Rent & eviction protection

Is 1671-1675 Clay 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 1922
2 or more units

Property type
Multi-Family Residential

Likely rent-controlled. Building age and unit count suggest this property falls under San Francisco's Rent Ordinance.

Based on SF Assessor records. Not legal advice — confirm with the SF Rent Board.

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 1922
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 13-unit, three-story apartment building at 1671-1675 Clay Street in Nob Hill, constructed in 1922, has undergone significant improvements and renovations in recent years, with particular emphasis on unit upgrades and safety systems. Between 2019 and 2022, multiple residential unit renovations were completed, including kitchen and bathroom remodels, with work performed in Units 1, 4, 5, 6, 8, 12, and others, typically involving kitchen relocations, bathroom rehabilitations, and washer/dryer installations. Building-wide improvements included a comprehensive fire alarm system upgrade in 2021 to meet SF Fire Code requirements (SFFC 1103.7.6.1), installation of low-frequency sounders in sleeping areas, and subsequent updates to the fire alarm system components in 2022. The building has achieved compliance with San Francisco's soft-story retrofit requirements as a Tier 3 building, with work completed and a CFC issued.

The property has a history of fire safety concerns, with multiple fire code violations recorded in 2017 and 2020, including issues with alarm systems, extinguishers, blocked exits, and minimum egress lighting, though these violations were eventually abated or corrected. In March 2020, there were complaints about non-permitted construction work during the COVID-19 shelter-in-place period, and in January 2020, there were concerns about heavy construction work occurring on Saturday mornings. The building's maintenance history shows attention to basic infrastructure, with a sewer pipe replacement in 2009 and various plumbing and electrical upgrades. Historical violations from 2011-2014 included issues with security, lighting, and appliances, which were addressed during that period. The most recent fire-related incidents registered were false alarms or detector malfunctions, with no civilian injuries reported.

Risk rating

How 1671-1675 Clay 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
24thpercentile

Out of 1125 buildings in this neighborhood, 855 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
