Oak Brook, IL
A village of subdivisions, and what that means for your lot
RL Builders builds custom homes and high end remodels for owners in Oak Brook. The village is mostly residential subdivisions, with the retail and office property gathered along 22nd Street and the I-88 corridor, and RL builds only on land the owner already holds.
Frank Lello is on site every day of the job, and you deal with one person the whole way. References and tours of finished RL homes are available on request.

Homeowners on working with Frank
Frank and his team built our dream home through COVID, and the quality has been exceptional. Years later he still checks in seasonally and stays a call or text away, which is rare and appreciated.
Julie Morris, homeownerFrank handled our kitchen renovation and we could not be happier with the final project. He was on site every day, used skilled craftsmen, and made what could have been stressful feel easy.

What to know before building in Oak Brook
Oak Brook's Development Services Department (Building Division) takes residential permits through an online portal. Every required document has to be uploaded when you submit, or the application can't be filed at all. A missing plat of survey stops the whole thing, so the package has to be complete on day one.
New homes, some additions, land modification, driveways, retaining walls within easements and work in the village right-of-way all need the village's engineering permit. An addition application asks for architectural plans, engineering plans, a plat of survey, approval from the Flagg Creek Water Reclamation District, energy compliance documents and a covenant running with the land. If your subdivision has a homeowners association, its approval goes in the package too.
Teardowns have their own steps. The demolition application needs a plat of survey, Flagg Creek approval, association approval where it applies and a neighbor notification. The notice is mailed to residents within 250 feet, and the permit is issued no sooner than ten days after the certified mailing date. Once it's issued, the code calls for a six-foot chain link fence around the work and silt fencing for erosion control.
Under section 10-1-6 of the village code, the site also needs a covered dumpster set back at least ten feet from any side lot line, and a construction traffic management submittal has to be in before a demolition or new principal structure permit is issued. The planning and zoning page lists a Certificate of Appropriateness application next to variations, special uses and appeals, so ask the village early which of those your lot might need. RL coordinates the permits and lines the plans up with the village's rules. See custom homes.
