Initial analysis

The three-unit multi-family residential building at 2621-2623 18th Street, located in San Francisco's Inner Mission neighborhood, has a documented history dating back to its 1900 construction. The two-story flats and duplex structure, currently owned by Robert Colin Macphee, has undergone several significant modifications and faced various challenges over the years. Major historical work included foundation and basement wall reconstruction in the late 1980s (with two expired permits), staircase installation from main floor to basement in 1998, and the removal of an illegal unit and kitchen in 1996, which was part of a resolution to a flooding incident caused by a sewer backup that had affected multiple units and required significant remediation. Other improvements include a completed reroofing project in 1990 and a now-expired permit for skylight installation and bathroom renovation from 1998.

Most recently, the building's surrounding area has experienced multiple urban challenges, particularly in late 2024, with numerous reports of encampments, abandoned vehicles, and street maintenance issues, though these external conditions have not been directly linked to the building's safety or habitability. The property has had three documented false alarm incidents with its fire detection system, though none resulted in actual fires or civilian injuries. A notable fire-related violation was recorded in 2005 at a nearby address (2601 Mariposa Street) for operating without a fire department permit, though this was not directly associated with the subject property. The building's maintenance history shows generally prompt attention to structural and safety issues, with most permits reaching completion status, though some historical permits are listed as expired.

Risk rating

How 2621-2623 18Th 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 2380 buildings in this neighborhood, 762 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.

Property class: multi-family flat

2–4 unit flats (class F) are a common SF building type with their own maintenance and complaint patterns.

Building permits, owner's portfolio

Permits pulled across all of this owner's buildings over 7 years.

12-Month severity forecast
No violation 54.3%
Moderate concern 35.4%
Severe concern 10.4%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
