Aging-in-Place Remodeling in Miami, FL: Homes, Licenses, Who Pays

Miami-Dade County had 488,281 residents 65 and over on July 1, 2024, 17.2% of the county (Census Bureau population estimates, Vintage 2024), the most of any Florida county and the seventh-largest count of any county in the United States. The median home was built in 1980 (Census American Community Survey), the county sits in the High-Velocity Hurricane Zone, and much of it lies in a flood zone, so a remodel in Miami runs into product approvals and the FEMA 50% rule that most of Florida can ignore. Structural, plumbing and electrical work needs a Florida DBPR license, and Miami-Dade's Construction Trades Qualifying Board issues its own Certificate of Competency. The projects that come up most are the curbless shower, grab bars, widened doorways for a wheelchair, and a step-free entry.

Miami by the numbers

• 488,281 residents of Miami-Dade County were 65 or older in 2024, 17.2% of the county, below Florida's 21.8% but the largest count in the state (Census Bureau population estimates, Vintage 2024).
• The county's median home was built in 1980, and 1.3% of its homes are mobile homes (Census American Community Survey, 2024 5-year).

Miami's seniors live everywhere: 1950s block homes, coastal condo towers, and 3 generations under one roof sharing a bathroom.

The homes here

A 1980 median build year puts half of Miami-Dade's homes before 1980: concrete block on a slab, terrazzo or glossy tile, narrow doors and an original bathroom. In a coastal condo tower the association controls flooring, exterior doors and plumbing changes; get its rules in writing first.

The entry. Most block homes have a step at the front door. A ramp or a regraded walk fixes it, but a new or wider front door in the High-Velocity Hurricane Zone must carry a Miami-Dade Notice of Acceptance. The state code's exception for some 1 and 2 family homes permitted before March 1, 2002 exists on paper; ask the contractor whether it applies inside the zone. See ramps, entries and thresholds.

The doorways. Older homes here have narrow bathroom and bedroom doors; a wheelchair needs a 32 to 36 inch clear opening, and widening is cheap in a partition wall and expensive in a load-bearing block wall. See widened doorways and hallways.

The bathroom. A 1970s bathroom has a tub or a curbed shower and a slick floor. A curbless shower on a slab means cutting the slab or building up the floor for drainage, and the exhaust fan must vent outdoors, not into the attic. See bathroom safety remodels and non-slip flooring for the terrazzo.

Flood zones. In a special flood hazard area, an improvement costing 50% or more of the structure's market value is a substantial improvement, and the whole home must then meet code, including elevation. A 2025 state law (SB 180) stops local governments from adding up smaller projects over a look-back period, but one large remodel on an older ground-level home can still hit the line. Get the structure value first.

Licensing and permits in Miami-Dade County

Florida requires a DBPR license (Certified General, Building or Residential Contractor; plumbing and electrical are separate) for structural, plumbing or electrical work; check it at the DBPR license search. Miami-Dade's Construction Trades Qualifying Board issues a county Certificate of Competency for some trades, and the county's online lookup shows county certificates only, so run both searches. Since Florida's 2021 preemption law (HB 735), a county certificate mirrors a state category or is a journeyman card. The contractor pulls the permit. The Florida page has the full state rule.

Who pays

Most Miami families pay directly, from savings, home equity or adult children splitting the cost: no pre-approval, your choice of contractor, work can start this week (paying out of pocket). Original Medicare pays nothing toward a remodel; some Medicare Advantage plans sold in Miami-Dade include a bathroom safety allowance (Medicare and Medicare Advantage). Florida's Medicaid agency is the Agency for Health Care Administration; ask it what home modification coverage exists and whether there is a waitlist. The Area Agency on Aging for Miami-Dade is based in Miami; reach it through the Elder Helpline at 1-800-963-5337 and ask whether the county's SHIP housing rehabilitation plan or Rebuilding Together Miami-Dade has an open program, both with income limits and waitlists.
