Irwindale — Parking
Parking under the Irwindale local zoning and planning code, with the controlling citations.
Last reviewed: July 2, 2026
Overview
This page summarizes how the City of Irwindale regulates off‑street parking, loading, and bicycle parking in the local zoning code (Title 17). It pulls the governing rules from the Irwindale zoning chapters that control parking counts, special district rules, joint/shared parking, and development‑scale bicycle/TDM measures, and notes where the code defers discretion. For related topics see the citywide Irwindale zoning & planning overview, Irwindale Zoning, and Irwindale Development Standards.
What the code says (top lines)
- Off‑street parking is required for new buildings, changes of use, enlargements, and additions; both motor vehicle and bicycle parking are covered. See § 17.64.020 .
- The code provides a use‑by‑use parking schedule in § 17.64.030 (matrix of ratios for assembly, retail, offices, dwellings, manufacturing, warehousing, etc.) .
- The Planning Commission can authorize joint use/reciprocal parking under specified conditions (distance, hours of operation, recorded agreement) per § 17.64.070 .
- Applicants must show parking on submitted plans (location, dimensions, striping), and parking plans are reviewed with building permit/site plan submittals per § 17.64.090 and project submittal checklists such as those in the site‑plan requirements (see § 17.70.070 referenced in the submittal list) .
- Bicycle parking and employer trip‑reduction measures are required at larger nonresidential developments (e.g., bike racks per square‑foot thresholds and preferential carpool/vanpool spaces) — see the transportation/TDM chapter requirements captured in § 17.66 (requirements for bicycle racks, carpool spaces, transit/bus stop improvements) .
- Accessory dwelling units (ADUs) are subject to Chapter 17.120 but the city caps ADU parking at no more than one space per unit or per bedroom (whichever is less), and allows tandem driveway parking — § 17.120.050 .
For design/appearance rules that interact with parking areas (landscaping, screening, lighting), the design and landscaping chapters require parking areas be landscaped and screened consistent with site design standards; see the design guidelines and landscaping requirements in the main code (examples: § 17.56/17.80 design guidance) .
District‑by‑district (what the code actually shows)
Note: the code includes many zone chapters. Below are the districts for which parking rules or explicit standards are present in the retrieved materials. All quoted requirements are grounded in the cited §.
R-1 (single‑family residential)
- Purpose / typical uses: single‑family homes (standard R‑1 development standards in Chapter 17.16). See § 17.16.030–050 for permitted uses and development limits .
- Parking rule: two (2) off‑street parking spaces per dwelling unit, to be located in a garage on the same lot — § 17.16.100 .
- Key dimensional/related standards: height limit two stories / 35 ft (maximum) — § 17.16.090; accessory buildings and driveway placement rules affect where parking may be sited — § 17.16.110 .
- Where it applies: residential parcels zoned R‑1. For ADU exceptions, see § 17.120.050 (ADU parking limit) .
M-1 (light manufacturing)
- Purpose / typical uses: light industrial/manufacturing. The code treats recycling, manufacturing, and similar uses specially in multiple chapters (see § 17.56 and § 17.64 references) .
- Parking rule: the general parking schedule in § 17.64.030 applies (manufacturing parking is computed as parking for vehicles used in conjunction with the business plus employee ratios — see § 17.64.030(K)) .
- Where it applies: parcels zoned M‑1. Recycling/processing uses in M‑1 face conditional use and amortization requirements tied to parking adequacy — see § 17.56.090 .
M-2 (heavy manufacturing)
- Purpose / typical uses: heavier industrial uses requiring more controls (Chapter 17.100 is an overlay/zone chapter for M‑2 uses) .
- Parking & circulation: specific M‑2 rules require (among other items) minimum spacing/size and maintenance of parking. Examples from the M‑2 chapter:
- Off‑street parking rate expressed per lot area for certain operators and minimum spaces per operator — § 17.100.070(A–B) .
- Minimum parking stall size called out as 9 ft × 19 ft for M‑2 parking § 17.100.070(E) .
- All loading/unloading must be on‑site and not in the public right‑of‑way § 17.100.070(J) .
- Where it applies: parcels zoned M‑2 and properties subject to the heavy‑manufacturing standards (note: certain uses in M‑2 still require CUPs and special conditions) .
Q (Quarry) and special use overlays
- Purpose / typical uses: quarrying and resource extraction; the code treats certain sensitive or special uses differently and permits some adult‑oriented businesses only in M‑2 and Q per § 17.59.030 .
- Parking: the code does not show a separate Q‑specific parking matrix in the retrieved snippets; instead, the general § 17.64.030 schedule and overlay conditions/control (e.g., CUP, operational conditions) apply — Verify with the jurisdiction for Q‑specific interpretations (Not found in retrieved materials).
City‑wide / special rules that cut across districts
- Mixed uses must provide the sum of required parking for each use — § 17.64.060 .
- Joint/reciprocal parking can be approved (limits on distance 150 ft, operating hours non‑conflict, recorded agreement) — § 17.64.070 .
- ADUs: off‑street parking for an ADU is capped — at most one (1) parking space per unit or per bedroom, whichever is less; tandem driveway parking is allowed — § 17.120.050(A) .
- Density bonus housing may use alternative, reduced parking ratios under the city's density bonus rules (Table of bedroom → parking in § 17.15.060) .
- Large nonresidential projects must provide preferential carpool/vanpool spaces and bicycle parking by size thresholds (bike rack standard: 4 bicycles per first 50,000 sq ft, plus 1 per additional 50,000 sq ft) — see § 17.66 / TDM rules .

Checklist (what an applicant must supply / satisfy)
- Show off‑street parking count and calculations that use the city matrix (or demonstrate comparable use if not listed) — § 17.64.030 / § 17.64.040 .
- Site plan that labels: location and number of off‑street spaces, striping/dimensions, curb cuts, internal circulation, loading spaces, and handicapped spaces — § 17.64.090 and project submittal checklist items (site plan requirements) .
- If proposing shared/joint parking, submit recorded legal instrument and show compliance with 150 ft distance and non‑conflicting hours — § 17.64.070 .
- For ADUs, show ADU parking does not exceed 1 space per unit/bedroom and if using tandem parking, indicate how tandem access will be provided — § 17.120.050 .
- For large nonresidential projects, include TDM measures: carpool/vanpool preferential spaces, bike racks per thresholds, transit/bus stop improvements as applicable — § 17.66 .
- For M‑2 or special industrial uses, show parking stall dimensions, drive aisles, loading area locations and that all loading/unloading occurs on‑site — § 17.100.070 .
- Provide any landscape/screening for parking areas required by site design or overlay conditions — see design/landscaping guidance (various sections) .
- If the use is not listed in the matrix, provide a justification and traffic/parking data for an alternative requirement — § 17.64.020(I) .
Risks & Ambiguities
| Issue | Why it matters | What to verify |
|---|---|---|
| Use not listed in matrix | City approves parking for unlisted uses on a case‑by‑case basis; this can delay approvals or add conditions | Confirm whether your specific use matches an existing matrix entry or will require a planning determination — § 17.64.040 |
| ADU driveway / tandem interpretation | ADU parking may be provided tandem, but how this interacts with local driveway setbacks and front‑yard rules may vary | Verify driveway location/encroachment rules and whether tandem parking is acceptable on your parcel — § 17.120.050 |
| Stall dimensions outside M‑2 | M‑2 explicitly states 9×19; the general chapter does not always restate stall size for every zone | Confirm required stall/aisle dimensions with staff — code shows 9 ft × 19 ft in M‑2 (§ 17.100.070(E)) but general dimensions elsewhere may be implicit or subject to engineering approval — § 17.100.070(E) |
| Joint/shared parking legal instrument | Joint parking needs a recorded instrument; failure to record may void the arrangement | Prepare a recorded agreement reviewed by City Attorney as required by § 17.64.070(D)(3) |
| Overlay / CUP conditions (e.g., recycling or dismantling yards) | Overlays (M‑2 auto‑dismantling, recycling) carry extra parking/operating conditions and time limits | Check overlay chapter and CUP conditions — e.g., Chapter 17.100 and § 17.56.090 for recycling amortization and CUP findings on parking adequacy |
| Bicycle parking sizing for smaller projects | Bike rack thresholds apply at large thresholds (50,000 sq ft); small projects may have no quantified bike requirement | Confirm bicycle parking expectations for projects below thresholds — § 17.66(B)(2) |
Plain‑English summary
If you build or change a use in Irwindale you must provide off‑street parking per the city’s Title 17 parking tables (or get an approved alternative). Single‑family homes need 2 spaces/unit; ADUs are limited to 1 space/unit or per bedroom; large nonresidential projects must provide bike parking and carpool spaces; joint use is possible but requires a recorded agreement and proximity limits. See the specific code sections listed below to match your use and zone. Verify ambiguous or parcel‑specific items with City planning staff. Key code anchors include § 17.64.020, § 17.64.030, and § 17.120.050 .

Frequently asked questions
How many parking spaces are required for a single‑family home in Irwindale?
Each single‑family dwelling in the R‑1 zone must provide two (2) off‑street parking spaces on the same lot (in a garage) — § 17.16.100 .
What is the city’s base source for parking ratios for commercial/industrial uses?
The city’s parking matrix in § 17.64.030 lists ratios by use (retail, restaurant, manufacturing, warehousing, assembly, etc.) and is the starting point for calculating required stalls — § 17.64.030 .
Can I use another project’s parking lot to meet my requirement (shared parking)?
Yes — the Planning Commission may authorize joint/reciprocal parking subject to conditions (e.g., up to 50% offset in many cases, maximum 150 ft distance between uses, recorded agreement) — § 17.64.070 .
Do ADUs in Irwindale have their own parking requirement?
ADU parking is limited: the city will not require more than one parking space per ADU or per bedroom (whichever is less); tandem driveway spaces are allowed — § 17.120.050(A) .
Are bicycle racks required?
Yes for larger nonresidential developments: bicycle parking is required (for example, 4 bicycle spaces per first 50,000 sq ft and 1 per each additional 50,000 sq ft), and TDM measures such as carpool spaces are required for large projects — see § 17.66 (TDM/bicycle provisions) .
Where do I show parking on my permit submittal?
Show parking location, number of spaces, space dimensions, striping, internal circulation, handicap spaces and loading areas on the site plan submitted with your building permit/site application — required by § 17.64.090 and the application submittal list (project checklist) .
If my use isn’t in the matrix, how will parking be decided?
The approval body (planning staff/commission) determines parking for uses not listed, using requirements for similar uses and relevant traffic/engineering data — § 17.64.020(I) and § 17.64.040 .
Are stall sizes standardized?
The M‑2 heavy‑manufacturing chapter explicitly requires parking stalls of at least 9 ft × 19 ft in that zone (§ 17.100.070(E)). For other zones, stall and aisle dimensions are addressed in site/engineering review — verify with city engineering — § 17.100.070(E) .
Do density bonus projects get different parking rules?
Yes — the density bonus chapter allows projects that request the density bonus to use alternative parking ratios (see density bonus parking ratios in § 17.15.060) — § 17.15.060 .
Must loading/unloading happen on‑site?
Yes — Irwindale requires that all loading/unloading take place on‑site and not in the public right‑of‑way — see general parking/circulation requirements and M‑2 rules (e.g., § 17.100.070(J)) .
