Overview

This page summarizes what the San Jacinto Development Code (Title 17) actually requires for development standards — setbacks, heights, lot coverage, density, and FAR — and how those rules differ by zone. It is drawn directly from the City's Development Code tables and controlling sections; where the code delegates measurement, exceptions, or review the controlling § is cited. Read this as an ordinance-focused reference (not building-code / Title 24 guidance). See the City’s zoning menu for related topics like parking and design review.

  • Title of the code used: Title 17 — Development Code (§ 17.100.010) .

How to read this page

Quick legal anchors (what controls measurement and exceptions)

  • Setback measurement and exceptions: § 17.305.120 (Setback Regulations and Exceptions) .
  • Lot / parcel rules: § 17.305.030 (Lots) .
  • Residential zone tables and density incentives: Chapter 17.215 (Residential Zones), specifically § 17.215.035 (Paving within front yard) and § 17.215.040 (Residential density incentives) — see Table 2‑4 for numeric standards .
  • Mixed‑use, commercial, and industrial numeric standards appear in Article 2 tables (Tables 2‑6, 2‑7, 2‑8, 2‑9) and are enforced per Article 3 measurement rules; see § 17.305.060 (Height measurement) and § 17.305.120 for setbacks .
  • ADU-specific constraints that interact with lot coverage/setbacks/FAR are in the ADU provisions referenced in the Development Code; see ADU-specific subsection material (ADU rules summarized below) .
  • Deviations and increases (variances, minor variances, planned development adjustments) are handled by Chapter 17.650 (Variances) and Chapter 17.620 (Planned Development) — these allow limited percent adjustments for FAR, coverage, setbacks, heights, etc., subject to findings (see Table 6‑3 for minor variance limits) .

District-by-district breakdown (purpose, typical uses, key dimensional standards, where it applies)

Note: the numeric standards below are drawn from the Development Code tables (Article 2). When the tables refer to measurement rules, use § 17.305.120; when projects qualify for site plan/design review or density incentives, see § 17.630 and § 17.215.040 respectively. Table citations are shown where the numeric values come from.

RL — Residential, Low‑Density

  • Purpose / typical uses: Single‑family detached homes and detached ADUs; basic neighborhood residential. (See Chapter 17.215 for zone intent.)
  • Key dimensional standards (from Table 2‑4): Minimum density 2.1 du/acre; Maximum density 7.0 du/acre; Front setback 20 ft; Interior side 5 ft; Street side 10 ft; Rear 20 ft; Lot coverage 55%. Measurement and exceptions per § 17.305.120.
  • Where it applies: Standard detached neighborhoods; ADUs are allowed but must follow ADU-specific limits in the Code (see ADU subsection) and the accessory standards in Chapter 17.405.

RM — Residential, Medium‑Density

  • Purpose / typical uses: Townhouses, small multifamily (duplexes, triplexes), apartments in lower‑rise form.
  • Key dimensional standards (Table 2‑4): Minimum density 5.0 du/acre; Maximum density 14.0 du/acre; Front setback 15 ft (house) / 20 ft (garage); Interior side 5 ft; Street side 7 ft; Rear 10 ft; Lot coverage 60%. See multi‑family standards in Chapter 17.420 for additional spacing/amenity requirements.

RH — Residential, High‑Density

  • Purpose / typical uses: Mid‑rise multifamily, apartments and stacked flats.
  • Key dimensional standards (Table 2‑4 & Chapter 17.420): Minimum density 14.1 du/acre; Maximum density 22.0 du/acre; multi‑family setbacks and yard rules are referenced to Chapter 17.420 (so front/setback entries are handled in that chapter) and lot coverage 60%. (See Table 2‑4 and Chapter 17.420.)

RVH — Residential, Very High‑Density

  • Purpose / typical uses: Higher intensity multi‑family/mixed residential (urban multifamily, podium or mid‑rise within the City’s high-density band).
  • Key dimensional standards (Table 2‑4): Minimum density 22.1 du/acre; Maximum density 32.0 du/acre; Lot coverage 60% (multi‑family rules apply); setbacks and other specifics are handled in Chapter 17.420 and Article 3 measurement sections.

MU / MU‑E / DV — Mixed‑Use (and Mixed‑Use Entertainment / Downtown Village)

  • Purpose / typical uses: Horizontal/vertical mixed use; retail and commercial at street level with residential above; more compact urban development. See mixed‑use development rules in the MU/MU‑E/DV table.
  • Key dimensional standards (Table 2‑8): Minimum density 10.1 du/acre, Maximum density MU/MU‑E 36.0 du/acre, DV up to 40.0 du/acre; Maximum FAR 0.75 (MU) / 1.0 (MU‑E) / 2.0 (DV); Structure coverage up to 80% (MU/MU‑E) and 100% (DV); perimeter setbacks vary (abutting residential 15 ft, abutting nonresidential 10 ft, abutting street 0–15 ft depending on subzone); height steps tied to distance from perimeter property lines (35–45 ft per Table 2‑8). Use § 17.305.060 for height measurement and § 17.305.120 for setbacks.

Commercial / Office (CN, CG, CR, OP)

  • Purpose / typical uses: Neighborhood commercial (CN), general commercial (CG), regional/commercial retail (CR), and office professional (OP).
  • Key dimensional standards (Table 2‑6): Maximum FAR 0.40 (CN) / 0.50 (CG, CR, OP); Front setbacks 10–15 ft depending on district; where abutting residential, side/rear setbacks jump to 10–35 ft; Primary structure height typically 35–45 ft depending on district; impervious coverage varies (70–90%). See Table 2‑6 for full matrix and § 17.305.120 for measurement.

Industrial (BP, IL, IH)

  • Purpose / typical uses: Business park (BP), light industrial (IL), heavy industrial (IH).
  • Key dimensional standards (Table 2‑7): FAR 1.0 (BP) / 0.50 (IL & IH); setbacks larger where abutting residential (25–75 ft depending on zone and side); Primary structure height 45 ft (BP/IL) / 60 ft (IH); impervious coverage high (70–85%). See Table 2‑7 and § 17.305.120 for measurement and exceptions.

Small‑lot residential in Mixed‑Use zones (Table 2‑9)

  • When a small‑lot subdivision is used within MU or MU‑E, different parcel minimums and setbacks apply: e.g., Parcel area 3,000 sq ft, Front 15 ft (house), 20 ft (garage), Interior side 5 ft, Rear 5 ft, Primary structure height 45 ft. See Table 2‑9 for full list.

How measurements and exceptions work (practical guidance)

  • Setback measurement, projections, and ambiguous lot line situations are controlled by § 17.305.120; always confirm the applicable measurement rule before applying a numeric setback. The Development Code repeatedly points readers to § 17.305.120 where the tables present numeric minimums (tables themselves reference the measurement rules) .
  • Lot coverage and FAR in the zone tables are maximums unless you receive a formal adjustment. Minor variances can increase FAR or coverage by limited percentages (see Table 6‑3/Chapter 17.650 — minor variance caps: FAR +10%, coverage +10%, setbacks -15% etc.) .
  • Planned development permits (Chapter 17.620) can modify many development standards (coverage, FAR, height, setbacks) but not increase density/intensity beyond the maximum allowed in Article 2 unless processed under density‑bonus law (Gov. Code § 65915) and the City’s density bonus chapter 17.310 .
  • Accessory structures and ADUs: accessory building heights and setbacks are controlled by Chapter 17.405 and Table 4‑1; detached accessory structures are limited to 15 ft height in most cases; ADU rules include 4‑ft side/rear setbacks and zone‑specific lot coverage caps for ADUs (e.g., 50% RL/RR, 60% RM/RH/RVH) — see the ADU subsection and the local ADU provisions for the code cross‑references (ADU provisions appear in the Development Code text) .

Minor variances FAR increase ≤ 10%, coverage increase ≤ 10%, setback reductions ≤ 15% (Table 6‑3) Chapter 17.650, Table 6‑3

Practical synthesis & guidance

  • If you’re designing a typical single‑family home in the RL zone: target 20 ft front, 5 ft side, 20 ft rear and confirm lot coverage ≤ 55%; verify driveway/paving limits via § 17.215.035 (driveway paving caps) before finalizing hardscape plans .
  • For multifamily projects, plan to demonstrate conformance with Chapter 17.420 (multi‑family) and the RVH/RH/RM density ranges in Table 2‑4; amenity‑based density incentives are available if you provide qualifying amenities (see Table 2‑5 and § 17.215.040) .
  • If your project needs to push FAR/coverage/height beyond the table, check whether a minor variance (Director) or variance (Commission) is appropriate (Chapter 17.650, Table 6‑3 caps), or whether a planned development permit (Chapter 17.620) can be used to adjust standards for larger projects — but density increases above the table require use of the City’s density‑bonus chapter 17.310 and compliance with state density‑bonus law .
  • Always confirm how your yard lines and driveway orientation interact with the measurement rules in § 17.305.120 because many table dimensions are “minimum” but measurement and allowed projections are in that section .

Checklist

  • Confirm the base zone for the parcel and pull the correct table (Table 2‑4 / 2‑6 / 2‑7 / 2‑8 / 2‑9) for numeric limits (setbacks, height, coverage, density/FAR). See Article 2 tables.
  • Verify setback measurement and allowable projections per § 17.305.120.
  • Check ADU rules (side/rear 4 ft exceptions, ADU lot coverage caps) and state ADU law implications. See ADU subsection in the Code.
  • Confirm lot coverage and driveway/hardscape limits per § 17.215.035 (paving limits).
  • If seeking departures (FAR/coverage/setback/height), confirm minor variance caps in Chapter 17.650 (Table 6‑3) or planned development options under Chapter 17.620.
  • Allocate required parking per San Jacinto Parking (Off‑street parking Chapter 17.330 referenced throughout the tables).
  • Determine whether site plan & design review is triggered and which authority reviews it (see § 17.630 and Table 6‑2). See San Jacinto Design Review.

Risks & Ambiguities

Issue Why it matters What to verify
Which table applies to a specific parcel (residential vs. mixed‑use overlays) Mixed‑use and overlay exceptions can change setbacks, coverage, and FAR materially. Confirm zoning designation on the parcel and whether overlays apply; consult Table 2‑8/2‑9 and Overlay rules. Verify with Planning staff.
Setback measurement (lot irregularities / corner/reversed corner) A small change in where the building line is measured can flip whether you comply. Review § 17.305.120 for measurement rules and Director interpretations; obtain a zoning clearance if lines are unclear.
ADU size vs. lot coverage / FAR interactions ADU size caps and ADU lot coverage caps can be more restrictive than the zone table, limiting as‑built ADUs. Pull the ADU subsection and cross‑check ADU lot coverage caps against Table 2‑4; confirm exceptions in the ADU provision.
Whether a project qualifies for density incentives (Table 2‑5) Qualifying for incentives changes allowed density and may permit otherwise unavailable units. Confirm eligibility for amenity categories in Table 2‑5 and whether site plan & design review approval is required.
Minor variance vs. full variance vs. planned development Each route has different submittal, findings, time and cost; some increases (density) can’t be granted by PD. Check the caps in Table 6‑3 and the limits of Chapter 17.620; density increases above zone max require conformance with Chapter 17.310 (density bonus) and state law.

Plain‑English summary (homeowner)

San Jacinto’s zoning tables (Article 2) set the numeric yardsticks you must meet: front, side and rear setbacks, maximum lot coverage, height limits and density ranges for each zone. For single‑family RL lots expect ~20‑ft front yards and ~5‑ft side yards and coverage around 55%; multifamily and mixed‑use have higher coverage and FAR. Measurement rules, ADU-specific exceptions, and small adjustments (minor variances or planned development) are controlled elsewhere in Title 17 — always confirm the parcel’s base zone, applicable overlay, and measurement rules before final plans. See § 17.305.120, Chapter 17.215, and the zone tables for the concrete numbers.

Frequently asked questions

What can I build on an R‑1 / RL lot in San Jacinto?

On an RL lot the code expects single‑family detached homes as the typical use; numeric development standards from Table 2‑4 apply (front setback 20 ft, interior side 5 ft, rear 20 ft, lot coverage 55% and density 2.1–7 du/acre). Verify project‑specific measurement rules in § 17.305.120 and accessory/ADU rules in Chapter 17.405 and the ADU subsection.

What are San Jacinto setback requirements?

Setbacks are listed by zone in the Article 2 development tables (for example, RL front 20 ft, side 5 ft, rear 20 ft in Table 2‑4). The measurement of those setbacks, allowed projections, and exceptions are controlled by § 17.305.120, so always confirm measurement rules for corner/reversed corner lots.

What are the height limits in the mixed‑use and commercial zones?

Mixed‑use districts set height limits that step with distance from perimeter lines (building sections within 10 ft of perimeter 35 ft; 10–20 ft = 40 ft; 20–30 ft = 45 ft) in Table 2‑8. Commercial zones generally list primary structure heights of 35–45 ft depending on the district (Table 2‑6). Height measurement rules are in § 17.305.060.

How does FAR work in San Jacinto?

FAR maximums are listed in the Article 2 tables: for example MU max FAR 0.75, MU‑E 1.0, DV 2.0 (Table 2‑8); commercial FARs are 0.40–0.50 (Table 2‑6); industrial FARs are listed in Table 2‑7. FAR is measured per the definitions in Article 8 and is subject to the measurement rules referenced in the tables (see § 17.305.060 / § 17.305.120).

Can I exceed the table limits for coverage / FAR / setbacks?

Limited increases or reductions can be obtained via minor variance (Director) for small percentage adjustments (see Table 6‑3: FAR +10%, coverage +10%, setbacks -15% caps) or a full variance (Commission) with findings; larger or project‑wide adjustments usually require a planned development permit (Chapter 17.620). Density increases above zone maximums require compliance with Chapter 17.310 and state density‑bonus law (Gov. Code § 65915).

What special rules apply to ADUs regarding setbacks and lot coverage?

ADU provisions in the Development Code require 4‑ft side and rear setbacks for many ADUs, and control ADU lot coverage so the ADU does not push the parcel beyond local lot coverage caps (examples in the Code: RL/RR 50%, RM/RH/RVH 60%, MU 75% for ADU calculation). ADU rules also reference state ADU law and limit local rules that would prevent an 800 sq ft ADU under state constraints. Always cross‑check the local ADU subsection with Table 2‑4 coverage values.

Do I need design review for changes that increase height or FAR?

Yes — the site plan & design review rules require design review prior to building/grading permits for specified changes (see § 17.630 and Table 6‑2 for thresholds). Projects that increase building height or exceed certain size thresholds will trigger Commission review or Director decision depending on scale.

Where are parking requirements handled and how will they affect my coverage/FAR calculations?

Parking is handled in Chapter 17.330 (Off‑Street Parking and Loading Standards); the zone development tables repeatedly refer projects to that chapter. Parking layout can affect usable site area and impervious coverage, so factor San Jacinto Parking standards into lot coverage and open space calculations early.

What if my lot is irregular or on a cul‑de‑sac — how are widths/depths measured?

Title 17 defines lot width/lot depth measurement rules and includes cul‑de‑sac exceptions to minimum dimensions; see § 17.305.030 (Lots) and the measurement rules referenced in the zone tables. If lines are ambiguous the Director establishes required setbacks under § 17.305.120.

Is there flexibility for large master‑planned or phased projects?

Large projects (100+ acres or 500+ units) must file a Planned Development permit or a Specific Plan (Chapter 17.620 / 17.635). Planned Development permits can modify many development standards (setbacks, FAR, coverage, height) but cannot raise density beyond allowable maxima without following density‑bonus/transfer rules. ---
