Initial analysis

The three-unit multi-family residential building at 127-129 Beaumont Avenue in the Lone Mountain neighborhood is a two-story flats and duplex structure built in 1936, currently owned by Mitchell D. Smith. Over the past two decades, the property has undergone several significant improvements, with the most substantial recent work occurring in 2017-2018, including a comprehensive bathroom remodel on the street level ($40,000), electrical upgrades replacing knob and tube wiring, and installation of new heating systems. Notable maintenance work included balcony repairs in 2014 ($3,000), window replacements and vinyl siding installation in 2012 ($4,750), and roof work involving modified bitumen application in 2002.

A concerning incident occurred in February 2023 when a complaint was filed regarding sewage or graywater flow from the property, though this issue was marked as not active on the same day. Earlier building complaints from 1997 documented heating and sealing issues, which were promptly addressed. The property underwent significant modernization between 2010-2012, including sewer line work, water heater replacement, and various electrical improvements such as kitchen wiring updates and sub-panel relocations. Historical 311 calls primarily relate to street and parking issues near the property, with no direct connection to building conditions. Records indicate a tenant buyout at 129 Beaumont Avenue in August 2017 involving four tenants and a payment of $85,000.

Risk rating

How 127-129 Beaumont 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.
