Initial analysis

The property at 138-140 Lower Terrace is a two-unit, two-story multi-family residential building located in the Corona Heights neighborhood, owned by John Williams. The building underwent significant renovations between 2016 and 2018, including major interior reconfigurations and safety improvements. In 2016, plans were completed to infill walls, create a new fourth bedroom, modify kitchen layouts, and install a new roof deck with hatch access. A more substantial renovation in 2017 involved bathroom conversions, family room modifications, and the addition of fire-rated property line windows at the second and third floors. Multiple permits for plumbing and electrical work were issued during this period, encompassing bathroom additions, water supply line installations, and various kitchen and bathroom remodels.

The building's history includes notable events such as a tenant buyout in December 2015 where two tenants received $112,794 and one tenant received $25,600, and an attempted but withdrawn permit in 2016 for adding an ADU within the first-floor storage area. More recent concerns have centered around parking issues near the property, with multiple citations issued between 2022 and 2024 for illegal parking and driveway blockages. There have also been two notable noise complaints in August 2023 linked to entertainment activities, and a flooding incident reported in December 2022 that was determined to be an internal sewer issue under the homeowner's responsibility. While the extensive renovations of 2016-2018 significantly upgraded the building's facilities, recent parking and utility issues suggest ongoing maintenance challenges.

Risk rating

How 138-140 Lower Ter'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
49th percentile

Out of 348 buildings in this neighborhood, 177 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.

Neighborhood (ZIP code)

The ZIP code captures local housing market and enforcement patterns that affect all buildings in the area.

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 52.7%
Moderate concern 19.9%
Severe concern 27.4%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
