The ADU Exchange
National Summit
The annual gathering where housing policy meets homeowner action. Builders, policymakers, architects, and investors — all under one roof.
Four Enormous Markets.
One Intersection.
The ADU Exchange sits at the convergence of four massive, accelerating forces reshaping American housing. Alone, each is a trillion-dollar shift. Together, they're unstoppable.
The Housing Shortage
America faces its worst housing deficit since WWII — 3.8 million units short by federal estimates.
New construction can't keep pace. ADUs add density without rezoning, new infrastructure, or political battles.
Every ADU built on an existing lot is a home created at zero land cost — the single largest expense in housing development.
The Aging Population
By 2030, every Baby Boomer will be 65+. The demand for aging-in-place solutions is a demographic certainty.
ADUs allow seniors to downsize into their backyard while family moves into the main home — or vice versa.
Universal design ADUs are the most cost-effective alternative to assisted living, which averages $4,500/month.
Real Estate Investing
ADUs deliver 8–14% returns — comparable to or better than most traditional real estate investments.
Zero land acquisition cost means every dollar goes into the asset. That's a structural advantage no other RE class offers.
Monthly rental income of $1,200–$3,400 transforms a single-family home into a cash-flowing asset — often covering the entire mortgage.
Multigenerational Housing
Nearly 1 in 5 Americans now live in a multigenerational household — a figure that's quadrupled since 1971.
ADUs offer privacy with proximity — the ideal arrangement for adult children, aging parents, or returning family members.
Cultural shifts, economic pressure, and childcare needs are making multigenerational living the new normal, not the exception.
Not a directory.
The infrastructure of an entire economy.

needs a center.
