501 Grove St

Hayes Valley, SF 94102 0807001 10 units · 2 fl · 1924

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 501 Grove 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 1924
2 or more units

Likely rent-controlled. Building age and unit count suggest this property falls under San Francisco's Rent Ordinance.

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 1924
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

501 Grove Street is a two-story, 10-unit multi-family residential building in Hayes Valley, constructed in 1924 and currently owned by Michael H. Elbaz. The property has undergone several significant safety and structural improvements, including a completed soft-story retrofit in 2015 that strengthened the ground-level garage/storage area, and the removal of a seismic-hazardous brick chimney. More recently, electrical upgrades are ongoing, with a permit issued in February 2024 for replacing the Federal Pacific disconnect switch and upgrading grounding to code compliance. The building has had some recent maintenance issues, with multiple 311 calls in late 2024 regarding sidewalk cleaning and illegal parking, though most were resolved promptly.

The property has a complex history regarding unauthorized short-term rentals, with multiple vacation rental complaints filed against units 3, 4, 9, and 10 between 2017 and 2019, which were subsequently abated. In 2020, a significant project to add 4 ADUs at the first floor was proposed but ultimately cancelled. Historical records show routine safety inspections in 1999, 2001, and 2010, and two fire extinguisher-related complaints in 2007 and 2017, both of which were promptly corrected. The building's most recent fire incidents involved a carbon monoxide detector activation with no CO detected and a person in distress situation, neither resulting in civilian injuries. While the building's major seismic and safety improvements have been completed, there is ongoing monitoring of street-related issues in the surrounding area.

Risk rating

How 501 Grove 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
25thpercentile

Out of 1027 buildings in this neighborhood, 770 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.

Neighborhood (ZIP code)

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

Building size

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