Adding a room to your Jacinto City home means working with a contractor who understands what’s under your floors. Most houses here in Jacinto City sit on pier-and-beam foundations from the 1940s and 1950s, and a room addition on that kind of ground behaves differently than one on a slab. We plan for that from day one. Our crews are familiar with Jacinto City’s permit office, setback rules, and the way older bungalows shift over time. If you’re thinking about a room addition, second story, sunroom, or bump-out, call (361) 326-2313 for a free estimate. We’ll come out, look at your foundation and roofline, and give you a written price before any work starts.

Why Lodgewick ADU Houston Is Jacinto City’s Preferred Home Addition Contractor Company

Russ Delmar leads our Jacinto City work, and he’s spent enough time under these houses to know what to expect before the first board comes off. Homeowners here tell us the same thing again and again: a previous contractor bid the framing but never mentioned the foundation. That’s the expensive surprise on Jacinto City’s older stock. We write the leveling, shimming, and strapping into the price up front. No change orders at the door.
We operate under The Kingswell Guarantee, which every Jacinto City homeowner gets in writing before we start: a written price, a defined arrival window, a clean job site, and a written guarantee covering the work for 365 days. If something isn’t done right, we come back and fix it. That’s the whole promise, on paper, before a single nail is driven.
When you call (361) 326-2313, a live person answers. Not a voicemail loop. Not a chatbot. If you have a question about your addition at 9 p.m., you’ll talk to a human. That matters when a permit inspection is scheduled or a crew is arriving the next morning.
Room Addition Contractor in Jacinto City
A room addition contractor in Jacinto City has to solve the foundation question before anything else. The original homes around Muscatine Street, Holland Avenue, and the blocks near Jacinto City Elementary were built on pier-and-beam. Beams settle. Floors slope. When we add a room to one of these houses, we typically jack and shim the existing perimeter first, then pour new concrete beams for the addition and tie them to the original framing with steel straps. Skip that step and your new room will separate from the old house within a few years.
A ground-floor room addition in Jacinto City commonly runs $180 to $320 per square foot, depending on whether we are adding a simple bedroom, a bathroom, or a primary suite with plumbing. A 400 sq ft room addition typically lands between $72,000 and $128,000 before finishes. Structural leveling on the existing side adds $3,000 to $9,000 on most 1940s-era homes.
Permit Sequence We Handle
Jacinto City requires the building permit placard posted at the street before any construction starts. We pull the permit, schedule the foundation inspection and framing inspection back-to-back where possible, and make sure the roofline ties into the original eaves with proper uplift strapping for our wind zone. A failed framing inspection over missing straps delays your project by weeks. We pre-check that before the inspector arrives.
Matching Original Details
Many Jacinto City bungalows have a specific lap siding profile from the 1950s. We match it with James Hardie lap siding so the addition reads as part of the original house, not a box stuck on the side. That matters for resale and for how the house looks from the street on a block where the neighbors have kept their homes original.
Second Story Addition Contractor in Jacinto City
A second story addition contractor in Jacinto City works with two constraints the national builders never think about: ground-floor ceiling height and pier-and-beam load capacity. The old bungalows here were framed for single-story living. The ceiling joists may be 2x6s, not 2x10s. Before we frame up, we verify the existing first-floor walls and beams can carry the second story, and we often add a new beam line through the center of the house.
Second-story additions in Jacinto City run $220 to $380 per square foot because they involve structural reinforcement, stairwell construction, and roofing integration. A 600 sq ft second story typically lands between $132,000 and $228,000. If the City of Jacinto City requires an electrical panel upgrade to handle the added load, that adds $2,500 to $6,000, and we’ll tell you in the written estimate, not after demolition starts.

Stairwell Placement on Small Lots
Jacinto City lots are narrow, often 50 feet wide or less. The stairwell has to borrow space from an existing room or a hallway, and that changes the first-floor plan. We walk you through that before you sign, so you’re not surprised when the stairs eat into a bedroom closet.
Roofline Integration
A second story that looks like an afterthought hurts the value of the whole house. We design the upper roofline to tie into the original eaves at the same pitch, and we use the same siding material to keep the house cohesive. On a recent primary-suite addition, we used James Hardie siding matched to the existing 1950s lap profile, and the city inspector passed the framing on the first visit.
Trusted Brands We Service in Jacinto City
We work with materials and systems that hold up in Jacinto City’s heat and humidity. For siding, we use James Hardie fiber cement almost exclusively on older homes because it expands and contracts predictably and handles the Gulf Coast moisture better than vinyl. For homeowners considering a prefab ADU or detached addition, we’ve installed units from Plant Prefab and Tuff Shed and know which models fit the lot dimensions and setback rules in Jacinto City’s R-1 zones. We keep common trim profiles and siding in stock for Jacinto City homes, which shortens the wait when a job needs matching materials.
Common Home Addition Contractor Problems We See in Jacinto City Homes
- Demo before the permit is posted. Jacinto City requires the permit placard on the street before construction begins. We’ve seen homeowners get stop-work orders because a contractor started tearing off siding before the placard went up. That costs weeks and sometimes fines.
- Pier-and-beam leveling hidden from the bid. A framing-only bid on a 1940s or 1950s home will blow up when the existing floor has to be jacked and shimmed before the addition ties in. Homes on Muscatine Street and nearby blocks often need $3,000 to $9,000 of leveling work before framing can start. We write that into the price up front.
- Roofline uplift strapping missed. Jacinto City’s wind zone requires specific metal strapping where the added roof meets the original eaves. Skip it and the framing inspection fails. We pre-install the strapping and have it inspected before sheathing goes on.
- Floodplain surprises on slab homes. The few slab homes in Jacinto City that sit near Halls Bayou or inside the 100-year floodplain may need the finished floor raised or flood vents added to the foundation. That changes the whole scope. We check the FEMA map before we bid, not after the hole is dug.

FAQs About Home Addition Contractor in Jacinto City
Jacinto City’s building permit covers the foundation work, but the foundation inspection is a separate step that must be scheduled and passed before framing can proceed. We handle the permit application, the placard posting, and both inspection bookings. Call (361) 326-2313 to get your project scoped, and we’ll walk you through the exact permit sequence for your street.
Jacinto City’s R-1 setbacks typically require five feet from the side property line and 20 to 25 feet from the front, but the exact number depends on your block and lot width. We verify the setback against your specific lot before we draw plans, so you don’t pay for design work on a footprint the city won’t approve. Call (361) 326-2313 for a free estimate and we’ll check your setback as part of it.
Often yes. Adding a second story means more circuits, and many Jacinto City homes still have 100-amp panels that won’t pass inspection under the added load. A panel upgrade to 200 amps typically runs $2,500 to $6,000, and we’ll tell you in the written estimate whether yours needs it. Call (361) 326-2313 and we’ll look at your panel during the free estimate.
The original 1940s and 1950s bungalows in Jacinto City often have 8-foot ceilings framed with 2×6 ceiling joists, which are undersized for carrying a second story. We typically add a new beam line through the center of the house and verify the first-floor walls before framing up. That’s a structural cost, not a design preference, and we put it in the written price. Call (361) 326-2313 for an exact quote.
If your slab home sits inside the 100-year floodplain, which affects certain blocks near Halls Bayou, the City of Jacinto City may require the finished floor of the addition to be raised or flood vents added to the foundation. That changes the scope before you ever pick a paint color. We check the FEMA map and the city’s floodplain overlay before we bid. Call (361) 326-2313 for a free estimate that accounts for your lot’s actual flood status.
