Rent & eviction protection

Is 15 Nobles Aly 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 1900

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.

15+ years since occupancy
Built 1900
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 15 Nobles Alley, owned by Giampaolo Boschetti and constructed in 1900, has undergone numerous repairs and modifications over recent years. Most notably, in 2024, there are current efforts to remodel the ground floor kitchen and bathroom while converting existing habitable space into an ADU unit, though this permit is still pending approval. The property has faced several maintenance and compliance challenges, including multiple plumbing and electrical upgrades, such as a 2023 fire alarm system upgrade to meet current safety standards and ongoing maintenance issues with water heaters across multiple units. Recent complaints from 2024 indicate several active concerns, including bathroom plaster damage, unfinished bathroom work, and a potentially hazardous garage condition. Previous violations from 2018 had involved various building maintenance issues such as malfunctioning windows, light fixtures, and repairs to walls and ceilings, though these were officially abated by June 2020.

The building's maintenance history shows both ongoing improvements and recurring issues, particularly with plumbing and safety systems. Recent plumbing work in 2024 included bathtub installation in Unit 3, and earlier in 2023, there were concerns about seismic bracing and multiple violations regarding unauthorized construction work. The property has also experienced periodic fire safety inspections, with violations noted in 2015, 2016, and most recently in 2023 related to alarm systems and fire protection equipment access, though these issues were generally resolved. Infrastructure improvements have included various unit renovations, with significant work completed in Unit 2 in 2019-2020 and ongoing efforts to maintain compliance with current building codes. The building's recent history shows active management with multiple permits being filed and completed, though some recent work has generated complaints about unauthorized modifications and quality of workmanship.

Risk rating

How 15 Nobles Aly'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
7thpercentile

Out of 684 buildings in this neighborhood, 636 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
