10-Step Process
Welcome to Our Streamlined ADU Building Process
From Idea to Move-In, Perpetual Homes is with You Every Step of the Way
Our proven 10-Step Process guides California homeowners from concept to move-in, with expert guidance at every stage. Whether you're building for family, rental income, or a lifestyle upgrade, we're here for you every step of the way.
1
Complimentary Virtual Assessment
We help you assess your existing property, then guide you in selecting the model that best fits your needs, site conditions, and goals. With over 30 thoughtful designs to choose from, we’ll help you start smart. We can provide a ballpark estimate within minutes.
2
Feasibility Analysis
For a flat $250 due diligence fee, we provide a comprehensive evaluation of your property and local regulations. From overlay zones and site work estimates for foundations and utilities to jurisdictional fees and easement considerations, we give you the clarity you need to move forward with confidence.
3
Site Visit
Our team visits in person to verify measurements, assess delivery and construction access, and walk through your ideas on-site. This is where your project begins to feel real.
4
Design & Permitting
We manage most permit applications and prepare architectural, civil engineering, and site plans to ensure full compliance with local and state regulations. Please note that clients are responsible for covering the associated plan fees.
5
Transparent Project Estimate
You receive a clear, line-by-line estimate that reflects your site’s condition and chosen upgrades.
6
Personalize Your Design
Choose finishes, layout tweaks, energy-saving features, and smart upgrades that align with your vision—whether you’re building for aging-in-place, rental, or guest use.
7
Factory-built Construction
Your ADU is built off-site in a controlled facility for maximum speed, precision, and quality. No weather delays, fewer inspections, and faster results.
8
On-site Prep in Parallel
While your ADU is being built, we prep the site: laying the foundation, trenching for utilities, and coordinating inspections. It’s a parallel process that saves time. Unlike many other ADU companies, there is zero general contractor markup (which can cost up to 30% more).
9
Deliver, Connect, & Finalize
Your fully built ADU arrives and is carefully put into place, seamlessly connected onsite. From delivery and installation to final finishes, utility hookups, and inspection, the average on-site process takes just 2–4 months. You're nearly home.
10
Move In With Confidence
We hand you the keys to your finished, fully inspected home. We’ll walk you through every feature—and celebrate your new beginning.
Perpetual Homes supports homeowners throughout Northern California and beyond with guided ADU design, permitting, construction, and move-in planning for customizable prefab backyard homes.
