Rent & eviction protection

Is 170-174 Dolores 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.

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

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 3-unit residential building at 170-174 Dolores Street, built in 1915, has undergone significant renovations and improvements over the past several years. Most notably, in 2019, the property received substantial safety upgrades including the installation of a comprehensive fire sprinkler system with 91 sprinklers throughout, a new fire alarm system with sprinkler monitoring, and various plumbing and electrical improvements totaling over $30,000. The building's units underwent extensive remodeling in 2018, with updates to water, sewer, and gas lines, as well as electrical systems, including new bathrooms, kitchens, and laundry facilities in all three units. A major roof deck and light well infill project was also approved, along with bathroom and closet reconfigurations across multiple floors.

The property has experienced some maintenance and safety issues in the past, particularly during 2017 when multiple violations were recorded, including problems with heating, electrical outlets, stairs, windows, and a rodent infestation. However, all these violations were officially abated by July 2017. Two tenant buyouts were conducted in June 2018, with compensation amounts ranging from approximately $28,000 to $30,000 per tenant. Recent complaints have primarily been related to building maintenance and urban issues in the surrounding area, with several 311 calls in 2024 regarding encampments, tree maintenance, and pavement defects near the property. The building's fire safety systems were briefly investigated in 2020 but were determined to have no merit. The property is currently owned by Cypress Family Trust and has been maintained as a multi-family residential building throughout its history.

Risk rating

How 170-174 Dolores 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
61stpercentile

Out of 799 buildings in this neighborhood, 312 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.

Neighborhood (ZIP code)

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

Building age

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

Building size

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