Nothing on record for this building in the last seven years. Our model still sees a moderate chance of maintenance problems in the next 12 months, from the owner's wider portfolio and the surrounding area rather than from anything recorded here. No public enforcement record to go on. Walk the building, ask the current tenants how repairs get handled, and get any promises in writing.

Statewide backstop · AB 1482

Even when a building isn't covered by local rent stabilization, the statewide Tenant Protection Act (AB 1482) may still apply. It caps annual rent increases and requires the landlord to state a legal reason to end most tenancies.

Coverage unclear. AB 1482 turns on the certificate-of-occupancy date and property type — confirm the year the building was completed.

AB 1482 does not apply to single-family homes and condos unless owned by a corporation, REIT, or an LLC with a corporate member; to owner-occupied duplexes; or to deed-restricted affordable housing. The Act is in effect until January 1, 2030. Not legal advice — see the California landlord–tenant guide.

Initial analysis

The 3-story multi-family residential building at 453-457 Potrero Avenue in Potrero Hill, owned by Bryan Boot, consists of 3 units and was constructed in 1900. The property underwent significant improvements between 2014-2015, including the installation of a comprehensive fire safety system with sprinklers, monitoring equipment, and heat detectors, along with various plumbing upgrades including gas line reconnections and furnace installations. Multiple building safety improvements were made during this period, including sidewalk repairs and electrical upgrades, though several construction-related complaints were filed between 2014-2015 regarding noise, debris management, and safety concerns during the installation of new units and systems.

Historical violations from 2008-2012 were resolved, including issues related to unauthorized construction and foundation concerns at the rear of the building. The building has experienced recurring maintenance issues in recent years, with multiple 311 calls regarding graffiti (most recently in 2023) and a sewage backup incident in 2022. Two minor fire-related incidents were recorded, one involving a contained cooking fire and another EMS response, with no civilian injuries reported. Recent planning records show the property's development history includes the addition of residential units and modifications to the garage structure, with appropriate permits and notifications being obtained for these improvements. The building's systems have been notably modernized over the past decade, particularly regarding fire safety and electrical infrastructure, though some maintenance and compliance issues have persisted.

Risk rating

How 453-457 Potrero Ave'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

Lower risk — safer than most nearby

DBI rarely finds violations here. Strong maintenance history and a clean complaint record.

Typical — about average for the neighborhood

Some past violations or complaints on record. Worth asking the landlord about any open issues before signing.

Higher risk — riskier than most nearby

Elevated violation and complaint history. DBI has found issues here before and is statistically likely to again.

Neighborhood percentile
37thpercentile

Out of 726 buildings in this neighborhood, 457 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.

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 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.
