Residential Feasibility Studies for ADUs, Additions and Custom Homes

A feasibility study is the cheapest money you will spend on a project. It answers four questions before design fees start: can this be built, roughly what will it cost, what approvals are required, and how long will it take. Custom homes, additions and ADUs all start the same way here: a short study that says whether the custom home or unit you have in mind fits the lot.

What this covers

  • Lot and zoning analysis
  • Utility and sewer capacity review
  • Setback, height and coverage testing
  • Preliminary cost range
  • Approval path and schedule

Questions people ask before hiring

What is included in a residential feasibility study?

Zoning and overlay analysis, setback and height testing, a utility and sewer capacity check, a test-fit massing, an approximate cost range and a written approval path with a realistic schedule.

What if the study says the project does not work?

Then you saved the cost of a full design. In most cases we can also identify a smaller or reconfigured version of the project that does work.
