What will my ADU really cost?
Build a complete planning budget by separating the dwelling itself from site work, professional services and a reserve. Catalog ranges are starting points, not bids.
Make your next ADU decision
Work through the questions that affect feasibility, comfort and cost before committing to construction.
All practical guides
Will an ADU fit on my property?
Lot area is one starting point. The usable building space also depends on access, existing structures, setbacks, recorded restrictions and utilities.
Design an ADU around everyday life
A successful small home makes daily routines comfortable. Plan the entrance, kitchen, bathroom, laundry and storage around the future occupant.
From your first ADU idea to a useful partner proposal
A written project brief helps a partner understand what you want and makes competing proposals easier to compare.
Can your basement become an ADU?
Start with the existing building. A separate kitchen does not by itself establish a legal dwelling.
Garage ADU conversion checklist
An existing roof can save work, but a garage was not necessarily designed as living space.
Plan an ADU for multigenerational living
Design around the person who will use the home now and how those needs may change.
Compare ADU builder bids fairly
A low headline price can hide unfinished scope. Compare the same work, allowances and responsibilities.
Prefab or site-built ADU?
Compare the installed, permitted project rather than the factory price against a contractor’s complete bid.
ADU utilities, inspections and handoff
Resolve service capacity early and collect the documents you will need after construction.
