Rent & eviction protection

Is 1691-1693 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.

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 1948
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 1691-1693 20th Avenue in San Francisco's Central Sunset neighborhood is a two-unit, two-story multi-family residential building constructed in 1948 and currently owned by Moraga Street LLC. This duplex has undergone two significant renovation cycles in recent years, with the most recent comprehensive updates occurring in 2018 involving kitchen and bathroom remodels including new fixtures, cabinets, and appliances, with associated plumbing and electrical work totaling approximately $15,000. Prior to this, in 2015-2016, similar kitchen and bathroom improvements were completed with a total cost of $31,500, featuring new fixtures, lighting, and appliance installations along with electrical system upgrades.

The building has experienced some significant events regarding resident experience, most notably a construction-related noise complaint filed in December 2018, which reported violations of San Francisco's construction noise regulations with work reportedly starting as early as 6 AM and continuing until 11 PM. This complaint was processed through the Building Inspection Division. The property has active maintenance records showing proper oversight of major systems upgrades, including a 125-amp electrical service upgrade completed in 2004. Additional records show multiple street-related incidents near the property including parking violations and waste issues between 2018 and 2022, though these occurred on public streets rather than directly involving the building. A water-related incident was noted in the property records, though no civilian injuries were reported. The building's recent history shows consistent investment in unit improvements, though the 2018 noise complaint represents a notable disruption to resident experience during that period.

Risk rating

How 1691-1693 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
86thpercentile

Out of 814 buildings in this neighborhood, 114 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
