Summary
In Carson's commercial zones, window signage may cover no more than 10 percent of a storefront's window area, on top of the lot's overall sign-area cap.
The total sign area per lot shall not exceed an area in square feet equal to two (2) times the linear feet of lot frontage on a public street or streets. Window signage shall not exceed ten (10) percent of window area. Lot frontage on a freeway shall not be considered in computing this figure. When the total frontage of a lot is less than the square root of the lot's area, said frontage shall be deemed to be equal to the square root of the lot's area for the purpose of determining the permitted sign area.
3. A ground sign in excess of six (6) feet in height shall not be permitted. The distance between ground elevation and the bottom of a ground sign shall not exceed one (1) foot. Not more than one (1) ground sign shall be permitted on a lot. No ground sign shall be erected until written approval is obtained from the City Traffic Engineer. Such signs shall be in conformance with development plans which have been approved pursuant to the Site Plan and Design Review procedure as provided in CMC § 9172.23.
4. A sign may be affixed to a building but shall not project above the height of the building wall or roof fascia.
5. A sign shall not project into an existing or future right-of-way.
6. No "A" frame or "sandwich" sign, or scintillating, flashing or revolving sign shall be permitted.
7. Electronic message center signs are permitted, subject to the following:
(a) Such sign shall be at least one hundred (100) feet from a residential zone.

Full Breakdown
Carson Municipal Code § 9136.7(B)(2) limits window signage to 10 percent of window area for businesses in the CN, CR, CG and CA commercial zones and related mixed-use overlays. That cap sits inside the broader per-lot sign allowance, total sign area equal to twice the lot's linear street frontage, so a heavily glazed storefront can't use window coverage to exceed its overall allotment. All business signs, window or otherwise, must also conform to an approved development plan under the city's Site Plan and Design Review procedure, CMC § 9172.23, before installation.
Violations & Fines
Exceeding the 10 percent window-sign cap is an infraction under CMC § 9136.7(E), punishable per CMC § 1200(b), $100 to $500 in fines depending on repeat offenses within a year.
