We’re Lodgewick ADU Riverside, the ADU company of the Kingswell family. In Home Gardens, most ADU work happens on single-story ranch homes built between the 1950s and 1970s, sitting on lots of 7,200 square feet or more. That older housing stock, combined with the unincorporated Riverside County permit process and the fact that many properties here run on septic rather than sewer, means an ADU project in Home Gardens moves differently than it does in Corona or Riverside proper. We work with that reality every week, and we put every commitment in writing before the first nail goes in. Call us at (831) 292-4191 to talk through your lot.
Why Home Gardens Homes Are Different
Home Gardens sits in an unincorporated pocket of Riverside County, and that fact alone changes how ADU projects unfold. There is no city building department here; permits go through the County, which tends to be slower and more paperwork-heavy than what homeowners in incorporated cities experience. We plan for that on the front end so it doesn’t blindside you mid-project. The housing stock is almost entirely ranch and stucco tract homes from the 1950s through the 1970s, often with detached garages set back from the house. That layout actually works well for detached ADUs, especially on lots that run 7,000 to 10,000 square feet, because there’s room to build without crowding the main house. Many neighborhoods in Home Gardens are still on septic systems rather than sewer lines, which means an ADU here can require a percolation test and sometimes a septic tank upgrade before construction can begin. We’ve worked through that hurdle enough times to know what it does to the timeline and the budget. The inland climate also shapes the work: summer highs regularly push past 95°F, so we spec high-efficiency HVAC and cool-roof materials as standard on ADUs here. Mild winters mean we don’t have to overbuild insulation the way you would in colder regions, which keeps cost per square foot reasonable without sacrificing comfort.
Our Main Home Gardens Services
Home Gardens homeowners most often call us about two things: adding a detached unit on the back of a large lot, and converting an existing detached garage into livable space. Here’s how each works here.
Home Addition Contractor in Home Gardens
A home addition in Home Gardens means working with the same ranch-lot realities as an ADU, but attached to the main structure. Septic capacity questions still apply, and the County permit path is the same. What changes is the structural tie-in: older stucco homes from this era weren’t always built to the same framing standards we use today, so we spend real time on the connection point between old and new. We handle that carefully, with written engineering before work starts. Learn more about what a Home Addition Contractor in Home Gardens should deliver before you sign anything.
Garage Conversion Contractor in Home Gardens
Detached garages are common on Home Gardens lots, and converting one into an ADU (an accessory dwelling unit, a secondary home on your property) is often the fastest path to rental income or a place for family. The catch here is that older garages weren’t poured as living space: the slab may be too thin, the electrical panel too small, and the roofline too low. Septic constraints can also limit how many bedrooms a converted garage can legally have. We walk each job with those specifics in hand. See what a Garage Conversion Contractor in Home Gardens should include in the written quote.
ADU Builders in Home Gardens
A detached ADU is a stand-alone small house, and on the wide lots of Home Gardens it’s often the smartest use of the space. The County’s septic rules and percolation requirements mean not every lot can support the same square footage, so we size the unit to what the land will actually allow. We build both stick-frame and prefab units here, depending on access, slope, and the homeowner’s timeline. Prefab options like Abodu and Cover can shorten on-site construction significantly, which matters when the County process has already taken weeks.

Brands We Service in Home Gardens
We work regularly with our brands that include Abodu, Cover, and Mighty Buildings. These prefab manufacturers give Home Gardens homeowners a faster path to a finished unit when the County permit process has already consumed part of the timeline. Sizing and lot access are the two things that usually determine which system fits best, and we’ll walk you through that in plain language before you commit to anything.

Two things push prices on Home Gardens projects above what you’d see in a sewer-connected city. The first is septic: if your tank can’t handle the added load, you’re looking at an upgrade before the ADU itself can be permitted. The second is the County permit timeline, which can extend soft costs on anything that requires multiple plan revisions. Whatever the number ends up being, you’ll see it in writing before any work starts – that’s The Kingswell Way, and it doesn’t change once the job begins.

FAQs About ADU Company in Home Gardens
Plan for four to eight months from submittal to approved permit for a typical ADU in Home Gardens. The unincorporated County process runs slower than city permitting, especially if septic review triggers additional plan checks. We handle the submittal and resubmittals for you, and we’ll tell you upfront if your lot’s septic status is likely to add time. Call (831) 292-4191 and we’ll give you an honest read on your specific property.
It depends on your tank size, the number of bedrooms in the ADU, and the results of a percolation test. Some lots pass with no changes; others need a larger tank or a replacement leach field. We don’t guess – we test first, then give you the written number. Estimates are free, and the test cost is a line item you’ll see before we proceed.
Yes, we build on septic lots regularly. The ADU just has to be sized and placed to work with what the soil and the tank will support. That’s a planning conversation we have early, because it affects the unit’s square footage and where it can sit on the lot. Call us at (831) 292-4191 and we’ll walk your property with that question in mind from the first visit.

What Home Gardens Customers Say
"Quality work on a home addition. It did run a few weeks longer than the original estimate, mostly waiting on the city for inspections, which they explained. The build itself was done right."
- Marcus Delgado"Garage conversion into a studio for our teenager. Honest about what was realistic and what wasn't, finished close to schedule, and cleaned up the site daily."
- Marcus Beaumont"Garage conversion into an office and guest room. Fair written price, finished close to on schedule, and they fixed a small drywall crack under warranty months later without any hassle."
