Since July 2019, tiny houses and attached apartments are allowed in Montgomery County despite resistance from residents.  In July 2019, the county council voted unanimously in favor of zoning changes that make it easier for residents to create accessory apartments on their property. The council also approved the zoning changes to create more affordable housing units for low-income residents and retirees. The changes eliminated a provision that neighborhoods can only have one accessory unit every 300 or 500 feet, depending on the zone in which it’s located. The changes also removed a ban on tiny homes and other detached apartments on smaller lots, like those often found in Silver Spring and Bethesda.

Opposition to Tiny Houses

Over a thousand Montgomery County residents signed a petition opposing the changes.  Several reasons were given for the opposition, such as a fear that housing prices in the county would fall. One person said at a protest that the new law would allow people to do whatever they want in their backyards.  Others citizens said it will create crowded neighborhoods and increased traffic congestion. Some opposed the bill because they said it would attract low-income residents and lower the cost of housing.  Still others feared that the new regulations would encourage more transient residents who would disrupt the sense of community in their neighborhoods.
