About Our Team

Complete ADU for Sale Solutions for California Homeowners

ADU Build LA delivers fully installed ADU for sale packages across Los Angeles County since 2009. Today, our experienced craftspeople provide fixed pricing and complete municipal approvals for every client.

Many internet kit sellers deliver unpermitted prefab shells directly onto residential driveways. However, unassembled kits leave property owners stranded with complex utility trenching and local inspections. Instead, our dedicated building company delivers complete site-built accessory homes ready for immediate occupancy. Our specialized in-house crews manage foundation engineering, Title 24 energy compliance, and sewer connections. Therefore, buyers avoid expensive project surprises and receive fully permitted living spaces.

Purchase to Completion

Our Four-Step Delivery and Installation Process

We simplify buying an accessory dwelling through four transparent development phases. Then, our field supervisors oversee municipal site approvals and utility connections.

01

Site Feasibility & Permitting

First, our engineers evaluate lot setbacks, utility depths, and soil conditions. Next, we submit engineered architectural plans to municipal building departments for expedited approvals.

02

Foundation & Trenching

Our crews excavate utility lines and pour an engineered concrete foundation slab. After concrete cures, technicians install subterranean plumbing runs and electrical conduits.

03

Framing & Utility Rough-Ins

Carpenters construct structural framing and install high-performance dual-pane windows. Then, licensed trades install heat pump HVAC systems, electrical circuits, and water distribution pipes.

04

Finishes & Final Sign-Off

Finally, our finish team installs custom cabinetry, quartz countertops, and durable flooring. Once city inspectors complete final inspections, we hand over your ready-to-use keys.

Common Questions

ADU for Sale: Frequently Asked Questions

What Los Angeles homeowners ask most before starting an ADU project.

What is included when I purchase an ADU for sale package?
When you select a turnkey ADU for sale package, our team covers every construction requirement. First, our in-house designers create permit-ready architectural and structural engineering plans. Next, we manage municipal plan check submissions directly through your local building department. Licensed construction crews excavate foundations and trench dedicated sewer, water, and power lines. In addition, every package includes high-efficiency heat pump HVAC systems and designer interior finishes. Finally, city inspectors issue a legal certificate of occupancy upon final walkthrough. Therefore, buyers avoid coordinating separate designers, engineers, and subcontractors on their own.
How do site-built turnkey ADUs compare to uninstalled prefab kits?
Unassembled catalog kits often look inexpensive online but create massive hidden costs for property owners. Many kit vendors ship wall panels without foundation work, utility trenching, or permits. Instead, buying an ADU for sale through our company includes comprehensive site installation. Because Los Angeles lots require custom utility tie-ins, site-built methods adapt easily to property slopes. Furthermore, site-built construction ensures strict adherence to California Title 24 energy mandates. Our single-contract model protects your budget from unexpected third-party assembly charges. Thus, homeowners receive a durable home that appraises higher with local lenders.
How much does a turnkey installed ADU cost in Los Angeles?
Turnkey pricing in Los Angeles County ranges from $130,000 to over $240,000 depending on unit dimensions. For instance, installed prefab modular units start from $130,000 on accessible residential parcels. Meanwhile, custom site-built studio packages start from $150,000 with complete foundation work included. Spacious one-bedroom and two-bedroom residences typically range between $185,000 and $240,000. Our fixed-price contracts cover architectural design, municipal permitting, utility trenching, and finish construction. Therefore, buyers never experience surprise billing spikes during ongoing site operations. We confirm exact package numbers during your initial on-site property evaluation.
How long does the purchase, permitting, and installation timeline take?
Most turnkey accessory projects require eight to twelve months from purchase agreement to move-in day. First, our architectural team prepares custom site engineering documents within four to six weeks. Next, we submit plans to the Los Angeles Department of Building and Safety for plan check review. LADBS plan check reviews usually take ten to sixteen weeks depending on department workload. After permit issuance, our crews complete grading, foundation pouring, and utility hookups within two months. Then, interior framing, mechanical installations, and finish carpentry take another three to four months. Finally, city inspectors sign off the completed structure for immediate residential occupancy.
What lot requirements must my property meet to install an ADU?
California building statutes permit accessory dwellings on virtually all single-family and multifamily residential parcels. Under the California HCD ADU Handbook, homeowners can build detached structures up to 1,200 square feet. In addition, state standards require minimum four-foot side and rear boundary setbacks. Your backyard must also accommodate clear access routes for excavation equipment and building materials. When exploring a detached ADU for sale, our team evaluates electrical panel capacities and sewer depths. Consequently, we resolve potential lot constraints before you commit to final purchase contracts.
Can I customize the floor plan and finish selections for my unit?
Yes, every package allows tailored architectural modifications to suit your family lifestyle or rental goals. First, you can select from multiple studio, one-bedroom, and two-bedroom layout options. Next, our designers adjust window placements and patio door locations to maximize natural light. Buyers choose from curated selections of kitchen cabinets, quartz countertops, plumbing hardware, and flooring. Furthermore, we can incorporate accessible zero-step entries and walk-in showers for aging family members. Overall, our packages blend standardized cost efficiencies with personalized design flexibility.
Does California state law allow me to rent my newly installed ADU?
Yes, California housing statutes grant property owners the legal right to lease accessory structures. Under California AB 976, state law permanently removed owner-occupancy rules for standard ADUs. Because rental demand in Los Angeles remains high, new backyard homes generate reliable monthly rental returns. Local one-bedroom units frequently rent for $2,200 to $3,200 every month. In addition, rental income can offset your construction financing payments from day one. Therefore, purchasing an accessory home is an effective strategy to expand real estate wealth.
How do property taxes change after purchasing and installing an ADU?
Adding an accessory dwelling prompts only a blended property tax reassessment under California Proposition 13. The county tax assessor assesses only the market value of the newly added improvements. Your primary home retains its protected, historical tax base without reassessment. For example, investing $150,000 into an ADU for sale package adds roughly $1,500 to $1,800 in yearly taxes. Meanwhile, monthly rental revenues or multigenerational housing savings dramatically surpass this modest expense. Thus, property owners build substantial equity while preserving favorable long-term tax protections.
