Initial analysis

The three-story mixed-use building at 4448-4450 18th Street, owned by D18 LLC, was constructed in 1906 and contains 7 residential units plus ground floor commercial space. The property has undergone several significant renovations and improvements over the past decade, including mandatory ADA compliance upgrades in 2018-2019, replacement of second and third-floor bay windows in 2020, and the installation of a storage mezzanine in the ground floor commercial space in 2014. Electrical and plumbing systems have been updated accordingly during these improvements, with comprehensive kitchen wiring remodels completed in 2005 and various infrastructure upgrades noted in subsequent years.

The building has a history of addressing safety and accessibility concerns, with work completed to meet ADA requirements and resolve a 2011 routine inspection's findings regarding stairs and fire safety issues. Notably, the property has achieved compliance with the City's soft-story seismic safety requirements as a Tier 4 building. While there were several building violations related to fire safety and structural issues noted between 2001-2011, all were resolved, with the most recent structural termite report in 2015 showing minimal (less than 50%) issues. The building's recent history shows regular maintenance and upgrading of systems, with no active building violations or complaints on file since 2011. The surrounding area has experienced typical urban challenges as evidenced by recent 311 calls in 2023-2024, primarily related to street maintenance and debris removal, though these are external to the building's operations.

Risk rating

How 4448-4450 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 1278 buildings in this neighborhood, 920 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.

Number of units

The number of units affects how the model reads complaint and violation totals — more units means more potential sources.

Building age

Older buildings tend to have more maintenance challenges; SF's pre-1906 earthquake housing stock carries distinct risk.

Owner's portfolio size

Number of SF parcels this owner is registered on — larger portfolios have distinct risk patterns.

12-Month severity forecast
No violation 49.3%
Moderate concern 25.9%
Severe concern 24.8%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
