AfterRemodeling Company in Altadena, CA
Home remodeling in Altadena now means rebuilding after the January 2025 Eaton Fire and bringing surviving homes up to California’s strict Wildland-Urban Interface standards. We’re Penhallow Remodeling, and we handle whole-home remodels, fire rebuilds, and room-by-room renovations for Altadena homeowners navigating Chapter 7A compliance, LA County permitting, and the challenge of preserving neighborhood character with fire-resistant materials. Our crews serve Altadena from our Los Angeles office, and you can reach us at (936) 259-2607 to schedule a free written estimate.
Why Altadena Homes Are Different
Altadena sits at the base of the San Gabriel Mountains in an unincorporated pocket of Los Angeles County, which means every permit runs through the LA County Department of Public Works rather than a city building department. After the Eaton Fire destroyed more than 7,000 structures here, the County created a dedicated fire rebuild permitting track with its own inspectors and streamlined plan-check timelines, separate from standard County processes. Contractors working in Altadena must know both tracks.
The local housing stock compounds the complexity. Pre-fire Altadena was dense with 1920s Craftsman bungalows, Spanish Colonial Revivals, and post-war ranch homes, many built with open-eave wood framing and lap siding that are now prohibited under mandatory WUI rebuild codes. Reconstruction has to reconcile historic neighborhood character with ignition-resistant framing, ember-resistant vents, Class A roofing, and non-combustible exterior assemblies. And because Santa Ana winds funnel through these mountain canyons driving ember cast for miles, virtually all of Altadena falls within the Very High Fire Hazard Severity Zone, so Chapter 7A applies to new construction everywhere in the community, not just fire rebuilds.

Whole House Remodel
Signs you need it
Your home was damaged or destroyed in the January 2025 Eaton Fire, or your surviving pre-1950s home still has original wood framing, open eaves, and lap siding that no longer meets Altadena’s mandatory WUI codes.
What it costs in Altadena
A whole house remodel in Altadena typically runs from $45,000 to $130,000 for renovation work, while fire rebuilds and home additions start at $45,000 and can reach $130,000 depending on square footage, WUI-compliant material selections, and foundation requirements.
How we do it
We start with structural assessment and asbestos/lead testing common in pre-1950s Altadena homes, then draft WUI-compliant plans for the County’s fire rebuild track, install ignition-resistant framing and ember-resistant vents, apply Class A roofing and non-combustible exterior assemblies, and finish with interior systems and final inspection.
Home Renovation
Signs you need it
Your Altadena home survived the fire but needs systems updates, layout changes, or cosmetic renovation that triggers Chapter 7A compliance for any exterior work or additions.
What it costs in Altadena
Home renovation in Altadena typically ranges from $9,000 to $45,000 depending on scope, with kitchen renovations running $14,000 – $45,000, bathroom renovations $9,000 – $28,000, and smaller projects like backsplash installation $800 – $2,500.
How we do it
We assess which elements trigger WUI compliance, write a line-item price for each phase, schedule work around LA County inspection windows, use moisture-resistant cement board substrate where tile meets water, and complete with our 365-Day Done Right Promise in writing.

FAQs About Remodeling Company in Altadena
LA County’s standard residential permitting takes 4 – 8 weeks for plan check, but Altadena fire rebuilds qualify for a dedicated track with streamlined timelines and assigned inspectors. We submit complete plans to avoid revision cycles, and we handle every step.
Yes. Virtually all of Altadena sits within the Very High Fire Hazard Severity Zone, so any new construction, addition, or exterior alteration must comply with Chapter 7A standards for ignition-resistant materials, ember-resistant vents, and Class A roofing regardless of whether the original structure burned.
We can replicate historic profiles using WUI-compliant materials, such as fiber-cement siding with Craftsman-style reveals, non-combustible trim that mimics original wood details, and fire-rated windows with divided-light patterns. We write the approach and price into your estimate before work starts.
