Rent & eviction protection

Is 3548-3550 17Th 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 1907

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 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 two-unit residential building at 3548-3550 17th Street in Mission Dolores, owned by Lew Yuk Chun Lee & Yin, was constructed in 1907 and is classified as a Flats & Duplex structure. The building has undergone several maintenance and improvement projects over the years, including reroofing work in 2007 costing $12,300, vinyl siding installation in 1987, and window installations in 1990, though the window permit has since expired. The property has experienced some notable recent issues, particularly concerning postal services - as of November 2024, multiple units (4, 5, 6, and 9) reported problems with broken mailboxes and unresponsive property management regarding key replacement. The building has had various municipal complaints in recent months, including a water heater issue in September 2024 and a currently open sidewalk defect case from October 2024. There's a history of hoarding-related concerns, with one incident in April 2023 being promptly corrected, while a previous allegation from 2015 was determined to have no merit. The only recorded fire incident was a contained cooking fire with no civilian injuries. Recent infrastructure improvements include window installations and vinyl siding, though the expired window permit from 1990 is notable.

Risk rating

How 3548-3550 17Th 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
78thpercentile

Out of 799 buildings in this neighborhood, 176 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.

Neighborhood (ZIP code)

The ZIP code captures local housing market and enforcement patterns that affect all buildings in the area.

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.
