Initial analysis

This three-unit residential building located at 40-42 Alvarado Street in Noe Valley is a two-story flats and duplex structure built in 1900, currently owned by Catherine E Conway 2009 Lvg. The property has undergone significant recent improvements, with major renovations completed in 2022 costing $140,000 that included comprehensive updates to the front building's electrical, plumbing, heating, insulation, and drywall systems, as well as kitchen and bathroom remodels. Additional 2022 work included the installation of a new gas furnace system and ducting, bathroom and kitchen renovations with a new tankless water heater, and electrical rewiring in multiple living spaces. Historical records show regular maintenance and upgrades have been performed over the decades, including bathroom/kitchen renovations, electrical updates, and structural improvements, with notable works in 2007-2008 involving rewiring, new 200-amp service installation, and knob & tube removal.

The building's history includes one significant complaint from 1994 regarding hazardous heaters supplying heat to four habitable rooms, though this issue was promptly addressed by November 1994. The property's external environment has experienced periodic issues with street cleaning, loose garbage, and waste management, as evidenced by multiple 311 calls between 2010 and 2024, though these are primarily related to the public space around the building rather than the building itself. Historical permits reveal various improvements, including foundation work on the rear cottage in 1988, exterior rebuilding in 1985, and several modernization efforts throughout the 1990s and 2000s, indicating ongoing maintenance and upgrading of the property systems and living spaces over time.

Risk rating

How 40-42 Alvarado St'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.
