Building Signs Chicago — Large-Scale Facade and High-Rise Signs by TFA Signs

Building signs establish identity at scale — they are the large-format dimensional letters, illuminated cabinets, and architectural signage installed on the facades of office towers, retail centers, hotels, hospitals, stadiums, warehouses, and commercial properties in Chicago. TFA Signs installs large-scale building signs throughout Chicago, with expertise in high-elevation installations using cranes, boom lifts, and rigging equipment that our installation crew operates directly. Our in-house rigging capability means we do not subcontract high-access installations — our own team controls quality and safety from ground to rooftop.

Building sign fabrication at TFA Signs begins with structural engineering. For signs installed at height or on building facades, we calculate wind load based on the sign's projected area and installation height, specifying fastener sizes and spacing to meet the required load factors. We produce permit-ready structural engineering drawings stamped by a licensed structural engineer. This documentation is submitted to the Chicago Department of Buildings as part of the sign permit application. Without this engineering, large building signs cannot be permitted in Chicago. TFA Signs manages this engineering and documentation process on behalf of clients as a standard part of our project management.

The most common building sign type is large-format dimensional aluminum letters. These are CNC-routed from thick aluminum plate or formed aluminum, with either a painted finish or a polished/brushed metal finish. They are installed on a grid of threaded studs anchored into the building facade, creating a flush or slightly projected three-dimensional effect. Illuminated versions use LED strips inside the letter cavity for front lighting, or behind the letters for halo illumination. TFA Signs has installed dimensional building letters up to 6 feet tall on Chicago high-rise facades along Wabash, Michigan Ave, and in the River North and West Loop districts.

For buildings seeking illuminated signage with changeable graphic capability, illuminated cabinet signs or LED panel displays can be installed as facade signs. These are custom-fabricated to specific dimensions and integrated into the building facade or mounted on a structural frame. TFA Signs engineers the mounting system to attach to the building's structural elements safely, and all electrical work is performed by our licensed Chicago electricians. We coordinate with building management, structural consultants, and city inspectors throughout the process.

Frequently Asked Questions — Building Signs Chicago

Do building signs need structural engineering in Chicago? Yes. The Chicago Department of Buildings requires stamped structural engineering drawings for building signs over a certain size and for all signs at elevated heights. TFA Signs coordinates this engineering as part of our permit process.

Can you install building signs without shutting down the street? For many installations, we work from within the building or from a boom lift in a parking lane with proper traffic control permits. For larger crane lifts, brief lane or street closures may be required — we coordinate all necessary traffic control permits with CDOT.
