Rent & eviction protection

Is 178 Portola Dr 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.

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 1971
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 property at 178 Portola Drive is a three-story, two-unit multi-family residential building located in Twin Peaks, owned by Mark S Young and constructed in 1971. The building has undergone several significant improvements over the years, with the most substantial renovation occurring in 2010-2011 when a garage space was converted into a media room with bathroom (314 square feet) including comprehensive electrical work and plumbing installation, costing approximately $39,000. Earlier improvements in 2007 included exterior window replacements, front door updates, stucco repairs, and an important electrical system upgrade to 200 amps with three meters. A deck repair project was completed in 2008, though a complaint was filed in 2006 regarding various issues including a leaking roof, deck repair concerns, cracked windows, and an electric gate malfunction, which were purportedly abated within a month.

Recent history of the property shows no active building code violations, but it experienced some temporary issues in early 2024 with multiple reports of garbage and debris on the street/sidewalk near the property, all of which were resolved by city services. Of particular note is a historical compliance issue regarding short-term rentals; the property was identified and cited for illegal short-term vacation rentals in 2013 and 2014, with the second violation specifically mentioning previous infractions at a different location, though these activities have since been confirmed as abated.

Risk rating

How 178 Portola Dr'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
95thpercentile

Out of 172 buildings in this neighborhood, 9 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
