1 WORKING AT HOME IS A FACT OFENTERPRISE HOUSINGLIFE

More and more Americans are working athome, and San Francisco is leading the way.In 2004, the home was the primary or full-time work place for nearly30,000 San Franciscans or 8% of the city’s workforce, many of whomare self-employed individuals operating their own businesses.1 Thisfigure is double the national average and growing faster locally thanit is nationally.2The national increase in home-based work is particularly noteworthy since it reverses the decline seen in the mid-20th century whenpeople migrated from farm-based work to urban employment, andhome-based professionals joined group practices and corporations.3Some of the obvious factors behind this national increaseare corporate downsizing and commuting challenges. The changingcomposition of U.S. households and the economic pressures on lowincome families to make ends meet certainly contribute. As do newtechnologies that support geographically dispersed businesses andmake working from home feasible and attractive.1

Economist Henry Beale, author of a2004 report on home-based business for the Small BusinessAdministration, describes the central role played by the homein supporting entrepreneurial ventures:5“Home-based businesses, which make up roughly half of all U.S.businesses, are of particular interest because of their potentialas a wellspring of economic activity.

2 ENTERPRISE HOUSINGANOVERVIEW

E N T E R P R I S E H O U S I N G REFERS TO:The use of a residence to generate income from a homebased business or through work done for another.We prefer this term to the alternatives of live-work, work-live,mixed-use housing, or hybrid housing, because it emphasizes thefirst use—supporting businesses operated from home. Consistentwith this emphasis, the discussion throughout is framed in termsof home-based entreprenuers and their businesses, although itfrequently applies to all home-based workers.Conceptually, Enterprise Housing ranges from the mostinformal live-work situation, such as the conversion of a bedroomcorner into a temporary office, to the most formalized and highlystructured program, such as the large-scale, planned live-workcommunity under long-term development in East Clayton nearVancouver, Canada. 17

a.b.LOCAL EXAMPLESThe Bay Area hosts many instances of multi-unit/multi-familyEnterprise Housing. Some of the more well known are: ProjectArtaud, an artists’ live-work community established in theMission District in 1971; ClockTower Lofts, a residential-officecomplex on Rincon Hill renovated in 1992; Jingletown Homes,a complex of live-work units built in Oakland in 1996; andAdeline Lofts, an affordable housing project and businessincubator in Berkeley completed in 2002.Single-unit Enterprise Housing includes offices, studios,ENTERPRISE HOUSINGworkshops, and retail spaces located in or attached to a home,8as found in San Francisco’s Langton Street community, an enclaveof mostly single-unit Enterprise Housing residences in SOMAthat has existed largely unnoticed for decades, evolving slowlyover time.a.b.c.d.PROJECT ARTAUD SAN FRANCISCO, CACLOCKTOWER LOFTS SAN FRANCISCO, CAJINGLETOWN HOMES OAKLAND, CAADELINE LOFTS BERKELEY, CA
