Fast, Reliable General Contractor Across Tarzana
If you’re planning a remodel in Tarzana, the first question is usually not “who can build it” but “what will it actually cost and will the price hold.” We give you a written price before any work starts. That’s the whole job of a General Contractor: line-item the scope, pull the permits, schedule the trades, and stand behind the result. Mason Remodeling has done that since 2004, and we know the specific issues Tarzana homes throw at you: 1950s ranch layouts, unpermitted additions from decades past, and soil that moves more than people expect. Call (803) 680-2547 and we’ll walk the project with you before you spend a dime.
Why Mason Remodeling Is Tarzana’s Preferred General Contractor Company

Tarzana homeowners tend to ask sharper questions than most. A lot of you have been through a remodel or heard the story from a neighbor on Avenida Hacienda or Melody Hills. You know the difference between a verbal estimate and a written price. We deliver the written price before tools come off the truck, every time, no exceptions. That’s not a sales pitch. It’s how Isaac Pruett runs every job Mason Remodeling takes on.
Every crew member who comes to your Tarzana home has been background-checked and identity-verified under the Threshold Standard. You get the technician’s name and photo before the visit. They show a photo ID badge at the door and wear a clean marked uniform. If you’re home alone, or you’re a parent keeping an eye on toddlers while contractors move through the house, that’s not a nice-to-have. It’s the point.
Our workmanship carries a 365-Day Done Right Promise. If something isn’t right within a year of completion, we return and fix it at no charge. No dispute process, no conditions. The guarantee terms are written on every project.

Residential General Contractor in Tarzana
Residential General Contractor work in Tarzana means managing the entire remodel from the first plan check at LA Department of Building and Safety to the final inspection. A full kitchen remodel with quality cabinetry and surfaces in Tarzana typically runs $14,000 to $45,000. A bathroom remodel runs $9,000 to $28,000. A home addition is $45,000 to $130,000 depending on square footage, foundation type, and structural work tied to the existing house. Those are honest ranges for this market, and they assume a real contractor who pulls permits, uses spec-grade materials, and doesn’t disappear mid-job.
Here’s what that looks like on the ground in Tarzana. Many homes between Vanalden Avenue and Reseda Boulevard, and north of Ventura Boulevard up into Melody Acres, are original 1950s and 1960s ranches built when lots were larger and building records were thinner. When we open a wall on those homes, we often find framing that was never permitted, or subfloor that’s been carrying load for sixty years without sistering. That’s exactly the kind of condition that blows up a budget if it’s discovered but nobody planned for it. We plan for it from the start.
Kitchen and bath scoping that accounts for the hidden stuff
A typical Tarzana kitchen remodel starts with a measured as-built and a permit check. We look at what’s on file with the city, compare it to what’s actually there, and flag anything that doesn’t match before we write the price. Original 1950s rough-in and subfloor often need replacement once demo starts. If allowances account for that, the job stays calm. If they don’t, the job stalls and the bill climbs.
Structural work, load-bearing walls, and unpermitted additions
When a wall that looks non-load-bearing turns out to be holding up the roof, the scope changes. That’s not a surprise fee. That’s construction. We write change orders in plain language, with the exact framing, shear wall, or beam required, and we get sign-off before we continue. You always know what the change costs and why it’s needed.
Hire a General Contractor in Tarzana

When you hire a General Contractor in Tarzana, you’re hiring someone to coordinate every trade, every inspection, every material delivery, and every question the city asks. That coordination is where projects succeed or fall apart. A Tarzana garage conversion runs $30,000 to $80,000 depending on whether it’s a simple finish job or a full ADU with its own kitchen, bath, and utilities. ADU construction runs $90,000 to $220,000 in this market because LA has strict planning and energy code requirements, and Tarzana’s older lots often need service panel upgrades or trenching for new sewer and gas lines.
The critical part is the contract. Verbal scopes cause most mid-project disputes. Our written scope includes allowances, inclusions, exclusions, and the draw schedule. You see the exact price of every allowance line before demo starts. If the job reveals a hidden condition, the change order is in writing, with a cost, before work continues.
Draw schedules that don’t leave you exposed
A good draw schedule ties payments to completed milestones: demo and rough framing, rough mechanicals, drywall and finishes, final inspection. You never write a check for work that hasn’t happened. We run draws on a written schedule and hold the final payment until the last inspection passes and the punch list is signed off.
Permits and inspections handled start to finish
Tarzana falls under the City of Los Angeles. That means LA Department of Building and Safety permits and inspections on almost every remodel beyond paint and flooring. We pull the permits, schedule the inspections, meet the inspector on site, and fix any corrections. You don’t chase the city. That’s our job.
Trusted Brands We Service in Tarzana
Older Tarzana ranches often have a charm worth preserving, and some homeowners here are doing more than one project at a time. For foundation and concrete work on additions, we specify Sakrete mixes that hold up to the area’s reactive clay soil, which expands and contracts with the seasons. Homeowners adding a prefab ADU or a backyard unit often ask about Abodu or Dvele, and we coordinate those installations with the site work, utilities, and city approvals. For traditional stick-built additions, Cover’s prefab panels can shorten framing time on a tight Tarzana lot. We stock common repair materials and access these brands quickly for Tarzana customers, so downtime stays short.

AfterCommon General Contractor Problems We See in Tarzana Homes
- Unpermitted original additions and converted lanais. Because much of Tarzana was built on former Melody Acres ranch land in the 1950s and 60s, many homes have enclosed patios, detached garages turned into living space, or room additions that were never recorded with LA Building and Safety. Opening a wall and finding an old exterior stucco line behind the drywall is common, and the inspector will stop the whole job until the as-built drawings are reconciled.
- Original 1950s subfloor and rough-in that fails once exposed. Ranch-era homes around Vanalden Avenue and Avenida Hacienda often have subfloor that’s fine under carpet and furniture but too far gone for new tile or hardwood. The rough-in framing underneath sometimes needs sistering or replacement, which is a hidden cost that should be in the allowance from day one.
- Verbal scopes that fall apart mid-project. A project priced off a conversation has no allowance structure, no change order process, and no clear draw schedule. When demo finds something unexpected, the dispute starts. Every Tarzana project we run has a written scope, written allowances, and written change orders. Nothing verbal.
- Garage conversions that don’t meet current ADU code. Many Tarzana garages from the 1950s and 60s were built on slab foundations with old electrical service and no insulation. Converting one to a legal ADU usually requires a panel upgrade, new foundation anchors, insulation, and often a new sewer lateral. We scope that up front so the cost doesn’t surface at rough inspection.

FAQs About General Contractor in Tarzana
Yes. Nearly any kitchen or bathroom remodel in Tarzana that moves plumbing, electrical, or walls requires a permit from LA Department of Building and Safety. The city also wants to see that any prior work on the house was permitted before new work is signed off. We reconcile that before demo starts, so the project doesn’t stall at first inspection. A good rule: if we’re touching structure, water, gas, or wiring, we’re pulling a permit. Call (803) 680-2547 and we’ll tell you what applies to your specific house.
A full Tarzana kitchen remodel typically takes 8 to 12 weeks from demo to final inspection, assuming permits are filed at the start and no major structural surprises surface. If we’re reconciling unpermitted prior work or adding a beam, add two to three weeks for plan check and re-inspection. We give you a written schedule at contract, and we update it in writing if conditions change.
The two most common cost changes in Tarzana are structural: a wall that turns out to be load-bearing, in which case we add a beam or shear wall by written change order, and original 1950s subfloor or rough-in that has to be sistered or replaced before finishes go in. Both are genuine conditions, not padding. We write every change order with a specific cost and get your sign-off before we continue. That’s the whole point of a written scope with allowances.
Yes. A legal ADU conversion in Tarzana typically runs $90,000 to $220,000 depending on the existing garage condition, whether you need a new service panel, and whether the lot requires trenching for new sewer, water, or gas lines. The city’s current ADU rules make this more feasible than it used to be, but the older the garage, the more structural and utility work is usually involved. We scope it accurately before you commit.
We tie every draw to a completed milestone: demo and rough framing, rough mechanicals, drywall and finishes, final inspection. The schedule is in your contract in writing. You don’t pay for work that hasn’t happened, and final payment isn’t due until the last inspection passes and the punch list is signed. Call (803) 680-2547 and Isaac Pruett will walk you through exactly how the draws work on your specific project.
