ADU for Whittier homes

Whittier is our home city, and ADUs are a natural fit for it. Many lots hold a 1940s to 1960s house with a long back yard and a detached garage, and many families here are looking for space for parents, adult children or rental income.

We know the city’s building department and how it likes plans presented. We also know what is behind the walls of Whittier’s older houses, which matters when an ADU needs to connect to old plumbing, a small electrical panel or a raised foundation.

What matters in Whittier

Detached garages

Old garages can be converted or replaced. We check the slab and structure before deciding which is better.

Old utilities

Older sewer and electrical service often needs upgrades to support a second unit.

Hillside lots

In East Whittier, slope and drainage influence where and how a unit can be built.

How we work

Site visit. We measure, photograph and look at what the property allows.
Written scope. You receive a written scope and price for your project. Pricing is individual and depends on the property and the scope.
Plans and permits. We prepare the drawings and manage the permit process.
Build and inspection. Licensed crews build, the city inspects, and we walk through the finished work with you.
