San Francisco Home Buyer's Guide: How to Research Property Records Like a Pro

Research Property Records Like a Top San Francisco Realtor

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.

Starting Your SF Property Research: The Disclosure Package 

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.

The 3R Report: The Official Story

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.

Seller-Completed Disclosures: Insider Info on SF Real Estate

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):

1. Real Estate Transfer Disclosure Statement (TDS)

2. 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.

Inspection Reports: Reading for Clues

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. 

Beyond the Basics: Diving Deeper into San Francisco Property History

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.
