Kinyons Addition, recorded in property legals as H.H. Kinyon's Addition, is a small early-platted St. Petersburg subdivision off 4th Street N near 7th Avenue N in ZIP 33701. It sits on the southwest edge of the Historic Old Northeast, the city's first established subdivision, founded in 1911, and a short walk from downtown St. Pete and the waterfront (Old Northeast and St. Petersburg neighborhood guides, 2026).
The plat is laid out in lettered blocks, with parcel legals referencing blocks such as Block A, Block B, and Block C off 4th Street N and 6th and 7th Avenues N. The housing is older St. Petersburg stock, with some parcels along the 4th Street N corridor in commercial or redevelopment use, so the exact block and parcel matter a great deal.
Because this is such an old plat, most parcels carry no mandatory HOA, and the money is made or lost on the parcel, the condition of an older home, and an honest read of its roof, systems, flood exposure, and insurability, not the plat name.
The pitch is location: a walkable position on the edge of the Old Northeast, close to downtown St. Pete's Beach Drive dining, the St. Pete Pier, the museums, and the waterfront parks. The work is reading the parcel, the flood zone, and the condition of an older home before you fall for the address.
