Initial analysis

This three-story, three-unit TIC building located in Mission Dolores was constructed in 1907 and currently owned by Michael McLachlan. The property has undergone significant renovations over the past decade, with the most recent major work occurring in 2020-2021, including bathroom expansions and upgrades in unit 3521, as well as the installation of new bathroom fixtures and a gas insert. Previous improvements include multiple bathroom remodels (2019), kitchen renovations (2015), and electrical upgrades including solar panel installation (2008). Several building permits from 2015-2016 demonstrate substantial interior remodeling work, including the addition of bathrooms and kitchen modifications.

The building's history includes some notable incidents related to construction activities, particularly in 2016 when multiple complaints were filed regarding work being done beyond permit scope, lead paint concerns, and improper containment during renovation work, though these issues appear to have been addressed. There were also routine fire and building violations in 2004-2016 that have since been abated, primarily related to fire safety equipment and handrail requirements. Recent maintenance concerns have been limited to exterior issues, with multiple 311 calls in 2023-2024 reporting graffiti and debris removal needs. The property has experienced three tenant buyouts, with the most recent occurring in December 2015 for unit 3519, totaling $38,200. Parking enforcement issues have been reported in recent months, though these are external to the building's condition.

Risk rating

How 3517-3521 19Th 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 799 buildings in this neighborhood, 439 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.

Construction spend, owner's portfolio

Estimated permit value across all of this owner's buildings.

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 65.9%
Moderate concern 21.5%
Severe concern 12.5%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
