Imperial Sign Crafters is a sign company founded in 2017 and based in Summerville, South Carolina that serves Johns Island, SC. It built the Millers Crossing community entrance monument on Johns Island and designs and produces monument signs, exterior and interior business signs, vinyl signage, custom signage, vehicle wraps and community mailbox kiosks. Johns Island is split between the City of Charleston and unincorporated Charleston County, and each reviews signs under its own rules.
What have we built on Johns Island?

The Millers Crossing community entrance monument is the Johns Island project in our project gallery. It is entrance signage built for a neighborhood instead of a single business, which is the kind of sign the island needs most as it grows.
An entrance monument here has to look like it belongs among the live oaks and open land, hold up to coastal weather, and sit far enough back to keep sight lines clear at the drive. Those three things shape the design more than the lettering does.
Who approves a sign on Johns Island?
Johns Island is split between the City of Charleston and unincorporated Charleston County, and the line is not obvious from the road. Check your parcel before you do anything else.
| If the parcel is in | Who reviews the sign | What to expect |
|---|---|---|
| City of Charleston limits | City of Charleston Zoning Division | Electrical permit if illuminated; extra design review applies only in designated districts |
| Unincorporated Charleston County | Charleston County Zoning and Planning | Online application with a scaled site plan, the vision clearance triangle at the drive, sign drawings, lighting details, wind and dead load construction drawings and a signed affidavit |
| Either, with a planned development or overlay | The same office, plus the PD or overlay terms | Development or overlay rules can be stricter than the base district |
We do not publish fees, size limits or timelines here. Confirm them for your parcel with the office that has jurisdiction.
What sign work does Johns Island need?
Most of the island's commercial activity sits along Maybank Highway, River Road and Bohicket Road, with new neighborhoods filling in between farms and open land. It is also the road to Kiawah and Seabrook, so a lot of traffic passes through. Requests here fall into a few groups:
- Neighborhood entrance monuments and mailbox kiosks for new and growing communities
- Monument signs for small commercial centers, offices and churches set back from the road
- Building signs and window lettering for shops and restaurants along Maybank Highway
- Vehicle lettering for landscapers, builders and service companies working the island and the resorts
Signs that work here tend to be simpler and more material-driven than suburban signs: natural finishes, masonry bases and clean lettering that reads at highway speed.
What signs do we make for Johns Island properties?
We build the sign types on our sign services page:
- Monument signs for businesses, churches, offices and community entrances
- Exterior business signs for storefront and building-mounted identification
- Interior business signs for lobbies, reception walls and offices
- Vinyl signage for windows, doors, walls and vehicles
- Custom signage built for a specific site or brand
- Vehicle wraps, partial wraps and lettering for trucks, vans and trailers
- Community mailbox kiosks and pavilions for HOAs, apartments and new developments

Johns Island sign questions
Have you built signs on Johns Island?
Yes. We built the Millers Crossing community entrance monument on Johns Island, which is in our project gallery. Imperial Sign Crafters is based at 709 Miles Jamison Rd, Suite 2, Summerville, SC 29485 and works across the island.
Who approves a sign on Johns Island?
Johns Island is split between the City of Charleston and unincorporated Charleston County. Inside city limits, the City of Charleston Zoning Division handles sign approval. In the unincorporated areas, Charleston County Zoning and Planning reviews sign permits. Check which side of the line your parcel is on first.
What does Charleston County ask for on a sign permit?
The county's freestanding sign application asks for a scaled site plan showing existing and proposed signs and the vision clearance triangle at the drive, detail drawings of each sign, lighting details, construction drawings showing the sign is designed for dead load and wind pressure, and a sign regulation affidavit signed by the owner or representative. Overlay district requirements can also apply.
Do you build neighborhood entrance signs on Johns Island?
Yes. Community entrance monuments are one of the largest categories in our portfolio, and Millers Crossing is a Johns Island example. We also build mailbox kiosks to match.
Do island conditions affect sign materials?
Yes. Humidity, salt air, sun and storm season all wear on signs, so substrates, fasteners, coatings and print films should be chosen for a coastal site. A footing designed for wind matters too, which is one reason the county asks for construction drawings.
