AfterRemodeling Company in Granada Hills, CA
Home remodeling in Granada Hills runs $14,000 – $130,000 depending on scope, with most whole-house projects landing between $45,000 and $130,000 once we account for the area’s mixed-era construction. We’re Penhallow Remodeling, and we handle kitchen remodels, bathroom renovations, and whole-home transformations for homeowners in this northwest San Fernando Valley community. Our crews coordinate scheduling through our Los Angeles office and work Granada Hills properties regularly, so we know the local permit landscape and the specific headaches that come with 1950s – 70s ranch stock. Call us at (936) 259-2607 for a free written estimate.
Why Granada Hills Homes Are Different
Granada Hills sits within a few miles of the 1994 Northridge earthquake epicenter, leaving the neighborhood’s predominantly 1950s – 70s ranch-home stock with a complicated, layered construction history. Original framing, emergency post-quake repairs, and subsequent seismic retrofits often coexist inside the same structure. Every significant remodel or addition here begins with an audit of that mixed-era work, because unpermitted quake repairs routinely hide inside walls and under slabs, and LADBS inspectors in this corridor have seen enough of it to look for it specifically.
The northwestern San Fernando Valley location puts Granada Hills under a pronounced heat-island effect, with summer highs routinely reaching 105 – 110°F. Concrete pours and roofing work must be scheduled for pre-dawn starts in July and August or risk failed cures and heat-related shutdowns. Properties along the northern edge bordering the Santa Susana foothills fall within Los Angeles’s Very High Fire Hazard Severity Zone, mandating Chapter 7A ignition-resistant construction for any new build or substantial addition.
Most of the housing stock has crossed the 50-year threshold that triggers heightened LADBS historical review and mandatory asbestos/lead surveys before demolition. It’s common for a routine kitchen-remodel permit to stall when the inspector flags unpermitted post-Northridge sistering, non-code holddowns, or mismatched shear panels discovered once drywall comes down, effectively forcing the homeowner to retroactively engineer and permit 30-year-old earthquake repairs before the current project can advance.
Our Main Granada Hills Services
Granada Hills homeowners most often call us for two types of projects: full-room renovations that modernize aging kitchens and baths, and larger whole-home transformations that reconfigure the classic ranch layout for contemporary living. Here is what each involves in this market.
General Contractor in Granada Hills
As general contractors in Granada Hills, we manage the full scope of residential construction, from structural modifications and room additions to coordinating the specialized trades that earthquake-era homes demand. We open walls knowing we may find original 2×4 framing, emergency OSB shear panel overlays, and foundation anchor bolts installed under disaster-relief permits with varying levels of engineering oversight. Our job is to sort that history, bring it to code, and build on top of it cleanly. General Contractor in Granada Hills
Bathroom Remodeling in Granada Hills
Bathroom remodeling in Granada Hills means working around galvanized supply lines, cast-iron drains, and the occasional slab leak that comes with 60-year-old plumbing infrastructure. We replace failing fixtures with Kohler and Moen products, install moisture-resistant cement board substrate behind every tile surface, and pull permits through LADBS with full asbestos surveys when demolition touches original materials.

Kitchen Remodeling in Granada Hills
Kitchen remodeling in Granada Hills often starts with removing a wall to open the classic ranch floor plan, which means we immediately encounter the neighborhood’s layered construction history. We install KraftMaid and Wellborn cabinetry, Cambria and Silestone countertops, and we engineer every structural change to current seismic standards because inspectors here specifically check for post-Northridge holddowns and shear continuity.

Home Remodeling in Granada Hills
Home remodeling in Granada Hills demands more upfront investigation than in newer markets because the housing stock carries earthquake-era repairs that were often done fast and not always done to code. We regularly open walls in Granada Hills homes to find a patchwork of original 2×4 framing, emergency OSB shear panel overlays, and foundation anchor bolts installed under disaster-relief permits with varying levels of engineering oversight. Before we quote a whole-house remodel, we audit that mixed-era work so the number we put in writing accounts for the engineering and permitting it takes to make the structure sound. Home Remodeling through Penhallow means that audit is built into our process, not a surprise change order after demo day.
Whole House Remodel
Signs you need it
Your floor plan still reflects 1960s living patterns with closed-off kitchens, single bathrooms, and no master suite, while your electrical panel, plumbing, and HVAC are original or piecemeal-replaced.
What it costs in Granada Hills
A whole house remodel in Granada Hills typically runs $45,000 – $130,000, with the upper end reached when we must retroactively engineer and permit unpermitted post-Northridge repairs before current work can advance.
How we do it
We start with a structural audit of the mixed-era framing, pull LADBS permits with mandatory asbestos and lead surveys, sequence the work to minimize re-occupancy time, and finish with our 365-Day Done Right Promise in writing.
Home Renovation
Signs you need it
Your home is functionally intact but dated, with worn finishes, inefficient windows, and a kitchen or bath that hasn’t been touched since the original build.
What it costs in Granada Hills
Home renovation in Granada Hills typically ranges from $14,000 for focused room updates to $55,000 for multiple spaces, not including the additional engineering costs if unpermitted quake repairs are discovered.
How we do it
We develop a phased scope that prioritizes the rooms you use most, source materials from recognized trade brands, and schedule exterior work for pre-dawn starts during summer months to avoid heat-related shutdowns.

How long does a whole house remodel take in Granada Hills?
Most whole house remodels in Granada Hills take 4 – 8 months from permit to final walkthrough, with the timeline extending if LADBS discovers unpermitted post-Northridge repairs that require retroactive engineering. We build that possibility into our schedule and communicate weekly so you are never guessing where the job stands. Call (936) 259-2607 and we will walk you through a realistic timeline for your specific property.
Will my Granada Hills remodel need seismic upgrades?
If your home was built between 1955 and 1975 and has not had a formal retrofit, any significant remodel that opens walls or modifies the structure will likely trigger current seismic standards. We audit for original holddowns, shear panel continuity, and anchor bolt spacing during our initial site visit, and we engineer any gaps before LADBS sees them. Call (936) 259-2607 to schedule that audit with your free estimate.
