Downtown San Jose has less than 9 million square feet of office space. Three new proposals for downtown San Jose would more than double the amount of office space:

• Google has several parcels in the area around the Diridon Station and SAP Center, and is negotiating with the city for 11 more parcels (See lists at end of story.)

Google is interested in working with the city to bring 8 million-10 million square feet of office space to the area, plus housing, retail and amenities, the amount of which is unspecified. Community groups have started meeting to prioritize requests of the internet giant relative to the massive development.

• The 2.5-acre property owned by Lew Wolff and Phil DiNapoli at 333 W. San Fernando adjacent to Highway 87 is being purchased by Adobe, which announced plans to build a fourth headquarters tower that would add capacity for another 3,000 employees. The company will start to work on design in early 2018.

• Bay Area developers Valley Oak Partners and TMG Partners proposed a 1 million-square-foot campus that stretches along the new Autumn Parkway between San Jose MarketCenter and the arena.

The City Council on May 17, 2016, approved the 850,000-square-foot office development by Trammell Crow and Bentall Kennedy along Guadalupe River at the former San Jose Water Company site near the arena. The mixed-use development could redefine the west side of downtown, with two distinct buildings, a third “connector” structure that allows for larger floor plates to match tech tenant needs, plus generous plaza and commercial spaces fronting 402 W. Santa Clara St.

The City Council granted a construction tax waiver to Trammell Crow for getting its first building permit by spring 2017. The $4 million incentive will happen if the developer completes its project on the SJ Water site by Dec. 31, 2019. However, ground has not yet broken on construction.

Other office buildings with plans submitted includ e:

• Railyard Place by Insight Realty, off Highway 87 and Coleman Avenue, 250,000 square feet.
• River Center by Sobrato, off Julian Street, 190,000 square feet.
• Fourth and Santa Clara Street tower by SJSC Properties across from City Hall, 25,000 square feet of office.

• As of Aug. 29, The Museum Place project at Park and Almaden avenues has a timeline, with the city and developer Insight King Wah LLC agreeing to complete the mixed-use office (263,676 square feet of office), residential, hotel, Tech museum expansion and parking project by 2023.

• The Family Justice Center opened for business Aug. 15, 2016 at Market and St. James streets. The building is 234,000 square feet.

Until the Family Justice Center opened, the last office building completed downtown was the RiverPark II Tower, 318,000 square feet, at 300 Park Ave., in 2010. It is now 85 percent occupied.

The total number of hotel rooms downtown could spike 30 percent if several projects are built out. Khanna Enterprises, which owns the Sheraton Four Points on First Street, wants to construct a 21-story, cantilevered tower over the original 1911 Montgomery Hotel frame. The plans by TCA Architects submitted in May call for an additional 280 guest rooms rising 245 feet, with a roof-top bar, pool and fitness center. The unusual design suggests that the first six floors form the base and floors 7-21 extend slightly over the existing historic structure.

The new part of the future Tribute hotel would face south and be covered in glass. The old 86-room hotel is 187 feet south of its original location. The city’s Redevelopment Agency paid $8.6 million to move the structure in 2000 to make way for the Fairmont Hotel annex. Khanna obtained the property from Joie de Vivre Hotels in 2008.

Also:

• Owner Nimish Patel of the vacant parcel at South Second and Reed streets propose a six-story, 76-room hotel in SoFA;

• A 210-room AC Hotel opened at Santa Clara Street and Highway 87 in early 2017.

• Hotel Clariana also opened in 2017. The 44-room boutique-style hotel was renovated from a former YMCA at Second and Santa Clara streets. Owner RSTP Investments, LLC, plans to add another 60 rooms, plus pool and new lobby on the parking lot it owns adjacent to the hotel between Third and Fourth streets

• The Museum Place property next to The Tech will host a Kimpton Hotel of up to five floors, 184 rooms and 203,207 square feet. The City Council reached agreement with developer Insight King Wah, LLC in August 2017.

• Kade Development has reported intentions to build a hotel at Stockton and Julian near the arena and Google development. Details are not yet available.

If built, the total uptick of about 700 rooms would bring the number of rooms available in downtown San Jose to more than 2,850.

Residential development is still a hot sector with 10,485 homes proposed, under construction or recently completed for 31 different sites downtown – most of them high-rises.

In December 2016, the City Council extended the 50 percent reduction in construction taxes and parkland fees to developers who begin construction before July 2018. The City Council will consider four projects – SJSC Towers, ParkView Towers, North San Pedro Tower and The Graduate for the housing incentive on Oct. 3.
