Final answer:
The warranty on paint touch-up typically expires 1 year from the completion of the touch-up work, which might be different from the original work's warranty expiration unless stated otherwise in the contract.
Step-by-step explanation:
The warranty period for touch-up paint work provided by a contractor typically starts from the date the touch-up work is completed. If the original warranty provided by the contractor after Substantial Completion (SC) is for 1 year, any additional work, such as touch-up paint, is generally considered as separate work under the warranty terms.
Therefore, the warranty on the paint touch-up would expire 1 year after the date the touch-up is completed, not necessarily the same date as the warranty of the original work unless stated otherwise in the contract. It's important for the owner to review the contract or warranty agreement to understand the specifics of coverage for touch-up work or extended warranty terms.
