Ordinary Homes of the United States

Time period: 1890s-1920s, 1960s-1980s, 2020s to present day Location: Suburbs nationwide The classic US fourplex is a 2-story building with four apartments: two upstairs, two downstairs. First becoming popular when streetcars (also known as trolleys or trams) made suburbs possible, the fourplex offers choice for households who want to get out of the crowded city but can't afford or don't need a standalone house. Cross section of a fourplex . Before streetcars, city dwellers lived within walking distance of the city center. Few people could afford horses, so walking speed limited the physical size of cities. Adults walk at 2-3 miles per hour, which meant the largest ancient and medieval cities were just a couple miles wide. When population grew, cities would grow upwards, replacing houses with townhouses and tenements, 3-7 stories tall, built right next to each other with walls touching. Streetcars were invented in 1887 and could go much faster. Even with time waiting at traffi...

Time period: 2010s to present Location: Suburbs and rural areas The modern farmhouse has its roots in the late 1980s, starting out as a down-to-earth interior design trend for people tired of or turned off by the shiny glitz of 1980s conspicuous consumption. That said, the farmhouse is also a a status symbol. The gilded penthouse condo stands for financial and industrial wealth, the farmhouse stands for wealth from land ownership. Farmhouse style is based on the farm owner's house, rather than the shacks and labor camps of tenant farmers and migrant farmworkers.

  Time period: 20th century to present day Location: Suburbs In places that allow them, Accessory Dwelling Units are a way to have more than one home on a lot that is zoned only for one regular full-size home. ADUs are a second, smaller home (typically studio, 1-bedroom, or 2-bedroom) on the same property as a full size house. They're also called accessory apartments, secondary units, in-law suites, and granny flats. Hawaii calls them Ohana dwellings. In zoning and building codes, accessory uses are minor uses that are allowed as part of a larger project, even if the zoning or occupancy type does not normally allow it. An example of an accessory use is the manager's office of an apartment building, which is allowed in a residential zone even though it's an office use. ADU's are a similar regulatory reform to allow two homes on a single family lot, without changing it to duplex zoning. Examples of types of ADUs. Each type of ADU has advantages and disadvantages.

  Time period: 2020s and onwards Location: California California state law allows a single-family home to become three homes: 1. The main house, which can be whatever size allowed by zoning 2.  An attached or detached Accessory Dwelling Unit (ADU). Can be any size, cities must allow at least 800 square feet (enough for a 2-bedroom, 3 if you squeeze it) 3. An attached Junior Accessory Dwelling Unit (JADU), of up to 500 square feet.

While California state law as of 2022 also allows up to 4 homes ( double duplex ) using Senate Bill 9, the ADU+JADU route is currently more popular, for two reasons: First, fees and code requirements are lower for ADUs. Second, many cities have put up barriers to using SB9 - this is in the process of being corrected by cleanup ...
