Initial analysis

The Viotti Family Rev Liv Trust owns this two-story, multi-family residential building with commercial space at 4480-4482 Mission St, located in Mission Terrace. Built in 1910, the property contains three residential units and was originally classified as a Flat & Store with 4 units or less. The building has undergone several significant commercial modifications in recent years, with the most notable being the 2016 change from a limited restaurant to a formula retail limited restaurant ("Quickly's"), which included related accessibility improvements and façade modifications. Prior to this, in 2014, substantial ADA compliance work was completed in the commercial space, including the installation of accessible restrooms and new kitchen facilities, with associated plumbing and electrical upgrades totaling approximately $50,000. The most recent major infrastructure work was completed in June 2024 with the replacement of the sewer and house trap systems.

The property has maintained its physical infrastructure reasonably well over the years, with records showing a reroofing project completed in 1994, and various maintenance tasks including signage work in the early 1990s. While there was one electrical complaint regarding a compressor in 2002, this issue was promptly resolved within one day. Recent activity around the property has primarily involved street maintenance and cleaning issues, with multiple 311 calls in 2023-2024 related to garbage, debris, and general cleaning of the street and sidewalk areas, all of which were resolved by city services. A sewer-related flooding issue was reported and resolved in September 2023. The building's commercial space has undergone several ownership and use changes, with proper planning approvals in place to accommodate the transitions between different types of businesses, demonstrating compliance with local zoning requirements.

Risk rating

How 4480-4482 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

Out of 149 buildings in this neighborhood, 118 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 50.6%
Moderate concern 31.1%
Severe concern 18.3%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
