From Torrey Pines biotech campuses to Gaslamp Quarter storefronts and Coronado resort properties, United Signs designs, permits, and installs signage built for San Diego's coastal climate and diverse commercial landscape.
San Diego's commercial market spans biotech campuses in Torrey Pines, resort properties in Coronado, defense corridors in Sorrento Valley, and neighborhood retail across all 18 cities in the county. Each environment demands signage that fits its surroundings, holds up against salt air and coastal UV exposure, and clears the city's layered review process covering historic properties, coastal zones, and scenic corridors. United Signs designs, fabricates, and installs custom signage for every corner of San Diego County, with a local team that handles every stage from first concept to final inspection.
From concept to installation, our San Diego signage services are designed to deliver lasting impact for businesses across California.

Our San Diego team understands DSD permit timelines, the sign code distinctions between coastal zones and inland communities, and the engineering demands of California's structural and climate requirements.
Clear answers to the permit, compliance, and coverage questions San Diego businesses ask most.
The City of San Diego Development Services Department issues all sign permits, submitted through the city's online portal. A permit is required for any new sign installation or alteration. Applications include a site plan, elevation drawings, a sign schedule, and structural calculations where needed. United Signs prepares and submits all documentation on every project. n
A building permit is required instead of a standard sign permit when a ground or monument sign exceeds 7 feet in height, when the installation involves structural changes to an existing building, or when a structural reviewer determines one is needed after reviewing calculations. We identify the correct permit type at the start of every project. n
Properties with structures 45 years or older may require a historic review before a sign permit is issued. Depending on the outcome, additional constraints on sign materials, dimensions, or illumination may apply. We check historic review applicability at the start of every project. n
Yes. Digital and electronic signs are prohibited in residential zones and restricted in coastal zones, scenic corridors, and historic districts. In qualifying commercial zones, digital displays must meet California lighting standards and may be subject to additional community design review. We assess digital sign eligibility by zone before design begins. n
Yes. Signs we build for the San Diego market use marine-grade hardware to resist salt air corrosion, UV-stable coatings for Southern California's sun exposure, and sealed electrical components for coastal moisture conditions. Structural components are engineered to California wind load standards where required. n
