Current Home Prices and Asking Rents in ZIP Code 94131

That is up 20.6% over the past year and up 7.4% over five years, and the one-year change is the 4th highest of 25 ZIP codes. The Census value above is what owners said their home was worth, averaged over the 2020-2024 survey years. Zillow's figure is a model of what homes would sell for now, so the two are expected to differ, and Zillow's is the one to use for today's market.

The typical asking rent on a new listing in ZIP code 94131 is $5,022 a month as of September 2026, by Zillow's rent index, the 7th highest of 19 ZIP codes and 5% above the citywide figure of $4,784. Asking rent is up 32.4% over the past year. Current tenants here pay a median of $3,064 including utilities, so a new lease costs about 64% more than what the typical renter already pays. That premium is the 4th lowest of 19 ZIP codes. Rent control, long tenancies and subsidized housing all hold paid rents below asking rents, so the widest gaps are where tenants have stayed longest or where much of the stock is below market, and the citywide premium is 93.2%.
