Building in Long Grove — What We Know About This Community

Long Grove is unique in the Chicago suburbs a village that has deliberately preserved an unincorporated, low-density rural-suburban character defined by mature trees, generous lots, and an architectural diversity that ranges from substantial farmhouses to thoughtful contemporary homes. Building in Long Grove means working with septic and well infrastructure, navigating large-lot zoning, and respecting a community that has consciously chosen a different path than its more densely developed neighbors. Forest Heart Builders has built extensively in Long Grove and we know its rhythms.

Site Considerations Unique to Long Grove

Long Grove relies on private wells and septic systems. Soil characteristics vary across the village, and proper geotechnical and percolation evaluation is essential during Discovery. Many properties include wooded areas, drainage swales, or low-lying sections that require thoughtful site planning. Building setbacks, lot coverage limits, and conservation requirements vary by zoning district. We coordinate with the village's planning office during Discovery so that design proceeds with full clarity on what is allowable.

Projects We Build in Long Grove

Ground-up custom homes on large wooded lots from refined farmhouses to thoughtfully contemporary residences; whole-home renovations of established Long Grove estates; additions including primary suite expansions, great-room reworks, and outdoor pavilion construction; and architectural millwork for clients whose homes are largely complete but want a defining library or built-in installation.

Working With Long Grove's Building Department

The Long Grove building department is professional and consistent, and we have submitted multiple projects through their permitting process. We know the documentation that smooths approval, the inspection schedule the village follows, and the protocols that keep an active build moving cleanly through the permitting and inspection cycle.

What Makes Long Grove Different

Long Grove's zoning preserves a minimum lot size that gives the community its distinct character  far fewer homes per acre than surrounding suburbs, mature tree canopies preserved by intention, and an architectural tradition that emphasizes rooted, substantial residences. The village's historic downtown  a preserved 19th-century commercial district  anchors the community's identity. Custom homes here read against that backdrop, and the most successful Long Grove homes feel rooted in the land rather than dropped onto it.
Common Questions

Frequently Asked Questions

Does Long Grove's unincorporated character affect the building process?
It does, in helpful and less-helpful ways. The village has its own building department, inspection schedule, and zoning provisions. Most projects also involve Lake County environmental health for septic and well permitting. We coordinate all the relevant jurisdictions during Discovery and Design so the construction phase proceeds without permitting friction.
Can you build a modern contemporary home in Long Grove?
Yes — and several of our most thoughtful contemporary homes have been built in and around Long Grove. The architectural language that succeeds here grounds modern design in natural materials and proportions that respect the setting. Done well, contemporary architecture reads beautifully in Long Grove's wooded landscape.
What is well and septic planning like in Long Grove?
Most Long Grove projects involve a private well and a private septic system. Well placement, septic field sizing, and the relationship between the two are governed by Lake County health regulations and the specific soil conditions of your site. We engage licensed well and septic professionals during Discovery to evaluate your specific property.
How does Long Grove compare to nearby Hawthorn Woods or Kildeer for custom home construction?
All three share the rural-suburban character and large-lot zoning that define this corner of Lake County. Long Grove tends toward broader architectural diversity. Hawthorn Woods includes more lake-adjacent properties on Indian Lake and surrounding waters. Kildeer retains stronger equestrian heritage. We have built in all three and the differences are real but subtle.
