Steps
Confirm the property is within a locally designated historic district or has individual landmark status that triggers design review, separate from the underlying zoning district
Determine whether the historic preservation commission (rather than, or in addition to, the standard zoning/building department) must issue a Certificate of Appropriateness before the sign permit can be issued
Prepare the submittal referencing the Secretary of the Interior's Standards for the Treatment of Historic Properties as the general national framework, plus any local historic-district design guidelines for sign scale, materials, illumination style, and placement
Confirm that zoning (size/number/height) and building code (materials/attachment) requirements still apply on top of the historic commission's appropriateness review — the commission's role is typically limited to design appropriateness, not a substitute for zoning or building compliance
Budget extra review time for a commission hearing/public-meeting cycle, since historic district review is often not a simple staff-level sign-off
Known gotchas
Certificate of Appropriateness review is a separate approval layer from zoning and building permits, not a replacement for either — all three commonly apply to the same sign
Local historic-district sign guidelines (scale, materials, illumination) can be significantly stricter than the base zoning code even where zoning would otherwise allow a larger or brighter sign
Historic commission review usually runs on a public-meeting schedule rather than same-day staff approval — factor that into the project timeline
