Summary

Fullerton's sign code makes an exception inside its own exemption list: a sign inside a building is normally exempt from the chapter's design standards, but § 15.49.030(A)(5) pulls that exemption back the moment the sign is "painted on an exterior window or door, or so placed as to be viewed primarily from outside a building."

(5) Signs located inside a building, except where the sign is painted on an exterior window or door, or so placed as to be viewed primarily from outside a building;

Full Breakdown

030(A) exempts several sign categories from the chapter's design standards outright, including name plates under two square feet and nonprofit event signs. 020's design standards the same as a permanent wall sign. 060(A)(1)(b), even though it must still fit within the area allowance.

Violations & Fines

A window or door sign that exceeds the BUILDING SIGN area allowance in Table 15.49.020, or an interior display aimed at the sidewalk that ignores the § 15.49.030(A)(5) carve-out, is a sign "erected, constructed or placed in violation of the provisions of this chapter" and is declared a public nuisance under § 15.49.010(B), enforceable through the Chapter 6.01 nuisance-abatement process referenced in § 15.49.110.

Frequently Asked Questions

Can I paint a sign on my storefront window without a permit?
Yes, painting a sign on a window or door does not require a sign permit under § 15.49.060(A)(1)(b). It still has to fit within the BUILDING SIGN size allowance in Table 15.49.020 because § 15.49.030(A)(5) removes the interior-sign exemption once the sign is painted on an exterior window.
Are all indoor signs exempt from Fullerton's sign rules?
No. Section 15.49.030(A)(5) exempts signs located inside a building only if they are not painted on an exterior window or door and are not positioned to be viewed primarily from outside. A sign meeting either exception has to comply with the chapter's design standards.
How much window signage is my storefront allowed?
Under the BUILDING SIGN standard in Table 15.49.020, the wall with your main entrance gets three square feet of sign area per lineal foot of building frontage, and other building faces get one square foot per lineal foot, an allowance that applies whether the sign is mounted or painted on glass.
