Custom Backyard House Construction In Los Angeles
We build fully permitted standalone backyard homes on solid foundations across Los Angeles. In addition, our licensed crews manage architecture, city permits, and ground-up construction.
About Our Team
Los Angeles Backyard House Builders On Real Foundations
Our team has built every custom backyard house across Los Angeles since 2009 with enduring structural integrity. In fact, we construct code-compliant tiny homes on permanent concrete foundations rather than temporary chassis trailers.
Many homeowners explore portable tiny homes on wheels as quick backyard additions. However, Los Angeles municipal codes require permanent foundations and Title 24 energy compliance. Unpermitted trailer homes risk heavy city code enforcement fines and forced removals. Instead, our dedicated trades build legal detached accessory dwelling units from 300 to 500 square feet. We connect permanent sewer laterals, water lines, and dedicated electrical subpanels directly. Consequently, your permitted living space adds verified equity and safe rental income to your property.

Construction Process
Our Four-Step Ground-Up Building Process
Our unified design-build method guides your project through four clear engineering phases. Therefore, you enjoy predictable schedules and verified inspections from foundation through final occupancy.
Site Prep & Foundation
First, our survey crew stakes property lines and verifies soil bearing capacity. Next, we excavate utility trenches and pour a reinforced monolithic concrete foundation slab on grade.
Framing & Weatherproofing
Then, our framing carpenters erect structural exterior walls, ceiling joists, and roof rafters. Furthermore, we install weather-resistant building wrap, high-performance roof underlayment, and Title 24 dual-pane windows.
Mechanical Rough-Ins & Utilities
Meanwhile, licensed electricians, plumbers, and HVAC technicians install underground sewer laterals, water supplies, and ductless heat pumps. After rough-in installation, city building inspectors verify all mechanical trades on site.
Interior Finishes & Handover
Finally, our finish team installs drywall, custom cabinetry, quartz countertops, full tile showers, and luxury vinyl flooring. Once city officials complete final sign-offs, we hand you your certificate of occupancy.
