1377 18Th Ave

Inner Sunset, SF 94122 1773004C 4 units · 2 fl · 1968

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.

Rent & eviction protection

Is 1377 18Th 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.

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 4-unit, 2-story multi-family residential building at 1377 18th Avenue in the Inner Sunset, owned by Louie Family Trust, has undergone several maintenance and improvement projects since its construction in 1968. The most significant recent renovation occurred in 2018, when Unit #1 received a comprehensive kitchen and bathroom remodel, including new cabinets, plumbing and electrical fixtures, with associated improvements to lighting, switches, receptacles, and installation of new appliances and smoke detectors. In 2019, the building underwent window upgrades, with the replacement of four large windows on the front of the building, costing $10,000. Earlier improvements include a street-facing window replacement project, attempted in 2002, and a roofing project from 1991, though both of these permits expired without confirmation of completion.

The building has experienced three routine housing inspections over the years, with the most recent in 2011 revealing multiple safety and compliance issues that were subsequently addressed, including the need for fire safety improvements (e.g., fire extinguisher servicing, smoke detector installations), plumbing modifications (e.g., hot water heater seismic bracing), and sanitation matters, all of which were abated by August 2011. The 18th Avenue property has been the subject of several recent parking-related incidents, with multiple reports of driveway blocking between 2023 and 2024, though most of these complaints were either invalidated or resulted in citations. Additionally, there have been two reported street cleaning issues in 2023 and 2024, including one instance involving loose garbage. The building's compliance history shows that while there have been various violations and complaints in the past, all documented issues have been resolved, with no active violations currently on record.

Risk rating

How 1377 18Th 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
31stpercentile

Out of 1493 buildings in this neighborhood, 1030 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.

Neighborhood location

Precise location is a proxy for neighborhood-level risk — some SF blocks have systematically higher DBI activity.

Neighborhood (ZIP code)

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