Room Addition FAQs
How much does a room addition cost in Chicago?
A standard room addition in Chicago runs $70,000–$150,000 depending on size, foundation work, and finish level. Simple bump-outs on existing foundations cost less than additions requiring new footings.
Do I need a permit for a room addition in Chicago?
Yes, any addition that increases your home’s square footage requires a Chicago building permit and zoning review, which we handle for you from start to finish.
Should I build up or build out for a room addition?
It depends on your lot size and remaining buildable footprint. If your lot is near its FAR limit, building up (adding a second story) may be your only option; if you have yard space, building out is usually less expensive.
How long does a room addition take to complete?
Most room additions take 8–14 weeks to build once permits are approved, with 4–8 weeks of design and permitting time beforehand.
Will a room addition require a zoning variance in Chicago?
If your addition exceeds your lot’s allowable floor area ratio or encroaches on required setbacks, you may need a variance. We evaluate this during the design phase before you commit.
Can I add a room addition to a Chicago two-flat or bungalow?
Yes — we regularly add rooms to bungalows, two-flats, and greystones, matching the addition’s brick, trim, and roofline to the original structure.
Will a room addition affect my property taxes?
Added square footage typically raises your assessed value at your next Cook County reassessment cycle, proportional to the value the addition adds to your home.
