General information only — not legal, tax or financial advice. Timelines and costs vary with scope, site conditions and city processing.
Everything needed to complete the home: full construction cost, construction management, interior design, and landscape architecture. On projects that already have ready-to-issue plans, the price also covers demolition, permit fees, new utility fees, and other city-related costs. Projects still in pre-RTI stages carry additional cost for architecture, permitting, and preliminary planning. No hidden costs, no surprises later.
It depends on the site. Once plans are ready to issue, flat lots with minimal or no caisson requirements typically complete in 8–12 months. Hillside properties requiring moderate to major caisson and retaining wall work run 12–24 months. If you don't have RTI plans yet, we can recommend architects and help you secure approvals. All timelines are estimates, not guarantees — actual schedules vary with project scope, site conditions, city processing times, and timely client funding and decisions.
TDG doesn't lend directly, but we'll connect you with our network of preferred lenders who specialize in construction financing — whether you're funding a full redevelopment or a ground-up build.
We build in Los Angeles and select adjacent markets — Malibu, Pasadena, Orange County, and the South Bay — plus a significant focus on the communities affected by the Palisades and Eaton fires. We stay in these areas because we know the restrictions, codes, and ordinances in each jurisdiction, which is what keeps our timelines and budgets honest.
Both, though most of our ADUs are designed as part of a larger development. We take on select standalone ADU projects where the site and scope make sense. Send us the address and we’ll tell you either way.
There is no honest per-square-foot answer, which is why we don’t publish one. Attached versus detached, how far utilities have to run, slope and soils, and whether it is new construction or a conversion all move the number before finish level is even discussed — see what drives cost above. We give a written estimate after reviewing the property.
Yes. Every ADU requires permits, and hillside parcels frequently require more of them. California has made ADUs meaningfully easier to permit than they once were, but easier is not the same as exempt. We handle design, permitting and construction in-house, so there is one point of accountability rather than a designer, an expediter and a builder pointing at each other.
It depends on lot size, setbacks, topography, and what you want the space to do. On larger hillside parcels a detached structure usually places better; on tighter flat lots an attached unit often makes more sense. That determination is part of the feasibility assessment.
No. We buy as-is, in current condition. That includes deferred maintenance, dated systems, foundation issues, unpermitted work, and properties that wouldn’t pass a conventional inspection. You don’t need to paint, stage, clear the property, or make repairs.
Not to us. Selling directly to TDG means no listing commission and no staging or preparation costs. Standard closing costs and your own advisors are the usual exceptions — we’ll lay out exactly what applies before you sign anything.
Fast when you need it, and slower when you don’t. Some sellers want a quick, certain exit; others need months to find their next place. We build the closing date around your situation rather than ours.
We underwrite the land and what can be built on it — zoning, lot size, neighborhood comps for finished product, and the cost and time to get there. We’ll walk you through the reasoning rather than just handing you a number.
Reach out as early as you can. We'll set up a meeting to assess the site and talk through what you want the rebuild to be — whether that's restoring what was there or building something new. From that we put together a redevelopment plan matched to your goals and budget. We can also connect you with resources for navigating insurance claims and introduce you to architects who design well for these sites.
Once plans are ready to issue, flat lots with minimal caisson work typically complete in 8–12 months. Hillside sites needing significant caisson and retaining wall work run 12–24 months. If you don't have RTI plans yet, we can recommend architects and help you through the approvals. The permit path itself differs by jurisdiction — see our LA fire rebuild permit tracker for the City and County programs.
It depends on your insurance settlement, your timeline, and what the lot can support. We'll run both numbers honestly — what a rebuild would cost and deliver, versus what we'd pay for the lot outright. If selling is the better answer for you, we'll say so.
TDG doesn't lend directly, but we'll connect you with lenders in our network who specialize in construction financing and understand rebuild timelines.
No. This warranty program applies to ground-up new construction homes only, under California’s SB-800 statute. TDG does not provide the Builder Warranty, or any equivalent warranty, on remodeled homes — remodel workmanship is governed by the applicable construction contract. Buyers should confirm whether a given home is new construction or a remodel as part of their due diligence.
All coverage periods begin on the date the new construction property receives its Certificate of Occupancy.
Contact us directly and our customer experience team will walk you through the applicable SB-800 claim process for your home.
SB-800 rights attach to the residence for the applicable statutory periods. Terms vary by situation — consult a TDG representative and your own counsel for specifics on your property.
