Noe Valley, SF 94131 6563050 2 units · 3 fl · 1979

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.

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 1979
Annual rent increase cap
5% + CPI, max 10%
Just-cause eviction
After 12 months
May be covered by AB 1482. The building is old enough for the statewide rent cap (5% + regional CPI, capped at 10% per year) and just-cause protection after 12 months of tenancy.

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 three-story multi-family residential building at 4157 26th Street in Noe Valley, owned by McCormick Properties LLC, has experienced a notable pattern of parking-related issues over the past year. From October 2023 to January 2025, there have been multiple documented incidents of vehicles blocking driveways and parking on sidewalks in the vicinity of the property. Of particular significance is the pattern of driveway blocking incidents in late 2023 and throughout 2024, with at least seven such incidents recorded, though some were resolved without citation. These include documented cases involving specific vehicles, such as a white Toyota 4Runner, a blue Volvo, and others, with citations being issued in several instances. The most recent incident, from January 2025, involves a complaint about a BSM-related issue that remains open.

In addition to parking issues, there was one noise complaint related to barking dogs recorded in October 2023, which was addressed through standard procedures including a letter notification. While the building itself is a relatively modern structure for the area, having been built in 1979 and classified as a flats and duplex building, the ongoing parking enforcement activity suggests a recurring challenge in the immediate vicinity. The documented parking violations represent the most significant pattern of incidents associated with this address, as evidenced by the relatively high frequency of enforcement actions required to address these issues over the past year and a half.

Risk rating

How 4157 26Th 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
43rdpercentile

Out of 1879 buildings in this neighborhood, 1071 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
