AfterFast, Reliable Home Additions & ADU Across Citrus Heights
Most room additions and ADU projects in Citrus Heights cost between $45,000 and $220,000, depending on the scope, the condition of your existing slab, and how much site prep your parcel requires. If you’re calling around Citrus Heights for a garage conversion, a second-story addition, or a new detached ADU, you’ll hear a lot of numbers. What you won’t hear from most companies is which questions to ask before you sign. That’s the part we focus on. Call (877) 610-1318 and we’ll walk your property with you, look at the existing conditions, and give you a written, line-item scope before any money changes hands.
We know the ranch-style tract homes off Sunrise Boulevard and the acreage parcels east of Fair Oaks Boulevard because we’ve worked on them for years. The soil here doesn’t behave like it does ten miles away. That matters when you’re adding square footage, and we’ll tell you why it changes the price.
Why Barrett & Sons Construction Is Citrus Heights’s Preferred Home Additions & ADU Company
We’re not a franchise operation. Tom Barrett founded this company in 1998, and his sons run the crews you’ll see on your property. The name on the truck is the name on the contract. When a Citrus Heights homeowner calls our office, a live person answers the phone 24 hours a day. Not a voicemail box. Not an out-of-state call center. You can verify Tom’s name, address, and license number before you sign anything, and we encourage you to.
Local reputation matters in a city like Citrus Heights, where the housing stock dates back to the 1950s and 1960s and neighbors talk. Our Home Additions & ADU work in Citrus Heights has been built on one simple rule: every price change arrives in writing before work proceeds. Every permit that’s eligible gets pulled, and every inspection gets signed. That’s why homeowners across Citrus Heights keep our number in their phone, and why they answer when a neighbor asks who did their addition.
We’re local enough to know the difference between a 95610 parcel near San Juan Avenue and a 95621 lot off Antelope Road. The permit history, the soil, the setback rules, the access for material deliveries: these things vary within Citrus Heights itself, and they all affect your project’s real cost. We scope for them before we quote, not after you’ve signed.
Our Home Additions & ADU Services in Citrus Heights
ADU Design & Permitting
Designing an ADU in Citrus Heights starts with the parcel. Many of these lots predate the city’s 1997 incorporation, which means permit records often sit in two systems: the City of Citrus Heights and the Sacramento County Archives. We handle that search for you, because missing an old unpermitted patio enclosure or garage conversion will stop a project mid-frame. Expect design and permitting for an ADU in Citrus Heights to include a title search, a soils check, and a clear scope of what’s legally allowed on your specific lot. A new detached ADU here typically runs $90,000 to $220,000, and the permit fees and records work should be line-itemed before you sign.
Garage Conversion ADU
Converting an attached garage into a junior ADU or full ADU is often the fastest path to extra square footage in Citrus Heights. Most of these ranch homes have attached two-car garages with slab floors from the 1960s or 1970s. The garage slab may not have a vapor barrier or insulation under it, and it may not meet current code for living space. We assess that before we quote, because converting a garage into living space in Citrus Heights generally lands between $30,000 and $80,000, and the slab preparation is what moves that number.
New Detached ADU
If you’re on one of the larger parcels east of Fair Oaks Boulevard or north of Greenback Lane, a detached ADU may be the better play. On acreage, well and septic setbacks can push your ADU footprint around. In Sacramento County, a new septic system or well often requires 100 feet of separation, and that can force your build site into a drainage swale or farther from existing utilities. We walk the lot before we draw. New detached ADU construction in Citrus Heights runs $90,000 to $220,000, and the largest cost swings come from grading, utility trenching, and concrete foundation depth, not the framing.
Junior ADU & Interior Conversion
A junior ADU, typically under 500 square feet, is a practical option for a Citrus Heights homeowner who wants rental income or an aging parent on the property without a full separate structure. These projects often use existing interior space, like a portion of the home or an enclosed patio. A junior ADU in Citrus Heights can start in the low five figures, but the permit still has to be pulled, and the work has to pass inspection. We scope the walls, electrical panel capacity, and egress windows up front.

Common Home Additions & ADU Problems We See in Citrus Heights Homes
- Slab heave at the tie-in point. Most homes here were slabbed in the 1960s without engineered soil prep, so the existing slab and your new footings move at different rates. Without a soils report and deeper perimeter footings, the shared wall cracks within two wet winters.
- Missing permit records from before 1997. Citrus Heights incorporated in 1997, and many pre-incorporation permits live in Sacramento County Archives. A records search often turns up an old garage conversion or patio enclosure with no final inspection, which triggers a stop-work order if it’s not cleared before your project starts.
- Septic and well setback conflicts on acreage. On larger parcels, a detached ADU can’t be placed anywhere you like. Septic separation rules may force the footprint into a drainage swale or a corner of the lot, which means grading and retaining walls you didn’t budget for.
- Undersized electrical panels. Original 100-amp service is standard on these 1950s-1970s tract homes. Adding an ADU or a second-story addition usually requires a panel upgrade, and that cost should be in your quote from day one, not introduced as a “discovery” later.
Pricing for Home Additions & ADU in Citrus Heights, CA
Here’s what we tell Citrus Heights homeowners before we ever write a contract:
| Project | Typical Citrus Heights Range |
|---|---|
| New Detached ADU | $90,000-$220,000 |
| Room Addition | $45,000-$130,000 |
| ADU Site Prep & Utilities | $8,000-$30,000 |
Those numbers come from years of working in Citrus Heights, not from a national cost database. A 400-square-foot room addition on a 1963 slab off San Juan Avenue costs differently than the same addition on a newer lot in Roseville, because the soil under the slab matters. So does the permit history on your home. We’ll give you a free estimate that includes the soils assessment, the records search, and every line item in writing. Call (877) 610-1318 to schedule that estimate, and you’ll know exactly what you’re paying for before you sign.

FAQs - Home Additions & ADU in Citrus Heights
Yes. A slab without visible cracks can still be sitting on expansive clay that moves seasonally, and a new footing placed without a soils report may heave at a different rate than the existing slab. A soils report for a Citrus Heights room addition typically costs a few thousand dollars and it’s worth every cent: it tells us how deep to place your footings so the shared wall doesn’t crack within two wet winters. Call (877) 610-1318 and we’ll explain what the report covers for your specific lot.
On an acreage parcel in the 95621 zip code, a detached ADU typically triggers well and septic setback verification, a grading plan if the build site sits in a drainage path, and a soils report for frost-line and expansive-clay requirements. Roseville city lots are often on engineered fill and have sewer connections, so those steps get skipped. If your Citrus Heights parcel has an existing well or septic system, expect the county to require separation distances and possibly a percolation re-test. We scope all of that before we quote, and we’ll put every fee in writing.
Yes, in most cases. Citrus Heights allows junior ADUs within existing homes, including attached garages, as long as the conversion meets current code for egress, insulation, ceiling height, and electrical. Parking requirements vary by neighborhood and by whether your street has any off-site parking relief programs. A junior ADU conversion in Citrus Heights usually costs less than a full detached ADU because the foundation and roof are already there, but you’ll still need a permit and final inspection. We’ll check your specific street’s parking rules during the estimate.
They add time, and time adds money. A second-story addition on a Citrus Heights home requires engineered lumber, Andersen or Marvin Windows & Doors in Citrus Heights, and often full roof replacement with GAF shingles. If materials come from out of the area, you’re paying for freight and for your crew’s scheduling flexibility. If a crane is needed to set beams, access from streets like Sylvan Road or Auburn Boulevard can complicate the setup. We order local when we can, and we’ll tell you which material choices add the most time to your timeline.
A sunroom or enclosed patio addition on a pre-1997 Citrus Heights home can run from $45,000 to $130,000, depending on whether the original structure was permitted, whether the slab has shifted, and whether the roof ties in cleanly. The unknown permit history is the real cost driver: we search Sacramento County Archives and City of Citrus Heights records before quoting, and if an old patio enclosure was never finalized, we pull a new permit that covers both the old work and the new addition. That added step can save you a stop-work order later. Call (877) 610-1318 and we’ll pull the records for your home before you decide anything.
If you’re ready to talk about an addition or ADU on your Citrus Heights property, call (877) 610-1318. We’ll answer the phone, walk the lot with you, and give you a free written estimate that covers everything we talked about here. Scope in writing, allowances in writing, change orders in writing.
