An ADU builder in Citrus Heights is a licensed contractor who designs and constructs accessory dwelling units — detached backyard units, garage conversions, attached additions, and junior ADUs (JADUs). Because an ADU is a complete second dwelling, the builder coordinates foundation, framing, plumbing, electrical, and HVAC work and pulls it through Citrus Heights's permit process and utility connections. Not every general contractor has built one, so the right builder is one with ADU-specific experience in California.
What ADU Builders Cost in Citrus Heights [10]
Based on our Citrus Heights cost data, expect the following ranges from local ADU builders. Quotes for the same scope typically vary 20-40% between contractors, so getting at least three bids is the single best way to control cost.

| Cost per Sq Ft | $250-$400 |
| Garage Conversion | $80,000-$150,000 |
| Prefab / Modular ADU (installed) | $120,000-$250,000 |
| City Permit & Plan Review | Confirm current building permit and plan check amounts with Citrus Heights Planning at (916) 727-4740 — no ADU fee schedule is published on the city's ADU pages |
| Impact Fees | Confirm with Citrus Heights Planning — California law limits impact fees on smaller ADUs, but the city publishes no ADU-specific fee schedule; ask the Planning Division which fees apply at your unit's size before you budget |
For a full line-item breakdown, see our Citrus Heights ADU cost guide. To confirm what you're allowed to build before you hire, review the Citrus Heights ADU rules (max detached size: Local option: 1,200 sq ft regardless of the size of the primary dwelling (Citrus Heights Zoning Code §106.42.015.D.3.b) — but a detached unit over 800 sq ft must also meet the zoning district's lot coverage limit, which the city's ADU page puts at 30%-50% depending on zone. State option: 800 sq ft with four-foot side and rear setbacks, which no local standard may preclude (Gov. Code §66323(a)(2) and §66321(b)(3)); owner-occupancy: Not required for an ADU. For a JADU, the current local code requires either the JADU or the residence containing it to be owner-occupied, with a deed restriction recorded before permit issuance (Citrus Heights Zoning Code §106.42.015.D.7.b-c). AB 1154, effective January 1, 2026, narrows that to JADUs that share sanitation facilities with the primary dwelling, and the city's pending amendment adopts the narrower rule — confirm with Citrus Heights Planning which applies to your permit).

How to Vet an ADU Builder in Citrus Heights
- License: Confirm a current contractor's license in California and that it's in good standing. Ask for the license number and verify it with the state board.
- ADU-specific experience: Ask how many ADUs they've completed in or near Citrus Heights and request addresses or photos. ADU permitting and setbacks differ from a kitchen remodel.
- Portfolio & references: Get references from recent ADU clients and, if possible, visit a finished unit.
- Insurance: Verify general liability and workers' compensation coverage. Ask for a certificate of insurance.
- Written, detailed bid: Insist on an itemized, fixed-price or clearly-scoped bid — not a verbal estimate. It should state whether permits (Confirm current building permit and plan check amounts with Citrus Heights Planning at (916) 727-4740 — no ADU fee schedule is published on the city's ADU pages), plan check (Building Division plan check. The city's permit-ready plans come pre-approved by the Building Division, which shortens review. Fire sprinklers are not required for an ADU or JADU if they are not required for the primary dwelling), and impact fees (Confirm with Citrus Heights Planning — California law limits impact fees on smaller ADUs, but the city publishes no ADU-specific fee schedule; ask the Planning Division which fees apply at your unit's size before you budget) are included.
- Permit handling: Confirm they manage Citrus Heights's permit process ("Ministerial — considered and approved without discretionary review or a hearing (Gov. Code §66317(a)(1)); the Director issues a Zoning Clearance under Citrus Heights Zoning Code §106.42.015.E. Per the city's February 10, 2026 letter to HCD, an applicant may elect either the city's local ADU/JADU program or the state provisions at Gov. Code §§66310-66342 while the code update is pending", typically Completeness determination within 15 business days of submittal; approve or deny within 60 days of a complete application where a dwelling already exists on the lot — and if the city misses the 60 days, the application is deemed approved (Gov. Code §66317(a)(2)-(3))) and who is responsible if revisions are required.
- Payment schedule: Avoid large upfront payments. A reasonable schedule ties payments to completed milestones.

Code §66317(a)(2)-(3))) and construction?
