Zoning, building permits and septic rules in Round Lake Park, Illinois

The Village of Round Lake Park, Illinois, in Lake County, requires building permits and inspections for new buildings, additions, renovations and demolitions, and the village's Building and Zoning Department also sets zoning inside village limits12. Septic systems and wells are not a village decision: the Lake County Health Department reviews and permits them3. Land outside the village follows Lake County's rules instead.

Does Round Lake Park have zoning, and what does it mean for RVs, tiny homes and lot size?

Yes. The Village of Round Lake Park regulates land use through its own zoning chapter and an official zoning map that shows how each property is zoned25. Land uses that a district does not list as permitted or as special uses are not allowed unless the zoning chapter is amended, and special uses need public hearings, planning and zoning commission review and village board approval2.

The village's page names an R1 single-family district and a C1 local shopping district as examples5. The zoning map can be downloaded free, and a printed copy of the zoning chapter and map costs $305.

We could not confirm the village's rules on RV occupancy, tiny homes, manufactured homes, accessory dwellings, minimum home size, lot size or setbacks. Because an unlisted use is not allowed, ask the10 before you plan any of these.

Do you need a building permit in Round Lake Park, and who issues it?

Yes, for most construction. New buildings, additions to existing structures, renovations, demolitions and temporary buildings usually require building permits and inspections in Round Lake Park1. Pools, decks, fences and some electrical, plumbing and HVAC work may also need permits, and the village charges a permit fee1.

The Village of Round Lake Park Building and Zoning Department issues building permits and accepts applications by fax, in person or by email410. An application asks who will perform the work, what the work is and how it will be done4. We could not confirm whether owner-builders are exempt or what the fee schedule is, so ask the department.

What codes and inspections apply in Round Lake Park?

The village's page lists the 2018 IBC, 2018 IRC, 2018 IFC, 2011 NEC and the Illinois Plumbing Code as adopted codes7. The village inspects each major phase of construction, and whoever does the work must schedule inspections at least 24 hours in advance610.

Round Lake Park also requires an occupancy inspection every time there is a change in residence, for rentals and owner-occupied homes alike, and the occupancy inspection fee is $7511. Schedule it at least 24 hours ahead11.

How do septic permits and well permits work inside Round Lake Park?

The Lake County Health Department, not the village, handles septic and well review for Round Lake Park properties. Property alteration and addition projects on properties with a septic system or well must be reviewed and approved by the Lake County Health Department3. An onsite wastewater treatment system on an unsewered property needs a construction permit, with plan and soil evaluation forms8, and wells need a construction permit as well9.

The department regulates sewage treatment and dispersal for septic systems on properties not served by a public sewer system12. Whether a given lot is on public sewer is a question for the village and the health department. We could not confirm village-specific septic inspection rules.

Building a home in Round Lake Park: the steps, in order

  1. Look up the lot's zoning on the village zoning map and confirm your use is permitted or a special use52.
  2. Call the10 to ask about setbacks, lot size and any RV, tiny-home or accessory-dwelling plans, which we could not confirm.
  3. If the lot has a septic system or well, or needs one, get Lake County Health Department review and permits first3.
  4. Apply for a building permit with the village4.
  5. Schedule village inspections at least 24 hours ahead as each major phase is built6.
  6. Schedule the occupancy inspection before anyone moves in11.

What stays with Lake County, and what to check before you buy in Round Lake Park

Septic and well permits stay with the Lake County Health Department, as described above3. For land outside village limits, see the Lake County page rather than the village's rules.

County figures give context: Lake County's effective property tax rate is 2.7%13, and the median property tax bill is $8,743 a year14. We could not confirm floodplain, driveway or short-term rental rules inside the village; ask the Building and Zoning Department.

Watch-outs

  • A use that the village zoning chapter does not list as permitted or as a special use is not allowed without a zoning amendment, so confirm RV, tiny-home and accessory-dwelling plans with the Building and Zoning Department before you buy2.
  • A change in residence triggers an occupancy inspection with a $75 fee, including when you buy an existing home11.
  • Septic and well work needs Lake County Health Department approval even though the village issues the building permit3.
