San Juan Bautista — Nonconforming Uses

Last reviewed: July 3, 2026

Overview

San Juan Bautista treats nonconforming uses, structures and lots as legally existing conditions that are tolerated but not encouraged to continue indefinitely. The zoning ordinance (Title 11 of the San Juan Bautista Municipal Code) sets the rules for continued operation, repairs, change, expansion, damage/restoration, and loss by abandonment — primarily in § 11-15-010 through § 11-15-090.

The rest of this page summarizes what the code actually says, how special rules (historic and ADU chapters) interact with nonconforming items, and what an applicant must check before proposing work or a change of use.

Note: this page stays strictly within the San Juan Bautista zoning/planning ordinance text retrieved and cites the controlling local code sections. Where the ordinance text in the materials did not provide full detail, I mark that as "Not found in retrieved materials" below.

(Links: the city's rules on setbacks and development standards are summarized in the San Juan Bautista Development Standards page; the code’s ADU chapter affects some nonconforming-dwelling issues—see San Juan Bautista ADUs; if your proposal affects site layout or off-street parking consult the San Juan Bautista Parking rules; design and historic reviews live under San Juan Bautista Design Review and San Juan Bautista Historic Preservation. Also verify any structural or life-safety work against the California Building Standards Code.)

What San Juan Bautista’s ordinance requires (core rules)

• Intent: Existing legal uses/structures that no longer conform are declared nonconforming and should not be encouraged to continue permanently (the City calls these “nonconforming” by intent). § 11-15-010.
• Continuation: A lawful existing nonconforming use, building or structure may be continued unless other restrictions apply (except for those established unlawfully prior to the ordinance). § 11-15-020.
• Change to conditional use: A use that used to be permitted but is reclassified as conditional remains nonconforming until a conditional use permit is obtained. § 11-15-030.
• Repairs and maintenance: Ordinary, nonstructural repairs are allowed without special permit; structural repairs or alterations to nonconforming buildings are generally prohibited except when required by law or authorized by the Planning Commission via a conditional use permit — with an explicit residential exception allowing structural repairs for residential buildings used as allowed in the zone. § 11-15-040.
• Cessation/abandonment triggers loss of status:
  • If a nonconforming use in a building stops for one (1) continuous year, the building cannot again be used for a nonconforming use. § 11-15-060(A).
  • If a nonconforming use of land (no building) ceases for six (6) continuous months, it cannot be resumed as nonconforming (minor appurtenances under 400 sq.ft. are excluded). § 11-15-060(B).
• Damage and restoration:
  • Except for multifamily dwellings, if ≤ 75% of the building's value (above foundation) is destroyed by calamity it may be reconstructed if rebuilding begins within 6 months and is completed within 1 year; if > 75% damaged, the rebuilt structure must conform to current zoning. § 11-15-070.
  • Multifamily dwellings have special reconstruction allowances per state law, but the City can deny reconstruction where the repair would be injurious or there is no appropriate zone for the use. § 11-15-080 (references Govt. Code § 65852.25).
• Expansion/changes:
  • A nonconforming use may be expanded only after obtaining a conditional use permit (Chapter 11-20). § 11-15-090(A).
  • A nonconforming building or structure may not be expanded unless the added area complies with all current zoning requirements, and the City Manager may refer additions that affect parking to the Planning Commission and attach conditions. § 11-15-090(B).

Table — most decision-relevant nonconforming rules (quick reference)

District-by-district notes (what the ordinance materials say about nonconforming items, by district)

Below are San Juan Bautista district headings actually used in the code. For each district I summarize what the retrieved ordinance materials say about nonconforming-related treatment, plus tangible dimensional notes found in the retrieved materials. Where the ordinance text did not include a full permitted-uses list or a complete numeric table in the retrieved snippets I mark that as "Not found in retrieved materials" and point you to the code sections to verify.

Important: the code contains a zoning standards table (setbacks, lot sizes, FAR, etc.) referenced by notes in the materials; the full table rows were not captured verbatim in the retrieved snippets. Verify parcel-specific numbers with the Planning Department. Notes below cite the pieces of the code that were retrieved.

R-1 (Single-family residential)

• Purpose / typical uses: Single-family residential (the ADU chapter explicitly lists R-1 as a permitted zone for ADUs and JADUs and calls out “single-unit residential zones”). § 11-04.5-020 and § 11-04.5-150(J–K).
• Nonconforming specifics: Nonconforming residential buildings are allowed ordinary and, in limited cases, structural repairs where the building continues to be used for residential uses in a zone that allows residences. § 11-15-040(A).
• Dimensional standards / where applied: The code notes the Planning Commission may grant R-1-6 or R-1-5 designations within R-1 under criteria in § 11-04-010 (note referencing local table). For specific setbacks, lot sizes and density, see the zoning standards table and notes (not fully present in retrieved snippets). Not found in retrieved materials (table).

R-2 (Multifamily / medium density)

• Purpose / typical uses: Multifamily residential uses are contemplated; the ADU rules include R-2 in the list of zones where accessory dwelling units are allowed. § 11-04.5-020.
• Nonconforming specifics: Multifamily dwellings enjoy the special restoration rule referencing Government Code § 65852.25 (City must follow that state standard and may decline rebuild only under narrow findings). § 11-15-080.
• Dimensional standards / where applied: The municipal notes refer to guest houses on lots less than the minimum size for R-1 and R-2 as an historic-incentive exception (historic resources chapter). For specific numerical standards, see local zoning table (not fully captured). Not found in retrieved materials.

R-3 (Higher-density residential)

• Purpose / typical uses: Higher-density residential (the ADU chapter mentions R-3 as an allowable zone for ADUs). § 11-04.5-020.
• Nonconforming specifics: Same general nonconforming provisions apply; multifamily-specific restoration rules in § 11-15-080 may be relevant.
• Dimensional standards / where applied: Not fully captured in retrieved snippets (verify with the zoning table). Not found in retrieved materials.

MU (Mixed-Use / downtown)

• Purpose / typical uses: Mixed-use, includes both commercial and residential uses; the code explicitly references MU in the definition of “historic resource” and ADU applicability, and FAR allowances differ in MU/downtown. § 11-04.5-020; zoning table notes.
• Nonconforming specifics: Historic-area exceptions (Chapter 11-06) allow maintaining legal nonconforming front/side/rear setbacks and limited additions without forcing conformance; that directly applies to MU/downtown historic structures. § 11-06-130(B)(3).
• Dimensional standards: For building in the downtown historic district the code notes the floor area ratio (FAR) "may be 1.5"; in other MU areas FAR is listed as 0.75 — with potential adjustment by use or conditional use permit. (Zoning notes). Not a full table — verify with Planning.

C (Commercial district — identified as “C district”)

• Purpose / typical uses: Commercial uses; the code treats setbacks for the C district as “consistent but not absolute” with adjacent residential districts and allows deviations by the Planning Commission. (See table notes.) Not found: full permitted-use list in retrieved snippets.
• Nonconforming specifics: Historic preservation exceptions can allow establishment of historic uses in underlying C zoning (Chapter 11-06 incentives) and allow nonconforming setbacks to be retained in additions with approval. § 11-06-130(B).
• Dimensional standards: Setback deviations possible by Planning Commission; see zoning table for numeric standards. Not found in retrieved materials.

PF (Public Facilities), A (Agricultural), I (Industrial) — brief notes

• The code’s notes reference PF yard rules tying minimum yards to the most restrictive abutting district and specific minimums (note 11 in the zoning notes). § (zoning table notes).
• Industrial (I) and Agricultural (A) districts are referenced in other operational standards (e.g., fences, storage) and the wireless communications section includes rules for siting near residential zones; nonconforming wireless facilities are allowed to continue but cannot be enlarged to increase nonconformity. § 11-04-110 and wireless provisions.

How overlays and other chapters change the nonconforming picture

• Historic Overlay: The Historic Resources chapter provides explicit incentives and exceptions that let qualifying historic properties preserve and continue historic uses and legal nonconforming conditions (including retaining nonconforming setbacks and limited additions) upon approval of use permits and design/site plan review — see § 11-06-130(B). This is the single largest local modifier of nonconforming rules for downtown and designated historic properties.
• Hillside Overlay: The Hillside Development Regulations (Chapter 11-08) overlay require special permitting and design review; nonconforming hillside development will be subject to those discretionary findings and conditions. § 11-08-030 (applicability) and § 11-08-070–080.
• Lighting: The outdoor lighting chapter explicitly requires that when a nonconforming use/structure/lot abandoned for 1 year is re-commenced, lighting must be reviewed and brought into conformance where practicable. § 11-13-020(B).
• ADUs and nonconforming conditions: The ADU chapter states that correcting a physical nonconforming condition is not required to establish an ADU; former secondary dwellings that do not meet current standards are to be classified as nonconforming buildings and uses. § 11-04.5-150(G) and § 11-04.5-020.

Checklist (what an applicant must verify / provide for nonconforming-related proposals)

• Confirm the use/structure was lawfully established before the current ordinance (document chain of title, permits) — required to claim nonconforming status (§ 11-15-020).
• Confirm whether the use stopped and when (determine if the 6‑month or 1‑year abandonment clock has run) — § 11-15-060(A–B).
• For repairs: identify whether proposed work is structural or nonstructural (structural repairs to nonconforming buildings generally need Planning Commission authorization/conditional use permit) — § 11-15-040.
• For expansion of use or building: prepare a conditional use permit application if expanding a nonconforming use, or show added area complies with current zoning for building expansions (§ 11-15-090(A–B)).
• If work is in a historic overlay: prepare Design Review and Historic Resources Board materials (Secretary of Interior Standards, site plans) and check historic incentives/exceptions in § 11-06-130.
• If restoring after damage: calculate percent of value lost (per County Assessor) and prepare required timeline documentation (start within 6 months and complete within 1 year if ≤75% damage) — § 11-15-070.
• Check parking and site impacts — additions to nonconforming structures that increase parking demand may be referred and conditioned (see § 11-15-090(B) and consult the city's San Juan Bautista Parking standards).
• If proposing an ADU/JADU: identify whether the property has nonconforming zoning conditions — the ADU chapter explains when corrections are required or not (§ 11-04.5-150(G)).

Risks & Ambiguities

Plain-English Summary

If your building or use was legal when the current zoning rules took effect, San Juan Bautista will typically let it keep operating, but you generally cannot expand it unless you get a conditional use permit; repairs that are nonstructural are allowed, and if the use stops (6 months for land-only uses, 1 year for building uses) you lose the right to go back to that nonconforming use. Restore after damage only under the timetable and percent-damage rules in the code, and check the historic-overlay rules because historic buildings have special exceptions. See § 11-15-010 through § 11-15-090, plus the Historic Resources and ADU chapters for important exceptions.
