What to expect,
week by week.

We plan an ADU project in Longmont at 3–6 months from signed contract to move-in. Here is what happens in each phase, and what each one depends on.

The Addwell timeline

1

Property assessment & design selection

1–2 weeks

    This is the "kitchen table" phase. No commitment until you sign.

    2

    Permitting

    4–8 weeks

      Longmont's ADU permit process is well-established. Typical review is 4–6 weeks; 8 weeks is conservative.

      3

      Construction

      8–14 weeks

        Panelized construction significantly compresses the framing phase. You get weekly photo updates throughout.

        4

        Closeout & handoff

        1 week
