1395 40Th Ave

Outer Sunset, SF 94122 1795015B 4 units · 2 fl · 1954

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.

Rent & eviction protection

Is 1395 40Th 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 1954

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.

15+ years since occupancy
Built 1954
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 multi-family residential building at 1395 40th Avenue in the Outer Sunset, owned by Wei-chen & Fengying Chen Fm, has experienced several significant maintenance and safety issues over its history. The two-story, four-unit building, constructed in 1954, has undergone various repairs and upgrades, including a $4,500 window replacement project in 2006 that upgraded aluminum windows to vinyl in units 1, 2, and 3, and individual window repairs in unit 4. The building faced a series of concerning moisture-related problems in early 2006, including mold issues in multiple units and a roof leak that resulted in flooding and appliance damage, following which extensive repairs were undertaken including window replacements and hardwood floor repairs. The property has a history of fire safety concerns, particularly evident in 2001-2002 when violations were recorded for fire escape-related issues and missing smoke enclosure door closers, though these were all abated by February 2002. Additional maintenance work included a $6,000 reroofing project and electrical system upgrades in 2002, which brought the building's electrical infrastructure up to code with a new 200-amp main service and five electric meter sockets and panels.

More recent history shows the building has remained active in terms of maintenance and compliance, with routine inspections occurring regularly, including a 2011 inspection that had no active violations. The property is currently facing ongoing parking-related issues, as evidenced by multiple 311 calls for parking violations near the property between September and December 2024, though these are not directly related to building conditions or safety. The building's maintenance history suggests a pattern of prompt response to violations and necessary repairs, with all documented violations being officially abated. The most recent building-related issues have primarily centered around infrastructure upgrades and routine maintenance, indicating improved overall building condition but also highlighting some ongoing challenges with exterior drainage and weatherproofing systems.

Risk rating

How 1395 40Th 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
36thpercentile

Out of 632 buildings in this neighborhood, 404 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.

Neighborhood (ZIP code)

The ZIP code captures local housing market and enforcement patterns that affect all buildings in the area.

Neighborhood location

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