Interior Signage for Building Projects

One package, four systems

Most buildings end up with mismatched signage because signs get bought one problem at a time: a room gets repurposed, a wing gets renovated, an inspector flags a door, and each fix comes from a different vendor with different fonts, colors and mounting heights. A coordinated interior sign package avoids that by treating ADA signage, room identification signs, wayfinding signage and interior graphics as one specification instead of four separate purchases.

That specification lives in a sign schedule: a list of every sign location, message, size and mounting height across the building, tied to a single numbering scheme. On a designed project, the architect or a signage consultant issues the sign schedule as part of the construction documents. On a facility-driven project with no architect in the loop, we build it from a field survey of the existing building plus your room numbering, so the same document controls both the ADA-required signs and the plain directional signs.

How the four systems actually differ

The most common misunderstanding on a sign package, and the one that costs facility managers the most in rework, is treating every interior sign as if it needs the same level of compliance.

ADA signage covers signs identifying permanent rooms and spaces: restrooms, room numbers, stairwells. These require both tactile characters with Grade 2 braille and visual character compliance (2010 ADA Standards 216.2). Signs identifying the doors at exit stairways, exit passageways and exit discharge carry the same dual requirement (2010 ADA Standards 216.4.1), while area of refuge instructions and directional signs to accessible exits need visual characters only (216.4.2, 216.4.3).

Room identification is the layer that carries your actual numbering and naming convention: suite numbers, department names, staff nameplates. Where a room ID sign identifies a permanent space, it inherits the ADA tactile and braille requirements above.

Wayfinding signage, meaning directional arrows, overhead signs, directories and floor-level maps, is scoped differently. Directional and informational signs need only meet visual character requirements (2010 ADA Standards 216.3), and building directories are exempt from Section 216 altogether (216.1 Exception 1). Raised characters and braille are not required on either. Specifying tactile wayfinding signs is not a compliance requirement, it’s an unnecessary cost.

Interior graphics (wall graphics, murals, window film, dimensional letters, privacy film) are typically outside ADA scope entirely and give you the most design latitude in the package, which is why they usually get specified last, once the compliance-driven signs are locked.

For a full walkthrough of the compliance requirements with cited section numbers, see our ADA signage requirements guide.

Phasing work in an occupied building

Almost none of our interior signage work happens in an empty building. A tenant improvement, a partial renovation or a numbering-scheme update usually has to proceed while staff, tenants or the public are still using the space.

That changes the sequence. Instead of installing an entire floor at once, we phase by wing or by floor, matching your occupancy schedule so a corridor isn’t out of service and a department isn’t unreachable mid-install. We leave the existing signs up until the new set physically replaces them, so the building is never without its required signage. That matters most for egress signage, including the tactile exit door signs required by 2010 ADA Standards 216.4.1, where a gap between old and new is not an option.

What we need to quote your project

The fastest path to a real number, not a placeholder range, is:

• A floor plan or existing sign schedule
• Sign quantities by type (ADA room ID, directional, egress, graphics)
• Photos of existing signage if you’re matching a current standard
• Target install date
• Whether the building will be occupied during install

If you have architectural drawings with a Division 10 14 00 sign schedule already in them, send those directly. If you don’t have drawings, a field survey is how we build the schedule from what’s actually on your walls today: we walk the space, record every room, door and corridor that needs a sign, and note anything that doesn’t match current code so it gets flagged before it becomes a punch list item.

That upfront accuracy matters more on a sign package than it does on most other trades, because a wrong room number or a mis-specified mounting height doesn’t surface until install, and by then it’s a change order instead of a line on a drawing.

Where this shows up across Lake County

The building types driving most of this work in Lake County are consistent: hospital and clinic renovations around Northwestern Medicine Lake Forest Hospital and Advocate Condell Medical Center in Libertyville, campus buildings at the College of Lake County and the county’s larger school districts, tenant improvements in office parks near Vernon Hills and Deerfield, and warehouse and distribution buildings in industrial parks like Bridge Point North in Waukegan. Each of those building types has its own mix of compliance-driven and directional signage, and we cover the specifics on our industries pages.

Geography matters on scheduling more than people expect. North-south travel along I-94 and US-41 is fast, but east-west corridors like IL-132, IL-120 and IL-60 run through signaled surface streets, so a site 15 miles from Gurnee by road can take twice as long to reach as the distance suggests. We factor that into install scheduling rather than assuming every stop in the county takes the same time.

Submittals through closeout

On projects that require formal submittal review, we provide shop drawings for approval before fabrication starts, so the sign schedule, message content and mounting details are confirmed in writing before anything gets made. After install, we walk the punch list with you, correct anything flagged, and deliver as-builts documenting final sign locations and specifications for your facility records.

Whether you’re a facility manager maintaining a building you inherited or a general contractor closing out a tenant improvement, that closeout package is what makes the next sign order, years from now, match the one we just finished. We also work across Lake County’s major building types, from healthcare to schools to industrial facilities; see our industries page for specifics by sector.
