D. Prevent property damage, personal injury, and litter caused by signs that are improperly constructed or maintained;

E. Protect and improve property values, the local economy, and quality of life by preserving and enhancing the appearance of the streetscape;

F. Provide clear and unambiguous sign design standards that enable the fair and consistent enforcement of these sign regulations; and

G. Ensure that the constitutionally guaranteed right of free speech is protected.

(Ord. 1646 § 2, 2022)

§ 20.360.002 Applicability.

A. This chapter applies to all signs in all zoning districts regardless of their nature or location, unless otherwise specifically exempted in Section 20.360.002(F) (“Exempt Signs”) or specified, constructed or physically altered on or after the Effective Date.

1. Standards for permanent signs are found in Section 20.360.006 (“Standards for Permanent Signs”).

2. Standards for temporary signs are found in Section 20.360.008 (“Standards for Temporary Signs”).

B. The provisions of this chapter shall be applied in a content-neutral manner. Noncommunicative aspects of all signs, not related to the content of the sign, shall comply with the provisions of this chapter. “Non-communicative aspects” include the time, place, manner, location, size, height, illumination, spacing, and orientation of signs.

C. Nothing in this chapter shall be construed to prohibit a person from holding a sign while picketing or protesting on public property that has been determined to be a traditional or designated public forum, so long as the person holding the sign does not block ingress and egress from buildings, create a safety hazard by impeding travel on sidewalks, in bicycle or vehicle lanes, or on trails, or violate any other reasonable time, place, and manner restrictions adopted by the City.

D. Substitutions and Interpretations.

1. This chapter is not intended to, and does not, restrict speech on the basis of its content, viewpoint, or message. No part of this chapter shall be construed to favor commercial speech over non-commercial speech. A non-commercial message may be substituted for any commercial or non-commercial message displayed on a sign, or the content of any non-commercial message displayed on a sign may be changed to a different noncommercial message, without the need for any approval or permit, provided that the size of the sign is not altered and the sign otherwise complies with the provisions of this chapter. To the extent any provision of this chapter is ambiguous, the term will be interpreted not to regulate on the basis of the content of the message.

2. This chapter applies to all signs within the City.

3. When there is any question regarding the interpretation of a provision of this chapter, or its application to any specific case or situation, the Chief Planner shall interpret the intent of this chapter.

4. All regulations included in this chapter shall apply unless a master sign program is approved by the Planning Commission; see Subsection 20.360.003(B) (“Master Sign Program”).

5. Review Authority. All Master Sign Programs are subject to review and approval of the Review Authority for the project with which the signs are associated, but at a minimum require approval by the Planning Commission. A Master Sign Program may be submitted as part of the Use Permit application for the project.

6. Required Findings. In order to approve a Master Sign Program, the Review Authority must find that all of the following are met, in addition to other applicable regulations in this section:

a. The proposed signs are compatible in style and character with any building to which the signs are to be attached, any surrounding structures and any adjoining signage on the site;

7. Lessees to Be Informed of Master Sign Program. Lessees within developments subject to the requirements of an approved Master Sign Program shall be made aware of the Master Sign Program in their lease.

8. Revisions to Master Sign Programs. Revisions to an approved Master Sign Program may be approved by the Chief Planner, or the Chief Planner may refer the matter to the Planning Commission.

C. Special Circumstances.

1. Purpose. Unusual site conditions, locations, particular unique signing requirements, or other design factors may warrant types, heights, and sizes of signs not otherwise permitted by the regulations of this chapter. Such signs, including, but not limited to, the following, shall require a Special Circumstances Sign Permit and shall be processed in accordance with Section 20.360.003(A) (“Permits Required; Review Process”).

a. Roof signs which extend above the highest point on the roof or of the type not allowed by Section 20.360.006 (“Standards for Permanent Signs”).

3. Required Findings. In order to approve a Special Circumstances Sign, the Review Authority must find that all of the following are met, in addition to other applicable regulations in this section.

a. The proposed signs are compatible in style and character with any building to which the signs are to be attached, any surrounding structures and any adjoining signage on the site.

b. Special circumstances exist that warrant consideration for exceeding the prescribed standards.

D. Relocation Agreements.

1. The regulatory provisions of this chapter are designed to accomplish the purposes included in Section 20.360.001 (“Purpose”) with respect to all signs reviewed and allowed in accordance with this chapter.

2. However, State law substantially limits the City’s ability to eliminate signs legally established prior to the adoption of this chapter, thereby frustrating the accomplishment of the purposes included in Section 20.360.001 (“Purpose”). Therefore, it is advantageous to utilize relocation agreements as authorized by Business and Professions Code Section 5412 to accomplish the purposes of this chapter with respect to such signs.

3. In order to facilitate the use of relocation agreements to accomplish the purposes of this chapter, signs expressly allowed by relocation agreements shall be exempt from design limitations under this chapter but shall be subject to staff-level design review to ensure compliance with any provisions in the relocation agreement as well as to ensure the best possible design consistent therewith. Except as set forth in this section, signs authorized by relocation agreements shall not be subject to any other design-related limitations not set forth within the relocation agreement itself.

4. No relocation agreement may be approved unless the City Council determines that it will accomplish the purposes of this chapter better than the status quo that it replaces.

5. No relocation agreement may provide for the construction or expansion of a sign in a residential district or for automatic changeable copy in which copy can be changed or altered by electric, electromechanical, electronic, or any other artificial energy means, except as set forth in Section 20.360.003(D)(6) below.

6. A relocation agreement may provide for the installation of a digital billboard provided that the City Council finds that all of the following are met:

a. The digital billboard is located in a nonresidential district, adjacent to U.S. Highway 101.

b. Installation of the digital billboard, containing up to two billboard faces, will result in a reduction of at least two billboard faces in the City for every digital billboard face installed. If a billboard applicant does not have sufficient existing billboard faces to remove within the City, the billboard applicant may request the City enter into a development agreement that will set forth the terms and conditions under which the billboard installation will be allowed to operate. The terms and conditions of such a development agreement may include, but are not limited to, the payment of fees, charges, and contributions as mutually agreed, and any such other terms which promote the public health, safety, and welfare in-lieu of applicant removing existing billboard(s) in order to satisfy the 2:1 removal-to-placement ratio requirement, as set forth in this subsection.

c. Installation of the digital billboard will advance adopted policies contained in the General Plan, and any applicable specific plan or area plan.

d. The digital billboard is operated in accordance with the operating standards set forth in Section 20.360.004(F)(7) (“Digital Billboards”).

Figure 20.360.004.A: Measuring Sign Area

a. Double-Faced Signs. For double-faced signs with less than 18 inches between faces, and less than a 30-degree interior angle between faces, only one side shall be counted as the total area. Where the faces are not equal in size, the larger sign face shall be used as the basis for calculating sign area.

Figure 20.360.004.B: Double-Faced Signs

b. Multi-Faced Signs. The sign area of signs with three or more sign faces, or signs with two sign faces with a distance greater than 18 inches apart or that have an interior angle greater than 30 degrees, shall be calculated as the sum of all the sign faces.

c. Three-Dimensional Signs. Signs that consist of, or have attached to them, one or more three-dimensional objects (i.e. balls, cubes, clusters of objects, sculpture, or statue-like trademarks), shall have a sign area of the sum of two adjacent sides or sign faces.

Figure 20.360.004.C: Three-Dimensional Signs

2. Measuring Sign Height. The height of a sign is the vertical distance from the uppermost point used to measure sign area to the existing grade immediately below the sign or to the top of the nearest curb of the street on which the sign fronts, whichever measurement is the greatest.

3. Measuring Sign Clearance. Sign clearance shall be measured as the smallest vertical distance between finished grade and the lowest point of the sign, including any framework or other embellishments.

4. Building Frontage. A building’s frontage is considered continuous if projections or recesses in a building wall do not exceed 10 feet in any direction. For buildings with two or more frontages, the length of the wall and allowable sign area shall be calculated separately for each building frontage.

Figure 20.360.004.D: Building Frontage

A Building Permit shall be issued prior to installation of any new signs requiring electrical service.

b. All permanent signs allowed by this chapter shall be constructed of durable materials capable of withstanding continuous exposure to the elements and the conditions of a built-up environment, and shall be permanently attached to the ground, a building or another structure by direct attachment to a rigid wall, frame, or structure.

2. Signs shall be designed so that the support frameworks for the sign are an integral part of the design of the sign or within the structure of the building to which it is attached in such a manner as to not be visible. Any angle iron, bracing, guy wires, or similar features used to support a sign shall not be visible to the extent technically feasible.

3. Raceway cabinets, as illustrated in Figure 20.360.004.F, must only be used in building mounted signs when access to the wall behind the sign is not feasible, or when the Chief Planner determines that a benefit exists to preserve a historic or architectural feature of a building. In such cases, the raceway cabinet must not extend in width and height beyond the area of the sign and must match the color of the building to which it is attached. Where a raceway cabinet provides a contrast background to sign copy, the colored area is counted in the total allowable sign area allowed for the site or business.

Figure 20.360.004.F: Raceway Cabinet

H. Sign Maintenance. Each sign displayed within the City, including exempt signs, shall be maintained to comply with the following standards:

1. All signs shall be maintained by any property owner, lessor, lessee, manager, agent, or other person having lawful possession or control over a sign, building, structure, or parcel of land, in a condition or state of equivalent quality to which it was approved or required by the City.

2. All signs together with their supports and appurtenances must be maintained in good structural condition, in compliance with applicable Building Codes, and in conformance with this chapter. Maintenance of a sign includes annual cleaning; replacement of flickering, burned out or broken light bulbs or fixtures; repair or replacement of any faded, peeled, cracked, or otherwise damaged or broken parts of a sign; replacement of broken or removed components of the sign; and any other activity necessary to restore the sign so that it complies with the requirements and contents of the Sign Permit issued for its installation and the provisions of this chapter.

3. The Building Official is authorized to order the repair, maintenance, or removal of any sign or sign structure that has not been maintained and is dangerous or in disrepair, or which is erected or maintained contrary to the requirements of this section.

4. Failure to maintain a sign constitutes a violation of this chapter and will be subject to enforcement action, in which case the Building Official may order the removal of any sign that is determined to be in disrepair or dangerous.

5. Any owner of a sign victimized by graffiti shall remove, repair, or repaint sign(s) within two days of notice of the graffiti’s placement on the sign.

6. Abandoned signs shall be removed in compliance with the following requirements. Any sign not removed within the required period shall constitute a nuisance and shall be removed pursuant to the procedures set forth in Division 3, Chapter 2.6 of the Business and Professions Code (Section 5499.1 et seq.).

(Ord. 1646 § 2, 2022)

§ 20.360.005 Sign Design Standards.

A. Applicability. The standards established in this section apply to all permanent signs. These standards complement the mandatory sign regulations established in Section 20.360.006 (“Standards for Permanent Signs”).

B. General Sign Design Standards. These general sign design standards will be utilized during the review of all permanent signs for which a Type A, Type B, or Type C Sign Permit (see Section 20.360.003(A) (“Permits Required; Review Process”)) is required to ensure the highest level of design quality, while at the same time providing the flexibility necessary to encourage creativity on the part of the sign designer. However, unless there is a compelling reason, these design standards must be observed.

C. Use a Brief Message. Signs must be designed with a brief message because the fewer words used, the more effective the sign. A sign with a brief message is quicker and easier to read, looks cleaner, is more effective in conveying its message, and is more attractive.

D. Avoid Overly Intricate or Unusual Fonts. Simple, easy-to-read fonts must be utilized in signs to enhance their readability. Signs that include very intricate font styles are generally difficult to read and reduce a sign’s ability to communicate effectively. Signs with unusual fonts may look good today, but soon go out of style, and the image conveyed may quickly become that of a dated and unfashionable business.

Figure 20.360.005.A: Examples of Signs with a Brief Message and Simple Font Style

E. Emphasize One Line of Text. Signs with more than one line of text must emphasize one line over the others to enhance the message conveyed.

F. Limit the Number of Fonts. The number of fonts used in a sign must be limited because the use of more than two font styles makes the sign harder to read. The primary purpose of a sign is to quickly convey information to motorists and pedestrians.

G. Sign Colors and Materials. Sign colors and materials must contribute to sign legibility and design integrity. Signs with poor color selection are generally unattractive and unsuccessful at communicating the message. Too many different colors compete with the sign’s content for a viewer’s attention and makes the sign less effective. Sign materials must be durable and weather-resistant.

H. Provide Contrast Between Background and Letters/Symbols. Signs must be designed with high contrast between the sign’s letter/symbol color and its background color to be most effective. Signs with little contrast in the hue (shade or tint) and/or intensity (brightness) between the background and letter/symbol colors are difficult to read.

Figure 20.360.005.B: Examples of Signs with a Simple Color Palette, Limited Fonts, and Good Contrast

I. Graphic Relief. Signs must utilize individual lettered business and logo design, or where appropriate, sign copy, logo, and/or decorative embellishments in relief on the face of the sign to enhance readability and project a positive image of the business or use. Signs must be designed to provide three-dimensional relief, i.e. be raised above, or set below the sign background.

Figure 20.360.005.C: Examples of Raised Letters

J. Sign Placement. Signs must be placed at or near the entrance of a site or building to show the most direct access to the business.

Figure 20.360.005.D: Examples of a Well-Placed Sign Emphasizing a Building Entrance

K. Proportion, Scale and Rhythm of Sign Placement. Signs must be placed consistent with the proportions and scale of building elements within a building’s façade:

1. A large sign may fit well on a large, plain wall area, but could overpower the finer scale and proportion if placed above a small storefront.

2. Signs must establish rhythm, scale, and proportion on a façade where these elements are weak in the building design. On buildings with plain façade, signs must establish or continue appropriate design rhythm, proportion, and scale.

3. The proportion of letter area to sign background area must be carefully considered. Letters must not appear to occupy more than 70 percent of the sign’s background area. Signs where the letters take up too much of the background area are harder to read. Generally, large letters are not necessarily more legible than smaller ones.

Figure 20.360.005.E: Examples of Signs with Good Proportion, Scale, and Rhythm

L. Complementary Sign Design. Where there is more than one sign for a business (e.g., single tenant buildings) or group of businesses (e.g., multiple tenant buildings, commercial centers, or business or industrial parks), all signs must be designed to ensure consistency of sign design and be complementary to one another in the following ways:

1. Type of construction materials used in the sign body, sign copy, sign base, supports, etc.;

2. Letter size and style of copy;

3. Method and design of sign support (wall mounting or monument base);

4. Configuration of sign area; and

5. Proportion of sign copy area to background.

M. Artistry and Innovation. The use of artistry and innovation in sign design will make the sign stand out and draw attention to the use or activity it is advertising. It can also improve the overall appearance of a building or neighborhood.

N. Sign Scale. Signs must be designed and placed relative to who the intended viewer will be. Signs intended to be read by pedestrians (i.e. usually read from a distance of 15 to 20 feet) must be smaller in scale than a vehicle-oriented sign which is designed to be viewed from a much greater distance. In general, the closer the sign’s viewing distance, the smaller the sign needs to be.

O. Freestanding Signs. Freestanding signs must incorporate the materials and architectural features used in the building(s) they serve. Freestanding signs are most effective when placed perpendicular to approaching vehicular traffic.

Figure 20.360.005.F: Example of a Freestanding Sign Incorporating the Architectural Details of the Main Building

(Ord. 1646 § 2, 2022)

(Ord. 1646 § 2, 2022)

§ 20.360.008 Nonconforming Signs.

A. A nonconforming sign is a sign lawfully constructed and maintained prior to the effective date, but which does not conform to the provisions of this chapter, or because of a district change after the effective date affecting the property upon which the sign is located, ceases to comply with the applicable zoning district regulations. This chapter is intended to limit the number and extent of nonconforming signs by prohibiting the alteration or enlargement of nonconforming signs, thereby reducing the discrepancy between existing conditions and the standards and requirements of this chapter, and to provide for the elimination of nonconforming signs in residential districts, in compliance with State law.

B. No nonconforming sign shall be altered, enlarged, relocated, and/or reconstructed, except in such manner as to comply with the requirements of this chapter or as authorized under a Relocation Agreement in compliance with Section 20.360.003(D) (“Relocation Agreements”). A nonconforming sign may be maintained or its text changed without affecting its nonconforming status.

C. Repair or Reconstruction of Damaged or Destroyed Signs. A nonconforming sign destroyed or damaged to the extent of 75 percent or greater of its fair market value as of the date of such destruction or damage is not a nonconforming sign pursuant to this chapter and shall be removed or repaired to conform with all applicable provisions of this chapter.

D. Alteration. Except as provided below, no nonconforming sign shall be altered or moved unless such alteration or moving reduces the degree of nonconformity.

1. A nonconforming sign may be removed from the building or structure to which it is attached for purposes of repair providing it is returned to the same place from which it was removed within 14 days after removal, and further providing there is no increase in size or change of copy.

2. Signs which reflect the unique historical characteristics of the development and heritage of South San Francisco may remain, subject to continued maintenance, until the use of the site on which the sign is located changes, subject to Planning Commission approval based on the following findings:

a. The sign existed at the effective date and was originally erected at least 30 years prior to the date of the application.

b. Based on a report from the Chief Building Official, the sign is structurally sound and complies with the provisions of the current building and associated codes.

c. The design of the sign is common to the period in which it was built, is consistent with the structures on the site, and complements the unique characteristics of South San Francisco.

d. The sign is maintained in compliance with provisions of Section 20.360.004(H) (“Sign Maintenance”). Continued maintenance shall be a condition of approval of the permit.

e. Retaining the sign will not result in visual clutter or blight and will not adversely affect the adjoining properties.

E. Removal or Replacement of a Nonconforming Sign. Removal of a nonconforming sign, or replacement of a nonconforming sign with a conforming sign, is required when:

1. A building is renovated and the cost of the renovation is 50 percent of more of the value of the building as determined by the Building Official or the building is demolished and rebuilt; or

2. The use of the sign and/or the property on which the sign is located has been abandoned, ceased operations, become vacant, or been unoccupied for a period of 90 consecutive days or more as long as the period of non-use is attributable at least in part to the property owner, tenant, or other person or entity in control of the use. For purposes of this section, rental payments or lease payments and taxes shall not be considered as a continued use. In the event this should occur, such conditions will be considered as evidence of abandonment, requiring removal of the sign by the owner of the property, his/her agent, or person having the beneficial use of the property, building or structure upon which such sign or sign structure is erected within 30 days after written notification from the Chief Planner. If, within the 30-day period, such sign(s) is (are) not removed, enforcement action shall be pursued.

(Ord. 1646 § 2, 2022)

§ 20.360.009 Enforcement, Liability, and Penalty.

A. Liability for Damages. The provisions of this chapter shall not be construed as relieving or limiting in any way the responsibility or liability of any person erecting or owning any sign for personal injury or property damage resulting from the placing of such signs, or resulting from the negligence or willful acts of such persons, their agents, employees or workers in the construction, maintenance, repair or removal of any sign. Nor shall this chapter be construed as imposing upon the City, or its officers, or employees any responsibility or liability by reason of the approval of any signs, materials or devices under the provisions of this chapter.

B. Enforcement. It shall be the duty of the Code Enforcement Officer to enforce the provisions of this Ordinance; referrals may be made by the Planning Division, Building Division, or Police Department.

C. Violations. If the Code Enforcement Officer finds any sign not complying with the regulations of this Ordinance, written notice shall be given to the sign owner and to the property owner. The notice shall specify the time period within which compliance must be achieved. If the sign owner or the property owner fails to remove or alter the sign so as to comply with the standards herein set forth after such notice, the Code Enforcement Officer may cause such sign to be removed, or altered to comply, at the expense of the sign owner or owner of the property upon which it is located.

D. Removal. Notwithstanding the foregoing, the Chief Building Official, Code Enforcement Officer, Director of Public Works or Police Department may have removed without prior notice any sign which is an immediate threat to persons or property or which is located on public property in violation of this chapter. Once such a sign is removed the Code Enforcement Officer shall immediately attempt to notify the owner of the sign, if ascertainable. If the sign is not retrieved within 15 days after removal, it shall be deemed abandoned and may be disposed of by the City.

E. Penalty for Violation. Any person violating a provision of this chapter or failing to comply with a mandatory requirement of this chapter shall be guilty of a misdemeanor and, upon conviction, such person shall be punished as set forth in Chapter 1.24 (“General Penalty”) of the South San Francisco Municipal Code.

(Ord. 1646 § 2, 2022)
