Public hearings will be held this spring on a city development plan called the Housing Element, which assesses the need and charts city policies designed to meet it.
The new unit construction "is doable, but not easily doable," principal planner Jane Blumenfield of the City of Los Angeles told the Daily News.
The construction goal comes as residents in some suburban areas are voicing unhappiness with L.A. policies aimed at concentrating dense development along transit lines and arterial streets.
And the study's release also came at a time that housing advocates at UCLA said the city has fallen behind in meeting the need for low-income housing, with just one fifth of the needed units built between 1998-2005.
And in the same period, 9,000 rental units were converted to condominiums, making it more difficult for renters to find affordable housing, housing advocates said.
