Vacaville — Parking

Last reviewed: July 2, 2026

Overview

This page summarizes what the City of Vacaville's Land Use and Development Code says (and does not say) about parking: definitions, where parking standards live in the Code, what triggers traffic/parking analysis, and how the Code treats off‑street, shared, and tandem spaces. It links you to the relevant parts of the Code that were available in the retrieved materials and flags the requirements I could not locate in those materials. The Code files retrieved were the City zoning/land‑use text (Title 14 / Division 14.09) and related local chapters; building / accessibility rules live in the California Building Standards Code.

Key takeaways (top line)

• The Code defines parking terms and says the Land Use and Development Code contains standards for parking lots and related site features — but the specific numerical parking ratios, bicycle parking table, and loading‑stall dimensions were Not found in the retrieved materials. See "Information Gaps" below for what to verify with the City. Definitions and procedural rules are present in the Code and cited below.

What the Vacaville Code actually contains (by topic)

• Definitions and measurement rules

  • Parking, off‑street, parking space, parking space, tandem, and parking, shared are defined in the Code's definitions chapter (Division 14.02). Use these definitions when preparing submittals. See § 14.02.050 for the definitions used across the title.
  • Rounding rules and measurement responsibilities (who provides scaled drawings and how to round fractional results when counting spaces, dwellings, etc.) are in the rules of measurement. See § 14.02.030.

• Development standards exist for parking and related site features

  • The Code explicitly states that the Land Use and Development Code includes development standards for parking lots, signs, landscaping, and other site features (i.e., parking standards are part of the development standards package), but the detailed numeric tables (parking ratios per use, bicycle parking counts, loading stall sizes) were not included in the retrieved excerpt. See § 14.01.030 (overview statement that these development standards are included in the Code).

• Traffic impact / when a project must analyze circulation and parking

  • Projects that generate significant traffic (the Code defines thresholds and the process for a traffic impact analysis and mitigation) may be required to study circulation and off‑site improvements; this is handled through the Traffic Impact Mitigation Ordinance. See § 14.13.180 (Traffic Impact Mitigation) for tests like “major project” thresholds and mitigation/reimbursement procedures. If the project will materially affect intersection or roadway LOS, traffic analysis and off‑site mitigation can be required.

• ADU (Accessory Dwelling Unit) parking — state law vs local code

  • The retrieved Vacaville materials identify the Director of Community Development handles ADUs administratively (the Code gives the Director authority over accessory dwelling units in administrative lists), but Vacaville‑specific numeric ADU parking exceptions/ratios were Not found in the materials I examined. State ADU rules (summarized in the ADU handbook included in the materials) require that local parking requirements for ADUs cannot exceed one space per unit or per bedroom (whichever is less) and list circumstances where ADU parking must be eliminated; these state rules are described in the ADU handbook summary. Verify Vacaville's local ADU parking implementation with the City.

• Accessibility and parking

  • Accessible parking space counts, dimensions, and placement are governed by the California Building Standards Code (Title 24) (not by local zoning numbers). Where the zoning code requires parking, the design and accessible stall details follow the State code. See the state building code references for accessible parking (e.g., Chapters 11A / 11B). For example, accessible‑stall tables and design requirements appear in the Building Code rather than the local zoning excerpts provided.

District‑by‑district breakdown (what the Code says about parking in each zoning district)

The Vacaville Land Use and Development Code (Title 14) organizes use and development rules by zoning district. The retrieved materials include the definitions and administrative rules and reference that development standards (which include parking) are part of the Code; however, the specific district‑level parking schedules and per‑district tables (for R‑1, R‑2, R‑3, C‑N, C‑1, C‑2, M‑1, M‑2, Planned Development, etc.) were Not found in the retrieved materials. The Code does identify that “Zone” is the term for zoning districts and that development standards (including off‑street parking) are regulated at the district level. For district‑by‑district numeric standards, Verify with the City.

Below are the district subsections you will typically expect to consult when researching a project in Vacaville; for each I show what the retrieved material says and what to verify:

R‑1 (single‑family residential)

• What the retrieved materials say: the Code defines parking terms and measurement rules; the Code lists that development standards (including off‑street parking) apply to residential districts. No numeric parking table for R‑1 is present in the retrieved files. Verify with the jurisdiction for required spaces, garage/tandem rules, and driveway allowances.

R‑2 / R‑3 (multi‑family residential)

• What the retrieved materials say: multi‑unit site planning is governed by the Code and parking/measurement rules apply; the City’s traffic impact provisions apply where multi‑unit projects trigger traffic thresholds. Specific parking ratios for multi‑family were Not found in the retrieved materials; accessible‑parking design follows the state Building Code. Verify with the jurisdiction for per‑unit parking requirements, guest parking, and bicycle parking.

C‑N, C‑1, C‑2 (commercial / neighborhood commercial)

• What the retrieved materials say: the Code treats nonresidential uses separately and includes nonresidential floor‑area/parking references in measurement rules (nonresidential floor area excludes areas used for off‑street parking). No district table for commercial parking ratios was found. Verify with the jurisdiction for per‑use parking standards and bicycle/short‑term parking requirements.

M‑1, M‑2 (industrial / manufacturing)

• What the retrieved materials say: the Code contains use classifications including “Commercial Parking Lots and Structures” and other industrial uses; specific loading and large vehicle parking standards were Not found in the retrieved materials. For loading stall dimensions and required on‑site truck turning radii, Verify with City Engineering standards and the building/fire code.

Planned Development (PD) / Overlays

• What the retrieved materials say: the City uses planned development overlays and may set site‑specific development standards for parking in an approved PD or specific plan; overlay/district exceptions are processed per the Code. Check the project's PD document or overlay map for parking modifications. See the code's overlay and PD procedures. Verify with the applicable PD or overlay ordinance.

Table: what is available vs missing (decision‑relevant)

Practical guidance for applicants (plain English)

• Always submit scaled, dimensioned site plans that show every proposed parking stall, aisle, curb cut, and bicycle rack; the Code requires applicants to provide drawings adequate for verification and rounding rules apply to fractional space counts (§ 14.02.030).
• Expect the Director of Community Development and the City Engineer to review parking, driveway locations, and circulation; for large projects the Planning Commission or City Council may be involved. See the Code’s authority and administrative lists (§ 14.01.030).
• If your project is large enough to be a “major project” (traffic generation thresholds are in the Traffic Impact chapter), the City may require a traffic/parking impact analysis and off‑site mitigation under § 14.13.180.
• For accessibility and the technical dimensions of accessible stalls, use the California Building Standards Code (Title 24); Vacaville’s zoning directs you to follow state accessibility requirements where applicable.
• For ADUs: the State ADU rules cap parking at one space per unit or bedroom in many circumstances—Vacaville’s local implementation of ADU parking was not located in the retrieved municipal files; verify with the City’s ADU handout or staff.

Checklist (what an applicant must supply / satisfy before City approval)

• Provide a scaled site plan showing all proposed off‑street parking stalls, aisles, driveways, and the number of spaces and show calculations used to arrive at the count; drawings must be adequate to allow verification by City staff (§ 14.02.030).
• Demonstrate how parking is sized against definitions in § 14.02.050 (tandem, shared, off‑street, etc.).
• For major projects, include a traffic impact analysis consistent with the Traffic Impact Mitigation Ordinance and any required mitigation measures (§ 14.13.180).
• Show compliance with state accessibility/Title 24 stall and circulation rules for accessible parking (design details live in the California Building Standards Code).
• Indicate bicycle parking, loading spaces, and EV readiness if applicable — confirm local numeric requirements with City staff if not shown on the Code exhibits provided here (not found in retrieved materials). Not found in retrieved materials.
• If your site is within an overlay or PD, include the PD/overlay parking standard or request a modification consistent with overlay procedures. Verify applicable overlay rules via the Vacaville Overlay Districts page.

Risks & Ambiguities

Plain‑English summary (for a homeowner)

The Vacaville Zoning Code defines off‑street parking (what a parking space, tandem stall, and shared parking mean) and requires you to submit scaled site plans and calculations; large projects must complete traffic/parking studies. However, the exact numeric tables for how many spaces are required per use or district (and bicycle‑parking tables) were not present in the materials I reviewed — you need to confirm those numbers with City planning staff. See the Code’s definitions and Traffic Impact chapter for rules on measurements and when studies are required.

Information Gaps (what I could not confirm from the retrieved materials)

• The precise per‑use, per‑district parking ratios (e.g., spaces per dwelling unit, per 1,000 SF retail, per seat for assembly uses) — Not found in retrieved materials. Verify the numeric parking schedule table in the full Code or ask City staff.
• The City’s specific bicycle parking counts and design standards (short‑term vs long‑term) — Not found in retrieved materials; the state CALGreen / Building Code provides bicycle parking guidance but local standards were not in the excerpt.
• Off‑street loading stall size and required number per use (truck bays, delivery areas) — Not found in retrieved materials.
• District‑level parking variations (R‑1 vs R‑2 vs commercial zones): per‑district tables not found. Verify with the City's official Code on the municipal website or planning counter.
