Nob Hill, SF 94109 0218024 6 units · 3 fl · 1908

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 1531-1535 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 1908
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 1908
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 6-unit, 3-story multi-family residential building at 1531-1535 Clay Street in Nob Hill, owned by Danny & Denise Wong, 2012 Fa, has undergone several significant safety and maintenance improvements since its construction in 1908. Most notably, the property completed a mandatory soft-story retrofit in 2018 (Tier 4) at a cost of $60,000, demonstrating compliance with San Francisco's seismic safety requirements. The building's gas safety systems were substantially upgraded in early 2011, with the installation of seismic shutoff valves throughout the building and exterior gas mains, a project valued at $3,000, with revisions completed later that year. Prior to these seismic improvements, the building underwent an important maintenance upgrade with a complete reroofing project in 2010, costing $25,500.

Recent activity near the property has included two street cleaning incidents: a case of human or animal waste in June 2023 and loose garbage debris in September 2024, both of which were resolved by city services. While these external cleanliness issues were promptly addressed, they occurred outside the building itself. The building's documented history shows a proactive approach to both structural safety and maintenance, particularly regarding seismic retrofitting and gas safety systems, with all major improvement projects marked as complete in the city records.

Risk rating

How 1531-1535 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
44thpercentile

Out of 1125 buildings in this neighborhood, 630 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

The three data points that most influenced this building's risk rating — ranked by the weight the model placed on each one.

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.

Neighborhood (ZIP code)

The ZIP code captures local housing market and enforcement patterns that affect all buildings in the area.
