I am a Contractor building a custom home for clients who own the land. Clients are constantly harassing trades while working during working hours. Bringing their children along with several belongings that they leave at the job, expecting my team to be responsible for protecting their things. They are aware we are dealing with delays on exterior locking doors. Can I implement anything now, can I change my contract to state any guidelines in the future on these issues? I don’t know what I can do since they own the land.
