Initial analysis

The property at 773-777 Oak Street in Hayes Valley is a multi-family residential building owned by Matthew L. Diamond and Jessica, consisting of 3 units plus an ADU, first constructed in 1900. The building has undergone significant recent modifications, with major construction activity initiated in 2019 including plans for a 3-story addition with roof deck, new garage, and driveway improvements. This work, along with the conversion of a first-floor unit to an ADU, was filed under permit number 201908280090. The property has seen substantial improvements since 2013, including a $350,000 rehabilitation project for the rear building, complete electrical rewiring, and updates to plumbing systems with a new boiler installation in 2018. A noteworthy incident occurred in late 2016 when the building received multiple violations for lead paint hazards and structural concerns, though these issues were officially abated by March 2017. The building's maintenance history includes various improvements such as kitchen and bathroom updates, electrical system refurbishments, and the addition of modern amenities like a fireplace and radiant heating system.

Recent activity around the property (2023-2024) primarily involves routine urban maintenance issues such as street cleaning, sidewalk parking violations, and graffiti removal. There have been several general cleaning cases reported through 311 calls, though these are typical for urban environments. The property has received various planning approvals and permits for its renovation and expansion projects, including a CEQA clearance and various plumbing and electrical permits between 2017-2018. Current planning records indicate proposed improvements for adding additional units, although some related permits are still showing as "On Hold" status. The building's transformation from a single-story structure to its current configuration reflects ongoing development efforts to modernize and increase housing capacity on the site, though it's important to note that certain proposed modifications are still in the approval process.

Risk rating

How 773-777 Oak St's risk score is calculated

We trained a model on 7 years of SF DBI inspection data — notice of violation filings, complaint history, and owner track records. It estimates the probability that DBI inspectors will issue a Notice of Violation at this address in the next 12 months. Lower % = safer.

What the score means for you

Grade A–B — Low risk

DBI rarely finds violations here. Strong maintenance history and a clean complaint record.

Grade C — Moderate risk

Some past violations or complaints on record. Worth asking the landlord about any open issues before signing.

Grade D–F — High risk

Elevated violation and complaint history. DBI has found issues here before and is statistically likely to again.

Neighborhood percentile

Out of 1027 buildings in this neighborhood, 51 are predicted to be safer.

Model explanation

What's driving this score

The three data points that most influenced this building's risk rating — ranked by the weight the model placed on each one.

Building age

Older buildings tend to have more maintenance challenges; SF's pre-1906 earthquake housing stock carries distinct risk.

Neighborhood location

Precise location is a proxy for neighborhood-level risk — some SF blocks have systematically higher DBI activity.

Construction type: wood frame

Wood-frame construction (type D) is the most common SF residential type and has specific maintenance risks.

12-Month severity forecast
No violation 91.2%
Moderate concern 7.2%
Severe concern 1.7%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
