Hayes Valley, SF 94117 0846001 5 units · 3 fl · 1895

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 257-263 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.

Built before 1979
Built 1895
2 or more units

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

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 1895
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, five-unit building at 257-263 Pierce Street in Hayes Valley, owned by Boschetti Giampaolo, was constructed in 1895 and has experienced several concerning incidents in recent years. Most notably, in July 2025, there was a gas leak incident at the property that required emergency response but fortunately resulted in no civilian injuries or fatalities. The building's maintenance and environmental conditions have come under scrutiny more recently, with multiple service requests in July 2026 alone, including reports of shrubbery obstructing visibility, human waste or urine, and general garbage and debris issues. This followed a series of other maintenance and aesthetic concerns earlier in 2026, including resolved cases involving loose garbage, yard waste, graffiti on a power line pole, and abandoned toter violations. The building's service request history shows a notable increase in reported issues, with a total of 171 service requests logged over the past seven years, though these are primarily concentrated in the most recent 12-18 month period. The only building permit on record from the past seven years, issued in June 2019, was related to street space usage.

Risk rating

How 257-263 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
58thpercentile

Out of 1027 buildings in this neighborhood, 431 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
