Lake Street, SF 94121 1386023 12 units · 3 fl · 1961

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 278 27Th 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 1961
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 1961
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 12-unit, 3-story multi-family residential building at 278 27th Avenue, owned by Chung Wo Louie Survivors Trust, has undergone several significant improvements since its construction in 1961. Most notably, the building completed a mandatory soft-story retrofit in 2017, which included ground floor reinforcement, installation of shearwalls, and steel moment frames, demonstrating compliance with seismic safety requirements. Recent building improvements include a 2020 renovation that replaced sliding doors and windows, along with exterior siding upgrades, costing approximately $130,000. The building's fire safety systems have required ongoing attention, with multiple violations recorded in recent years regarding alarm systems, exit maintenance, and fire escape conditions. A cluster of four violations was issued in October 2024, including issues with fire extinguishers, blocked exits, and alarm systems, though these were subsequently marked as abated.

The property has a documented history of routine inspections and several corrective actions taken in response to violations. In 2021, a blocked exit and alarm system issue was corrected, while a 2019 exit blockage violation was addressed. The building previously faced multiple fire safety compliance issues in 2003 and 2006, including problems with the fire escape drop ladder, central alarm system, and combustible storage. Historical complaints from 1994-1996 regarding plumbing issues were resolved, and the building's maintenance record shows regular attention to safety features such as handrails, which were updated in 2007 and 2008 to meet code requirements. The property has maintained its soft-story retrofit status as complete, with a Certificate of Final Completion issued, and shows ongoing commitment to address safety violations as they arise, though the frequency of fire-related violations suggests recurring maintenance needs in this area.

Risk rating

How 278 27Th 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
3rdpercentile

Out of 660 buildings in this neighborhood, 640 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.
