5 Reasons Pittsburghers Should Care About ADUs

Pittsburgh faces a housing shortage of more than 10,000 units. Families are struggling to find affordable, flexible living options that work for people of all ages. That’s why AARP Pennsylvania recently brought together residents, experts, and local leaders for an interactive event on Accessory Dwelling Units (ADUs).

From trivia games to community-generated sketches of what ADUs could look like, the event was a lively conversation about how these small homes can have a big impact on Pittsburgh.

Here are the five key reasons ADUs matter for our city and why now is the time to act.

ADUs are small homes or apartments built on the same property as a larger house. They can be basement apartments, converted garages, or backyard cottages. Communities have called them guest houses or in-law suites for years.

For families, ADUs mean flexibility: a place for parents, adult children, or long-term rental income. In fact, 64% of adults 50+ say they would consider moving into an ADU to live closer to someone they love.

At our event, residents shared personal stories, including one local resident whose experience living in an ADU helped her save up to buy a house.

ADUs allow older adults to age in place, near loved ones, while still maintaining independence. They could also house caregivers like family members, nurses, or home aides.

61% of adults 50+ say they would consider moving to an ADU if they needed help with everyday activities.

Several participants explained how ADUs are about dignity: creating spaces where care can be provided without giving up independence.

Pittsburgh needs affordable housing options and ADUs are part of the solution.

54% of adults 50+ say they would consider moving into an ADU to lower their housing costs.

Residents at our event spoke candidly about the challenge of high and rising rent and how ADUs could make it possible to stay in the neighborhoods they love.

ADUs aren’t new. Many Pittsburghers have lived in one without realizing it.

From basement apartments to in-law suites, ADUs already exist across the city. But outdated zoning rules often make them difficult — or even illegal — to build today.

Changing zoning codes would make it easier for families to create ADUs legally and safely.

Public support for ADUs is strong. Nearly 80% of Pittsburgh voters age 50+ support zoning changes that would allow ADUs in more neighborhoods.

At the event, Pittsburgh City Councilperson Deb Gross highlighted how ADUs could help address the city’s housing shortage while supporting multigenerational families and caregivers.

AARP Pennsylvania is working with residents, policymakers, and community partners to update zoning rules and expand housing choices. With strong community support and clear benefits, now is the time to make ADUs a reality for Pittsburgh.
