Sacramento rules that affect a attached adu
In Sacramento, an attached unit shares a wall and utility runs with your main home, which can cut trenching and site costs — useful on tighter lots where a fully detached build would crowd the yard. The City of Sacramento Community Development Department reviews it as new attached square footage.
Local permitting: Within City of Sacramento limits, detached ADUs follow a 4 ft side/rear setback, a 16 ft height limit (taller near transit), and require no replacement parking. The city's pre-approved ADU plan set and ADU Resource Center can drop plan check to roughly 30 days, and units under 750 sq ft are exempt from impact fees.
That's the attached adu-specific picture. For the full Sacramento County rulebook — every setback, height, and owner-occupancy detail — see our Sacramento-region ADU rules guide, and learn how the build type works statewide on our attached adu page.

Sacramento attached adu permits are handled by the City of Sacramento Community Development Department (ADU Resource Center). Within City of Sacramento limits, detached ADUs follow a 4 ft side/rear setback, a 16 ft height limit (taller near transit), and require no replacement parking. The city's pre-approved ADU plan set and ADU Resource Center can drop plan check to roughly 30 days, and units under 750 sq ft are exempt from impact fees. We prepare and submit the full package and manage inspections.
A attached adu in Sacramento rents for about $1,500–$2,800 a month in 2026 depending on size and finish. Older deep lots in Land Park, East Sac, and Tahoe Park rent fast to Midtown and downtown commuters, so a 750 sq ft unit often clears $2,000+/mo and pays back in roughly 9–13 years before appreciation.
An attached ADU shares at least one wall with your main house; a detached ADU is a standalone structure. Attached units can be cheaper to build (shared utilities, less site work) while detached units typically rent higher and add more resale value.
