Pilsen zoning — Chicago
7,105 lots, and 45% of them carry one district. Here is what the zoning on the ground looks like — and what outranks it.
Counted from the parcel table the LotGrade analyzer reads, by the City of Chicago’s neighborhood boundary — not the community area, which draws a different and wider line. The city publishes no Pilsen polygon; the boundary counted here is the one it calls Lower West Side, which covers the same ground. Zoning rules link to Title 17 in our hosted zoning code.
On the ground
What Pilsen is zoned
No district dominates: the largest, RT-4, covers 45% of the lots here. That is the number worth knowing first, because it sets what a typical lot here can become before any overlay or relief is considered.
| District | Lots | Share |
|---|---|---|
| RT-4 | 3,162 | 45% |
| RS-3 | 790 | 11% |
| B3-2 | 758 | 11% |
| C1-2 | 746 | 10% |
| PMD 11 | 414 | 6% |
| M1-2 | 221 | 3% |
| M2-3 | 160 | 2% |
| B2-3 | 148 | 2% |
| 54 other districts | 706 | 10% |
The 8 most common of 62 zoning districts among 7,105 lots, counted from the same parcel table the analyzer reads. Planned developments and planned manufacturing districts appear under the number stamped on the map, as PD 30 or PMD 9; each is negotiated on its own terms, so there is no district page behind the number.
The typical lot
What a normal lot here looks like
The median lot in Pilsen is 3,000 sq ft; the average is 11,268 sq ft, pulled up by the larger parcels above it. A standard Chicago lot is 25 × 125 ft, or 3,125 sq ft, so the middle of this neighborhood is the standard lot almost exactly.
To see what that allows — setbacks, floor area, height, units, open space and parking, each cited — put the district and the lot size into the Chicago zoning calculator. For the reasoning behind each number, start with floor area ratio and how many units fit.
Overrides
Three rules outrank the district
The district on the map is where the answer starts, not where it ends. In Pilsen, three things move it:
- The 606 overlay — 4,051 lots, 57% of them. Inside it, what your neighbors built decides what you may build: on a block face that is mostly multi-unit, a detached house may not be established at all. See the 606 and Pilsen block rules.
- Transit-served locations — 4,503 lots, 63%. Near rail or a listed bus corridor the parking minimum can fall to zero, and density, floor area and height bonuses come into reach. See transit-served development and parking minimums.
- Landmark status — 11 lots. A landmark or a contributing building in a landmark district needs no additional parking to rehabilitate, and demolition is a different conversation entirely.
140 lots are assessed as vacant land. A vacant lot is where the district, the overlay and the block test all apply at once with nothing existing to argue from — and where nonconforming rights give you nothing, because there is nothing to have continued.
Change
How often the map actually moves
89 zoning map amendments have been recorded in the wider Lower West Side community area between 2019 and 2026 — the City Clerk records a rezoning by community area rather than by neighborhood, so this count covers more ground than the figures above.
A rezoning is the route when the district itself is the obstacle, and it is also what pulls in the Affordable Requirements Ordinance. For the alternatives that do not need one, see variations, special uses and planned developments.
Questions
Common questions
What zoning district is most of Pilsen?
RT-4 — 3,162 of 7,105 lots, 45% of its lots. The rest runs to business and commercial districts along the corridors, with a little manufacturing. Every district is explained in the Chicago Zoning Field Guide.
How big is a typical lot in Pilsen?
The median is 3,000 sq ft against a standard Chicago lot of 25 × 125 ft (3,125 sq ft) — the standard lot almost exactly. The average is 11,268 sq ft.
Is Pilsen in the 606 zoning district?
4,051 of its lots are — 57% of them. Inside that boundary the Predominance of the Block rules apply: in RS-3 and RT-3.5, a detached house may not be established where most of the block face already holds buildings with more than one unit, and a demolition permit carries a surcharge of $20,000 per unit.
Can I build without parking in Pilsen?
On 4,503 of its lots — 63% — the site is transit-served, and outside downtown that allows the minimum to be reduced by up to 100% (§17-10-0102-B). Elsewhere in the neighborhood the district ratio applies in full.
Where do these numbers come from?
The Cook County and City of Chicago parcel records the LotGrade analyzer reads, counted by the City of Chicago's neighborhood boundary. Zoning rules come from the adopted ordinance, Title 17. Neighborhood lines are a convention rather than a legal boundary — the community area is the official geography — so treat a lot near the edge as belonging to whichever you can verify.

LotGrade reads every one of these rules against a single address in Pilsen — the district, the overlays, the block test and the buildable envelope — and shows whether the numbers work.
