Rancho Cucamonga — Land Use

Last reviewed: July 2, 2026

Overview

This page explains how the City of Rancho Cucamonga's Development Code (commonly called Title 17) controls what uses are allowed on property, how uses are classified (permitted, minor-use, conditional), and where special overlay or form-based rules change those allowances. Land use permissions are set primarily by the base-zone tables and the form-based zone tables; development must also meet dimensional standards and any overlay/special-area rules. See the city's general zoning & planning overview and the core Zoning menu for navigation to related topics. § 17.02.010; § 17.30.030.

The code establishes three main things you must check for any project:

• Is the proposed use listed in the applicable land‑use table and what permit type is required (P / M / C / N)? (§ 17.30.030; Table 17.30.030-1).
• Do the site/building plans meet the development standards for that zone (setbacks, height, FAR, lot area)? (§ 17.36.040 and related tables).
• Is the parcel inside an overlay, form‑based or special‑planning area that modifies uses or standards (e.g., Cucamonga Station Overlay)? (§ 17.30.020; § 17.130.040; § 17.136.010).

You will frequently need to coordinate with parking, design review, and building/permitting requirements; see the city's pages for Parking, Design Review, and the statewide California Building Standards Code.

District-by-district breakdown

Note: the Development Code replaces older R-1/R-2 labels with base-zone abbreviations (for example VL, L, LM, M, MH, H, NI, IE, OSC, HR, P, FC/UC, plus special SP or form-based areas). Each district’s allowed uses are summarized from the land-use tables; numerical dimensional rules are in the development standards tables. See Table 17.30.030-1 and the zone descriptions for definitions. (§ 17.30.030; § 17.32.020; Chapter 17.26).

VL — Very Low residential

• Purpose: Preserve very low-density residential / semi‑rural parcels. (§ 17.26 descriptions).
• Typical permitted uses: single‑family dwelling, limited agricultural uses, accessory structures. Permitted/conditional status tracked in Table 17.30.030-1. (§ 17.30.030; Table 17.30.030-1).
• Key dimensional standards: Minimum lot sizes and setbacks are set by the zone-specific development standards and may be superseded by hillside or equestrian overlays; verify Table 17.36 series for parcel-specific numbers. (§ 17.36.x).
• Where it applies: Outlying residential and rural‑character neighborhoods shown on the zoning map. (§ 17.28.010).

L — Low residential

• Purpose: Low‑density single‑family neighborhoods.
• Typical permitted uses: single‑family dwellings, limited home occupations, accessory dwelling units (ADUs may be allowed per state and local ADU rules — verify local ADU chapter). Table 17.30.030-1 lists permit types. (§ 17.30.030).
• Dimensional standards: See development standards tables for setbacks, lot area, maximum coverage; hillside overlays may add restrictions. (§ 17.36.040; § 17.30.020 E).
• Where it applies: Established suburban neighborhoods; some parcels overlap overlays like E (Equestrian) or H (Hillside). (§ 17.26; chapter 17.38).

LM — Low‑Medium residential

• Purpose: Transition between low and medium density; supports duplexes/compact multifamily.
• Typical permitted uses: two‑family (duplex), multifamily (where shown P in table), community services (per table). (§ 17.30.030; Table 17.30.030-1).
• Standards: Refer to the base zone development standards and applicable design standards (articles IV–VII). (§ 17.36.x; article VII).

M — Medium residential

• Purpose: Typical medium-density multifamily and mixed housing types.
• Typical permitted uses: multifamily dwellings, certain live/work types, daycare facilities subject to permit in some placetypes. (§ 17.30.030; § 17.38.060 Placetype tables).

MH — Medium‑High residential

• Purpose: Higher-density apartments and mixed‑use where compatible.
• Typical permitted uses: multifamily, limited ground‑floor commercial per form-based rules. (§ 17.136.020 and Table 17.136.020-1 for form‑based areas).

H — High residential

• Purpose: Highest residential densities outside special planning areas.
• Typical permitted uses: multifamily, higher‑intensity services and some public facilities; see Table 17.30.030-1. (§ 17.30.030).

NI — Neo‑Industrial

• Purpose: Modern manufacturing, flex‑industrial and research/employment‑support uses targeted to high‑quality industrial campuses. (§ 17.36.040).
• Typical permitted uses: manufacturing, warehouse (with limits), parking facility and certain transit/utility uses; some uses require CUP or minor use permit per Table 17.30.030-1. (§ 17.30.030; Table 17.36.040-1).
• Key dimensional standards: Minimum lot area 0.5 ac (NI); front/side/rear setbacks and max heights follow Table 17.36.040-1 (see notes for heights and FAR exemptions). § 17.36.040 and Table 17.36.040-1.

IE — Industrial Employment

• Purpose: Traditional large‑format industrial and logistics land uses. (§ 17.36.040).
• Typical permitted uses: wholesale, distribution, large manufacturing; some industrial and utility uses require CUP and there are distance limits for sensitive adjacencies (e.g., truck/TRU buffers). (§ 17.30.030; table notes).
• Key dimensional standards: Minimum lot area commonly 5 ac (with options for 2 ac per conditions); max heights and setback rules in Table 17.36.040-1. See limits on single-user building sizes and conditional approvals for buildings >75,000 sf. (§ 17.36.040; Table notes).

OSC — Open Space / Conservation

• Purpose: Protect sensitive environmental resources, preserve waterways and open space. Uses are very limited; refer to Table 17.30.030-1 and special natural resource rules. (§ 17.30.030).

HR — Hillside Residential

• Purpose: Protect hill and slope resources; permit limited housing with technical review. (§ 17.30.040; § 17.26 descriptions).
• Typical permitted uses: single‑family dwellings only (maximum 2 units per net buildable acre; hillside development review required). (§ 17.30.040).
• Special requirements: Hillside review requires geological/hydrological/seismic studies; net buildable area determined through that review. (§ 17.30.040).

P — Parks / Public Facilities

• Purpose: Public parks, schools, and low‑intensity public facilities. Table 17.30.030-1 controls permitted public vs private uses. (§ 17.30.030).

FC/UC — Flood Control / Utility Corridor

• Purpose: Utility corridors, flood control infrastructure; only uses compatible with corridor function. (§ 17.26).

SP — Specific Plan / Special Purpose Zones

• Purpose: Large master‑planned areas with their own adopted implementing documents; specific plan rules take precedence where they conflict with base zone (unless the specific plan is silent). (§ 17.30.020 F).

Important Overlay Districts (examples)

• SH — Senior Housing overlay: incentives and special rules for senior rental housing. (§ 17.26; overlay descriptions).
• E — Equestrian overlay: keeps equine uses in certain residential areas. (§ 17.26).
• H — Hillside overlay: slope‑based design and reduced densities. (§ 17.26; § 17.30.020 E).
• CS — Cucamonga Station Area Overlay: modifies FAR, minimum density, and mandates ground-floor nonresidential uses within 1/4 mile of Metrolink station; also adds by‑right transit/parking uses. (§ 17.130.040).

Form‑based zones and the Land Use Standards chapter apply different allowed‑use tables for walkable placetypes; consult Chapter 17.136 and Table 17.136.020-1 for permitted uses in those form‑based zones. (§ 17.136.010–020).

Checklist

• Confirm base zone on the official zoning map (Chapter 17.28) and read the zone description. (§ 17.28.010).
• Verify the proposed use in Table 17.30.030‑1 (Allowed Land Uses and Permit Requirements by Base Zone): note P / M / C / N status. (§ 17.30.030).
• If inside a form‑based or station overlay, check Table 17.136.020‑1 and § 17.130.040 for modified uses/ground‑floor rules. (§ 17.136.020; § 17.130.040).
• Confirm dimensional standards (setbacks, heights, FAR, lot area) in the applicable development standard tables (Chapter 17.36 or form‑based zone tables). (§ 17.36.040; Table 17.36.040‑1).
• Determine whether a Minor Use Permit, Conditional Use Permit (CUP) (§ 17.20.060), or design review is required and prepare findings. (§ 17.20.060; § 17.20.040). Noted in the use tables.
• Check overlay rules (Equestrian, Hillside, SH, Cucamonga Station) and any specific‑plan documents for site. (§ 17.30.020 E–F; § 17.38.x).
• Prepare parking calculations and access plans complying with the city's Parking rules and drive‑through rules if applicable (see § 17.91). (§ 17.91.040).
• Confirm building, fire, and other agency permits (including California Building Standards Code / Title 24) before occupancy. (§ 17.12.030). Link to California Building Standards Code.

Risks & Ambiguities

Plain‑English Summary

Rancho Cucamonga’s Development Code (Title 17) decides what you can build on a parcel by: (1) identifying the base zone (VL, L, LM, M, MH, H, NI, IE, OSC, HR, etc.), (2) looking up the use in the allowed‑use table (P/M/C/N), (3) meeting the zone’s dimensional and site standards, and (4) following overlay or form‑based rules that may change the outcome. Always confirm the zone and any overlay; many non‑listed or borderline uses require a Similar Use Determination or a conditional permit. (§ 17.30.030; § 17.36.040; § 17.130.040).
