There are two seasons in San Francisco, rainy season and non-rainy season. Buyers should employ a qualified home inspector to examine the entire property for susceptibility to or history of water damage. Particular attention should be given to basements, garages, crawl spaces, and any area below ground level. Buyers should inquire about the homes location in relation to flood zones or running water.
Sellers are advised to note any water intrusion history or known susceptibility on the Real Estate Transfer Disclosure Statement to avoid potential disputes with the buyer down the line.
