I'm a prime contractor who has finished home repairs through a city subsidized program. For this program, we provide the estimates and the homeowner signs everything contractually with a contract with the City. We then sign the same contract. The homeowner paid their share but the City will not pay their share until the Homeowner signs off that all work has been completed. The Homeowner is not satisfied due to a desired feature of the work that was not featured in the contract signed with the City, but had verbally been indicated. We have attempted to rectify the problem but their demands are unreasonable. The City says they do not get involved in disputes and will not pay out any money until the Homeowner signs. Given that we've completed the work in the contract with the City do we have any claim to make against either the Homeowner or City?
