Rent & eviction protection

Is 147 17Th 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.

Built before 1979
Built 1911

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 1911
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 two-unit residential building at 147 17th Avenue, located in the Lake-Presidio neighborhood, is a two-story flats and duplex structure built in 1911 and currently owned by Tuft Fmly Lvg Tr. The property has undergone several significant maintenance and improvement projects over the years, including a roof replacement in 2001 (cost: $7,600), installation of a new access stair to the second floor wood deck in 2015 (cost: $6,000), and sewer system upgrades in 2009 (complete) and 2022 (water heater replacement, permit expired).

Recent records indicate persistent sewer-related issues, with multiple incidents reported between 2022 and 2024, including a sewage back-up discharge from the side sewer vent in November 2024, and previous incidents in April 2022 and an unresolved sewer vent issue from 2024. The most recent complaints in the area involve a collapsed sidewalk (reported March 2024, currently open), though there have been several successful resolutions regarding street cleaning and parking enforcement. The building's plumbing systems have received attention through various permits, including sewer and house trap work in 2009 and water heater replacement in 2022. Other maintenance activities include a street space and sidewalk permit from 2005.

Risk rating

How 147 17Th 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
41stpercentile

Out of 660 buildings in this neighborhood, 389 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.

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.

Construction spend, owner's portfolio
