Most of our commercial work runs through three corridors. Downtown St. Petersburg — Central Avenue, 1st Avenue North, Mirror Lake — is the highest-density corridor for storefronts, restaurants, and tenant buildouts; many of the buildings here date from the 1920s through the 1960s and trigger ADA Title III upgrades on any permit. Grand Central District and the EDGE District are the highest-growth commercial corridors, with arts-district retail and restaurant tenants moving into older warehouse and mixed-use stock.
Gateway and Carillon Park are where the office and professional-services work lives — newer construction, larger floor plates, and lower historic-context overhead. Warehouse Arts District and the Skyway Marina District round out the south-of-downtown corridors where adaptive-reuse buildouts on pre-1950 commercial stock are common.
Some of these corridors fall inside FEMA AE flood zones — commercial buildings in St. Pete’s FEMA flood zones face the same 50% substantial-improvement rule that drives residential elevation decisions. And where commercial parcels sit in a Local Historic District — most commonly in Old Northeast and Granada Terrace — exterior changes trigger Certificate of Appropriateness review, the same as a historic commercial building renovation.
