Initial analysis

The two-unit residential building at 124 Douglass Street in Corona Heights, owned by Brian M Carbo, is a two-story flats and duplex structure constructed in 1910. The property has undergone several significant maintenance and infrastructure upgrades over the years, including a complete sewer line replacement from the house foundation to the curb in 2015, reroofing projects in 2004 and 1990, and structural repairs for dry rot and footing stabilization in 1990. The building was subject to a 3R report completion in 1986, though there was an expired permit from 1985 related to physical inspection compliance.

The property has experienced ongoing environmental challenges in recent years, particularly in 2023-2024, with multiple incidents requiring municipal intervention. These include three reports of graffiti (most recently in November 2024), several street cleaning requests, and two encampment-related cases in August 2023 that were subject to federal judicial restrictions on removal due to ADA compliance concerns. A fire complaint in August 2023 was investigated and resolved with corrections made to the identified condition. The building's recent maintenance history shows regular attention to infrastructure needs, though the concentration of recent 311 calls indicates ongoing challenges with public space maintenance and local environmental conditions.

Risk rating

How 124 Douglass 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
62th percentile

Out of 348 buildings in this neighborhood, 132 are predicted to be safer.

2–4 unit flats (class F) are a common SF building type with their own maintenance and complaint patterns.

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.
