Spring cleaning; a good curb cleaning, fresh coat of paint, maybe new exterior lighting, or an all out new store front. What is the lifespan of those improvements? Who paid for them the last time we spruced this building; the tenant or the landlord? All of the above are important details when planning building improvements and exterior maintenance. A site assessment provides a snap shot in time of a building and site’s exterior characteristics. Whether the goal is to remove a few cobwebs from the front canopy or to provide a detailed analysis on the lifespan of the asphalt lot, a due diligence site assessment is a must have for the planning of building and site improvements.
