San Benito County — Design Review

Design Review under the San Benito County local zoning and planning code, with the controlling citations.

Last reviewed: July 6, 2026

Overview

In unincorporated areas of San Benito County, “Design Review” is implemented through the County’s Development Plan Review process in Title 25 of the zoning code. It applies to most new construction and site changes, with streamlined exemptions and overlay-specific triggers in scenic corridors and hillside/ridgeline areas. This page explains when review is required, who approves it, what findings must be made, and how district-specific design standards apply across residential, commercial, industrial, and public sites.

The County uses two tiers of review for non-exempt projects: a staff-level Minor Development Plan Review by the Planning Director and a Major Development Plan Review by the Planning Commission; even otherwise-exempt projects must undergo review in designated scenic highway corridors and in hillside/ridgeline areas.

What triggers Design Review (Development Plan Review)

Design Review is codified as “Development Plan Review” with two pathways: Minor (Director) and Major (Planning Commission). Exempt items require only zoning clearance. Thresholds are summarized below.

Approving authorities:
- Minor Development Plan Review: Planning Director (may refer to Planning Commission; any written hearing request elevates the review to the Commission).
- Major Development Plan Review: Planning Commission.
Core thresholds (examples from Table 25.02-A):
- Single-family: A custom single-family home is typically Exempt (zoning clearance only); tract “master home plans” are Minor (≤10 homes) or Major (>10 homes).
- Multi-family: New development with 4 or fewer units is Minor; 5+ units is Major.
- Non-residential: New structures ≤3,000 sq ft are Minor; >5,000 sq ft are Major (2,501–5,000 sq ft additions are Minor).
- Agricultural/industrial accessory buildings: Up to 25,000 sq ft are Exempt; 25,001–50,000 sq ft are Minor; >50,000 sq ft are Major.

Overlay triggers that override exemptions

Scenic Highway Corridor: All new construction along designated segments (e.g., Hwy 101) requires Minor or Major Development Review, including projects otherwise “exempt.”
Hillside/Ridgeline: New residential structures/additions on slopes >15% or within mapped hillside viewsheds require Design Review by the Planning Commission with additional design criteria.

How review works (process, notice, hearings, findings)

Filing and fees: File on County forms; fees must be paid before processing; completeness review in 30 days.
Notice:
- Major reviews: public notice and a Planning Commission hearing.
- Minor reviews: mailed notice to adjacent owners/occupants; no hearing unless requested in writing (then heard by the Commission).
Required findings (all must be made):
- The proposal complies with applicable General Plan, zoning, any specific plan, and other regulations.
- The design respects terrain/drainage and infrastructure; is compatible with adjacent uses; and does not create circulation conflicts.
- Adequate utilities (sewer/septic, water, power) are available or will be provided.
- The project is not detrimental to public health, safety, welfare, nor to neighboring properties.
Conditions, modifications, appeals: Conditions may be imposed; minor changes post-approval can be processed by the Director; either the public or the applicant may appeal per Chapter 25.01.

Objective standards and required submittals commonly reviewed

The County applies objective, district-specific standards through Chapter 25.07 during Development Plan Review:

Residential architectural standards (apply when residential work in these zones requires review): R-1, PUD, RM, and C-2 must provide articulated street-facing facades, consistent rooflines, materials, and equipment screening.
Non-residential site/architectural standards: Commercial centers must present a unified architectural style, avoid long blank walls, orient entries to streets/parking, and screen parking; industrial projects must screen service areas/equipment and manage pedestrian/vehicular circulation.
Landscaping: A landscaping, grading, irrigation, and shading plan is required with development review; parking-lot shading minimums apply (e.g., 30–50% depending on lot size).
Outdoor lighting: Most new non-residential and multi-family lighting requires Minor Development Review and a lighting plan; accent/up-lighting is controlled.
Equipment/trash screening: Mechanical equipment and refuse enclosures must be screened and architecturally integrated.

Cross-check these with the County’s Development Standards and Landscaping and Screening pages.

District-by-District design lens (unincorporated areas)

Below are the districts most frequently implicated in Design Review, with their purpose, typical uses, and the design standards that tend to control. For district purposes and base development metrics, see Zoning and Land Use.

R-1 Single-Family Residential

Purpose/where used: Single-family neighborhoods; intensity set by utility availability.
Typical uses: Single-family dwellings (ADUs per state law).
Key dimensional standards: Front setback 20 ft, max height 30 ft (with additional lot-based side/rear formulas).
Design review angle: Custom single-family homes are usually Exempt (zoning clearance), but façade articulation, rooflines, materials, and equipment screening apply where a review is triggered (e.g., subdivisions, overlays).

RM Residential Multiple

Purpose/where used: Areas for multi-family dwellings at urban densities with services.
Typical uses: Apartments/condominiums; some single-family in limited cases.
Key dimensional standards: Max height 35 ft; front setback 20 ft; 8–20 du/ac (with infrastructure).
Design review angle: New multi-family of 5+ units requires Major review; ≤4 units is Minor. Objective standards address neighborhood compatibility, privacy, pedestrian circulation, and open space.

PUD Planned Unit Development (combining district)

Purpose/where used: Project-specific standards to better implement the General Plan; governing specific plan or PUD rules control.
Design review angle: When the specific plan/PUD is silent, Title 25 standards (including design review) apply; Board may impose conditions to ensure superior community design.

C-2 Neighborhood Commercial

Purpose/where used: Provide convenience shopping close to neighborhoods; mixed-use is allowed.
Typical uses: Neighborhood retail and services per use tables (all new structures reviewed).
Design review angle: Commercial design standards require unified style, human-scale massing, and screened parking; thresholds determine Minor vs. Major.

Industrial: BP Business Park, M-1 Light Industrial, M-2 Heavy Industrial

Purpose/where used: Employment/industrial districts with shared development metrics (e.g., max height 40 ft, FAR 0.8).
Design review angle: Industrial review emphasizes screening of loading and mechanicals, safe pedestrian/vehicle circulation, and landscape buffers (e.g., 10-foot landscaped strip, as determined during design review).

PQP Public/Quasi-Public

Purpose/where used: Government and civic facilities.
Design review angle: Several base standards in PQP are “Subject to design review,” meaning specifics are set through the review process (e.g., setbacks, FAR).

Overlay conditions that change review

Scenic Highway Corridor: Review is mandatory for all new construction and adds sign/landscaping/scar-screening constraints.
Hillside/Ridgeline: Commission-level design review applies, with criteria on siting, height, colors, and landscaping to protect viewsheds.

Checklist

Confirm zoning and any overlays; start at the County’s Zoning map/standards and Overlay Districts. Verify if the parcel lies in a scenic corridor or hillside/ridgeline area.
Determine your threshold (Exempt vs. Minor vs. Major) using Table 25.02-A; if exempt, obtain zoning clearance.
Prepare submittals required for development review: site plan, elevations, and any required landscaping/irrigation/shading plan; include outdoor lighting plan if applicable.
Design to applicable objective standards: residential façades/rooflines/materials; commercial/industrial massing, orientation, and screening; refuse enclosure standards.
File on prescribed forms, pay fees; track completeness and any public noticing steps (adjacent-mailer for Minor; full notice/hearing for Major).
Address the four required findings in your narrative (consistency, compatibility/circulation, utilities, no detriment).
If your design needs small adjustments to strict standards, consider a Minor Modification (e.g., up to 20% setback reduction, 10% height increase) rather than a variance.
Coordinate related approvals: Signage, Parking, and Landscaping and Screening often scope into Design Review. See County standards and avoid drifting into the California Building Standards Code (separate).

Risks & Ambiguities

Issue	Why it matters	What to verify
Scenic Corridor boundary	Even “exempt” work may need review inside the corridor	Confirm corridor width and location per § 25.08.027(B)–(F) before filing
Hillside/Ridgeline applicability	Triggers Commission-level design review and added criteria	Check slope >15% and viewshed criteria; Commission is the approving body per § 25.07.017(D)–(E)
Minor vs. Major threshold	Dictates review body, timeline, and noticing	Square footage/unit count thresholds in § 25.02.001, Table 25.02-A
Objective design standards	Missing an objective standard can block approval	Residential § 25.07.002; non-residential § 25.07.003; outdoor lighting § 25.07.012; landscaping § 25.07.011
Accessory structures	Some accessory/site features can shift a project from exempt to Minor	Use-table notes and accessory standards in §§ 25.07.006–25.07.008 cited in Table 25.02-A footnotes
Specific Plans/PUDs	Project-specific rules can supersede base standards	If a specific plan applies, it governs; Title 25 fills gaps (§ 25.06.001–.002)
Need for relief	Some designs need small deviations	Minor Modifications (§ 25.02.008) vs. Variances and Exceptions (§ 25.02.009)

Plain-English Summary

In unincorporated San Benito County, most small home projects are exempt from Design Review and just need zoning clearance, but new multi-family, larger commercial/industrial buildings, and anything in a scenic corridor or hillside/ridgeline go through Development Plan Review. Staff can approve smaller projects; the Planning Commission hears larger ones, and all approvals must meet clear, objective standards for architecture, siting, circulation, screening, landscaping, and lighting.

Frequently asked questions

Do I need design review for a custom single-family home in unincorporated San Benito County?

Usually no. A custom single-family home is typically Exempt and needs only a zoning clearance, unless you’re in a scenic highway corridor or hillside/ridgeline area (which mandate review). Check Table 25.02-A and overlay maps.

Who approves my design review—staff or the Planning Commission?

Minor Development Plan Reviews are approved by the Planning Director; Major Reviews are approved by the Planning Commission. Any written request for a hearing on a Minor Review elevates it to the Commission.

What findings must my project meet to pass design review?

All projects must show consistency with the General Plan/zoning, compatibility with surroundings and circulation, adequate utilities, and no detriment to health, safety, or neighboring properties.

I’m along Highway 101—does that change anything?

Yes. All new construction in a designated scenic highway corridor must complete Minor or Major Development Plan Review, even if the work would otherwise be exempt.

What extra standards apply to multi-family projects?

New 5+ unit projects require Major Review; ≤4 units require Minor Review. Objective standards govern compatibility, privacy (e.g., window offsets), pedestrian circulation, and open space.

Are landscaping and lighting reviewed too?

Yes. A landscaping/irrigation/shading plan is typically required with development review, and most non-residential/multi-family lighting installations need a lighting plan and Minor Review.

Can I get small relief from strict dimensional standards during review?

Possibly. The County may grant Minor Modifications (e.g., up to a 20% setback reduction or 10% height increase). Larger relief needs a variance.

What commercial design principles does the County expect?

Unified architectural style across a center, pedestrian-scaled massing, screened parking/loading, and entries oriented to streets or internal lots, with long blank walls avoided.
