Full Breakdown
Hesperia Municipal Code § 16.36.040(M) exempts window signs, whether painted directly on the glass or hung as banners and posters inside, from the sign chapter's permit requirements citywide. Multifamily developments carry one added constraint: § 16.36.070(C), governing apartment, condominium, and mobile home park signage, caps window signs at twenty percent of the available window area, but only on the development's community or office buildings, not individual dwelling units. No separate site sign plan is needed unless the property wants signage beyond what this section allows.
Violations & Fines
Window signs generally need no permit, so there's no standalone violation; exceeding the 20% cap on a multifamily community building's windows makes the excess a public nuisance subject to abatement under § 16.36.030(K).
