🏗️ St Pete Double Lot, NT-1, Non-Flood, Two Platted Lots

Vacant double lot totaling 10,306 SF (0.24 ac) on 9th Ave N in the Crestmont subdivision / Disston Heights edge of central St Pete. Legal description confirms two platted lots (Block 11, Lots 10 and 11) – split is by-right, not a variance request. Zoning NT-1, Flood Zone X, non-evacuation. Elevation 45 to 50 ft above sea level. Utilities at street, alley access at rear. One block north of Central Ave, 3 mi to Gulf beaches, 4 mi to downtown St Pete.

Lot Assets:

• Two platted lots of record. Legal description explicitly lists “Block 11, Lots 10 and 11.” This is not a split-requires-variance situation. Each lot can be built separately with a clean subdivision recording, not a Development Review Commission hearing. This is the single most valuable feature of the deal.
• No HOA, no CDD, Flood Zone X. Clean entitlement, no insurance penalty.
• NT-1 zoning with alley access. Alley qualifies the lot for reduced rear setback (6 ft), garage to rear, and preserves clean front elevation.
• 10,306 SF total, 80 ft frontage. Each platted lot is ~40 x 128. NT-1 minimum lot width is 45 ft, so verify exact platted dimensions before close. If the original plat shows each lot at 40 ft, they’re grandfathered as legal nonconforming; if platted at something larger, they meet code.
• High elevation (45 to 50 ft). Disston Heights edge is St Pete’s highest ground. Strongest insurance rates in the city.
• Utilities at street. Water, sewer, electric available. Tap fees only.
• Central location. 1 block off Central Ave. SunRunner BRT, Grand Central District, Tyrone Mall, Pinellas Trail within 5 min.
