Chicago Bungalow Renovation Cost: What Owners Actually Pay in 2026
Renovating a Chicago bungalow runs $30,000 to $400,000+ depending on how far you go — and no other Chicago house rewards going further like a bungalow does. Here's real 2026 pricing for every scope, the attic and basement math that can nearly double your living space without an addition, and the century-old surprises to budget for.
Chicago Bungalow Renovation: $30K–$400K+ by Scope
Renovating a Chicago bungalow costs $30,000–$400,000+ in 2026 depending on scope — with gut-level work running $100–$300 per square foot. The bungalow's superpower: an unfinished attic and a full basement mean you can nearly double your living space without ever building an addition.
- Cosmetic refresh: paint, refinished oak floors, fixtures, lighting. 4–8 weeks. $30K–$60K
- Kitchen & bath focus: the two rooms that date a bungalow most. 2–4 months. $60K–$140K
- Whole-bungalow mid-range: kitchen, baths, opened floor plan, select systems. 4–6 months. $150K–$250K
- Full gut + attic & basement buildout: down to studs, all-new systems, master suite upstairs. 6–9 months. $250K–$400K+
- The floor-plan move: opening the kitchen to the dining room runs $40K–$55K including the steel beam.
80,000 bungalows — and they all hide the same secret
Chicago has more than 80,000 bungalows, nearly all built between 1910 and 1940 in a brick arc through the Northwest and Southwest sides — the Bungalow Belt. Solid masonry, original oak floors, real millwork, art glass windows. And nearly all of them share the same layout problems: a closed-off galley kitchen, one dated bathroom, and small rooms chopped up by walls.
Here's the secret buyers miss: a bungalow's listed square footage is usually only half the house. The unfinished attic and full-height basement sitting above and below the main floor are the cheapest square footage you will ever add in Chicago — no foundation, no new roof, no zoning fight. That's why bungalow renovation math is different from any other house type in the city.
Assembly Squad has renovated bungalows across Portage Park, Jefferson Park, North Park, Albany Park, and Beverly as part of 500+ Chicago projects since 2013 — including 200+ bungalow kitchens. The numbers below are the ones we put in fixed-price proposals, not national averages. This guide is part of our Chicago home remodeling pricing series.
Renovate what you have — or unlock the whole house?
Every bungalow project starts with the same fork: update the main floor you live on, or go up and down and turn a 3-bedroom, 1-bath bungalow into something twice the size. Both are good projects — but they're different budgets, and it pays to decide before design starts.
Kitchen, bathroom, refinished floors, and — the most popular single move — opening the kitchen to the dining room with a steel beam. The house lives dramatically better without touching the attic or basement.

| Kitchen & bath focus — the two rooms that date a bungalow | $60,000–$140,000 | 2–4 mos |
| Whole-bungalow mid-range — kitchen, baths, opened plan, select systems | $150,000–$250,000 | 4–6 mos |
| Full gut + attic & basement buildout — studs out, all-new MEP, master suite up top | $250,000–$400,000+ | 6–9 mos |
Full-gut pricing follows our Chicago gut rehab cost guide — $100–$300/sq ft, with most complete transformations landing between $150,000 and $400,000.
Where the budget actually goes
| Line Item | 2026 Range | The Bungalow Wrinkle |
|---|---|---|
| Kitchen renovation | $35,000–$85,000 | Opening to the dining room: $40K–$55K with the beam |
| Bathroom renovation | $25,000–$85,000 | Most bungalows need a second bath — the attic is the answer |
| Attic master-suite conversion | $60,000–$150,000 | Bedroom, bath & closets in space you already own |
| Basement finishing | $50,000–$150,000 | Family room, office, guest suite below grade |
| Full MEP replacement — electrical, plumbing, HVAC | $75,000–$95,000 | Pre-1940 systems weren't built for modern loads |
The four moves that transform a bungalow
After 200+ bungalow kitchens and full-house transformations across the Bungalow Belt, nearly every great bungalow renovation is built from the same four moves — in this order:
- 1Open the main floorThe wall between kitchen and dining room is almost always load-bearing. A steel beam ($8,000–$15,000 installed, engineering included) opens the whole floor — the full kitchen-to-dining project runs $40,000–$55,000 and is the single most popular bungalow upgrade we build.
- 2Replace the systems while walls are openKnob-and-tube wiring, galvanized pipes, and a tired furnace all date from the Coolidge administration. Replacing MEP during the renovation — not after — means you never pay for demolition twice.
- 3Convert the atticA master suite with bath and real closets, $60,000–$150,000 depending on dormers and stairs. It's the bedroom and second bathroom the original floor plan never had — at a fraction of addition cost.
- 4Finish the basementFamily room, office, or guest suite at $50,000–$150,000 — see our basement finishing cost guide. Between attic and basement, a 1,400 sq ft bungalow becomes a 2,500+ sq ft home.
What the investment gives back
Bungalow renovations hold their value unusually well in Chicago — because the supply of well-renovated bungalows never catches up with demand. Period-appropriate kitchen renovations return 75–85% ROI, and updated bungalow kitchens sell 25–30% faster in Chicago's market. The trap to avoid: stripping the character. A modern update that loses the millwork and art glass returns 65–75% — keeping the character pays better.
"A bungalow is the only Chicago house where the cheapest square footage you can buy is already under your own roof. You don't build an addition — you unlock the attic and the basement."

What a 100-year-old bungalow is hiding
Every bungalow we open has at least one of these. Across 500+ projects, this is what actually turns up behind the plaster and under the floors — and what it costs to fix while the walls are already open:
| Hidden Cost | Typical Range | How Often We Find It |
|---|---|---|
| Knob-and-tube wiring removal | $8,000–$15,000 | Very common pre-1930 |
| Galvanized plumbing replacement | $12,000–$20,000 | Very common pre-1940 |
| Asbestos / lead remediation | $10,000–$25,000 | Common pre-1978 |
| Layered subfloors — up to four deep | $3,000–$8,000 | Common in kitchens |
| Foundation repairs | $10,000–$40,000 | Occasional |
Budget 15–25% on top, on any pre-1940 bungalow
On a North Park kitchen we opened last year, the floor hid four separate layers of flooring stacked over decades — invisible until demolition day. The difference between a smooth project and a stalled one is whether that money was planned from day one. Our fixed-price proposals price the known scope firmly and ring-fence the contingency separately — so a surprise under the floor becomes a line item, not a change-order fight.
Cost across the Bungalow Belt
The Bungalow Belt arcs from the Northwest Side around to the Southwest Side and Beverly. Renovation cost tracks finish expectations, permit complexity, and logistics — premium and historic-district areas run 15–25% more:
| Neighborhood | Gut Reno $/Sq Ft | What Moves the Number |
|---|---|---|
| Portage Park / Jefferson Park | $110–$200 | The heart of the Belt — our busiest bungalow zone |
| Norwood Park / Edison Park | $125–$225 | Larger lots, higher finish expectations |
| North Park / Albany Park | $110–$200 | Strong first-time-buyer demand keeps ROI high |
| Irving Park / Old Irving | $120–$225 | Mix of bungalows and larger vintage stock |
| Beverly / Morgan Park | $125–$250 | Historic districts — allow time for review |
| Garfield Ridge / Clearing | $100–$175 | The Belt's best value per square foot |
A real one: the North Park bungalow on W Agatite
First-time homeowners in North Park (60630) with a classic bungalow kitchen problem: solid house, great block, kitchen from another era. We ran a $65,000 fixed-price gut renovation — 3D design first, then full demolition down to the four-layer subfloor, complete plumbing and electrical replacement, new insulation and drywall, modern cabinets, stone countertops, and 8 recessed lights. Done in 7 weeks from design to final walkthrough. See the full project, every stage documented.

Bungalow renovation FAQ
How much does it cost to renovate a Chicago bungalow?
Renovating a Chicago bungalow costs $30,000–$60,000 for a cosmetic refresh, $60,000–$140,000 for a kitchen-and-bath focus, $150,000–$250,000 for a whole-bungalow mid-range renovation, and $250,000–$400,000+ for a full gut with attic and basement buildout — with gut-level work running $100–$300 per square foot depending on finishes and neighborhood.
How much does a bungalow attic conversion cost in Chicago?
Converting a bungalow attic into a master suite with a bathroom and closets runs $60,000–$150,000 depending on dormers, stairs, and finishes. It's the bedroom and second bathroom the original floor plan never had — and because the space is already framed, roofed, and on the foundation, it costs a fraction of what a comparable addition would.
How much does it cost to open up a bungalow floor plan?
Opening the kitchen to the dining room — the most popular bungalow upgrade — runs $40,000–$55,000 including beam installation. The wall is almost always load-bearing, so a steel beam with structural engineering ($8,000–$15,000 installed) carries the load once the wall comes out.
What hidden problems do Chicago bungalows have?
The common finds behind plaster and under floors: knob-and-tube wiring removal ($8,000–$15,000), galvanized plumbing replacement ($12,000–$20,000), asbestos or lead remediation ($10,000–$25,000), layered subfloors — sometimes four deep ($3,000–$8,000), and foundation repairs ($10,000–$40,000). Budget a 15–25% contingency on any pre-1940 bungalow.
Do I need permits to renovate a bungalow in Chicago?
Yes. Structural changes, electrical, plumbing, and HVAC work all require Chicago Department of Buildings permits — total permit costs typically run $1,500–$3,000, and standard approval takes 4–6 weeks. If you're removing a load-bearing wall, a structural engineer evaluation is required. Beverly and Morgan Park historic districts add review time. Assembly Squad handles all permitting and inspections in every fixed-price proposal.
Is renovating a Chicago bungalow worth it?
Yes — when the character stays. Period-appropriate bungalow kitchen renovations return 75–85% ROI and updated bungalow kitchens sell 25–30% faster in Chicago's market, while modern updates that strip the character return 65–75%. Our Logan Square full-gut bungalow — open main floor, attic master suite, finished basement — added $175,000+ in value on a $195,000 investment, a 90% return.
