Placentia will get 139 new townhomes in the southeastern corner of the city.

Landsea Homes has begun construction on the “Hudson” community at 443 S. Van Buren Street, an old auto yard between the Santa Fe railroad tracks and Atwood Channel, just south of Orangethorpe Avenue.

Sales will begin later this year but no pricing has been announced.

The project called “Hudson” will be gated with 63 traditional row townhomes and 76 back-to-back townhomes from 775 to 1,638 square feet of space with one to three bedrooms and up to three bathrooms.

Elsewhere in Placentia, the 54-home Camila project by Shea Homes — a little more than a mile away — sold out in the past year.

Landsea recently began selling the 65-townhome Nolin community and began construction on the 489-home Narra Hills community in Fontana.

Orange County builders have been slow to catch up with the demand for homes.

In the 12 months ended in February, 2,735 new homes were sold in the county, according to DQNews. That was down 8% from the previous year and 37% below the 2015-2019 annual pace.

In the past seven years, the median selling price of an Orange County residence is up 70% to $985,000.
