Rent & eviction protection

Is 3649 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 before 1979
Built 1964
2 or more units
33 units
Property type
Multi-Family Residential
Zoning
RM1
Likely rent-controlled. Building age and unit count suggest this property falls under San Francisco's Rent Ordinance.

Based on SF Assessor records. Not legal advice — confirm with the SF Rent Board.

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 1964
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

3649 Market Street is a six-story, 33-unit multi-family residential building constructed in 1964, currently owned by Ralston Capital Sf Multifam. The building has undergone significant improvements over the past decade, including the installation of electric vehicle charging stations in 2018, multiple unit renovations, and facade updates. Recent concerns include recurring water issues, with a notable complaint in February 2023 about leaks and mold in the third-floor hallway, along with a 2020 complaint regarding water leakage affecting the neighboring property. The building has experienced several maintenance challenges, including an elevator outage in January 2015, deck and balcony concerns in 2010, and various water-related issues between 2009-2015.

Of particular note are the recent fire safety concerns, with violations issued in 2022 and 2023 related to alarm systems and sleeping area requirements, though some have been corrected or abated. The building has documented three fire incidents, including an elevator rescue, cooking fire, and carbon monoxide incident, though none resulted in civilian injuries. Historical records show multiple renovation projects, including kitchen and bathroom remodels (notably in unit 203), deck additions, and washer/dryer installations in several units. The property has maintained active compliance with building permits, completing various maintenance works including roof repairs, facade improvements, and utility upgrades. While there is a history of maintenance issues, the building has shown responsiveness to violations and completed numerous improvements to enhance resident amenities and safety.

Risk rating

How 3649 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
0thpercentile

Out of 1278 buildings in this neighborhood, 1278 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.

Building size

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

Neighborhood location

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