Pricing & Cost FAQs
An ADU in Houston typically costs between $180,000 and $380,000 depending on size, site conditions, utility connections, and finish level. A simpler one-bedroom unit on a flat lot with easy utility access sits at the lower end. A two-bedroom unit with a full kitchen, a dedicated electrical panel, and a longer sewer line run sits at the upper end. Permit fees in Houston fluctuate by scope, and foundation work on Houston's clay-heavy soils can shift pricing. Russ Delmar and the Lodgewick ADU Houston team write a fixed-price quote before any work starts, so the number you're quoted is the number you pay. Call (361) 326-2313 for a free line-item estimate on your exact lot.
The least expensive ADU is usually a garage conversion. The shell already exists, so you're paying for insulation, electrical, plumbing, drywall, and finishes rather than new framing and a new foundation. In Houston, a basic garage conversion often lands below a detached new-build ADU because you skip foundation work and some structural costs. That said, older Houston garages sometimes need slab repairs or roof work before conversion, and that can close the gap. The honest answer is that every lot is different. A written quote from the Lodgewick ADU Houston team costs nothing and gives you real numbers. Call (361) 326-2313 and we'll walk your property and price it properly.
Yes, an ADU typically increases property value in Houston, though the amount depends on the neighborhood and the quality of the build. Appraisers generally view a permitted ADU as additional livable square footage, which tends to raise assessed value. Rental income is the other piece. A one-bedroom ADU in areas like Montrose, the Heights, or near the Med Center can generate meaningful monthly rent, and that income stream often supports the construction cost over time. In suburbs like Sugar Land or Katy, an ADU can be the deciding feature for a multigenerational buyer. A properly permitted ADU built with a written warranty holds value better than unpermitted work, which can actually hurt a sale.
For most homeowners we speak with, yes. The math usually works in one of three ways: rental income that offsets the build cost over several years, aging parents moving closer without leaving the neighborhood, or adult children staying while they save for a home. The Houston market has strong rental demand near downtown, the Texas Medical Center, and the universities, which makes an ADU a practical income property. Construction costs are real, and financing needs thought, but a well-built ADU in Houston rarely sits empty. We encourage homeowners to get a fixed written price first, then run their own rent research. Call (361) 326-2313 for that written quote.
Houston homeowners typically finance ADUs through a home equity loan, a HELOC, a cash-out refinance, or a construction loan. Some banks and credit unions in the Houston area have begun offering ADU-specific loan products, though terms vary widely. Cash is the simplest path and avoids financing costs entirely. The key number for any lender is the total project cost, which is exactly why we provide a written fixed price before any work begins. That document is what lenders want to see. If financing is part of your plan, start by getting the real project number from Lodgewick ADU Houston. Call (361) 326-2313 to schedule a free estimate.
No. Lodgewick ADU Houston works to a fixed written price. Every job gets a line-item quote before any work starts, and the price on that quote is the price on the final invoice. If we find something unexpected under the slab or behind the drywall, we stop and show you exactly what changed and what it costs, before we spend a dollar on it. No change orders appear out of nowhere. That's the Kingswell Way: say the price before the work. If a Houston contractor won't put the price in writing before starting, that's a warning sign. Call (361) 326-2313 and ask us for a written quote on your ADU.
Service & Process FAQs
The process has four clear steps: site assessment, design and permitting, construction, and final inspection. First we walk your lot in Houston, check setbacks, utility locations, and soil conditions. Then we produce a plan set and submit it to the City of Houston for permit approval. Once permits clear, construction begins on a written schedule, and we show up in the window we gave. Finally, the city inspects the finished unit, and we walk through every detail with you. You get a written warranty at completion. Most Houston ADUs take several months from first call to final inspection. Call (361) 326-2313 and Russ can walk you through what a timeline looks like for your specific lot.
Most ADUs in Houston take between six and twelve months from the first site visit to final inspection, assuming no unusual permitting delays. Garage conversions typically run faster than detached new builds because the shell is already standing. Detached ADUs need foundation work, full framing, and longer utility runs, all of which add weeks or months. The City of Houston permitting department moves at its own pace, and weather delays happen, especially during hurricane season. What we promise is not speed but certainty: a written schedule, a real arrival window, and a fixed price. Call (361) 326-2313 and we'll give you a realistic timeline for your project.
Yes. Lodgewick ADU Houston pulls all required permits and manages the inspection process from first filing to final sign-off. Building an ADU in Houston without permits is a serious risk. Unpermitted work can be flagged during a future home sale, and Houston code enforcement has the authority to require removal of noncompliant structures. We don't build that way. Every ADU we build goes through the proper City of Houston permitting channels, and every inspection is passed before we call the job done. If you're comparing contractors and one suggests skipping permits, walk away. Call (361) 326-2313 and we'll show you a permitted, inspected ADU build from start to finish.
Most single-family lots in Houston can accommodate some form of ADU, but the answer depends on your lot size, setback requirements, deed restrictions, flood zone, and utility access. Houston has relatively flexible ADU rules compared to many major cities, but neighborhoods with active HOAs in places like Sugar Land, Katy, and Friendswood may add their own restrictions. Flood zone designations matter a lot in Houston, and foundation type often follows from that. The only way to know for sure is a site visit. Russ Delmar walks every lot personally before we quote. Call (361) 326-2313 to schedule yours.
Three things: written pricing, a real warranty, and proof of required licensing and insurance. Ask for a line-item written quote before any money changes hands. Ask what the warranty covers and for how long, in writing. Ask for license and insurance documentation and verify both. Then ask to see a finished ADU in person if possible. In Houston, you also want a contractor who understands our clay soil, our floodplain rules, and our hurricane-season building codes. That local knowledge prevents expensive mistakes. Every pro working under the Lodgewick name is required to hold the license and insurance their state requires, and every job gets a written guarantee. Call (361) 326-2313 before you sign with anyone.
Brands & Parts FAQs
We evaluate prefab and modular systems case by case. Some Houston lots suit factory-built components well, especially when site access is tight or the homeowner wants a faster shell. Boxabl and similar prefab systems can work for certain projects, but every system has structural and utility constraints that need checking against Houston's wind load requirements and foundation conditions. Prefab is not automatically cheaper or faster once site work, permits, and utility connections are counted. We're happy to discuss whether a prefab approach fits your lot, alongside traditional stick-built options. Call (361) 326-2313 and we'll compare both paths honestly, with real numbers.
Stick-built means the structure is framed on site, piece by piece. Prefab means large portions are built in a factory and delivered to your Houston lot for assembly. Stick-built offers more design flexibility and easier modification during construction. Prefab can reduce on-site framing time, though total project time often evens out once permits, foundation, and utilities are counted. Prefab delivery also requires a lot wide enough for truck access, which isn't always possible in older Houston neighborhoods with mature trees and narrow driveways. Both approaches can produce a quality ADU. The right choice depends on your lot and your priorities. Call (361) 326-2313 and we'll help you decide with straight information.
We have worked with homeowners interested in Mighty Buildings and Plant Prefab, and we evaluate each manufacturer's product against the specific conditions of the Houston lot. The brand matters less than the build quality, the warranty behind the product, and whether the system meets Houston code. Factory-built ADUs from reputable manufacturers can be excellent, but the site work around them is just as important as the module itself. Foundation, utilities, and finishes are where quality shows or disappears. We'll tell you plainly if a particular brand makes sense for your project or if stick-built is the better value. Call (361) 326-2313 for a straight assessment.
Houston demands materials that handle heat, humidity, and hurricane-season winds. We favor fiber-cement siding over wood where budget allows because it resists rot and termites, both constant threats in the Houston area. Metal roofing performs well in high winds and reflects heat. Proper attic ventilation and a high-quality moisture barrier matter more in Houston than almost any other market because humidity is relentless. Every window and door should be rated for this climate zone, and foundations must account for clay soil movement. We select materials based on decades of seeing what survives here. Call (361) 326-2313 and we'll show you what we use and why.
Licensing & Insurance FAQs
Every pro working under our name is required to hold the license and insurance their state requires, and Lodgewick ADU Houston carries coverage appropriate for residential construction. Before any work begins, we can provide documentation for your review. Insurance matters for two reasons: it protects your property during construction, and it confirms the contractor operates above board. In Houston, fly-by-night operators without proper coverage are common, and a homeowner who hires one assumes real financial risk. We welcome the question. Ask for our paperwork when you call (361) 326-2313, and we'll show it to you before you commit to anything.
Texas does not have a statewide general contractor license, but Houston requires permits for ADU construction, and specific trades like electrical and plumbing require state licensing. Every electrical or plumbing pro on our jobs holds the required Texas license. The city inspects the work at multiple stages, and final approval only comes when everything passes. A contractor who suggests working without permits is asking you to take a risk that can surface years later during a home sale. We don't work that way. Lodgewick ADU Houston pulls every required permit and passes every inspection before we call the job complete. Call (361) 326-2313 with any licensing questions.
We hold everyone who works on a Lodgewick ADU Houston project to the same standard: required license, required insurance, and work quality we stand behind in writing. If a specialty trade is needed on your job, they work under our supervision and our standards apply to their work. The Kingswell Guarantee covers the finished ADU regardless of which trade performed which piece. That's the point of the guarantee: you don't need to track who did what. You have one company to call if anything fails. Call (361) 326-2313 and ask us anything about how we build and who builds with us.
Emergency & Response FAQs
First, make sure everyone is safe and the structure isn't in immediate danger of further damage. If there's active flooding, stay out of the space and cut power to the unit at the breaker if you can do so safely. Then document everything with photos before any cleanup begins. Contact your homeowners insurance provider and start a claim. For structural damage, water intrusion, or roof issues, call Lodgewick ADU Houston at (361) 326-2313. We're available Monday through Friday from 7:00 AM to 7:00 PM and Sunday from 7:00 AM to 7:00 PM. We can assess the damage and give you a written repair plan with a clear price.
We handle storm damage and urgent repair work for our clients. Our hours are Monday through Friday, 7:00 AM to 7:00 PM, and Sunday, 7:00 AM to 7:00 PM.

Call (361) 326-2313. You'll reach a live coordinator who connects you with the Houston team working on your project. We don't want you wondering who to contact at any stage of the build. From the first site walk with Russ Delmar to the final inspection and warranty period, there's one number and one team. Written communication matters too, so we document every change, every schedule update, and every question in writing. You'll always know where your project stands. Call (361) 326-2313 any time you have a question, during business hours.
Warranty & Guarantees FAQs
Every ADU we build is covered by The Kingswell Guarantee, and we put it in writing before your project starts. The guarantee promises four things: a written price before any work starts, a real arrival window, a clean job site, and a written guarantee on the work. If a repair fails inside the guarantee period, we come back and fix it at no charge. That's the whole arrangement, stated plainly. No fine print that disappears when you need it. Ask us for the written terms when you call (361) 326-2313, and we'll walk you through exactly what's covered and for how long.
The Kingswell Guarantee covers workmanship. If something we built fails inside the guarantee period, we come back and fix it at no charge. The specific term and coverage details are written out before your project begins, and you'll have that document in hand. The guarantee is the reason the Kingswell family put their name on this company. Every location that works under the Lodgewick name, including our Houston branch, works to the same four promises: written price before work, a real arrival window, a clean job site, and the written guarantee. If you want to read the full terms before deciding, call (361) 326-2313 and we'll send it over.
You call (361) 326-2313 and tell us what's wrong. If it's covered under The Kingswell Guarantee, we come back and fix it at no charge. That's the promise that backs every ADU we build in Houston. We'd rather hear about a problem early than have you live with it or hire someone else to patch it. The guarantee exists because the Kingswell family built this company for homeowners who've been let down before by contractors who vanish after the final check. That doesn't happen here. Call us, tell us what's happening, and we'll make it right.
Yes. Every repair, not just full ADU builds, is covered under the same Kingswell Guarantee. The repair price is written before we start, and the work is guaranteed in writing when we finish. If a repair fails inside the guarantee period, we come back and fix it at no charge. That applies whether we built the original ADU or not. If you've had a bad experience with a previous contractor and something they built is now failing, call (361) 326-2313. We'll assess it, give you a written price to correct it, and stand behind the repair the same way we stand behind every job.
That's a great question, and the answer depends on the terms of the specific guarantee in your written agreement. The best way to get a precise answer is to ask us directly and review your project documents together. In general, a permitted, inspected ADU with a documented warranty is an asset when you sell, and buyers in Houston increasingly ask for paperwork on the ADU specifically. We're happy to explain your warranty terms to a buyer or their agent at no cost. Call (361) 326-2313 and we'll walk through your specific situation.
