Renovation vs. Remodel vs. New Construction

Renovation, remodel, addition or new construction?

The short answer

From a repair to new construction

Where each term sits on the code

The Florida Building Code, Existing Building volume (8th edition, 2023) does not use the words “renovation” or “remodel” at all. It sorts work on an existing structure into repairs (chapter 4), alterations (chapter 7, covering both a cosmetic renovation and a structural remodel) and additions (chapter 5). The chapter that applies, not the word used to describe the project, decides what the building department requires.

Layout and systems are the test

Renovation vs. remodel: the practical difference

The test is not the price or how much demolition happens – it is whether the layout, structure or building systems change. A full gut-and-replace of a kitchen that keeps the same footprint and plumbing runs is, by this test, a (large) renovation. Moving a sink six feet is a remodel, even if the rest of the job is small. See our kitchen planning guide and bathroom planning guide for how that distinction plays out room by room.

Adding on, or starting over

Addition vs. new construction

An addition adds new conditioned square footage to an existing structure – a bump-out, a second storey, or a detached suite connected to the main house by a breezeway. It always needs a permit, and chapter 5 of the Existing Building code (section 502.2) requires the existing structure to be brought into compliance too if the combined project crosses the substantial-improvement threshold below. New construction is a structure built from the ground up: it is designed to the current code in full from the first drawing, with no existing building to reconcile.

See our new home construction cost guide for the flood, wind and energy-code rules that apply to a ground-up build.

FEMA’s 50% rule

The cost of the work can outrank the label

None of these labels change what happens if a property sits in a Special Flood Hazard Area and the job is expensive enough. Under 44 CFR 59.1, a “substantial improvement” is “any reconstruction, rehabilitation, addition, or other improvement of a structure” whose cost equals or exceeds 50 percent of the structure’s market value before the work starts. Once that threshold is crossed, the Florida Building Code’s flood provisions require the whole structure – not just the new work – to meet current flood-elevation and other code requirements. A project called a “renovation” on the contract gets no exception.

See our FEMA 50% rule guide for how the 50% threshold is calculated, what counts toward the cost, and what the whole-structure compliance requirement involves.

The building department decides, by scope

Does it need a permit?

Florida law requires a permit for work that affects structure, electrical, plumbing, mechanical systems, fire protection or (in most cases) a change of occupancy; the exact list of what is exempt is set locally under section 553.79, Florida Statutes, and varies by city and county. In practice: a cosmetic renovation that touches only finishes often needs no permit, or a minor one; a remodel that moves plumbing, wiring or a wall needs one; an addition always needs one. We confirm the requirement with the building department before pricing a project, rather than guessing from the label a homeowner used to describe it.

Figuring out which one your project is

Our process

How we scope a project before we price it

We start by confirming what the work actually involves – layout, systems, square footage and flood zone – because that, not the word a homeowner uses, decides the permit path and the code requirements. From there we scope it as a kitchen remodel, a bathroom remodel, a whole-home renovation, or new home construction.

Tell us what you are considering and we will tell you which category it falls into and what permit it needs, before we talk about price.
