Initial analysis

The two-unit, single-story multi-family residential building at 99 Prospect Avenue in Bernal Heights, owned by Harriman Wayne K & Carson J, was constructed in 1908 and has undergone several significant improvements over the years. Most recently, in 2022, the property received substantial maintenance with a $30,000 garage concrete repair project. The building underwent a notable interior reconfiguration in 2007-2009, converting a large studio room into two bedrooms, complete with new partition walls, hallway creation, and bathroom updates including a new shower pan with associated plumbing work. This renovation also included electrical upgrades, adding additional outlets to bedrooms and workshop areas. The property has seen various infrastructure improvements, including a 125-amp service upgrade in 2004, extensive kitchen and bathroom rewiring in 2005, and multiple deck repairs between 2004-2006.

Looking at the most recent activity, there have been several structural maintenance calls in 2024, particularly concerning recreation equipment, with multiple open cases reported between July and November 2024. Other recent concerns include issues with benches on the sidewalk and a tree potentially damaging property in August 2024. The building's permit history shows a pattern of proactive maintenance and upgrades, with most permits eventually reaching completion status, though several from the mid-2000s expired. The property has maintained basic infrastructure requirements over the years, with regular updates to electrical systems and safety features, suggesting ongoing attention to building maintenance and compliance with regulations.

Risk rating

How 99 Prospect 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
97th percentile

Out of 1276 buildings in this neighborhood, 38 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.

Construction spend, owner's portfolio

Estimated permit value across all of this owner's buildings.

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.

12-Month severity forecast
No violation 80.9%
Moderate concern 13.0%
Severe concern 6.1%
