We were the subs on a job and they filed a notice of completion on the project feb 14 . the city issued them two permits one for on site and one for offsite work . The contractor is withholding retention from us for some of the offsite work that we clearly have written in our warranty and subcontract exclusion of that scope of work . Since there are two permits how do I find out if that notice of completion was for the entire project or would it only pertain to the permit that has been officially signed off by the inspector . the one permit that has not been signed off is the offsite work which is the scope of work that the contractor is withholding the retention . Trying to see if I am within my legal rights to file a mechanics lien on the project . Any help would be appreciated
