Rent & eviction protection

Is 3801 Market 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 1968

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 1968
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 four-story, five-unit multi-family residential building at 3801 Market Street in Noe Valley, owned by the Lee/Wong Marital Trust, has undergone several significant improvements since its construction in 1968. The property achieved seismic compliance with its Tier 3 soft-story retrofit completed in 2014 (cost: $45,000), and has since prioritized safety upgrades including a full fire alarm system upgrade in 2023 and 2024 (cost: $17,860). Recent electrical improvements include the replacement of a Federal Pacific panel in September 2023, with the panel relocated from the closet to an outside location for improved accessibility and safety. The building's maintenance history shows regular attention to structural elements, including reroofing projects in 1991, 2006, and most recently 2022 (costs ranging from $9,000 to $10,000).

Historical records indicate two routine housing inspections, one in 2003 and another in 2012, which resulted in multiple violations primarily related to fire safety and interior maintenance, including issues with fire escape ladders, lead paint concerns, and security requirements. All these violations were subsequently addressed and abated. The building has maintained an active response to infrastructure needs, as evidenced by a 2023 water heater installation and various street space permits, though some earlier permits from 2002 for deck reconstruction and 1993 for door installation show as expired. Recent 311 calls related to the property have primarily concerned external issues not directly linked to the building's condition, such as sidewalk maintenance, parking violations, and street cleaning matters. The property's recent major system upgrades and timely maintenance responses indicate a proactive approach to building management, particularly in terms of safety and structural integrity.

Risk rating

How 3801 Market 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
51stpercentile

Out of 1879 buildings in this neighborhood, 921 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.

Building size

Total floor area — a proxy for building scale and the number of systems (plumbing, electrical, HVAC) that can fail.
