Accessory Dwelling Units (ADU)

What is an adu

Accessory dwelling units — also called ADUs, secondary units, or granny flats — are small living units, including a kitchen and bathroom, on a property that has one single-family home.

There are many benefits to ADUs, including that they: Create more affordable housing for our community, family members, or disabled persons; Provide an income opportunity for homeowners; Promote infill development; and Encourage the use of public transportation.

a'part ADU's are all factory built and HCD complaint. We can even help with the zoning applications, installations and final approvals.

In most cities that would be a big …. Yes.
In most cities ADUs can have a porch. If the porch is uncovered, it will not count toward the maximum floor area allowed.

The answer is possibly. In some cities the primary house will not be reassessed, and your base assessment of the primary house will not be affected, but your taxes will increase based on the value of the ADU.
When you chose an a’partment we will handle the planning for your ADU. Our service includes the submission of the plans with a Building Permit Application at the Permit Center. City staff will review the plans for compliance with the building code; once approved and all fees are paid, they will issue a building permit.
These change by city however commonly the the building permit fee depends on the square footage of the ADU.

In many cities other small fee’s may also apply including but not limited to
School fees
Park Impact fees
Fees for any clearances or other permits as may be applicable, such as a Geohazard Clearance, Tree Removal Permit, or a Fire Variance, for example.
In cities which have a need for housing the process is quick, typically around 20 – 30 business days unless your plan requires more than a first review.
