An Accessory Dwelling Unit (ADU) is a permanent dwelling unit that may share at least one wall with the primary residence (attached) or be a stand-alone structure (detached) from the primary residence. ADUs provide permanent facilities for living, sleeping, eating, cooking and sanitation.
(City of Sacramento, Commnity Development).
Rules/codes:
- 1,200 ft2 max size per lot/parcel.
- Attached ADUs may be 50% of the primary structure or a maximum of 850 ft2, whichever is greater.
- Attached ADUs with two or more bedrooms may be 50% of the primary residence or a maximum of 1,000 ft2, whichever is greater.
- ADUs must also comply with all
applicable provisions of the current California Building Code (CBC), Residential (CRC), Energy
(CEnC), Plumbing (CPC), Mechanical (CMC), Electrical (CEC), and local ordinances. - Planning approval or an approval for concurrent review must be obtained prior to submitting a building permit application to the Building Division. You can request a concurrent review by turning in a Memorandum of Understanding Concurrent Plan Review Request. This request must be approved by Senior Planning division staff.
Project costs will vary depending on the type of ADU (e.g. detached, attached, modular, etc.) being constructed. Typically, 80% of the total project budget costs can be expected for construction (materials and labor), with another 20% for consulting, design and permitting fees. Typically, the longer the construction timeline, the more costs incurred.
