Adding square footage to your home in Citrus means dealing with real constraints: lot coverage limits, setbacks, hillside grading, and a plan-check process that rewards preparation and punishes guesswork. We’ve framed additions on Citrus Avenue, worked around foothill-adjacent lots near the San Gabriel Valley transition, and pulled permits through the City of Citrus enough times to know exactly what slows a project down and what keeps it moving. If you’re planning a room addition, second story, sunroom, or bump-out, call (903) 568-7222 and we’ll walk the site, review your survey, and put a written price in front of you before any work starts.
Why Benson ADU Builders Is Citrus’s Preferred Home Addition Contractor Team

We don’t hand you a verbal ballpark and disappear until demo day. Every Citrus project starts with a written scope and a line-item price, so you know what the permit fees, structural upgrades, framing, and finishes will cost before you sign anything. That’s the Relay Visibility Guarantee, and it’s stamped on every project we take on in Citrus.
Homeowners in Citrus keep flagging the same three things when they call us: they want a contractor who answers the phone, they want a price that doesn’t drift, and they want to know who’s showing up at their front door. Our crews are background-checked, uniformed, and dispatched with live arrival updates. A real person answers our line 24/7, which matters when you’re coordinating a second-story addition around a family living in the house below it.
Troy Eastman leads our team and signs off on every Citrus scope before it goes to you. The 365-Day Done Right Promise backs the workmanship: if something isn’t right within a full year, we make it right. In writing, on every project.
Sunroom Addition in Citrus
A sunroom addition in Citrus runs roughly $28,000 to $72,000 depending on whether you’re doing a prefab panel system, a site-built space with a poured slab, or a conditioned room with HVAC tie-in. The first question is whether the sunroom will be permitted as living space or as a non-habitable enclosed patio, because that decision changes the foundation depth, glazing requirements, and plan-check path with the City of Citrus. On Citrus Avenue and the streets branching toward the foothills, we see a lot of ranch homes where a south-facing sunroom makes sense, but the lot’s rear setback often pushes the room narrower than the homeowner assumed from a rough sketch.
Foundation and Glazing Choices
A permitted living-space sunroom needs a foundation that meets Citrus’s frost and soil requirements, plus glazing that meets Title 24 energy rules. A non-habitable patio enclosure has looser requirements but can’t legally be marketed as a bedroom or family room later. We’ll flag the difference before you commit.
Permitting a Sunroom in Citrus
The City of Citrus plan-check group reviews sunroom additions for setback compliance, lot-coverage math, and energy code. That’s not a rubber stamp. Expect two to six weeks of plan-check time depending on current volume, and we handle the submittal, resubmittal, and inspection scheduling so you don’t chase the counter.
Second Story Addition Contractor in Citrus

A second story addition contractor in Citrus has to answer the hardest engineering question first: can the existing first-floor walls and foundation carry the new load? On older Citrus ranches, the answer is usually no without a structural upgrade. You’re looking at $180 to $340 per square foot for a second-story addition in Citrus once you factor in structural reinforcement, stair placement, re-roofing the existing footprint, and the lateral bracing the City of Citrus requires in this foothill-adjacent seismic zone.
Structural Upgrades Underneath the New Floor
Most single-story Citrus homes were built before current lateral-load standards. Adding a second floor means bolts, hold-downs, shear panels, and often a foundation enlargement under the existing footprint. Budgeting only for framing and drywall misses the biggest line item. We scope the structural work in the written price, not as a discovery later.
Matching the Existing Street Face
On a Citrus Avenue lot near the foothill edge, our crew framed a second-story addition over an existing single-story ranch and tied it into the original roof line while matching the existing stucco and fascia. We coordinated the structural upgrade and inspection sequence with the city so the new upper floor, stair, and window layout stayed inside the lot-coverage and setback limits. The homeowners got the extra bedroom and bath they wanted without changing the street-facing massing.
Trusted Brands We Service in Citrus
We’re authorized to build with prefab and cladding brands Citrus homeowners can research independently before they ever call us. That includes Abodu and Cover for panelized ADU and addition systems, Dvele for high-performance prefab builds, and James Hardie siding and trim for exterior finishes that hold up to San Gabriel Valley sun and dry heat. Because we stock and source these systems directly, we can give you a real availability window instead of a hand-wave. If you’d rather site-build the whole thing, we do that too, with the same written price upfront.
Common Home Addition Contractor Problems We See in Citrus Homes
- Scoping off a rough sketch instead of a site survey. We see Citrus projects stall at plan check because the lot’s actual setbacks, lot coverage, or hillside grading constraints push the design back through review. A survey before the first drawing saves weeks and thousands.
- Budgeting only for framing and finishes. An older Citrus home usually needs foundation, structural, and lateral upgrades before it can carry a second story or a new room. Builders who leave those out of the quote “discover” them later. We put them in the written price from day one.
- Forgetting the City of Citrus permit, plan-check, and inspection fees. These are not optional, and they’re not hidden. On a typical Citrus addition, city fees run $3,000 to $9,000 depending on project size and plan-check cycles. We itemize them.
- Assuming the contractor’s first number is the final number. In Citrus, the three real change-order triggers are: a design change once framing starts, an unanticipated structural condition behind the stucco, and a plan-check correction that expands the scope. We write the change-order process into the contract, and we don’t bill for our own scope mistakes.

FAQs About Home Addition Contractor in Citrus
Yes, on most Citrus homes built before current lateral-load codes, a second-story addition requires structural upgrades to the existing first-floor walls, foundation, and connections. Expect bolts, hold-downs, shear panels, and often foundation enlargement. We scope this in the written price before work starts, so it’s not a surprise line item. Call (903) 568-7222 for an exact assessment of your house.
Plan check with the City of Citrus typically adds two to six weeks to an addition timeline, depending on current volume and whether the first submittal is complete. Resubmittals add another cycle. We handle the submittal, corrections, and inspection scheduling so you’re not chasing the counter. The written price includes an estimate of city fees so you know the true project cost up front.
Three things move the number on an active Citrus addition: a design change after framing starts, an unanticipated structural condition hidden in the existing walls or foundation, and a plan-check correction that expands the scope. We write the change-order process into the contract and don’t bill for our own scope mistakes. You approve any change in writing before the work continues.
Yes, a sunroom in Citrus can be permitted as living space if it meets the City of Citrus requirements for foundation depth, glazing, energy compliance, and means of egress. It can also be permitted as a non-habitable patio enclosure, which is less expensive but can’t be marketed as a bedroom or family room later. We’ll walk you through both paths before you commit.
A ground-floor addition in Citrus typically takes five to eight months from first site visit to final inspection. A second-story addition runs seven to twelve months, and a sunroom runs three to five months. The biggest variables are plan-check cycles with the City of Citrus and the structural scope on older homes. We’ll give you a written timeline with milestones at the estimate stage.
