About Nestadu

Nestadu: Full-Service ADU Design, Permitting, and Construction

Nestadu is a comprehensive ADU builder and ADU contractor that handles every stage of the process — from design and permitting through to final construction. As a dedicated accessory dwelling unit builder, they serve a wide range of budgets, property types, and design preferences, offering both site-built custom ADUs and prefabricated units delivered fully assembled to the backyard.

Their team brings extensive construction experience, having built hundreds of homes and delivered billions in project value. Whether a homeowner is looking for a backyard cottage builder, a granny flat builder, or a fully custom detached unit, Nestadu offers a streamlined, hassle-free process designed to make ADU development as straightforward as possible.

Custom Site-Built and Prefab ADU Options

Nestadu offers two primary paths for homeowners: custom site-built ADUs and prefab ADUs. Custom ADUs are built directly on the property to meet exact specifications, offering complete flexibility in design, materials, and layout. Prefab ADUs are pre-designed, factory-built units delivered fully assembled — a faster and often more cost-effective solution.

For site-built ADUs, pricing starts from $400 per square foot, with timelines of approximately 8 to 10 months. Homeowners can choose from nine signature architectural styles or work with Nestadu's design team to create a fully custom layout. Available styles range from timeless and traditional to sleek and minimalist, including:

  1. Timeless elegance with modern sophistication
  2. Rustic charm with modern openness
  3. Mediterranean stucco-inspired designs
  4. Sleek minimalist and contemporary styles
  5. Handcrafted, nature-inspired interiors
  6. Vintage elegance fused with contemporary flair

For prefab ADUs, Nestadu offers several pre-designed floor plans under their Nest product line. These units are elegantly constructed and delivered fully assembled, making them an excellent option for those seeking an efficient backyard cottage or in-law suite solution. Available prefab models include:

  1. Nest (Studio, 1 Bath, 200 sq. ft.) — Starting from $115,000. A versatile and compact unit ideal for additional living or office space, with optional bathroom and customizable finishes.
  2. Nest Studio (Studio, 1 Bath, 330 sq. ft.) — From $225,000 or $1,500/month. Features a full bath and modern kitchen in a luminous, comfortable layout.
  3. Nest One (1 Bed, 1 Bath, 497 sq. ft.) — From $263,000 or $1,950/month. A self-contained unit with a full kitchen, bedroom, and bath, featuring a distinctive sloped roof that invites natural light.
  4. Nest Two (2 Bed, 1 Bath, 638 sq. ft.) — From $317,000 or $2,800/month. A spacious two-bedroom unit with full kitchen, laundry amenities, and ample bath — ideal for families, guests, or rental income.

ADU Financing Options

Nestadu also provides guidance on financing options to help homeowners fund their ADU project. Through trusted partners, they can help explore solutions tailored to individual financial situations. Common financing paths include:

  1. Home Equity Line of Credit (HELOC) or Home Equity Loan — Leveraging existing home equity with flexible or fixed-rate options.
  2. Cash-Out Refinance — Refinancing an existing mortgage to access additional funds, often at lower interest rates.
  3. Construction Loans — Ideal for those with limited home equity, based on the projected post-improvement value of the property.
  4. Personal Loans or Lines of Credit — An option for those without savings or home equity, though typically at higher interest rates.
  5. Hard Money Loans — Suitable for real estate investors or multifamily property owners seeking short-term, flexible financing.
  6. Government Programs and Grants — Including California-specific programs such as CalHome and LEAP grants, as well as nationwide HUD programs.
  7. Alternative Financing — Emerging options such as peer-to-peer lending and equity investment platforms.

As a full-service detached ADU builder and accessory dwelling unit builder, Nestadu combines quality craftsmanship, design flexibility, and transparent pricing to deliver ADU solutions that add lasting value to any property.

"I expected prefab to look generic, but Nestadus finish work made it feel custom. The layout works well, the lighting is great, and its quiet inside. The schedule was clear, and set day was handled professionally."
