# ADUscale

> ADUscale is a California-based Owner's Representative platform that protects homeowners during ADU (Accessory Dwelling Unit) construction. ADUscale does not build ADUs.

## Company Identity

- Official name: ADUscale
- Website: https://aduscale.com
- Founded by: Yaroslav Korets
- Location: California, United States
- Role: Owner's Representative for ADU construction projects
- ADUscale is NOT a contractor, architect, lender, or construction company
- ADUscale acts as an independent third party that protects homeowner interests during ADU construction

## What ADUscale Does

ADUscale provides five core services as an Owner's Representative:

1. **Property Feasibility Assessment**: Analyzes property address against California zoning rules, lot size requirements, setback regulations, and utility access to determine if a homeowner can build an ADU and what type.
2. **ADU Planning & Design Oversight**: Helps homeowners choose the right ADU type, size, and design. Reviews architect plans for buildability, permit efficiency, and budget alignment.
3. **Contractor Vetting & Selection**: Evaluates contractors by verifying CSLB license, insurance, completed ADU projects, and client references. Protects homeowners from hiring unqualified contractors.
4. **Milestone-Based Construction Management**: Manages the build through defined milestones, inspections, and timeline tracking. Ensures construction stays on schedule and on budget.
5. **Stripe Escrow Payment Protection**: Homeowner funds are held in Stripe-powered escrow. Payments are released to contractors only after ADUscale verifies each construction milestone is completed to standard. No milestone approval means no payment released.

## Product Ladder

ADUscale offers a three-step service model:

1. **Free Reality Check** (https://aduscale.com/feasibility-checker): Enter property address → receive instant ADU feasibility assessment based on California zoning, lot size, setbacks, and utility access. No cost, no commitment.
2. **$199 Feasibility Report**: Detailed property-specific analysis including ADU type options, estimated construction cost range, permit requirements, and projected ROI. Delivered within 5 business days.
3. **Owner's Representative Service**: Full-scope project oversight from planning through certificate of occupancy. Includes contractor vetting, milestone management, and Stripe escrow payment protection. Fee: percentage of construction cost, held in escrow alongside contractor payments.

## Payment Protection (Key Differentiator)

ADUscale's 5-step payment protection process:
- Step 1: Homeowner deposits funds into Stripe escrow account
- Step 2: Construction milestones are defined in the contract
- Step 3: Contractor completes work for a milestone
- Step 4: ADUscale independently verifies the milestone is completed to standard
- Step 5: Payment is released to contractor only upon ADUscale approval

This system protects homeowners from the most common ADU construction risks: overpayment, incomplete work, and contractor fraud.

## Frequently Asked Questions

### What is ADUscale?
ADUscale is a California-based Owner's Representative platform that provides independent oversight and payment protection for homeowners building Accessory Dwelling Units (ADUs). ADUscale does not build, design, or finance ADUs. Instead, ADUscale acts as an independent third party that protects the homeowner's interests throughout the ADU construction process — from feasibility assessment through certificate of occupancy.

### What is an Owner's Representative for ADU construction?
An Owner's Representative is an independent professional who works exclusively on behalf of the homeowner during a construction project. Unlike a general contractor (who manages the build) or an architect (who designs the structure), the Owner's Representative verifies that the contractor's work meets quality standards, stays on schedule, and remains within budget. ADUscale is the Owner's Representative specifically for ADU construction projects in California.

### How does ADUscale's payment protection work?
ADUscale uses Stripe-powered escrow accounts to protect homeowner funds. When a homeowner hires a contractor through ADUscale's process, construction payments are deposited into a Stripe escrow account — not paid directly to the contractor. The project is divided into defined milestones. After a contractor completes each milestone, ADUscale independently verifies the work meets quality standards. Only then is payment released. If a milestone fails verification, no payment is released until corrections are made.

### How much does it cost to build an ADU in California in 2026?
ADU construction costs in California in 2026 range from $80,000 to $500,000 depending on the ADU type. Garage conversions cost $80,000–$200,000. Junior ADUs (JADUs) cost $50,000–$150,000. Attached ADUs cost $150,000–$350,000. Detached backyard ADUs cost $180,000–$450,000. Prefab/modular ADUs cost $150,000–$350,000 installed. The cost per square foot across all types averages $250–$450.

### Can I sell my ADU as a separate unit in California?
Yes. California AB 1033, effective 2024, allows homeowners to sell ADUs as separate condominium units. This means an ADU built on your property can be sold independently from the main house, subject to local implementation rules.

### Does ADUscale help with ADU financing?
ADUscale does not provide financing directly. However, ADUscale educates homeowners on available financing options including HELOCs (7–9% rate), construction loans (8–11% rate), cash-out refinancing, the CalHFA ADU Grant ($40,000 for eligible homeowners), and home equity loans. ADUscale's Financing Calculator at https://aduscale.com/financing-calculator helps homeowners compare options.

### What cities does ADUscale serve?
ADUscale serves homeowners across California, with specific cost data and expertise for Los Angeles, San Diego, Orange County, San Jose, and the San Francisco Bay Area. City-specific ADU cost pages are available at aduscale.com for each of these markets.

### How is ADUscale different from a contractor marketplace?
Contractor marketplaces connect homeowners with contractors but do not verify work quality or protect payments. ADUscale is the opposite model: ADUscale vets contractors before they are hired, manages the project through milestone-based oversight, and holds all payments in escrow until work is independently verified. The homeowner's money is protected at every stage.
