Do You Actually Need a Permit?

It's the question we get on almost every first call: do we really need a permit for this? In Chicago, the honest answer is — for more than you'd think, yes. And the city's enforcement isn't theoretical: unpermitted work surfaces at the worst times, usually when you sell, refinance, or file an insurance claim.

Work That Requires a Permit

• Moving, removing, or adding walls — load-bearing or not
• Any new or relocated plumbing, electrical, or HVAC
• Basement finishing and attic conversions (these create habitable space)
• Additions, garages, decks, and porches
• Most structural repairs — joists, beams, masonry, foundations

Work That Usually Doesn't

Painting, flooring, cabinet replacement in the same layout, countertops, trim, and like-for-like fixture swaps generally don't require a permit. The pattern: cosmetic surface work is fine; anything touching systems or structure is not.

Chicago's Two Tracks

The city runs an Easy Permit Program for simpler repair-and-replace work — no architectural drawings, often issued same-day, typical costs in the low hundreds. Larger scopes go through the Standard Plan Review: stamped architectural drawings, plan examiner review, and a timeline measured in weeks, not days. A kitchen that keeps its layout might ride the easy track; a gut rehab never does.

What Unpermitted Work Actually Costs

The fine is the small part. The real costs: buyers' attorneys flag it during sale and demand escrow holdbacks or price cuts; insurers can deny claims tied to unpermitted systems; and the city can require you to open finished walls for inspection — paying twice for the same work. The permit fee is the cheapest insurance in construction.

The Bottom Line

If your project touches walls, water, wires, or gas — assume a permit. Build the timeline into your plan (we do this on every estimate), and treat any contractor who waves the requirement away as telling you something important about how they run the rest of the job.
