Whole-Home Renovation

Most South Florida homes hit a point where painting the walls and swapping the countertops stops being enough. A 1970s Kendall ranch, a 1980s Plantation split-level, or a 1990s West Palm Beach two-story eventually reaches the age where the electrical panel is undersized, the cast-iron drain lines are failing from the inside out, and the layout was designed for a family that doesn’t live there anymore. A whole-home renovation addresses all of it at once — structure, systems, and finishes — rather than chasing problems room by room for the next decade.

This is the most comprehensive renovation scope we offer short of a teardown: every room touched, every major system evaluated, and the home effectively rebuilt inside its existing walls and foundation. It’s the right call when a house needs more done than any single room-by-room budget or timeline can justify.

Because a project this size touches structural, electrical, plumbing, and mechanical systems simultaneously, it also carries the most permitting complexity of any renovation scope — and, for the many tri-county homes sitting in a FEMA flood zone, a real possibility of tripping a federal compliance threshold that has nothing to do with your taste in cabinetry. We plan for both from day one.

What actually counts as "whole-home."

A whole-home renovation doesn’t necessarily mean demolishing the house to its studs and slab, though it can. More often it means keeping the structural shell, footprint, and roofline the homeowner likes, while gutting and rebuilding everything inside it — every wall finish, every fixture, every linear foot of wire and pipe, and frequently the layout itself, opening up rooms that were chopped up by 1970s-era construction habits. The defining feature isn’t demolition intensity; it’s scope. If the project touches every major room and every major system in one continuous construction period, it’s a whole-home renovation rather than a series of individual remodels.

Permitting a project this size.

Florida’s new HB 803 exemption, effective July 1, 2026, lets homeowners skip a permit for isolated work under $7,500 that doesn’t touch electrical, plumbing, mechanical, gas, or structural systems — but a genuine whole-home renovation blows past that threshold on essentially every front. Expect a full permit package: building, electrical, plumbing, and mechanical at minimum, often with structural engineering drawings if walls are moving or the roof structure is affected. Every open permit on a property also gets counted toward flood-compliance calculations, which matters more here than on almost any other renovation type we handle.

The FEMA 50% rule and older tri-county homes.

A large share of pre-1990s homes in Miami-Dade, Broward, and Palm Beach sit inside a FEMA Special Flood Hazard Area, and federal floodplain rules — the “Substantial Improvement” rule under 44 CFR 59.1 — require that once cumulative renovation cost reaches 50% of the structure’s market value (not the land, and not counting the cost of the land), the entire structure must be brought up to current flood code. That can mean elevating mechanical and electrical equipment at least one foot above base flood elevation, or in more severe cases, elevating the structure itself. The lookback period that determines what counts toward that 50% varies by city — Miami uses a two-year cumulative window, Miami Beach uses one year, and other municipalities use longer windows — so a homeowner who did a $40,000 kitchen two years ago and is now planning a $150,000 whole-home renovation needs that math run before design starts, not after.

Living through it.

A full gut of an occupied home is disruptive in ways a single-room remodel isn’t — there’s realistically no functioning kitchen or bathroom for a stretch of the project, which is why most homeowners doing a genuine whole-home renovation either relocate temporarily or phase the work by wing so at least part of the house stays livable. We build that logistics conversation into scheduling up front rather than leaving it as a surprise once demolition starts.

What Drives The Cost

  • Total square footage touched — the baseline cost driver for any whole-home scope
  • Extent of structural change — moving load-bearing walls or reconfiguring the roof structure adds engineering and labor cost beyond finish-level work
  • Systems replacement scope — full electrical service upgrades and whole-house repiping cost significantly more than spot repairs
  • FEMA 50% rule exposure — if flood-compliance thresholds are triggered, elevation or mechanical relocation adds substantial cost beyond the renovation itself
  • Finish level and material selections — the widest swing factor between a $175/sqft and $270+/sqft project
  • Age and hidden condition of the home — older tri-county homes frequently reveal termite damage, outdated wiring, or moisture intrusion once walls open, which affects final cost more than initial scope

Evaluate structure, roof, electrical service, plumbing lines, and HVAC condition, plus a check of the property’s flood zone status and prior permit history for FEMA 50% rule exposure.

Develop the renovation plan and pull building, electrical, plumbing, and mechanical permits together, with structural engineering drawings where layout changes require them.

Strip the home to the point the scope requires — down to studs and slab where systems and layout are changing, preserved structure where the shell stays intact.

Rerun electrical, plumbing, and HVAC to current code, passing rough-in inspections before walls close.

Install finishes room by room, pass the final building inspection, and close out every open permit on the property.

Whole-Home Renovation Questions, Answered

1 How do I know if I need a whole-home renovation versus just remodeling my kitchen and bathrooms separately?

If you're looking at three or more major rooms needing work, an electrical panel that can't support modern loads, or plumbing old enough to be a leak risk, doing it as one coordinated project usually costs less overall than three or four separate remodels spread over years — you pay for mobilization, permitting, and dust protection once instead of repeatedly.

2 Will renovating my whole house trigger the FEMA 50% rule?

Only if your property sits in a FEMA-designated flood zone and your renovation cost, combined with any other permitted work in the applicable lookback period (one to two years depending on your city), reaches 50% of your home's structural market value. We check your flood zone status and run that math before finalizing scope.

3 Do I have to move out during a full home renovation?

For a genuine gut renovation, yes, in most cases — there typically isn't a functioning kitchen or bathroom for a meaningful stretch of the project. Some homeowners phase the work by wing to keep part of the house livable, which extends the timeline but avoids relocation.

4 What permits does a whole-home renovation actually require in Miami-Dade?

At minimum, building, electrical, plumbing, and mechanical permits, plus structural engineering drawings and a permit if you're moving load-bearing walls or altering the roof structure. Florida's 2026 permit exemption for work under $7,500 doesn't apply here — a whole-home scope crosses that threshold almost immediately.

5 How long does a full home renovation take from start to finish?

Design and permitting typically run 4-12 weeks for standard projects, longer if structural engineering or flood-compliance review is involved. Construction itself commonly runs 6-12 months depending on square footage and scope.

6 What's the difference between renovating and a full gut to the studs?

Renovating in place means keeping wall finishes, framing, and layout while updating fixtures and systems. A full gut removes interior finishes down to framing (or the exterior shell down to studs and slab), which is usually necessary when rerouting plumbing/electrical or reconfiguring the floor plan.

7 Can I keep my home's existing footprint and just redo everything inside?

Yes — that's the most common version of a whole-home renovation. Keeping the existing footprint and structural shell avoids the zoning, setback, and structural-engineering complexity of an addition while still letting you replace every system and finish.

8 What's the actual cost range for a whole-home renovation in South Florida?

Full-scope renovations in the Miami market commonly land between roughly $175 and $270+ per square foot depending on finish level and how much of the structure is touched, with Coral Gables and Miami Beach projects running 10-20% above that due to added architectural review requirements. A mid-range 2,000-square-foot whole-home renovation often falls somewhere between $210,000 and $540,000.
