While the exact requirements of a Notice to Owner form vary by state, it typically includes information about a property improvement the sender is currently working on to ensure that he is paid for his services by the owner. State statutes may require such a form be sent within a certain time frame, such as Florida's requirement that the owner is served the notice no later than 45 days after labor begins.
The Notice to Owner form gives the property owner a chance to make sure that the sender is paid. He typically does so by obtaining a "release of lien" from the sender as he makes payments. This allows the owner to catalog different payments made to different contractors for their services and ensures he is not later surprised by a lien against the property from a contractor with whom he is not familiar.
Many contractors consider the Notice to Owner as a necessary part of any work they do, as it simultaneously improves the worker's cash flow, enhances communication between worker and owner, and helps to protect the worker's rights if this becomes necessary.
The Notice to Owner form must typically be formally served to the owner. State requirements for how owners can be served vary. In Florida, owners can be served in person, via certified or registered mail, or by posting the notice at a job site if neither previous option is possible.
