Fast, Reliable Home Addition Contractor Across Mid-City

A home addition in Mid-City typically runs between $85,000 and $240,000 depending on whether you’re adding a bathroom, a bedroom, or both, with most projects landing in the $110,000 to $160,000 range once plans, permits, and site work are included. The fastest way to know your number is to call (903) 568-7222 and get a written price before any work starts. That’s how we work at Benson ADU Builders, and it’s why Mid-City homeowners call us first when they’re tired of verbal estimates that shift the moment a plan check comes back.

Call (903) 568-7222

We know Mid-City’s streets because we work them every week. Our Home Addition Contractor team has scoped additions up and down Pico, West Adams, and the side streets off Crenshaw, and we understand what the Mid-City West Community Plan does to a project before the first wall goes up. You want a contractor who can tell you the truth about your lot on the first visit, not one who discovers it after demolition. Call (903) 568-7222 for a free estimate and a straight answer.

Why Benson ADU Builders Is Mid-City’s Preferred Home Addition Contractor Company

A single-story rear room addition with tall windows and a new patio

We built our reputation in Mid-City the slow way: one permitted addition at a time, with a written price on the table before a single board was cut. Homeowners here deal with aging foundations, tight rear yards, and a planning department that has seen every shortcut. When we walk a 1940s bungalow on a 5,000-square-foot lot, we already know the rear yard coverage math before we step into the backyard. That local familiarity is why Mid-City residents keep our number saved.

Every Benson crew member who steps onto your Mid-City property is background-checked and in uniform. You know exactly who is at your door. Our 365-Day Done Right Promise means if the work isn’t right within a full year, we make it right, and that guarantee is stamped in writing on your project. No other contractor serving Mid-City pairs that promise with access to prefab brands like Cover and Dvele, which means you get options most homeowners here never see.

Scheduling and dispatch are coordinated from our Los Angeles office, with crews serving Mid-City locally, so you’re not waiting on a crew from across the county. A live person answers every call, around the clock, every day of the year. No voicemail loops, no phone tag. That matters when you’re in the middle of a foundation pour and need an answer in five minutes, not five days.

Bathroom Addition Contractor in Mid-City

A bathroom addition in Mid-City means more than roughing in a toilet and a shower; it means matching a new wet wall to a 70-year-old plumbing stack and making sure the slab pour is coordinated before the concrete truck arrives. The homeowners we talk to on streets off La Brea and Fairfax are usually adding a second bath because the original 1948 floor plan has one bathroom serving three bedrooms. A full bathroom addition in Mid-City typically runs $35,000 to $65,000 when done as part of a larger addition scope, and a standalone bath addition starts around $45,000.

The mistake we see too often is pricing a bathroom addition as its own project, then realizing two months later that the bedroom next to it needs a foundation extension too. That double pour is the single most avoidable cost in Mid-City additions. We lay out the full scope in one meeting so the bathroom rough-in goes into the slab the first time, not the second.

Foundation and Rough-In Coordination

A bathroom addition on a pier-and-beam bungalow near Pico and Crenshaw needs the new stem wall matched to the old foundation before framing starts. We survey the existing piers, check the sill plates, and set the rough-in depth so the toilet flange sits exactly where the plan says it will. Skipping this step is how Mid-City homeowners end up with a jackhammer back in the slab two weeks after the pour.

Permit-Ready Plans Before You Commit

We pull LADBS permits ourselves and stand with you through every inspection. The plumbing, electrical, and structural checks are scheduled by us, and you get a written price for the permit-ready plan set before any work begins. No homeowner in Mid-City should be the one chasing a plan checker on a Tuesday morning.

Bedroom Addition Contractor in Mid-City

A new sunroom addition with three walls of windows

A bedroom addition in Mid-City is often the difference between keeping a growing family in a house they love and moving out of the neighborhood entirely. The bungalows and duplexes built between the 1930s and 1950s along streets like West Adams and Pico were framed for smaller households, and adding a 250 to 400 square foot bedroom off the back is usually the most practical way to gain space without losing the yard. A bedroom addition in Mid-City typically runs $55,000 to $95,000 depending on whether it includes a closet, a bath, or both.

What most Mid-City homeowners don’t expect is how much the existing foundation dictates the price. A 1948 pier-and-beam foundation with a soft sill plate adds a structural repair line item before the addition even starts. We find that on nearly a third of the bungalows we scope in Mid-City, and we tell you about it in the written price, not after the demo crew leaves.

Matching the Old House Without Fighting It

We frame additions with 2×6 walls and cladding from James Hardie, which gives the new section a chance to stand up to Mid-City’s hot, dry summers and the occasional winter rain without warping or cracking. The goal is an addition that looks like it grew with the house, not a box bolted to the back of it. Our crew matched a bedroom-and-bath addition to a 1948 bungalow near Pico and Crenshaw so the roofline followed the original pitch, and the neighbor two doors down asked the homeowner for our number before we’d even finished trim.

One Concrete Pour, Not Two

When a bedroom and a bathroom are added together, the foundation pour happens once. When they’re treated as separate starting points, you pay for a second pour, a second LADBS plan check, and a duplicated inspection cycle. We scope both in the same meeting so the slab is poured once and the framing goes up in sequence, not in spurts.

Trusted Brands We Service in Mid-City

Benson ADU Builders is authorized to build with prefab brands Mid-City homeowners can research and trust on their own: Cover, Dvele, and Boxabl among them. That means when we talk about panelized construction or factory-built precision, we’re naming specific manufacturers, not waving at a vague “modern method.” For Mid-City customers, we keep local parts availability in mind and coordinate delivery windows with the manufacturer so you’re not paying for a driveway full of panels with nowhere to put them. The choice between a site-built addition and a prefab panel system is yours, and we put both options in writing with real numbers before you pick.

Common Home Addition Contractor Problems We See in Mid-City Homes

  • Skipped structural or boundary survey on 1940s bungalows. The sill plates and rear-yard coverage limits on a 1948 house near Pico can end a project if they’re discovered after demolition. We survey first and price the fix before the first board comes off.
  • Bathroom and bedroom additions scoped as separate jobs. That means two foundation pours, two plan checks, and two inspection cycles on a lot that only needed one. We lay out the full scope in one meeting.
  • Fixed prices quoted before LADBS plan check sign-off. A verbal number before plan check is a guess. A written price after plan check and field inspection is a contract. Mid-City homeowners deserve the second one.
  • Pre-construction surprises passed to the homeowner mid-job. When a soft sill plate or a boundary issue appears after demo starts, the bill should not appear at your door. Our upfront written price covers the pre-construction checks that catch those problems before they become change orders.

In Mid-City, the specific combination of 1930s to 1950s pier-and-beam foundations, compact infill lots, and the Mid-City West Community Plan’s coverage and height limits means the addition’s footprint is usually the first thing that determines whether it can be permitted at all, not the finishes. We start every Mid-City estimate with a lot survey and a foundation check because that’s where the real cost hides.

Pricing for Home Addition Contractor in Mid-City, CA

Mid-City addition pricing starts with the foundation and the lot, not the tile. A bedroom addition runs $55,000 to $95,000. A bathroom addition runs $35,000 to $65,000 as part of a larger scope, or $45,000 standalone. A combined bedroom-and-bath addition typically lands between $110,000 and $160,000, and that number includes the architectural plans, LADBS permits, foundation work, framing, mechanical rough-in, drywall, and the finishes you pick.

What moves the number is what we find in your foundation, your rear yard coverage limit, and your plan check. A 400-square-foot addition with a simple gable roof and one wet wall is the bottom of the range. A 600-square-foot addition with a full bath, a walk-in closet, and structural upgrades to the original sill plates is the top. Call (903) 568-7222 and we’ll walk your lot, measure your coverage, check your piers, and give you a written price before any work starts. Free estimate, no verbal guesswork.
