TapeAndFloat.comSubstantial completion
By James Grokman, CEO, TapeAndFloat · Updated 2026-10-28
Substantial completion is the point where work is complete enough for the owner to use the space for its purpose, with only minor punch-list items left. The contract usually defines it, and it is often tied to retainage release and other milestones.
Not legal advice. This is a general explanation for contractors across the U.S. Lien and payment rules differ by state and by contract, and they change. Before you act on a lien, waiver or payment clause, talk to a construction attorney in your state.
Why it matters on a drywall job
- For a drywall sub, your work may be substantially complete well before the project is.
- Knowing how your contract defines it helps you know when to bill retainage.
For one state's rules, see the Texas lien guide for subcontractors. It covers Texas only.
