Our crews know the 77510 zip code well, from the older ranch houses off Avenue G to the newer subdivisions near State Highway 6.

We’re Lodgewick ADU Houston, part of the Kingswell family of home-service companies. Every Santa Fe project starts with a written price, a real arrival window, and a written guarantee. Russ Delmar runs our Houston operation and holds every crew to the same standard: say the price before the work, show up when promised, leave the job site cleaner than we found it.
Why Lodgewick ADU Houston Is Santa Fe’s Preferred Home Addition Contractor Company
Santa Fe homeowners keep calling us back because we put everything in writing. That’s not a slogan. The Kingswell Guarantee means you get a written price before a single nail is driven, a defined arrival window for the crew, and a written guarantee on every project. If something fails within 365 days, we come back and fix it at no charge. That’s the 365-Day Done Right Promise, and it’s delivered on paper before work begins.
Russ Delmar has built our reputation on the kind of straight answers Santa Fe residents don’t always get from contractors. When a homeowner off Avenue E asks whether their addition needs helical piers, we don’t hedge. We pull the FEMA flood map, check the base flood elevation, and tell them exactly what the foundation will cost. When someone near Runge Park wants a garage addition, we check CenterPoint’s service requirements before we quote so there are no surprise trenching charges at the end.
Every technician who steps onto a Santa Fe property is background-checked and uniformed. You’ll know who’s on your land, what they’re doing that day, and when they’ll be done. Calls to (361) 326-2313 are answered by a live person, 24 hours a day, seven days a week.
Second Story Addition Contractor in Santa Fe
A second story addition contractor in Santa Fe has to solve one problem most other cities don’t: adding vertical load to a slab-on-grade foundation that may sit in a 100-year floodplain. Most Santa Fe ranch homes built in the 1960s and 1970s were never engineered to carry a second floor. Before we frame anything, we assess the existing slab, soil conditions, and elevation certificate. On a typical second-story addition in Santa Fe, expect to pay $120,000 to $220,000. The lower end assumes your existing foundation can be reinforced with minimal pier work. If the first floor sits below base flood elevation, the price climbs because the entire addition footprint may need to be elevated.
Structural Assessment Before Framing
Santa Fe’s flat, bayou-adjacent terrain means high water tables under a lot of 77510 parcels. We bring in a Texas-licensed structural engineer to stamp the plans before the city sees them. That letter is often the difference between a permit in three weeks and a permit in three months. Our crew handles the engineering coordination so you don’t have to chase anyone.
What a Second Story Costs in 77510
Plan on $120,000 for a basic two-bedroom second story over a reinforced slab. Add $15,000 to $30,000 if helical piers are required to carry the new load. James Hardie lap siding to match the existing 1970s ranch exterior adds $9 to $12 per square foot installed. We quote all of this in writing before work starts, so there are no line items that appear halfway through the build.
Garage Addition Contractors in Santa Fe
Garage addition contractors in Santa Fe have to plan around elevation requirements that don’t apply in Dickinson or Friendswood. A detached garage addition on many 77510 parcels needs finished floor elevation at least 24 inches above base flood elevation. That means stem walls, fill, or piers before the slab ever gets poured. Budget $45,000 to $85,000 for a standard two-car garage addition in Santa Fe, with the higher end reflecting pier-and-beam foundations and electrical service upgrades.
Floodplain Elevation and Foundation Types
Our crew recently framed and tied in a garage addition off Avenue G where the homeowner wanted a shop space with a studio above. We pulled the 100-year floodplain elevation cert, drove helical piers to raise the stem walls 24 inches above base flood elevation, and sheathed the whole thing in James Hardie lap siding so the addition would match the existing 1970s ranch and pass the city’s final elevation inspection. The second-story studio got painted a week early because the pier schedule beat the rain window.
Electrical Service for Detached Additions
CenterPoint requires a new 200A lateral for any second dwelling unit on a Santa Fe property. That’s a $4,000 to $8,000 trenching charge if your existing panel is undersized. We check the utility requirements before we quote, not after the slab is poured. Homeowners who skip this step get stuck with a last-minute change order that could have been in the original written price.
Trusted Brands We Service in Santa Fe
We work with established prefab and materials brands that hold up to Santa Fe’s humidity and floodplain conditions. James Hardie lap siding is our default exterior because it resists the moisture that comes with bayou-adjacent lots and holds paint through Galveston County summers. For homeowners who want a faster build, we install Boxabl and Plant Prefab units as garage conversions or standalone ADUs, then handle the site work, foundation, and tie-in. Tuff Shed shells are common starting points in Santa Fe, but converting one to a legal home addition requires permits, elevation certs, and utility work we coordinate in-house. We keep local stock for common James Hardie profiles and prefab connection hardware so Santa Fe projects don’t stall waiting on a shipment.
Common Home Addition Contractor Problems We See in Santa Fe Homes
- Slab quotes that ignore the flood map. A contractor quotes slab-on-grade without checking the FEMA flood map. The city rejects the foundation permit because the finished floor is below the required BFE, adding five figures in piers or fill. We pull the elevation certificate before we quote any Santa Fe foundation.
- Framing shear wall inspections that stall for weeks. The Santa Fe building official wants a stamped letter from a Texas-licensed engineer for any wall over 60% glazing. Crews that skip this step lose two to four weeks waiting on paperwork. We file the engineering package with the permit application.
- Hidden electrical service upgrades. Homeowners assume a detached garage addition doesn’t need a separate electrical service update. CenterPoint requires a new 200A lateral for any second dwelling unit, causing a last-minute $4,000 to $8,000 trenching charge. We flag this in the original written estimate.
- Mismatched siding and moisture intrusion. Santa Fe’s humidity punishes cheap lap siding. We see additions where the siding swells and gaps open within two years. James Hardie lap siding with proper flashing is standard on our Santa Fe builds, and it’s covered under the written guarantee.

FAQs About Home Addition Contractor in Santa Fe
Not every addition, but most do. If your parcel falls within a 100-year floodplain designation, the finished floor of any habitable addition must sit at least 24 inches above base flood elevation. Detached garages with living space above follow the same rule. The only way to know for sure is to pull the FEMA flood map and elevation certificate for your specific lot, which we do before quoting any Santa Fe foundation. Call (361) 326-2313 and we’ll check your parcel at no charge.
You need a structural engineer to determine whether the existing slab can carry the added load. Most 1960s and 1970s Santa Fe slabs were not designed for a second floor, so helical piers or additional footings are usually required. The engineer stamps the plans, the city reviews them, and then framing begins. Budget $120,000 to $220,000 for the full project. Call (361) 326-2313 to get a written scope and price for your specific house.
Plan on two to six weeks for a garage addition permit in Santa Fe. The timeline depends on whether your lot is in the floodplain and whether the city requires an engineered elevation letter. Permits for simple bump-outs on high ground can clear in two weeks. Garage additions in the floodplain take longer because the foundation design goes through extra review. We submit the full package at once so the permit office doesn’t have to ask for missing paperwork. Call (361) 326-2313 for a realistic timeline on your specific project.
Santa Fe building officials require a stamped letter from a Texas-licensed engineer for any wall with more than 60% glazing. That’s not common in every city, but it’s standard here. There’s also a final elevation inspection for any addition in the floodplain. We schedule inspections and have the engineering letters ready before the inspector arrives, which keeps the job moving instead of stalling. Call (361) 326-2313 and ask Russ Delmar about the inspection sequence for your project.
Yes, but it requires permits, an elevation certificate, and utility work. A Tuff Shed or Boxabl unit cannot simply be dropped on the ground and called a home addition. The foundation must meet Santa Fe’s floodplain requirements, and CenterPoint requires a separate electrical service for any dwelling unit. We handle the conversion start to finish, including the foundation, tie-in, and permit closeout. Call (361) 326-2313 for a written quote on a prefab conversion in Santa Fe.
