Property Alteration and Addition Permits 

Property alteration and/or addition projects on properties with a septic system or well must be reviewed and approved by the Lake County Health Department. Construction must meet horizontal separation distances from the septic tank, septic field (primary and reserve areas) and water well. See Appendix D for a table of separation distances.

Projects include, but are not limited to:

  • Small house additions (less than 50% square footage addition, no change in the number of bedrooms)
  • Basement remodeling or additions
  • Decks and patios
  • Retaining walls
  • Sidewalks
  • Sheds
  • Garages (attached or detached)
  • Driveways
  • Sports courts
  • Gazebos
  • Swimming pools
  • Fences
  • Site grading or filling
  • Installing drainage and water conveyance pipes

Applying for a Permit

Plans may be reviewed at the time of submission (counter review). Plans may also require file and records research (submittal based).

The Health Department may review your request with other county departments as needed. The Health Department requires the following documents be submitted for review:

  • Three copies of a plat of survey or site plan drawn to scale. This must show the proposed project construction and all existing buildings, driveways, parking areas, well, and components of the septic system (tanks and seepage field). A plan of the septic system layout on file with the Health Department may be used. If a drawing is not available or unclear, then one must be made by a licensed Lake County septic system contractor.
  • If the project is an addition or change to a floor plan to an existing structure three copies of the existing and proposed floor plans are needed. Closets must be included. Floor plans must be drawn to scale. Rooms of the floor plans must be labeled. Architectural plans may be needed. An increase in the number of bedrooms (by code definition) and/or a greater than 50% increase in square footage requires that the septic system meets current code.
  • Completed Property Alteration/Addition application from the Health Department.
  • Payment per the Lake County Health Department Environmental Health Fees Schedule and other applicable County Department fees.

If you live in unincorporated Lake County, please visit the Lake County Planning, Building, and Development website for other permits and approvals you may need. 

If you live in a municipality, please visit their website for their requirements. 

Well Water Permit Assistance

The Water Well Program issues permits for construction of all new private, semi-private and non-community water wells, and inspects each after its completion to assure it is constructed properly. We also assure that a satisfactory water sample result is obtained from each newly constructed well prior to issuing final approval. Over the past 10 years, there has been an average of 435 permits issued for new water wells each year. The Water Well Program also issues permits for the sealing of any abandoned wells, many of which are sealed when a replacement well is constructed for an existing home.

Proposed Projects

Some proposed projects, such as tear down/re-builds on sites with an existing water well very likely will require the involvement of several Lake County agencies during the review process. To streamline the submittal process, a Lake County Project Manager will be assigned to your project to guide you through the process. The Project Manager will serve as a single point of contact to answer any questions, coordinate the project approval process, resolve issues that affect the project flow, and keep project approval on established time lines.

Requesting Early Assistance

Prior to submitting your project, you may request an early assistance meeting by contacting a Project Manager at 847.377.2600. Early assistance meetings are provided at no charge and the meeting will be coordinated by a Project Manager to ensure all involved Lake County departments are present to address your proposed project. The meeting will identify project requirements and design issues before the project begins. The meeting may offer guidance on the best use of a complicated site. Minutes from the meeting will be provided for your use in design, layout and/or calculations that may be required for your proposal.

Inspections & Samples

Health Department staff routinely inspect and sample the county's  412 non-community wells which serve the public at facilities such as schools, restaurants and businesses. Of these 412 non-community wells, about 67 serve the same 25 or more people six months or more each year. These facilities are required to submit samples for chemical analysis as well.
