Initial analysis

The two-unit, single-story multi-family residential building at 823 45th Avenue in the Outer Richmond, owned by Daniel M. Naber, has a documented history dating back to its construction in 1925. The property underwent several significant improvements over the years, including a kitchen remodel in 2006 (completed) that included both cosmetic updates and electrical upgrades with new lighting and dedicated circuits. In 2019, the front entry stairs were replaced at a cost of $7,500. However, the building's history also reveals some concerning moments, particularly regarding building code compliance. A significant violation was recorded in late 2006 regarding an unpermitted second unit in the ground floor behind the garage, which included living spaces and a bathroom with inadequate fire safety features. This violation was not abated until October 2010. In May 2020, a complaint was filed regarding safety concerns with the exterior staircase, although this case was later marked as not active.

Recent activity at the property has primarily involved external maintenance and neighborhood issues, with no active building code violations on record as of October 2023. Multiple 311 calls in 2024, while not directly related to building safety or habitability, indicate ongoing concerns with street and sidewalk maintenance around the property, including reports of garbage and debris, toter management issues, and parking violations. These reports, mostly resolved by city agencies, suggest active neighborhood management but are separate from the building's structural or safety concerns. The building's permit history shows regular maintenance and upgrades, with no recent major construction or remodeling projects on record since the 2019 stair replacement.

Risk rating

How 823 45Th 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
