After decades on a downward trajectory, metro-area mobile home parks show signs of expanding to meet what park owners say is increased demand for the low-cost manufactured housing.
No new Twin Cities mobile home communities have sprung up since the 1990s, many have closed, and Metropolitan Council data show no mobile park expansions between 2000 and 2018.
But in the past two years, mobile parks in Rosemount, St. Francis and Ham Lake have added or plan to add 108 manufactured home sites in all.
"The need is absolutely dire at this point in time," said Al Schrader, whose park, Woodhaven in St. Francis, added 55 lots in 2018.

Industry professionals say factories are back-ordered for the low-slung homes, in part because they are drawing a new generation of residents. Young professionals and downsizing seniors are looking for smaller, less costly homes with minimal maintenance, they said.
"We have a lot of people who want to live here and we just don't have room for them," said Sherry Saxon, operations manager at Flamingo Terrace in Ham Lake, where Continental Communities is in the early stages of planning a 25-site expansion.
Housing advocates say that mobile homes — the industry prefers "manufactured housing" — can help solve the affordable housing crisis, offering low-income families lots of space for the dollar and a chance at homeownership.
"Manufactured housing is often an overlooked affordable housing asset," said Freya Thamman, a Met Council planning analyst. "The cost … is so small compared with site-built homes."
