limited" (created from existing space) or "Conforming" (new construction) [Section 21.51.276].

  • Maximum Unit Size: For Conforming ADUs, the size is limited to 50% of the primary dwelling's GFA or 800 sq. ft., whichever is less [Table 51.276-1].
  • Setbacks: Conforming ADUs must follow the same front and side setbacks as the primary R-1-S structure, though the rear setback is reduced to 5 feet for detached units [Table 51.276-1].

Fencing and Walls

Fences and garden walls in the R-1-S District are subject to height limitations to ensure visibility and neighborhood aesthetics [Section 21.43.010].

  • Front Yard: Maximum 3 feet in height [Table 43-1].
  • Side/Rear Yard: Maximum 6 feet 6 inches in height [Table 43-1].
  • Corner Cutoffs: Fences within the triangular corner cutoff area at intersections must not exceed 3 feet in height to maintain traffic visibility [Table 43-1].
