Initial analysis

The 4-unit, 3-story multi-family residential building at 1394-1398 18th Avenue in the Inner Sunset, owned by Alison Judy Yu and constructed in 1948, underwent significant renovations in 2018-2019, totaling approximately $320,000 in improvements. The comprehensive renovation included adding bedrooms, bathrooms, and laundry facilities to all units on the 2nd and 3rd floors, along with complete kitchen and bathroom remodels. The project also featured window replacements, with four windows upgraded from vinyl to aluminum on the third floor, and extensive updates to all units' infrastructure, including rewiring with new electrical systems, plumbing updates, and bathroom remodeling. Two units received tenant buyouts in early 2019, with $47,500 paid to three tenants at 1394 and $70,000 to two tenants at 1398.

The building's recent history shows attention to maintenance and tenant improvements, with no active building complaints since 1999 and routine inspections showing compliance with housing standards. While there have been multiple 311 calls related to the property between 2023-2024, primarily concerning parking issues, these incidents were mostly external to the building itself and included reports of graffiti on public property, which were promptly addressed by city services. The most substantial building improvements occurred in early 2019, including comprehensive electrical upgrades, plumbing work, and the installation of new systems throughout the units, suggesting a significant modernization of the property's infrastructure during this period. The building's maintenance record and recent improvements indicate active property management and investment in tenant amenities, though prospective tenants should be aware of the historical tenant buyouts that occurred during the 2018-2019 renovation period.

Risk rating

How 1394-1398 18Th 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.
