ADU Feasibility Report

Find out if your property can take an ADU — before you spend on plans.

An ADU can add rental income, house family, and build real value into your property. But plans, permits, and design work cost serious money — and none of it makes sense until you know what your lot can legally take. Our ADU Feasibility Report answers that first, in writing, for one flat fee.

The Questions This Report Answers

Can this lot legally take an ADU?
We check your zoning and lot against current California ADU rules and your city’s code.
What type fits?
Detached ADU, garage conversion, attached ADU, or a JADU inside your home — and why.
What size?
The maximum unit your lot, setbacks, and coverage limits actually allow.
What will it roughly cost?
A planning cost range for the recommended option, based on real California project costs.
What could it rent for?
A rent estimate range based on comparable units near your property.
What’s the permit path?
The steps, requirements, and fees your city will put in front of you.

What’s Included in Your Report

  • Lot & zoning review — ADU eligibility for your specific parcel, including size limits, setbacks, and lot coverage.
  • Recommended ADU type + maximum size — the option that fits your lot and your goals.
  • Build-cost range — a planning range for the recommended build, not a guess pulled from the internet.
  • Rent estimate range — what a finished unit like yours could rent for in your area.
  • Utility & sewer considerations — the water, sewer, and electrical questions that most often change the budget.
  • Recommended next steps — exactly what to do next if the numbers work, and what to watch out for if they don’t.

Who prepares your report: ADU Cities is part of Mars Construction Industries Corp — a licensed California contractor, CSLB #1138550 (A – General Engineering, B – General Building). We’re building exceptional ADU’S in every city, with garage conversions, attached ADU’S, and detached backyard homes handled in-house by our own crews throughout California.

The ADU Feasibility Report is a planning document based on public records, the information you provide, and the rules in effect when it’s prepared. It is not a permit, a city approval, a formal appraisal, or a construction bid. Cost and rent figures are planning ranges; a fixed written quote follows a site visit.
