Initial analysis

The 4-story, 3-unit multi-family residential building at 1280 Hampshire Street in the Inner Mission, owned by Golden Properties LLC, was constructed in 2012 following the demolition of an earlier garage structure. The new construction was completed with an investment of approximately $875,000 and was equipped with comprehensive safety systems, including a fully installed fire sprinkler system throughout the building per NFPA 13 standards (costing $43,725) and a manual fire alarm system with various safety features ($5,000). The building's utilities were properly installed and include six bathrooms, three kitchen sinks, washer/dryer facilities, and 200 electrical outlets with 150 lights and four meters for electrical service.

Several complaints were filed during and immediately after construction in 2012, including concerns about a potentially unauthorized roof deck extension affecting neighboring properties and issues with an old fence being damaged during construction. While these complaints were marked as "Not Active," they indicate some construction-related disputes. The building has generated multiple 311 calls over recent years (2019-2022), primarily related to parking violations (three instances of driveway blocking) and street cleaning issues, particularly regarding loose garbage and an overflowing city garbage can in 2020. Three street space permits were issued in early 2012, and various infrastructure works were completed, including extensive plumbing and electrical installations, suggesting proper compliance with building codes and safety regulations. The building's most recent documented permits and work was completed in 2012, with no significant safety or building code violations recorded in recent years.

Risk rating

How 1280 Hampshire 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
