Duarte — Signage

Last reviewed: July 2, 2026

Overview

Duarte regulates signs in Chapter 19.42 of the Development Code (Title 19). The Chapter sets permit triggers, exemptions, per-zone sign tables, design/illumination rules, comprehensive sign program requirements, and enforcement/removal rules. Read this page together with Duarte's zoning maps and development rules for setbacks and parking because sign allowances are keyed to zone, frontage length, and parking/parcel layout. (§ 19.42.010; § 19.42.110)

(Links: first mention of related topics below — see parking, development standards, design review, overlays, ADUs, and the State building code.)

• For how sign rules interact with site layout and count of lineal frontage, check Duarte Development Standards. Duarte Development Standards
• For parking allocations that must be submitted with many sign proposals, see Duarte's parking rules. Duarte Parking
• Sign permit review is tied into Duarte's site plan / design review process; see Duarte Design Review. Duarte Design Review
• If your parcel sits in an overlay, special sign rules may apply. Duarte Overlay Districts
• Condo conversions and ADU projects have special allocation/authorization rules that affect sign permits. Duarte ADUs
• Structural, electrical and fire safety rules for installed signs remain subject to the California building code. California Building Standards Code

Controlling ordinance & procedural highlights

• Purpose and scope: sign regulation implements General Plan design and safety objectives, protects pedestrian/vehicular safety, and preserves aesthetics while respecting free-speech limits. See § 19.42.010.
• Permit required: a sign permit is required for all signs governed by Chapter 19.42; permits follow processing procedures in the Development Code and site/design review when applicable. See § 19.42.040 and § 19.42.060.
• Exemptions: a list of exempt sign types (civic, certain construction signs, directional, directory, display board signs, flags, governmental signs) is provided — exemptions still must meet other codes (e.g., Title 16/Building). See § 19.42.070.
• Illumination and prohibited signs: illumination is limited (internal allowed; external only with Director authorization) and billboards are prohibited. See § 19.42.260 and § 19.42.270.

District-by-district sign summary

Below are the Duarte zones that Chapter 19.42 addresses explicitly. For each zone I give the purpose of that zone (from Table 1-1 / Article 2), the sign types commonly used there, and the decision‑relevant dimensional standards from the sign tables.

Notes on reading the tables: the Code calculates allowable area either as a fixed maximum per sign type or by the common formula "1 sq. ft. of sign area per 1 lineal foot of primary building frontage" unless otherwise noted; measurement rules and height measurement are in § 19.42.110.

Residential zones — R-1, R-1A, R-1B, R-1D, R-1E, R-1F, R-2, R-3, R-4

• Purpose / where it applies: single- and multi-family neighborhoods (see Table 1-1 and residential zone descriptions).
• Typical sign types: building address, small identification for residential complexes, real estate and temporary developer signs, yard sale signs. See § 19.42.120 and Table 3-15.
• Key dimensional standards (decision-relevant): building address signs capped at 4 sf; residential complex identification signs 15 sf max and wall signs cannot extend past the roofline; temporary on-site new development signs 64 sf and 8 ft high (per-entry allowance); real estate signs 6 sf and 6 ft height. See § 19.42.120.
• Practical guidance: If your property is a multi-tenant residential complex, expect a single identification sign allowance tied to each street frontage and landscaping requirements for monument signs. See § 19.42.120(B).

Commercial — C-G (Commercial General)

• Purpose / where it applies: neighborhood/general commercial frontage (Table 1-1).
• Typical sign types: wall signs, hanging/projecting signs, monument signs, A-frame, directional, tenant identification. See § 19.42.130 and Table 3-16.
• Key dimensional standards: A‑frame signs typically 4½ ft high and 12 sf per side; monument signs vary by development size (example: 1.5 acres or less — 6 ft high; larger sites allow taller monuments up to 15 ft where noted); wall sign allowances are generally computed as 1 sf per lineal foot of frontage unless otherwise capped in the table. See § 19.42.130 and Table 3‑16.
• Practical guidance: corner parcels adjacent to major or secondary streets can receive additional monument sign allowances; verify frontage thresholds (acreage) to determine monument height/number. See § 19.42.130.

Commercial — C-F (Commercial Freeway)

• Purpose / where it applies: parcels oriented to the I-210 freeway or major corridor where visibility to freeway traffic is a design objective.
• Typical sign types: freeway-oriented signs, larger monument signs and, in limited cases, high-rise identification (with ARB approval). See § 19.42.140 and related high-rise provisions § 19.42.170.
• Key dimensional standards (highlights): freeway signs — up to 80 ft height as allowed in the table (may be higher with ARB approval) and 200 sf maximum sign area typical for freeway sign structures; monument sign siting must be between 10 ft and 500 ft from freeway centerline (location limits). See § 19.42.140.
• Practical guidance: freeway sign proposals require detailed ARB/comprehensive sign program review and special attention to sight-distance and illumination conditions. See § 19.42.140 and § 19.42.190.

Commercial — C-P (Commercial Professional) and H (Hospital)

• Purpose / where it applies: professional office and administrative uses (C-P); hospital district (H). See Table 1-1.
• Typical sign types: wall signs, tenant identification, monument signs, directional signs; hospitals may have special allowances (e.g., roof signs on very tall hospital buildings). See § 19.42.150 and Table 3-18.
• Key dimensional standards: monument signs typically capped at 6 ft / 32 sf in these zones; mansard/parapet/wall signs use the frontage formula with specific maximums (single-story up to 90 sf in many cases; multi‑story allowances escalate with floors, subject to caps). Roof signs allowed in H only for buildings over 5 stories (up to 10 ft above parapet; 120 sf cap). See § 19.42.150.

Industrial — M (Light Manufacturing)

• Purpose / where it applies: light manufacturing/industrial areas. See Table 1-1.
• Typical sign types: wall/tenant signs, monument signs, directional signs. See § 19.42.160 and Table 3-19.
• Key dimensional standards: monument signs commonly allowed at 8 ft tall and 40 sf (1 sign per development) in M zone; mansard/parapet/wall signs use the frontage formula up to 120 sf in many cases; hanging/projecting signs limited to 6 sf. See § 19.42.160.

Institutional — I (note)

• Institutional signage standards expressly reference the commercial/professional/hospital sign standards — see § 19.24.060, which directs that institutional signage reference § 19.42.150 (C‑P and H zone standards) unless otherwise provided. Verify applicable Specific Plan language for institutional campuses (e.g., City of Hope Specific Plan).

Key decision-relevant table (quick reference)

(Always consult the zone-specific table in Chapter 19.42 for the complete list of sign types and caps — Tables 3‑15 through 3‑19.)

Architectural & design controls

• All permitted signs that require a permit must meet the architectural and design sign standards in § 19.42.180. These emphasize complementary materials, unified sign themes for multi‑tenant sites, opaque sign panels, prohibition on exposed raceways/junction boxes, and limits on moving/flashing/animated signs. Design review and Comprehensive Sign Program may be required for multi‑tenant or freeway projects. See § 19.42.180 and § 19.42.190.

Permitting pathways & review authority

• Sign permit applications are filed with the Director and reviewed under the Code's review tables (site plan & design review / ARB as applicable). Comprehensive Sign Programs are required for multi-tenant developments, single-tenant projects >30,000 sf, and for C‑F zone projects. See § 19.42.050, § 19.42.060, and Chapter 19.122 (Site Plan and Design Review).

Checklist

• Determine base zone for the parcel (R‑, C‑G, C‑F, C‑P, H, M, I): consult the official zoning map and Table 1‑1.
• Identify sign types needed (wall, monument, hanging, window, A‑frame, freeway) and measure primary building frontage to compute allowable sq. ft. per § 19.42.110.
• Confirm whether a Comprehensive Sign Program is required (multi‑tenant projects, new C‑F projects, single‑tenant >30,000 sf). § 19.42.050.
• Prepare sign permit submittal: scaled elevations, mounting details, electrical/illumination plans (if illuminated), materials and color, site plan showing sign location and frontage calculation. § 19.42.060.
• For condos/CC&R-controlled properties: obtain written association authorization that allocates signs and parking before the City will issue sign permits (per condominium/subdivision requirements). § 19.85.040.
• If sign involves non‑Roman characters, include an English translation certification with the permit application. § 19.42.230.
• Verify required review authority (Director, ARB, Planning Commission, City Council) using the review tables (signs often reviewed by Director/ARB — see Table 7‑2 / Chapter 19.122).

Risks & Ambiguities

Plain-English Summary

If you own or lease property in Duarte, signs are governed by Chapter 19.42 — small residential signs are tightly capped, commercial and industrial signs are sized by frontage or site acreage, freeway and large multi‑tenant developments often require a unified Comprehensive Sign Program and design review, illuminated or moving signs face strict limits, and billboards are illegal. Apply for a sign permit, include the required materials (and any HOA/association authorization), and expect design review on larger or freeway‑oriented projects. See the specific zone table in Chapter 19.42 for the exact numeric caps. (§ 19.42.040; § 19.42.110; § 19.42.050)
