Some RestrictionsHoliday Displays
Portland's Land Use Code regulates "signs" as defined in Chapter 14; private, non-commercial holiday lights, wreaths, inflatables, and seasonal yard decorations are not signs and do not require a permit. State temporary-sign rules (23 M.R.S. §1913-A) and on-premises rules (23 M.R.S. §1914) supply the outer limits; Portland's general nuisance and historic-district rules can still reach displays that block sightlines or violate the Munjoy Hill / Old Port historic standards.
