Complete ADU Construction Across Los Angeles
Skalwest Construction builds detached ADUs, attached additions, garage conversion ADUs, and other accessory dwelling unit projects throughout Los Angeles. We coordinate the work from site preparation and foundations through framing, utilities, exterior assemblies, interior construction, inspections, and final property completion.
Los Angeles properties vary dramatically. A project may involve a deep Valley lot with a detached garage, a compact urban property with narrow side-yard access, a hillside home with retaining walls, an alley-served site, or a finished backyard containing pools, patios, landscape, and other improvements. Skalwest reviews the actual property conditions alongside the plans so the construction strategy reflects the real site.
New ADU construction can require demolition, excavation, foundations, utility trenching, plumbing connections, electrical service, drainage, grading, waterproofing, and other site preparation before framing begins. Utility distance, access, soil conditions, grade, and existing hardscape can all affect how this early work is completed.
ADU construction can include foundations, framing, structural connections, roofing, windows, waterproofing, insulation, exterior finishes, plumbing, electrical systems, HVAC, drywall, cabinetry, countertops, kitchens, bathrooms, tile, flooring, appliances, lighting, hardware, and finish carpentry. As an ADU contractor and builder, Skalwest coordinates these stages as one complete residential build.
Material deliveries, demolition, utility interruptions, temporary protection, equipment, debris removal, dust, noise, and subcontractor access all affect the surrounding property. We organize construction around both the new ADU and the portions of the site that homeowners continue using during the build.
Two ADUs with nearly identical floor plans can require very different construction scopes. Foundation conditions, grade, retaining walls, utility distance, access, existing improvements, demolition, and the distance between the street and building area can change the project even when the finished square footage is similar.
Different Types of ADUs We Build in Los Angeles
Accessory dwelling units can be created through several fundamentally different construction approaches. The appropriate option depends on the property, existing residence, available yard, garage location, utilities, privacy, access, terrain, and the amount of new structural work required.
Detached ADU construction can include excavation, foundations, framing, roofing, windows, exterior finishes, plumbing, electrical systems, HVAC, insulation, drywall, cabinetry, kitchens, bathrooms, flooring, lighting, appliances, and site improvements. Starting with new construction allows the major building systems to be coordinated together from the beginning.
An attached ADU can involve new foundations, framing, structural openings, roof tie-ins, plumbing, electrical connections, HVAC, insulation, waterproofing, exterior finishes, and interior separation. Because the addition becomes physically connected to the existing house, conditions inside the primary residence can influence the construction scope.
Garage conversions can require foundation assessment, structural upgrades, insulation, new windows and doors, plumbing, electrical work, HVAC, kitchens, bathrooms, waterproofing, flooring, and exterior modifications. Skalwest evaluates the existing garage so the conversion scope reflects the real condition of the structure instead of assuming every original element should remain.
Los Angeles includes many hillside and canyon properties where the construction strategy can be substantially different from a level lot. Depending on the site, an ADU may involve excavation, retaining conditions, engineered foundations, drainage, waterproofing, exterior stairs, or restricted access. These conditions should be coordinated with the architecture and engineering early.
A strong ADU design should also translate cleanly into construction. Structural spans, roof geometry, plumbing walls, window locations, mechanical equipment, cabinetry, waterproofing details, utility paths, and exterior materials all affect how efficiently approved plans can become a finished residence.
From Los Angeles ADU Plans to Complete Construction
Construction works best when the approved drawings, engineering, real property conditions, utilities, subcontractor scopes, material selections, and inspection sequence are coordinated before they become urgent in the field. Skalwest approaches those elements as parts of one connected residential project.
Before major construction begins, Skalwest can review the project in relation to the actual site. This can identify demolition, temporary protection, utility routes, access limitations, structural conditions, material decisions, long-lead items, staging needs, and other issues that affect how the approved ADU will be constructed.
Depending on the project, this stage can include demolition, excavation, trenching, grading, foundations, retaining work, framing, structural connections, roofing, windows, flashing, waterproofing, and exterior wall systems. These elements establish the geometry and durability of the residence before interior systems and finishes are installed.
Rough plumbing, electrical wiring, HVAC, ventilation, insulation, and other required building systems are installed in coordination with the structure. Inspection sequencing matters because many components need to remain visible until the appropriate City review is completed.
The finish phase can include drywall, cabinetry, countertops, tile, flooring, plumbing fixtures, appliances, lighting, painting, hardware, doors, finish carpentry, exterior paving, drainage, landscape restoration, corrections, and final inspections. We carry the build through the point where both the ADU and surrounding property are ready for use.
An ADU is smaller than most primary homes but contains nearly the same essential systems. Plumbing, electrical work, HVAC, cabinetry, appliances, windows, insulation, waterproofing, lighting, storage, and structure therefore require precise coordination because there is less space to absorb dimensional conflicts during construction.
Skalwest can help coordinate the transition from planning into field construction, including project scope, permit drawings, engineering, existing-property conditions, utilities, and practical construction requirements. As an ADU contractor and builder, we look at the plans not only as approval documents, but as instructions that eventually have to work on the real Los Angeles property.
ADU construction cost in Los Angeles depends on building size, project type, foundation conditions, structural complexity, utility distance, kitchens and bathrooms, cabinetry and finish level, garage condition, demolition, construction access, grading, retaining work, pools or landscape conflicts, and restoration of surrounding site improvements.
LADBS maintains an approved Standard Plan Program intended to simplify part of the permitting process for qualifying ADUs. The plans are pre-reviewed for applicable building, residential, and green-code requirements, but LADBS still evaluates site-specific zoning and foundation conditions. Skalwest can coordinate construction around either an approved standard plan or a custom ADU design.
Building a Los Angeles ADU as a Complete Residence
A successful ADU should do more than add square footage and pass final inspection. Building-envelope performance, climate control, kitchens, bathrooms, storage, lighting, acoustics, privacy, outdoor circulation, and finish quality all contribute to how the residence performs over time.
Water management, roofing, flashing, windows, insulation, air sealing, exterior finishes, drainage, and properly coordinated penetrations create the protective shell of the ADU. These details are less visible than cabinetry and tile but remain fundamental to long-term residential performance.
Kitchens and bathrooms bring several trades into limited space. Cabinet dimensions, appliances, plumbing fixtures, electrical outlets, lighting, waterproofing, tile, countertops, and finish carpentry should be coordinated before installation rather than independently resolved in the field.
A detached or attached ADU can use private entries, acoustic construction, carefully oriented windows, landscape screening, efficient HVAC, and dedicated outdoor areas to create a comfortable residential identity while remaining connected to the primary property.
Flooring, cabinetry, hardware, tile, lighting, paint, fixtures, doors, trim, countertops, exterior finishes, and landscape transitions can be selected around the intended quality of the project. Skalwest treats the ADU as permanent residential construction rather than temporary backyard space.
The space immediately outside a detached ADU can complete the project as effectively as the interior finishes. A planted courtyard, shaded path, private patio, garden wall, landscape screen, or exterior lighting can establish a sense of arrival while connecting the residence naturally to the larger property.
Skalwest combines the coordination of an ADU contractor with the physical construction experience of an ADU builder. We carry projects through site work, foundations, framing, utilities, building systems, interiors, inspections, finishes, and final site completion with the goal of delivering one complete residential project.
