Glendora — Parking

Last reviewed: July 2, 2026

Overview

This page summarizes how Glendora's zoning ordinance controls parking, off‑street loading, and parking design. The city’s baseline off‑street rules are in § 21.03.020 (general parking and design standards) and several specific plan chapters (for Route 66, CCAP, Diamond Ridge, Arboreta, etc.) which modify or add rules for those plan areas. See the Glendora zoning overview and the city’s zoning resources for context; specific implementation details are in the cited code sections below.

Important first links for related topics appear below as they are referenced: the code’s baseline parking rules are in the Glendora Zoning materials; dimensional and setback interactions are discussed in Glendora Development Standards; design review intersections are covered under Glendora Design Review; special districts and exceptions appear in Glendora Overlay Districts; ADU parking issues are discussed in the Glendora ADUs topic and (for technical accessibility) in the California Building Standards Code.

Key Citywide Rules (what applies everywhere)

• Required off‑street parking (new structures, new uses, or additions that trigger new spaces) is governed by § 21.03.020. The rule requires parking on the same parcel unless a reciprocal/shared arrangement is authorized, and it requires maintained, exclusive temporary parking (not for storage/sales) while the use exists. § 21.03.020 also authorizes the Director to require a parking & loading study prepared by a registered traffic engineer.
• Parking stall dimensions, aisle widths, compact‑stall limits, and surface parking design (screening, pedestrian connections, lighting) are set out in § 21.03.020(C) and accompanying tables. Typical numeric standards include: standard stall 9'×20', compact 8'×17', 90° aisle 26', and compact stalls limited to 25% of stalls in excess of ten (numbers appear across multiple plan sections that reiterate or adapt these standards). See § 21.03.020(C)(1–4).
• Accessible parking must comply with the State standards in Title 24 of the California Code of Regulations (California Building Standards Code). The local code references Title 24 for accessible stall counts and dimensions. § 21.03.020(C)(4).
• Off‑street loading minima and design (minimum dimensions, location to avoid backing into public street) are in § 21.03.020(J): loading dimensions are stated as a minimum in many parts of the code (e.g., 15'×50' or a different table showing 10'×60' depending on the specific plan) and must allow on‑site maneuvering.

District-by-district breakdown

Note: the Glendora Municipal Code includes citywide standards and multiple Specific Plan / CCAP / other district rules that modify parking. Below are the districts that explicitly alter or define parking in the code and the controlling citations.

All zones (baseline)

• Purpose / typical uses: Applies to any new structure, new use, or qualifying addition. Baseline rules apply unless a specific plan or district says otherwise. Key rules are parking location (same parcel unless reciprocal), required maintenance/use, and the Director’s authority to require a parking study. § 21.03.020.
• Key numeric standards: standard stall 9'×20', compact 8'×17', 90° aisle 26', compact limit 25% of stalls in excess of ten; accessible per Title 24. § 21.03.020(C).
• Where it applies: Citywide unless superseded by a specific plan or district map. § 21.03.020.

Route 66 Specific Plan subdistricts (selected): BG, GCG, TCMU, RSC, TCO, LHG, GLG, GRG, CRR

• Purpose / typical uses: These subdistrict codes define mixed‑use, gateway, residential or commercial subareas along Route 66 and carry tailored requirements for lot layout, parking location, and screening. The Specific Plan requires off‑street parking and loading consistent with § 21.03.020, but with explicit modifications and locational rules in § 21.10.370.
• Key dimensional / location standards:
  • Required parking for commercial/mixed uses may be located on the same parcel or on another parcel within 400 ft of the parcel served (Route 66 exception). § 21.10.370(B)(1).
  • Parking setbacks and whether parking is permitted in front/side/rear are addressed in Table 6‑4 (Route 66 Specific Plan) — consult § 21.10.370 for the map/table. § 21.10.370(B)(1).
  • Parking design rules (stall sizes, aisle widths, compact stall caps, lighting, screening, and reserved public‑safety spaces) are spelled out in the Specific Plan and cross‑reference § 21.03.020 for standards. § 21.10.370 and related tables.
• Where it applies: Properties inside the Route 66 Specific Plan boundary (see the Specific Plan map and § 21.10.370).

CCAP / Village & Parking District rules (Central City Area Plan)

• Purpose / typical uses: The CCAP includes a Village Parking District, Parking Exemption District, and Parking Reduction District that change how on‑site parking is calculated for commercial or multifamily development within the CCAP area. See § 21.03.020 (K) and CCAP subsections.
• Key rules:
  • Parking Exemption District: exempts all commercial development within the district from on‑site parking requirements because public parking exists. § 21.03.020(K)(3) (CCAP text).
  • Parking Reduction District: exempts the first 1,000 sq ft of new commercial/retail from on‑site parking requirements; development over that threshold must comply with § 21.03.020. § 21.03.020(K)(4).
  • Multifamily parking rules in the CCAP reference one space per bedroom or district‑specific variants; see § 21.03.020(D/E) and CCAP subsections. § 21.03.020.
• Where it applies: CCAP mapping and the CCAP text identify boundaries — consult the CCAP maps in § 21.03.020(K/J).

Diamond Ridge Specific Plan

• Purpose / typical uses: Commercial / retail/entertainment center with site‑specific parking schematics and stall sizes. Diamond Ridge restates parking stall standards (e.g., standard 9'×20', compact allowances), drive‑aisle widths, compact stall caps (20–25% noted in plan variants), and loading dimensions (commonly 10'×60' or 15'×50' in other plan excerpts). See Diamond Ridge tables and § 21.11 and supporting figures.
• Key rules: Parking must be installed per the plan's stage of development; parking structures allowed with design review and specific safety/visibility criteria. § 21.11 (Diamond Ridge) and development review rules.
• Where it applies: Diamond Ridge specific plan area; check § 21.11 for maps and phasing.

Arboreta Specific Plan

• Purpose / typical uses: Residential subdivision with detailed guest/resident parking rules and prohibitions (e.g., RV prohibitions, guest vehicle street rules). § 21.12.220–240.
• Key rules: Guest parking may remain on streets during evening hours; accessory vehicles often required in enclosed garages; RV parking prohibited unless approved under strict administrative permit standards. § 21.12.220 and RV administrative permit rules.
• Where it applies: The Arboreta Specific Plan area. § 21.12.220.

Practical guidance / interpretation notes

• The starting point for any project is § 21.03.020. If your parcel lies within a Specific Plan (Route 66, Diamond Ridge, Arboreta, CCAP), that specific plan will frequently override or modify the baseline standards — read the applicable plan chapter (for Route 66 see § 21.10.370).
• Compact stalls are allowed but capped (typically 25%) and must be labelled COMPACT. Check the applicable plan as some specific plans reiterate a 20–25% limit. § 21.03.020(C)(3) and Diamond Ridge/Route 66 text.
• Driveways, aisles, and back‑out distances are regulated; for multi‑unit/mixed‑use projects design review often addresses curb cuts, pedestrian connectivity, and where garage access is allowed (e.g., CCAP discourages Glendora Avenue curb cuts). See CCAP / design standards and Glendora Design Review. § 21.03.020 and CCAP text.
• When in doubt about whether a parcel falls into a Parking Exemption or Parking Reduction district, verify the city map layers and the CCAP/Specific Plan maps — the code defers to district maps for exemptions. § 21.03.020(K).

Checklist

• Confirm whether the parcel is inside a Specific Plan (Route 66 § 21.10, Diamond Ridge § 21.11, Arboreta § 21.12) or the CCAP area — those can change parking rules.
• Calculate required off‑street parking using § 21.03.020 default ratios and the use‑specific tables (restaurants, retail, schools, warehousing, etc.). § 21.03.020(G).
• Lay out stalls to meet stall dimensions, aisle widths, compact stall caps, accessible stalls per Title 24, and show pedestrian connections. § 21.03.020(C).
• Provide off‑street loading in the number and size required or be prepared to justify a different solution with a parking/loading study. § 21.03.020(J).
• If proposing shared or off‑site parking (e.g., within 400 ft in Route 66), prepare and be ready to record shared‑parking agreements as required by the specific plan. § 21.10.370(B).
• If in CCAP Parking Exemption/Reduction District, document how that district applies (maps and findings). § 21.03.020(K).
• If seeking a parking exception or alternative (compact ratios, shared parking, on‑street loading), prepare a parking & loading study by a registered traffic engineer as the Director may require. § 21.03.020(H).

Risks & Ambiguities

Plain‑English summary

Glendora requires off‑street parking and loading to be provided for new uses per the citywide parking rules in § 21.03.020, but several Specific Plans (Route 66, CCAP, Diamond Ridge, Arboreta) adjust where, how much, and what kind of parking is required — for example, Route 66 lets some commercial parking be off‑site within 400 ft, and CCAP contains districts that can exempt or reduce on‑site parking; design details (stall size, aisles, accessible stalls) are numeric and must meet the cited sections. Always check the Specific Plan or district map that covers your parcel and be ready to produce a parking/loading study if requested.
