Nob Hill, SF 94109 0644019 3 units · 3 fl · 1912

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 1669-1673 Sacramento St 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 before 1979
Built 1912
2 or more units

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 1912
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 1669-1673 Sacramento Street is a three-unit, three-story multi-family residential building located in Nob Hill, built in 1912 and currently owned by Li Mingjing. The building underwent significant renovation and had several controversial modifications between 2013 and 2015, including the installation of new central heaters, kitchen and bathroom remodeling, and electrical system upgrades such as a 200-amp underground service installation with 4 meters and panels. A major period of concern occurred in 2015 when multiple building violations were filed regarding illegal conversions of living spaces, safety hazards, and improper uses of the basement and fourth floor. These violations were allegedly related to unauthorized conversion of spaces into separate guest rooms and R1 transient rentals, resulting in safety concerns around egress, handrails, and occupancy classification. The building experienced multiple complaints regarding construction work without proper permits, including fire safety violations, mold issues, and heating system problems between 2013 and 2015. In addition to these historical concerns, the property has faced ongoing maintenance challenges, as evidenced by multiple 311 calls in 2023-2024 regarding garbage, debris, and graffiti on the building, along with recurring reports of human/animal waste issues outside the property. The building's recent history shows less frequent permit activity since 2017, with the last major permit being for street space and MTA work in 2017, though there have been multiple service calls for graffiti removal and sidewalk cleaning in 2023-2024.

Risk rating

How 1669-1673 Sacramento St'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
41stpercentile

Out of 1125 buildings in this neighborhood, 664 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
