The temporary sale/lease for construction company ads for buildings under actual construction are exempt as long as they are not above the district height limit or 100ft, whichever is lower. It is possible that the signage may be illegal. The San Francisco Planning Department is aware of this issue and is currently investigating this matter.

The Planning Department inspected this property and contacted the owners to remove the sign. The case was closed on 10/9/2013. For further information, please contact Jon Purvis at the Planning Department (415) 558-6354.

Thanks for fixing this issue!
