Rent & eviction protection

Is 186-198 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.

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 10-unit, 2-story multi-family residential building at 186-198 Duncan Street in Noe Valley, owned by Lalena P Goard Lvg Tr, was constructed in 1911 and has undergone several significant improvements in recent years. Most notably, the building completed mandatory seismic retrofitting of its soft-story structure in 2017 (Tier 3), achieving Certification of Completion. Recent safety improvements include the installation of a comprehensive fire safety system in 2020, featuring new control panels, smoke detectors, and emergency pull stations throughout the building, as well as water heater strapping and pipeline repairs in December 2023. The property has also seen substantial unit improvements, including a $100,000 renovation in 2019 of one unit's kitchen and bathrooms, along with electrical and plumbing upgrades.

The building has a documented history of maintenance issues, particularly in the early 2000s, when multiple violations were recorded regarding sanitation, security, and interior maintenance, though these were all abated by 2000. More recent complaints in 2023 raised concerns about stair construction and egress obstruction, though these were marked as not active by March 2024. Several roofing projects have been undertaken, including a $10,000 reroofing job in 2022 and a $19,500 project in 2020. The property has experienced some infrastructure challenges, including plumbing leakage issues in 2010 that affected a neighboring property, though these were promptly addressed. Recent external issues documented through 311 calls include multiple reports of garbage and debris on the property, though these are external to the building itself. The building successfully completed its soft-story retrofit requirements, with supporting documents showing compliance with seismic safety standards, and has undergone various maintenance and improvement works to address both safety and comfort features for residents.

Risk rating

How 186-198 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
0thpercentile

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