Initial analysis

The property at 1627-1629 9th Avenue is a two-unit, two-story multi-family residential building located in San Francisco's Inner Sunset neighborhood, originally constructed in 1900. In 2004, significant structural work was completed, including a horizontal addition at the rear, raising the building, and excavating a basement to create a four-car garage, with a reported cost of $441,500. The building underwent substantial improvements in the following years, including two separate plumbing projects in 2008 and 2007 involving bathroom and kitchen additions, along with installation of two furnaces and water heaters. The electrical system was significantly upgraded in 2003 with an underground service conversion and 100-amp main service upgrade, followed by additional electrical work in 2007 involving extensive lighting and receptacle installations.

More recently, there have been some concerning issues regarding the property's condition and management. As of July 2024, there is an open complaint regarding illegal construction and permit violations. The property has experienced recurring issues with abandoned vehicles in the vicinity, with four separate incidents reported between 2016 and 2024, though all were resolved when vehicles were found to be gone upon inspection. The property and surrounding area have also faced some maintenance challenges, including reports of property damage in June 2024 (which was cancelled) and loose garbage issues reported in 2017 and 2018. Historical planning records show various proposals for the site, including attempts at a two-lot subdivision and partial demolition with construction of new single-family dwellings, though most of these proposals were withdrawn or otherwise closed without implementation.

Risk rating

How 1627-1629 9Th 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.

Neighborhood percentile
61th percentile

Out of 1493 buildings in this neighborhood, 582 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.

Building age

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

Neighborhood location

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

Building size

Total floor area — a proxy for building scale and the number of systems (plumbing, electrical, HVAC) that can fail.

12-Month severity forecast
No violation 77.2%
Moderate concern 14.5%
Severe concern 8.2%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
