Short Answer

1 Smart Build is a licensed design-build general contractor (CSLB #1076428) rebuilding homes lost in the January 2025 Eaton Fire in Altadena. Because Altadena is unincorporated, permits run through Los Angeles County Public Works rather than a city building department. We document the loss for your carrier, take the plans through county plan check, and rebuild to current wildfire construction standards. Planning range is $350 to $650 per square foot, and 18 to 30 months from claim to certificate of occupancy.

Credentials: 1 Smart Build Inc. Licensed and insured. CSLB #1076428, Class B. Owner-operated.

Altadena Is Unincorporated, So The County Permits It

Altadena has no city hall of its own. Plan check, permits and inspections are handled by Los Angeles County Public Works Building and Safety, with county planning reviewing zoning and any nonconforming conditions. That is a different submittal, different fee schedule and different inspection process than a Pasadena or City of Los Angeles rebuild, and it is worth confirming your parcel's jurisdiction before you hire anyone.

County plan check and inspections, not a city department
County-run rebuild permit assistance for Eaton Fire parcels
Zoning, setback and nonconforming review by county planning
Debris clearance and soil testing documented before permits

Rebuilding Altadena's Older Housing Stock

Much of Altadena was built from the 1920s through the 1950s: Craftsman bungalows, midcentury ranches, detached garages and additions built over decades. Original permit records are often incomplete, so establishing the legal pre-fire square footage and unit count is one of the first things we do, since it sets what you can rebuild by right.

Pre-fire square footage and unit count established from county records
Unpermitted prior additions identified early
Detached garages and accessory structures scoped separately
Option to add a permitted ADU alongside the main house rebuild

Wildfire Construction Standards In The Foothills

Altadena sits against the San Gabriel foothills in a Very High Fire Hazard Severity Zone, so the rebuild is designed under California's wildfire construction requirements (Building Code Chapter 7A). Those assemblies are specified in the drawings before pricing, so the estimate reflects what will actually pass inspection.

Ignition-resistant or noncombustible siding, eaves and soffits
Ember-resistant vents at attic and crawl space
Multi-pane tempered glazing and rated doors
Class A roof assembly with protected edges and valleys
Defensible space clearance planned with the landscape scope

Insurance Scope And Underinsurance

Many Altadena homeowners are rebuilding a home that was insured years ago at a much lower replacement cost. We give you a line-item construction scope early enough to see the gap, and we can phase the rebuild or right-size the plan instead of discovering the shortfall halfway through framing.

Line-item scope written for adjuster review
Code upgrade coverage identified separately
Phasing options when the claim falls short of the rebuild cost
Draw schedule matched to insurer payment stages

FREQUENTLY ASKED QUESTIONS

Who issues building permits in Altadena?

Altadena is unincorporated Los Angeles County, so permits and inspections come from Los Angeles County Public Works Building and Safety, with county planning reviewing zoning. It is not permitted by the City of Pasadena or the City of Los Angeles.

How much does an Eaton Fire rebuild cost in Altadena?

Planning range is $350 to $650 per square foot. Wildfire-rated exterior assemblies, foundation work, utility reconnection and the finish level chosen are what move a specific project inside that range.

How long will my Altadena rebuild take?

Expect 18 to 30 months from claim to certificate of occupancy, including roughly 4 to 9 months of design, engineering and county plan check before construction starts.

Can I add square footage or an ADU while rebuilding?

Usually yes. Rebuilding near the original footprint is the fastest approval path, and many owners add a permitted ADU or a modest expansion in the same submittal. We price both options so you can compare the cost and the added review time.

What if my insurance payout is less than the rebuild cost?

That is common in Altadena because of older policy limits. We show you the line-item cost early, then look at phasing, plan size and finish level so the decision is made before construction starts rather than during it.

What are my cancellation rights after a disaster?

For repair or restoration of a home damaged by a declared disaster, California law gives you until midnight of the seventh business day after signing to cancel without penalty (Civil Code 1689.6). In addition, a home solicitation contract signed within 7 business days after the disaster is void unless you, your agent or your insurer initiated the contact at our place of business (Civil Code 1689.14). Every contract we sign includes a Notice of Cancellation form. We price disaster rebuilds at our standard pricing, with no emergency premium.

Permit requirements change, so confirm current rules with Los Angeles County Public Works Building and Safety, through the county's Altadena rebuild permit center before you rely on any timeline here.
