Chicago is not a sprawl market — new construction means infill lots in Bridgeport, teardown-rebuild three-flats in West Ridge, or ADU additions where zoning allows. New construction loans in Chicago require lenders who understand city permit cadence, union labor markets, and winter concrete schedules.
What gets built (and funded) in 2026
- Teardown → three-flat: Popular in corridors where land value exceeds rehab economics on existing brick.
- Two-flat + rear ADU: Emerging where Affordable Requirements Ordinance (ARO) and ADU pilots intersect — verify zoning before you option the lot.
- SFR custom: Less common inside city limits; collar counties see more horizontal builds.
Construction loan structure
| Item | Range |
|---|---|
| Rate | 10%–13.5% interest-only during build |
| LTC | Up to 85% of land + vertical costs with presale or lease-up plan |
| Term | 12–18 months + extension options |
| Draws | Foundation, framing, MEP rough, drywall, CO |
| GC requirement | Licensed, insured, resume of Chicago work |
Permits and politics — budget real time
Chicago Department of Buildings inspections can add 4–8 weeks to naive timelines. Funded draws align to:
- Foundation/sign-off
- Structural/framing
- Rough mechanicals
- Drywall/finish
- Certificate of occupancy
Investors who treat Chicago like a Texas subdivision schedule get crushed on carry.
Worked scenario: South Shore infill duplex
Lot acquisition $95,000 + vertical $285,000 for a modern two-unit (each 1,100 sf). Presold one unit at $310,000 prior to CO. Construction loan $323,000 (85% LTC); interest carry 11 months; exit via unit sales and DSCR on retained unit.
Chicago zoning realities for builders
Before you close on a lot, confirm:
- RS-3 / RT-4 zoning — common for two-flat and three-flat entitlements
- ARO triggers — Affordable Requirements Ordinance may apply on larger developments; legal review required
- ADU pilot areas — rear coach houses and basement units have expanded pathways in select wards (ADU guide)
- Demolition delay — orange-rated structures can trigger 90-day holds; budget carry
Unlike collar-county builds, Chicago vertical construction faces aldermanic scrutiny — community meetings add calendar risk.
Two-flat teardown economics (2026)
When land exceeds rehab value, teardown-rebuild wins:
| Item | Example (Northwest side) |
|---|---|
| Land / teardown | $180,000 |
| Vertical (new 3-flat) | $520,000 |
| Total | $700,000 |
| Stabilized value | $950,000–$1.05M |
| Per-door rent (new) | $1,800–$2,100 |
Construction loan at 82% LTC keeps equity demand manageable; presale or pre-lease one unit before CO to satisfy exit lender.
Winter build schedule — non-negotiable in Chicago
Concrete pours below 40°F need blankets and additives. Roofing slows in November. Smart sponsors:
- Pour foundations by mid-October or wait until April
- Order long-lead mechanicals in framing phase
- Build 2-month weather contingency into interest reserve

FAQ
Do you fund condo deconversion construction?
Case-by-case — legal and HOA complexity require upfront review.
Is modular construction eligible?
Yes with approved manufacturers and Chicago inspection path documented.
Do you fund Chicago ADU-only projects?
Rear ADU and basement conversion loans are smaller checks — often better suited to HELOC/second or personal+credit line stacks. Ground-up ADU with full permits may qualify if bundled with primary unit renovation.
Cost per square foot reality (2026 Chicago)
| Build type | All-in $/sf (vertical) |
|---|---|
| Standard 2-flat renovation | $120–$180/sf |
| New vertical 3-flat | $200–$280/sf |
| High-spec Lincoln-adjacent | $300+/sf |
Material and labor inflation stabilized but skilled trades remain tight — lock GC pricing before you close land.
Interest reserve and carry
On a $700K construction loan at 11.5% IO:
- Monthly interest: ~$6,700
- 14-month build + lease: ~$94K interest reserve
Sponsors who under-reserve get squeezed at month ten — we stress-test reserves in underwriting so you finish the building, not fire-sale the half-built frame.
Comparison: 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 if Chicago | No |
| Exit | DSCR per door | DSCR or resale |
Many investors build new in Will/Joliet and rehab brick in Chicago — we fund both.
GC selection in Chicago — lender perspective
We look for:
- Chicago DOB permit history — not only suburban
- Bonded and insured at limits matching project size
- References on 2–4 unit vertical — not only SFR
- Transparent subcontractor bids — no post-close change orders without approval
The cheapest GC is rarely the fastest to CO — carry kills deals more than bid spread.
Environmental and soil surprises
Infill lots may hide underground tank or fill soil issues. Phase I environmental on commercial-adjacent lots; soil borings on vacant land before you close — construction lenders do not fund remediation surprises mid-build.
