familiar feature of residential development in Los Angeles.<\/p>\n\n\n\n<p>Detached cottages, garage conversions, and small secondary residences allow homeowners to introduce additional living space without replacing their primary houses.<\/p>\n\n\n\n<p>For years, the most recognizable arrangement involved a single detached ADU positioned behind the main residence.<\/p>\n\n\n\n<p>California&#8217;s upcoming regulations introduce a more complex possibility.<\/p>\n\n\n\n<p>Under AB 956, qualifying properties with an existing or proposed single-family dwelling can accommodate up to two newly constructed detached ADUs through the applicable streamlined approval process.<\/p>\n\n\n\n<p>This could mean three independent residential buildings occupying one property: the primary house and two smaller homes.<\/p>\n\n\n\n<p>However, expanded legal opportunities do not automatically translate into sufficient physical space.<\/p>\n\n\n\n<p>A successful project must account for building placement, access, privacy, natural light, landscaping, and the infrastructure needed to support additional households.<\/p>\n\n\n\n<h2

class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>Two properties with identical square footage can offer very different development possibilities.<\/p>\n\n\n\n<p>A relatively wide lot may have enough room to accommodate two compact detached buildings side by side. A long, narrow parcel might require a completely different arrangement.<\/p>\n\n\n\n<p>Existing structures also influence the available building area.<\/p>\n\n\n\n<p>A detached garage, swimming pool, mature trees, or utility easement may occupy parts of the property that initially appear suitable for construction.<\/p>\n\n\n\n<p>Even seemingly minor site characteristics can significantly affect the design.<\/p>\n\n\n\n<p>For example, a narrow side yard may create challenges for construction access. Changes in elevation can increase the complexity of foundations and drainage systems.<\/p>\n\n\n\n<p>These constraints make early site analysis especially important.<\/p>\n\n\n\n<p>California&#8217;s updated law expands what may be permitted, but local building and safety requirements still apply.<\/p>\n\n\n\n<p>Homeowners looking for a detailed explanation of the legislative changes can explore Ataman Studio&#8217;s guide to&nbsp;<a href=\"https:\/\/www.atamanstudio.com\/resources\/california-adu-laws-2027-two-detached-adus\/\" target=\"_blank\" rel=\"noopener\">California ADU laws for 2027<\/a>, including how AB 956 affects the possibility of building two detached units on one lot.<\/p>\n\n\n\n<figure class=\"wp-block-image\"><img decoding=\"async\" src=\"https:\/\/la-future.com\/wp-content\/uploads\/sites\/54\/2026\/11\/3br-adu-light-1.webp\" alt=\"Modern ADU in Los Angeles\" \/><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Three_Architectural_Approaches_to_Two_Backyard_Homes\"><\/span>Three Architectural Approaches to Two Backyard Homes<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>The arrangement of two detached ADUs can significantly influence how the entire property functions.<\/p>\n\n\n\n<p>While no single configuration is suitable for every site, several planning approaches illustrate the possibilities.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Side-by-Side_Backyard_Homes\"><\/span>Side-by-Side Backyard Homes<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>On a wider lot, two smaller units may be positioned next to each other toward the rear of the property.<\/p>\n\n\n\n<p>This arrangement can simplify the overall organization of the site and create a recognizable relationship between the buildings.<\/p>\n\n\n\n<p>Each residence may have its own entrance and a small private patio or landscaped area.<\/p>\n\n\n\n<p>However, designers must consider the distance between structures, window placement, and how residents move through shared parts of the property.<\/p>\n\n\n\n<p>The buildings should feel like independent homes rather than two structures competing for the same limited backyard.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Staggered_Building_Placement\"><\/span>Staggered Building Placement<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>For deeper or irregularly shaped properties, staggered placement may offer greater flexibility.<\/p>\n\n\n\n<p>Instead of aligning the two units, one building can be positioned farther back or offset from the other.<\/p>\n\n\n\n<p>This can improve privacy by preventing windows from directly facing neighboring living spaces.<\/p>\n\n\n\n<p>It may also create opportunities for separate outdoor areas and more varied landscaping.<\/p>\n\n\n\n<p>The challenge is to maintain comfortable circulation while ensuring that both homes receive adequate daylight and ventilation.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Courtyard-Oriented_Design\"><\/span>Courtyard-Oriented Design<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>A third possibility involves arranging the buildings around a landscaped courtyard.<\/p>\n\n\n\n<p>Rather than treating the remaining outdoor space as an afterthought, the courtyard becomes a central architectural feature.<\/p>\n\n\n\n<p>It can provide a visual connection between the residences while allowing each household to maintain independent interior spaces.<\/p>\n\n\n\n<p>Thoughtful landscaping, covered walkways, and carefully positioned entrances can help establish boundaries between shared and private areas.<\/p>\n\n\n\n<p>This approach may be particularly appealing for multigenerational households.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Privacy_Becomes_an_Architectural_Priority\"><\/span>Privacy Becomes an Architectural Priority<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>Adding one backyard home changes the relationship between a primary residence and its outdoor space.<\/p>\n\n\n\n<p>Adding two makes privacy significantly more complicated.<\/p>\n\n\n\n<p>The design must account for views between three residences, potential noise, and the location of entrances and outdoor gathering areas.<\/p>\n\n\n\n<p>Bedrooms should not unnecessarily overlook neighboring patios.
