Overview
A 7-story mid-rise building in the Gaslamp Quarter
At Gaslamp City Square, the Gaslamp’s restaurants and nightlife start at the front door. Gaslamp City Square is a 7-story condominium community at 450 J Street and 445 Island Avenue, in the heart of the Gaslamp Quarter in Downtown San Diego’s 92101 zip code. Completed in 2004, its 223 homes sit right in the middle of the Gaslamp Quarter’s dining and nightlife.
Gaslamp City Square gives you the best of both worlds: an address in San Diego’s most famous entertainment district, and a calm, resort-style retreat once you’re through the gate. Residents share a pool, spa, fitness center and BBQ area, gated security looks after the building, and pets are welcome under the HOA’s rules. With 223 homes, it offers plenty of choice without the scale of a high-rise.
Step outside and the historic Quarter’s restaurants, rooftop bars and theaters are at street level, with Petco Park, the Convention Center and the waterfront only a few blocks away. For buyers who want a relaxed home base in one of downtown’s best-connected neighborhoods, Gaslamp City Square is worth a close look.
