Plaza on Harbour Island — Condos for Sale & Building Guide

What is Plaza on Harbour Island? Plaza on Harbour Island is a 20-story luxury condominium at 450 Knights Run Avenue on Tampa's Harbour Island, directly adjacent to downtown and Water Street Tampa. Completed in 2007, the building offers approximately 141 residences — including high-rise condos, street-level townhomes, and casitas along the Palm Court — with views of Hillsborough Bay, the Tampa skyline, and the Garrison Channel.

The tower has established itself as one of the signature residential addresses on Harbour Island, combining a walkable waterfront location with full-service amenities and a range of floor plan options.

Unit Types & Floor Plans

Plaza on Harbour Island offers one- to four-bedroom floor plans ranging from approximately 1,100 square feet to over 4,400 square feet. Two-bedroom units typically run close to 2,000 square feet, while three-bedroom layouts start above 3,000 square feet. Most units feature open floor plans, floor-to-ceiling glass, and private terraces.

Beyond the tower residences, the building includes street-level townhomes and casitas along the Palm Court — a landscaped interior courtyard. These ground-level units offer a different living experience with private entries and a more residential feel.

The tower's positioning on Harbour Island provides water views from multiple exposures. West- and south-facing units look out over Hillsborough Bay and the Bayshore Boulevard corridor. North-facing units offer direct views of the downtown Tampa skyline and Water Street. East-facing units overlook the Garrison Channel and Harbour Island's marina areas.

Upper-floor units — particularly those on floors 15 and above — offer the broadest panoramas. However, even mid-level units benefit from the building's waterfront location, where surrounding structures don't obstruct sight lines.

Harbour Island sits directly across the Garrison Channel from downtown Tampa and Water Street Tampa. From Plaza, residents can walk to Water Street's restaurants, Sparkman Wharf, and the Tampa Riverwalk within minutes. The Tampa Convention Center, Amalie Arena, and the Florida Aquarium are all within a short walk or bike ride.

For commuters, downtown Tampa offices are less than a mile away. Tampa International Airport is approximately 15 minutes west. The Selmon Expressway on-ramp is nearby, providing direct access to Brandon and points east. Harbour Island also has its own waterfront parks and a pedestrian-friendly streetscape.

A few practical considerations for buyers evaluating Plaza on Harbour Island:

- HOA fees cover amenities, insurance, water/sewer, exterior maintenance, and common area upkeep. Fees vary by unit size and change annually — always request the most recent budget and reserve study before making an offer.
- The building has historically permitted pets with a policy allowing up to two pets with a weight limit around 100 pounds. Breed restrictions may apply. Verify the current pet policy with the association, as rules can change by board vote.
- Leasing policies are governed by the condominium documents and may include minimum lease terms and approval requirements. Confirm current rental restrictions before purchasing if you plan to lease the unit.
- Each unit is designated 1, 2, or 3 garage parking spaces depending on the floor plan. Guest parking is also available.
- Plaza was completed in 2007, which means some original-era finishes may appear in unrenovated units. Many owners have upgraded kitchens, bathrooms, and flooring — the level of renovation varies significantly unit to unit.
- Insurance in a high-rise condo works differently than single-family. The association carries a master policy for the building structure; individual owners need an HO-6 policy for interior contents, improvements, and personal liability. Your insurance agent can walk you through the specifics.
