Sonoma County builder Orrin Thiessen walked up a narrow, unfinished staircase and with pride began describing the 550-square-foot granny units being built as part of his Green Valley Village housing development in downtown Graton.
The small dwellings now are little more than an array of 2-inch by 6-inch wood framing studs and plywood floors and walls. The compact design of each includes a kitchen, living area, bathroom, bedroom and laundry closet.
“It’s got everything you need,” Thiessen said, standing in the living room, holding his arms out.
The construction of these slight apartments in Sonoma County is considered a key part of helping to ease the housing affordability crunch. But building them, he said, simply isn’t financially viable, especially in rural parts of the county where smaller sewer districts charge heftier connection fees and rates.
Local cities and towns have been rushing to reduce impact fees and restrictions to encourage construction of these so-called granny units, prompted by changes in state laws and the devastating 2017 wildfires. For example, Santa Rosa sharply reduced its impact fees for these smaller housing units, also known as secondary homes, and are starting to see significant response from builders and homeowners.
In some cases, other municipalities are charging 50 percent or even 33 percent of the regular hookup fee for sewer connections. Homeowners and builders say each incremental fee reduction helps bring down the overall cost of construction of the smaller homes.
