Inner Sunset, SF 94122 1847009 3 units · 2 fl · 1919

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 1435-1437 6Th 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.

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 1919
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 property at 1435-1437 6th Avenue is a two-story, multi-family residential building constructed in 1919 in San Francisco's Inner Sunset neighborhood. The building, which is classified as a Flats & Duplex structure, contains three units and is currently owned by the Helen Y L Fong Survivors Trust. The building's maintenance history shows several notable events: in 2005, there were both permits and a building violation related to repairs needed for rear stairs and decks, which were completed by September 2005 at a cost of $3,500. Routine housing inspections were conducted in 2000, 2005, and 2010, all of which were marked as not active following their resolution.

More recent activity around the property has primarily involved infrastructure issues affecting the surrounding area, with multiple 311 calls in late 2024 regarding pavement defects on nearby sidewalks and curbs, all of which were resolved. Throughout 2023, there were several reports of bicycle lane blockages and issues with animal noise (specifically barking dogs) near the property, though these were external matters. The building's documented history shows regular maintenance of critical structures like stairs and decks, with no significant building violations or safety concerns recorded in recent years. The most recent documented maintenance work on the property was completed nearly two decades ago, with no major structural issues reported since.

Risk rating

How 1435-1437 6Th 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
34thpercentile

Out of 1493 buildings in this neighborhood, 985 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.

Estimated permit spend (past 7 years)

Dollar value of permits pulled at this address — large recent spend can signal deferred-maintenance catch-up.

Building age

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

Construction spend, owner's portfolio

Estimated permit value across all of this owner's buildings.
