Why Hire an ADU Contractor Instead of a General Remodeler

As a licensed ADU contractor building in Los Angeles since 2009, we know local zoning thoroughly. In addition, our full-time trades handle each phase directly under one unified agreement.

General remodelers often juggle varied residential projects and rely heavily on transient subcontractors. Instead, our dedicated crews build accessory dwelling units every single week across Southern California. Because we specialize exclusively in ADUs, we anticipate LADBS structural plan check requirements early. Furthermore, our established supply chains prevent material delays and protect your construction budget. Finally, we maintain complete accountability from breaking ground to final utility connections.

Construction Process

Our Step-by-Step Construction Process

We guide your build through four disciplined stages to ensure predictable timelines and superior quality. Also, our unified contract eliminates miscommunication between architects and field crews.

01

Site Prep & Foundation

First, our survey crew stakes out property setbacks and verifies underground utility locations. Then, our excavation team trenches sewer laterals and pours a steel-reinforced concrete foundation.

02

Framing & Envelope

Next, our carpenters erect structural wall framing and install engineered roof trusses. After framing inspections, we install weather barriers, exterior sheathing, and Title 24 windows.

03

Mechanical Rough-Ins

Meanwhile, our licensed electricians and plumbers run all wiring, water pipes, and drain lines. In addition, our technicians set ductless mini-split heat pumps for optimal climate control.

04

Interior & Exterior Finishes

Finally, our finish carpenters hang drywall, lay premium flooring, and mount custom kitchen cabinets. Once city officials complete final inspections, we deliver your keys and certificate of occupancy.

Common Questions

ADU Contractor: Frequently Asked Questions

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

What does an ADU contractor do during a project?
A full-service ADU contractor manages every stage of your accessory dwelling unit project from concept to keys. First, our team conducts a thorough property assessment to examine lot boundaries, zoning overlays, and soil conditions. Next, our designers draft custom architectural plans and coordinate structural engineering calculations. Then, we submit documentation to LADBS and clear all municipal plan check corrections. Finally, our construction crew performs site excavation, utility trenching, framing, and interior finish work. That way, you work with one accountable partner throughout the entire build.
How do I verify the credentials of an ADU contractor in Los Angeles?
First, verify that the builder holds an active Class B General Building Contractor license through the CSLB website. Always confirm current workers compensation coverage and general liability insurance before signing any contract. In addition, examine past project portfolios to inspect construction quality on completed Southern California units. You should also request recent references from local property owners who built similar backyard structures. Furthermore, demand a transparent fixed-price contract that defines payment milestones clearly. Reputable builders never ask for substantial upfront payments before pulling city permits.
Why should I hire a specialized ADU contractor instead of a general remodeler?
Dedicated accessory dwelling unit specialists focus exclusively on California detached and attached backyard construction. Instead, a general remodeler divides attention between kitchen updates, roof repairs, and minor additions. Because ADUs function as independent residential homes, they demand complex utility connections and Title 24 compliance. Our specialized experience helps us clear city inspections swiftly and prevent expensive revision cycles. Therefore, an expert ADU contractor delivers faster build times and protects your overall investment. Local trade crews handle backyard cottages every working day with proven efficiency.
How much does hiring an ADU contractor cost in Los Angeles?
Total investment depends on unit size, structural style, and specific lot conditions. For example, garage conversions typically start at $95,000 for standard two-car layouts. Standalone custom detached units generally range from $150,000 for studios to $240,000 for two-bedroom homes. Furthermore, complex two-story builds or steep hillside sites often start at $300,000. As an honest ADU contractor, we provide transparent fixed-price proposals before construction begins. This upfront agreement covers architectural design, structural engineering, city fees, and all physical building trades. Consequently, you avoid unpredictable billings while keeping your overall financing secure.
How long does an ADU contractor take to complete construction?
Most turnkey builds in Los Angeles County require nine to fourteen months from design to final inspection. First, our architectural design and engineering phase takes roughly four to eight weeks. Next, city plan check review through local building departments requires ten to sixteen weeks on average. Once officials approve permits, our crews complete physical construction within five to eight months. Meanwhile, garage conversions move faster, often reaching substantial completion in four to six months. In addition, our full-time project managers track weekly milestones to prevent unnecessary schedule delays.
What California laws and zoning rules apply to ADU construction?
State legislation like AB 68 and SB 9 created substantial rights for California single-family homeowners. First, state regulations permit detached units up to 1,200 square feet with four-foot side and rear setbacks. In addition, the California HCD ADU Handbook confirms exemptions from replacement parking near public transit. Municipalities cannot impose minimum lot sizes or require costly discretionary design reviews. Therefore, an informed ADU contractor navigates these statutory protections to maximize your allowable building area. Our team handles local ordinances across Los Angeles to safeguard your project approvals.
Do I need separate utility meters for my accessory dwelling unit?
Utility connection requirements depend on whether you intend to rent the cottage to independent tenants. For instance, dedicated electrical subpanels allow tenants to pay their own electric utility bills directly. However, installing separate municipal water or gas meters often incurs steep utility connection fees. Instead, many homeowners install all-electric heat pumps and sub-meter power consumption very economically. During initial site planning, our experienced ADU contractor evaluates your main panel capacity thoroughly. Then, our engineering team designs the most practical utility routes to minimize yard disruption.
What type of contract should I sign with an ADU contractor?
You should always insist on a detailed fixed-price contract with clear milestone payment schedules. Unlike cost-plus agreements, fixed-price contracts protect property owners from unexpected labor or material surges. In addition, California law strictly caps down payments at $1,000 or 10 percent, whichever is less. Subsequent disbursements should align directly with verified municipal inspection sign-offs. For example, payments release after foundation pours, framing completion, rough trade inspections, and final occupancy. Finally, ensure the written agreement includes a comprehensive one-year workmanship and structural warranty. Our clear contracts eliminate financial ambiguity from day one.
Can an ADU contractor build on hillside or sloped lots in LA?
Yes, building on sloped terrain requires specialized structural engineering and foundation drilling experience. First, our geotechnical engineers conduct soils testing to establish slope stability and bedrock depth. Next, we design reinforced retaining walls and deep concrete friction piles to anchor the structure securely. Furthermore, our excavation teams establish safe staging zones to protect existing residential foundations. While hillside construction involves higher engineering costs, it unlocks stunning views and valuable rental income. As an experienced ADU contractor, we have delivered complex hillside accessory units across Los Angeles. Today, we evaluate hillside feasibility during our initial property assessment.
