If you are weighing home additions work in Marco Island, FL, the right number depends on the scope, the materials you choose, and the condition of what is there now. Below is what most local homeowners pay, what moves the price, and how we handle the job from inspection through cleanup.
Marco Island was master planned by the Deltona Corporation in the 1960s, and its waterfront grid of canal homes and condo towers largely dates from the 1970s through the 1990s. Remodels here lean heavily toward opening up older floor plans, moving kitchens toward the water view, and refreshing condos between seasons. Island logistics and coastal permitting reward tight planning of deliveries and trade sequencing. The island runs its own building services department, and its mix of stilt construction and canal frontage means structural and elevation questions come up more often than on the mainland. Salt air is a real factor in material selection too, from fasteners and hardware to exterior finishes.
Census figures put the median Marco Island home at about 38 years old, built around 1988. The market covers about 18,436 homes, and the median value sits near $866,200. Census data counts about 50 percent of Marco Island homes as seasonal residences, which is why so many projects here run while the owner is out of town. Those numbers are the starting point for how we plan home additions projects in Marco Island. Figures are U.S. Census Bureau American Community Survey estimates.
