Claremont Zoning, Planning & Building Codes

Last reviewed: July 1, 2026

Overview

Claremont’s zoning is codified as Title 16 — Zoning of the Claremont Municipal Code; the ordinance names the title and establishes its purpose in § 16.000.000 and sets out the list of district symbols and names in § 16.000.020. The code is organized by district chapters (single‑family, commercial, industrial, institutional, special districts) with cross‑referenced chapters for common standards (height/setback measurement, parking, design review and accessory unit rules). Readers should treat each district chapter as the primary place to find permitted uses and then consult the cross‑reference chapters that contain citywide technical standards and review procedures (for example, the chapters on parking, accessory units, and architectural review).

How Claremont's code is organized

• Title name and broad authority: Title 16 — Zoning is established by the City as the Zoning Ordinance in § 16.000.000.
• District‑by‑district structure: the ordinance creates district chapters for each zoning district and places district‑specific permitted uses and development rules inside those chapters (for example, the RS single‑family chapter and the RM medium‑density chapter), while cross‑cutting technical standards live in separate chapters referenced from each district (see table of districts in § 16.000.020).
• Cross‑reference (where to find the big topics):
  • Setback, height and measurement rules and exceptions are handled within district chapters and refer to measurement/exception rules in Chapter 16.130 (district chapters routinely cite that chapter for interpretation of height/setback).
  • Parking requirements and parking‑area development standards are collected in Chapter 16.136 and are repeatedly referenced from district tables and chapters.
  • Design / architectural review (the Architectural Commission and related design review procedures) are centralized in Chapter 16.300 and are cited as the review authority for village and historical areas and many exceptions.
  • Conditional uses and discretionary permits are processed under Chapter 16.303 (conditional use permit provisions are invoked across district chapters).
  • Accessory units are regulated by a dedicated chapter (Accesssory Second Units) — see Chapter 16.333 as the local rule referenced from several districts.
  • Specific Plans and the Specific Plan District are governed by Chapter 16.081 and its cross references (and the Code references Chapter 16.318 for adoption procedure).

(For quick navigation, consult the citywide Zoning index at the top of Title 16 and then open the specific district chapter relevant to your site.)

Zoning district families

Claremont groups districts into named families; the code lists them explicitly in § 16.000.020. The main district families (as they appear in the table) include:

• RS (Single‑Family Residential districts) — various lot size variants.
• HC (Historical Claremont District) — special standards preserving Village character.
• RM (Medium‑Density Residential) and AV (Arbol Verde single‑family neighborhoods) — multi/small‑lot residential rules.
• MU, CP, CN, CL, CH, CF (Mixed‑Use and Commercial families, including CV Claremont Village and the CVO Claremont Village Overlay).
• B/IP (Business/Industrial Park) and CR (Commercial Recreation).
• IE/IR (Institutional Educational / Institutional Residential) and P / P/RC (Public / Park‑Resource Conservation), WP (Wilderness Park) and H (Hillside).
• SP (Specific Plan District) — where a specific plan applies the specific plan controls development instead of the base district rules.

(First time you look up any parcel, open the applicable district chapter named above for permitted uses and then the cross‑reference chapters for technical standards.)

Citywide development standards

Claremont keeps most numeric standards inside each district chapter while pointing to common technical chapters for definitions and measurement rules.

• How standards are organized: district chapters list lot‑size, setbacks, maximum stories, heights, lot coverage and often a table of parking; districts routinely say “see Chapter 16.130 for measurement” and “see Chapter 16.136 for parking,” so interpretive rules are centralized. Example: the Historic Claremont district lists lot area, minimum front yard 20 ft, maximum height 25 ft, and maximum lot coverage 35% and then refers to Chapters 16.130–16.151 for exceptions and accessory structures.

• Typical numeric anchors you will see in district chapters:

  • Front and street‑side setbacks are frequently 25 ft as a base minimum in commercial/industrial contexts where abutting non‑residential streets (§ 16.069.050 B) and the CV/village rules add their own landscape/setback requirements.
  • Where a district abuts a residential district, the code regularly requires increased setbacks (examples: institutional districts require 25 ft plus one foot for each foot of building height over 30 ft when adjacent to residential uses; I‑district height/setback tables codify stepbacks tied to distance from the residential boundary). See § 16.069.050 and § 16.069.060 for the institutional example.
  • Lot‑coverage and FAR are set per district (e.g., institutional campuses cap FAR 1.0 and maximum lot coverage 60% for campus project sites — see § 16.069.070–090).
  • The Historic Claremont district carries its own numeric package: front yard 20 ft, interior side 5 ft, street side 15 ft, rear 5 ft, max stories 2, and max height 25 ft (accessory limits and lot coverage also specified). See § 16.004.060.

• Parking and loading: required parking numbers and reductions for shared parking are shown in district tables but the development and layout standards for parking lots (stall dimensions, landscaping, circulation) live in Chapter 16.136 which district chapters explicitly reference.

• Accessory buildings and ADUs: accessory structures are subject to accessory‑building chapters (e.g., Chapter 16.133) and districts point to Chapter 16.333 for accessory second units (ADUs/JADUs) rules and permitting references. Several district chapters explicitly allow accessory second units subject to Chapter 16.333 (for example § 16.013.010 for RM and § 16.019.010 for AV).

(For the citywide numeric detail for your parcel, read the applicable district chapter first, then the cross‑reference chapters for parking, measurement, accessory buildings, and definitions.)

Specific plans & overlays

• Specific Plans: Claremont uses a Specific Plan District (SP) framework; the district chapter explains that the uses, development standards and procedures for an SP are those in the adopted specific plan and references the statutory adoption procedure. See § 16.081.000–020 for intent and the list of specific plan areas.
• Listed Specific Plan areas: the code lists several Specific Plan Areas by number and identifies those that remain applicable (Meadowood, Claremont Hills, Williams Avenue, The Grove, etc.) in § 16.081.020 (each SP has its own legal description tied to a tract or map).
• Overlays: the code includes specialized overlays such as the Claremont Village Overlay (CVO) and more recently a Housing Opportunity Site Overlay (newly adopted Housing Opportunity overlay code replaces an older HDR overlay). The Housing Opportunity Site Overlay establishes four overlay types — MFR 30, MFR 60, MU 30, MU 60 — with explicit maximum residential densities and minimum densities and is codified in Chapter 16.014 (see § 16.014.000–020). This overlay is the City’s local implementation step created to meet Housing Element commitments.

(If your site lies within an overlay or SP, the overlay/SP controls may supersede the underlying district standards — the overlay/SP chapters say so directly.)

Building permits & review

• Permit pathways: day‑to‑day construction and building permits still require plan check against the California Building Standards and the local zoning rules. Where projects require discretionary approvals, the code routes them to the Architectural Commission, Planning Commission, or City Council per the procedure chapters (design review in Chapter 16.300, conditional use permits in Chapter 16.303, specific plan/master plan approvals in the master‑plan procedures referenced in district chapters). See the references to Ch. 16.300, Ch. 16.303, and the master plan approval criteria embedded in institutional/master‑plan language.
• Design review & Village character: projects in the Claremont Village and in historical areas are explicitly subject to the Village Design Plan and Architectural Commission review; see the Village Design Plan references and the requirement that village projects conform to the Village Design Plan in § 16.051.040, § 16.060.020–030 and related sections.
• Discretionary vs ministerial: many routine residential projects on single lots (including most ADU permits when eligible) follow ministerial processes referenced in the accessory second unit chapter (Chapter 16.333). Projects that change use, increase intensity, or require exceptions (setback reductions, height increases, CUPs) require discretionary review under Chapter 16.303 and design review under Chapter 16.300 as district chapters require.
• Master plans and institutional projects: large campuses and institutional master plans follow additional master plan procedures and findings (the institutional chapters require master‑plan consistency with the General Plan and sustainability/site‑interface findings; see the institutional master‑plan rubric in the institutional chapter). Individual projects consistent with an approved master plan may avoid separate environmental review unless new substantial information arises.

Practical orientation: first confirm the parcel zoning on the Official Zoning Map, read the district chapter for permitted uses and numeric standards, then check the cross‑reference chapters (16.130, 16.136, 16.300, 16.333) for measurement, parking, design review and accessory unit rules before preparing a permit filing.

State housing law in Claremont

Claremont’s code cross‑references local accessory unit rules and (most recently) adopted a Housing Opportunity Site Overlay to implement Housing Element goals; the interaction with state law is as follows:

• Accessory dwelling units (ADUs / JADUs): district chapters repeatedly permit accessory second units subject to the local accessory unit chapter 16.333 (see § 16.013.010 for RM and § 16.019.010 for AV). Local ADU procedures in Chapter 16.333 must be applied consistent with state ADU law; state ADU requirements (ministerial permits, maximum sizes, setbacks, parking exemptions in many cases) are summarized in the state ADU guidance and statute summaries. For how state ADU rules limit local restrictions, see the city’s cross‑references to accessory unit permitting and the statewide ADU summaries (local code cites accessory second units throughout).
• Housing Opportunity Overlay & density: the local Housing Opportunity Site Overlay establishes MFR 30 / MFR 60 / MU 30 / MU 60 overlays and sets local maximum and minimum densities for those overlay areas (see § 16.014.020). That overlay is Claremont’s local tool to implement its Sixth Cycle Housing Element and to accommodate higher densities where the City has designated opportunity sites.
• SB 9 / ministerial duplex and lot‑split authority: no explicit text mentioning "SB 9" or a local ministerial SB 9 implementation was found in the retrieved materials. If you’re proposing a two‑unit or lot split under SB 9, verify with the Planning Division whether the City has adopted a ministerial process or local objective standards to implement SB 9 on Claremont parcels. Not found in retrieved materials — verify with the jurisdiction.
• Density bonus, affordable housing incentives and tenant rent controls: the retrieved local code files show the City’s overlay strategy and Housing Element implementation steps (Housing Opportunity overlay) but do not include an explicit density‑bonus chapter text excerpt in the retrieved snippets; likewise, the code snippets provided do not show a local rent‑control ordinance (rent control is typically elsewhere in municipal code if adopted). For density bonus and rent regulation status, confirm current municipal code chapters or ordinances with the Planning Department. Not found in retrieved materials — verify with the jurisdiction.

State references: for mandatory state ADU standards and recent changes to ADU ministerial rules consult the California ADU guidance (summary excerpt in uploaded 2025 ADU handbook). The handbook summarizes state limits on local ADU restrictions (size, setbacks, parking and related ministerial requirements) and is a helpful companion to local Chapter 16.333.

Information gaps / what to confirm with the Planning Division

• No explicit SB 9 implementation language was located in the provided excerpts; check whether the City has adopted an objective ministerial standard set for SB 9 lot splits and duplex ministerial approvals. Not found in retrieved materials.
• The retrieved materials do not include a complete copy of Chapter 16.333 (Accessory Second Units) text in the snippets I reviewed, so verify the local ADU numeric limits, required findings, and ministerial timelines in that chapter before filing. Not found in retrieved materials (refer to Chapter 16.333 directly).
• I did not find an explicit local density‑bonus implementation section in the excerpts. Confirm whether the City has enacted local procedures implementing the state density bonus statute. Not found in retrieved materials.
