Condo Renovation
Renovating a condo unit in a Miami-Dade, Broward, or Palm Beach high-rise means working inside a second layer of rules that a single-family home renovation never touches. Before a city permit gets pulled, most buildings require the homeowner to get their own association’s approval — a formal alteration agreement covering exactly what you’re allowed to change, what hours contractors can work, what insurance you need to carry, and how materials and debris move through common areas.
Structural slabs, exterior walls, balconies, and plumbing stacks are shared building components, not private property, which means the scope of what a unit owner can actually change is narrower than in a house — and anything touching those elements typically needs a structural engineer’s letter before the association or the city will even look at it.
We manage both tracks — city permitting and building approval — as one coordinated process, because in practice a condo renovation doesn’t really start until the association signs off, regardless of how ready your permit package is.

What you can and can't change.
Inside a condo unit, interior demising walls, flooring, cabinetry, and the electrical and plumbing systems that serve only your unit are typically within an owner’s control, subject to association rules. Structural slab, exterior walls and windows, balconies, and the plumbing stacks that run through multiple units are common elements, and altering them — even from inside your own unit — usually requires association approval at minimum and often a structural or MEP engineer’s letter confirming the change won’t affect the building’s structural integrity or shared systems.

Alteration agreements and board approval.
Most Miami-area buildings require a formal renovation application before permits are submitted — plans, scope description, contractor insurance certificates, and often an engineering letter for anything touching plumbing stacks or interior walls that might be load-bearing. Board or management approval commonly takes two to six weeks depending on the building’s meeting schedule and review process, and for a full gut renovation, it’s realistic to budget at least a month, sometimes closer to three, for approvals alone before construction can begin — building management typically won’t let you schedule the freight elevator or mobilize trades until that approval is in hand.

Building rules after Surfside.
Since the 2021 Surfside condominium collapse and the state structural-safety laws that followed — mandatory milestone structural inspections and reserve-funding requirements for condo buildings — many associations have tightened their alteration agreements specifically around anything touching structural or building-system components. Expect more scrutiny on wall removal, plumbing stack work, and balcony alterations than would have been typical a decade ago, and expect engineering documentation to be a standard requirement rather than an occasional one.

Living with building logistics.
Beyond approvals, condo renovations run on the building’s terms: restricted work hours (often limited to weekday daytime, sometimes with reduced hours or no work at all on weekends), scheduled freight elevator access, protected pathways for material and debris through common hallways and lobbies, and advance notice to neighboring units. These logistics genuinely slow construction down compared to a house, which is a real part of why condo renovations run 20-40% higher per square foot than comparable single-family work.

What Drives The Cost
- Board approval and logistics timeline — buildings with stricter or slower review add real project cost through extended mobilization and holding costs
- Structural engineering letter requirements — any scope touching shared plumbing stacks or potentially load-bearing walls adds engineering cost
- Restricted work hours and elevator scheduling — fewer working hours per week extends the construction calendar and labor cost
- Flooring and sound requirements — building-mandated underlayment and acoustic specifications add material and labor cost beyond standard flooring installation
- Unit access constraints — high floors, small service elevators, and limited staging space slow material handling
- Finish level — the same wide range as any renovation, but condo logistics compress the margin between budget and luxury finish costs more than in a house

Condo Renovation Questions, Answered
1 Do I need my condo association's permission to renovate, or just a city permit?
Both, and in most buildings the association approval has to happen first — buildings typically won't let you submit for permits, schedule the freight elevator, or mobilize contractors until the board or management has formally approved your renovation package.
2 Can I move plumbing or remove a wall in my condo?
Sometimes, but plumbing stacks and potentially load-bearing walls are often shared building elements, which usually requires a structural or MEP engineer's letter confirming the change is safe before the association or city will approve it.
3 How long does condo board approval take in Miami?
Typically two to six weeks depending on the building's review process and meeting schedule, though a full gut renovation application can realistically take a month or more given engineering letter requirements and board meeting timing.
4 Why do condo renovations cost more per square foot than a house?
Restricted work hours, freight elevator scheduling, mandatory debris protection through common areas, engineering letter requirements, and stricter noise/dust rules all slow construction down — condo renovations commonly run 20-40% higher per square foot than comparable single-family work as a result.
5 What's an alteration agreement and why does my building require one?
It's a contract between you and the association governing what you're allowed to renovate, when work can happen, what insurance you must carry, and how the building's common elements are protected during construction. Nearly every Miami-area condo building requires one before renovation work can start.
6 Are there rules about what hours contractors can work in my building?
Almost always — most buildings restrict work to weekday daytime hours, and many limit or prohibit work entirely on weekends. These hours are set by the building, not by us, and they're a real factor in how long a condo renovation takes compared to a house.
7 Has it gotten harder to renovate a condo since the Surfside collapse?
In many buildings, yes. Post-Surfside structural safety laws led many associations to tighten alteration agreements around anything touching structural or shared building systems, so expect more engineering documentation requirements than a decade ago.
8 Can I install a washer/dryer or change my flooring type in a high-rise unit?
Depends entirely on your building's rules — many associations restrict in-unit washer/dryer installation due to plumbing and leak-risk concerns to units below, and flooring changes often require sound-dampening underlayment specifications to meet the building's noise transmission standards.
