Last reviewed: July 6, 2026

Overview

Los Angeles’ original Planning and Zoning Code is Chapter 1 of the Los Angeles Municipal Code. It establishes the City’s official zone designations (e.g., R1, R3, C1, C1.5, C4, C2, CM, M1–M3, PF), the “height district” system, and core development rules (uses, yards, density, height, and parking) that still apply citywide unless superseded. The newer Los Angeles Zoning Code (Chapter 1A) is being mapped incrementally; until then, Chapter 1 governs most properties. The City’s zones and height districts are mapped per § 12.04, with height and FAR limits primarily set by § 12.21.1.

In Los Angeles, every parcel carries both a base zone (e.g., R1, C2) and a separate height district suffix (e.g., “-1,” “-1XL,” “-1VL,” “-1SS”). Both designations control what you can build. See § 12.04.C and § 12.21.1.

Use this page alongside the City overview pages for Los Angeles Zoning, Los Angeles Land Use, Los Angeles Development Standards, and Los Angeles Parking. For design approvals, also see Los Angeles Design Review and Los Angeles Overlay Districts. Building work must comply with the California Building Standards Code.

How Chapter 1 is organized (what it establishes)

  • Zones, symbols, and map: the City is divided into zones, with an order of restrictiveness; each lot shows a zone and a height district (e.g., “C2-2”) on the Zoning Map; see § 12.04.
  • Height/FAR system: citywide height and FAR limits, including “L,” “VL,” “XL,” and “SS” sub-districts, are set in § 12.21.1; Century City has separate height rules in § 12.21.2.
  • Zone-specific regulations: residential zones (R1 § 12.08; R2 § 12.09; RD § 12.09.1; R3 § 12.10; R4 § 12.11; R5 § 12.12) and commercial zones (CR § 12.13; C1 § 12.13; C1.5 § 12.13.5; C4 § 12.16) define permitted uses and site standards.
  • General rules/parking/exceptions: § 12.21 includes general standards (e.g., yards, parking), with § 12.21 A.4 governing minimum parking (plus exceptions and reductions), and § 12.22 and § 12.24 providing exceptions and conditional uses.

Height Districts and Citywide Height/FAR controls

  • Base FAR in Height District No. 1 is generally:
    • For lots in commercial or industrial zones: 1.5× the buildable area. For all other zones (except RA, RE, RS, R1), 3.0× in HD No. 1. See § 12.21.1 A.1.
  • Sub-districts in HD No. 1:
    • “L” Limited: max 6 stories/75 ft; “VL” Very Limited: max 3 stories/45 ft; “XL” Extra Limited: max 2 stories/30 ft; “SS” Single-Story: 1 story/overall 18 ft cap. See § 12.21.1 A.1.
  • Single-family envelope and heights:
    • Outside hillsides/coastal: max 33 ft in R1/RS/RE9 (or 28 ft with low-slope roof); R2 max 33 ft. See § 12.21.1 A.
    • Hillsides: Chapter 1 sets a detailed “envelope height” and setback regime for R1/RS/RE/RA in hillsides (Table 12.21 C.10-1 and C.10-4). See § 12.21 C.10.
  • Special areas: properties in Century City and certain plan areas follow § 12.21.2 (Century City), § 12.21.3 (Redevelopment), § 12.21.4 (Enterprise Zones), or § 12.21.5 (Centers Study Areas), as referenced in § 12.21.1.

Parking and related rules anchored in Chapter 1

  • Minimum off-street parking is set by § 12.21 A.4, with a set of exceptions and geographically targeted reductions (e.g., Chinatown, Hollywood, Wilshire Center/Koreatown). Redevelopment and Enterprise Zones may qualify for reduced ratios; see § 12.21 A.4.
  • Downtown Community Plan Area entitlements deemed complete before Chapter 1A’s operative date are exempt from minimum parking in § 12.21 A.4; see “Downtown Community Plan Area Projects” in § 12.21 A.4 (z).
  • The PB Parking Building Zone has height-specific limits (e.g., 2 stories in HD No. 1; 6/10/13 stories in HD Nos. 2/3/4), addressed within § 12.21.1.
  • The City Planning Commission may authorize reduced on-site parking and remote off-site parking in connection with certain Commission actions; see § 12.21 A.4 (y).

Note: Detailed use lists for C2 were not captured in the retrieved materials; C4 allows any C2-permitted use with exceptions per § 12.16 A.2. Verify C2 specifics with the jurisdiction.

Practical notes

  • Many “by-right” housing/mixed-use projects must also satisfy open space, yards, and minimum density rules added to several commercial and multi-family zones in 2025; for example, CR/C1/C1.5 include a minimum density standard of one unit/guest room per 2,000 sf of lot area for qualifying housing projects; see each zone’s area subsection (e.g., § 12.13 C; § 12.13.5).
  • For special downtown provisions, see the Greater Downtown Housing Incentive references in § 12.11 C.3 (applies to R4/RAS4/R5/CR/C2/C4/C5).
  • Parking ratio exceptions for historic buildings, redevelopment areas, and remote/off-site parking are in § 12.21 A.4; downtown C1A transition: see Chapter 1A link but apply Chapter 1 unless remapped.

Checklist

  • Identify your base zone and height district on the City Zoning Map (e.g., “R3-1VL”). See § 12.04.
  • Confirm if your parcel is in a specific plan, HPOZ, or other overlay; Chapter 1 may defer certain limits (see § 12.21.1 references).
  • Determine allowed uses and required yards/lot area from your zone’s section (e.g., R1 § 12.08; C1 § 12.13).
  • Apply height/FAR caps from your height district and any “L/VL/XL/SS” limits (see § 12.21.1).
  • Check parking requirements and any applicable exceptions/reductions (see § 12.21 A.4).
  • If seeking relief, confirm whether a Los Angeles Variances and Exceptions pathway or conditional use in § 12.24 is available.
  • Coordinate your permit path with Los Angeles Permits & Forms and verify any Los Angeles Nonconforming Uses or Los Angeles Signage limits relevant to your scope.

Risks & Ambiguities

Issue Why it matters What to verify
Height district suffixes (1, 1L, 1VL, 1XL, 1SS) They can reduce stories/feet beyond base zoning Confirm your mapped suffix and apply § 12.21.1 A.1 limits; many blocks have “-1XL” or “-1VL.”
Hillside controls for single-family Height/yard “envelope” can materially change design If in hillsides, apply § 12.21 C.10 tables and measurement rules before designing massing.
Downtown/district incentives Yard and unit-count rules may be waived or altered If in Greater Downtown Housing Incentive Area, see § 12.11 C.3; parking exemptions in § 12.21 A.4 (z).
CR/C1/C1.5 minimum density New 2025 standards can require a floor of units Check your zone’s area subsection (e.g., § 12.13 C; § 12.13.5) for “minimum density” applicability.
PB parking-building limits Height caps for stand-alone parking PB building heights are capped in § 12.21.1; C1.5 references PB rules for parking structures.
C2 base permissions C4 relies on C2 list; incomplete capture here If designing to C2 allowances, confirm the C2 use list in Chapter 1; C4 incorporates C2 with exceptions in § 12.16 A.2.

Plain-English Summary

Chapter 1 is Los Angeles’ legacy zoning code. It tells you what your base zone allows, what your height district caps, how far your building must sit from property lines, and how much parking you need. Before drawing plans, look up your zone and height district, check hillside/downtown rules if relevant, and confirm parking and any incentives or exceptions that apply.

Frequently asked questions

What can I build on an R-1 lot in Los Angeles?

Generally a one-family dwelling with accessory structures, subject to R1 floor area limits, R1 yards, and height caps; limited two-family is allowed only near C/M boundaries within 65 feet. Heights are typically 33 ft (28 ft with low-slope roof) outside hillsides/coastal. See § 12.08 A and § 12.21.1. Verify hillside rules in § 12.21 C.10.

What are Los Angeles height districts (1, 1L, 1VL, 1XL, 1SS)?

They are suffixes that cap floor area and/or stories/feet on top of your base zone. Examples: 1-L = 6 stories/75 ft; 1-VL = 3 stories/45 ft; 1-XL = 2 stories/30 ft; 1-SS = single-story with 18 ft cap. See § 12.21.1 A.1.

What is the minimum lot area per dwelling unit in R2 and R3?

In R2, it is 2,500 sq ft per dwelling unit (with legacy-lot exceptions). See § 12.09 C.4. The R3 value is specified in § 12.10 C.4, which was not captured in the retrieved materials—verify with the jurisdiction.

Do I need yards in CR or C1 zones if I build residential units?

Yes. In CR, side yards are required on corners, when abutting A/R zones, and for residential portions; a 15 ft rear yard is required. C1 residential yards/area standards are set in § 12.13 C (not fully captured here). See § 12.13 C.

How does parking work under Chapter 1?

Parking minimums are set in § 12.21 A.4, with exceptions for historic buildings, redevelopment areas, and CPC-authorized reductions/remote parking. Some Downtown projects with older entitlements are exempt from minimums per § 12.21 A.4 (z).

Are there special single-family rules in the hillsides?

Yes. Hillside R1/RS/RE/RA lots must meet special setbacks, grading limits, and an “envelope height” measured from hillside grade. See § 12.21 C.10 (including Tables 12.21 C.10-1 and C.10-4).

Does Chapter 1 still apply if I see “Title 17 Zoning” elsewhere?

Los Angeles City’s zoning is Chapter 1 of the LAMC (not “Title 17”). Chapter 1 remains in effect citywide unless your Community Plan area has been remapped into Chapter 1A. See § 12.04 and the Los Angeles zoning & planning overview.

Can commercial zones include housing by right?

Yes, several commercial zones allow residential or mixed-use, often by cross-reference to R3/R4 standards, and some now include “minimum density” floors for qualifying housing projects. See CR/C1/C1.5 area provisions (e.g., § 12.13 C; § 12.13.5).

Where do I find design review or overlay requirements?

Overlays and plan areas can override baseline Chapter 1 rules (e.g., height, yards). Start with Los Angeles Overlay Districts and Los Angeles Design Review, then return to § 12.21.1 for how specific plans defer height/FAR.

Do ADUs change what I can build in R zones?

Chapter 1 interacts with state ADU law; see Los Angeles ADUs and California ADU law. Apply R1/R2 standards for primary dwellings while ensuring ADU allowances are met. Verify site standards in § 12.08 and hillside rules in § 12.21 C.10.
