Initial analysis

The property at 3131-3133 Mission Street is a two-unit, two-story multi-family residential building constructed in 1906, currently owned by Antonio G. Arellano. The building underwent significant modifications in 2010 when the first-floor residential unit was converted into a dental office, involving substantial improvements including a $79,143 bathroom remodel for ADA compliance, installation of dental equipment, and associated plumbing and electrical work totaling over $200,000. This conversion prompted multiple building code violations in 2011 related to unpermitted plumbing work, all of which were resolved by April 2011. The property has experienced several maintenance issues over the years, including heating system failures, security concerns, and various plumbing and appliance problems leading to multiple housing complaints in 2009, all of which were eventually addressed.

Recent activity at the property has primarily consisted of regular municipal service calls, with several reports of street cleaning and debris issues in 2024, though these are related to public thoroughfares rather than the building itself. The building's permit history shows attention to maintenance needs, including a roof replacement in 2005 and various infrastructure upgrades such as a tankless water heater installation in 2011 and HVAC improvements. The property has undergone proper zoning verification and residential conversion processes, confirming its compliance with local regulations. While there were some issues with unpermitted work in the past, these have been addressed, and the building's recent history shows no active violations or complaints directly related to the structure itself.

Risk rating

How 3131-3133 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
80th percentile

Out of 1276 buildings in this neighborhood, 255 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 (ZIP code)

The ZIP code captures local housing market and enforcement patterns that affect all buildings in the area.

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.

12-Month severity forecast
No violation 80.5%
Moderate concern 12.3%
Severe concern 7.1%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
