Buying a Home
San Francisco's residential real estate landscape was largely shaped by the 1930s, but the story of these buildings didn't end there. Most have gone through decades of changes. From complete renovations to actual house-moving (yes, that's a thing in SF!), knowing what's happened to your potential dream home over the years isn't just interesting—it helps you make a smart purchase.
Let's begin with what you'll get right off the bat, the Disclosure Package. Think of this as your property's "life story," prepared by the seller and their agent. It's packed with crucial information about your potential new home, but knowing how to read between the lines is key.
When it comes to understanding the history of a property, first up is the 3R Report (Report of Residential Building Record). This is your official peek into the property's history from the city's perspective. Here's what you'll find:
The legal use of the property (important in a city with lots of in-law units!)
Current zoning details
A history of building permits
While comprehensive in certain areas, it's important to understand its limitations. Here's what you won't see in the 3R Report:
Detailed specifics of completed work
Documentation supporting permits or violations
Building plans
Records of plumbing or electrical permits
Details on unpermitted work
A sample 3R report can be found here.
When selling residential properties with 1-4 units in San Francisco, sellers must provide two key documents (except in special cases like probate sales or bank-owned properties):
Real Estate Transfer Disclosure Statement (TDS)
San Francisco Seller Disclosure
These documents ask sellers to share information about work completed during their ownership and any unpermitted work they're aware of. They must also disclose known material defects or issues.
Keep in mind: these disclosures only reflect the current seller's knowledge. Previous owners' modifications—permitted or not—might remain undocumented.
Home inspectors focus on current conditions rather than historical records. They assess:
Construction quality
Safety concerns
Code compliance
Visible defects
And while they don’t make any official claims regarding past work done, inspection reports can provide valuable clues about a property's evolution—like the appearance of updates, renovations that appear amateurish, or work that doesn't meet current codes. Confirming any such issues requires further research.
Thorough and complete disclosure documents serve as a detailed roadmap of a property's recent history, giving buyers crucial insights for their decision-making, and helping create a clear picture of what buyers are considering purchasing.
While not required, buyers can always choose to conduct deeper research beyond the provided information.
