Perpetual Homes is leading the way as Californians turn to ADUs amid housing crisis

November 18, 2024

   Experience affordable multigenerational living at its finest. Perpetual Homes builds single-family, duplex homes and accessory dwelling units. In response to the housing challenges faced by Californians due to low inventory, high prices and increasing interest rates, ADUs have emerged as a creative solution. Leading the way in providing sustainable turnkey backyard homes is Danville-based Perpetual Homes, a company committed to enhancing property values and addressing the demand for housing solutions.

   Since 2019, Perpetual Homes' experienced team have been actively involved in delivering eco-friendly and sustainable ADUs throughout the Bay Area. From initial site inspection and permits to construction, utility connections, site cleanup, and final inspections, the company manages every aspect of the project.

   Founder and President Katherine Anderson's vision revolves around factory-built, award-winning designs using sustainable materials. Recognizing the housing shortage issue, Anderson emphasizes that by some estimates, California is 3.5 million housing units short, contributing to the overall national deficit of around 6 million homes. More households have been formed than homes built over the past decade.

   California accounts for about half of the national shortage of homes. California's new ADU laws aim to address the housing deficit by allowing the construction of units up to 1,000 to 1,200 square feet, reducing setbacks to 4 feet, waiving certain permitting requirements, eliminating owner-occupancy restrictions, reduced development fees for units under 750 square feet, and implementing a streamlined 60-day review and approval process. Multi-family properties are also eligible for up to two detached ADUs. Under Senate Bill 9, homeowners are allowed to build up to four additional units on their existing lots.

They can add an additional single-family home to their property and even split the lot. SB 9 allows fourplexes in areas that previously only allowed one home and allows homeowners to divide their property into two lots. In California, 1 out of 5 residential building permits are for ADUs.
   Perpetual Homes offers a very desirable solution: Prefab 1,200 square-foot ADUs at a mid-project cost of $300,000, providing an affordable alternative to the high prices of newly built townhomes in the region, which can exceed $900,000. These ADUs not only contribute to the vision of affordable living in the Bay Area but also enable families to access top-rated schools. Perpetual Homes also offers entry-level ADU starting-home sizes - the 500 square-foot Piedmont plan - which provides for multigenerational living, starting in the mid-$200,000s *all-in." Our latest plan offers duplex living.

   The company manages all aspects of the ADU project, from budget creation and contracts to plans, permitting. prefab home manufacturing, on-site construction coordination, utility connections, and turkey move-in services. The construction process is designed to minimize disruption to residents of the primary dwelling unit.

   Perpetual Homes emphasizes the long-term rental potential, attracting responsible tenants who contribute positively to local communities. Some homeowners choose to move into their ADUs and rent out their primary houses, enhancing their financial security and overall quality of life.

   The prefabrication aspect of Perpetual Homes ADUs is a key advantage, allowing for construction in an enclosed facility at a lower cost compared to traditional methods.

This not only results in quicker construction times but also minimizes the noise and dust associated with on-site construction.
