Under Cal. Bus. & Prof. Code § 7031, a contractor must be licensed at the time work is performed under a construction contract in order to sue to collect compensation for that work. In Great West Contractors, Inc. v. WSS Ind. Construction, Inc., the California Court of Appeals held that a contractor’s preparatory acts, including drafting shop drawings and ordering materials, were acts performed in furtherance of the contract and subject to the requirements of § 7031. Because the contractor performed the preparatory acts before its license was issued, the contractor had no right to sue for payment. 162 Cal. App. 4th 581, 76 Cal.Rptr.3d 8 (2008).
