La Mora Senior Apartments is the first modular, multifamily development in the United States to achieve Passive House Institute U.S. (PHIUS) certification. The 60-unit project offers affordable, energy-efficient homes for older adults in a market where demand significantly outpaces supply. Built on a long-vacant site, it allows seniors to remain in their community in safe, comfortable housing.
La Mora shows that modular construction and Passive House standards can be combined to deliver high-quality, affordable housing. Despite technical complexity, the project remained cost-conscious and met critical performance goals. It offers a replicable model for communities seeking energy-efficient housing solutions for older adults, especially in high-demand markets.

The U-shaped building form responds to the site’s slope and creates a quiet, landscaped courtyard. Along the street, alternating bays reflect the rhythm of neighboring townhomes. Generous corner windows bring daylight and views into units, and layered landscaping softens the building edges while screening parking areas. A light-filled resident lounge supports casual gathering and community. The light-filled lobby offers residents a comfortable space to relax, socialize, or watch for rides and deliveries. Resident mailboxes open to the welcoming lobby, encouraging casual interaction.
A ground-floor multipurpose room with a separate entrance is shared with residents from the broader Housing Authority network, expanding the building’s benefit beyond those who live onsite. Double-height space is made possible through modular design. The roof deck includes planters for resident use and a retractable canopy. This alternative outdoor amenity supports resident comfort and seasonal use.
Each apartment features stone countertops, luxury vinyl plank flooring, in-unit laundry, and individual HVAC systems. Corner apartments feature oversized windows that maximize daylight and the neighborhood views. Triple-pane windows, continuous insulation, and airtightness levels of 0.06 CFM/SF reduce energy use and improve indoor comfort.
