The plaintiff landlord leased industrial premises to the defendant tenant, an agro-industrial chemical wholesaler and distributor, for close to ten years. The lease agreement provided that the premises would be used for storage and distribution of chemicals and allied products, and that upon termination the defendant would return the premises in good order "fair wear and tear excepted." The defendant was also obligated to maintain the premises in a clean and sanitary condition, repair interior plumbing, redecorate internal walls when necessary, and replace damaged fittings, fixtures, window panes, door locks and keys. After the defendant vacated the premises, the plaintiff claimed that the defendant had caused considerable damage including: chemical spillage damage to floors (particularly in the "red/pink" and "purple" rooms), damage to electrical power trunking, lights, switches and sockets, damage to plumbing in toilets, broken window panes, damaged locks and keys, and a pungent smell from industrial chemicals. The plaintiff claimed damages totaling US$52,150.78, comprising consultation fees for engineers (US$5,198.05), actual cost of repairs (US$19,145.73), electrical repairs (US$1,043.00), plumbing (US$1,248.00), glass repairs (US$296.00), locks and keys (US$220.00), and lost rental income for five months at US$5,000 per month (US$25,000.00). The defendant denied liability, arguing the damage was normal fair wear and tear given the years of occupation and the nature of products stored, which the lease had expressly acknowledged.
