Initial analysis

The property at 843-845 30th Avenue is a two-story, two-unit multi-family residential building constructed in 1947 in San Francisco's Central Richmond neighborhood. The building underwent significant renovations in early 2017, with substantial improvements including a complete bathroom and kitchen remodel on the third floor ($30,000), addition of washer/dryer facilities ($30,000), and major first-floor enhancements ($40,000) that created a gym, entertainment area, hallway, and powder room, though these modifications were designed to have no visible impact from the street. These improvements were accompanied by necessary electrical and plumbing work, including the relocation of furnaces and electrical meters, with all permits marked as completed.

The building's maintenance history shows attention to infrastructure, with a reroofing project completed in 2017 costing $8,500. While there have been some minor incidents recorded, such as a sewage backup in 2015 (which was resolved) and a parking enforcement call in 2020 that was unable to be validated, these do not appear to be indicative of ongoing issues. A recent fire alarm system complaint in March 2023 was investigated and found to have no merit. A planning record from 843 30th Avenue mentions an unauthorized ground floor modification attempt to add new rooms and a half bath, though this was officially closed as not permitted. The property appears to have been well-maintained and significantly upgraded in recent years, with no major safety or resident experience concerns currently apparent in the available records.

Risk rating

How 843-845 30Th 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.
