Building an accessory dwelling unit (ADU for short) can be a great way to add a home office, provide housing for parents and boomerang kids or generate income as a rental property.
But large home improvement projects are notoriously a time-consuming hassle. Seemingly endless meetings with architects and contractors leading to projects that are over budget and behind schedule. That’s where Chicago Granny Flats comes in.
Founded by two developers and an architect, Chicago Granny Flats, LLC, specializes in building upscale, high-quality and cost-effective detached ADU’s in a fast, efficient and user-friendly format.
“We’re striving to make the whole process completely plug and play” explains CEO David Schwartz; “We provide the plans, pull the permits, complete the construction and offer access to financing – a true one stop shop.”
Often called “Granny Flats” for their historical link to multigenerational housing, ADU’s are a way for communities to add housing without negatively effecting the feel and look of a neighborhood.

Zoning ordinances allowing ADU’s have been picking up steam nationwide and the City of Evanston recently enacted a sweeping ordinance among the most progressive in the country. An ADU can be added to just about any single family, multifamily or commercial property in the city.
Although ADU’s can include units added to unused attic or basement space, Chicago Granny Flats only builds coach houses.
This allows for a system-built approach featuring light gauge steel wall panels that produce an environmentally friendly, energy efficient building in a fraction of the time with less noise and less mess than traditional construction methods. From receipt of building permit to handing over the keys can take as little as four weeks.
Each model offered by Chicago Granny Flats features a 2, 3 or 4 car garage and up to a two-bedroom apartment on the 2nd floor.
Choices of exterior styles allow clients to complement the architectural style of the primary building on the property and curated interior design themes, including an empty shell for those DIY-ers, allows customers to personalize their coach houses.
