Statewide backstop · AB 1482

California Tenant Protection Act of 2019

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 property at 671 45th Avenue in San Francisco's Outer Richmond neighborhood is a one-story multi-family residential building classified as a Flats & Duplex, containing two units and currently owned by Denis Bouvier 2011 Revoc Fm. The building's legal status as a two-unit residence was officially documented in 2013, following a permit verification process that confirmed previous conversion work completed in 1953. Between 2010-2011, the property underwent significant renovations including kitchen and bathroom remodels on both floors, installation of additional bathrooms, and replacement of front door and window fixtures, with proper permits obtained for electrical upgrades including the installation of a double meter system. However, there is an active complaint filed in February 2020 regarding an allegedly unauthorized in-law unit (Unit A) in the garage area, reportedly containing illegal and hazardous kitchen facilities with gas range, electrical work, and plumbing installations without proper permits. This complaint remains active as of November 2019 observations. The property has a history of regulatory scrutiny for rental activities, including a documented case of illegal short-term rental activity via Airbnb in 2017, though that violation was subsequently closed and appeared to have ceased.

The building's maintenance history shows attention to basic upkeep, with a documented reroofing project completed in 2001, though that permit has since expired. A noise complaint regarding excessive noise was filed in September 2016 and subsequently closed, categorized as informational. The property has undergone several legitimate improvements and modernization efforts over the past decade, as evidenced by the various completed permits, though the active complaint regarding potentially unauthorized modifications raises questions about full compliance with building regulations.

Risk rating

How 671 45Th 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
32ndpercentile

Out of 1040 buildings in this neighborhood, 707 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.

Neighborhood location

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

DBI tenant complaints (past 7 years)

Formal complaints tenants filed with DBI about this building over 7 years.

Building age

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