Initial analysis

318 Frederick Street is a 6-unit multi-family residential building located in the Haight Ashbury neighborhood, constructed in 1904. The property has undergone several significant improvements over the past decades, most notably completing a mandatory soft-story retrofit in 2017-2019 (Tier 3) to enhance seismic safety. Recent improvements include a bathroom conversion in Unit 6 in 2022, which added a powder room with new fixtures, and various electrical and plumbing upgrades. The building has undergone regular maintenance and updates, including a garage remodel in 2019, foundation work in 2006, and reroofing in 2006.

The building's history includes several routine housing inspections and some violations in 2003-2008 related to fire safety systems, including a fire escape, central alarm system, and self-closing doors, all of which were subsequently abated. A significant incident occurred in 1995 when there was a fire attributed to poor electrical wiring, though this issue appears to have been addressed over the years through various electrical upgrades and improvements. Recent maintenance patterns suggest active management, with most recent maintenance focusing on unit-specific improvements and system upgrades. The property has experienced some infrastructure issues in the surrounding area, including a sewage backup in 2024, though this was promptly addressed. Recent 311 calls related to the property primarily concern street cleaning issues, which have been consistently resolved through standard municipal processes.

Risk rating

How 318 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
68th percentile

Out of 581 buildings in this neighborhood, 186 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.

Building age

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

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 74.6%
Moderate concern 14.2%
Severe concern 11.2%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
