The split-level lighting problem: two roof heights, one house
A split-level does not give you one roofline to follow. It gives you two, sometimes three, stacked at different heights across the same facade. That single fact drives almost every decision on the design.
Two houses in one facade
A classic split-level puts the garage and a lower living level on one side of the house and a taller two-story section on the other, connected by a short flight of interior stairs. From the street, that means two different roofline heights sitting next to each other.
Where a ranch gives us one line and a colonial gives us two clean symmetrical stories, a split-level gives us an asymmetrical jump. The lighting design has to acknowledge that jump instead of trying to smooth it into a single continuous run.
This is not a harder install, just a different measuring exercise. Each roofline height gets its own run of track, sized to that section's actual linear footage rather than assumed to match the section next to it.
Split-levels are common enough across older suburban developments in this region that we have measured plenty of them, but no two are identical. Builders varied garage placement, entry landing depth and the degree of stagger enough from one development to the next that each house still gets walked individually before a plan is set.
Where the levels meet
The point where the lower and upper rooflines meet, often above the garage, is the detail that decides whether a split-level lighting job looks intentional or accidental. We generally run both lines fully to that meeting point rather than stopping short, so the eye reads a continuous descent rather than a gap.
On homes where the garage sits forward of the main house, that garage roofline sometimes gets its own separate control zone, since it is physically and visually the most distinct section of the facade.
The transition detail also affects how much total track a job needs. A house where the two levels meet cleanly at a single point requires less connecting run than one where the levels step down in two or three smaller increments across the front of the house, which we measure precisely on-site rather than estimating from a photo.
What zones a split-level typically needs
Beyond the two or three roof heights, most split-levels we quote add a front entry zone, since the door is frequently tucked at the mid-level landing between the upper and lower sections and benefits from its own accent run.
A rear deck, common on split-levels built into a sloped lot, is a separate landscape lighting conversation rather than part of the roofline package, though many owners do both projects together.
Bay windows, when present on the taller section of a split-level, are usually left unlit on their own, since the upper roofline run above them already provides enough visual anchor for that part of the facade without an additional dedicated fixture.

Sloped lots and split-levels
Split-levels are frequently built into a sloped lot, which is part of why the roof heights stagger in the first place. That slope also changes the sightline from the street. A run that looks balanced from directly in front of the house can look uneven from an angle further down a hill.
We walk that sightline during the on-site consultation rather than guessing from a single photo, and the render mock-up is built from the angle you actually see the house from most, usually your own driveway or the street below.
A retaining wall at the base of a sloped split-level lot, common where the driveway cuts down toward the garage level, is occasionally added as a small landscape lighting accent alongside the main roofline package, though it is evaluated separately rather than assumed as part of the base quote.
Running scenes across two heights
Because the lower and upper roofline zones are wired independently on a split-level, they can also be controlled independently once the system is running. Some owners run the same scene across both heights so the house reads as one unit, while others let the upper story hold a brighter or more saturated version of a color and the lower garage line stay more subdued.
That flexibility is not unique to split-levels, every zoned install can do it, but it matters more here than on a single-height ranch, since a split-level already presents the house in two visual planes before any lighting is added. The design either leans into that layering or works to minimize it, and both are valid choices depending on what the homeowner wants the house to say from the street.
We talk through both approaches during the on-site visit, usually settling the question once the render mock-up shows both options side by side on the actual facade.
What we skip
We do not try to force a split-level's two roof heights into matching visual weight if the sections themselves are genuinely different sizes. A short garage-side run next to a longer two-story run is correct, not a mistake to fix. Matching them artificially would mean adding track where the roofline does not exist.
Smaller secondary windows at the mid-level landing are usually left unlit, since a short accent run at the entry already carries that part of the facade.
Getting a split-level quoted
Because split-level rooflines vary more in shape than a single-story or symmetrical two-story home, the free on-site visit and render mock-up carry more weight in the planning than they do for a simpler layout. You will see both roof heights traced on your actual house within 48 hours.
