If the upper floors of a multi-story building are gutted down to the floor slab of each floor — but the building's ceilings, floors, and end walls stay standing — does rebuilding those upper floors count as untaxed new construction, the same way gutting a one-story building down to its slab would?

Plain-English summary

A hotel renovation project in an economic redevelopment zone (not an enterprise project) involved two kinds of work on a multi-story property: remodeling the lower floors' existing improvements (which the taxpayer agreed was taxable remodeling), and completely gutting the upper floors down to each floor's slab, leaving only the internal structural columns holding up the floor slabs and the two end exterior walls. The taxpayer had previously been told that for a one-story building, demolishing down to the slab with no exterior framing or walls remaining makes the subsequent rebuild untaxed new construction — and asked whether the same rule extends to the upper floors of this multi-story building, since each of those floors was similarly gutted to its own slab.

The Comptroller said no — that one-story rule doesn't transfer floor-by-floor to a multi-story building. Rule 3.357(a)(8) defines remodeling/modification as making over, rebuilding, replacing, or upgrading existing real property. Reviewing photos of the project, the Comptroller found the upper floors were being gutted, not demolished to the building's actual foundation — the building's ceilings, floor structures, and supporting columns remained standing throughout. So the entire charge for labor and materials to gut and rebuild those upper floors is taxable as remodeling, not exempt as new construction.

The letter draws the multi-story line clearly: to qualify as new construction in a multi-story building, you'd need to demolish the entire building down to its ground-level slab or foundation, with no walls or ceilings remaining anywhere above that foundation, before building anew — not just strip each floor down to its own floor slab while the building's overall structure stays intact.

This tracks a cited Comptroller's Decision (No. 34,112), where interior demolition left a building's floor, walls, and ceiling in place (stripped down to bare structural surfaces, in anticipation of further modification) but never reached the building's actual foundation slab. The Administrative Law Judge in that case found no support anywhere in Comptroller decisions, statutes, or rules for treating any partial demolition of an existing improvement as a nontaxable event — concluding that interior demolition or demolition of a portion of an existing improvement is itself taxable "modification, making over, or upgrading" under Tax Code § 151.0101(a)(13) and Rule 3.357(b)(2).

What this means for you

Owners and contractors renovating multi-story or high-rise buildings

Gutting individual floors down to their own floor slabs, however extensive, is still taxable remodeling as long as the building's overall structure (ceilings, floor slabs, supporting columns, exterior walls) remains standing. To get untaxed new-construction treatment, the entire building must come down to its ground-level foundation — a much higher bar than demolishing floor-by-floor.

Businesses assuming a "gut renovation" is treated like new construction

Even a "complete gutting" of a floor — removing everything down to bare structural surfaces — is not the same as demolition to the slab/foundation. Interior demolition of a portion of a building, by itself, is a taxable event (per Decision No. 34,112), not a tax-free preliminary step.

Accountants and tax professionals

This letter is a clear extension of the one-story slab-demolition rule into the multi-story context: the relevant "slab" for new-construction purposes in a multi-story building is the building's ground-level foundation, not each individual floor's own slab. Useful for scoping any large renovation or adaptive-reuse project.

Common questions

Q: If we gut a floor of a multi-story building down to its own floor slab, is rebuilding it untaxed new construction?
A: No. That's taxable remodeling, because the building's overall structure (other floors, ceilings, supporting columns) remains standing — the one-story "demolish to slab" rule doesn't apply floor-by-floor.

Q: What does it actually take for a multi-story building renovation to count as new construction?
A: The entire building must be demolished down to its ground-level slab or foundation, with no walls or ceilings remaining above that foundation anywhere in the building, before new construction begins.

Q: Is interior demolition itself ever a nontaxable, standalone step?
A: No — per Comptroller's Decision No. 34,112, demolishing a portion of an existing improvement to realty is itself taxable modification/remodeling under § 151.0101(a)(13) and Rule 3.357(b)(2), not a tax-free preliminary activity.

Q: Can I rely on this letter for my own renovation project?
A: No. This opinion is based on the facts presented, and other facts, though similar, may provide a different result; it binds the Comptroller only as to the taxpayer it was issued to.

Original ruling text

January 30, 1998

Dear **:

This is in response to your request for a ruling requesting clarification
concerning new construction versus remodeling under Section 3.357. You also
submitted requested additional information in the form of pictures of the
building in question. Your original fact situation and questions are restated
below followed by my response.

You have a multi-story property that will have construction of two kinds. On
the lower floors, you will be remodeling existing improvements, which you agree
is taxable remodeling. You were previously told by this office that if
improvements are completely demolished to the slab of a one story building and
no exterior framing and walls exist, then the subsequent improvements are
considered new construction.

The upper floors are being completely demolished down to the floor slab. No
exterior walls (except for the exterior walls on either end, per the pictures
provided) or framing will exist on these upper floors, leaving the internal
structural columns holding up the different floor slabs. If such a scenario is
then new construction for a one story building, are the improvements to these
upper floors, in this example, considered new construction as well?

You were told on a preliminary basis by our office that a key to determining
new construction was whether exterior framing and walls remained. The person
you spoke with suggested that you write and seek an interpretation.

**, of the City of **' Economic Development Department,
informed Mr. Burrell Lankford, of this office, and myself that this project
involves the renovation of a hotel that is located in an economic redevelopment
zone, but is not designated as an enterprise project.

Response: Subsection (a)(8) of Rule 3.357 - Labor Relating to Nonresidential
Real Property Repair, Remodeling, Restoration, Maintenance, New Construction,
and Residential Property, defines remodeling or modification as "(t)o make
over, rebuild, replace, or upgrade existing real property."

Based on your description and a review of the pictures provided, it appears
that you will be gutting the upper floors before upgrading the existing real
property, rather than demolishing them to the foundation (as ceiling supports,
ceilings and floors of the building will remain). Therefore, your total charge
for labor and materials to gut and rebuild the upper floors is taxable as
remodeling rather than new construction.

In order to qualify as new construction, where you have a multi-story building,
you would need to demolish the building to its slab or foundation with no
remaining walls or ceilings existing above the ground floor slab or foundation,
before constructing a new building on that site.

In Decision No. 34,112, involving a similar issue, interior demolition work was
performed in multiple story buildings. The demolition work consisted of taking
down all materials on a building's floor so that nothing remained except the
floor, walls, and ceiling (generally in contemplation of additional
modifications being made to the buildings). None of the jobs involved the
demolition of a building down to its slab. It was determined that while
demolition "down to the slab" was a non-taxable service, demolition to slab of
a floor was not nontaxable. The Administrative Law Judge states in that
Decision that:

I am unaware of any Comptroller's Decisions, statutes, rules, or taxability
responses that support the position that "demolition" of a portion of an
existing building or other improvement to realty is a non-taxable event.
Therefore, I recommend that interior demolition, or demolition of a portion of
an existing improvement to realty, should be considered the modification,
making over, or upgrading of the improvement and taxable pursuant to Section
151.0101(a)(13) and Rule 3.357(b)(2).

This opinion is based on the facts presented. Other facts though similar may
provide a different result.
