Do I need a permit for addition or structural alteration in Largo?
Yes. In Florida, addition or structural alteration generally requires a permit, and Largo is no exception.
A building permit is required for any addition and for structural alterations such as removing or altering load-bearing walls, changing the footprint, or altering the roof structure. The Florida Building Code only exempts ordinary minor repairs that do not cut into walls or remove load-bearing supports, so structural work is never exempt. Additions usually trigger zoning review and, in flood areas, elevation requirements.
Florida and local notes for Largo
Structural work is specifically excluded from the HB 803 $7,500 exemption. Signed and sealed engineered plans are commonly required. Additions often trigger setback, lot-coverage, and floodplain review. Pinellas County's own permitting office is the Building and Development Review Services Department, reachable on (727) 464-3888 at https://pinellas.gov/applying-for-a-building-permit/. Its online permit portal is https://aca-prod.accela.com/pinellas/default.aspx. It issues permits for the unincorporated county. If your city does not run its own building department, this is the office that will handle the job. Contractor licensing here is countywide, which is unusual. The Pinellas County Construction Licensing Board, established in 1973, regulates construction and home improvement contractors practicing in Pinellas County including all local municipalities, so whoever you hire needs to be licensed through it no matter which city you are in. Reach it on (727) 582-3100 or pcclb@pinellas.gov, 440 Court St, 1st Floor, Clearwater. State legislation has been changing which specialty trades are licensed locally rather than by the state, so confirm the current license type your trade needs before signing a contract. Largo requires buildings in flood hazard areas that undergo improvements or repairs costing 50 percent or more of market value to meet current flood standards, and CDC 11.7.4 has the Floodplain Administrator compare the combined cost of improvements and repairs to the building's market value. Largo accepts only digitally signed and sealed plans. First review typically takes 10 to 14 business days, resubmittals another 10 to 14, and the city offers no expedited review. Permits may be routed to Building, Planning, Fire, Engineering, and Landscape for review, and plan revisions need a narrative letter from the design professional and cost $25 per page.
