Last reviewed: July 2, 2026

Overview

Gilroy’s land-use rules are codified primarily in Chapter 30 of the Gilroy City Code (the zoning ordinance). The ordinance organizes the city into base districts and combining/special districts, and then controls what uses are allowed by referring users to two central use-summary tables: the residential use table (referenced at § 30.11.10(c)) and the commercial use table (referenced at § 30.19.10). Site and dimensional rules are applied by cross-reference to the residential and commercial site and building requirement tables (see § 30.11.20(c) and § 30.19.20) rather than repeating numbers in every district article. (§ 30.7.20; § 30.15.20)

Note: when this page mentions parking, design review, overlay districts, ADUs, development standards, and the California Building Standards Code, those terms are linked to Gilroy reference pages where the city groups related procedural/technical materials: the first time each topic appears it is a link to the internal menu item named below.

How the ordinance is structured (quick primer)

  • The ordinance gives each base district a short “statement of intent,” then says the district’s permitted and conditional uses are set by the citywide use tables (residential or commercial). Example: the R3 and R4 residential districts both point to § 30.11.10(c) for allowed uses; the C1, C3, HC, PO, CM, and downtown districts point to § 30.19.10 for commercial uses. (§ 30.7.20; § 30.8.20; § 30.13.20; § 30.15.20; § 30.16.20; § 30.12.20; § 30.17.20)

  • Dimensional and site rules are consolidated into the residential site and building requirement table and the commercial site and building requirement table; districts reference those tables for setbacks, heights, lot coverage, etc. (§ 30.11.20(c); § 30.19.20)

  • Conditional uses and the process to obtain them are handled by the conditional-use permit rules in § 30.50.30 (referenced repeatedly in district articles). (See multiple district entries such as § 30.15.20 and § 30.16.20.)

  • Practical permit triggers and design controls—such as architectural and site review, downtown-specific permits, and planned unit development—are located in the ordinance and in district-specific sections; these are cited below where applicable.

District-by-district summary (Gilroy-specific)

Each subsection below names the official district title (bold), the controlling code references, the stated purpose, where to find the permitted/conditional uses, and the most decision-relevant dimensional or programmatic requirements that the ordinance text either specifies or points you to.

A1 — Agricultural district

  • Purpose: The A1 Agriculture district is intended to protect land used for agriculture while anticipating future urbanization. (§ 30.4.10)
  • Permitted/conditional uses: Uses are governed by the residential use table at § 30.11.10(c); conditional uses may be approved under § 30.50.30. (§ 30.4.10(b))
  • Dimensional/other rules: The A1 district’s site and building rules point to the residential site and building requirement table (§ 30.11.20(c)). Density limitation: maximum of one dwelling unit per lot; overall aim of <1 unit/20 acres average. (§ 30.4.10(d))
  • Where used: Outlying agricultural parcels inside city limits and areas intended for eventual urbanization. Verify parcel-specific constraints in the table at § 30.11.20(c).

RR — Rural Residential district

  • Purpose: The RR Rural Residential district provides for part‑time farming and the keeping of livestock pending future urbanization. (§ 30.4.20)
  • Uses: Governed by § 30.11.10(c) (residential use table); conditional uses via § 30.50.30. (§ 30.4.20(b))
  • Dimensional/other rules: Site/building rules refer to § 30.11.20(c). Not all numerical setbacks for RR appear in the retrieved excerpts—verify with the site table. Not found in retrieved materials.

ND — Neighborhood District

  • Purpose: The ND Neighborhood District aims to create walkable neighborhoods with a mix of densities and neighborhood-serving services. (§ 30.10.10)
  • Uses: The ND relies on master plans or specific plans for each neighborhood area; permitted/conditional mixes are controlled by those plans and § 30.10.20 (see master plan language). (§ 30.10.20)
  • Dimensional/other rules: Mixed densities and neighborhood-serving commercial are encouraged; specific setbacks/density are in each neighborhood master plan (not repeated in the excerpt). Verify master plan.

RH — Residential Hillside district

  • Purpose: The RH Residential Hillside district is a special district for slopes generally >10% and <30%, designed to protect views, natural terrain, and limit hillside impacts. (§ 30.9.10)
  • Uses: Uses follow the residential use table (§ 30.11.10(c)); PUDs are commonly required and RH parcels are often subject to § 30.50.50 planned unit development rules. (§ 30.9.20)
  • Dimensional/other rules: Where PUD is not required, setbacks default to R1 standards; building height rules are explicit: normally limit to 30 ft, with stricter 15 ft limits where a roof peak would be within 20 ft of the ridge line; no silhouette against skyline allowed. (§ 30.9.30(a),(b))
  • Practical note: architectural and site review or PUD approval is the typical control. Verify with planning director.

R3 — Medium Density Residential

  • Purpose: The R3 Medium Density district accommodates multifamily housing (garden apartments, condos) aimed at 8–16 dwelling units/acre. (§ 30.7.10)
  • Uses: Uses are listed in the residential use table (§ 30.11.10(c)). Conditional uses follow § 30.50.30. (§ 30.7.20)
  • Dimensional/other rules: Maximum density stated as one dwelling unit per 2,722 sq ft (i.e., about 16 units/acre); additional site design requirements (private fenced yards for ground-floor units, multifamily design policy) are in § 30.7.50. (§ 30.7.40; § 30.7.50)

R4 — High Density Residential

  • Purpose: The R4 High Density district is for higher-intensity group dwellings and apartments (20–30 du/acre), located near high‑capacity streets and services. (§ 30.8.10)
  • Uses: Governed by § 30.11.10(c); conditional uses via § 30.50.30. (§ 30.8.20)
  • Dimensional/other rules: Minimum site area per unit ranges 1,452–2,178 sq ft per dwelling (see § 30.8.40). Multifamily developments must follow the adopted multifamily residential design policy. (§ 30.8.40; § 30.8.50)

PO — Professional Office district

  • Purpose: The PO Professional Office district allows lower‑intensity office and professional uses. (§ 30.12.20)
  • Uses: Uses directed to the commercial use table (§ 30.19.10). (§ 30.12.20)
  • Dimensional/other rules: Site/building requirements administered through the commercial site and building requirement table (§ 30.19.20).

C1 — Neighborhood Commercial district

  • Purpose: The C1 Neighborhood Commercial district is for low‑intensity, neighborhood-serving businesses compatible with residential areas. (§ 30.13.10)
  • Uses: Follows § 30.19.10 commercial use table; conditional uses permitted via § 30.50.30. (§ 30.13.20)
  • Dimensional/other rules: Site and building requirements governed by § 30.19.20.

C3 — Shopping Center Commercial district

  • Purpose: The C3 Shopping Center Commercial district is for high‑intensity, citywide/regional commercial uses; focuses on large setbacks, significant parking and landscaping. (§ 30.15.10)
  • Uses: Uses listed at § 30.19.10; conditional uses via § 30.50.30. (§ 30.15.20)
  • Dimensional/other rules: Site and building requirements via the commercial requirement table (§ 30.19.20) which also identifies where parking and landscaping rules apply. (§ 30.15.30; § 30.19.20)

HC — Highway Commercial district

  • Purpose: The HC Highway Commercial district serves visitor-oriented uses with immediate freeway access; parking and landscaping emphasized. (§ 30.16.10)
  • Uses & standards: Uses per § 30.19.10; site/building rules via § 30.19.20. Conditional uses via § 30.50.30. (§ 30.16.20; § 30.16.30)

  • Dimensional/other rules: See § 30.19.20 for site/building rules.

Downtown Specific Plan Districts (DHD, DED, CCA, TD, CD, GD)

  • Purpose: Downtown districts like DHD Downtown Historic District encourage mixed-use, pedestrian-focused, historic‑style development; some downtown districts have special rules (e.g., ground-floor active uses, limits on street-front parking). (§ 30.14.10)
  • Uses: Downtown uses are set in § 30.19.10 and further clarified with downtown-specific footnotes (e.g., residential units permitted above ground floor, limits on standalone new single‑family in DHD). (§ 30.14.11; see footnotes in § 30.19.10 table)
  • Dimensional/other rules: The commercial site and building requirement table (§ 30.19.20) and downtown subarticles (e.g., § 30.14.64 railroad corridor rules) set site controls. Examples: no street-front parking at retail in DHD; special rules for large dance venues and alcohol licensing are noted in the footnotes to the use table. (§ 30.14.10; § 30.19.10 footnotes)

OS — Open Space district

  • Purpose: The OS Open Space district protects land for agriculture, conservation, recreation, and scenic resources. (§ 30.24.10)
  • Uses: The ordinance lists specific permitted agricultural and conservation uses; many recreational and institutional uses are conditional and require a conditional use permit. (§ 30.24.20)
  • Dimensional/other rules: New buildings must be directly related to open-space use and are subject to architectural and site review; erosion control and grading rules apply. (§ 30.24.30)

  • Purpose & uses: The Hecker Pass special district defers use and dimensional specifics to its specific plan (e.g., agricultural and residential use tables in the Hecker Pass specific plan). (§ 30.29.20)
  • Dimensional/other rules: Minimum site and other site-building standards are in the Hecker Pass specific plan tables (Table 7‑1, 7‑2). (§ 30.29.30)

Glen Loma Ranch Special Use district

  • Purpose & uses: The Glen Loma Ranch special district establishes mixed densities and a neighborhood framework consistent with the Glen Loma Ranch specific plan; permitted uses are in the specific plan and the local ordinance cross-references it. (§ 30.30.10; § 30.30.20)

Industrial districts (CI / M1 / M2)

  • Uses: The industrial use table shows which industrial activities are allowed in CI, M1, and M2; many industrial and semi-public uses are listed with conditional/permitted designations (see the industrial use table snippets and footnotes). (See industrial tables)

Representative decision-relevant table (selected uses across key districts)

Use (typical) C1 Neighborhood Commercial C3 Shopping Center DHD Downtown Historic R3 Medium Density Code Reference
Retail (general) X (permitted via commercial table) X X (with downtown footnotes; street-level restrictions apply) C on ground floor; residential table governs § 30.19.10; downtown footnotes in § 30.19.10
Multifamily housing C (where allowed/per table) C / allowed as mixed use Allowed above ground floor; ground-floor residential restricted; minimum densities apply X (primary use) § 30.11.10(c); DHD notes § 30.14.11
Auto repair/sales C (conditional where indicated) X (in C3 per table) Some auto-related uses limited in DHD (footnote limits) Not a residential use § 30.19.10 footnotes
Parks / public facilities C (neighborhood-serving) C C X (neighborhood parks) District intent sections (e.g., § 30.10.10, § 30.25.10)

Key: X = unconditionally permitted by use table; C = conditional use; specific footnotes and downtown permits may alter ground-floor or proximity rules. See the commercial use table § 30.19.10 and residential use table § 30.11.10(c) for full lists and footnotes.

How the code handles special situations (quick guidance)

  • Conditional uses: The ordinance repeatedly states that conditional uses are allowed only by a conditional use permit issued under § 30.50.30 (referenced in district articles such as § 30.15.20, § 30.16.20, § 30.7.20). Always cite § 30.50.30 when preparing a conditional-use application.
  • Planned Unit Development (PUD) and hillside exceptions: In RH and certain combining districts, PUD approval via § 30.50.50 is required; small custom houses may use architectural/site review if they meet guidelines (§ 30.9.70). (§ 30.9.10; § 30.9.70)
  • Downtown special permits: Downtown-specific rules (e.g., administrative downtown use permits, limits on certain ground-floor uses, and downtown special-use permits) are embedded in the downtown articles and in use‑table footnotes; read § 30.14 subarticles and the footnotes in § 30.19.10 carefully.
  • Nonconforming uses: Nonconforming uses and limitations on expansion/discontinuance are governed by Article XLVIII (§ 30.48.10 et seq.); expansions of nonconforming uses are tightly constrained (e.g., 10% limit without variance). (§ 30.48.10; § 30.48.20)

Checklist (what an applicant must satisfy before filing)

  • Confirm the base zoning for the parcel and the applicable district article (e.g., R3, C3, DHD) and note the district intent. (See the relevant district article—e.g., § 30.7.10, § 30.15.10, § 30.14.10)
  • Determine whether your proposed activity is a permitted use, a conditional use, or a prohibited use using the residential use table (§ 30.11.10(c)) or the commercial use table (§ 30.19.10).
  • Check site and building standards (setbacks, heights, lot coverage) in the residential site and building requirement table (§ 30.11.20(c)) or the commercial site and building requirement table (§ 30.19.20).
  • If a conditional use or variance is required, prepare findings consistent with § 30.50.30 (conditional uses) or the variance provisions (see the city’s variance rules). Verify procedural submittal requirements. Not all procedural numbers reproduced here—verify with the planning division.
  • Confirm whether design or site review is required (downtown, hillside, special plans). If so, follow the architectural and site review procedures (see the ordinance and the city’s design-review page). Link: Gilroy Design Review.
  • Confirm parking requirements and landscaping/screening triggers in the commercial site table and Article XXXI (off‑street parking). Link: Gilroy Parking.
  • If within a combining/historic/overlay district, read the combining district article (e.g., historic combining district § 30.27.20) and the downtown special rules; consult § 30.27 for historic combining district permit findings. Link: Gilroy Overlay Districts; Gilroy Historic Preservation.

Risks & Ambiguities

Issue Why it matters What to verify
Downtown ground-floor vs. upper-floor uses Downtown footnotes allow many uses above the ground floor but restrict some at street level (e.g., some residential and parking rules). Projects that put the “wrong” use at sidewalk level can be denied or require a downtown permit. Read downtown footnotes in § 30.19.10 and § 30.14.11; verify with planning staff.
Missing numeric setbacks/dimensions in district articles Many district articles point to the site/building tables rather than listing numbers. If you assume a setback, it may be wrong. Consult § 30.11.20(c) (residential site table) and § 30.19.20 (commercial site table). If tables not present in your copy, request the official tables from the City Clerk or planning staff.
Nonconforming use expansion limits The ordinance restricts enlargement (10% without minor deviation; up to 25% only with variance). Misreading this can lead to illegal expansions. Confirm limits in § 30.48.20 before planning changes.
Footnote exceptions (e.g., alcohol, auto sales, dance venues) The commercial use table contains many footnotes that add distance limits, special approvals, or caps (e.g., large downtown dance venues). Missing a footnote can derail approvals. Review the footnotes in § 30.19.10 and related downtown articles (e.g., § 30.14).
Special plans override (Hecker Pass, Glen Loma Ranch) Special-use districts direct you to a specific plan for uses and standards; relying only on Chapter 30 can miss plan-specific constraints. Read the Hecker Pass or Glen Loma Ranch specific plan tables mentioned in § 30.29.20 / § 30.30.10.

Plain-English Summary

Gilroy’s zoning code assigns every parcel to an official district (for example R3, C1, DHD) and then tells you to look at a citywide use table (residential or commercial) to know whether your idea is allowed, conditional, or prohibited; site dimensions (setbacks, heights) are set by the residential or commercial site tables. Many important exceptions (downtown footnotes, hillside PUD rules, historic combining district findings) are buried in footnotes or separate special‑plan documents, so read the cross‑references carefully and verify with the planning division. (§ 30.11.10(c); § 30.19.10; § 30.11.20(c); § 30.19.20)

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

Frequently asked questions

What can I build on an R-1 lot in Gilroy?

The ordinance text provided to me points residential districts to the residential use table (§ 30.11.10(c)) and the residential site and building requirement table (§ 30.11.20(c)). The specific R‑1 article and its numeric setbacks were not included in the retrieved excerpts, so confirm the exact R‑1 permitted uses and setbacks by checking § 30.11.10(c) and the R‑1 article in the official code or with planning staff. Not found in retrieved materials for R‑1 specifics.

What are Gilroy setback requirements?

Most district articles point to the consolidated site and building requirement tables: the residential site and building requirement table (§ 30.11.20(c)) and the commercial site and building requirement table (§ 30.19.20). The numeric table entries were not visible in the excerpts I received, so verify the exact front, side, and rear setbacks by consulting those tables in the official municipal code or city planning staff. Not found in retrieved materials for specific table cells.

Do I need a conditional use permit to operate X business in a commercial district?

District articles uniformly state that conditional uses are governed by the commercial use table (§ 30.19.10) and that conditional uses are processed under § 30.50.30. Check the commercial use table’s line for your use; if it shows “C” or has a limiting footnote you’ll need a conditional use permit and to satisfy the findings in § 30.50.30.

Are residential units allowed downtown in Gilroy?

Yes—downtown districts (for example DHD) encourage mixed‑use and allow residential units, typically above the ground floor, but downtown footnotes impose restrictions (e.g., ground-floor residential often requires a conditional use or is disfavored). See § 30.14.11 and the downtown footnotes in § 30.19.10; verify minimum downtown densities and any ground-floor restrictions for your block.

What about hillside (RH) projects—are there special rules?

Yes. The RH district requires sensitivity to slopes and views; many RH projects require Planned Unit Development (PUD) approval under § 30.50.50 and have strict height/silhouette controls (e.g., 30 ft maximum, with a 15 ft limit near ridge lines). See § 30.9.10–30.9.30.

Where are the permitted use tables I need to check?

- Residential uses: § 30.11.10(c) (residential use table). - Commercial uses: § 30.19.10 (commercial use table) including downtown footnotes. Both are cross‑referenced by nearly every district article; if the printed tables are missing from your copy of the code, request the full municipal code PDF or ask planning staff.

Can a nonconforming business expand its building or floor area?

Nonconforming uses are allowed to continue, but expansion is limited: up to 10% of gross floor area by right (with conditions), and up to 25% only with an approved variance. Discontinuance rules also apply if a nonconforming use stops for more than 120 days. See Article XLVIII (§ 30.48.10 and § 30.48.20).

Do parking requirements vary by district?

Yes—parking requirements are tied to the site and building requirement tables and Article XXXI off‑street parking requirements. The district articles point to § 30.19.20 for commercial districts where the commercial site table flags where parking rules apply. Confirm specific stall counts and any downtown exemptions with the parking schedule and § 30.19.20. Link: Gilroy Parking.

If my parcel is in a special plan (Hecker Pass, Glen Loma) which rules control?

Special-use districts like Hecker Pass and Glen Loma Ranch defer to the corresponding specific plans for detailed land-use tables and site standards (e.g., Hecker Pass “Agricultural Use Table” Table 3‑2 and residential Table 3‑4). See § 30.29.20–30.29.30 and § 30.30.10–30.30.20.

Where do I check whether my proposed use triggers design review?

Many districts require architectural and site review for new construction or major alterations (for example downtown, hillside, and open space contexts). Check the district article for site review triggers and the city’s design-review rules; link: Gilroy Design Review. If in a historic combining district, additional findings in § 30.27.20 apply.
