Permitting depends on your jurisdiction. Cities like Saratoga and Sunnyvale can approve plans in as little as 30–45 days, while LA County averages 2–3 months. We manage all permitting for you and maintain close relationships with many agencies to keep things moving efficiently.

Our warranty covers structural components, waterproofing, insulation, and core systems. Appliances and fixtures are covered under their manufacturer warranties.

Triple-pane windows, steel framing, and precision factory construction create homes that are quieter, sturdier, and more energy-efficient. The result: a structure that feels like a high-end home, not a “prefab.” Every unit is built to last decades — with minimal maintenance and maximum comfort.

ADUs have become one of California’s most effective ways to add flexible living space and long-term property value. Remote work has increased demand for guest suites, home offices, and studios. Strong rental markets make ADUs attractive income-producing assets, and adding high-quality, permitted square footage reliably boosts property value. Recent state legislation has also made ADUs significantly easier to approve and build, and cities are encouraging small-scale infill housing to address ongoing housing shortages. For many homeowners, an ADU is the most economical way to gain more space while building wealth at the same time.

Yes — especially in California’s high-demand markets. ADUs offer multiple layers of value: they provide flexible living space for remote work or multi-generational housing, add high-quality permitted square footage that increases property value, and perform well as long-term rentals in markets where demand remains strong. California’s ADU-friendly laws also make development more predictable and accessible than ever. LiveLarge can guide you through design, permitting, and cost analysis so you can maximize the return on your investment.

ADUs increase property value in several ways. They create immediate income potential through long-term, mid-term, or—where allowed—short-term rentals. They also add fully permitted square footage, which appraisers value highly. Beyond financial return, ADUs offer lifestyle flexibility for offices, guest suites, multi-generational living, or aging-in-place, all of which broaden a home’s appeal. Homes with ADUs typically attract more buyers, sell faster, and command higher prices. Prefab units like ours also shorten construction timelines and reduce uncertainty, improving both ROI and the overall homeowner experience.

AB 68

Landlords can add two units to a single-family lot:

• One attached or detached ADU up to 1,200 sq ft
• One JADU up to 500 sq ft

AB 434

All cities must provide pre-approved ADU plans online by January 1, 2025.

These plans may include architect-designed options, with small fees for access or modifications.

SB 477

Consolidates state ADU and JADU laws into a single code chapter and requires cities to post processing data and reports online.

Single-family homeowners can build:

• One ADU up to 1,200 sq ft
• One JADU up to 500 sq ft

Both are allowed under current statewide standards, making ADUs more accessible.

JADUs no longer need their own private bathroom. They may share a bathroom with the primary residence as long as it’s accessible.

Yes. While ADUs are typically secondary structures, they can serve as the primary residence on a vacant lot with the correct permits.

LiveLarge also offers main-home configurations of our larger units. These include additional architectural details and code requirements while maintaining our fast timelines and high construction standards.

Typically yes, based on city regulations. Many homeowners rent both structures independently.

We can help you navigate your specific jurisdiction’s rules.

ADUs come in several forms:

• Detached cottages (what LiveLarge builds)
• Garage conversions
• Basement or attic conversions
• Attached additions
• Junior ADUs (JADUs)
• Tiny homes or movable units

LiveLarge specializes exclusively in detached prefab ADUs, as they deliver the best combination of quality, value, and streamlined construction.

LiveLarge delivers higher-quality homes by combining advanced materials with a fully integrated professional team.

Our units are built with steel framing for strength, fire resistance, and long-term durability; triple-pane windows for quietness, comfort, and energy efficiency; and double insulation with low-VOC interior materials for a healthier indoor environment. Every floor plan is optimized for natural daylight, and each unit undergoes rigorous HCD inspections throughout the factory build. On site, installation is completed by licensed crews trained specifically on LiveLarge units.

We also have professional architects, structural engineers, and civil engineers on staff, ensuring that design, engineering, and installation are coordinated by a single team of experts from start to finish. The result is a healthier, quieter, longer-lasting home built with precision at every stage.

Homeowners are responsible for landscaping repairs. Crane operations follow strict safety measures, but due to the size of equipment and nature of access, some yard impact is possible. Most homeowners handle small repairs after installation.

LiveLarge units are built under the California Residential Code (CRC) and fully inspected by California HCD. With steel framing and high-quality materials, they are designed to last as long or longer than a traditional stick-built home.

A construction loan is a short-term loan used to finance the cost of building or renovating a home. For ADUs, a construction loan can cover materials, labor, and related expenses. These loans typically convert into a permanent mortgage once the project is completed. The approval process may require documentation such as project plans, contractor agreements, and detailed budgets. Construction loans can be a flexible option for homeowners who plan to build a custom ADU or need financing tied to specific project milestones.

Cash-out refinancing allows homeowners to replace their existing mortgage with a new, larger one and receive the difference in cash. This cash can then be used to pay for ADU construction. This option can be appealing when interest rates are favorable, and homeowners want to consolidate financing within a single mortgage. However, it’s important to consider closing costs, interest rate changes, and long-term financial goals before choosing cash-out refinancing for ADU construction.

Several government programs and incentives may support ADU construction, depending on your location. These can include low-interest loans, grants, or tax credits aimed at increasing housing availability. Some states and municipalities offer additional incentives for creating affordable rental units or improving energy efficiency. Exploring available local programs can help reduce the overall cost of building an ADU.

An FHA 203(k) loan is a federal program that bundles the cost of purchasing or refinancing a home with the cost of renovating or improving it. For ADUs, this loan can cover construction expenses, including structural modifications, energy efficiency improvements, or adding new living spaces. The 203(k) loan provides a streamlined way to finance both the property and the ADU project, making it an attractive option for homeowners seeking flexible financing with lower down payments.

Choosing the right loan depends on factors such as your financial situation, project scope, and long-term goals. Evaluate the available loan types—home equity loans, HELOCs, construction loans, cash-out refinancing, and government-backed loans—to determine which best fits your needs. Consider aspects like interest rates, repayment terms, and the timeline for accessing funds. Consulting with financial experts or lenders can help you make a well-informed decision tailored to your ADU project.

Yes. Working with a financial advisor or mortgage broker can provide valuable insight into your loan options and help you navigate the complexities of financing an ADU. These professionals can guide you through interest rates, repayment terms, and eligibility requirements. Their expertise ensures you choose the most suitable financing solution based on your financial situation and project goals.

Yes. LiveLarge works with a curated list of preferred lenders who specialize in ADU and home-equity financing. Our partners include:

• CrossCountry Mortgage
• Hong Hu
• Additional vetted lenders for HELOCs and home equity loans

We can introduce you directly to lenders who understand ADU-specific financing requirements.

Your Proposition 13 protections on your main home remain unchanged.

Only the new ADU receives a new assessment. Your base home assessment stays protected.

The ADU will be assessed separately based on its construction value and size.

Your main home’s assessment does not change.

This means your overall property tax increase is modest, especially compared to buying a second property.
