San Juan Bautista — Design Review

Last reviewed: July 3, 2026

Overview

San Juan Bautista requires site plan and design review for most new construction, relocations, and major exterior work across residential, commercial, mixed‑use, institutional and public projects; the rules are in the Municipal Code's Site Plan and Design Review chapter. Design review is integrated with the City's historic‑resource review processes and certain overlay districts (for example, the hillside overlay and the designated historic districts) and can be either administrative or heard by the Planning Commission depending on the project type and zoning. See the City’s design review rules in the Zoning menu for where to start. § 11‑18‑010, § 11‑18‑020, § 11‑18‑030.

How San Juan Bautista’s design review works (quick legal grounding)

• Purpose and scope: The design review chapter sets intent to protect the City’s historic character, promote compatible architecture, and ensure safe, well‑landscaped site design. § 11‑18‑010.
• Applicability: Site plan and design review is required for historic resource projects and for “new construction, relocation and major exterior maintenance” of structures in most districts (residential, commercial, mixed‑use, industrial, institutional, public). § 11‑18‑020.
• Who decides: Large or specified projects are heard by the Planning Commission; limited single‑family R‑1 projects (under certain thresholds) may get administrative approval by the City Manager or designee. § 11‑18‑030(B)(1)‑(2).
• Required findings: Approvals require findings that the project complies with the Municipal Code standards, General Plan policies, protects heritage resources, is compatible with surroundings, addresses massing/landscaping, and that public facilities exist to serve the project. § 11‑18‑040(A)‑(I).

(Throughout this page, where the code delegates historic review, see the Historic Resources chapter for special rules and findings. § 11‑06‑120 and § 11‑06‑130.)

District‑by‑district implications for Design Review

Below are the districts and overlay areas most relevant to design review in San Juan Bautista, with the purpose, typical permitted uses (for design‑review context), and the key dimensional standards that often drive design decisions. Bolded district names and standards call your attention to the rules that most commonly affect design review decisions.

Note: verify parcel‑specific questions with the City Planner. Many dimensional numbers and exceptions appear in Chapter 11‑04 and the zoning table; follow the code citations below when preparing plans. Verify with the jurisdiction.

R‑1 (Single‑family residential — R‑1‑7, R‑1‑6, R‑1‑5)

• Purpose: Single‑unit neighborhoods; three sub‑designations reflect minimum lot sizes for single‑family housing. § 11‑04‑010(C).
• Typical permitted uses: Principal single‑family dwellings, accessory structures, accessory dwelling units (subject to ADU rules). § 11‑04‑010; ADU rules: 11‑04.5.
• Key dimensional/design considerations that affect review:
  • Subdistricts: R‑1‑7, R‑1‑6, R‑1‑5 as defined in § 11‑04‑010(C).
  • Maximum building coverage: 45% of lot (single‑family) and maximum site coverage 58%; front/side/rear yard requirements appear in the development standards table and Chapter 11‑04. § 11‑04‑010(A)‑(B).
  • Administrative vs. Commission review: small additions or non‑second‑story work under a 75% building‑area increase threshold may be administratively approved in R‑1; new homes, expansions ≥ 75%, or new second stories require Planning Commission review. § 11‑18‑030(B).

R‑2 / R‑3 (Multi‑family residential)

• Purpose: Allow duplexes and multifamily residential forms; R‑3 higher density. See Chapter 11‑04 for development standards. § 11‑04‑010.
• Typical permitted uses: Duplexes, small‑scale apartments, accessory uses consistent with multi‑family zoning; ADUs permitted subject to Chapter 11‑04.5.
• Key design triggers:
  • Density, height, FAR, setbacks and landscaping requirements in Chapter 11‑04 drive massing and parking expectations; ADU rules limit ADU size and placement (e.g., 800 sq ft maximum for many ADUs unless code allows larger). § 11‑04.5‑010 through 11‑04.5‑120.

MU (Mixed‑Use)

• Purpose: Mix of residential and commercial in appropriate locations; downtown core has special mixed‑use expectations. § 11‑04‑020 and development table notes.
• Typical permitted uses: Ground‑floor commercial with residences above; multifamily residential; limited institutional uses in mixed‑use pattern. § 11‑04.
• Key standards:
  • Floor area ratio guidance varies: in downtown historic district FAR may be 1.5, elsewhere MU FAR typically about 0.75 (subject to project‑specific increases through discretionary permits). (See the table notes in Chapter 11‑04.) Note9 and Chapter 11‑04.
  • ADUs are permitted in MU zones, subject to the Design Guidelines (see ADU chapter). § 11‑04.5‑110.

C (Commercial)

• Purpose: Retail, service, commercial activities serving the City. See Chapter 11‑04 table and notes.
• Typical permitted uses: Retail, restaurants, offices, visitor accommodations (subject to standards). § 11‑04; signage rules apply per Chapter 11‑10.
• Design triggers:
  • Setbacks in the C district are “consistent but not absolute” with adjacent residential setbacks; deviations allowed by Planning Commission on a case basis. (Table note 8.) Chapter 11‑04.
  • Sign programs and sign design are explicitly tied to the San Juan Bautista Design Guidelines and require Planning Commission approval for multi‑tenant sites. § 11‑10‑050 – 060.

I (Industrial)

• Purpose: Light industrial and industrial uses; development controls intended to limit nuisance impacts. See the table and Chapter 11‑04.
• Typical permitted uses: Manufacturing, storage, contractor yards (subject to screening and landscaping). § 11‑04.
• Design triggers:
  • Landscaping and screening rules (Chapter 11‑04, and parking Chapter 11‑11) are applied to buffer industrial uses next to residential zones. § 11‑04, § 11‑11‑070(C).

PF (Public Facilities) and P (Parks / Public)

• Purpose: Publicly owned buildings and parks; yard requirements reference the most restrictive adjacent district with minimums. Table notes and Chapter 11‑04.
• Design triggers: Yards, site access, and facility siting are reviewed to match adjacent character; design review ensures public facilities fit neighborhood character. Chapter 11‑04.

Hillside Overlay District (Hillside development)

• Purpose: Protect ridgelines, view sheds, slopes, and environmental constraints; special submittal requirements. § 11‑08‑020 – 040.
• Typical triggers for design review:
  • Projects on slopes ≥ 20%, or within ½‑mile view corridors and other specified areas, require hillside development review and specific plan materials (grading cross sections, landscaping, color palette, geotechnical reports). § 11‑08‑030; detailed submittal items listed at 11‑08.

Historic Districts and Historic Resources

• Purpose: Protect historically significant properties and districts and ensure compatibility with Secretary of the Interior Standards and the City's Historic Preservation Design Guidelines. § 11‑06 (Historic Resources Board duties and design review for historic resources).
• Typical process:
  • Projects on properties > 45 years old, properties on the local register, or within designated historic districts are routed through the Historic Resources Board (HRB) for review and recommendation, and may require additional historic resource reports or DPR forms. § 11‑06‑120(A)–(C).
  • Approval findings for historic resource projects add the requirement that work be consistent with the Secretary of the Interior Standards and the City’s preservation guidelines. § 11‑06‑130.

Quick reference table — decision‑relevant design standards and where they live

How design review documents must look (materials & submittal)

The code requires a complete application to include plans, elevations, material samples and other documentation sufficient to fully describe the project; for hillside or historic projects, additional technical studies (geotechnical, historic reports, DPR forms) are expressly required. The Planning Commission/City Planner will not schedule an application until the submittal is complete. § 11‑18‑030(A); hillside submittals listed at 11‑08; historic report requirements at 11‑06.

Practical points:

• Provide color palettes, material samples, scaled elevations, landscape plan and a narrative describing how the project meets the findings in § 11‑18‑040.
• If the parcel is historic or > 45 years old, expect the HRB to request a historic resource evaluation (DPR 523 forms) and apply Secretary of the Interior Standards. § 11‑06‑120 and § 11‑06‑130.

Checklist (what an applicant must satisfy before or with a complete design review submittal)

• Confirm whether the property is subject to the Historic Resources chapter (is it > 45 years old, on the Register, or inside a designated historic district?). § 11‑06‑120(B).
• Provide full set of plans (site plan, elevations, materials, colors) and a project narrative tied to the findings in § 11‑18‑040. § 11‑18‑030(A); § 11‑18‑040.
• If in a hillside overlay, include grading cross‑sections, geotechnical report, landscape mitigation and view‑shed analysis. § 11‑08‑030.
• If a historic property, submit DPR forms and a historic resource evaluation by a qualified professional; follow Historic Preservation guidelines. § 11‑06‑120; § 11‑06‑130.
• Address parking, access and landscaping standards, including aisle widths, tree planting and permeable surfaces as required by Chapters 11‑11 and 11‑04. § 11‑11‑060, § 11‑04‑090.
• Identify which review route applies (administrative City Manager hearing vs Planning Commission public hearing); prepare for public notice if Planning Commission review is required. § 11‑18‑030(B); public noticing per Government Code (300' notice).

(For accessory dwelling units see the specific ADU rules and ministerial pathways in Chapter 11‑04.5.)

Risks & Ambiguities

Plain‑English summary

If your project is new construction, a big exterior change, within the hillside overlay, or on an older/historic property in San Juan Bautista, you will almost certainly need to go through the city's site plan and design review process (either administratively or at a public Planning Commission hearing). The City looks at compatibility with neighborhood character, historic resources, landscaping, parking and public services, and requires specific plans and sometimes technical reports to make findings before approval. § 11‑18‑020, § 11‑18‑040.
