Overview

This page summarizes the City of Compton's off‑street parking, loading and bicycle parking rules as written in the local zoning ordinance (Title 30 / Zoning Chapter: § 30-21 and related sections). The code sets use‑based minimums (Table 30-21.A) and detailed design, landscaping, ADA, loading and location rules that apply citywide; special procedures exist for Modified Parking Requirements (MPR) and Planned Developments. See the zoning map and district rules for where each zone applies. § 30-21 and the tables are the controlling text for parking, loading and bicycle requirements.

This page links to related local topics you’ll likely use while preparing plans: the City’s Compton Zoning, Compton Development Standards, Compton Design Review, Compton Overlay Districts, Compton ADUs and the California Building Standards Code.

Key takeaways (short)

  • Required parking counts are use‑based (Table 30-21.A, § 30-21.3) — the zone (R-L, C-L, etc.) does not change the base count except where a Planned Development or MPR specifically overrides.
  • Design and dimension standards (stall size, aisle widths, vertical clearances, surfacing, landscaping, lighting, wheel stops) are mandatory for all required parking (§ 30-21.3, § 30-21.5, § 30-21.6, § 30-21.7).
  • Bicycle parking is required for most non‑residential uses at 1 bicycle space per 20 vehicle spaces required (§ 30-21.3.g).
  • Loading is required for nonresidential buildings > 7,000 sq ft and follows Table 30-21.D (1 space for 7,001–20,000; 2 for 20,001–50,000; 3 for 50,001+), minimum loading stall 12' x 25' (§ 30-21.10).

District-by-district (how parking rules apply across Compton zones)

Note: the City’s zones are the ones listed in § 30-4; parking minimums themselves are use-based under § 30-21, not set by zone. Where a zone’s text establishes special parking rules, that is noted and cited.

R-A (Residential Agriculture)

  • Purpose & typical uses: large single‑family lots; rural/residential uses. (§ 30-7.1).
  • Parking implication: Required residential parking is set by use (single‑family detached = 2 enclosed spaces/dwelling in Table 30-21.A) and must be located on the same lot (§ 30-21.3.c, § 30-21.3.h). Driveways and backup dimensions are regulated (§ 30-21.9.f).

R-L (Low‑Density Residential)

  • Purpose & typical uses: single‑family homes (formerly R-1). (§ 30-8.1)
  • Key dimensional / parking notes: lot, setback and front‑yard rules in § 30-8 apply to siting of parking/driveways; parking counts remain use‑based (Table 30-21.A: 2 enclosed spaces/dwelling for single‑family). Residential parking design rules (garage size, backup, paving) apply (§ 30-21.9).

R-M (Medium‑Density Residential)

  • Purpose & uses: multi‑family and denser single‑family patterns (former R-2). (§ 30-9.1).
  • Parking implication: Table 30-21.A sets multifamily ratios (e.g., 1.5–2 spaces/unit depending on bedrooms plus guest ratios); design, ADA and bicycle parking rules apply. Planned or site-specific projects may set different arrangements as a condition of approval. § 30-21.3, § 30-21.9.

R-H (High‑Density Residential)

  • Purpose & uses: highest residential densities (formerly R-3). (§ 30-4, § 30-5).
  • Parking implication: multifamily standards in Table 30-21.A control; additional site amenities/assignments for planned condominium projects are spelled out in Planned Development rules when applicable (§ 30-17/18 references).

C-O (Professional Office), C-L (Limited Commercial) and C-M (Commercial Manufacturing)

  • Purpose & typical uses: office/retail/auto parking/industrial uses per each zone’s use list (see § 30-12 for C-L uses).
  • Parking implication: nonresidential parking minimums are in Table 30-21.A (e.g., 1 space/250 sf for general retail/office; restaurants, hotels, auto uses have specific ratios) and nonresidential surfacing, striping, carpool set‑aside (10%) and paving standards apply (§ 30-21.3.c, § 30-21.6, § 30-21.5.g). Loading thresholds and dimensions are in § 30-21.10 and Table 30-21.D.

M-L (Limited Manufacturing) and M-H (Heavy Manufacturing)

  • Purpose & uses: industrial and warehousing uses; parking demands vary. (§ 30-4).
  • Parking implication: industrial parking standards and special rules (e.g., transportation yards, equipment) are in Table 30-21.A and the MPR rules (for large warehouses >10 acres) may apply; MPR requires a parking demand study and Planning Commission approval (§ 30-21.12).

B (Buffer), P (Automobile Parking), D (Planned Development), B‑O (Billboard Overlay)

  • B and P are special-purpose zones listed in § 30-4; P is intended for parking uses (automobile parking). Planned developments (D) use base‑zone standards unless the Commission sets specific parking conditions; condominium projects must provide 2 enclosed spaces/unit and 1 visitor space / 4 units where specified (§ 30-18). Overlay rules can modify parking locally.

Practical rule: the parking minimum is set by the use (Table 30-21.A, § 30-21.3). Zones set land use permissions and dimensional standards that influence feasible parking layouts (setbacks, lot coverage, driveway widths).

Plain‑English guidance and interpretation (practical)

  • Start by identifying the primary use and apply Table 30-21.A to compute the minimum number of spaces; fractions round up (§ 30-21.3.c).
  • Dimension the stalls, aisle widths and vertical clearances to the code tables (stall = 9' x 20' standard; aisle widths per Table 30-21.B; vertical clearances per Table 30-21.C) and provide the required landscaping and lighting plans (§ 30-21.3.b, § 30-21.5, § 30-21.6).
  • If proposing industrial/warehouse on a large parcel (≥ 10 acres), consider an MPR and prepare a parking demand study using ITE or survey data (§ 30-21.12).
  • If you want offsite parking, site it within 300 feet and record the covenant; get Planning Director approval (§ 30-21.3.h.2).

Checklist

  • Identify the principal land use and compute required spaces using Table 30-21.A; round fractions up (§ 30-21.3.c).
  • Show stall layouts with dimensions (standard 9' x 20'; compact 8' x 16'), aisle widths per Table 30-21.B, vertical clearances per Table 30-21.C (§ 30-21.3.b, Table 30-21.B, Table 30-21.C).
  • Include ADA/handicap spaces per State/ADA rules and ensure they count toward minimums (§ 30-21.4).
  • Provide landscape plan for parking per § 30-21.6 (10 ft planting strip from ROW, tree counts, irrigation).
  • For nonresidential: mark 10% carpool area, motorcycle stall if ≥25 spaces, and provide bicycle parking at 1 per 20 vehicle spaces (§ 30-21.3.f–g, § 30-21.5.g).
  • For >7,000 sq ft nonresidential, provide on‑site loading per Table 30-21.D and 12' x 25' minimum stalls (§ 30-21.10).
  • If proposing off‑site parking, prepare legal covenant and obtain Planning Director approval (distance ≤ 300 ft) (§ 30-21.3.h.2).
  • If requesting reduced parking (MPR), prepare a parking demand study using ITE or comparable surveys and route to Planning Commission / City Council (§ 30-21.12).

Risks & Ambiguities

Issue Why it matters What to verify
Use not listed in Table 30‑21.A The code says unlisted uses follow similar traffic‑generating uses and Planning Director determines the standard (§ 30-21.3.c) — subjective determination risk. Verify Planning Director interpretation for your specific use and obtain written determination; prepare a trip/parking study if needed.
Off‑site parking covenant Off‑site parking is allowed but must be within 300 ft and recorded; enforcement/long‑term maintenance depends on covenant language (§ 30-21.3.h.2). Confirm recorded covenant terms with City and County Recorder and get Planning Director pre‑approval.
ADU parking exceptions vs. local ADU rules City ADU text lists one space per ADU plus exemptions (transit proximity, historic district, within same structure, car share, on‑street permit restrictions). State ADU law also restricts local parking requirements. For ADUs, check the local ADU subsection and apply exemptions; verify ministerial ADU rules with Planning staff. (§ local ADU rules in ordinance)
Large industrial MPR limits MPRs apply only to eligible industrial/warehouse projects on lots ≥10 acres and cannot be used for residential/commercial (explicit) (§ 30-21.12.f.4). If your site is large industrial, confirm applicability; MPR requires study and Commission/Council approval.
Bicycle parking exemptions The code allows exemptions if Planning Director finds location or use not bicycle‑friendly (§ 30-21.3.g.3). Obtain written approval and rationale from the Planning Director; include in project submittal.

Plain‑English Summary

Compton’s zoning code requires off‑street parking based on the type of use (consult Table 30‑21.A), with detailed rules about stall size, aisles, surfacing, landscaping, ADA spaces, bicycle parking and loading docks; some large industrial sites can seek a Modified Parking Requirement, and ADUs have a special one‑space rule with stated exemptions. Always confirm the Planning Director/Architectural Review Board interpretations for uses not listed or when proposing off‑site or reduced parking.

Frequently asked questions

What counts as the required number of parking spaces for my business in Compton?

Compute parking from the use‑based Table 30‑21.A in the zoning ordinance (the "Parking Space Requirements" table) and round fractions up; if your use isn’t listed the Planning Director assigns a comparable use standard (§ 30-21.3.c).

Do single‑family homes in Compton need off‑street parking? If so, how much?

Yes — single‑family detached dwellings require 2 enclosed spaces per dwelling (Table 30‑21.A); residential parking must be on the same lot and meet the garage/driveway dimensions (see § 30‑21.3.c and § 30‑21.9).

If I build an ADU, do I need to add a parking space?

Compton’s ADU rules require 1 off‑street space per ADU, but list exemptions (within 1/2 mile of transit, inside historic districts, part of the primary dwelling/accessory structure, where on‑street permits are restricted, or near a car‑share spot). Verify with the ADU subsection and Planning staff when filing.

How much bicycle parking does my retail or office project need?

Bicycle parking is required at a rate of 1 bicycle space per 20 vehicle spaces required for commercial/retail/office/industrial/warehouse uses; fractions round up and the Planning Director can consider exemptions in special cases (§ 30‑21.3.g).

When is an off‑street loading space required, and what size must it be?

Separate off‑street loading is required for commercial/office/industrial/warehouse buildings exceeding 7,000 sq ft. Loading counts follow Table 30‑21.D (1 space for 7,001–20,000; 2 for 20,001–50,000; 3 for 50,001+); minimum loading stall dimension 12' x 25' and turning radii must keep maneuvers on‑site (§ 30‑21.10).

Can required parking be provided off‑site or in a different block?

Yes for nonresidential uses if the off‑site lot is within 300 feet of the lot perimeter, is in the same or an adjacent block (alley separation allowed), and the Planning Director approves; a recorded covenant is required to ensure long‑term maintenance (§ 30‑21.3.h.2).

Can I request fewer parking spaces for a large warehouse or industrial project?

Potentially — the Modified Parking Requirement (MPR) process applies to eligible industrial/warehouse projects on lots 10 acres or greater; an MPR requires a parking demand study (ITE or comparable surveys) and Planning Commission/City Council approval (§ 30‑21.12). MPRs do not apply to residential or commercial land uses.

What are the stall and aisle dimension standards I must show on plans?

Standard car stalls: 9' x 20'; parallel stalls 9' x 22'; compact stalls 8' x 16'. Aisle widths depend on orientation (see Table 30‑21.B; e.g., 25 ft two‑way for 90° stalls). Vertical clearance requirements are in Table 30‑21.C. Show these on plan view and sections (§ 30‑21.3.b; Tables 30‑21.B/30‑21.C).

Are there carpool, motorcycle or compact parking rules?

Yes — nonresidential parking must designate at least 10% of the total parking for carpools; facilities with 25 or more parking spaces must provide a designated motorcycle area (min 56 sq ft); up to 30% of spaces can be compact where allowed (§ 30-21.3.e–f and related provisions).

Can the Architectural Review Board or Planning Commission relax parking layout details?

The Architectural Review Board can approve minor modifications to parking design standards (per § 30‑21.11.a / § 30‑45), and variances may be needed for major modifications (§ 30‑21.11.b, § 30‑27). For big deviations consider a variance or MPR (if eligible).
