Do you need a building permit in Village of Tinley Park, IL?

Tinley Park requires building, electrical and plumbing permits for most home improvements or additions, allowing review for safety, zoning compliance and sound construction.2 A homeowner doing the work must still obtain the building permit before starting.1 Driveways are among the residential projects for which residents should apply or check with the Building Division.6 Tinley Park lists adopted building codes, including the International Residential Code, and provides an inspection sheet tailored to each permitted project.75

Who handles building permits in Village of Tinley Park?

Contact the Tinley Park Building Division at (708) 444-5100 or [email protected] for building-permit questions.2 For a homeowner application, the village asks for a plat of survey and pertinent drawings, blueprints or sketches; the proposed improvement and dimensions must be located on the survey.2 The applicant also completes a building-permit application.2 Once the building permit is issued, the village supplies a placard to display at the site until completion and a sheet identifying the required inspections.2

Does Village of Tinley Park have zoning and setback rules?

Tinley Park publishes a zoning-district map, district regulations, schedules of regulations, supplementary regulations and overlay regulations.3 The village Planning and Zoning Division handles land development and works through the review process for variations, special uses and rezoning.8 Before choosing a house footprint, ask that division to identify the parcel’s district and applicable schedule.38 We could not confirm the numeric residential minimum lot size, minimum dwelling size, setbacks, lot coverage or height limits; request the parcel-specific limits from Tinley Park Planning and Zoning.8

How do septic permits work inside Village of Tinley Park?

In the Cook County portion of Tinley Park, CCDPH provides regulatory oversight, plan reviews and inspections for private septic systems.4 CCDPH reviews and approves private sewage disposal systems throughout Cook County except the incorporated municipalities named on its septic page.9 For a system review, CCDPH lists a completed application, scaled system plans, a soil report and other applicable documents.9 Ask Environmental Health about the proposed system before finalizing the house layout, and request an evaluation when buying a property with an existing well or septic system.9

Can you live in an RV or tiny home in Village of Tinley Park?

We could not confirm whether Tinley Park allows private-land RV occupancy, temporary camping, tiny-home occupancy, manufactured homes or accessory dwellings; ask village Planning and Zoning about the specific dwelling and proposed use.8 Tinley Park’s published zoning districts and schedules are the starting point for that parcel review.3 We also could not confirm an off-grid sanitation allowance or a mandatory sewer-connection threshold; ask the Building Division what sanitation arrangement can be approved for the address before relying on an off-grid plan.2

What are the steps for building a home in Village of Tinley Park?

First, take the parcel and proposed residential use to Tinley Park Planning and Zoning to identify the district regulations and any land-use approval needed.38 Next, ask the Building Division for the building-permit submission requirements and prepare the survey and project drawings.2 If the Cook County parcel uses private septic, contact CCDPH for system review and inspection requirements.4 Obtain the building permit before work starts, display the permit placard, and follow the project’s inspection sheet during construction.12

What should you check before buying in Village of Tinley Park?

For a Tinley Park parcel, resolve the intended use and zoning district with village Planning and Zoning before committing to the building design.38 For a Cook County property with a well or septic system, CCDPH says an evaluation is typically needed when buying or selling.9 We could not confirm the village’s operative floodplain-development requirements; ask the Building Division which floodplain review applies to the parcel.2 For land outside village limits, consult the Cook County guide: the county’s building-permit requirement concerns unincorporated Cook County.10

Watch-outs

  • Tinley Park’s homeowner allowance does not waive the building permit, and electric-service changes require a licensed electrical contractor.1
  • The $50 Change of Use/Owner application fee concerns that specific process; it is not a quoted fee for constructing a home.11
  • CCDPH septic oversight described here applies to the Cook County portion of Tinley Park; confirm the parcel’s county before arranging private septic review.4
