If you are planning a custom sign, the first thing you want to know is what it costs. That is a fair question, but it is harder to answer than it sounds.
Every day we field phone calls and emails that just want a quick quote over the phone or by the end of the day. Totally fair, we would want exactly the same quick answer if we were shopping for a sign.
Unfortunately, custom signage is not a product you pull off a shelf. Every sign is designed, engineered, and built for a specific building, a specific location, and a specific set of city requirements. Giving you a number without that context would be doing you a disservice. Here is why.
Every Building Is Different
Wall construction, mounting surfaces, electrical access, height, and structural capacity all affect how a sign is fabricated and installed. A channel letter set on a flat stucco wall is a different project than the same letters on a curved parapet or a stone facade.
Every City Is Different
Sign codes vary dramatically across Southern California. One city may allow illuminated signs up to 100 square feet. The next city over may cap you at 40 square feet with no illumination after 10 PM. These rules directly affect what can be built, which affects cost.
Your Landlord May Have Requirements Too
If you are in a shopping center or commercial complex, the property owner almost certainly has a sign criteria document (sign program). It may specify size limits, approved colors, letter styles, and mounting methods. We need to review that criteria before we can design or price anything accurately.
Design Affects Everything Downstream
The size, materials, lighting, and complexity of your sign all come together during design. Until we work through those decisions with you, any number we give would be a guess. And guesses lead to change orders, delays, and frustration.
We would rather take the time to give you an accurate price than a fast one that falls apart later.
What Custom Signs Typically Cost
The ranges below reflect what businesses in the Southern California market can expect to pay for common sign types. These cover fabrication and standard installation. Permitting, electrical work, and design fees are broken out separately below.
These are approximate ranges, not quotes. Your project may fall above or below these numbers depending on the factors covered in this guide.
Common Add-On Costs
Most projects include some combination of the costs below. These are separate from fabrication and installation.
Cost CategoryTypical RangeNotesElectrical Work$800 to $2,500+New circuits, wiring, timers, or panel upgradesPermitting Fees$500 to $2,000+Varies significantly by city and sign typeDesign and Engineering$500 to $3,000+Structural calcs required for most illuminated and freestanding signsOld Sign Removal and Wall Repair$500 to $3,000+Patching, painting, or rerouting electrical from a previous sign
What Drives Signage Costs
Size and Letter Count
Bigger signs require more materials, more LEDs, heavier mounting hardware, and often larger equipment for installation. A 10-letter channel letter set at 18 inches tall is a very different project than a 20-letter set at 36 inches. Size also affects permitting, since most cities calculate allowable sign area based on building frontage.
Materials and Construction
Aluminum channel letters with acrylic faces are the most common construction for illuminated signs. Upgrading to stainless steel, using thicker gauge metals, or specifying custom paint finishes increases both durability and cost. In coastal areas like Ventura or Santa Barbara, corrosion-resistant materials are not optional. They are a practical necessity.
Illumination
Illuminated signs cost more than non-illuminated signs. Within the illuminated category, the type of lighting matters. Standard white LEDs are the most cost-effective. RGB color-changing LEDs, halo-lit (reverse channel) letters, and exposed neon-style lighting each add complexity and cost.
Mounting and Installation Complexity
A raceway-mounted channel letter set on a single-story building is one of the simplest installations. Flush-mounted letters (no raceway) require more wall penetrations and wiring. Multi-story buildings may require crane access. Signs on stone, split-face block, or older construction may need structural reinforcement.
Location and Access
If your building is on a busy street, installation may require traffic control, early morning work, or coordination with the city. Tight parking lots, overhead obstructions, and limited crane access all add time and cost.
Why Design Comes Before Pricing
At Signature Signs, design is not a line item you can skip to save money. It is the step that makes everything else accurate.
Unlike many sign companies, we do not charge for design up front. We do that work regardless of whether you choose us for the project.
Before we fabricate anything, we create detailed mockups that show your sign on your actual building. You see exactly what the finished sign will look like in context: the scale, the colors, the proportions, and how it relates to the architecture.
This matters for three practical reasons:
- Accurate pricing. Once the design is finalized, we know exactly what materials, components, and labor the project requires. That is when we can give you a real number.
- Fewer surprises. Mockups catch problems early. If a sign is too large for the code, too heavy for the wall, or not quite right visually, we find out before materials are ordered.
- Smoother permitting. Submitting accurate, detailed drawings to the city increases the chance of approval on the first submission. Incomplete submittals get kicked back, potentially adding weeks to your timeline.
Landlord and Property Management Approvals
If your business is in a shopping center, office park, or any multi-tenant property, there is almost always a landlord approval process on top of city permitting.
Most commercial properties have a sign criteria document that specifies what is and is not allowed: maximum dimensions, approved letter styles, acceptable colors, illumination restrictions, and mounting methods. Some criteria are straightforward. Others are highly detailed and leave very little room for customization.
This step affects design and cost. If the landlord requires a specific letter style or restricts illumination, those constraints shape what can be built. We review the sign criteria early in the process so there are no conflicts between what the landlord allows, what the city permits, and what you are expecting.
Landlord approvals can also add time. Some property management companies respond quickly. Others take weeks. We account for this in the project timeline and follow up to keep things moving.
Landlord approval is also a prerequisite to permitting.
Permitting: The Timeline Factor Most People Don't Expect
Most exterior business signs in Southern California require a permit from the local building or planning department. This is one of the biggest factors in your project timeline.
What Permitting Involves
A typical sign permit submission includes scaled drawings of the sign and its placement on the building, structural calculations (for larger or illuminated signs), energy compliance documentation (Title 24 in California), and proof of property owner consent if you are a tenant.
How Long It Takes
Permit timelines vary widely by city. Some municipalities in Ventura County can process a straightforward sign permit in 2 to 4 weeks. Others take significantly longer. Glendale, for example, can take 8 to 16 weeks for sign permit approval due to application volume and design review requirements.
If your property falls within a special overlay zone or historic district, expect additional review steps and longer timelines.
Why This Matters for Your Budget
Permit fees typically range from $500 to $2,000 or more depending on the city and the type of sign. The indirect cost is time. A permit delay means your sign is not up, which means your business is harder to find. Planning for realistic permit timelines upfront helps you set expectations.
Signature Signs handles the entire permit process. We prepare the drawings, compile the documentation, submit to the city, and manage revisions if the city requests changes. We charge for our time on permit work and pass through city fees at cost.
What a Typical Project Timeline Looks Like
For a standard sign project in Southern California, expect roughly 8 to 12 weeks from your first conversation with us to completed installation. Here is how that time breaks down.

What Happens When You Cut Corners on Signage
We are not here to talk anyone out of shopping around. Comparing options is smart. But there are a few common shortcuts that consistently cause problems.
Skipping the site survey. A sign priced without seeing the building often leads to change orders once the installer shows up and finds conditions that were not accounted for. The savings disappear fast.
Choosing the lowest bid without comparing scope. A lower price sometimes means permits, electrical, and engineering are not included. When those costs surface later, the project ends up costing more than the higher bid that included everything.
Using cheap materials in a demanding climate. Southern California sun is relentless. Low-grade acrylic yellows. Thin paint fades. Budget LEDs fail early. A sign that needs to be repaired or replaced in three years is not a bargain.
Signature Signs backs permanent signage with a 3-year warranty covering materials, workmanship, and components. That warranty reflects our confidence in the materials and methods we use.
