How can conservancy easements affect a Long Grove purchase?

Review the recorded subdivision plat and ask the Village about conservancy and scenic corridor areas before planning a pool, clearing or an addition. Long Grove explains that many subdivisions contain conservancy easements, with restrictions that can differ between upland and lowland districts and the recorded plat. Certain encroachments or alterations involve the Conservancy and Scenic Corridor Committee and Village Board. An apparently usable yard is therefore not proof that all of it can be disturbed. Confirm the designation and proposed activity for the exact parcel before relying on an improvement plan.

Which current process should I use for a Long Grove permit?

Long Grove’s Building Department says permit applications and supporting documents must be submitted electronically through CommunityCore, by an owner or contractor. Start with that current department page and its project checklists rather than an older downloaded form. For a purchase involving renovation, describe the address and scope and ask which inspections or additional reviews apply. Keep the approved plans and permit conditions; using the portal does not by itself authorize work or resolve conservancy restrictions.

Who should review a Long Grove project near a private well or septic system?

Long Grove directs private well and septic permits, and property alterations involving those systems, to Lake County Health. It separately identifies Lake County Public Works for county water and sanitary-sewer connections or alterations. Establish the actual service type and proposed excavation before designing an addition; a Long Grove address alone does not identify the connection or responsible authority.

Does Long Grove’s absence of a municipal property tax mean a home has no property-tax bill?

Long Grove says it does not impose a municipal property tax, but its tax page illustrates payments to school, fire, county and other taxing bodies. Obtain the actual Lake County parcel bill and year before budgeting a purchase. The Village’s example expressly uses approximate 2018 distributions and cannot determine today’s charges for a specific home.

Which Long Grove tree-removal application route applies to an improvement project?

Long Grove directs applicants to its long form when removing protected-species trees or when tree removal accompanies projects such as a new home, addition, pool, patio or driveway. Bring the tree inventory and project plan to Building before choosing a removal route. A construction proposal does not itself approve removal of the affected trees.

Can a Long Grove zoning-map color establish my expansion rights?

Long Grove explains that an underlying zoning district can be modified by a property’s Planned Unit Development ordinance. Obtain the parcel’s PUD ordinance and applicable district provisions before estimating setbacks, building size or an additional use. A zoning-map classification alone does not establish permission for the particular improvement or replace formal project review.

Can I enlarge a Long Grove driveway without checking lot coverage?

Long Grove counts multiple constructed surfaces toward impervious coverage, including driveways, patios and decks. Its FAQ cautions that exceptions and stricter PUD provisions can affect the general limit and that a professional survey may be needed. Calculate existing coverage and obtain parcel-specific zoning review before treating a driveway enlargement as available space.

Does a Long Grove service-area map establish a connection?

Long Grove directs infrastructure research to Lake County’s Public Works Service Areas map. Identify the potential provider there, then confirm the home’s actual connection and account. Map coverage does not establish connection, resolve private well or septic responsibilities, or settle connection charges.

Local research · Seller questions

Who receives a Long Grove permit security-deposit refund after a sale?

Long Grove’s permit-holder guidance ties a security-deposit refund to satisfactory approval of all permit requirements and sends it to the original remitter, less unpaid permit fees. Sellers should obtain the permit closeout status and identify the remitter before allocating a refund at closing. The guidance does not automatically transfer that payment to a buyer.

Can a buyer continue a Long Grove project with a new contractor?

Long Grove compares contractors at inspections with those listed on the permit card and describes updating the record when contractors change. Ask Building to reconcile the issued plans, conditions, contractor licenses and permit status before work resumes. A purchased property and an existing permit card do not establish approval for a replacement contractor’s work.

What inspection matters when buying Long Grove space for a new business?

Long Grove’s new-business pre-occupancy process calls for building, electrical, mechanical and plumbing inspections and advance scheduling after payment. Before committing to a business-use closing date, confirm zoning separately and request the inspection requirements for the proposed occupancy. An existing shop’s prior operation does not establish approval for a new business or altered space.

Who reviews drainage concerns for a Long Grove lot or association?

Long Grove identifies its contracted Village Engineer as the Lake County Watershed Development Ordinance enforcement officer for local stormwater review and a contact for resident and association drainage inquiries. Submit the parcel, proposed grading and available plans there before designing work. An association’s agreement does not substitute for the applicable engineering and stormwater review.
