For a full-house window swap, that premium alone accounts for $1840-3680 in additional cost.

What window type works best in San Francisco?
Standard double-pane Low-E windows perform well in San Francisco's mild climate — triple-pane is rarely justified by the modest heating loads. The main concern is moisture at window frames — proper flashing and drainage at sills prevents the rot that San Francisco's constant moisture causes.
What pitfalls should I watch for hiring a window installer in San Francisco's HOA neighborhoods?
Be cautious of window replacement contractors in San Francisco who pressure you to sign same-day. Legitimate contractors expect you to get competing bids and will hold their price for 30 days. High-pressure sales tactics correlate with inflated pricing. Any San Francisco contractor who asks for more than 30% upfront before materials are ordered is a red flag. Standard practice is 10-15% deposit, materials-on-delivery payment, and final payment on completion. For older San Francisco homes (average 52 years), beware of window replacement quotes that don't mention code compliance. Modern codes have changed significantly since these homes were built — any work that triggers inspection should be priced with code upgrades included.
