A feasibility study is what separates an informed decision from an expensive opinion. On a South Florida luxury property the tear-down-or-renovate question touches structure, flood regulation, zoning, insurance, cost, and schedule at once, and no single professional sees all six. The study exists to assemble them into one comparison, at the same specification, before anyone commits to a direction.
What is a feasibility study in this context?
A structured pre-purchase or pre-design analysis that establishes what a parcel and any existing structure will actually support, then prices and schedules the realistic options against each other. It is not a design exercise and not an appraisal. A feasibility study answers what is possible and what each possibility costs in money and time.
The decision it informs is framed in teardown versus renovation.
What does the study have to establish?
Seven findings: the existing structure’s condition and code position, the flood zone and required elevation, what current zoning permits, geotechnical and site constraints, the approvals path and its realistic duration, comparative cost for each option at one specification, and the insurance consequences of each. Anything less is a partial answer.
The flood component is detailed in flood zone requirements.
Why does the existing structure need a real assessment?
Because its condition determines whether renovation is genuinely cheaper or merely appears so. Foundation adequacy, structural framing, roof structure, and whether the building can accept the loads and openings the new plan requires are engineering questions. A feasibility study that skips them is guessing at the single largest variable.
The structural standard is described in hurricane-resistant construction.
How does the substantial improvement rule enter?
Decisively. In a mapped flood zone, improvement work above a defined threshold relative to the structure’s value triggers full compliance for the entire building, including elevation. Any credible feasibility study tests the intended scope against that threshold, because crossing it converts a renovation into a rebuild with a renovation’s constraints.
The elevation consequences are in elevated foundation and coastal home design.
What does zoning contribute?
Two things owners rarely check: what could be built today, which may be less than what stands, and what the existing building enjoys as a legal non-conforming condition that demolition would forfeit. A feasibility study that establishes this before demolition prevents the worst outcome in this decision, which is losing rights that could not be regained.
Local review is administered by Broward County and Palm Beach County.
| Finding | Who establishes it | Why it matters |
|---|---|---|
| Structural condition and code position | Structural engineer | Decides whether renovation is genuinely cheaper |
| Flood zone and required elevation | Surveyor and floodplain review | Triggers the substantial improvement rule |
| What current zoning permits | Architect and zoning review | Demolition can forfeit existing rights |
| Geotechnical and site constraints | Geotechnical engineer | Sets foundation cost on either path |
| Approvals path and duration | Builder and consultants | Often the longest item in the comparison |
| Comparative cost at one specification | Builder | Makes the comparison real rather than rhetorical |
| Insurance consequences | Insurance adviser | A recurring annual difference, not a one-off |
How should the cost comparison be built?
At one specification, so the comparison is real. Renovation priced to a lower finish level against new construction priced to a higher one is not a comparison, it is a preference expressed in numbers. A feasibility study prices both to the same programme, the same finish level, and the same code position, then shows the difference.
Cost structure is in the luxury construction cost breakdown.
What about schedule and carrying cost?
They belong in the comparison, because time is money on both paths. A custom build often runs 14 to 24+ months and a high-end renovation often 6 to 14+ months, and the renovation figure carries wider variance. A feasibility study should show the total holding period for each option, not just the construction duration.
The financial modelling is in renovation versus new construction.
When should the study be done?
Before purchase where possible, and always before design. Its whole value is that it is cheap relative to the decision and worthless once the decision has been made. Owners who commission a feasibility study during a due diligence period buy the ability to walk away, which is the most valuable thing it produces.
The purchase checklist is in what to know before building a waterfront home.
Who should perform it?
A team rather than an individual: a structural engineer for the existing building, a surveyor, an architect for zoning and programme fit, a builder for cost and constructability, and where relevant a coastal or marine engineer. The builder’s role is to convert the others’ findings into real numbers and a real calendar.

How does Kass Construction & Development run one?
As a decision document, not a sales document: Kass Construction & Development, a state-licensed (CGC1529472) boutique luxury builder led by Mitch Kass, a licensed general contractor and attorney, with 100+ luxury residences over 25+ years across Broward, Palm Beach, and Miami-Dade, delivers a feasibility study that prices both paths at one specification and states plainly which the evidence supports.

Frequently Asked Questions
What is a feasibility study for a luxury home?
A structured analysis of what a parcel and any existing structure will support, with the realistic options priced and scheduled against each other at one specification, before design begins.
When should it be done?
Before purchase where possible and always before design. Its value is that it is inexpensive relative to the decision and preserves the option to walk away.
What does it need to cover?
Structural condition, flood zone and elevation, current zoning, geotechnical and site constraints, the approvals path, comparative cost at one specification, and insurance consequences.
Why price both options at the same specification?
Because otherwise the comparison reflects finish level rather than strategy. Equal specification is what makes the difference between the paths meaningful.
Can demolition lose me rights?
It can. An existing building may enjoy legal non-conforming conditions that current zoning would not permit again, which is why zoning is checked before demolition rather than after.
Who should carry out the study?
A structural engineer, surveyor, architect, and builder, plus a coastal or marine engineer on waterfront parcels. The builder converts their findings into cost and schedule.
How long does a study take?
Long enough to obtain the survey, structural assessment, and zoning confirmation. It fits comfortably inside a normal due diligence period when started promptly.
