251 San Jose Ave

Inner Mission, SF 94110 6514019 6 units · 2 fl · 1906

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 251 San Jose 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 1906
2 or more units
6 units
Property type
Multi-Family Residential
Zoning
RM2
Likely rent-controlled. Building age and unit count suggest this property falls under San Francisco's Rent Ordinance.

Based on SF Assessor records. Not legal advice — confirm with the SF Rent Board.

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 1906
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-story, six-unit multi-family residential building at 251 San Jose Avenue in the Inner Mission, owned by Emilio Montalvo 2008 Revoc, has undergone several significant improvements and faced various maintenance challenges since its construction in 1906. Most notably, in 2019, the building completed a mandatory soft-story retrofit costing $100,000 to improve seismic safety, achieving compliance with current building codes. The property has a documented history of water-related issues, including a concerning 2019 complaint about mold growth affecting walls, with reports of water damage and health concerns among residents, though this issue is no longer active. Earlier incidents include fire damage repairs in 2007, during which window replacements were also performed due to fire-related damage.

The building has experienced periodic maintenance issues that required attention, including multiple violations in 2003 related to gas meter safety, exterior door security, and stair repairs, all of which were successfully abated by February 2003. In 2009, there were complaints about damaged carpets and fire safety concerns, though these were resolved promptly. Recent maintenance history shows attention to basic upkeep, with various building permits for repairs and improvements, including a laundry room remodel in 2009 and repairs following a 1994 reroofing project. The property has not had any active building violations since 2003, though there have been multiple 311 calls regarding external maintenance issues such as sidewalk cleaning and tree root damage between 2021 and 2024. An illegal short-term rentals complaint from 2017 appears to have been resolved, with no further activity reported.

Risk rating

How 251 San Jose 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
52ndpercentile

Out of 2380 buildings in this neighborhood, 1142 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.

Building size

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

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)
