Keegan is leasing space from Aptos developer Joe Appenrodt who last year bought the 43-acre Aviza site, a gated property with buildings containing 200,000 square.
Keegan has neighbors at the complex, including the Sants Cruz Derby Girls, a vitamin company, a solar company and a hot rod restoration company.
Three times, developers were in contract to buy the property to build homes there but each time they backed out.
