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 1641-1647 Noriega 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.

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 1951
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 Ng Family Revocable Trust owns this two-story, four-unit multi-family residential building with commercial space, constructed in 1951 at 1641-1647 Noriega Street in San Francisco's Central Sunset neighborhood. The property has undergone significant improvements and maintenance since 2002, with substantial commercial tenant improvements completed in 2012-2013 including accessibility upgrades, bathroom installations, and interior modifications totaling approximately $151,000. Major infrastructure upgrades were completed in 2013, including a 400-amp electrical service upgrade with multiple meters installed, new central heating system, and plumbing work for accessible restrooms. More recent maintenance includes sewer line replacement work in 2018, indicating ongoing infrastructure upkeep.

The building has experienced multiple waste management issues in recent months, with ten separate reports of abandoned garbage, debris, and electronic waste documented between November 2024 and January 2025, though all these cases were resolved by city authorities. A street light outage was also reported and resolved in November 2024. While the property has maintained its structural and systems components through regular upgrades and repairs, the recent pattern of waste management issues suggests external environmental challenges in the immediate vicinity, though these are not directly related to the building's structural or systems conditions. Historical records show earlier improvements including ceiling framing replacement in 2003 and various unit remodels throughout the 2000s, demonstrating consistent property maintenance over time.

Risk rating

How 1641-1647 Noriega 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
12thpercentile

Out of 814 buildings in this neighborhood, 716 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
