Echo (P) leased premises on the downstairs floor of building. When the Bank (D) purchased the building, it assumed the lease and became P's landlord. D undertook to remodel the building and this created noise, dirt and interruptions in the electrical service and made the rear parking lot inaccessible. D eventually changed locks on the doors that P's employees were forced to use because of the construction and as such P's employees were no longer able to get in or out of the building through certain doors after business hours. P's only access was through the rear door, and P presented evidence that access was obstructed and difficult at times. P sued D for constructive eviction, breach of the implied covenant of quiet enjoyment and breach of the lease. The trial court gave the verdict to D and P appealed.
