Back in 2010, a representative from HUD (The U.S. Department of Housing and Urban Development) flew from Washington D.C. to Los Angeles to interview Modative, along with a few other key players in Los Angeles's Small lot Subdivision Ordinance. The goal was to create a report (which they did) summarizing the background, goals, guidelines, and potential improvements to the Small Lot Ordinace.

The report does a great job of outlining the important issues involved in small lot development, from parking to financing and entitlements. It's a great resource for real estate developers, architects, and municipalities looking to impliment similar ordinances. Check out HUD's report on Small Lot Subdivision here.
