ADU design-build · NorwalkADUs in Norwalk
Single-story homes, attached garages and steady rental demand: Norwalk suits garage conversions as much as compact detached ADUs.
What applies to your lot
Building an ADU in Norwalk
Who approves your ADU
City of Norwalk: ADUs follow Section 17.04.210 of the Norwalk Municipal Code, and construction follows Title 15. State law applies everywhere: a decision within 60 days of a complete application, no public hearing, and at least 800 sq ft with 4 ft side and rear setbacks.
A clear city guide
Norwalk publishes an ADU guide for homeowners: types of units, setbacks and construction rules. We use it with you at the visit.
No owner-occupancy rule for ADUs
The owner does not have to live on site for an ADU. For a junior ADU, the owner must live in the house or the JADU.
Sprinklers only if the house has them
An ADU needs fire sprinklers only when the main house has them. Most homes do not, which keeps costs down.

Can I convert my attached garage?
Often yes. An existing legal structure can become an ADU, and the city cannot require replacement parking for the converted garage.
