Rent & eviction protection

Is 1371 47Th Ave rent-controlled?

San Francisco's Rent Ordinance caps rent increases and provides eviction protection for most residential units built before 1979 with 2+ units. Here's how this building scores.

Built before 1979
Built 1960
2 or more units

Likely rent-controlled. Building age and unit count suggest this property falls under San Francisco's Rent Ordinance.

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.

Built 1960
Annual rent increase cap
5% + CPI, max 10%
Just-cause eviction
After 12 months
Local rent control likely takes priority. This building appears to fall under the local ordinance above, which is stronger than AB 1482. Where a local just-cause ordinance applies, its rules govern instead of the state cap.

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 8-unit, 2-story multi-family residential building at 1371 47th Avenue in the Outer Sunset, owned by Chu Paul T F & Fong-chu Chr, has undergone significant improvements and faced several maintenance challenges since its construction in 1960. Most notably, the building completed a mandatory Tier 4 soft-story retrofit in late 2016 (cost: $99,800), which included structural improvements such as the relocation of steel moment frames and shear walls, along with new electrical infrastructure in the foundation. During the same period, the property underwent modifications to its garage access, including the installation and relocation of a new garage door (cost: $4,000) through multiple permits completed between late 2016 and early 2017.

The building's maintenance history reveals ongoing concerns with safety and habitability. As of April 2023, there are several active building violations that require attention, including issues related to smoke detection systems, fire extinguisher maintenance, lead paint compliance, and the condition of fire escape drop ladders. Earlier concerns have included water damage and potential mold issues (2014), peeling paint inside and outside the building (2012), and various safety violations documented in 2002, including problems with fire escape ladders and gas utility shutoff tools. The most recent inspection in 2023 has highlighted multiple safety and maintenance issues that remain unresolved, though the building has successfully completed important structural improvements such as the soft-story retrofit. Historical records also show attention to security improvements in 1985, suggesting ongoing efforts to maintain and upgrade the building over time.

Risk rating

How 1371 47Th 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
17thpercentile

Out of 632 buildings in this neighborhood, 525 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.

NOV rate, owner's portfolio

Per-building NOV rate across everything this owner manages — high rates signal pattern neglect.

Neighborhood location

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