Payment Timing

Hello, A client is holding off payments for the following reasons: 1) He wants us to finish a small list of final items prior to partly paying an invoice (not the final invoice) 2) He wants us to replace some tile in his bathroom floor that has some damage. We have offer to replace the tile, but he doesn't want to do this until after the holidays (in at least 30 more days) 3) He has moved in and wants to spend the holidays and then send us an additional punch list after the holidays 4) He wants to add items that were not in his scope of work and he feels that because his project was expensive we should work on these items for free 5) He says he may, next year, want to tear his balcony that was fully finished 8 months ago and instead of having drains make a slope for water to drain to the side of the balcony. 6) He wants a licensed electrician and plumber to sign off on his job. We did not use a licensed plumber, but everything in his house is working properly. We did not use permits for his project. My question is, are any of the above legal reasons for him to not pay us?
