20 Arlington St

Glen Park, SF 94131 6662028 4 units · 2 fl · 1975

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 20 Arlington 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 1975
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 1975
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 property at 20 Arlington Street in Glen Park is a 2-story, 4-unit multi-family residential building constructed in 1975, currently owned by Andrus Partners LLC. The building has undergone numerous renovation and maintenance projects over the past two decades, with significant work focusing on exterior improvements including multiple siding replacements (2011-2014), window upgrades (2014), and stucco repairs (2012). Several building violations related to unauthorized construction and habitability issues have been recorded, including a 2004 complaint about using storage rooms as habitable space and various complaints between 2008-2014 regarding unpermitted construction work, particularly involving bathroom remodels and siding replacements. The most recent building permit of note, filed in 2016 to enclose a light well for kitchen pantry and bathroom modifications, was ultimately cancelled.

The building's maintenance history shows regular upkeep, with completed work including bathroom renovations (2011, 2008), plumbing upgrades, and electrical improvements. Of particular note is the building's status as a residential care facility, with records indicating attempts to expand its capacity from 6 to 15 residents, including a proposal to add two third-floor dwelling units. Recent activity in the vicinity (2024) has primarily involved public infrastructure issues such as sidewalk blockages and graffiti, though these are external to the building itself. The property has maintained compliance with most regulatory requirements, with most violations being resolved through subsequent permits and corrections, though there have been recurring issues with unauthorized construction work leading to multiple complaints and violation citations over the years.

Risk rating

How 20 Arlington 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
23rdpercentile

Out of 364 buildings in this neighborhood, 280 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
