Room additions, garages, enclosed porches, second stories, and other expansions to one-family and two-family homes require the County residential addition path when the property is in unincorporated Pinellas or a County-served partner city. Preliminary feasibility starts with the parcel's zoning district and dimensional standards, then the survey and proposed footprint. The site plan must account for property lines, setbacks, easements, floodplain requirements, utilities or septic, drainage, trees and habitat, and other site constraints. Structural feasibility for a second story is an engineering question involving the existing foundation, walls, connections, and continuous load path. Heated living area from the Property Appraiser should not be used as a substitute for footprint, impervious surface, or zoning calculations.
