Initial analysis

The property at 661 Alvarado Street is a two-unit, two-story multi-family residential building constructed in 1927 in Noe Valley, currently owned by the Yang Thai Family Living Trust. The building has undergone several significant renovations and maintenance work over recent years, with the most substantial improvements occurring between 2019-2020, including a comprehensive interior remodel of kitchens and bathrooms, foundation upgrades with hand-dug piers, and the addition of a new rear deck and powder room in the basement level. The building experienced some challenges in 2016-2018, including moisture issues leading to mold and mildew problems, damaged ceilings and walls, and lead paint concerns, though these violations were officially abated by April 2016. Notable safety-related improvements were made in 2019, including ventilation installation for tankless water heaters and a complete electrical system upgrade.

More recent maintenance activities have focused on exterior upkeep, with multiple reports of graffiti (most recently in November 2023) and parking enforcement issues. The building's maintenance history shows regular attention to structural and safety systems, including furnace replacements and roof work. A withdrawn permit application from 2017 had proposed substantial vertical and rear expansions, though this was not pursued. The property has experienced some minor neighborhood impacts, including a 2020 complaint regarding construction activity during shelter-in-place orders and an excavation-related settlement concern in 2018, though both issues were addressed and marked as not active. The building's most recent permits (2023-2024) suggest ongoing attention to property maintenance, with multiple service requests related to water quality and graffiti removal.

Risk rating

How 661 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.

Neighborhood percentile
92th percentile

Out of 1879 buildings in this neighborhood, 150 are predicted to be safer.

Model explanation

What's driving this score

The three data points that most influenced this building's risk rating — ranked by the weight the model placed on each one.

DBI tenant complaints (past 7 years)

Formal complaints tenants filed with DBI about this building over 7 years.

Neighborhood location

Precise location is a proxy for neighborhood-level risk — some SF blocks have systematically higher DBI activity.

Building age

Older buildings tend to have more maintenance challenges; SF's pre-1906 earthquake housing stock carries distinct risk.

12-Month severity forecast
No violation 88.3%
Moderate concern 9.5%
Severe concern 2.2%
