Yes. Citrus Heights approves ADUs ministerially under Zoning Code §106.42.015, rewritten in full by Ordinance No. 2026-004 (adopted June 10, 2026, effective July 10, 2026) to track Government Code §§66310-66342. You pick one of two pathways and cannot mix them: the local option (one ADU, detached up to 1,200 sq ft, plus one 500 sq ft JADU) or the state §66323 option (one conversion ADU, one JADU and one new detached ADU up to 800 sq ft). Under both, side and rear setbacks are 4 ft, a detached unit may be 18 ft plus 2 ft for roof pitch, no parking is required, the ADU has no owner-occupancy rule, and one ADU up to 800 sq ft is exempt from lot coverage. Three free permit-ready plans (496, 599 and 749 sq ft) are pre-approved by the Building Division; a $200,000 build pays roughly $5,300 in city permit and plan-check fees, and the city's $5,399 impact-fee package applies only to units of 750-1,200 sq ft (state law exempts 750 sq ft of interior livable space or less).
Zoning & Size Requirements [1][2][3][4][5][6][7][8]
Yes — Citrus Heights allows ADUs. A detached ADU can typically be up to 1,200 sq ft under current California and Citrus Heights zoning rules.

| Allowed Zones | Any lot with an existing or proposed primary unit, duplex or multi-unit dwelling (Zoning Code §106.42.015.A.1, as replaced by Ord. No. 2026-004). Table 2-2 lists an ADU as a permitted use in every residential and open-space zone: RD-1 through RD-30, MH and O (§106.24.030). A JADU is allowed only on a single-family-zoned lot with a single-family home (§106.42.015.D). State law also requires ministerial approval in any residential or mixed-use zone with a dwelling (Gov. Code §66323(a)). |
| Max Size (Detached) | Local option: 1,200 sq ft regardless of the primary home's size (§106.42.015.B.3.b), measured as interior livable space from the inside face of the exterior walls, excluding garages, porches and unfinished space (E.4). Above 800 sq ft the zone's lot coverage applies: 30% in RD-1 to RD-4, 50% in RD-5 to RD-15 (Table 2-4). State option: 800 sq ft (§106.42.015.C.1.a(3); Gov. Code §66323(a)(2)). No local standard may block an 800 sq ft unit with 4-ft side and rear setbacks (Gov. Code §66321(b)(3)). |
| Max Size (Attached) | 60% of the existing primary dwelling's floor area, up to 1,200 sq ft, but never less than 850 sq ft for a studio or one-bedroom or 1,000 sq ft for two or more bedrooms (§106.42.015.B.3.a; Gov. Code §66321(b)(2)). The 2026 rewrite adds that no local standard such as FAR or lot coverage may be applied to prohibit at least one attached ADU of at least 800 sq ft. A state-option conversion of an accessory structure may add up to 150 sq ft for ingress and egress only (§106.42.015.C.1.a(1)). |
| Max Size (JADU) | 500 sq ft of interior livable space, created within the walls of the proposed or existing single-family home including an attached garage, with at least an efficiency kitchen, its own exterior entrance, and either a private or a shared bathroom (§106.42.015.D.1). One JADU per lot under either pathway. A recorded deed restriction barring separate sale must be shown before the building permit issues (§106.42.015.D.3; Gov. Code §66333). |
| Max Height | Detached: 18 ft, plus 2 ft to match the primary home's roof pitch (§106.42.015.E.2.b); 25 ft where the ADU sits above a detached accessory structure (E.2.c). Attached: the zoning district's limit, 30 ft in the single-family RD zones (Table 2-4; city ADU Development Standards page), or more where state law allows (E.2.a). The three permit-ready plans are drawn at 16 ft. |
| Max Units | Single-family lot, local option: one ADU plus one JADU (§106.42.015.B.1.a). State option: three units, one interior or conversion ADU, one JADU and one new detached ADU up to 800 sq ft (§106.42.015.C.1.a; Gov. Code §66323(a)(1)-(2)); the options may not be combined (A.2). Multi-unit lots follow state law either way: conversion ADUs in non-livable space (one to 25% of units) plus one detached ADU per existing unit up to eight, or two on a proposed building, no floor-area cap (C.1.b). |
Setback Requirements [1][2][3][4][5][6][7][8]
Citrus Heights requires a rear setback of about 4 ft for a detached ADU, and no additional parking is required. Owner-occupancy is not required — you can rent it out without living on the property.
| Rear Setback | 4 ft for a newly built ADU (§106.42.015.E.1); none for converting, or rebuilding in place, an existing structure (E.1.a). The city's ADU web page and FAQ, written before the 2026 rewrite, still show a 20-ft rear yard for attached ADUs (reducible to 10 ft); the adopted code and Gov. Code §66314(d)(7) cap side and rear setbacks at 4 ft for any new ADU, so ask Planning at (916) 727-4740 before designing to 20 ft. No ADU may sit in an easement without the holder's written consent (E.1.b). |
| Side Setback | 4 ft for a newly built ADU (§106.42.015.E.1); none for conversions of existing structures (E.1.a). The city's pre-rewrite ADU page lists a 5-ft side yard for attached ADUs, but the adopted code applies the 4-ft figure to any ADU and Gov. Code §66314(d)(7) bars a local side setback of more than 4 ft for a new ADU. Second-floor windows within 10 ft of a side lot line must be obscured or clerestory, and balconies above the ground floor must stay 10 ft from side and rear lines (E.9). |
| Front Setback | The front and street-side setbacks of the underlying zone apply (20 ft front in RD-1 to RD-4, 15 ft in RD-5/RD-7, Table 2-4) and ADUs are prohibited in the front yard under the local option (§106.42.015.B.2), except that a front setback may not be applied if it would prohibit an attached or detached ADU of up to 800 sq ft with 4-ft side and rear setbacks (§106.42.015.E.1.c). |
| Parking Required | None. No additional off-street parking is required for an ADU or JADU, and when a garage, carport or parking space is demolished or converted for the unit, no replacement parking is required (§106.42.015.E.7; Gov. Code §66314(d)(11)). |
| Owner Occupancy | Not required for an ADU. For a JADU, owner-occupancy (in either the JADU or the main home) is required only if the JADU shares a bathroom with the primary dwelling; a JADU with its own sanitation facilities, or one owned by a government agency, land trust or housing organization, is exempt (§106.42.015.D.2, tracking AB 1154 and Gov. Code §66333(b), effective January 1, 2026). |
| Min Lot Size | No minimum lot size. State law bars minimum-lot-size standards for ADUs (Gov. Code §66314(b)(1)), and neither the ADU nor the JADU counts toward the parcel's density (§106.42.015.B.1.a). Minimum parcel sizes in Table 2-3 (for example 8,500 sq ft in RD-4) govern subdivisions, not ADUs. |
Permit Process & Fees [9][10][11][12][13][14][15][16][17][18][19][20]
An ADU permit in Citrus Heights goes through a ministerial, by-right review. Review time: not published by the city. State law requires a completeness notice within 15 business days and a decision within 60 days of a complete application where a home already exists, otherwise the application is deemed approved (Gov. Code §66317(a)(2)-(3)); §106.42.015.F binds the city to those timelines. Permit fees: Valuation-based (Master Fee Schedule, February 1, 2026): a $200,000 ADU pays about $2,933 building permit plus 65% plan check ($1,906), 6% General Plan and 4% technology surcharges, a 3.25% zone check and $94 issuance, roughly $5,300 in all; get a quote from Building at (916) 727-4760.
| Approval Process | Ministerial building permit. §106.42.015.F (Ord. 2026-004) requires the city to process every ADU and JADU application ministerially within the timelines of Gov. Code §66310 et seq.; zoning compliance is checked inside the building-permit review (a 3.25% Planning zone-check fee), not through a separate hearing. Apply through the Citizen Access Portal. Applicants choose the local option (subsection B) or the state §66323 option (subsection C) on the application. |
| Review Timeline | Not published by the city. State law requires a completeness notice within 15 business days and a decision within 60 days of a complete application where a home already exists, otherwise the application is deemed approved (Gov. Code §66317(a)(2)-(3)); §106.42.015.F binds the city to those timelines. |
| Permit Fees | Valuation-based (Master Fee Schedule, February 1, 2026): a $200,000 ADU pays about $2,933 building permit plus 65% plan check ($1,906), 6% General Plan and 4% technology surcharges, a 3.25% zone check and $94 issuance, roughly $5,300 in all; get a quote from Building at (916) 727-4760. |
| Impact Fees | State law bars impact fees on an ADU of 750 sq ft of interior livable space or less and a JADU of 500 sq ft or less (Gov. Code §66311.5(c)). The city's Impact Fee Schedule (January 1, 2026) marks smaller ADUs EXEMPT and charges an ADU of 750-1,200 sq ft $1,467 multimodal + $3,045 park + $887 fire facility = $5,399, half the single-family rate. Separately, San Juan USD school fees apply from 500 sq ft (916-971-7073) and sewer connection charges are set by SASD/SRCSD (916-876-6100), which state law lets them charge proportionately for a new detached unit but not for a conversion or JADU. |
| Plan Check | Building Division plan check at 65% of the building permit fee, due at submittal; extra review cycles cost $177 each and outside plan-check consultants beyond the second cycle are billed at cost (Master Fee Schedule). The free permit-ready plans are already approved by the Building Division, so only the site plan and site-specific items (utilities, solar, easements) are reviewed. Fire sprinklers are not required unless the primary home has them (§106.42.015.E.5). Each ADU is also subject to the state solar requirement, which may be met on the main house. |
| Pre-Approved Plans | Yes. The Permit-Ready ADU Program (LEAP-grant funded) offers three city-owned plan sets free of charge: a 496 sq ft one-bedroom, a 599 sq ft one-bedroom and a 749 sq ft two-bedroom, each 16 ft tall with a choice of roof lines and exterior finishes, accessible features and a mirrored layout; all are pre-approved by the Building Division (drawn to the 2019 California Residential Code, so confirm the current set with Building before you order). The city also accepts designers' plans for AB 1332 pre-approval (Gov. Code §65852.27), but as of September 2026 no vendor has submitted any, so the Preapproved Vendor list is empty. |

Recent Law Changes
What's Changed Recently
- Ordinance No. 2026-004, adopted June 10, 2026 by a 5-0 City Council vote on second reading (introduced May 27, 2026) and effective July 10, 2026, replaced Zoning Code §106.42.015 in its entirety; Municode shows the code codified through this ordinance (Supp. No. 33, posted August 26, 2026)
- The rewrite codifies two pathways an applicant chooses between and may not combine: the local option (one ADU up to 1,200 sq ft detached plus one JADU) and the Gov. Code §66323 state option (three units, detached capped at 800 sq ft); multi-unit lots follow state law under both
- New in the adopted text: a 4-ft side and rear setback for any new ADU, an easement rule (written permission from the easement holder or a sworn declaration), an 800 sq ft attached-ADU floor that lot coverage and FAR cannot defeat, an interior-livable-space definition of floor area, a 150 sq ft efficiency-unit minimum, and removal of the local floor-area cap on detached ADUs at multi-unit properties
- JADU owner-occupancy narrowed to units that share a bathroom with the main home (§106.42.015.D.2), matching AB 1154 (effective January 1, 2026)
- ADU amnesty added at §106.42.015.G for units built without permits before January 1, 2020: ministerial approval unless the Building Official finds the unit substandard, no enforcement while an application is processed in good faith, available until January 1, 2030; the state statute is Gov. Code §66311.7 (renumbered from the former §66332 by SB 543), which also waives impact and connection fees for these units
- The February 10, 2026 city letter to HCD, and the city's ADU Development Standards page, still describe the code update as pending; the page's attached-ADU setbacks (5 ft side, 20 ft rear) and its 2024-era wording have not yet been updated to the July 2026 code
- State overlay in force in 2026: SB 543 (60-day deemed approval and a deemed-complete rule if the city misses the 15-business-day completeness notice, Gov. Code §66317) and the renumbering of the impact-fee section to §66311.5
Tips for Building an ADU in Citrus Heights
- Pick your pathway before you design: the local option gives you one detached ADU up to 1,200 sq ft, the state option gives you three units but caps the new detached one at 800 sq ft. You cannot mix them (§106.42.015.A.2)
- Two size lines matter: at 800 sq ft or less you are exempt from lot coverage (§106.42.015.E.3), and at 750 sq ft of interior livable space or less you pay no city impact fees (Gov. Code §66311.5(c)). The city's 749 sq ft two-bedroom permit-ready plan is sized to sit inside both lines
- Fee basis: the $5,300 permit figure is the Master Fee Schedule's valuation formula on a $200,000 job ($2,315 for the first $100,000 plus $6.18 per $1,000 after, then 65% plan check, 6% General Plan and 4% technology surcharges, 3.25% zone check, $94 issuance); a $120,000 job comes to roughly $4,400. Impact fees are extra only at 750-1,200 sq ft: $5,399 to the city plus school and sewer charges from outside agencies
- The city's Impact Fee Schedule labels its exemption as applying to units smaller than 750 sq ft while Gov. Code §66311.5(c) exempts a unit at exactly 750 sq ft of interior livable space; if you land on 750, cite the statute
- Start with the free permit-ready plans: 496 sq ft (Magnolia, Mariposa or Maple exteriors), 599 sq ft (Sycamore) or 749 sq ft (Pine or Oak), all pre-approved by the Building Division and flippable to suit your lot. Submit through the Citizen Access Portal with a site plan, the hold-harmless agreement and the plan name
- Converting a garage or other legal existing structure needs no setback at all, no replacement parking, and is not treated as a change of occupancy unless the Building Official finds a safety reason (§106.42.015.E.1.a, E.6, E.7)
- If a reviewer applies the 5-ft side or 20-ft rear setback shown on the city's older ADU web page to an attached ADU, point to §106.42.015.E.1 as amended by Ord. 2026-004 and Gov. Code §66314(d)(7), which limit side and rear setbacks for any new ADU to 4 ft
- Track the clock: 15 business days for the completeness notice, 60 days to approve or deny a complete application, then deemed approval (Gov. Code §66317(a)(2)-(3))
- Renting it out: you sign an ADU Rental Restriction Acknowledgment Form at permit application, and every rental must be registered with the Rental Housing Inspection Program ($65 a year for one unit plus a $27 housing stock fee, city Finance page)
- Have an unpermitted ADU built before 2020? The amnesty pathway (§106.42.015.G) lets you legalize it without penalties; the city posts an ADU Amnesty Assessment Checklist and suggests a confidential third-party inspection first. Call Building at (916) 727-4760
- Cost basis: build, per-sq-ft, garage and prefab ranges are the Sacramento-region figures from four 2026 contractor cost guides (updated April to June 2026), not Citrus Heights quotes; rents bracket HUD's FY2027 Small Area Fair Market Rents for ZIP 95621 ($1,800 one-bedroom, $2,210 two-bedroom) and ZIP 95610 ($1,910 and $2,340), effective October 1, 2026
