Schwalm Studio
REPLACEMENT COST SUMMARY
The replacement cost was calculated in its current condition and does not factor in necessary updates to
meet today’s code standards.
Existing insulation R-value does not meet energy code.
Existing electrical outlets do not meet electrical code.
Existing windows are single-paned and do not meet energy code.
The replacement cost of the existing studio was calculated EXTREMELY conservatively.
The replacement cost was only calculated using fixed material and labor costs to compare versus
demolition; the cost to replace does not factor in permitting costs, or contractor fees. Furthermore, this
replacement cost does not factor in contractor’s site prep, excavation, dumpster, toilet, or equipment
rental fees.
CALCULATION OF REPLACEMENT COST
The exterior of the existing studio is to remain mostly intact, with the majority of the renovation being
an interior remodel.
The major cost items: roofing, wall framing, and foundation (including existing crawlspace and floor
framing) all remain.
Per Sec.38.320.040 of the Bozeman Municipal Code (Nonconforming Structures) b. “The right to
operate a nonconforming structure terminates when the structure is destroyed by any means of
more than 50 percent of its replacement cost at the time of destruction.”
Maximum Percentage of Replacement Cost Demolished: 45%
