How to Build a Whole-House Renovation Budget (With Split-Level Numbers)

Hate to Love the Split · October 26, 2026

A home renovation budget is the one document that decides whether a split-level makeover ends with a finished kitchen or with a half-painted hallway and a drawer full of receipts you stopped adding up. I have made every version of that mistake, so this is the budget method I use now, with example numbers scaled for a 1970s Minneapolis split-level like this one.

Nothing here is a quote. Prices move, and Twin Cities labor is not Des Moines labor. The point is the structure, because the structure is what keeps you honest.

Start with the house, not the Pinterest board

A split-level has a particular shape of cost. The upper level is cheap to change: paint, trim, flooring, lights. The lower level is where money hides: egress windows, moisture, the furnace closet that eats a third of the room, and the half-bath somebody added in 1988 without a permit. The entry landing and the stairs touch every other project, so they get touched twice if you do not plan for it.

So before any line item, walk the house with a notebook and write down three columns: what is broken, what is ugly, and what is both. Broken-and-ugly goes first. Broken-but-hidden goes second, even though it is no fun. Ugly-but-working goes last, and most of it never happens, which is fine.

If you are in the "ugly" column on the hallway walls, the wallpaper removal and Gardz post is the cheapest project on this site and it changes the whole feel of the upper level.

The budget template

Here is the skeleton. Every project gets a row, and every row gets the same five numbers.

  1. Materials estimate. Priced from actual carts, not from memory.
  2. Labor estimate. Zero if you are doing it, or a real quote. "A friend will help" is zero until the friend cancels.
  3. Permits and fees. Minneapolis electrical, plumbing and mechanical work needs permits. They are not expensive. Skipping them is.
  4. Tools you do not own. Renting a floor sander or a drywall lift costs money. Buying a tile saw you will use once is a budget line, not a treat.
  5. Contingency. Twenty percent of the first four numbers, every single row.

Total each row. Then total the rows. Then look at the number and take something off the list, because it is always more than you thought.

Example: a split-level, three projects, one year

These are example figures for a plan that touches the kitchen, the lower-level family room and the entry. They are deliberately mid-range for the Twin Cities. Your quotes will differ. The proportions will not differ much.

Kitchen refresh (not a gut). New counters, a sink and faucet, painted cabinets, new hardware, one new light, backsplash tile. Materials around 6,500. Labor, if you hire the counter install and the electrical, around 2,800. Permit for the electrical, under 200. Tools, a tile saw rental and a decent paint sprayer, about 350. Contingency on all of that, about 2,000. Row total near 11,800.

Lower-level family room. Moisture check and sealing, new LVP flooring over the slab, drop ceiling out and drywall ceiling in, recessed lights, paint. Materials around 5,200. Labor for the drywall ceiling and the electrical, around 3,400. Permits, about 250. Tools, a drywall lift rental, under 100. Contingency, about 1,800. Row total near 10,750.

Entry and stairs. New railing, stair treads refinished, tile at the landing, a bigger light, paint. Materials around 2,100. Labor if you hire the railing, about 900. No permit. Tools, a sander rental, about 80. Contingency, about 600. Row total near 3,700.

Plan total just over 26,000. That is a lot of money. It is also, in my experience, the number you would have spent anyway, except that without the budget you would have spent it in a different order and been surprised at the end.

The lines that always get missed

Dumpsters and disposal. A drop ceiling, old carpet and a kitchen counter fill a 10-yard dumpster fast. Budget 400 to 600 per project phase.

Paint, again. Every project touches an adjacent surface. The family room ceiling means the stair wall gets repainted. Add a paint line to every row even when paint is not the project.

Fasteners, caulk, shims and the second trip. Ten percent of materials, and I am being generous to myself.

Food. If the kitchen is down for three weeks, you will eat out. That is a real renovation cost and it belongs in the row.

Living with it. Dust control, a temporary cooking setup, a storage unit if the basement is the staging area. Small lines, real money.

Where the 20 percent goes

People treat contingency as a slush fund. It is not. It is the money for the things you could not see. In a split-level that usually means one of these: the subfloor at the lower-level bathroom is soft; the panel is full and the kitchen circuit needs a new run; the stair stringers are notched badly enough that the railing install turns into a carpentry job; or the moisture test fails and the flooring waits a season.

If the contingency is still there at the end, it rolls to the next project. It never rolls into a nicer faucet mid-project. That rule has saved me more than any coupon.

Sequencing is a budget decision

Order matters because of what touches what. Do moisture and mechanical first, then anything in the walls and ceilings, then floors, then paint, then the pretty parts. That is boring, and it is also why the family room should come before the kitchen if there is any chance the lower level is damp. Fixing the floor after the paint is a double spend.

The tongue-and-groove ceiling comparison is a good example of a project that looks like decoration but belongs in the "ceilings" phase, before lights and before paint.

Tracking it without a spreadsheet degree

One tab, one row per project, the five numbers, plus a column called Actual that you update every time you spend. Receipts go in a shoebox, photographed, and added weekly. Not daily. Weekly is sustainable. Daily turns into never.

Every month, compare Actual to Estimate and write one sentence about why they differ. That sentence is the real education. By the third project you will be estimating within ten percent, which is the whole game.

Resale, honestly

If part of the reason is resale, look at the industry cost-versus-value data before you decide what to do. The Cost vs. Value report tracks what common projects return at sale, region by region, and the pattern for the upper Midwest is stable: exterior work and modest kitchen updates hold value, big additions and luxury baths do not. A split-level with a dry, finished lower level and a clean kitchen sells. One with a marble island and a damp family room does not.

The short version

Walk the house. Make the three columns. Give every project five numbers. Add 20 percent to each row and do not touch it. Sequence from wet to dry, from inside the walls to the surface. Track weekly. Expect to cut the list.

That is the whole method. The example above is a model, and your numbers will be your numbers. If you want a small, low-risk place to start, the IKEA Pax closet makeover is the kind of project where the budget practice pays off before the stakes get high.
