158 Duncan St

Noe Valley, SF 94110 6594016 6 units · 2 fl · 1964

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 158 Duncan 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 1964

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 1964
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 two-story, 6-unit multi-family residential building at 158 Duncan Street in Noe Valley, built in 1964 and currently owned by James M & Chrissa Roukes Lv, has undergone several significant maintenance and safety upgrades over the past decade. Most notably, in early 2023, the building completed a fire alarm system upgrade costing $12,600 to comply with San Francisco Fire Code requirements, following an earlier 2022 electrical modification to install low-frequency sounders in sleeping areas. The building has experienced recurring issues with siding and structural maintenance, with multiple repair projects documented between 2010 and 2020, including significant work in 2019 ($15,000) and 2020 ($13,000) to address damaged siding and window replacements. Historical records show a pattern of fire safety violations and maintenance issues, particularly in the 2000s, including problems with fire extinguishers, smoke enclosure doors, and the central alarm system, though all these violations were resolved by November 2000.

The building has undergone routine housing inspections in 2017, 2008, 2000, and 1999, and while no current building violations are active, historical complaints suggest ongoing attention to fire safety systems has been necessary. Recent activity at the property has primarily consisted of parking enforcement issues, with multiple citations issued in 2023-2024 for driveway blocking. The property management has also addressed basic maintenance needs as evidenced by multiple general cleaning requests being resolved throughout 2023-2024. While the building has experienced various maintenance issues over the years, particularly related to its exterior and fire safety systems, recent years have shown more consistent attention to compliance and infrastructure maintenance, with no active violations or complaints on record.

Risk rating

How 158 Duncan 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
42ndpercentile

Out of 1879 buildings in this neighborhood, 1090 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
