How building codes and zoning laws slow down advancements in sustainable architecture. <\/em><\/p>\n By: Emily Downey<\/p>\n If you\u2019re like me, you may have seen some news recently about how engineers, architects, and builders are utilizing new (and old) building techniques to respond to the challenges presented by a changing climate. Be it fire resilient design in California[1]<\/a>, integration of green technology such as solar and water reclamation[2]<\/a>, or the proliferation of tiny homes[3]<\/a>, many are turning to smarter and more energy efficient methods when it comes to building their dream home.<\/p>\n But innovation often comes with legal challenges. One of the most poignant examples has been the difficulty faced by architects in California having to adapt fire resistant designs to existing building codes.[4]<\/a> While some states are taking measures to attempt to ease the way for green design and face popular support, progress can be slow.[5]<\/a> This is partially because building codes and zoning laws are highly localized, meaning that broad measures often do not address more granular issues like City ordinances and neighborhood covenants and restrictions.[6]<\/a> To see how these challenges can be overcome, we can look to lessons learned from an oddly named pioneer of the green home movement: the earthship.<\/p>\n What is an earthship? <\/strong><\/p>\n Earthships are the invention of New Mexico architect Michael Reynolds, who built the first earthship in the 1970s as a way to solve problems with both rubbish accumulation and affordable housing.[7]<\/a> He did this by doing something novel and strange\u2014building a house out of garbage.[8]<\/a> While a garbage home doesn\u2019t initially sound appealing, Reynolds\u2019 design soon amassed a following, especially in areas around Taos, New Mexico.[9]<\/a> Reynolds pioneered a building technique using earth, tires, and \u201cbricks\u201d made of discarded cans to create hyper-modern edifices that are virtually indestructible and come with a myriad of green perks.[10]<\/a> The homes allow occupants to live entirely or almost entirely off grid, are super-efficient to heat and cool, and come with novel water reclamation systems in place.[11]<\/a> The homes can also be affordable, as they emphasize the use of local and often discarded materials and provide for onsite food production[12]<\/a><\/p>\n <\/p>\n So why aren\u2019t there more earthships? <\/strong><\/p>\n Earthships are difficult to legally build in the United States. Earthship advocates have had to deal with an uphill legal battle from the beginning.[13]<\/a> In New Mexico, Michael Reynolds spearheaded the Sustainable Development Testing Site Act, which passed in 2007 and allows counties to designate specific rural areas for the testing and development of sustainable technologies and concepts in a state which historically used large tracts of land as a nuclear testing ground.[14]<\/a> In Reynolds\u2019 words, the Act allows him to \u201ctranscend\u201d the laws already in place to carve out a place for earthships and other new building methods.[15]<\/a><\/p>\n Additionally, each earthship is a unique structure. Some are built like whimsical sandcastles with jewel-like recycled glass windows, while others blend into the landscape. But neighborhoods in the United States have long favored \u201ccookie cutter\u201d houses, and the abundance of Homeowners\u2019 Associations (\u201cHOAs\u201d) and covenanted neighborhoods disincentivize the building of structures that don\u2019t fit the mold.[16]<\/a> To get around this obstacle, homeowners have elected to build in rural areas that typically lack covenants and restrictions.[17]<\/a><\/p>\n Other issues include the difficulty in insuring and financing these unique homes.[18]<\/a> Mortgage lenders rely on comparable listings (\u201ccomps\u201d) to accurately assess the value of a home, and earthships often don\u2019t reliably compare to other homes in a given area.[19]<\/a> This makes it nearly impossible to get a conventional mortgage on an earthship, so prospective builders and buyers must either seek out alternative forms of financing or pay in cash on hand.[20]<\/a> This makes these homes\u2014meant to be affordable\u2014into expensive enterprises that are also a gamble on the resale market.[21]<\/a> An earthship is a home for life by necessity.<\/p>\n How do earthships get built? <\/strong><\/p>\n There are two ways\u2014adapt to local building codes or do like Reynolds and find a way to circumvent them. Currently, you can obtain a permit to build an earthship in New Mexico, Pennsylvania, Wyoming, Nevada, Colorado, Florida, and Virginia.[22]<\/a> But this still requires navigating a tricky legal landscape. For example, Virginia passed Green Development Zone legislation in 2017 allowing towns, cities and counties to establish green development zones by ordinance, and providing for regulatory flexibility in those zones.[23]<\/a> However, outside of these zones, localities have no flexibility outside of the Virginia Uniform Statewide Building Code (\u201cUSBC\u201d), and few localities have gone forward to designate Green Development Zones.[24]<\/a> Additionally, permits for things like onsite solar panels can rack up costs. Prospective earthship builders may have to do all of the permitting work themselves, and must buy the panels outright if they wish to avoid dealing with utility companies.[25]<\/a><\/p>\n The takeaway lesson?<\/strong><\/p>\n Innovative architecture can be costly and time consuming, and it can require a lot of creativity and legal maneuvering. But these designs show us that incorporating eco-friendly building practices can be done. \u201cSelf-sustaining power and warmth and electricity through solar panels, roof water capture and reuse, this is the future,\u201d says Kim Shanahan, former head of the Santa Fe Area Homebuilders Association and expert in the field of green homebuilding.[26]<\/a> In Shanahan\u2019s words, it is \u201cnot necessarily tires in walls, but all the other principles that Mike Reynolds has taught us about what a house can and should be.\u201d[27]<\/a> And even when law is slow to catch up, a little flexibility can go a long way for the advancement of sustainable design.<\/p>\n Image link:<\/p>\n https:\/\/pixabay.com\/vectors\/ufo-spaceship-alien-sci-fi-8759621\/<\/a><\/p>\n [1]<\/a> Rob Enderle, Building Back a Better Los Angeles With Fire-Resistant <\/em>Homes, TechNewsWorld (Jan. 20, 2025, 5:00 AM), https:\/\/www.technewsworld.com\/story\/building-back-a-better-los-angeles-with-fire-resistant-homes-179541.html.<\/p>\n [2]<\/a>See, e.g.<\/em>, Rachel Estabrook, Want to recycle your own water at home?
