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 1987
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 property at 4050-4054 17th Street in Corona Heights is an 8-unit, 3-story multi-family residential building owned by William & Kathleen McDonagh and was constructed in 1987. The building has undergone several significant maintenance and repair projects over the years, with recent work including a $17,000 reroofing project in 2016 and substantial repairs in 2016 addressing dry rot damage, exterior painting, and garage sheetrock repairs costing $18,000. Historical records show recurring issues with both dry rot and exterior maintenance, with a 2001 repair project for $1,500 replacing stucco and siding due to similar concerns.

The building experienced multiple code violations in February 2001, with violations related to fire safety, security, and building maintenance, including issues with fire extinguishers, weatherproofing, self-closing doors, lighting, and building permits. These violations were all officially abated by October 23, 2001, during a routine housing inspection. A cluster of complaints in 2009-2010 indicated various maintenance issues, including rodent infestation and electrical problems, though all were resolved through proper channels. More recently, the property has faced external challenges, as evidenced by multiple 311 calls in late 2024 regarding garbage, debris, and encampments in the vicinity. While there was a tenant buyout of $35,000 for one tenant at 4040 17th Street in January 2022, records indicate no injuries from the single documented fire incident involving the property, which occurred in a structure outside the main building in 1992 and was determined to be unintentional.

Risk rating

How 4050-4054 17Th 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
14thpercentile

Out of 348 buildings in this neighborhood, 299 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.

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.

Property class

The assessor's property-class code, which correlates with building type and the violation rates the model expects. This code is grouped with other less-common classes.
