Short answer: almost any wall can come out. The real question in load-bearing wall removal is what has to replace it — a beam, posts, and a path for the load to reach the ground. That is where the work and the money are.
Here is how to tell what you are dealing with before you call anyone.
Plenty of interior walls hold up nothing but drywall. Three things say otherwise:
One more, specific to newer houses: if the roof is built from trusses spanning wall to wall, most interior walls carry nothing at all. The exception is a girder truss, which lands its load on a particular wall or post — so it is still worth confirming rather than assuming.
And a Bay Area caution: many of these houses have been remodeled once or twice already. Someone may have moved a load years ago without paperwork. Clues point; they do not prove. The wall gets confirmed by opening the ceiling or by an engineer looking at the whole path, not by a knock test.
A beam takes over the wall’s job. Its size depends on the span and on what sits above — one floor, or a floor plus a roof. Usually that is an engineered beam: LVL, PSL or glulam, or steel when the available depth is tight.
The part people miss is what happens at the ends. The beam lands on posts, and those posts have to keep going: down through the floor, onto a post or pad in the crawlspace, onto a footing in the ground. On a slab, that can mean cutting the slab and pouring a new pad.
That load path is where a straightforward-looking job turns into a bigger one. It is also why we will not quote a wall from a photo of the room.
While the wall is out, the ceiling is held up on temporary shoring — posts and beams set a few feet away on both sides, carrying the floor above until the real beam is in.
Same beam, same posts. The difference is the ceiling.
The honest test is ceiling height. Under an 8-foot ceiling, a beam hanging 10 or 12 inches down cancels some of the openness you paid for. At 9 or 10 feet, or in a room you are vaulting anyway, a dropped beam looks fine and saves real money.
One detail worth knowing: engineers often size these beams stiffer than the code minimum. Code limits deflection to about 1/360th of the span — the point of that limit is not strength, it is keeping the drywall and the floor above from cracking.
Walls do two jobs. They hold things up, and they keep the house from racking sideways in an earthquake. The code calls those braced wall lines.
Most of the Bay Area sits in a high seismic design category, so a meaningful share of each wall line has to be braced. Take out a long interior wall and the engineer has to put that bracing back: plywood shear panels at the ends of the opening, hold-downs tying them to the foundation, or a steel moment frame where there is no wall left to panel.
This is why two jobs that look identical from the kitchen can price very differently. If your house is already due for seismic work, doing both at once is cheaper than doing them a year apart.
All four still need a header or beam if the wall is bearing. The span is what drives the cost, which is why option two so often wins.
If the goal is a working kitchen and not just a bigger hole, settle the plan first — our kitchen layout guide covers the clearances that decide where the island and aisles land.
Before anything structural, someone should find out what is living inside that wall. Electrical is the easy one — circuits get rerouted. Ducts are usually workable.
Plumbing is the expensive surprise. Drains and vents need slope and a straight run up through the roof. If the wall you want gone carries the vent stack for the bathroom above, rerouting it means opening a ceiling, finding another wall to run it in, and doing it in the right order. On more than a few jobs, moving the plumbing costs more than the beam.
Removing or altering a bearing wall is structural work, so it takes a permit — every city, every time. Most Bay Area building departments want stamped calculations covering the beam, the posts, the footing and the bracing.
The framing gets inspected before anything is covered, which is the point: the inspection is the record that the beam and its connections are what the calculations called for. Keep the finaled permit in your file — when you sell, it is the difference between a documented remodel and an unpermitted one you have to disclose.
On schedule: the beam itself is usually a few days of work. What sets the calendar is the engineering and permit time before it, and the drywall, flooring and paint after it.
We do not put a number on a wall before seeing it, because five things move the price far more than the size of the room:
Two quotes for the same room can be thousands apart because one priced the footing and the bracing and the other did not. When you compare bids, compare those line items first.
Look up at which way the joists run. Look down in the crawlspace for a post on the same line. Then have someone confirm it before you plan a kitchen around the answer.
Budget for the whole load path and the bracing, not just the beam — that is where the difference between quotes usually hides.
Golden Ridge Construction frames beams, posts and footings for wall removals across the Bay Area, and works with the engineers who size them. Send us a photo of the room and one of the crawlspace, and we can usually tell you what you are dealing with.
There is no honest single number, because the price is set by the span, what sits above the wall, whether the beam is dropped or flush, whether the posts land on an existing footing, and what replacement bracing the engineer calls for — plus any plumbing or wiring inside the wall. Two quotes for the same room can differ by thousands because one priced the footing and the bracing and the other did not, so compare those line items before comparing totals.
Usually yes. The four common versions are taking the wall out entirely with a beam across the full span, leaving short walls at each end to shorten the span, cutting a counter-height pass-through, or dropping it to a half wall. All four need a header or beam if the wall is load-bearing. The wide opening with short returns is often the best value, because the returns shorten the beam span and frequently carry the earthquake bracing.
Three clues cover most cases. Look at the direction of the ceiling or floor joists above — if they run perpendicular to the wall, it is probably carrying them; parallel usually means it is not. Check whether another wall sits directly above it on the floor above. And look in the crawlspace for a post or girder lining up underneath. Exterior walls are almost always bearing. These clues point rather than prove: a house that has been remodeled before may have had its loads moved, so the wall should be confirmed by opening the ceiling or by an engineer reviewing the whole load path.
This is not a DIY job. The wall has to be shored temporarily while it is out, the beam has to be sized for the span and everything above it, and the posts need a continuous path down to a footing. It also needs a permit and, in most Bay Area cities, stamped engineering. Getting it wrong shows up as sagging floors, cracked drywall and doors that stop closing upstairs — and it becomes a disclosure problem when you sell.
Yes. Altering or removing a bearing wall is structural work and requires a building permit in every California jurisdiction. Most Bay Area building departments also require stamped calculations for the beam, posts, footings and any replacement bracing, and the framing is inspected before it is covered. Skipping the permit creates a disclosure issue at resale and can complicate insurance claims.
A dropped beam sits below the ceiling with the joists resting on top of it — simpler, faster and cheaper, but visible. A flush beam sits up inside the floor framing with each joist cut and hung off it on hangers, so the ceiling stays flat — more labor, more connections, often a deeper or steel beam, and more disturbance to the floor above. Under an 8-foot ceiling, a dropped beam noticeably reduces the sense of openness; at 9 or 10 feet it usually looks intentional.
In practice, yes for a bearing wall. The engineer sizes the beam for the span and the loads above it, specifies the posts and footings, and works out what replaces the wall's earthquake bracing. In high seismic areas — which covers most of the Bay Area — that bracing question is not optional, and the building department will ask for the calculations.
Wiring is usually straightforward to reroute, and ducts are generally workable. Plumbing is the expensive one, because drains and vents need slope and a path up through the roof. If the wall carries the vent stack for a bathroom above, rerouting it can mean opening another ceiling and finding a new wall to run it in — on some jobs that costs more than the beam itself. Find out what is in the wall before the structural plan is finished.
Often yes, and it can be simpler than in an older stick-framed house, because trusses span wall to wall and most interior walls under them carry nothing. The exception is a girder truss, which concentrates load onto a specific wall or post. Never assume from the truss type alone — have the specific wall checked.
The structural work itself is usually a few days: shore the ceiling, take out the wall, set the beam and posts, build the footing if one is needed. The calendar is set by what surrounds it — engineering and permit review before, and drywall, flooring, paint and any plumbing or electrical rerouting after. Plan in weeks, not days, for the whole sequence.
