Frequently Asked Questions

A typical detached ADU in Riverside takes 7 to 11 months from initial design to final inspection, and a garage conversion usually takes 4 to 6 months. The largest variables are plan check at the city and your site's condition. Riverside's planning and building departments have improved turnaround in recent years, but plan review can still take 10 to 16 weeks depending on workload and whether your design triggers design review. Construction itself is often faster than people expect once permits are issued. We'll give you a realistic schedule with your written quote.

The first step is a property-specific feasibility check: we look at your lot size, setbacks, existing utilities, and zoning to confirm an ADU is allowed and what size makes sense. That's free. We're not selling a stock plan that might not fit; we're checking your actual parcel against Riverside's ADU ordinance and the state's ADU mandates. If the lot works, we move into design and a written price for the full job. Call (831) 292-4191 and we'll walk the property with you.

Yes, we pull the permits, submit the plans, schedule the inspections, and coordinate with Riverside's building department from the first submittal through final sign-off. We don't hand you a set of drawings and wish you luck. The Kingswell Way means the price is in writing before any work starts, so there's no point in the process where you're surprised by a permit fee or inspection requirement. If the city asks for revisions, we handle the revisions. You get a unit that's permitted and inspection-passed, which matters when you sell or refinance.

Yes, hillside lots in neighborhoods like Alessandro Heights and Canyon Crest can absolutely support ADUs, but they typically require more site work and structural engineering than flat parcels. You'll likely need a geotechnical report for the foundation, and the structure may need deeper footings or retaining walls. That's where the per-square-foot cost climbs. We've built on sloped sites all over Riverside and will tell you honestly if your hillside plot makes better sense for a garage conversion than a full ground-up build. The feasibility check is free.

You can rent the ADU as soon as you receive your certificate of occupancy from the city, which we obtain as part of the final inspection process. Riverside allows long-term rentals of ADUs, and the added rental income is one of the main reasons homeowners build them. Some owners move into the ADU themselves and rent the main house instead. Riverside's rental market for one-bedroom units is strong given the demand near UCR and downtown, though we're builders, not property managers, so we'll point you to local professionals for leasing questions. The build itself is our job.

Yes, our team works throughout the Inland Empire, including Ontario, Fontana, Chino, Rialto, Upland, Montclair, Highland, Beaumont, Wildomar, Temescal Valley, and El Cerrito. Each city has its own plan check rhythm and local interpretations of the state ADU mandates, so it helps to have a team that's already navigated them. Ontario's newer tract lots often need less site work than Riverside's older neighborhoods, while Fontana's hillside developments can be steeper. Same written-price structure, same Kingswell Guarantee, whichever city you're in.

We've installed and finished units from several factory-built systems, including Abodu, Dvele, and Cover, and we're happy to discuss which one fits your site and budget. Prefab can speed up the construction phase considerably once the site work and foundation are done, though the planning and permit phase stays roughly the same as a stick-built unit. Some Riverside homeowners prefer a panelized shell with local finishing, and others want full site-built framing with materials like James Hardie siding. We'll show you the tradeoffs in writing.

The difference is where the structure is assembled: a prefab or panelized ADU is built in a factory and delivered to your lot, while a site-built ADU is framed, sheathed, and finished entirely on site. Prefab from companies like Abodu or Cover can cut construction time meaningfully, but you still need the same foundation, utility connections, and inspections. Site-built framing gives more flexibility for irregular Riverside lots and custom window placement. Cost is often comparable once you add delivery and crane time. We'll walk through both options with you before you commit.

We do recommend James Hardie siding for many Riverside ADUs because it handles the Inland Empire's dry heat and UV exposure well and holds paint longer than wood. Riverside summers in neighborhoods like Orangecrest and Mission Grove are brutal on cedar, and Hardie plank doesn't warp or fade the same way. It's not the cheapest siding option, which is why we give you a line-item choice rather than defaulting to it on every quote. Stucco remains very common in Riverside and is also a solid choice. The right call depends on the style of your main house and what the neighborhood expects.

Yes. Every professional working under our name is required to hold the license and insurance their state requires for the work they perform, and our Riverside branch operates to the same Kingswell standards as every other Lodgewick location. We pull permits on every job, which means the city's inspectors review our work at multiple stages. If a license number or insurance certificate is important to you, ask us for a copy before you sign. We'd rather show you than tell you. Call (831) 292-4191 with any credential questions.

Lodgewick ADU Riverside is a local branch of Lodgewick ADU Builders, which is part of the Kingswell family of home-service brands. Each location is independently owned and operated, which means this Riverside team is local: we know the neighborhoods, the soil conditions, the plan check quirks at the city, and the local inspectors. What ties every branch together is the same four promises: a written price before work starts, a real arrival window, a clean job site, and a written guarantee on the work. Russ Delmar leads our team here in Riverside.

Yes, anyone building an ADU in Riverside for you should hold a California general contractor's license, and subs like electricians and plumbers need their own state licenses. Working with an unlicensed builder on a $200,000 project is a risk you don't want to take, and unpermitted work can create a mess when you try to sell or refinance. We're required to hold the proper licensing, and the city verifies that when we pull permits. If a quote seems too cheap, check the license before you check your wallet.

An ADU is a long-term solution, not a fast response, but it's often built exactly because a family situation changed: an aging parent needs to live closer, or an adult child needs a place while life sorts itself out. The build still takes months once permits are through. What we can do quickly is the first step: visiting your Riverside property and telling you honestly what's possible. If you're facing an urgent housing need, a permitted ADU is built for exactly that purpose over the long run. Call (831) 292-4191 and we'll start with the free feasibility check.

Our Riverside team answers calls Monday through Friday from 7:00 AM to 7:00 PM, and Sunday from 7:00 AM to 7:00 PM. We're closed on Saturdays. When you call (831) 292-4191, a live coordinator answers and connects you with our local team to talk through your project. We schedule site visits during the week, and we keep the process simple: the first conversation is about your lot and your goals, not a sales pitch. A lodge is a small house on a larger property, which is exactly what an ADU is, and that's what we build.

If something fails inside the guarantee period, we come back and fix it at no charge. That's the Kingswell Guarantee in writing, and it covers the work we performed for you. The guarantee period is stated plainly in your contract before you sign, so you know what's covered and for how long. We've seen too many Riverside homeowners get burned by builders who disappear after final inspection, which is why the guarantee is written, not verbal. That's the point of The Kingswell Way: put the guarantee in writing and come back if it fails.

Our written guarantee covers our workmanship for the period stated in your contract, and if a repair fails inside that period, we come back and fix it at no charge. That includes things like framing, drywall, finish carpentry, and the systems we installed. Manufacturer warranties run separately: your appliances, windows, and exterior finishes like James Hardie siding carry their own product warranties, and we'll organize those documents for you at closeout. The guarantee is the same four promises every Kingswell company works to, and they're in your contract before any work starts.

Yes, the guarantee is in your written contract before any work starts, not in a verbal promise or a handshake. Every Kingswell company works to the same four promises: a written price before any work starts, a real arrival window, a clean job site, and a written guarantee on the work. We want you to read it before you sign anything. Russ Delmar and our Riverside team stand behind the work, and the guarantee is the point: room to grow, right on your lot, with a company that comes back if it fails.

It means the written price is in your contract before we start, and that price is line-itemed so you can see what's going into it: site work, foundation, framing, finishes, permits, utilities, and everything else. The point is no change orders after the fact, and no surprise at the end. If the city requires an unexpected upgrade, we tell you before we do it, not after. Riverside homeowners tell us the fear of a price changing at the door is a big reason they hesitate, and the fix for that is simple: we say the price before the work, in writing. Call (831) 292-4191 for a free estimate on your lot.

The price should not change if the scope doesn't change, and our written quote states the scope plainly. What can change the price mid-project is the same thing that changes it on any Riverside construction job: the city requiring something extra, a hidden condition under the slab, or you choosing a different finish than originally specified. When that happens, we tell you before any extra work is performed, and you approve the change in writing. You never get a surprise line item after the fact. That's the difference between a written price and an estimate in the wind.
