Chicago Infill and Teardown-Rebuild Economics 2026
By Jason Taken · Principal, Jaken Finance Group
Chicago infill and teardown-rebuild economics for investors — lot acquisition, DOB permits, cost per sf, construction loan structure, and DSCR exits. 2026 guide.
Chicago investors face a recurring question on every RT-4 zoned lot: rehab the existing brick or tear down and rebuild? In 2026, teardown-rebuild economics win in corridors where land value exceeds rehab value but new vertical rental stock commands premium rents.
This post walks through lot acquisition, demolition, construction loan structure, DOB permit reality, and exit math — the companion to our new construction loans Chicago hub.
When teardown beats rehab
Run this comparison before you option a lot:
| Input | Rehab existing 2-flat | Teardown → new 3-flat |
|---|---|---|
| Land / building basis | $320K (distressed brick) | $180K land + $45K demo |
| Vertical cost | $165K rehab | $520K new build |
| Total | $485K | $745K |
| Stabilized value | $620K–$680K | $950K–$1.05M |
| Per-door rent (new) | $1,500–$1,750 | $1,800–$2,100 |
| Timeline | 6–9 months | 14–18 months |
| Product | Fix and flip or BRRRR | Construction loan — up to 100% LTC |
Teardown wins when per-door rent on new construction clears DSCR at higher basis — and when existing brick needs $200K+ in structural, plumbing, and envelope work that approaches new-build cost without new-build efficiency.
Cost per square foot — 2026 Chicago reality
| Build type | All-in $/sf (vertical) |
|---|---|
| Standard 2-flat gut rehab | $120–$180/sf |
| New vertical 3-flat | $200–$280/sf |
| High-spec Lincoln-adjacent | $300+/sf |
| Rear ADU addition (permitted) | $250–$350/sf |
Material costs stabilized mid-2026, but skilled trade availability remains the bottleneck — lock GC pricing before land close.
Construction loan structure
Jaken new construction parameters for Chicago infill:
| Parameter | Range |
|---|---|
| Rate | 8.99%–13.5% interest-only during build |
| LTC | Up to 100% on qualified files (land + vertical) |
| Term | 12–18 months + extensions |
| Draws | Foundation, framing, MEP rough, drywall, CO |
| Close | 10–14 business days with complete file |
Interest reserve example: $700K loan @ 11.5% for 14 months = ~$94K carry. Under-reserve at month ten and you fire-sale the half-built frame.
DOB permit sequence — budget real time
Chicago Department of Buildings is not a suburban plan review office:
- Demolition permit — orange-rated structures trigger 90-day delay
- Foundation — winter pours below 40°F need blankets and additives
- Structural/framing — union labor markets affect scheduling
- Rough MEP — long-lead mechanicals ordered at framing
- Drywall/finish — inspection backlog in peak season
- Certificate of occupancy — final sign-off before DSCR or sale
Smart sponsors pour foundations by mid-October or wait until April. Roofing slows in November.
Zoning checklist before land close
- RS-3 / RT-4 — confirm multifamily entitlement
- ARO triggers — Affordable Requirements Ordinance on larger developments
- ADU pilot — rear coach houses in select wards (ADU guide)
- Aldermanic review — community meetings add calendar risk vs collar county builds
- Environmental — Phase I on commercial-adjacent lots; soil borings on vacant land
Worked scenario: West Ridge teardown → 3-flat
| Line item | Amount |
|---|---|
| Land acquisition | $175,000 |
| Demolition + permits | $48,000 |
| Vertical (new 3-flat, 3,200 sf) | $512,000 |
| Total project cost | $735,000 |
| Construction loan (100% LTC) | $735,000 @ 11% IO |
| Build + lease timeline | 16 months |
| Interest carry | ~$91,500 |
| Stabilized gross rent | $5,400/mo ($64,800/yr) |
| As-completed value | $985,000 |
| DSCR refi (85% LTV rate-and-term) | $837,250 @ 6.75% · 1.07 DSCR |
Alternative exit: presold one unit at $325K before CO to reduce construction loan balance.
Spec vs pre-sold exit
| Exit | Pros | Cons |
|---|---|---|
| Spec hold (DSCR) | Recycle capital via refi | Carry through lease-up |
| Pre-sold unit | Reduces loan balance at CO | Buyer financing contingency |
| Full building sale | Clean exit | Developer margin compressed |
Many Chicago infill sponsors pre-lease one door and DSCR the rest — hybrid exit that satisfies construction lender exit requirement.
Chicago infill vs Will County horizontal
| Chicago infill 3-flat | Will County SFR new | |
|---|---|---|
| Permits | DOB, slower | Municipal, faster |
| Product | Vertical rental | SFR / duplex |
| RLTO | Yes | No |
| Labor | Union-influenced | More flexible |
Many investors build new in Will/Joliet and rehab brick in Chicago — we fund both.
