Those are our typical costs in the St. Louis metro area for a full, same-layout remodel of a 40 sq ft bathroom ($19,100 – $44,700) and a 150 sq ft kitchen ($28,600 – $57,200).

How St. Louis compares
We start from the 2025 Cost vs. Value report's figures for the West North Central division[2], then adjust for local labor. Across the construction trades BLS publishes for the St. Louis, MO-IL metro, the median wage is 21% above the U.S. median (ratio 1.21) and 14% above the West North Central average (ratio 1.06).[1] Because labor is roughly half of a remodel's cost by our assumption, we move the division's index halfway toward that local wage difference.
| Kind of work | U.S. | West North Central Estimate | St. Louis Estimate |
|---|---|---|---|
| Interior | 1.00 | 1.02 | 1.09 |
| Roofing | 1.00 | 0.97 | 1.04 |
| Exterior | 1.00 | 1.01 | 1.08 |
| Additions | 1.00 | 1.01 | 1.08 |
Estimate Derived, not published. Metro factor = division index × (1 + 0.5 × (metro wage ratio ÷ division wage ratio − 1)).
Construction wages in the St. Louis area

Get the templateHousing stock and what it means for your budget
Half the homes in the St. Louis metro were built in 1974 or earlier, and about 58% were built before 1980.[3] Sourced The median owner-occupied home is valued at $268,300, and 71% of homes are owner-occupied.[3] Sourced At our typical St. Louis price, a full kitchen remodel equals about 15% of the median home value. Estimate
Older housing means more surprises behind the walls: galvanized pipes, undersized wiring, old repairs and rot. For a same-layout remodel of a typical home here, we'd hold a contingency of about 15% – 20% because the median home is 30 or more years old. Estimate See our contingency guide. Work that disturbs paint in homes built before 1978 must be done by EPA lead-safe certified contractors.[7]
Climate and building considerations
The independent city of St. Louis is in IECC 2021 climate zone 4A (Mixed-Humid).[4] Sourced This is a mixed climate with real heating and cooling seasons. Winter freeze-thaw cycles are hard on concrete, masonry and exterior paint, and footings still need to reach the local frost depth. Humid summers make moisture control part of every bathroom and basement job: an exhaust fan vented outdoors, proper waterproofing behind tile, and a dehumidification plan for finished basements.
Permits in St. Louis
In the city of St. Louis, residential building permits go through the Building Division. The metro spans MO, IL, and suburbs and unincorporated areas have their own building departments, so check with the city or county where the house sits. Expect a permit for anything that moves plumbing, adds circuits, changes structure or adds space; paint, flooring and same-spot fixture swaps usually don't need one. Other metros in the West North Central division: Minneapolis, MN, Kansas City, MO.
Permit fees in St. Louis
We haven't yet verified a current residential fee schedule for St. Louis, so we don't quote one here. Most U.S. building departments price remodel permits from the project's value or floor area, with trade permits (plumbing, electrical, mechanical) and plan review on top. Ask the Building Division for the fee before you budget, and check whether your contractor's bid includes it.
