The $250 million project, proposed by San Diego-based developer J Street Space, is a slight pivot from earlier plans to convert the 25-story Tower 180 building on Broadway into a combination of residential and hotel uses. The cost of that plan was originally estimated at $140 million.<\/p>\n
While office-to-residential conversions are becoming more appealing to developers given the high office vacancy rates in many downtowns and the need for additional housing, J Street is bucking that trend.<\/p>\n
Its now revised plan calls for a dual-branded hotel, composed of a 371-room Hyatt Place and a 189-room Hyatt House. While the rooms are different in size and function within the two brands \u2014 with the Hyatt House geared more toward extended-stay travelers \u2014 they will be intermingled within both the tower building and an adjacent eight-story annex.<\/p>\n

Topping off the high-rise will be an upscale rooftop bar and lounge that will be known as the Lurline Cocktail Club, which will showcase 360-degree views of San Diego\u2019s skyline, bay and ocean.<\/p>\n
J Street acquired the office complex in late 2023 for $61 million, according to property records, just a few years after the skyscraper got a major facelift. It\u2019s partly that renovation, in concert with San Diego\u2019s strong hospitality market, that gives J Street the confidence to proceed with a hotel conversion, its founder says.<\/p>\n
\u201cTower 180 has unique advantages that make the economics work \u2014 the building\u2019s infrastructure was already updated in 2020, it\u2019s fully vacant, and it is part of a mixed-use development,\u201d J Street CEO Saj Hansji said in an email to the Union-Tribune. \u201cAs we\u2019ve continued to study the building and the market, we determined that a hotel concept would be the highest and best use for this property. This approach allows us to maximize the building\u2019s unique attributes and better serve the strong demand we\u2019re seeing in San Diego\u2019s hospitality market.\u201d<\/p>\n
Hotel real estate broker Alan Reay of Atlas Hospitality said he knows of no other office building in California that has been converted into a hotel. That\u2019s because developers and property owners have told him the financials don\u2019t pencil out.<\/p>\n
\u201cA lot of the offices have internal spaces that don\u2019t have windows, and then you have the cost of putting in individual bathrooms, and just the layout of the floor plans have not worked out,\u201d Reay said. \u201cDevelopers say it\u2019s more economical to build from scratch or knock down the building rather than convert it. And they say they can sell those apartments for a lot higher than what they can get for hotel rooms.<\/p>\n
\u201cOn top of that, we\u2019re seeing so many projects being put on hold because the cost of construction has really increased.\u201d<\/p>\n
The project cost for Tower 180 has grown considerably from the original estimate, which Hansji attributes to the redevelopment\u2019s expanded scope and density, as well as \u201cpremium amenities like the Lurline rooftop venue, that will make this an exceptional hospitality destination for downtown San Diego.\u201d<\/p>\n
As for financing, Hansji says J Street has solid relationships with its capital partners, who he does not name, adding that \u201cthe unique nature of this conversion, combined with the building\u2019s existing infrastructure and our team\u2019s track record, has positioned us well in the current financing environment.\u201d<\/p>\n
As uncommon as office-to-hotel conversions are in California, it\u2019s not surprising to see J Street undertaking the Tower 180 project, says Joshua Ohl, director of market analytics at CoStar.<\/p>\n
\u201cLast year, over 1,900 market-rate apartments opened in downtown, pushing vacancy into double digits, while we\u2019ve added few hotel rooms there in recent years,\u201d he said. \u201cNot having seen the interior layout, the full hospitality conversion likely just made more sense from a financial standpoint, even at that price.\u201d<\/p>\n

The design for the dual-branded hotel calls for a lobby lounge and market on the ground floor, a breakfast bar with an additional overflow lounge on the second floor, and more than 12,000 square feet of meeting space across the ninth and tenth floors. There is no separate restaurant, nor a pool, although one was originally considered for the rooftop.<\/p>\n
Current ground-floor retail tenants, among them Mendocino Farms, Blue Bottle Coffee and Anytime Fitness, will remain, the developer said.<\/p>\n
San Diego-based architectural firm Delawie has had to work within certain design parameters dictated by Hyatt, but does have the freedom to imbue the design with a San Diego feel, said Delawie associate Logan Parmele.<\/p>\n
\u201cWe\u2019re pulling in colors and textures you\u2019d experience in more urban areas, so there are some rust, reddish colors and light steel blues that you\u2019d see as you travel around San Diego, like the red brick buildings in downtown, and soft sky blue colors,\u201d Parmele said. \u201cWe\u2019re also really opening up the ground floor lobby and exposing some of the structural steel there and on the second-floor lounge.\u201d<\/p>\n
The tower on 180 Broadway was originally built in 1963 as the U.S. National Bank Building, and the annex was added in 1973.<\/p>\n
