This article argues that commercial practices, social relations, and moral obligations in downtown Port-au-Prince shape and are shaped by the vernacular buildings in which they take place. Women living in, and working from, shotgun houses-a structure with a small street facade that allows for both private and commercial life-use these houses to build moral economies woven around familial solidarity and egalitarian relations. Working in houses that formerly belonged to Haitian black middle classes implies inheritance of respectability values based around home caretaking, religious life, and intimacy. In their economic inventiveness, women who do not have access to formal employment mobilize the power and politics of these houses in a distinctive mode of work and entrepreneurship. Houses and acts of commerce, together, form a particular kind of Haitian respectability for women that offers visibility, social networking, and risk adversity.

The buildings erected along this artery range from quake-shattered cinder block commercial structures to wooden houses, brand-new funeral homes, and apartment buildings of all shapes and colors. From sunup to sundown, hawkers crisscross the neighborhood, navigating between the more permanent sidewalk vending stands and the constant traffic that animates this busy administrative and commercial part of Port-au-Prince.Oftentimes, unoccupied sidewalk space indicates the entrance of a restaurant or, more commonly, a ti komès (small business) where economic activities occur around a house or in the front room of a residence. The vast majority of these houses are shotgun houses-structures with a small street facade and rooms that recede in the back in a trainlike fashion. These home businesses are run by women merchants with little financial capital who efficiently navigate a commercial arena where they have historically been "peze s...
