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 3951-3953 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.

Built before 1979
Built 1907
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 1907
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 3951-3953 20th Street, owned by the Laval Revocable Trust, has undergone several significant maintenance and compliance processes since its construction in 1907. The property has faced recurring staircase-related issues, with violations and necessary repairs noted in 2002 and 2014, leading to work permits in 2014 to repair back porches and stairs for compliance with prior notices of violation. A complete reroofing project was undertaken in 2011, including the installation of new plywood and asphalt shingles, totaling approximately $14,300 in improvements. The building underwent routine apartment house inspections in 2002, 2009, and a recent one in 2014, which revealed various code compliance matters including the need for carbon monoxide/smoke alarm documentation and structural maintenance affidavits, though these violations have since been resolved.

The property's most recent history shows significant parking-related challenges, with multiple complaints about blocked driveways recorded between 2022 and 2024. There have been at least 14 documented incidents of parking violations in the past two years alone, with officers responding to the majority of these calls and issuing citations in several cases. Other recent maintenance issues in the vicinity include a general cleaning request in August 2023. While the historical building permit and violation records indicate ongoing maintenance and compliance efforts, the building appears to be currently most affected by external issues related to street parking and access, rather than internal building safety concerns, which have been regularly addressed through appropriate permits and inspections.

Risk rating

How 3951-3953 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
36thpercentile

Out of 1278 buildings in this neighborhood, 818 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.

Permit rate, owner's portfolio

Per-building permit rate across the owner's portfolio.

Neighborhood location

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