Rent & eviction protection

Is 51 Pierce 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 property at 51 Pierce Street is a two-story, two-unit multi-family residential building located in Hayes Valley, built in 1890 and currently owned by the Rhodes-Andrews Living Trust. The building's maintenance history shows recurring attention to the front stairs, with three separate repair projects documented between 1991 and 2021 addressing both dry rot and general maintenance issues, the most recent of which was completed in early 2021 at a cost of $15,000. Historical permits from the late 1980s and early 1990s indicate attempts at various improvements, including seismic upgrades, though some of these projects were ultimately cancelled or expired.

The building's location has recently experienced some neighborhood challenges, with multiple 311 calls in January 2025 reporting various issues including encampments, graffiti, and debris, though many of these reports were closed due to insufficient information or were determined to be located near but not directly at the property address. Notably, while there is a reference to "plumbing" issues in one January 2025 report, this was related to a fountain in a nearby park rather than the building itself. The property's documented history shows regular maintenance of critical infrastructure, particularly the front stairs, though no major structural modifications or new amenities like those proposed in the 1998 permit for dormers and roof deck have been completed.

Risk rating

How 51 Pierce 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
94thpercentile

Out of 1027 buildings in this neighborhood, 62 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
