Onelife Fitness may have found a way into the Mosaic District.

According to a zoning verification letter submitted this week with Fairfax County on Onelife’s behalf, the fitness center plans a facility at 2910 District Ave. that is larger than 30,000 square feet and “includes pool(s).” 

Onelife Fitness declined to comment at this time. It is unclear if a lease has been signed.

The first floor of 2910 District Ave. is consumed by various retailers while the upper three levels, totaling roughly 72,000 square feet, are all leased by Custom Ink — but only for a little longer.

Custom Ink, the swag producer, announced in September 2022 it would exit its administrative offices in favor of a fully remote operation. It has been trying to sublease the space, which sits directly across the street from Target, ever since. The Custom Ink lease expires on March 31, so Onelife would likely sign a fresh lease with Edens, Mosaic’s developer and owner, as opposed to a sublease, according to a person familiar with the property.

JLL is managing the sublease effort on Custom Ink’s behalf, while Avison Young leases the office for Edens at Mosaic. Neither brokerage responded to a request for comment on the prospective Onelife deal. Edens representatives did not respond to a request for comment.

At 30,000-plus square feet, the fitness center would require at least two of the three floors. Several permits have been filed for the Custom Ink headquarters since September — none identify Onelife — including one that would remove the staircase between the second, third and fourth floors to prepare for a future tenant or tenants.

There is no fitness center at Mosaic District, but several major players are found nearby — LA Fitness backs right up to Mosaic on Strawberry Lane, while Gold’s Gym sits barely half a mile to the south at Fairfax Plaza.

Onelife Fitness was acquired in October by 26North Partners LP, the private equity firm founded by Washington Commanders owner Josh Harris. The fitness chain manages 61 clubs with some 400,000 members, roughly half of which are found in the D.C.-Baltimore regions. Southeastern Virginia and Georgia are its next largest markets, and the company is in major expansion mode under CEO Ori Gorfine.
