Accessory & Secondary Dwelling Units

Accessory / Secondary Dwelling Units (ADU / SDU) are a fast growing part of our residential market. 
  • An Accessory Dwelling Unit (ADU) or Secondary Dwelling Unit (SDU) is a unit built on a property that already has a main dwelling unit.
  • Typically built as detached structures but can also be created in the basement or on the 2nd floor of an existing home.
  • Municipalities have recently amended their zoning by-laws to allow for most residential zones to have up to 2 or 3 dwelling units per property.
  • Nauta Home Desgins provides blueprints for these units with guarantee of permit.

Our ADU/SDU Process:

This form provides us with all of your project information so that we can hit the ground running

An onsite consultation is almost always necessary. This helps us to determine the feasibility and options for the project.

Based on the scope, complexity, and scale of your project, including unlimited revisions, project specifications, and guarantee of permit

Our team returns to measure and take photos of the existing property or space

After we have drafted your existing space onto our system we will create concepts and a first draft for you to review

Your designer will communicate with you on each revision, making changes until you are satisfied with the final design

The drawings are completed, thoroughly reviewed, and readied for submission to your local Building Department
