Rent & eviction protection

Is 3531 16Th 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 1905

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 1905
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 three-story, six-unit multi-family residential building at 3531 16th Street in the Eureka Valley/Dolores Heights neighborhood, owned by Sisters LLC, was constructed in 1905 and has undergone significant renovations in recent years. Most notably, the building completed mandatory soft-story retrofit work in 2023, achieving compliance with seismic safety requirements after initial non-compliance was documented in 2019. Recent improvements in 2023 included substantial unit renovations such as a $55,000 kitchen and bathroom remodeling project, along with foundation revisions and electrical upgrades, with work continuing into 2024. Historical records show the building had several violations in 2011 related to fire safety, egress, and combustible storage, though these were promptly abated by April 2011, and a 2020 electrical systems complaint was also resolved.

The property has maintained active upkeep, with regular maintenance including reroofing in 2006 and various unit renovations over the years. Recent tenant-related issues primarily involve external areas, with multiple 311 calls in late 2024 regarding sidewalk cleanliness and parking violations, though these are external community issues rather than building-specific problems. A 2023 complaint regarding concrete work and debris management was investigated but is now marked as not active. The soft-story retrofit project, which started in 2017 and was completed in 2023, was a major infrastructure improvement ensuring the building meets modern seismic safety standards. Regular building inspections and permit activity suggest ongoing maintenance and improvements to the property, with all recent major work being properly permitted and completed.

Risk rating

How 3531 16Th 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
4thpercentile

Out of 1278 buildings in this neighborhood, 1227 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
