Initial analysis

The two-unit residential building at 1415-1417 41st Avenue, owned by Nowell Family Revocable Trust, is a two-story multi-family structure built in 1945 in the Outer Sunset neighborhood. The property has undergone several significant renovations, most notably a substantial 2015-2016 development project that included adding bedroom space to the second and third floors, constructing a rear multipurpose room, and initially installing roof decks. Subsequent to this, multiple revisions were necessary, including the removal of the roof deck and interior stair access in 2022, and adjustments to deck framing and fire guardrails in 2019, with the most recent permit issued in October 2023 indicating recommencement and completion of previously approved work.

The building has seen comprehensive systems upgrades between 2015 and 2024, including a complete electrical overhaul with new 200-amp service installation, replacement of original kitchen and bathroom fixtures, and significant plumbing infrastructure improvements. Most recently, in 2024, the property is undergoing updates to its heating systems with the installation of new furnaces and a combi boiler, along with electrical upgrades to connect the two units more efficiently and implement new recessed lighting. The property has had several maintenance issues reported in recent months, primarily related to parking violations in the vicinity, with multiple calls regarding abandoned vehicles and illegal parking between October and December 2024, though these are external to the building itself. There is currently one open issue from November 2024 regarding pavement defects near the property.

Risk rating

How 1415-1417 41St 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.
