E-Plans.com, StantonHomes.com and HomePlans.com are three online resources with in-law suite floor plans. These plans are available for free viewing, and some also permit free printing. Some plans also come with customization options, and E-Plans and Home Plans also offer PDF and other format copies of their plans for sale.
In-law suites plans on E-Plans each come with bedrooms, and some also have kitchenettes and small living areas. The suites are separate from their host houses either by design, such as existing in basements or above attached garages, or by separation via a breezeway or other structure.
Entries on all three websites include dimensions and number of rooms
