Outer Richmond, SF 94121 1471003 5 units · 2 fl · 1960

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 425 39Th 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 1960

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 5-unit, 2-story apartment building at 425 39th Ave in San Francisco's Outer Richmond neighborhood, owned by Jeffrey & May Kool Survivor, has undergone several significant maintenance and safety improvements since its construction in 1960. Most notably, the building completed its mandatory soft story retrofit in 2018, achieving compliance with San Francisco's seismic safety requirements. Recent infrastructure work includes dry rot repairs at the rear of the building in 2019, window replacements in 2018, and multiple roofing projects in 1990, 2004, and 2016. The building experienced multiple fire safety violations in 2003, including issues with the fire escape ladder, sprinkler systems, and alarm system, though all were resolved by April 2003. A significant plumbing issue occurred in 2004 involving leaks affecting walls, windows, ceilings, and storage areas, which was addressed by February 2005.

The most recent concerns at the property include a sewage backup incident from the side sewer vent in December 2024, which has been resolved. The building has experienced three fire-related incidents on record: an alarm malfunction, a gas leak, and an electrical issue, though none resulted in civilian injuries. Recent 311 calls indicate ongoing maintenance needs in the surrounding area, including landscaping and street cleaning matters. The property was subject to a tenant buyout at the adjacent 443 39th Avenue address in 2022 for $55,900 affecting 2 tenants, though this was for a different building on the same street. The building's maintenance record shows regular upkeep and compliance with major safety requirements, particularly the critical soft story retrofit program.

Risk rating

How 425 39Th 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
18thpercentile

Out of 1040 buildings in this neighborhood, 853 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 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.
