Removing a Load-Bearing Wall for a Kitchen: What to Know First

Source: This Old House, How to Know If a Wall Is Load-Bearing.

Signs a kitchen wall may be load-bearing

You can't confirm a bearing wall by knocking on it, but you can spot the clues that tell you to get it checked. This Old House points to two main ones:

• Joist direction. Look at the floor joists from the basement or the ceiling joists from the attic. If the wall runs perpendicular to the joists, it is probably carrying them.
• What's underneath. Load-bearing walls typically line up with support in the foundation below: a steel or wood beam, or a concrete wall.

As general guidance, other reasons for suspicion include a wall near the middle of the house, a wall with another wall stacked directly above it on an upper floor, and any wall in a home where you can't see the framing. None of these clues is proof either way. Treat them as reasons to call an engineer, not as permission to start cutting.

Why you need an engineer and a permit

A load-bearing wall is part of a path that carries weight from the roof and upper floors down to the footings. Remove it and that weight still needs somewhere to go. A structural engineer works out how much load the wall carries, specifies the beam and posts to replace it, and checks that the support below each post can take the new concentrated load. Both This Old House and other homeowner guides advise having an engineer verify the wall before removal.

The permit is not optional. The City of Holladay Building Division's FAQ says all structural and some nonstructural work requires permits, and remodels need permits regardless of square footage. Applications go through the city's online iWorQ portal, and the city says it strives to complete the first plan review within 7 business days. State law also sets an outer limit: for a one- or two-family dwelling, a municipality must finish plan review no later than 14 business days after the application's screening period ends. If you have questions before applying, the Building Official holds consultations by appointment on Mondays and Wednesdays, 3:30 to 5:00 pm.

Beam options: flush or dropped

The beam that replaces the wall can go in one of two places, and the choice changes how the opened room looks.

Beams can be engineered wood or steel, and the right material and depth depend on the span, the load and the space available. We haven't found a reliable source that compares them in general terms, and a general rule wouldn't fit your house anyway. Ask your engineer why the specified beam was chosen and whether a flush installation is practical in your ceiling.

Point loads: following the weight to the foundation

A wall spreads its load along its whole length. A beam gathers that load and drops it at two points, the posts at each end. This Old House notes that those posts must sit over the weight-bearing beam in the floor below so the load transfers to the foundation. If there's no support under a post, the engineer may call for a new footing, blocking or a post in the basement.

Utilities inside the wall

Kitchen walls are crowded. The wall you want gone may hold a drain and vent stack, water supply lines, a gas line, branch circuits for outlets and lights, a thermostat or a heating duct. Each one needs a new path before the wall comes out, and some of those paths aren't obvious. A vent stack, for example, can't just be moved sideways anywhere; the plumber has to find a route that still meets code. In Holladay, plumbing work (gas lines, drain-waste-vent piping, water lines) and new electrical circuits require permits of their own.

As general guidance, nearby soffits can also conceal ductwork, venting, plumbing or wiring, so ask your remodeler to open or inspect them during planning. And because most Holladay homes are older, test before you tear: EPA's lead-safe rules cover paid work that disturbs paint in homes built before 1978, and Utah requires contractors to have an asbestos inspection by a certified inspector before renovation.

Wasatch Front seismic context

Holladay sits along the Wasatch Front, and that matters when you change a house's structure. A 2016 USGS fact sheet, summarizing the Working Group on Utah Earthquake Probabilities, puts the probability of one or more magnitude 6.75 or greater earthquakes in the Wasatch Front region at 43% in the next 50 years, and of one or more M6.0 or greater at 57%. The probability of an M6.75 or greater quake on the Wasatch fault zone itself is 18%. The fault corridor is home to nearly 80% of Utah's population.

The March 18, 2020, magnitude 5.7 Magna earthquake was, in the Utah Geological Survey's words, an expected earthquake; the same forecast gave a 93% probability of one or more M5+ earthquakes in 50 years. UGS also notes that houses built before 1975 aren't built to today's earthquake codes, though they can be retrofitted, and that unreinforced brick or masonry houses are more susceptible to damage than wood-frame ones. Utah's URM risk-reduction strategy counts more than 140,000 unreinforced masonry buildings across the Wasatch Front built before they were prohibited in the 1970s.

With a median build year of 1969, many Holladay homes predate those modern codes. Our view, not a code requirement: in a pre-1975 or brick home, an engineer's review of any bearing-wall removal is the minimum sensible step.

What drives the cost

Wall removal cost depends on the load, the span, the beam, whether a flush beam means reframing the ceiling, how many utilities must move, and what the patching and flooring involve. For national context only, HomeAdvisor publishes these ranges. They are not Holladay quotes and do not include the rest of a kitchen remodel.

HomeAdvisor notes that rerouting plumbing and electrical, mold or asbestos remediation, and permits add to those figures. In a kitchen, the wall is usually one line item inside a larger remodel, which is why it should be priced with the new layout, not on its own.

How a well-planned wall removal runs

1. Plan the new kitchen firstDecide the layout that justifies the opening, so the beam location and post positions suit it.
2. Investigate the wallCheck joist direction, what's below, and what utilities run inside; test for asbestos and lead where required.
3. Get the engineeringThe engineer specifies beam, posts and any new footings.
4. PermitSubmit structural, plumbing and electrical scope to the Holladay Building Division through iWorQ.
5. Shore, remove, installTemporary supports go in before the wall comes out; the beam and posts go in before the shoring comes out.
6. Inspect, then close upFraming and rough-in inspections happen before drywall, then the floor and ceiling are patched.
