Initial analysis

The two-unit residential building at 1530-1532 Mason Street in North Beach, owned by Alan M & Kara A Mark Jt Rev, is a two-story flats and duplex structure built in 1908. The property has maintained a relatively stable history, with only one recorded building permit from September 2017 for street space use at a minimal cost of $1.00. The location has experienced recurring street cleanliness issues, particularly between 2019 and 2024, with multiple incidents requiring municipal intervention for garbage, debris, and human or animal waste cleanup. Notable recent incidents include an offensive graffiti case in April 2023 and a glass-related debris issue in October 2024, both of which were resolved by city services.

The surrounding area has seen some transient vehicle-related incidents, with two abandoned vehicle reports in September 2019 and December 2019, though both vehicles were gone by the time authorities arrived. The most significant recent event related to tenant relocation occurred on July 7, 2023, when a buyout was processed for 1526 Mason Street in the amount of $4,900 for one tenant, though this address is slightly different from the primary building address. While the property has experienced various maintenance and cleanliness issues in the surrounding area, particularly with street conditions, directly correlating these to the building's internal conditions is not possible based on the available data. The most recent permit on record is the 2017 street space permit, representing the only documented structural modification or use change in recent years.

Risk rating

How 1530-1532 Mason 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 362 buildings in this neighborhood, 72 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 location

Precise location is a proxy for neighborhood-level risk — some SF blocks have systematically higher DBI activity.

Building size

Total floor area — a proxy for building scale and the number of systems (plumbing, electrical, HVAC) that can fail.

Building age

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

12-Month severity forecast
No violation 73.3%
Moderate concern 10.4%
Severe concern 16.2%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
