Initial analysis

The 4-unit, 2-story multi-family residential building at 507 Masonic Avenue in the Lone Mountain neighborhood was constructed in 1923 and is currently owned by the Cikes Family Revocable Trust. The property has undergone significant recent improvements, with two major window replacement projects completed in the past year. As of October 2024, 13 retrofit vinyl windows were installed at the rear of the building, and in November 2023, 20 street-facing windows and one rear window were replaced with aluminum-clad and fiberglass options, achieving a U-factor of 0.30 or better. Earlier improvements included a reroofing project completed in 1989.

The building experienced a significant cluster of violations in December 2004, primarily related to fire safety issues, including problems with fire extinguishers, combustible materials in the garage, and concerns about smoke detectors and emergency exits in the apartments. Additionally, violations were recorded regarding wood stairs requiring repair. However, all these violations were successfully abated by February 2005. More recent maintenance concerns have been primarily related to building aesthetics and external maintenance, as evidenced by various 311 calls in 2022-2024 concerning graffiti, sidewalk conditions, and street cleaning. The most recent building inspections on record were routine checks conducted in 2001 and 2004, with the latter leading to the aforementioned violations. The property's recent window upgrade projects suggest active management and maintenance of the building's infrastructure, though the pattern of 311 calls indicates some ongoing external maintenance and neighborhood interaction challenges.

Risk rating

How 507 Masonic Ave'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
21th percentile

Out of 519 buildings in this neighborhood, 410 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.

Neighborhood location

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

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 70.5%
Moderate concern 18.4%
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.
