Initial analysis

The two-unit mixed-use building at 4447-4449 Mission Street in the Excelsior neighborhood, owned by the Ghassemzadeh Family Trust, has undergone several significant improvements and faced various maintenance challenges since its construction in 1900. Most recently, in September 2024, a substantial $36,000 reroofing project was completed, indicating ongoing maintenance of the building's infrastructure. The property has experienced multiple fire alarm system incidents, with one violation issued in April 2024, though no actual fires or civilian injuries were reported. The building underwent substantial renovations in 2007, including a complete electrical rewiring of both units, and historical records show attempts to change commercial spaces' use in 2012, though these permits were either cancelled or withdrawn.

The property has faced environmental and safety challenges in recent months, including an open sidewalk defect case from October 2024 related to tree root lifting, and multiple graffiti incidents. A series of 311 calls between July and December 2024 have been logged for various issues, including garbage debris, a damaged tree, and permit parking concerns. The building's commercial space has undergone accessibility improvements, as evidenced by the 2022 installation of a powered door opener to comply with the ABE entrance program. While the property has experienced multiple fire alarm activations, including several false alarms and a cooking fire contained to a container, these incidents have not resulted in any reported injuries or significant damage. The most recent maintenance work, including the 2024 reroofing project and previous ADA compliance measures, suggests active management of the building's upkeep and code compliance requirements.

Risk rating

How 4447-4449 Mission 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
42th percentile

Out of 337 buildings in this neighborhood, 195 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.

Neighborhood location

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

Property class: apartment building

Apartment building — this property classification influences expected violation rates.

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 70.7%
Moderate concern 20.5%
Severe concern 8.7%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
