Downtown COASTER Delayed to Late 2026: $33M Convention Center Platform
TL;DR: COASTER Delay Extends Cash Buyer Window
Downtown San Diego's COASTER platform construction has been delayed to late 2026, pushing completion from 2027 to late 2027 or early 2028. The six-month delay extends the pre-development acquisition window for cash buyers targeting properties near the future transit hub between First Avenue and Fifth Avenue along Harbor Drive. With downtown showing 7 months of condo supply at $795,000 median and 68% of luxury buyers paying cash, the delay creates additional opportunity before transit-oriented development premiums materialize.
The North County Transit District (NCTD) has confirmed that construction of downtown San Diego's long-awaited COASTER platform will not begin in spring 2026 as originally planned. The $33 million project now targets a late 2026 construction start, with completion pushed to late 2027 or early 2028.
"It is unlikely that construction will start in spring of 2026, as these utility reviews are critical to the project," said Shawn Donaghy, NCTD chief executive, in September 2026 statements to CBS 8 San Diego.
The 850-foot platform will extend from First Avenue to Fifth Avenue along Harbor Drive, directly across from the San Diego Convention Center and steps from Petco Park. Construction is expected to last approximately 18 months, with notable work along Harbor Drive including removal of a grassy strip and tree relocations.
The fully-funded project will accommodate eight passenger cars and provide direct transit access to the Convention Center, Gaslamp Quarter, East Village, and The Rady Shell at Jacobs Park.

Extended Opportunity Window for Cash Buyers Near Future Transit Hub
The six-month construction delay extends the pre-development acquisition window for cash buyers targeting properties near downtown San Diego's future transit hub. With completion now projected for late 2027 to early 2028 instead of 2027, homeowners considering a cash sale have more time to sell before transit-oriented development premiums materialize.
Downtown San Diego currently shows 350 condos available for sale with approximately 7 months of supply—firmly in balanced-to-buyer's market territory. The median condo price in the 92101 ZIP code hovers near $795,000, with properties taking 70 to 90+ days to sell.
Cash buyers hold significant advantages in this environment. Sixty-eight percent of luxury buyers paid cash in 2026, making them far less sensitive to elevated mortgage rates than financed buyers.
The construction delay also creates motivated seller situations among downtown condo owners who anticipated earlier construction disruption. Properties within walking distance of the future station—particularly in the Convention Center area, East Village, and Harbor Drive corridor between First and Fifth Avenues—represent prime targets for cash acquisition before the 2027-2028 completion drives transit-oriented development demand.
