A long-vacant property in Arlington Heights could be developed with a mixed-use apartment building, according to plans submitted earlier this week to the City of Los Angeles.

The proposed development, slated for a nearly 15,000-square-foot site at the northeast corner of Washington Boulevard and Norton Avenue, calls for the construction of a four-story building featuring 31 residential units - including three reserved as extremely low-income affordable housing - with ground-floor commercial space and parking.

The project, which is being designed by Khal Khaireddin Architects, would feature central and rear-facing courtyards at the second floor and a common rooftop deck.

The developer, Irwindale-based Heritage Developments, LLC, is seeking Transit Oriented Communities affordable housing incentives, including a height increase and a reduction in required side-yard setbacks.

A few blocks north on Venice Boulevard, developer Schon Tepler Group has announced plans to replace a fourplex with a similar mixed-use project.
