Inner Sunset, SF 94122 1741007 3 units · 2 fl · 1909

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 1241-1243 9Th 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 1909
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 1241-1243 9th Avenue is a two-story, three-unit multi-family residential building with storefront space, constructed in 1909 in the Inner Sunset neighborhood. The building has undergone significant improvements in recent years, with major renovations taking place in 2018 including a comprehensive Unit A remodel ($250,000), window replacements ($80,000), and a complete reroofing ($18,000). The building's infrastructure has seen important updates, including sewer lateral replacement and bathroom/kitchen renovations in 2018, followed by a gas line replacement in September 2024. Electrical improvements were made in 2018 with an apartment re-wire and sub-panel replacement.

Recent concerns have emerged regarding the property's exterior and surrounding areas, with several 311 calls in 2024 related to sidewalk defects, garbage issues, and other public health matters. Notably, there is an open environmental health complaint filed in December 2024. Historical improvements include the installation of a grease trap in 2013 and various street space permits issued between 2007 and 2019. The building's maintenance record shows regular upkeep and modernization efforts, with recent plumbing work focusing on bathroom, kitchen, and laundry facilities. Planning records confirm several approved modifications, including window replacement and interior reconfigurations, as well as approvals for continuing existing retail restaurant use. The property's recent renovation history suggests ongoing investment in building maintenance and improvements, though the recent environmental health complaint and several open service requests indicate some current building and neighborhood challenges.

Risk rating

How 1241-1243 9Th 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
14thpercentile

Out of 1493 buildings in this neighborhood, 1284 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
