AfterFast, Reliable Home Additions & ADU Across Homeland
A room addition in Homeland typically runs $45,000 to $130,000, and a full detached ADU usually lands between $90,000 and $220,000. That’s the honest range before we ever step foot on your property. Call (877) 610-1318 for a free estimate and we’ll give you exact numbers in writing, not a guess over the phone.
Homeland homeowners call us because we understand what this valley does to a foundation. The adobe clay swells with winter rain and shrinks hard in summer heat. That cycle has cracked slabs and shifted walls on plenty of lots across the 92548 corridor. We plan for it from the first shovel of dirt. One call gets Tom Barrett or one of his sons on the line, and we’ll schedule a site visit that fits your week, not ours.
Why Barrett & Sons Construction Is Homeland’s Preferred Home Additions & ADU Company
We’ve been building in Riverside County for over 29 years, and the work we do in Homeland goes through the same hands as every other Barrett & Sons job. Tom Barrett owns the company. His sons run the crews. That means the person who shakes your hand is the same person you’ll see at the lumberyard on Saturday and the same person standing in your yard when the inspector walks the site. This isn’t a franchise dispatching strangers from two counties away.
Homeland’s unincorporated status adds a layer of process that out-of-area contractors routinely underestimate. Every permit here runs through Homeland‘s county jurisdiction: Riverside County Building and Safety. We file there constantly. We know which counter handles what, which inspector covers which district, and how to keep a project moving without burning your time. When a Homeland customer calls with a question about their addition or ADU, they get a live person on the phone. Not a voicemail box. Not a call center.
We also know the dirt. The caliche layer under many Homeland parcels has surprised more than one excavator, and it’s the kind of thing that turns a clean footing dig into a week of delays if nobody probed for it first. We probe. It’s a $200 precaution that saves thousands in rework, and it’s standard practice on every addition and ADU we build in this valley.
Our Home Additions & ADU Services in Homeland
ADU Design & Permitting
A detached ADU in Homeland starts with the county, not just a set of plans. Riverside County Building and Safety reviews every ADU submittal, and the process goes smoother when the drawings already reflect county rural/residential standards: setbacks, fire-rated assemblies for Santa Ana wind zones, and engineered footings for expansive soil. We handle the design, the submittal, the corrections, and the inspections. You handle the decisions. A typical ADU design and permitting package in Homeland runs $8,000 to $15,000 before construction begins, depending on site complexity and utility runs.
Garage Conversion ADU
A garage conversion ADU in Homeland runs $30,000 to $80,000, and it’s often the fastest path to a rentable unit on a lot that already has a pad and framing. The catch here is the slab. Many Homeland garages sit on thin, unreinforced concrete poured decades ago, before anyone thought about adobe clay movement. We don’t just frame walls on a cracked garage floor. We check the slab, assess drainage, and bring the foundation up to county standard before we close in the walls. On a job near the master-planned streets off the 92548 corridor, we saw a garage slab that had heaved nearly two inches at one corner. Engineered footings solved it. The county signed off on the first pass.
New Detached ADU
A new detached ADU in Homeland typically runs $90,000 to $220,000, built from the ground up. That includes engineered footings below the caliche line, drainage plane work, and utility trenching sized for ADU loads. On larger rural lots with septic and well systems, we coordinate with Riverside County Environmental Health for any sewer or water upgrades the ADU triggers. On tighter master-planned lots with HOA overlays, we pull the architectural review package before we pull the building permit. Both paths cost less when the sequence is right, and we get the sequence right every time.
Junior ADU & Interior Conversion
A Junior ADU or interior conversion turns existing square footage into a small living unit, and it’s one of the areas where Homeland homeowners get burned most often. Cutting into a load-bearing wall on a newer home can void the builder warranty if it isn’t done under a structural engineer’s written direction and a county permit. We bring both. Every JADU and interior conversion we do in Homeland includes the structural engineer’s letter, the permit, and the inspection. We don’t do unpermitted work, and we don’t let the builder warranty slip away over a shortcut.

Our Home Additions & ADU Team in Homeland
When we build a room addition or ADU in Homeland, the crew on your property answers to Tom Barrett and his sons. The same family has run the job site since 1998. You’ll see the same faces day to day - background-checked, uniformed, and carrying the Barrett & Sons name. We don’t hand your project to a rotating cast of subcontractors. Our Home Additions & ADU team handles the structural work, the framing, the rough-in, and the finish. Trade-specific work like electrical and plumbing goes to licensed crews we’ve used for years and who know the Riverside County inspection process. Every price change is a written change order before work proceeds. Every permit is pulled. Every inspection is signed before we call the job done.
Trusted Brands We Service in Homeland
We install materials you can look up, because that’s what a homeowner with a job this size deserves. For hardscape work tied to ADU site prep and patio additions, we carry Belgard and Techo-Bloc paver lines. For concrete driveways and slabs, we use Quikrete products selected for the Inland Empire’s soil conditions. We don’t load mystery brands off a van. If a paver cracks or a finish fails, you know exactly what was installed and we’re back under the 90-Day Done Right Promise to make it right. Every contract carries that promise in writing, not buried in fine print.
Common Home Additions & ADU Problems We See in Homeland Homes
- Footings poured without probing for caliche. The hardpan under many Homeland parcels looks like solid ground until drainage ponds against the new slab after the first winter rain. We probe every excavation before we pour. It’s cheap insurance against a cracked foundation.
- HOA architectural rules missed before the plans are drawn. Several Homeland master-planned developments have setback requirements and design standards that differ from county code. We pull the HOA review early, so the county inspector doesn’t flag an unapproved setback and stop work mid-framing.
- Builder warranties voided by unpermitted structural cuts. We see this on newer homes where someone tried to convert a garage or add a Junior ADU by cutting into a load-bearing wall without an engineer’s letter. The county catches it, the builder voids the warranty, and the homeowner pays twice. We don’t let that happen.
- Drainage planes omitted on adobe clay lots. Adobe soil swells and shrinks with the seasons. A slab with no drainage plane below the caliche line will move. We build the drainage into the foundation, not as an afterthought on top of it.

Homeland’s Housing Stock and What It Means for Your Addition
Homeland is a mix of mid-century site-built homes, a good number of manufactured and mobile housing units on permanent pads, and scattered rural outbuildings on larger lots. That matters for additions and ADUs because the foundation condition underneath varies wildly from lot to lot. A 1960s ranch home off a graded county road sits on a different slab than a 1990s manufactured home set on piers. We’ve worked both. The mid-century homes often have sound framing but undersized footings for an addition. The manufactured homes need engineered tie-downs and county approval before any attached conversion. The rural lots with septic and wells trigger Environmental Health review when an ADU gets added. We handle all of it, and we tell you which path your property needs before you spend a dollar on plans.

FAQs - Home Additions & ADU in Homeland
Do ADU permits in Homeland go through a city office, or Riverside County?
All ADU permits in Homeland go through Riverside County Building and Safety, because Homeland is unincorporated and has no city building department. We file with the county on every ADU and addition, and we know the process well enough to avoid the common delays that come from incomplete submittals. Call (877) 610-1318 if you want to talk through your specific lot before you file anything.
How does the caliche layer on my Homeland lot affect an ADU foundation?
The caliche hardpan beneath many Homeland parcels can stop a standard footing excavation dead, and it often causes drainage to pond against foundations after winter rains. We probe for caliche before we dig, and we design footings that sit below the hardpan with a drainage plane that moves water away from the slab. Skipping this step is how ADU foundations fail in this valley. We never skip it.
Can I convert my attached garage to an ADU without voiding my builder warranty?
Not if you cut into a load-bearing wall without a structural engineer’s written direction and a county permit. That’s the fastest way to void a builder warranty on a newer Homeland home. We handle garage conversions with the engineer’s letter, the permit, and the inspection all in place, so the warranty stays intact and the county signs off without a stop-work order.
What HOA or architectural rules apply to a detached ADU in a Homeland master-planned community?
Several Homeland master-planned developments have setback requirements, height limits, and design standards that go beyond county code. We pull the HOA architectural review package before we submit the county permit, so you don’t end up with an unapproved setback that halts the job after framing starts.
Why do room additions in Homeland need more than a standard concrete slab?
Because the adobe clay under this valley swells with winter rain and shrinks with summer heat, a standard slab without engineered footings and a drainage plane will crack and shift. We build every room addition in Homeland with footings below the caliche line and a drainage design sized for the soil cycle. Call (877) 610-1318 for a free estimate and we’ll show you exactly what your lot needs.
What neighborhoods and areas across Homeland do you cover?
We cover all of Homeland, including the 92548 ZIP corridor and the surrounding master-planned streets, the rural lots with septic and well systems, and the manufactured housing communities on permanent pads. If you’re in Homeland, we’re close by.
