Cities adjust building codes to allow micro apartments
San Francisco, where a growing number of residents are being priced out of the housing market by a revived high tech economy, is the latest city to consider so-called “micro apartments.” City officials may adjust the building code to allow the smallest housing micro-units of any US city—150 sf of living space —220 sf when you add the bathroom, kitchen, and closet. San Francisco’s current code requires apartment units to be at least 290 sf.
