What actually drives ADU cost.
Cost is the biggest question for most homeowners - so we won't hide from it. Here's an honest look at what shapes a CityPaks project, without invented prices.
Selected CityPaks configuration
The Pak and layout you choose sets the base scope of your project.
Site conditions
Slope, access, soil and existing structures all affect what's involved.
Foundation requirements
A slab, crawlspace or other foundation depends on your site and engineering.
Utilities
Connecting power, water, gas and sewer - or alternatives - varies by property.
Trenching & electrical
Distance to existing utilities drives trenching and electrical work.
Sewer / septic
Sewer connection or alternative systems depend on your location and jurisdiction.
Permitting
Permit fees and requirements differ by city and county across the Bay Area.
Jurisdiction requirements
Local rules, impact fees and conditions affect total project cost.
We don't publish invented prices.
Every Bay Area property is different, and a real number requires a real review. If approved starting prices or investment ranges are supplied, this page is designed so they can be added easily.
The most accurate next step is a property-fit consultation - we'll talk through your site, your goals and a realistic investment picture.
Let's discuss what fits your property.
No endless forms or automated sales pressure. Just a direct, thoughtful conversation with Lori about your yard, your goals, and which CityPaks ADU actually works.
