140 Wood St

Lone Mountain, SF 94118 1092025 6 units · 3 fl · 1960

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.

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 140 Wood 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 1960
2 or more units

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.

Built 1960
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 140 Wood Street in Lone Mountain, owned by the Jang Family Trust, was constructed in 1960 and has undergone several significant events over its lifetime. Most notably, in October 2023, a mandatory fire alarm upgrade was filed to meet current fire marshal codes, including updating the fire alarm panel, adding horns in units, and installing a wireless communicator. The building has experienced multiple fire alarm-related incidents, including false alarms, malicious false alarms, and a malfunction in 2017 that required correction. A documented instance of mold and dry rot was reported in 2016, and in 2005, the property underwent reroofing work costing $10,500.

The building has a history of various housing code violations, particularly in late 2002 and late 2005, though all these issues were resolved by November 20, 2002. Violations from 2002 included problems with self-closing doors, gas metering equipment, and plumbing/electrical systems, while 2005 violations noted issues with ceiling repairs and fire escape ladder maintenance. There was also a concerning report in 2002 of black smoke coming from a heating vent. The building has experienced numerous street-related issues in recent years, with multiple reports of abandoned furniture and debris on the sidewalk between 2022 and 2025, though these were addressed promptly. Two parking enforcement incidents related to driveway blocking were reported in 2020. The property's most recent documented building permit activity is from October 2023, focusing on crucial fire safety upgrades, which suggests ongoing attention to building safety systems.

Risk rating

How 140 Wood 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
11thpercentile

Out of 519 buildings in this neighborhood, 462 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.

Building age

Older buildings tend to have more maintenance challenges; SF's pre-1906 earthquake housing stock carries distinct risk.
