Rent & eviction protection

Is 1601-1605 20Th 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.

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 property at 1601-1605 20th Street is a two-unit, two-story multi-family residential building with street-level commercial space, built in 1925 and currently owned by Mogannam Nadeem & Violet Tr. The building has undergone several significant updates over its lifetime, with the most substantial work occurring between 2005-2009 including a major electrical upgrade to 200-amp service, rooftop telecommunications installation for T-Mobile, and associated fiber and power modifications. The building's maintenance history includes a reroofing project in 2001, rotted deck repair in 1989, and various sidewalk permits, though one sidewalk defect related to tree roots was reported in July 2024.

Recent residential concerns primarily focus on street-level issues, with multiple reports between 2024-2024 regarding overflowing city garbage cans near the property, and some incidents of graffiti on the mailbox requiring USPS intervention. The building's commercial space has been active as Dave's Food Store, with approved ABC Type 21 licenses for beer/wine/liquor sales occupying less than 15% of the retail space. The only fire incident on record was an alarm malfuntion. The property's maintenance and licensing history shows regular compliance with required permits and inspections, suggesting responsible property management practices, though the frequency of recent sidewalk cleaning issues indicates some ongoing challenges with neighborhood maintenance.

Risk rating

How 1601-1605 20Th 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
59thpercentile

Out of 726 buildings in this neighborhood, 298 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.

Property class: apartment building

Apartment building — this property classification influences expected violation rates.

Building age

Older buildings tend to have more maintenance challenges; SF's pre-1906 earthquake housing stock carries distinct risk.

Neighborhood location

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