Chicago Bathroom Remodeling

In Irving Park's Villa District — 126 Prairie- and Craftsman-influenced homes across seven blocks, largely built 1907–1925 — exterior work needs approval from the Commission on Chicago Landmarks before the Department of Buildings will issue a permit, so we sequence design review ahead of construction dates. Citywide, any building rated red or orange in the Chicago Historic Resources Survey carries a hold of up to 90 days on demolition permits under the 2003 Demolition-Delay Ordinance, which matters whenever a project weighs gut renovation against replacement. And under the Northwest Side Preservation Ordinance, demolition surcharges in the designated 606-area blocks of Logan Square, Avondale, Hermosa, Humboldt Park, and West Town rose in October 2024 to $20,000 per unit and $60,000 per building — economics that push owners of older multi-unit buildings toward the deep renovations we favor anyway.

The Prairie- and Craftsman-influenced homes built 1907–1925 often feature original plumbing systems with cast-iron drains and galvanized supply lines, requiring careful replacement to modern standards. For bungalows and two-flats, primary suites are often carved from small existing bedrooms or created through attic conversions, which are now more feasible with the city's ADU ordinance. Full basements, when finished into living space, provide opportunities for adding new bathrooms with proper venting and floor structure for tile. The presence of lead water service lines, as shown on the Service Line Inventory map, is a critical consideration for any bathroom remodel, impacting supply line replacement. Demolition surcharges under the Northwest Side Preservation Ordinance in areas like Logan Square and Avondale encourage deep renovations rather than full replacement, meaning existing bathroom layouts are often reconfigured rather than entirely demolished. In landmark districts like Villa District, design review for exterior changes can influence the sequencing of interior bathroom work if it impacts venting or window placement.

Plumbing permits are a critical component of nearly every bathroom remodel in Chicago, triggered by changes to drain lines, vent pipes, or water supply lines. GS Construction & Remodeling manages all required permit applications and schedules inspections for plumbing, electrical, and any structural modifications.
