Sign Plan & Submission Notes for Princeton
- A sign permit is required for all signs unless they qualify as exempt; applications are filed with the zoning officer and must meet dimensional standards in Tables A (freestanding) and B (facade).
- Each non‑exempt sign is classified by the zoning officer as As‑of‑Right, Restricted, or Design Review.
- As‑of‑Right signs that meet size, height, location, and illumination standards and contain no prohibited features receive a permit; site plan review is not required.
- Restricted signs that meet standards receive a permit without site plan review, but content is limited to business name, address, brief description, and an optional logo up to 10% of sign area, with a maximum of three colors.
- Design Review signs (including all signs for conditional uses) are reviewed against specified design criteria; unless waived, concept plans and sample field mock‑ups must accompany the application; the review and approval process follows the procedure applicable to minor site plan approval.
- In the SC Shopping Center District, signs must be consistent with the district’s general signage plan; if the zoning officer finds a proposed sign inconsistent, the application is referred to the Planning Board or its subcommittee, which may approve only if the sign is consistent with the plan and satisfies the Design Review criteria.
- For Design Review signs, the Planning Board or its subcommittee may permit both a freestanding and a facade sign on the same frontage when conditions such as building proximity to the street, building size, visibility, or traffic speed warrant both.
