Riverside — Signage

Last reviewed: July 3, 2026

Overview

Riverside regulates signs in Title 19 (Zoning), Chapter 19.620 (Sign provisions). The rules define what counts as a sign, exempted sign types, prohibited signs, dimensional limits by use/district, the sign permit process, sign programs for multi-tenant sites, and special chapters for signs on City property and freeway-oriented signs. See the city’s purposes and scope at § 19.620.020 and § 19.620.030 for the controlling policy statements and applicability.

District-by-district breakdown (Riverside rules)

Notes on sources and reading: the sign standards are organized in Chapter 19.620 (and related chapters 19.625, 19.623, 19.670) of the Zoning Ordinance; where a standard is in a table the controlling reference is shown as § 19.620.080 or the table name. Citations below show the controlling § and the ordinance file preview.

Residential zones (all residential zones; special RA-5 rule)

Purpose & where it applies

• Rules for signs on private residential properties are located in § 19.620.080.C; applicability of the sign chapter to all zones is in § 19.620.030.

Typical permitted uses (sign types)

• Single-family and duplex: one on-premises building- or freestanding sign per dwelling up to 3 sq ft and 3 ft high (non‑commercial, except real‑estate temporary signs) — § 19.620.080.C.2.a.
• Planned residential developments / multi‑family / mobile home parks: one on‑premises monument or building sign up to 25 sq ft per street frontage; monuments limited to 6 ft overall height; alternate allowance: two wall signs (25 sq ft each) at project entries — § 19.620.080.C.2.b.
• RA-5 (Residential Agricultural) exception: one unlighted monument sign up to 12 sq ft and 6 ft high is allowed — § 19.620.080.C.3.

Key constraints

• Residential window signs limits and temporary sign rules apply (see § 19.620.080.C and § 19.620.090 for temporary signs).

Where to check on-site specifics

• If a residential site is part of a mixed-use or overlay district, follow the zone/overlay rules; verify with Planning for any site‑specific design review triggers — § 19.620.100.

Commercial & Mixed‑Use zones

Purpose & where it applies

• General permanent sign standards for nonresidential and mixed‑use districts are in § 19.620.080.B; building‑mounted rules are in Table 19.620.080.A, freestanding sign rules in Table 19.620.080.B, and special uses in Table 19.620.080.C.

Typical permitted uses and numeric standards

• Wall signs: baseline allowance is 1 sq ft of sign area per lineal foot of occupant building frontage (see Table 19.620.080.A) — § 19.620.080.A.
• Monument/pylon allowances depend on site size (see Table 19.620.080.B); small sites (<1 acre) generally limited to one monument sign ~30 sq ft and 6 ft high; larger commercial complexes get additional allowances per frontage — § 19.620.080.B.
• Vehicle fuel stations have specific allowances: Freeway‑oriented pylon sign up to 100 sq ft / 45 ft tall, price/monument sign up to 50 sq ft and 8 ft high for major frontage; secondary price signs limited to 15 sq ft / 6 ft high — Table 19.620.080.C.

Key process & design controls

• Permanent signs in nonresidential/mixed‑use zones are subject to design review / Citywide Sign Design Guidelines; a sign program is required for multi‑occupant developments (3+ tenants) — § 19.620.080.B.1, § 19.620.110.

Where it applies

• Applies to standard commercial zones and mixed‑use zones across the city; for projects inside a Specific Plan or overlay, check overlay provisions first. Verify with Planning when frontage configuration or complex composition is unusual — § 19.620.080.B.4–5.

(See the "decision‑relevant standards" table below for the most common numerical rules and the code references.)

Business Manufacturing Park (BMP) & General Industrial (I) Zones

Purpose & where it applies

• Industrial zones have special on‑site notification sign requirements when a discretionary permit (Minor CUP or CUP) is required; these are in § 19.670.130 (Notice of Filing signage for new development in BMP & I zones).

Typical permitted signage

• BMP & I are otherwise governed by the general nonresidential sign rules (Tables 19.620.080) but with attention to industrial notice sign rules (e.g., 4' x 8' posted notice sign when certain permits are processed) — § 19.670.130 and § 19.620.080.

Key constraints

• Industrial project notice signs: 4 ft x 8 ft, mounted on stakes 6 ft or higher, posted on each public street frontage and meeting timing/maintenance rules — § 19.670.130.

Neighborhood Commercial Overlay Zone (overlay)

Purpose & where it applies

• The code makes specific accommodation for small projecting/blade signs in Neighborhood Commercial Overlay Zones: a max 4 sq ft double‑faced projecting sign may substitute for an under‑canopy sign with projection and clearance limits — § 19.620.075.A.5.b.

Typical permitted signage

• Blade/projecting sign: ≤ 4 sq ft, projection up to 30 in, lowermost portion 8 ft above grade by rule in the overlay — § 19.620.075.

Key constraints

• If projecting into the public right‑of‑way you must obtain an encroachment permit — § 19.620.075.A.6 & § 19.625.090.

Pedestrian Mall / Downtown / Special districts

Purpose & where it applies

• The code contains specialized rules for pedestrian mall signs (A‑frame / sidewalk signs), including insurance and permit renewals for public mall locations, in Section 19.620 (see the pedestrian mall subsections).

Typical permitted signage

• Pedestrian mall sidewalk (A‑frame): max 12 sq ft, max height/width 4 ft, must be weighted, professional quality, and removed indoors at close of business; permits and annual renewal required, plus liability insurance naming the City — § 19.620 (pedestrian mall rules).

Key constraints

• Insurance and renewal requirements; minimum clearances; cannot attach balloons/flags to the sign; City can refer designs to Cultural Heritage Board or Planning Commission — § 19.620 pedestrian mall subsections.

Historic resources and design‑sensitive areas

Purpose & where it applies

• Signs that affect designated historic resources or historic districts have special rules (Certificate of Appropriateness, historically appropriate lighting, replication of historic roof signs where documented) — see § 19.620.120 and related provisions.

Typical permitted signage

• Historic reproductions allowed with Certificate of Appropriateness; sign lighting limited to historically appropriate types but must meet structural and electrical codes — § 19.620.120.

Key constraints

• HPO / Cultural Heritage Board may not consider message content for noncommercial signs but can require visual compatibility; Certificate of Appropriateness and Title 20 procedures apply. Verify with Historic Preservation staff — § 19.620.120.

Decision‑relevant standards (quick reference table)

Practical guidance & plain‑English synthesis

• Permits: Most permanent sign work requires a sign permit and, if structural/electrical changes are involved, building permits — see § 19.620.100 (permits generally required) and the rule that a sign requiring design review or a Certificate of Appropriateness must receive those approvals before a sign permit will be issued.
• Design & context: Commercial signs must follow the Citywide Sign Design Guidelines and often must be part of a unified sign program for multi‑tenant complexes — § 19.620.110.
• Where the sign sits (ROW, private property, City property): private signs on City property and signs in the ROW are governed by Chapter 19.625 (private party signs on City property / ROW); signs projecting into the ROW also need an encroachment permit — § 19.625.030–100 and § 19.625.090.
• Prohibited types: Riverside broadly prohibits pole signs, portable signs (unless expressly allowed), animated/moving signs, bench signs, advertising statuary, and permanent off‑site advertising billboards unless separately authorized — § 19.620.050.
• Historic areas: special historic sign rules and Certificate of Appropriateness apply — § 19.620.120.
• Nonconforming signs: existing legal nonconforming signs may remain but cannot be enlarged/moved unless brought into compliance — § 19.620.130.

Practical tip: Measure sign area exactly per the code’s calculation rules and figures (sign area rules in § 19.620.070) before applying; disputes about frontage or which face counts are common — § 19.620.070.

Checklist (what an applicant must satisfy)

• Confirm which zoning district(s) and overlays apply to the parcel; check for overlay exceptions. Verify with Planning. § 19.620.030.
• Calculate allowed sign area and height using § 19.620.070 and the applicable Table 19.620.080 entry for your use type.
• Determine whether a sign permit is required (most permanent signs are); submit the sign permit application with drawings per § 19.620.100.
• If the site is multi‑tenant (3+), prepare a sign program per § 19.620.110.
• If the sign projects into the public right‑of‑way or encroaches on City property, obtain an encroachment permit (Public Works) per § 19.625.090.
• If electrical/structural changes are required, get the necessary permits under the California Building Standards Code / Title 24 (verify Building & Safety) — sign permits will not be issued until required approvals are in place § 19.620.100.
• Check prohibited sign types (pole signs, animated signs, portable signs, billboards) before planning design — § 19.620.050.
• If the sign is on or affects a designated historic resource, obtain a Certificate of Appropriateness per § 19.620.120.
• Secure written property owner consent for any sign on property you do not own; maintain sign per § 19.620.075 (maintenance/safety).

Risks & Ambiguities

Plain‑English summary

Riverside’s sign code (Title 19, Chapter 19.620) sets who can put up what kind of sign, how big it can be, how high it can be, and where it can go; commercial projects generally get more sign area but must meet design guidelines and often a sign program, some sign types (billboards, pole signs, animated signs) are broadly prohibited, and signs in the public right‑of‑way or on City property need special permits — see § 19.620.020, § 19.620.080, § 19.620.100, and § 19.625.090 for the controlling rules.
