Lynwood, CA Sign Regulations: Window Signs (2026)

Section 25-70-3(A)(1)(g), Temporary Window Signs, requires that temporary window signs be affixed to the interior of the structure's windows or glass faces, caps their area at 25 percent of the glass face or window, and requires the sign be maintained in good condition at all times. Temporary window signs sit within the article's Restricted Signs section, which also regulates temporary banners under subsection (A)(1)(f): a business can hold only one temporary banner permit per location at a time, up to two permits per calendar year, each valid for a maximum of 60 days, and a banner likewise cannot conceal more than 25 percent of the glass face or window of the building.

Restricted signs, including window signs, must be submitted to the city for review and approval under section 25-70-4: staff-level approval applies to signs that pose no threat to public health, safety, or adjacent property interests, while signs that could affect neighboring properties, such as lighted signs adjacent to residential districts, go to the planning commission for review and possible public hearing. Section 25-70-11 declares any sign placed unlawfully over land owned by a governmental entity, or over a public right of way without an encroachment permit, a public nuisance.

A staff determination on sign approval can be appealed to the planning commission under section 25-70-6, and a planning commission determination can be appealed further to the city council; either appeal can be filed by the sign applicant or by a property owner within 300 feet of the sign.
