440 sqft ADU, can only fit a double bed, 2 small nightstands. No bureau. The closet is in the hall. It's also the laundry room.
Christopher Ackerman-Avila approved Christian Spicer's ADUs. He serves as Mayor Todd Gloria's Senior Policy Advisor for Land Use & Housing. BA 2020, masters degree 2021. Hired by City of San Diego 6/21. When he was giving Spicer the mayor's approval, he'd been a city employee for 3 years. That's a lot of authority with little experience. https://www.linkedin.com/in/christopher-ackerman-avila/
This is the only closet for 1-2 renters. Coats, shirts, dresses, shoes, sheets, blankets, personal care products, cleaning supplies, toilet paper. Surfboard, luggage, hobbies? It's also the laundry room. No amenities, no parking. $1,700-$2,500+.
