This building has 6 novs (7y), at or below the Downtown average of 6.9.

The bar and the rating point different ways because they measure different things: the bar counts DBI violations already on file, the rating forecasts the next 12 months.

Rent & eviction protection

Is 930 Post 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 1925
2 or more units

Property type
Multi-Family Residential

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.

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 44-unit, 6-story multi-family residential building at 930 Post St, owned by SF Multifamily IV Property, was built in 1925 and has undergone substantial renovation work in recent years. Between 2019 and 2020, multiple units received extensive upgrades including new kitchens, bathrooms, and electrical systems, with documented renovations to units 2, 5, 8, 20, 21, and others, totaling several hundred thousand dollars in improvements. The building's safety infrastructure was significantly improved in early 2020 with a $40,000 fire alarm system upgrade, though a current violation for sleeping area requirements was issued in November 2023. Recent maintenance concerns include a January 2024 report of potentially loose concrete segments on the roof chimney, which was addressed by October 2024, and an elevator outage reported in June 2024.

The building has experienced several safety and maintenance issues over its history, including a fire incident in 2016, a mold complaint in 2022, and tenant concerns about renovation work in 2020. Earlier violations from 2001-2009 involved various issues such as fire escape safety, weatherproofing, and interior maintenance, though these were all abated by 2007. The property has undergone multiple plumbing and electrical upgrades, as evidenced by numerous permits, and has maintained active compliance with most building codes. Recent 311 calls for the area primarily relate to sidewalk cleaning and waste removal, suggesting ongoing external maintenance challenges.

Risk rating

How 930 Post 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
2ndpercentile

Out of 448 buildings in this neighborhood, 439 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.

NOV rate, owner's portfolio

Per-building NOV rate across everything this owner manages — high rates signal pattern neglect.
