You bought a split level for the lot size and the price, then spent months tripping over the awkward half staircase between the entry and living room. The kitchen feels boxed in. The lower level stays dark enough that you avoid it after 4 p.m. If that sounds familiar, you’re not dealing with a bad house, just a layout built fast in the 1950s through 1970s that never caught up with how people live now.
A Split Level Home Remodel doesn’t mean tearing the house down. It means fixing what makes split levels feel choppy and dark, while keeping the bones that made them affordable. At San Diego Home Remodeling, we’ve had this exact conversation with homeowners across the county.
What Is a Split Level Home?
A split level home staggers its floors by half stories instead of stacking them into one continuous set of floors like a traditional two-story house. You typically enter on a mid-level landing, then take a short flight of stairs up to the bedrooms and another short flight down to a lower level, often the garage, a den, or a rec room.
Builders used this layout to fit more usable square footage on smaller, sloped lots without the cost of a full second story. It worked well for the postwar housing boom, and it still shows up constantly in older San Diego neighborhoods like Clairemont, Allied Gardens, and parts of La Mesa. The tradeoff is a home made of smaller, boxed-off rooms connected by short staircases instead of one open, easy-to-navigate floor plan.
The Pros and Cons of Split-Level Homes
Split levels get a bad reputation online, but the format has real strengths worth naming before you plan a split level house remodel. On the plus side, you typically get more square footage per dollar than a comparable ranch or two-story home on the same lot, the half-level separation gives some natural noise buffering between living and sleeping areas, and the structure itself is usually sound, since these homes were built during a period when lumber and labor were both reasonably priced and code enforcement was consistent.
The downsides are the ones you are probably already living with. Ceilings on the entry level tend to run low. Natural light struggles to reach the lower level. The choppy floor plan blocks sightlines between rooms, which makes even a decently sized home feel cramped. None of these are structural failures. They are design decisions from fifty years ago that a focused remodel can correct without changing your home’s footprint or your property tax basis.
The 4 Biggest Problems With Split-Level Layouts
Before jumping into fixes, it helps to name the specific problems, because a generic “open the space up” plan wastes money if it does not target what is actually bothering you.
- Dark lower level. Half-buried by design, the lower level often relies on one or two small windows, which makes it feel more like a basement than real living space, even when the square footage is there.
- Choppy floor plan. Full walls between the kitchen, dining, and living areas were standard when these homes were built. Today they block both light and conversation, which is why so many split level owners feel isolated even with family in the next room.
- Narrow, steep stairs. Original split level staircases were built to code minimums for the era, which means they are steeper and narrower than what most people find comfortable now, especially with kids or aging parents in the house.
- Cramped entry. The classic split level entry is a small landing squeezed between two staircases, with barely enough room to greet a guest, let alone add a bench or storage.

Split-Level Remodel Solutions That Actually Work
Each of these problems has a specific fix. Here is what we recommend based on projects we have completed across San Diego County, along with realistic cost ranges and permit considerations specific to this region.
For the dark lower level: Finishing the space properly with recessed lighting, added insulation, and either a larger window or a well-designed light well changes it from storage overflow into a real family room, home office, or guest suite. In San Diego, this typically runs $20,000 to $45,000 depending on whether plumbing is involved. Because the lower level often sits below grade, our team checks moisture barriers and drainage before any framing starts, which is a step we have seen skipped on other split entry house remodel projects, leading to mold issues within a year.
For the choppy floor plan: Removing a non-load-bearing wall between the kitchen and living room is one of the highest-impact, most requested changes we handle. Cost runs $8,000 to $18,000 for a straightforward removal with finishing. If the wall is load-bearing, which is common in the staggered floor design of a split level, you will need a support beam and a structural engineer’s sign-off, pushing cost to $15,000 to $30,000. Never assume a wall is safe to remove just because it looks non-structural. We have corrected two projects this year where a previous contractor missed a load-bearing wall in a split level’s staggered framing.
For narrow, steep stairs: Widening the staircase by even four to six inches and swapping a solid wall for an open railing lets light travel between levels and makes the stairs noticeably safer. Budget $6,000 to $14,000 depending on whether the stair structure itself needs rebuilding or just the railings and finishes.
For the cramped entry: A redesigned entry with a covered porch, wider door, and better exterior lighting solves both the first impression problem and the tight interior landing. This runs $10,000 to $25,000 and is one of the better return-on-investment moves for resale, since curb appeal is the first thing a buyer judges.
If your kitchen needs more than a wall removal, an island or breakfast nook added through a small bump-out is worth exploring through our San Diego Whole Home Remodeling service, since kitchen and layout changes on a split level usually touch adjoining rooms and work better planned together rather than piecemeal.
Real Project Spotlight
Earlier this year, we completed a Split Level Home Remodel for a family in a 1968 split level near Allied Gardens. Their two biggest complaints were a lower level that felt unusable and a kitchen completely walled off from the living room. We removed a non-load-bearing wall between the kitchen and living area, widened the main staircase from 32 inches to 38 inches with an open cable railing, and finished the lower level into a home office and guest bedroom with a new egress window for natural light and safety compliance.
The full project took nine weeks, including permit review, and landed at just under $52,000. The biggest surprise for the homeowners was not the cost. It was how much brighter the main level felt after the staircase opened up, since light from the vaulted entry now reaches all the way into what used to be a dark hallway. That single change is why we recommend evaluating the staircase early in any split level house remodel, even when it was not the homeowner’s original priority.
Split-Level Remodel Cost Breakdown
Costs vary with scope, but here is a realistic range for San Diego County based on current labor and material pricing:
- Cosmetic updates (paint, flooring, lighting, railings): $5,000 to $15,000
- Wall removal or kitchen bump-out: $8,000 to $25,000
- Finished lower level (office, family room, or guest suite): $20,000 to $50,000
- Full second-story addition or whole-home reconfiguration: $100,000 or more
San Diego permit fees typically add $1,500 to $4,000 depending on scope, and load-bearing wall changes require a structural engineer’s stamp, which usually runs $800 to $2,000 on its own. Always get itemized quotes from at least three licensed contractors so you can compare labor, materials, and permit costs separately instead of one bundled number.
Before You Start Your Remodel
Check your local building codes before you commit to any layout change. Many split entry house remodel projects, especially ones touching load-bearing walls or the roofline, need permits and inspections through the City of San Diego or your local jurisdiction. Skipping this step can create real problems if you sell the home later and the buyer’s inspector flags unpermitted work.
Set your budget with a 10 to 20 percent buffer built in. Homes from this era often hide outdated wiring, undersized insulation, or plumbing that does not match current code once walls come down. Work with a contractor who has specific split level experience, since the staggered framing and half-level transitions behave differently than a single-story or standard two-story remodel.
Common Mistakes to Avoid
The mistake we see most often is a homeowner removing a wall without confirming whether it carries structural load, which on a split level is more common than people expect because of how the staggered floors distribute weight. Always get a structural engineer involved before any wall comes down.
Another frequent issue is updating one level beautifully while leaving the others mismatched, which makes the disconnect between floors feel worse rather than better. We recommend planning flooring and paint tones across the whole home from the start, even if you are phasing the work over a year or two.
Skimping on lighting is the third common error. Split levels already fight against natural light in the lower level and stairwells, so cutting the lighting budget leaves rooms feeling dim even after a full remodel.

Frequently Asked Questions
Is it worth remodeling a split level home?Â
Yes, in most cases. Split levels typically sit on larger lots than comparable modern builds and have a solid structural foundation to work with, so a well-planned Split Level Home Remodel raises both daily comfort and resale value.
What is the cheapest way to update a split level home?Â
Cosmetic changes such as new flooring, paint, updated stair railings, and better lighting fixtures cost the least while still making a noticeable difference in how connected the home feels.
Can you remove interior walls in a split level home?Â
Some walls can come out safely, but many carry structural weight because of the staggered floor design. Always have a structural engineer or licensed contractor confirm load-bearing status before removing anything.
How long does a typical split entry house remodel take?Â
Smaller projects like flooring, railings, or window updates take two to four weeks. Larger projects, such as finishing a lower level or adding a second story, typically run two to four months depending on permits and contractor scheduling.
Do split level remodels increase resale value in San Diego?Â
Yes, in most local markets. Buyers respond well to open sightlines, updated staircases, and finished lower levels, all of which are common outcomes of a well-executed split level house remodel.
