Vacaville Zoning, Planning & Building Codes

Last reviewed: July 3, 2026

Overview

Vacaville's land-use rules are codified as Title 14 / Division 14.09, Land Use and Development Code and implement the city's General Plan, the Subdivision Map Act and statewide standards (including the California Building Standards) to manage growth, protect public safety, and coordinate public improvements. The Code lays out how the city divides land into zones, the citywide development rules that apply to every project, discretionary review paths, and a set of policy tools—specific plans, planned-dev overlays and overlays—that alter baseline rules for focused areas. See the city’s statement of purpose and where the Code lives at § 14.01.010.010.

How Vacaville's code is organized

• The Code is arranged into Divisions and Chapters (definitions, procedures, development standards, special chapters such as subdivisions, grading, and environmental review). The basic identification of the title and purpose is in § 14.01.010.010 and the Code’s organization (divisions/chapters/sections) is described in the same chapter.
• Applicability rule: land, buildings and uses must follow the Code; permits cannot be issued unless the application complies with the Code and the General Plan—see § 14.01.020.010.
• Decision‑maker structure: City Council, Planning Commission, Director of Community Development, City Engineer, Building Official and Fire Chief are given specific authorities and appeal roles in Chapter 14.01.030 (§ 14.01.030.010 – § 14.01.030.040). That chapter lists which bodies hear zoning map amendments, planned development overlays and design guidelines.

Zoning district families (city‑level view)

Vacaville organizes regulated uses into zone areas shown on the official zoning map and controlled by the Land Use and Development Code. The Code defines zones and use classes; the use classification block (residential types, commercial, industrial, institutional, accessory uses, etc.) is in Chapter 14.02.060 (§ 14.02.060.010 – § 14.02.060.060). The Code defines “zone” (zoning district) in the Definitions chapter.

At a city‑wide level you will encounter the following families (how Vacaville uses them is governed by the chapters cited):

• Residential — single‑family, duplex, multi‑unit and accessory dwelling unit types are defined under use classifications in § 14.02.060.010; residential density and rules are implemented via zone designations and specific plan maps.
• Commercial — retail/service districts regulated by use‑classification and development standards in Division 14.09 and related chapters.
• Industrial — manufacturing/industrial zone families and performance standards appear in the use and development chapters (see Division 14.02–14.09).
• Mixed‑use — mixed use and downtown/mixed areas are handled by zone designation and, where adopted, specific plan or policy plan rules. See the General Plan and Chapter guidance in Division 14.04 and 14.09.
• Planned Development / PD overlays — the City explicitly authorizes Planned Development overlays, including with a density bonus, as an approval tool (City Council/Planning Commission role described in § 14.01.030.). These are used to customize standards for larger projects.
• Specific plans / policy plans — where an area has a Specific Plan or Policy Plan, those documents override and detail standards for that area; adoption and amendment are City Council actions (see § 14.01.030 and Chapters on specific/policy plans).
• Overlay Districts — the Code uses overlays for issues such as flood zones, airport‑influence area referral rules, and historic districts; overlay rules are implemented in the relevant chapters (e.g., floodplain rules in Chapter 14.18). See the Code’s definition of zone and overlay treatment in the definitions and special chapters.

Note: the Code refers to the “official zoning map” as the map that places parcels into these zones; the Code’s definitions and mapping rules are in the Definitions and Zoning Map chapters.

Citywide development standards — what lives where

• Setbacks, height, lot coverage, FAR and how to measure them: the Code defines FAR and lot coverage concepts and measurement rules in the Definitions and measurement chapters (see § 14.02.030.080 for FAR definitions/exclusions and related measurement rules). Specific numeric standards by zone are implemented in the development standards tables in Division 14.09 (development‑standards tables and site standards).
• Setback rules and “future street” setbacks/alleys: special rules for measuring and when setbacks are established from a future right‑of‑way are in § 14.09.200.030 (see requirements about planned street expansions and alley rules).
• Parking: the Code includes off‑street parking and related standards in the development standards division; the Code also contains the technical measurement and administrative rules for parking. For local parking rules consult the parking chapter and the city's development standards tables. See the Code’s overall development rules and the chapter titles that implement parking standards. For where parking standards live in the Code, consult the development standards division and parking chapter(s). (See the Vacaville Parking page for navigation to those tables.)
• Landscaping, screening, and signs: the Code treats landscape, screening and sign standards as stand‑alone chapters and includes implementing diagrams (see Division references for landscaping/screening and Chapter on signs).

Practical note: the Code contains definitions of how FAR and lot coverage are calculated and what features are excluded (for example eaves, unenclosed porches, small accessory structures) — see § 14.02.030.080. Numeric, zone‑specific values (e.g., “R‑1 front yard = X ft; maximum height = Y ft; lot coverage = Z%”) are set in the zone tables and in any applicable specific plan or Planned Development approvals (those zone tables and specific plan chapters should be checked for the parcel you are working on).

(Links to the site’s navigation for development standards, landscaping and screening, and signage are helpful first stops.)

Specific plans & overlays

• Specific Plans / Policy Plans: adoption, amendment and scope for Specific Plans are handled as legislative actions (Planning Commission recommendation and City Council adoption) — see the Code authority listing in Chapter 14.01.030 and the General Plan / Specific Plan chapters.
• Overlays that commonly matter in Vacaville include the floodplain rules (Ch. 14.18 — flood standards and variances), the airport influence referral requirement to the Solano County Airport Land Use Commission (see § 14.09.110.070), and historic designation rules where applicable. The Code places flood rules and variance criteria into Chapter 14.18 and requires referrals for airport‑influence area map amendments.
• Planned Development overlays and development agreements are specific legislative tools; the Code allows development agreements and PD overlays for projects that provide substantial public benefits (see the Development Agreement Division and Planned Growth / PD references in Chapter 14.17 and § 14.17.010.010).

Building permits & review: the typical paths

• Administrative (ministerial) approvals: the Director of Community Development has delegated administrative authority for items such as home occupations, accessory dwelling units, design review (administrative types), minor use permits, parcel maps and certain signs — see the list of Director authorities in Chapter 14.01.030. For example, accessory dwelling units are listed as within the Director’s authority for administrative approval.
• Planning Commission / City Council discretionary approvals: Conditional Use Permits, Variances, Design Review (major), Tentative Maps and major modifications are typically reviewed by the Planning Commission (and appealed to or decided by City Council for legislative matters) — see Chapter 14.01.030 and the procedures in Chapter 14.09.030 (application, notice, hearings, appeals).
• Subdivisions / parcel maps: the subdivision map rules and required map types (tentative map, parcel map, final map) appear in Chapter 14.11, including Table 14.11.010.A and Table 14.11.010.B that assign decision‑makers and map requirements. Permit issuance is tied to map approval and completion of improvements or improvement guarantees.
• Improvements & public infrastructure: standard public improvement requirements, improvement agreements, deferrals or supplemental improvements are governed by Chapter 14.12 (Standard Improvements and Plan Lines). Street and transit improvement obligations and timing are set there.
• Design review process and guidelines: the City may adopt design guidelines by resolution and the Planning Commission’s role in design review is spelled out in the Code; design‑sensitive projects are captured by the design review chapters and the authority tables. See § 14.01.030 for who administers design review and the authorization for Council to adopt design guidelines.

If you need to track a permit application: start with the procedural chapter Chapter 14.09.030 (application, completeness, public notice, hearings and appeal steps) and the decision‑maker table in Table 14.11.010.B for who will hear map/land‑use applications.

State housing law in Vacaville — interplay and practical points

• ADUs / JADUs: the Code defines accessory dwelling units under the use classifications (see Chapter 14.02.060) and the Director is authorized to process Accessory Dwelling Units administratively (see the Director authority list in Chapter 14.01.030). When processing ADUs, Vacaville must also follow state ADU laws (e.g., Ministerial 60‑day action windows, parking limits, size/height constraints under state law). The Code provides the local permit path but ADU applicants must expect the Code’s rules to be interpreted consistent with state ADU statutes; see the Code’s ADU definitions and administrative authority in § 14.02.060.010 and Director authority in Chapter 14.01.030.
• SB 9 / lot splits & ministerial small‑lot laws: Vacaville’s subdivision chapter implements parcel map, lot line adjustment and urban lot split procedures consistent with the Subdivision Map Act; the Code’s subdivision chapters describe when parcel maps or tentative maps are required and link to state statutory requirements (see Chapter 14.11 and Table 14.11.010.A for urban lot split/parcel map requirements). Local implementation must still conform to state SB 9 procedural constraints where applicable.
• Density bonus (Government Code 65915): Vacaville explicitly implements density bonus rules and allows density increases as part of planned‑development processes; see the Code’s references to “density bonus” as applied to planned development overlays and density bonus procedures in the Code (see § 14.01.030 and the Code references to density bonus provisions).
• Rent control: Vacaville’s Code and the chapters provided do not create a local rent‑control regime; the Code addresses land‑use approvals and not imposing rent regulation. Confirm rent‑control status with the Municipal Code and local ordinances outside Title 14 if needed. Not found in retrieved materials — verify with the city clerk/municipal code. (See “Information gaps” below.)

For more about ADUs and how state ADU law limits local rules, consult the Code provisions for ADUs and the state ADU summary in the city’s permitting guidance (local ADU approvals are listed among Director authorities) § 14.02.060.010 and Chapter 14.01.030. (Also see the state ADU summaries in the uploaded ADU reference.)

Information Gaps / What to check next

• Parcel‑level numeric standards (the zone tables showing exact numeric setbacks, heights, lot coverage and parking minima by zone) were not visible in the retrieved snippets. These numeric values are typically presented in Division 14.09 development standard tables or within a parcel’s Specific Plan; check the official zone table in Division 14.09 or the applicable specific plan for the parcel. Not found in retrieved materials; verify by consulting the Code’s Division 14.09 development‑standards tables or the City’s online zoning map.
• Any recent local amendments or adopted design guidelines adopted by City Council after the date of the material retrieved here: the Code allows Council to adopt design guidelines by resolution; check the City Council resolutions and the City planning web pages for anything newer than the ordinance snapshots in these files.
