Rent & eviction protection

Is 1455 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

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 1455 Clay Street property is a 13-unit, 3-story multi-family residential building constructed in 1922 in San Francisco's Nob Hill neighborhood. The building has undergone significant recent renovations, with multiple units receiving updates between 2020 and 2024, including Units 1, 4, 5, 6, 8, 11, and 12, all of which typically involve bathroom and kitchen remodels, electrical rewiring, and window replacements. However, there are serious current concerns regarding lead contamination and construction safety, with multiple active and recent complaints in December 2024 regarding improper lead containment during construction, lack of proper testing for asbestos and lead, and inadequate dust control measures.

The building has a documented history of maintenance and safety issues, including a significant 2018 violation concerning deteriorating balconies that were deemed a "life safety hazard," though these were subsequently addressed by June 2020. Historical violations from 2009-2016 included various safety concerns such as insecure stairs, security deficiencies, and combustible storage issues, all of which were marked as abated. The property has maintained its soft-story retrofit requirements and has completed the necessary work with a Certificate of Final Completion (CFC) issued. Recent issues also include recurring problems with heating in common areas and pest control, as noted in multiple 2024 complaints.

Risk rating

How 1455 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
9thpercentile

Out of 1125 buildings in this neighborhood, 1024 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.

Model explanation

What's driving this score

Building size

Total floor area — a proxy for building scale and the number of systems (plumbing, electrical, HVAC) that can fail.

Number of units

The number of units affects how the model reads complaint and violation totals — more units means more potential sources.

Building permits (past 7 years)

Number of permits pulled at this address — construction or renovation activity over 7 years.
