How long does a Chicago building permit take to issue?

A realistic timeline for general contractors and owners working in Chicago · Updated June 2026

For a contractor, the timeline is not trivia. The weeks a permit spends in review are your window to research the owner while the team may still be forming.

If you're a contractor watching for the right moment to bid, or an owner trying to schedule a project, knowing the realistic Chicago timeline matters more than knowing the average. Chicago is unique among major U.S. metros because the city offers four parallel review tracks, and the track choice is often the single biggest determinant of how long your permit takes.

How long does each Chicago permit type take?

PermitPipeline tracks every new filing in Chicago's Department of Buildings system. From the Chicago Data Portal building permits dataset (ydr8-5enu), the typical durations look like this:

These are observed medians from the past year of filings. The mean is much higher because of long-tail outliers — projects that stall in PD entitlements, zoning challenges, or community appeals. If you're underwriting a schedule, plan from the median and budget contingency for the long tail. South and West Side projects without Planned Development triggers move fastest. North Side, downtown, and lakefront projects need the most contingency.

What's actually happening between filing and issuance on a Chicago permit?

The clock has four stages. Easy Permits and Self-Cert skip most of stage 2. Standard Plan Review and Developer Services projects go through all four.

1. Initial intake (1–3 business days). The filing is logged at the Department of Buildings, routed to the chosen review track, and assigned to a plan examiner queue. Easy Permits get issued at intake. Self-Cert permits are issued unless flagged for audit.
2. Plan review (3–12 weeks for Standard). Plan examiners check structural, mechanical, electrical, plumbing, fire, accessibility, and zoning compliance. They issue corrections in writing. First submissions rarely pass clean. Each round of corrections adds 1–3 weeks. See our companion piece on Chicago's four permit review tracks.
3. Special review when triggered (4 weeks to 18 months). Landmarks Commission for designated buildings or districts. Zoning Board of Appeals for variances. Plan Commission for Planned Developments. Department of Housing for projects subject to the Affordable Requirements Ordinance. Each adds its own queue.
4. Permit issuance (3–10 business days after final approval). Once corrections clear, fees are paid, and required department sign-offs are in, the permit issues.

Why does Chicago plan review vary so much in duration?

Plan review is the second-biggest source of variance after track choice. The first variable people miss: Chicago plan review staffing levels swing dramatically with the city budget cycle, and the queue depth in March is often half of what it is in November.

What slows Chicago plan review:

• Open Violations on the property. The Department of Buildings will not issue a new permit while unrelated violations are open. Common on older South and West Side properties. Clearing violations can take weeks on its own.
• Zoning Board of Appeals variance needed. If the project requires a variance, the ZBA hearing schedule sets the floor. Hearings are monthly. Miss one, wait the next.
• Landmarks Commission referral. Anything in a designated district or on an individually landmarked building goes through Landmarks first. Adds 4–12 weeks before the building-code review.
• Affordable Requirements Ordinance (ARO). Residential projects of 10+ units route through the Department of Housing's affordable-unit calculation. Adds Housing review even if everything else is clean.
• Planned Development zoning. Downtown, lakefront, and large North Side projects often sit in PD zoning. PD changes require City Council action — a months-long political process.
• Alderman hold at the ward level. Aldermen have effective veto power over zoning changes in their wards. A skeptical alderman can pause a project for as long as they want.

What's already happening on a project before the Chicago permit issues?

This is the part most contractors miss: by the time the filing is in the public record, the owner has been planning for months. The architect is engaged. The structural and MEP engineers are usually drawing. The general contractor may already be in conversations. The MEP subs are often pre-selected, especially in Chicago where established relationships dominate downtown and the North Side.

The implication: the public filing is your one of the last public signals before the team is likely more fixed. Wait until permit issuance and the bid list has usually closed. Reach out at filing and you may be earlier than after issuance, especially on jobs where the owner doesn't have a long-standing Chicago GC relationship. In Chicago specifically, projects in the South and West Side wards, smaller developers, and out-of-state owners are the highest-yield outreach targets because they're less locked into local networks.

How can Chicago timing data help contractors bid smarter?

Once you know the typical wait by track and trigger, you can be strategic about which filings to chase first. Three quick rules:

• Standard Plan Review filings are your sweet spot. Long enough wait (6–16 weeks) that you have time to research the owner. Real enough that the project is committed and likely to break ground.
• New construction filings need patience. A new Chicago construction filing might be 9–12 months from groundbreaking. Build the relationship now, but don't expect a quick close. Earlier is better — see why.
• Skip pure Easy Permits. The wait is short, the scope is small, and by the time you research the owner the work is usually done. The exception: Easy Permits on commercial spaces that signal a tenant move-in.

What practical Chicago permit timeline can a contractor use?

Here's how a realistic Chicago Standard Plan Review job actually unfolds, with the dates you can research the owner at each step:

1. Day 0: Owner files job application. Filing appears in the Chicago Data Portal within 1–2 business days.
2. Days 0–21: Plan review queue. Owner is finalizing scope, often still picking GC.
3. Days 21–60: First round of corrections. Architect responds. This is the warmest window for outreach.
4. Days 60–105: Correction response and re-review. Special review (Landmarks, ZBA) often runs in parallel here. GC is often being chosen around now, sometimes already selected.
5. Day 105–120: Permit issued. Work can begin. Bid list often closed or narrowing.

If you reach out in the days 21–60 window with a credible specific message, you may face less competition than after issuance. By day 105, you're competing in a more crowded field.

Why are most Chicago contractors too late on the best work?

Most GCs check the Chicago Data Portal after permits issue. That's the data that's easy to find and easy to filter. By then the bid list is set. The contractors who consistently win mid-market Chicago work are the ones who've built a habit around the filing-to-issuance window. They're not waiting for the project to be advertised. They're treating the filing itself as the lead.

That's the workflow PermitPipeline is built around. Chicago DOB filings are scored, deduped, and emailed out the morning after they hit the public record, so your first chance to research the owner doesn't disappear into a 100-row CSV. See what today's Chicago filings look like in our feed.
