Lake Street, SF 94121 1379041 15 units · 3 fl · 1963

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 174 20Th Ave 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 1963
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.

15+ years since occupancy
Built 1963
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 15-unit, 3-story multi-family residential building at 174 20th Avenue, owned by Dunmore Associates, has undergone significant renovations and improvements since 2018. The property, classified as a Tier 2 soft-story building, completed its mandatory seismic retrofitting under the California Soft Story Program. Recent substantial upgrades include a comprehensive electrical panel upgrade project scheduled for January 2025 across multiple units (103, 202, 203, 302, 303, 305), following previous improvements to the electrical systems in various units between 2018-2023. The building has seen consistent unit modernization efforts, with multiple apartments receiving kitchen and bathroom renovations, including unit 305 in early 2023, and structural modifications such as bearing wall removals.

The building's safety systems have been a focus of attention, with a new fire alarm system installed in 2019 (per ordinance 165-16) and subsequent upgrades to emergency lighting systems following a violation notice. Two minor fire incidents were recorded, involving a carbon monoxide detector activation (no CO detected) and a malfunctioning alarm system, with no civilian injuries reported. Regular maintenance has included addressing structural issues such as stucco repairs and dry rot remediation in 2018. While there have been several 311 calls regarding the property's surroundings, most relate to external issues like parking and street cleaning, with few pertaining directly to the building itself. The property has maintained compliance with housing inspection requirements, with routine inspections showing no significant ongoing violations.

Risk rating

How 174 20Th Ave'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
6thpercentile

Out of 660 buildings in this neighborhood, 620 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.

Property class (A15)

The assessor's property-class code, which correlates with building type and the violation rates the model expects.
