Accessory dwelling units (ADUs) are becoming more popular, but there is little guidance available for creating them or getting projects approved. That's why Michael Litchfield, a founding editor of Fine Homebuilding
magazine, wrote In-Laws, Outlaws, and Granny Flats
(The Taunton Press, $24.95, March 2011). The book explores the various uses and designs for ADUs, from attic apartments to garage conversions and backyard cottages, and addresses every aspect of adding a residence to a single-family home. In addition to chapters dedicated to assessing your ADU needs, selecting a design, and getting plans approved, Litchfield also offers a portfolio of case studies complete with color photos, floor plans, and architectural details.
