Nothing on record for this building in the last seven years. Our model still sees a moderate chance of maintenance problems in the next 12 months, from the owner's wider portfolio and the surrounding area rather than from anything recorded here. No public enforcement record to go on. Walk the building, ask the current tenants how repairs get handled, and get any promises in writing.

Rent & eviction protection

Is 150 Grattan 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 1927
2 or more units

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 1927
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

Located at 150 Grattan Street in the Parnassus/Ashbury Heights neighborhood, this 4-unit, 2-story multi-family residential building was constructed in 1927 and is currently owned by Patrick J. Stack and Deirdre F. Stack. The building has undergone several significant improvements over the years, most notably a major fire alarm system upgrade completed in 2023, which included installing low-frequency sounders in sleeping areas to meet current safety standards. Recent improvements include a comprehensive kitchen renovation in 2020 that involved cabinet replacement and plumbing upgrades (costing $25,000), along with corresponding electrical work, while the building's infrastructure has been maintained through projects such as a 2011 water main replacement and the installation of exterior lights for security in 2016.

The building's history shows attention to maintenance and compliance, with several routine inspections and prompt responses to violations. In 2002, the property addressed multiple safety concerns including stair repairs, with all related violations being abated by July 2002. A series of complaints and repairs were documented in 2005-2006 regarding roof leaks and security issues, including self-closing doors and furnace repairs, which were also resolved. While there was a termite issue noted in 1990 and some historical violations related to fire safety and security requirements in the mid-2000s, these appear to have been addressed. More recently, the property has generated several parking-related complaints in 2024, though these are street-related issues rather than building-specific concerns. A fire alarm systems complaint was recorded and resolved in 2014-2015, showing ongoing attention to safety systems. The building's permit history demonstrates regular maintenance and upgrades to both interior and exterior elements, with particular attention paid to electrical systems, security lighting, and kitchen facilities.

Risk rating

How 150 Grattan 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
36thpercentile

Out of 526 buildings in this neighborhood, 337 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.

Owner's portfolio size

Number of SF parcels this owner is registered on — larger portfolios have distinct risk patterns.

Building age

Older buildings tend to have more maintenance challenges; SF's pre-1906 earthquake housing stock carries distinct risk.
