In-Law Suite FAQs
The terms overlap. An in-law suite is typically an attached unit that shares some connection to the main house (internal door, shared entrance). An ADU has a separate, self-contained entrance and full kitchen. Regulatory definitions vary by city.
In most cases, yes — but check local short-term rental ordinances and HOA rules if applicable. An attached in-law suite may have slightly different rental rules than a fully detached ADU in some jurisdictions.
Bedroom, full bathroom, sitting room or kitchenette, and often a private entrance. Full kitchen capability makes it an ADU. The level of independence (internal connection vs. fully separate) affects both construction scope and local permitting.
Yes. Any new living space with plumbing, electrical, and structural work requires permits. We handle all permit applications and inspections.
