Castaic FAQ
Do product displays count toward the window coverage limit?
Yes when they obstruct visibility into the store. Title 22.140.430 measures total visual obstruction including signs, posters, and dense interior displays against the 25 percent window glass area threshold.
Can I run a temporary sale banner in my window?
Yes for up to 30 consecutive days without a permit. Remove the banner within seven days of expiration. Repeated rotating banners that effectively run year-round may trigger permit requirements.
Los Angeles FAQ
Do paper sale signs in my shop window need a permit?
No, temporary non-illuminated paper signs do not require a permit, but combined coverage cannot exceed 25% of the window area facing the street.
Can I install neon behind my window?
Yes, with a sign permit from LADBS. Animated or flashing displays are prohibited outside Sign Districts, and HPOZ areas require additional design review.
