Several years later, this home still has not been brought up to code. The owner has left the home abandoned, a magnet for squatters and dumping. Representatives from the city claim there is a compliance plan in place. I’ve made countless attempts to investigate the plan for this property with no insight into next steps.

With the housing crisis in this city, we need this lot to either be freed up and sold or brought up to legal code standards.

Position starts April 9. Might be worth it to contact him.

City creates new policy director role
By David Debolt
ddebolt@bayareanewsgroup.com
OAKLAND » Mayor Libby Schaaf has named Darin Ranelletti as the city’s first policy director for housing security, a position the mayor created and hopes will help ease Oakland’s affordable housing crisis.
Ranelletti is no stranger around City Hall: He has spent the past 15 years in the planning and building department, most recently as the interim director. In his new policy role, Ranelletti is expected to promote new housing available to all income levels and work to protect longtime residents from being pushed out of Oakland’s market.
“This new position gives the Mayor’s Office the resources needed to address the housing crisis effectively and with urgency,” Schaaf said in a statement Thursday. “Darin’s 360-degree perspective begins with his work in the City’s Planning & Building Department to increase Oakland’s housing production at a record pace this year, as well as his recent efforts to protect tenants and safeguard our city’s affordable housing stock. He also has a deep passion and commitment to equity.”
Ranelletti’s first day in the new position April 9.
“I am excited to join Mayor Schaaf at this critical moment in Oakland’s history,” Ranelletti said in a statement. “There is important work we can do right now to ensure that current and future city residents have access to secure housing, which is a vital component to protecting the city’s rich cultural diversity and promoting economic prosperity for all residents.”

Unfortunately, that position doesn't really look to be addressing the dumping issue that this report was based on.
Put a person in a position to create solutions for the trash, and hold renters/ landlords, owners accountable for allowing their residence to end up like this.

This right here should be reasons for taking the property and the city reusing it as already built 'affordable housing".
