Multifamily siding replacement is budgeted per square foot and per unit, not as one flat number — and the only number that means anything for your building is the one a scoped, comparable bid produces. As a sanity-check anchor, the Remodeling/JLC Cost vs. Value 2024 report priced a single-family fiber-cement siding replacement (about 1,250 sq ft, including trim) in the Minneapolis region in the low-$20,000s, and a vinyl replacement somewhat lower; on a per-square-foot basis that lands roughly in the mid-teens per foot installed for fiber cement. Multifamily pricing typically runs higher per foot than that single-family benchmark because of access, scale, and code requirements — so treat any figure here as a planning range, not a quote.

This page breaks the cost down by material, shows how to model it per unit, and names the hidden costs that turn a low bid into a change-order surprise.
What does multifamily siding cost per square foot in Minnesota?
Per-square-foot cost is driven mostly by material, with vinyl cheapest and steel/fiber cement at the top. The defensible planning ranges below are bands, not promises — the Cost vs. Value fiber-cement benchmark above sits inside the fiber-cement band, and multifamily installed pricing often lands at or above the top of each band because of access, scale, and code-required envelope work. Confirm every figure with live quotes before you build a budget on it.
| Material | Planning range ($/sq ft installed) | Typical lifespan | Why the price |
|---|---|---|---|
| Vinyl | low end of the spread | 20–30 yr | Cheapest material, fast install |
| Engineered wood (LP SmartSide) | mid band | 40–50 yr | Value + cold/hail performance |
| Fiber cement (James Hardie) | upper-mid band | 50+ yr | Heavier, slower, specialized install |
| Steel | top of the band | 50+ yr | Durability, specialized install |
The dollar spread across these materials is wide enough — and so dependent on building height, access, and how much wall work the tear-off reveals — that a single per-foot number would mislead more than it helps. Lead with the relative ranking (vinyl cheapest, fiber cement and steel highest) and let live bids set the actual numbers. Material is only half the cost story; the wall-system work and access drive the rest. See how long siding lasts, fiber cement, and engineered wood.
How do you budget siding per unit?
Budget per unit by estimating total siding square footage for the building, multiplying by the installed per-square-foot rate for your material, adding the non-material costs (tear-off, rot allowance, flashing, trim, disposal, access), then dividing by the number of units. The per-unit number is what owners feel and what an assessment is built on, so it’s the figure boards should lead with.
A simplified path:
- Estimate wall area — total exterior siding square footage (not floor area).
- Apply installed $/sq ft — for the chosen material.
- Add non-material costs — tear-off, rot allowance, flashing, trim, disposal, access equipment.
- Divide by units — to get a per-unit figure.
- Subtract reserves — to get the per-unit assessment (see special assessment explained).
Two buildings with the same unit count can have very different per-unit costs if one has more exterior wall area per unit (e.g., townhomes vs. a stacked condo).
What hidden costs blow up the budget?
The costs that surprise boards aren’t the siding — they’re tear-off, hidden rot and sheathing repair, flashing, trim, disposal, and access equipment. A bid that quotes only material and labor looks cheaper precisely because it left these out, and they reappear as change orders once the wall is open. Hidden rot is the biggest single risk because it’s invisible until tear-off.
The line items a complete budget must include:
- Tear-off and disposal of the old siding
- Sheathing / rot-repair allowance (the most common surprise)
- Water-resistive barrier and flashing (including code-required kick-out flashing)
- Trim and transitions
- Access equipment (lifts, scaffolding for taller buildings)
- Resident-disruption / communication on occupied buildings
- Permits and inspections
A “low bid” missing these isn’t cheaper — it’s less complete. Making every vendor price the same list is the job of the Replacement Scope Map.
Why do two bids for the same building differ so much?
Two bids differ mostly because they’re quoting different scopes, not different prices for the same work — one includes a rot allowance, full flashing, and disposal, while the other quietly omits them. Until the scope is standardized, comparing the bottom-line numbers is meaningless; the cheaper bid is often just the one that left more out.
This is the central problem in multifamily siding procurement and the reason scope comes before price. When every vendor bids the same defined project — same material, same allowances, same flashing, same access plan — the numbers finally become comparable and the board can defend its choice. See comparing siding bids line by line and the Scope Map.
How does per-unit cost feed the funding decision?
The per-unit cost is the input to the whole funding decision: subtract reserves to get the per-unit assessment, and if that number is too high for a lump sum, that’s the signal to phase the work or use a loan so owners pay over time. Cost, reserves, and funding mechanism are one connected calculation, not three separate ones.
So the practical sequence is: scope the project, get a real per-unit cost, compare it to reserves, and then choose the funding path that makes the per-owner number manageable. See reserves vs. special assessment vs. loan and the funding pillar.
FAQ
Q: How much does it cost to re-side an apartment or condo building in Minnesota? It’s budgeted per square foot and per unit, and the real number comes from a scoped bid. For a sanity check, the Remodeling/JLC Cost vs. Value 2024 report put a single-family fiber-cement re-side in the Minneapolis region in the low-$20,000s for about 1,250 sq ft; multifamily per-foot pricing usually runs higher because of access and scale. Boards often use a rough $5,000-per-unit anchor to start the assessment conversation, but that’s a placeholder until you have a scoped cost. The biggest swing factors are material, building access, hidden rot, and whether trim, flashing, and disposal are in the bid.
Q: Which siding material is cheapest for multifamily? Vinyl is cheapest up front but has the shortest Minnesota life (20–30 years) and the weakest cold/hail performance. Engineered wood, fiber cement, and steel cost more but last 40–50+ years and handle the climate far better, so the lowest upfront cost isn’t always the lowest lifecycle cost.
Q: Why is one bid so much lower than the others? Usually because it’s quoting a smaller scope — leaving out a rot allowance, full flashing, disposal, or access — not because it’s a better deal. Until every vendor bids the same defined project, the bottom-line numbers aren’t comparable. Standardize the scope first, then compare.
Q: What hidden costs should we budget for? Tear-off and disposal, a sheathing/rot-repair allowance (the most common surprise), the water-resistive barrier and flashing including kick-out flashing, trim, access equipment, resident-communication on occupied buildings, and permits. A budget that omits these will be blown by change orders once the wall is open.
