Rent & eviction protection

Is 704 Castro 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 1900

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.

15+ years since occupancy
Built 1900
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

704 Castro Street is a two-unit, two-story multi-family residential building constructed in 1900, currently owned by Aoyagi Shota & Lee Jung Eun. The property has undergone several significant renovations over the years, with the most substantial being a proposed expansion and full interior remodel as of February 2019, which aims to transform the upper unit from a 2-bedroom/1-bath to a 3-bedroom/2.5-bath configuration, and to remodel both units' kitchens and bathrooms. This project, documented in the planning records, would also include vertical and horizontal additions to the building's front and rear sections. Prior improvements include a complete kitchen and bath upgrade in 2015 (including plumbing and electrical work), front stair repairs in 2015, and various renovations in the 1990s and 1980s including kitchen and bathroom updates, new furnace installation, and termite repairs.

The building's maintenance and minor infractions record shows regular upkeep of the property, though there have been recurrent issues with illegal parking in the vicinity, with multiple citations issued between 2020 and 2023. The property has experienced occasional maintenance issues requiring attention, such as defaced signs (2023), illegal postings (2021), and hazardous materials on the street (2021), all of which were resolved. The 2019 proposed expansion project is the most significant recent development, marking a substantial investment in improving the property's residential units, though as of the latest available data, this permit is still listed as "filed." The building's historical records show consistent maintenance and upgrades over the decades, with no tenant buyouts recorded at this address.

Risk rating

How 704 Castro 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
73rdpercentile

Out of 1278 buildings in this neighborhood, 345 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 location

Precise location is a proxy for neighborhood-level risk — some SF blocks have systematically higher DBI activity.

Building age

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

Building permits, owner's portfolio

Permits pulled across all of this owner's buildings over 7 years.
