Initial analysis

The three-unit multi-family residential building at 345-347 Frederick Street, owned by Victoria Aniko Reierstad, was constructed in 1900 and spans two stories in the Parnassus/Ashbury Heights neighborhood. The property has undergone significant renovations between 2015-2016, including kitchen remodels in units 345 and 347, bathroom upgrades, electrical system improvements, and the installation of three gas furnaces. A major concern persists regarding unauthorized construction, as evidenced by a 2020 complaint about an unpermitted rear extension and roof terrace that overlooks neighboring properties, following a similar 2017 complaint about an unauthorized second-floor deck construction after neighbor objections. Historical issues include multiple building violations from 2000-2005 related to safety and fire requirements, including problems with fire safety equipment and unauthorized construction of a rear addition and retaining wall. The building has undergone numerous permit renewals and inspections from 2015-2017, indicating ongoing efforts to bring the property into compliance, though some permits were completed while others were cancelled or expired. Recent 311 calls from 2023-2024 primarily relate to exterior maintenance issues like graffiti and waste management, though these do not directly affect building safety or habitability.

Risk rating

How 345-347 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
17th percentile

Out of 526 buildings in this neighborhood, 437 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 size

Total floor area — a proxy for building scale and the number of systems (plumbing, electrical, HVAC) that can fail.

DBI tenant complaints (past 7 years)

Formal complaints tenants filed with DBI about this building over 7 years.

Building age

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

12-Month severity forecast
No violation 31.3%
Moderate concern 20.6%
Severe concern 48.1%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
