Inner Sunset, SF 94122 1739011 3 units · 3 fl · 1900

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 1255-1257 11Th 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.

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 Huang Family Trust property at 1255-1257 11th Avenue is a three-unit, three-story multi-family residential building located in San Francisco's Inner Sunset neighborhood. Built in 1900, this flats and duplex-style structure has undergone several significant renovations and improvements over its lifetime, including a notable horizontal addition completed in 1990 at a cost of $240,000, and most recently, a reroofing project completed in 2014 costing $5,000. The building experienced a period of maintenance and safety upgrades in 1992 when fire sprinklers were installed, and miscellaneous violations were addressed following a Dahi inspection report.

The property has a documented history of code violations and complaints, with the most recent routine inspection occurring in 2010, during which multiple issues were identified including problems with gas utility shutoff tools, gas meter instructions, damaged ceilings, and garbage receptacle placement, though all were subsequently abated by October 2010. Since then, the building has not shown any major violations or complaints related to building safety or maintenance. Recent activity at the property has primarily involved parking-related issues, with multiple complaints regarding blocked driveways between 2021 and 2024, resulting in several citations being issued to offending vehicles. Most recently, there was a documented water main issue in October 2024, which was promptly addressed by city services. While the building has had its share of regulatory interactions over the years, particularly in the early 1990s and 2000s, these appear to have been resolved through proper channels, and more recent history shows improved compliance with housing codes and regulations.

Risk rating

How 1255-1257 11Th 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
25thpercentile

Out of 1493 buildings in this neighborhood, 1120 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.

Building age

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

Estimated permit spend (past 7 years)

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

Building permits (past 7 years)

Number of permits pulled at this address — construction or renovation activity over 7 years.
