Tenant improvements to a piece of property become the property of the land owner.
Not always. Plus that is negotiable. Plus once they become part of the permanent structure YOU are responsible for maintaining it. If a tenant wants/needs improvements, usually the property owner either shares in the cost, or offers a reduction in rent to the tenant to offset the cost of the needed improvement or adjustment to the property in order for it to be suitable for him to conduct his business in. The property owner may even offer (gasp) free rent for a period. Most commercial property owners are very flexible in that regard, because an empty property generates ZERO revenue. Ther are pricks in the business however. Those properties tend to stand out as run down eyesores that are vacant half the time. They become crack houses, places where vagrants dwell, fire hazards, and an overall burden to the city.(the taxpayer) Are you one of those? For some reason, it wouldn't suprize me.
