AfterFast, Reliable Home Additions & ADU Across Citrus Heights
A home addition or ADU in Citrus Heights typically runs $45,000 to $130,000 for a standard room addition, while a full detached ADU lands between $90,000 and $220,000. We scope every job in writing before the first nail moves, so you know the exact number you’re signing. If you’re thinking about adding space to a 1950s or 1960s ranch in Citrus Heights, call Tom Barrett at (877) 610-1318 and we’ll walk the property with you, old permit records and all.
Why Barrett & Sons Construction Is Citrus Heights’s Preferred Home Additions & ADU Company
We’ve pulled permits for additions and ADUs all over Citrus Heights, from the tree-lined streets near Sylvan Corners to the acre lots off Old Auburn Road. This is not a franchise sending strangers to your door. Tom Barrett and his sons run the crews, and the name on the truck is the name on the contract. When a Citrus Heights homeowner calls us about a 1963 ranch that needs a second story or a detached ADU out back, we already know the soil, the slab, and the panel situation before we ring the bell.
The pre-1997 homes here have a paperwork problem most contractors never mention until inspection day stalls. Any addition or ADU on a property built before Citrus Heights incorporated in 1997 has permit and inspection records split between Sacramento County Archives and the City of Citrus Heights. That dual-records chase is real, it takes time, and Roseville jobs rarely deal with it. We budget for it up front so it doesn’t become a change order surprise halfway through your build.
Our 90-Day Done Right Promise is written on every Citrus Heights contract. If something isn’t right after the final inspection, Tom comes back and makes it right. One call. That’s the whole promise.
Our Home Additions & ADU Services in Citrus Heights
We offer the full Home Additions & ADU scope across Citrus Heights, from a 300-square-foot junior ADU off a garage to a two-story addition on a half-acre lot. The sub-services below are the ones Citrus Heights homeowners ask about most, and each one gets scoped differently depending on your lot, your foundation, and your permit history.
ADU Design & Permitting
This is where Citrus Heights jobs live or die. For pre-1997 homes, we chase both the Sacramento County Archives and the City of Citrus Heights before we draw a single line. The missing paper we find (or don’t find) changes the timeline and the price. We handle drawings, submittals, and every inspection sign-off. You won’t stand in line at the permit counter unless you want to.
New Detached ADU
A detached ADU on a Citrus Heights acre lot starts with setbacks. County septic and well setbacks can eat 20% of your usable yard before you pour one footing. We map those clearances first, then size the unit. On a 1960s ranch off Greenback Lane, our crew scoped a 480-square-foot detached ADU on an acre lot with an aging septic system. County setbacks pushed the build past the existing leach field, and the original 100-amp panel couldn’t carry the new subpanel, so we priced a 200-amp service upgrade and a 30-foot directional bore for power before the first footing was dug. That’s the job done on paper before we dig.
Garage Conversion ADU
Converting an attached garage in Citrus Heights usually lands between $30,000 and $80,000. The wild card is the panel. If your 1960s tract home still runs a 100-amp service, you’re adding a subpanel and probably a service upgrade. We check that before we quote, because the last thing you want is a conversion that trips the breaker every time the AC kicks on in July.
Junior ADU & Interior Conversion
A junior ADU inside the existing footprint of your Citrus Heights home is the fastest path to rental income or a quiet in-law suite. These conversions usually avoid the septic and setback fights that detached units trigger, but the panel and the egress window requirements still apply. We pull the permit and sign off the inspection, same as a full build.

Trusted Brands We Service in Citrus Heights
We install materials you can look up, not mystery brands off a van. On Citrus Heights additions and ADU jobs, that often means Schluter systems under bathroom tile, Grohe fixtures in the wet areas, and GAF shingles when the roof line changes. If you see a brand name on our quote, you can walk into any supply house in the Sacramento area and verify what it costs. We don’t hide behind allowance games.
Common Home Additions & ADU Problems We See in Citrus Heights Homes
- Shear cracks at the seam. Tying a new addition onto a 1960s slab without a soil compaction test on expansive clay invites trouble. The wet-dry cycle in Citrus Heights opens a shear crack at the seam within two winters. We test the soil before we draw the foundation plan.
- Septic and well setbacks killing the build. A conforming Citrus Heights lot with a septic system can lose 20% of usable yard to required clearances. We map those before we quote, not after the county flags it.
- The 100-amp panel bottleneck. 1950s through 1970s Citrus Heights tract homes were built with 100-amp panels. An ADU subpanel or a second-story heat pump pushes you to a 200-amp upgrade. We check the panel before we send the quote.
- The split permit record stall. Pre-1997 Citrus Heights homes have permit history split between Sacramento County Archives and the City. Missing paperwork stalls inspection sign-off and triggers a change order for documentation. We chase both systems before we apply.
Pricing for Home Additions & ADU in Citrus Heights, CA
Here’s the honest Citrus Heights market for the work we do most.
| Project | Citrus Heights Price Range |
|---|---|
| Home Addition | $45,000-$130,000 |
| ADU Construction | $90,000-$220,000 |
| Garage Conversion | $30,000-$80,000 |
A $90,000 ADU in Citrus Heights is typically an interior or garage conversion with a straightforward panel upgrade and no septic fight. A $220,000 ADU is a detached unit on an acre lot with county setbacks, a directional bore for power, a 200-amp service upgrade, and engineered footings for expansive clay. The gap between those numbers is site work, not markup. Call (877) 610-1318 and we’ll walk your lot and put the real number on paper.

FAQs - Home Additions & ADU in Citrus Heights
A pre-1997 Citrus Heights home adds roughly two to four weeks to the permit process because records are split between Sacramento County Archives and the City of Citrus Heights. We do the records chase before we submit drawings, so the timeline hit happens before you’ve paid for materials, not while the crew is standing in your yard. Call (877) 610-1318 and we’ll pull your record first.
Citrus Heights sits on Sacramento Valley expansive clay that swells in winter and shrinks in summer, and most 1950s-1970s tracts here were slabbed without engineered soil prep. Roseville’s newer subdivisions were graded and compacted to modern standards, so they don’t move the same way. We dig deeper footings and test compaction before tying anything to an existing Citrus Heights slab. It’s not optional. It’s the difference between a straight seam and a shear crack in two winters.
Usually yes, but county septic and well setbacks will dictate where it can sit, and those clearances can shrink your usable build area by 20% or more. We map the leach field and the well radius before we draw the footprint. The 480-square-foot ADU we scoped off Greenback Lane had to shift 30 feet past the existing leach field because of that exact setback. Call (877) 610-1318 and we’ll map your lot.
The gap is almost always site work: septic and well setbacks, a directional bore for electrical service, a 200-amp panel upgrade, clay-soil footings, and the pre-1997 permit records chase. A garage conversion with an easy panel tie-in lands near the bottom of the range. A detached unit on an acre lot with no existing utilities nearby lands near the top. We itemize every one of those costs in a written change order before work starts, so you see the number before you commit to it.
Because a 1960s Citrus Heights tract home was wired for a 100-amp life: lights, a range, and a window AC. Add a mini-split, a kitchenette, and a water heater for an ADU, and you’ll trip the main on the first hot August afternoon. We check the panel before we quote so the service upgrade is in the number you sign, not a surprise change order after demo day.
