Joliet, IL
Large Victorians, historic districts and a city across nine townships
Joliet has large Victorian homes, many of them cut into apartments in the 1940s, and about 52,737 housing units in total. You might own one of those and want it back to a single family home, or have a newer lot and want to start from scratch. RL Builders takes on custom homes, additions and high end remodels here.
We work out of Lemont, and Frank Lello is on site every day, so you have one person to call. We build only on land you own, from your plans or with your architect and designer. Most of our work comes through referrals, and we'll arrange references and tours.

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 Joliet
Joliet requires permits for new construction, additions, structural alterations, interior remodels and system changes. The Building and Inspectional Services Division is at 150 W. Jefferson Street. Contractors must have registration on file before a permit is issued, and electrical, plumbing and HVAC contractors each need a letter of intent for every project. Line those up before you submit.
New construction inspections include footings, foundation walls, framing, insulation and final, and the building must be complete before a certificate of occupancy. The city lists the 2015 IBC and IRC with the 2024 IECC as its energy code. It also has a Storm Detention Ordinance, No. 7039, which your plans may need to respect.
Historic review is the part many owners miss. Exterior changes to designated historic properties need a Certificate of Appropriateness from the Historic Preservation Commission, and it must be approved before you apply for a building permit. Interior modifications to those properties are not subject to Commission approval. The Joliet East Side Historic District (1980) and the Upper Bluff Historic District (1991) are on the National Register of Historic Places. Ask the city whether your address is a designated property.
The city also runs across nine townships, more than any other Illinois city. We coordinate the permits, line the plans up with the city's codes, and keep the electrical in house as a licensed electrical contractor. For an older house, look at our whole home renovations.
