More than an add-on.
A complete residence.

At DALLAN Construction, an Accessory Dwelling Unit is a fully functional, residential-grade living space designed with purpose and built with precision.

An ADU is a secondary home located on the same lot as a primary residence — completely independent, with its own kitchen, bathroom, living area, sleeping space, and separate entrance.

When properly designed and permitted, an ADU adds flexibility, long-term value, and opportunity to your property.

Four approaches. One standard of quality.

01

Detached ADU

A standalone structure built separately from the primary home. Ideal for rental income, multigenerational living, or private guest accommodations.

02

Attached ADU

An addition connected to the existing home but designed with a separate entrance and fully independent living features.

03

Garage Conversion

Transforming an existing garage into a fully livable dwelling while maintaining structural integrity and meeting residential code requirements.

04

Basement ADU

A finished basement converted into an independent living space with proper egress, utilities, and sound separation.

Eight phases. Zero shortcuts.

Phase 01

Feasibility & Zoning

Lot size, setbacks, height limits, parking, and utility access evaluated before a single dollar is committed.

Phase 02

Budget & Financing

We define a clear investment range — cash, home equity, construction loans, or renovation financing.

Phase 03

Design & Planning

Efficient floor plans, structural drawings, mechanical systems, and finish selections — maximizing function without sacrificing quality.

Phase 04

Permitting

All plans submitted for municipal review. No construction begins until permits are properly secured.

Phase 05

Site Preparation

Clearing, grading, utility trenching, foundation installation — or structural reinforcement for conversions.

Phase 06

Construction

Framing through final finishes — roofing, plumbing, electrical, HVAC, insulation, cabinetry, flooring.

Phase 07

Inspections

Foundation, rough-in, and final inspections completed. Certificate of occupancy issued upon approval.

Phase 08

Completion

Final walkthrough, quality verification, and handover — ready for tenants, family, guests, or workspace.

How long does it take?

Timelines vary based on scope and permitting. Early planning and proactive coordination are key to maintaining schedule.
