It is illegal to erect or affix a sign in the right-of-way (the area from the curb to the sidewalk,) in the median (the area in the middle of a street,) on trees, public fences, buildings or utility/telephone poles.
A permit is required to erect a sign on private property. A sign permit may be obtained from the Code Services Department.
Garage Sale Signs
One sign is allowed in the seller's immediate yard and another may be placed at the end of the block with the owner's permission. However, signs cannot be placed in medians, on utility poles or in rights-of way.
