1850 Gough St

Pacific Heights, SF 94109 0641008 40 units · 7 fl · 1931

Nothing on record for this building in the last seven years, but our model still flags a rising risk of maintenance problems in the next 12 months. That forecast comes from the owner's wider portfolio and the surrounding area, not from this building's own record — treat it as a reason to ask questions, not as evidence of a problem. No public enforcement record to go on. Walk the building, ask the current tenants how repairs get handled, and get any promises in writing.

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 1850 Gough 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 1931

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 1931
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 1850 Gough Street property is a 7-story, 40-unit multi-family residential building constructed in 1931, currently owned by Switzer Investment LLC. The building has undergone several significant improvements and faced various maintenance challenges over the years. Most recently, in December 2023, a sound test conducted by Byington Electric revealed decibel levels above 77 in all sleeping rooms, leading to scheduled sample testing with the San Francisco Fire Department. The building has experienced recurring issues with water damage and plumbing concerns, particularly in unit 605, where problems with shower plumbing and water damage were documented between 2014-2017. This unit's maintenance history includes unauthorized plumbing work that prompted multiple housing inspections.

The building's safety systems have received attention over the years, with major upgrades including the replacement of 419 windows in 2001 (permit expired), installation of a new control panel in 2007, and comprehensive life safety system upgrades including smoke detectors, heat detectors, and alarm systems. Fire safety inspections have revealed some recent concerns, including a sleeping area violation issued in November 2023 and a fire extinguisher-related issue in June 2023 (corrected by August 2023). Historical maintenance work includes reroofing in 1996, parapet work in 1991, and various street space permits. The building has experienced issues with exterior maintenance and window problems, particularly noted during 2017 inspections. Recent 311 calls from late 2024 indicate ongoing challenges with garbage management in the vicinity of the property, though these are external to the building itself.

Risk rating

How 1850 Gough 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
16thpercentile

Out of 963 buildings in this neighborhood, 809 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.

Number of units

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

Building size

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

Neighborhood (ZIP code)

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