In-Law Suite FAQs
In-law suites are typically attached to the main home or within it. ADUs are often detached. Zoning rules differ—in-law suites may have fewer restrictions but often can't be rented to non-family.
A separate entrance adds privacy and independence, but isn't always required by code. We can design connected or independent access based on your family's needs.
Possibly, but zoning may limit kitchens in attached units. Kitchenettes with no stove/oven are often permitted. We'll navigate your local requirements.
Any addition that increases square footage will likely increase assessed value. However, the added living space also increases property value, typically by more than the tax increase.
