How old they are.
Half the apartment parcels in 91105 Pasadena were built in 1937 or earlier. 100 of 106, about 94%, went up in 1978 or before.
Across the 255 ZIP codes on this site that share is 89%, so 91105 Pasadena has a larger share of older buildings than the average. Older buildings tend to carry the questions a buyer will ask about, like plumbing, electrical, the roof and whether the building needs a seismic retrofit.
Rent control in 91105 Pasadena.
1 of the 106 parcels in 91105 sit inside the City of Los Angeles by the city's zoning map. 1 of those were built in 1978 or earlier, and those are the buildings most likely to fall under the Los Angeles Rent Stabilization Ordinance.
That figure is worked out from the build year and the city line. It is not the Housing Department's own list, so check a single building on the LAHD lookup before you rely on it. Buildings in the city that the ordinance does not cover are often still under the state cap in AB 1482.
The other 105 parcels in this ZIP are outside the city or have no zoning record here, so the city ordinance does not reach them. Unincorporated county areas have their own rent stabilization rules.
How long owners hold.
The median Prop 13 base year for apartment parcels in 91105 Pasadena is 2005. A base year resets when a building sells, so an old one usually means the same owner or the same family has held it a long time.
30 parcels, 28%, still carry a base year of 1995 or earlier. The figure for all 255 ZIP codes here is 28%, so owners in 91105 Pasadena have held about as long as the average.
Long-held buildings often pay property tax on a value set decades ago. When they sell, the new owner is taxed on the price, which is part of why rents and expenses on these buildings need a close look before anyone sets a price.
How often buildings sell.
By last recorded transfer, 8 apartment parcels in 91105 Pasadena changed hands in 2022, 6 in 2023 and 10 in 2024.
That is 9.4% of the parcels here, against 7.3% across all 255 ZIP codes, so buildings here turned over more often than the average.
A building that sold twice in those years shows up once, in its later year, and a transfer is not always a sale at market. A move into a trust or between family members is recorded too.
