Citrus Heights ADU Guide: Permits, Costs & PRADU Plans (2026)

Free house plans sound like they should end the conversation. Citrus Heights homeowners hear “PRADU” and picture a finished blueprint landing in their inbox, ready to hand straight to a contractor. That part is real: the city's Permit-Ready ADU Program puts three fully designed, city-approved floor plans in front of any property owner at no charge. What it doesn't do is finish the job. Your soil, your sewer lateral, your panel, your grading, none of that comes pre-approved. Every lot still needs its own look, plan or no plan, and that gap is the most useful thing to understand before pricing a project here.

What Citrus Heights' Free PRADU Plans Actually Save

The Permit-Ready ADU Program launched in 2021, funded by a state Local Early Action Planning (LEAP) grant through the Department of Housing and Community Development. It offers three designs: two 1-bedroom/1-bath models and a 2-bedroom/1-bath model, each with a choice of roof lines, exterior finishes, and interior layouts that include accessibility features like wider doorways and hallways. Every plan is also available in a mirrored, “reversed” format so it can be flipped to fit your side yard or driveway approach. According to local news reporting (not something we independently verified against a primary city figure), the program has drawn steady use since it launched in 2021, and ADU permit activity in Citrus Heights has kept climbing since.

Here's what “pre-approved” buys you: the architectural design work is done, and the structural plan review that a custom design would normally go through has already been completed once, by the city, for that plan. That skips real time and a real design fee, typically thousands of dollars most homeowners would otherwise pay an architect before they ever reach a permit counter.

Here's what it doesn't buy you. Every PRADU submission still goes through a site-specific review: grading and drainage, utility connections, setback and lot-coverage math, and, on a lot with soil concerns or an aging sewer lateral, its own engineering. The plan is pre-approved. Your lot isn't. The application also still requires a hold-harmless agreement and, in some cases, a right-of-entry authorization for the city's documentation. None of that is a knock on the program, it's a strong deal for anyone whose lot fits one of the three layouts. It just isn't a shortcut around foundation work, panel capacity, or a sewer line that needs replacing before an inspector signs off.

The Citrus Heights ADU Permit Process

California law makes ADU approval ministerial. If your plans meet the building and zoning code, the city has to approve them. No discretionary hearing, no neighbor vote, no planning commission sign-off required by state law, whether you're using a PRADU plan or a fully custom design.

Worth stating plainly, since it's an easy detail to assume wrong: Citrus Heights incorporated as its own city in 1997 and runs its own Building & Safety Division. An ADU permit for a Citrus Heights address doesn't route through Sacramento County, even though the city sits inside Sacramento County and shares its ZIP code range with several unincorporated neighborhoods nearby.

California's 60-day ministerial deemed-approved cap is the outer limit for a complete, code-compliant ADU application anywhere in the state, and that's the number we'd plan a Citrus Heights project against today. We weren't able to confirm a separate, published completeness-check window specific to the city's Building & Safety Division, so confirm current review times directly with the department before locking in a construction schedule. We'll handle that confirmation on your behalf once we're managing your submittal.

ADU Size, Height & Setback Rules in Citrus Heights (2026)

Detached ADU

• Maximum size: 1,200 square feet
• Height: 18 feet, with up to 2 additional feet allowed to match the primary home's roof pitch (up to 25 feet where the ADU sits above a detached accessory structure)
• Setbacks: 4 feet minimum, side and rear (front and street-side setbacks may run larger, per the underlying zoning district)
• Lot coverage: ADUs of 800 square feet or less are exempt from standard lot-coverage limits

Attached ADU

• Maximum size: up to 60% of the primary home's floor area, capped at 1,200 square feet; a 1-bedroom attached unit is capped at 850 square feet, a 2-or-more-bedroom unit at 1,000 square feet
• Height: 30 feet
• Setbacks: 5 feet side yard, 20 feet rear yard (may be reduced to 10 feet rear in some configurations)

Converting existing space (garage, converted room within the existing home)

• No additional setback required beyond what already exists

Junior ADU (JADU)

• Maximum size: 500 square feet, built within the walls of the existing or proposed home
• Owner occupancy required, in either the main home or the JADU, when the JADU shares a bathroom with the house

Parking

Convert an existing garage, carport, or covered parking structure into an ADU, and the city cannot require replacement parking. That's settled by state law, and it applies in Citrus Heights the same as anywhere else in California. Citrus Heights also does not add parking requirements on top of the state floor for most new ADUs.

That 1,200-square-foot detached ceiling and 18-foot height allowance give Citrus Heights more room than several neighboring cities' more conservative caps, particularly useful on the city's larger, older ranch-home lots. Whether your specific parcel can actually use that full ceiling depends on setbacks, existing structures, and lot coverage math, which is a separate question from what the code technically allows.

Citrus Heights ADU Costs (2026)

Per square foot: $200 to $280/sq ft for garage conversions; $265 to $380/sq ft for new detached construction at mid-range finishes.

Permit fee structure: Citrus Heights charges building permit fees on a valuation basis (tied to your project's estimated construction cost), plus two add-ons: a 6% General Plan Update Fee and a 4% Technology Fee, both calculated on top of the base permit fee. We didn't find a published flat-dollar range for a typical ADU permit, so the table below uses regional planning figures, not a Citrus Heights-specific number. Ask Building & Safety for a project-specific fee estimate once you know your unit's valuation.

A PRADU plan mainly cuts that architectural design line. Every other line item on this table still applies whether you're building the city's plan or your own.

Utilities: SMUD for Power, PG&E for Gas

Citrus Heights runs on SMUD, the Sacramento Municipal Utility District, for electricity. PG&E provides natural gas. These aren't competing options for the same service; SMUD is an electric-only utility and has never sold retail natural gas anywhere in its territory, so the two simply cover different utilities. A gas range, tankless water heater, or gas furnace runs through PG&E; everything else, including your ADU's electrical panel and service, runs through SMUD.

For a Citrus Heights ADU, most projects need to confirm whether the existing panel can carry a second kitchen, HVAC, and laundry load, or needs to step up from 100 amps to 200. Budget the regional typical range of $3,000 to $6,500 for that upgrade, and confirm the current SMUD application and connection process directly, since larger ADUs or a duplex meter setup can add its own timeline.

Water in Citrus Heights runs through one of several providers depending on the address, including Citrus Heights Water District, Sacramento Suburban Water District, or Cal American Water Company. Sewer runs through Sacramento Area Sewer District, and garbage service runs through Republic Services. Confirm which water provider serves your specific parcel before budgeting utility connection costs, since rates and connection fees differ between them.

Timeline: What to Expect

These are process-level ranges built from how ADU projects typically move through design, permitting, and construction across the region, not a Citrus Heights-specific published schedule. We manage the submittal, any corrections, and the coordination with SMUD so none of that timeline risk lands back on your calendar.

From Sylvan to Suburb: What Citrus Heights' Housing Stock Means for Your ADU

Citrus Heights didn't exist as its own city until January 1, 1997, when voters chose incorporation over staying unincorporated Sacramento County. Before that, the area was known as Sylvan, named for the oak-dotted countryside around Sylvan Corners, where Auburn Boulevard and Sylvan Road still cross today. A developer renamed the area Citrus Heights in 1910 to sound more appealing to prospective buyers, and the name stuck even after most of the citrus groves gave way to postwar tract development.

That postwar growth shapes ADU projects here now. Much of Citrus Heights filled in during the 1950s through 1970s with single-story ranch homes on generous lots, many with detached garages set back from the street, the kind of layout that makes a garage-conversion ADU or a small detached unit straightforward to site without fighting setbacks. The tradeoff on a lot this age: expect a higher chance of an undersized panel, an aging sewer lateral, or original cast-iron plumbing once a contractor opens things up, all of which feed into the site-specific costs a PRADU plan doesn't cover.

Sunrise Mall and the Birdcage Walk shopping district anchored the area's growth into a regional retail destination through the 1970s, and Citrus Heights today sits along the Highway 80/Business 80 corridor between Sacramento and Roseville, a location that keeps rental demand steady from commuters working in either direction.

Rental Income: What a Citrus Heights ADU Can Earn

Citrus Heights rents run near the middle of the Sacramento region. One-bedroom apartments have averaged roughly $1,400 to $1,650 a month in 2026, with two-bedrooms roughly $1,700 to $1,950. A private, well-finished ADU with its own entrance typically competes at or near those figures, sometimes above them if it's newly built with modern finishes against an older apartment stock.

A permitted, well-built ADU here typically adds $120,000 to $225,000 in appraised value, factoring in Citrus Heights' relative price point against the broader Sacramento region.
