The compatibility determination begins by first evaluatingthe he block face to determine if a uniform architectoral style is present aniong the single-family homes and/or if prevalent styles exist in the treatment of garagre placement,roof design,primary entries, and windows. The block face includes all properfies facing one side of a street in a block. For short blocks with few examples, relevant homes for evaluation may also include properties adjacent to the site that are not on the block face.
