Frequently Asked Questions

Your ADU Questions Answered

Everything you need to know about building an ADU in Los Angeles, from costs and timelines to permits and rental income.

Getting Started

What is an ADU?

An Accessory Dwelling Unit (ADU) is a secondary housing unit on a single-family residential lot. ADUs can be detached structures in your backyard, converted garages, or additions to your existing home. They include a kitchen, bathroom, and living space, making them fully functional independent living units.

How do I know if my property qualifies for an ADU?

Most single-family residential properties in Los Angeles qualify for an ADU. We offer a free feasibility assessment where we review your property's zoning, lot size, setbacks, and existing structures to determine what type and size of ADU you can build. Contact us to schedule your free assessment.

What's the first step to building an ADU?

The first step is to schedule a free consultation with our team. We'll assess your property, discuss your goals and budget, review zoning requirements, and provide you with a preliminary feasibility report and cost estimate. This initial consultation helps you understand what's possible on your property.

Do I need to hire an architect separately?

No, we provide full design-build services. Our team includes experienced designers who will create plans for your ADU. We handle everything from initial design concepts through final construction, so you only need to work with one company throughout the entire process.

Costs & Financing

How much does it cost to build an ADU?

ADU costs vary based on type and size. Junior ADUs (JADUs) typically cost $70K-$95K, garage conversions range from $90K-$120K, and detached ADUs cost $130K-$175K. These estimates include design, permits, construction, and all necessary systems. We provide detailed cost breakdowns during your consultation.

What financing options are available for ADU construction?

Common financing options include home equity loans, home equity lines of credit (HELOC), cash-out refinancing, construction loans, and personal loans. Some homeowners also use retirement savings or partner with family members. We can connect you with lenders who specialize in ADU financing.

Are there any grants or incentives for building ADUs?

California offers various ADU incentives, including streamlined permitting, reduced fees, and potential property tax exemptions. Some local jurisdictions offer additional incentives or pre-approved plans. We stay current on all available programs and can help you take advantage of any applicable incentives.

When do I need to pay for the ADU construction?

Payment is typically structured in phases: a deposit when you sign the contract, payments at key construction milestones (foundation, framing, rough-in, finishes), and a final payment upon completion. We provide a detailed payment schedule in your contract so you know exactly when payments are due.

Timeline & Process

How long does it take to build an ADU?

Total timeline from start to finish typically ranges from 6-12 months. This includes design and permitting (2-4 months) and construction (3-6 months). Junior ADUs are fastest at 4-6 months total, garage conversions take 3-6 months, and detached ADUs take 4-8 months. We provide a detailed timeline during your consultation.

What is the ADU construction process?

Our process includes five main phases: 1) Feasibility assessment and design consultation, 2) Final design and permit applications, 3) Permit approval and pre-construction planning, 4) Construction and inspections, 5) Final walkthrough and certificate of occupancy. We manage every step and keep you informed throughout.

How long does the permit process take?

Permit review in Los Angeles typically takes 60-120 days, depending on project complexity and current city workload. We handle all permit applications, respond to plan check comments, and coordinate with the city to expedite the process. Pre-approved ADU plans can sometimes reduce permit timelines.

Can I live in my home during ADU construction?

Yes, for detached ADUs and garage conversions, you can typically remain in your home during construction. There may be temporary disruptions for utility connections or when work affects shared systems. For JADUs that involve converting part of your existing home, you may need temporary alternative arrangements for certain phases.

Design & Features

Can I customize my ADU design?

Yes, we offer both pre-designed ADU plans and fully custom designs. Pre-designed plans are more cost-effective and faster to permit, while custom designs allow you to create exactly what you envision. We work with you to balance your design preferences with your budget and timeline goals.

What utilities does an ADU need?

ADUs require connections to water, sewer, electricity, and gas (if applicable). We handle all utility connections as part of our service, including coordinating with utility companies, trenching for new lines, and installing meters if required. All utility work is included in our project estimates.

Can my ADU have a second story?

Yes, two-story ADUs are allowed in Los Angeles with a maximum height of 25 feet. Two-story designs maximize living space on smaller lots and can include features like upstairs bedrooms and downstairs living areas. Height restrictions may vary based on your specific zoning district.

What finishes and features can I include in my ADU?

ADUs can include any features you'd find in a regular home: full kitchens with appliances, bathrooms with showers or tubs, hardwood or tile flooring, central heating and cooling, washer/dryer hookups, and outdoor patios or decks. We help you select finishes that fit your budget and rental market expectations.

Permits & Regulations

What permits do I need to build an ADU?

You'll need a building permit from the Los Angeles Department of Building and Safety (LADBS). This covers architectural plans, structural engineering, electrical, plumbing, and mechanical systems. We handle all permit applications, plan submissions, and coordination with the city as part of our service.

Do I need HOA approval to build an ADU?

California law prohibits HOAs from banning ADUs, but they may impose reasonable design restrictions. We recommend reviewing your HOA's CC&Rs early in the process. We can work with your HOA to ensure your ADU design meets their requirements while maximizing your property's potential.

Will building an ADU increase my property taxes?

Building an ADU will increase your property's assessed value, which may result in higher property taxes. However, California offers a property tax exclusion for ADUs under certain conditions. The rental income from your ADU typically far exceeds any property tax increase, making it a worthwhile investment.

Can I sell my ADU separately from my main house?

No, ADUs cannot be sold separately from the primary residence. They must remain on the same lot as the main house and cannot be subdivided. However, you can sell your entire property (including both the main house and ADU), which typically increases the property's market value significantly.

Rental & Use

How much rental income can I expect from my ADU?

ADU rental rates in Los Angeles typically range from $1,800-$3,800 per month, depending on size, location, and amenities. Junior ADUs rent for $1,800-$2,200, garage conversions for $2,000-$2,500, and detached ADUs for $2,200-$3,800. We can provide market analysis for your specific area.

Can I use my ADU for family members instead of renting it?

Many homeowners build ADUs for aging parents, adult children, or other family members. This provides independent living space while keeping family close. ADUs are perfect for multi-generational living arrangements, offering privacy and independence for everyone.

Can I use my ADU as a home office or studio?

Yes, ADUs can be used for home offices, art studios, music rooms, gyms, or any other personal use. While they're designed as complete living units, there's no requirement to rent them out. Many homeowners use their ADUs for personal purposes and have the option to rent later if needed.

Do I need to live on the property if I rent out my ADU?

California law previously required owner-occupancy for ADUs, but this requirement has been suspended until 2025. Currently, you can rent out your ADU without living on the property. However, regulations may change, so we recommend staying informed about current requirements.
