A full condo renovation in Miami typically runs about $150 to $250 per square foot for a mid-range to upper-mid gut. Lighter work, such as new floors, paint and a kitchen or bathroom refresh, usually lands around $60–100 per square foot. High-end oceanfront interiors are priced individually after design. On top of the construction itself, the building adds costs that a house never has: approvals, insurance certificates, acoustic flooring rules, restricted hours, elevator bookings and controlled debris removal.
Current Florida market data puts condo work at roughly 10–25% more than comparable work in a single-family home, and some local data puts the per-square-foot premium higher. Here is where that money goes, and how to read a condo budget before you sign one.
How much does it cost to renovate a condo in Miami per square foot?
Per-square-foot numbers for condos are useful as a sanity check, but only if you know what scope they describe. A 1,200-square-foot apartment with two bathrooms and a kitchen is mostly kitchen and bathrooms by cost, so the number per foot rises fast once those rooms are included.
| Scope | What it usually includes | Typical Miami range per sq ft |
|---|---|---|
| Cosmetic refresh | Paint, new flooring with approved underlayment, lighting, doors and hardware | $60–100 |
| Partial renovation | Kitchen and one or two bathrooms remodeled, new floors throughout | $100–150 |
| Full gut, mid to upper-mid | Everything to the slab and block, electrical and plumbing re-run, new kitchen, baths, ceilings, doors, millwork | $150–250 |
| Luxury, oceanfront tower | Custom millwork, slab stone, architectural lighting, automation, imported finishes | Priced individually after design |
As totals, current local data puts a mid-range gut renovation of a 1,000–1,500-square-foot Miami condo at roughly $125,000–225,000, and a standard two-bedroom full-apartment renovation at about $100,000–175,000. Within those, a condo kitchen typically runs $35,000–55,000 and each bathroom $25,000–40,000. These are market ranges, not a quote.
Why the building adds cost
None of the items below make the apartment look different. They are the cost of working inside an occupied building with neighbors above, below and on either side. A contractor who leaves them out of the proposal has not saved you money. They have moved the cost to a change order.
Board approval and documentation
Most associations require a written application with the scope, drawings for anything beyond cosmetic work, the contractor’s details and the permit. Board review alone can take two to six weeks. During that time nothing can start, which matters if you are paying rent elsewhere or coordinating a move. On our Bay Harbor apartment project, board approval was a defined phase of the schedule, not something that happened in the background.
Certificates of insurance
Buildings want a certificate of insurance from the general contractor and often from every subcontractor, naming the association and sometimes the management company as additional insured, with minimum limits the building sets. Contractors with thin coverage either cannot work in the building or pay to raise their limits for that job. Either way it shows up in the price.
Acoustic underlayment for hard flooring
The Florida Building Code sets a minimum sound rating of STC 50 and IIC 50 for floor-ceiling assemblies between dwelling units, and many Miami buildings set their own target higher, commonly IIC 55 or 60 in luxury towers. In practice that means an approved acoustic underlayment under tile, stone or wood, installed to the manufacturer’s tested assembly, and sometimes proof of the rating before the board signs off.
The underlayment is a material cost, but the bigger cost is labor: perimeter isolation, careful leveling and, in some buildings, a field test. We explain the ratings in condo soundproof flooring: IIC and STC, and flooring choices in the best flooring for Florida homes.
Restricted working hours
Many buildings allow construction only on weekdays, within a set window, and noisy work such as demolition, coring or tile cutting within an even shorter one. A job planned for six weeks of normal hours can easily stretch to eight or nine (more on scheduling in how long a renovation takes). Every extra week is labor cost and, for you, time out of the apartment.
Elevator reservations, protection and deliveries
Materials and debris move only in the service elevator, only when it is reserved, and only after the cab, the lobby and the corridor are protected. Some buildings charge for elevator use. Large items such as slab stone, long cabinet runs and full-height glass have to fit the cab, which affects how they are ordered and fabricated. Local data puts building logistics alone at roughly $2,000–5,000 per project, plus a refundable construction deposit commonly in the $5,000–10,000 range.
Debris removal
You cannot park a dumpster outside a tower on Collins Avenue. Debris is bagged, carted through protected corridors, taken down in the reserved elevator and removed from a loading area on a schedule. It is slower and more labor-intensive than tossing debris from a house into a container in the driveway.
Plumbing and electrical in a high-rise
The biggest cost decision in a condo is whether anything moves. Kitchen and bathroom drains connect to building risers that serve every unit in the stack. Moving a sink a few feet may be simple. Moving a toilet or a kitchen to the other side of the apartment can require coring the slab, scanning for post-tension cables, association engineering review and, in some buildings, it is not permitted at all.
On the Bay Harbor project the work involved the shared riser, a floor that had to be levelled and services re-run throughout, which is typical of a full condo gut. If a layout change is on your list, read moving plumbing in a condo high-rise before you design around it. Relocated plumbing, slab levelling and tight building logistics are the hard parts of a condo job, and they are where we do our best work.
What else moves the number
- Slab condition. Older buildings often have floors out of level by more than tile and wood tolerate. Self-leveling compound over a whole apartment adds material and time.
- Ceilings. Dropping ceilings for recessed lighting and new ductwork is common and adds framing, drywall and electrical.
- Air conditioning. Many condo air handlers sit in a closet inside the unit. Replacing one in a renovation is easier than later, but the unit and access rules vary by building.
- Windows and sliding doors. Replacements need a permit and, in most buildings, must match the association’s approved product and appearance.
- Finish level. In a 1,200-square-foot apartment, the gap between stock cabinetry and custom millwork alone can exceed $15,000 in the kitchen.
- Building condition and timing. Buildings going through structural repairs or milestone inspections may limit or pause unit work. See Florida condo milestone inspections.
A realistic way to budget a Miami condo renovation
- Get the building’s alteration rules in writing first, including hours, flooring requirements, deposit, insurance limits and what may and may not be relocated.
- Decide whether plumbing moves. That one decision sets the budget tier.
- Price the kitchen and bathrooms as separate line items; together they are usually most of the total.
- Add the building costs as their own section: deposit, elevator, protection, debris, extended schedule.
- Hold a 10–20% contingency, toward the upper end in older buildings.
We work in buildings across Aventura, Sunny Isles Beach, Bal Harbour, Surfside, Miami Beach and Hallandale Beach, and as an HOA-approved contractor we know the paperwork side as well as the construction side. Our condo renovation page explains how we run these jobs, and condo renovation rules in Miami covers the approval process. If you will not be living in the apartment during the work, read renovating a condo while you are away.
A real number comes from a site visit and the building’s rules, not a square-foot multiplier. We look at the slab, the riser locations, the electrical panel and the condition of what is behind the walls, then write a scope you can compare line by line.
Frequently asked questions
How much does it cost to gut a 2-bedroom condo in Miami?
Current local data puts a full renovation of a standard two-bedroom Miami condo at roughly $100,000–175,000. Mid-range finishes in the same layout sit toward the lower half. Relocating plumbing, custom millwork, slab stone or a luxury oceanfront building push it higher and are priced after design. Building logistics and approval time come on top of construction.
Why are condo renovations more expensive than houses?
The construction is similar, but the conditions are not. Condo work carries board approval, insurance certificates naming the association, construction deposits, service elevator scheduling, corridor protection, restricted hours, acoustic flooring rules and controlled debris removal. Florida market data puts that premium at roughly 10–25%, mostly in labor time and logistics rather than materials.
Do I need a permit to renovate my condo in Miami?
Painting, flooring and replacing cabinets generally do not need a building permit, although the association still has to approve them. Electrical work, plumbing changes, removing walls, windows and doors do require a permit from the city where the building is located. Most associations will not approve permitted work without seeing the permit first.
What soundproofing is required for condo floors in Florida?
The Florida Building Code requires floor-ceiling assemblies between dwelling units to meet STC 50 and IIC 50. Many Miami buildings set stricter targets in their own rules, commonly IIC 55 or 60 in luxury towers. That usually means an approved acoustic underlayment under hard flooring, installed exactly as tested, and sometimes documentation for the board.
How long does a full condo renovation take in Miami?
Plan on four to twelve weeks before construction for design, permits and board approval, then roughly twelve to twenty-four weeks of construction for a full apartment. Restricted working hours and long-lead items such as custom cabinetry or imported stone are the usual reasons projects run longer than planned.
Can I move my kitchen or bathroom in a high-rise condo?
Sometimes. Drains connect to shared risers, so relocating a toilet or kitchen sink may require coring the slab, scanning for post-tension cables and engineering approval from the association. Some buildings prohibit it entirely. Ask for the building’s alteration rules before designing a new layout, and expect relocation to move your budget into a higher tier.
