Initial analysis

The three-story multi-family residential building at 531-535 Frederick Street, located in the Parnassus/Ashbury Heights neighborhood, is a 4-unit apartment structure built in 1908 and currently owned by Theresa A. Leung Trustee. The building has undergone several significant renovations and maintenance work over the past few decades, including major structural reinforcement in the early 1990s with foundation anchor bolts installation (1991) and brick support reinforcement for the main stairs (1993). A comprehensive electrical system upgrade was completed in 2017 with the installation of a new 200-amp service for the entire building (covering 531, 533, and 535 Frederick Street), and a kitchen remodeling project was executed during the same period that included plumbing upgrades and new appliances. A furnace replacement was completed in 2016 for the top floor flat at #535.

Recent activity at the property includes a noise complaint in June 2024, which was related to entertainment and subsequently closed. The building has undergone regular routine housing inspections (2003 and 2008) which were completed without any noted concerns. Service requests through 311 have included several parking enforcement issues between 2018-2020, primarily concerning vehicles blocking driveways, and some waste management concerns in 2023. A tree planting request was submitted in February 2023, though the Department of Public Works indicated they currently lack the resources to fulfill the request, while confirming the area was an empty basin. The property appears to have been well-maintained, with all major systems upgraded or replaced as needed, and no significant health or safety violations on record.

Risk rating

How 531-535 Frederick 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 526 buildings in this neighborhood, 373 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.

Number of units

The number of units affects how the model reads complaint and violation totals — more units means more potential sources.

Estimated permit spend (past 7 years)

Dollar value of permits pulled at this address — large recent spend can signal deferred-maintenance catch-up.

Owner's portfolio size

Number of SF parcels this owner is registered on — larger portfolios have distinct risk patterns.

12-Month severity forecast
No violation 65.7%
Moderate concern 17.8%
Severe concern 16.5%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
