Caravelli Group sold 2340 Filbert Street, a 12-unit apartment building in San Francisco's Cow Hollow, in 2024. Midway through marketing, the city added the building to its mandatory seismic retrofit list. We repositioned the sale, found an all-cash local buyer with seismic retrofit experience, and closed at a price 10% higher per unit than any other 12+ unit sale in Cow Hollow or the Marina that year.

How the sale came together


What kind of building is 2340 Filbert Street?

2340 Filbert Street is a 12-unit apartment building in Cow Hollow, one of San Francisco's most sought-after rental neighborhoods. Its owners had different goals for the sale.


What changed midway through the sale?

Partway through marketing, the city added 2340 Filbert to its mandatory seismic retrofit list. A required retrofit adds cost and uncertainty for a buyer, and it came at a time when many buyers were still cautious after the 2023 banking turmoil. Buyers who had planned on a straightforward purchase now had to price in construction work.


How did Caravelli Group adapt?

We changed the pitch and the buyer pool. Instead of marketing the building to every buyer, we went after buyers who could see the retrofit as an opportunity rather than a risk. Through our network we found a local, all-cash buyer with construction experience and a track record of seismic compliance work, someone for whom the retrofit was familiar ground.

Throughout the sale, we also kept the owners, who had different interests, aligned on decisions so the deal moved forward.


What did 2340 Filbert Street sell for?

2340 Filbert Street sold for $5,650,000 on April 23, 2024, or $470,833 per unit. That was 10% higher per unit than any other sale of a 12+ unit building in Cow Hollow or the Marina in 2024, despite the retrofit requirement.

What does this sale show about selling a building with a seismic retrofit requirement?

A retrofit requirement doesn't have to lower the price if the building reaches the right buyer. Buyers who already do construction and seismic work can price the retrofit accurately, and they often see it as a way to add value. Finding that buyer matters more than discounting for the risk.

Can you sell a San Francisco apartment building that needs a seismic retrofit? Yes. 2340 Filbert Street was added to the city's mandatory seismic retrofit list during marketing and still sold for a top price for its area.
