Does Lansing, IL have zoning, and what does it mean for RVs, lot size and setbacks?

Yes. The Village of Lansing applies its own zoning code to all land inside village limits, and every use must be a permitted or special use in its district¹. Living in an RV is not allowed: the village code says no recreational vehicle may be used for living, sleeping or housekeeping in any zoning district². A parked RV on residential property must sit in a garage, an enclosed building, a driveway or the rear yard, at least 5 feet from the rear and side lot lines².

For a single-family detached home, minimum lot area is 8,450 sq ft in R1, 7,150 sq ft in R2 and 8,100 sq ft in R3⁷. Front setbacks are 25 feet in R1 and 20 feet in R2⁸. A house may rise 30 feet or 2½ stories, whichever is lower⁹. We could not confirm the rules for tiny homes or accessory dwellings; ask the village Planning office¹⁰.

Do you need a building permit in Lansing, and who issues it?

Building permits inside Lansing come from the village, not from Cook County. The Village of Lansing Building Department states that it issues permits and contractor licenses³. Cook County's Department of Building and Zoning handles unincorporated areas only and sends inquiries about municipalities to the local authority⁵.

The village has adopted the 2015 International Residential Code, including all appendix chapters, for residential construction⁶. We could not confirm the village's fee schedule, inspection stages or any owner-builder rules, so call the Building Department before you design or hire anyone.

Who runs the Lansing Building Department and how do you reach it?

The Village of Lansing Building Department is at 3141 Ridge Road in Lansing, and its office number is (708) 895-7193³. The department enforces the village codes that govern construction, rehabilitation and maintenance of residential and commercial buildings³.

Zoning questions, the zoning map and the planning and zoning appeals board sit with the village's Economic Development & Planning department¹⁰. Neither office is the Cook County Department of Building and Zoning, which serves only unincorporated Cook County⁵.

How do septic permits work inside Lansing?

Septic permits for Lansing come from the Cook County Department of Public Health, which reviews and approves private sewage disposal systems throughout Cook County except in four named municipalities, and Lansing is not one of them⁴¹¹. Illinois requires plan approval from the state or a local health authority before any new private sewage system is built¹².

We could not confirm whether the village requires a public sewer connection, which would make a septic system unnecessary on most lots. Ask the Building Department before you plan one. Cook County's soils are also poor for conventional drain fields, so expect a site evaluation¹³.

Can you live in an RV or tiny home in Lansing?

Not in an RV. The Village of Lansing prohibits using a recreational vehicle for living, sleeping or housekeeping in any zoning district². That includes a lot you own and a lot where you are building a house.

We could not confirm a rule for tiny homes in Lansing, so treat a tiny home as needing the same zoning approval, lot size and building code as any other dwelling and ask the Building Department first⁷⁶. A tiny house on wheels is likely to be treated as a recreational vehicle, which the village bars from living use².

Building a home in Lansing: the steps, in order

1. Confirm the lot's zoning district on the village zoning map through the Economic Development & Planning department¹⁰.
2. Check lot area and setbacks for that district, for example 8,450 sq ft minimum in R1 and a 25 foot front setback⁷⁸.
3. Ask the Building Department about sewer service; if the lot has none, get Cook County Department of Public Health approval for a septic system¹¹.
4. Apply for building permits with the Village of Lansing Building Department, designing to the 2015 International Residential Code³⁶.
5. If the lot is in the 100-year floodplain, expect floodplain protections that apply to new buildings over 70 square feet¹⁴.

What stays with Cook County, and what to check before you buy in Lansing

Outside village limits, Cook County's rules apply instead; see the Cook County page for unincorporated land. Inside Lansing, county-level septic and well review stays with the Cook County Department of Public Health⁴.

Before you buy, check floodplain status, because Lansing regulates development in the 100-year floodplain and treats an RV on site more than 180 days a year as a building¹⁴. Cook County's effective property tax rate is about 2% and its median property tax bill is $6,053 a year¹⁵¹⁶. Those figures are county-level, not Lansing-specific.

Watch-outs

• Searches for Lansing building permits often surface Cook County's Department of Building and Zoning, which serves unincorporated areas only; inside Lansing the village Building Department applies⁵³.
• We could not confirm building permit fees, inspection steps, owner-builder rules, sewer connection requirements or tiny home rules for Lansing; call the Building Department at (708) 895-7193³.
• A parked RV is limited to a garage, enclosed building, driveway or rear yard, and may not be stored in a side or front yard².
