The aim of this study is to determine the form of probabilistic function of fire-spread from a burning building to neighborhood. Firstly, some empirical concepts are made clear from a view point of probability, and formulated as hypotheses which are fundamentals of our mathematical considerations. Secondly, the probability of fire spread from burning building to neighborhood is determined as a function of time and a coefficient which is defined by height and distance between burning and ignited buildings by only mathematical derivation from the above hypotheses. And the final fire spread probability function which is defined as time become to infinity is determined. Thirdly, the parameter of final spread probability function is estimated by using a set of data on 1443 actual fires which are happened in Tokyo metropolitan area.
