Storefront Signs in Boulder

Storefront Signs for Boulder Businesses

Boulder's commercial corridors — Pearl Street, 28th Street, Arapahoe Avenue — are competitive retail environments. The city's Downtown district has specific sign restrictions on letter height and illumination. 303 Sign Company serves Boulder and Boulder County from our Longmont fabrication shop. We design, permit, fabricate, and install your sign with one team from start to finish.

We specialize in exterior signage that identifies your business at the storefront for Boulder businesses of all sizes — from single-location retail to multi-site commercial properties. Every project includes a fixed-price quote, professional permit drawings, and our own licensed install crew.

Types of Storefront Signs We Build

• Channel letters: Individually fabricated dimensional letters — the most visible and professional option for retail storefronts on busy corridors.
• Cabinet signs: An internally-lit box sign with a translucent face — cost-effective for large-format signage and franchises with specific sign criteria.
• Blade signs: Perpendicular signs projecting from the building face — ideal for pedestrian-heavy areas where foot traffic passes parallel to the storefront.
• Awning signs: Backlit or printed awnings that serve as both shade and signage — common in historic downtown districts.

Permitting in Boulder

Storefront signs require permits in virtually all Front Range cities. We handle the permit application and city coordination as part of every project. In Boulder, sign permits are submitted through the city's building or planning department. Timelines vary — we factor local permit lead times into every project schedule we give you.

What It Costs

Storefront Signs for Boulder businesses typically run $2,500–$15,000 depending on size, materials, and complexity. We provide fixed-price quotes — no surprises at installation.

Common Questions

What storefront sign type is best for my business?

It depends on your building, lease terms, and budget. Channel letters have the highest visual impact; cabinet signs offer the lowest cost per square foot. We'll recommend the right fit when we see your space.

Does my landlord need to approve the sign?

Usually yes — most commercial leases require landlord sign approval. We provide renderings and specs you can submit for approval before fabrication.

Can you match my franchise sign criteria?

Yes. We work with franchise sign criteria regularly and can fabricate to brand standards or approved alternates.
