The Amenity That
Retains Residents.
SUMN turns your parking structure into a full mobility hub — shared EVs, e-bikes, EV charging, and smart parking managed entirely by our team.
Residents expect mobility. Most properties still offer just parking.
The renter profile has changed dramatically. Your future residents are less likely to own a car, more likely to use shared vehicles, and actively comparing mobility amenities when choosing where to live. Parking alone is no longer enough.
68%
of Gen Z and millennial renters say mobility amenities influence their leasing decision.

per stall is the median cost to build structured parking — capital that rarely generates a return.
Why communities choose SUMN.
From leasing performance to resident satisfaction, SUMN moves the metrics that matter.
Leasing Advantage
Residents choose apartments that offer shared EVs, e-bikes, and premium charging over comparable units. SUMN turns mobility into a leasing differentiator.
Resident Retention
Communities with SUMN see measurably higher renewal rates. Residents who use shared mobility stay — it becomes part of how they live.
Parking Optimization
Shared vehicles reduce the number of private cars residents need. That means fewer parking stalls consumed, more options for shared use, and better parking revenue.
ESG & Sustainability
Every shared EV and e-bike reduces VMT and carbon output. SUMN helps operators hit ESG targets with infrastructure that actually gets used.
Zero Operational Lift
SUMN handles fleet management, maintenance, insurance coordination, and resident support. Your team does not touch the vehicles or chargers.
Revenue Share
Properties can structure SUMN deployments to share in vehicle and charging revenue — turning a cost center into a modest income stream.
