838 Valencia St

Mission Dolores, SF 94110 3597073 4 units · 1908

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 838 Valencia 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 1908

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.

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 four-unit residential building at 838 Valencia Street in Mission Dolores, owned by Colbert T Dare & Patty Chu, has a documented history of maintenance and compliance issues dating back to 2010. The property, which was built in 1908, experienced significant violations in September 2010, when multiple issues were identified including problems with interior surfaces (floors, ceilings, and walls), plumbing, electrical systems, and fire safety equipment. These violations were all resolved by October 25, 2010. In 2011, there were reports of mold, bathroom damage, and carpet issues, while 2012 brought complaints about unauthorized modifications including an alleged fifth unit and an exterior wood utility ladder, both of which were addressed by July 2012. Earlier structural concerns were documented in 2004 when repairs were made to address dry rot in the back stairs, and in 2012 when handrail modifications and window replacements were completed in response to another complaint.

The most recent building activity primarily consists of street maintenance and cleaning issues, with several 311 calls between 2022-2024 regarding garbage, toter management, and general cleaning in the vicinity of the property. These external maintenance matters were generally resolved promptly by city services. The property's historical record shows a pattern of maintenance issues largely centered on safety compliance and basic infrastructure, though these problems appear to have been addressed through the necessary permits and corrections. As of the latest available data, there are no active building violations or pending complaints, and no fire incidents have been recorded at the property.

Risk rating

How 838 Valencia 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
55thpercentile

Out of 799 buildings in this neighborhood, 360 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
