Segment Reporting [Abstract] |
Segment Reporting Disclosure [Text Block] | Information on Segments We operate in two segments: traditional home building and urban infill. We build and sell detached and attached homes in luxury residential communities located in affluent suburban markets that cater to move-up, empty-nester, active-adult, age-qualified, and second-home buyers in the United States (“Traditional Home Building”). We also build and sell homes in urban infill markets through City Living.

The states comprising each geographic segment are as follows: North: Connecticut, Illinois, Massachusetts, Michigan, Minnesota, New Jersey, and New York Mid-Atlantic: Delaware, Maryland, Pennsylvania, and Virginia South: Florida, North Carolina, and Texas West: Arizona, Colorado, Idaho, Nevada, and Washington California: California Revenue and income (loss) before income taxes for each of our segments, for the periods indicated, were as follows (amounts in thousands):
