How to rebuild a home in Los Angeles after a wildfire: rules, permits, and what to expect
Wildfires have become an unfortunate reality for many homeowners in Los Angeles and surrounding areas. When a fire devastates a home, the emotional toll can be overwhelming, but once safety is ensured, the next critical step is understanding how to rebuild. Fortunately, the City and County of Los Angeles have developed specific guidelines to help streamline the process for fire victims.
This article will walk you through what it takes to rebuild a home in Los Angeles after a wildfire, from understanding zoning regulations and permit requirements to using local maps and working with the right professionals.
The aftermath of a wildfire: what to do first
After a wildfire, safety and damage assessment are your first priorities. Once evacuation orders are lifted and authorities give clearance to return, here’s what you should do:
Inspect the property: Assess the extent of the damage, but don’t enter structures unless officials declare them safe.
Document everything: Take detailed photos of damage for insurance claims.
File insurance claims: Start the process as soon as possible to avoid delays in rebuilding.
Contact local building officials: Determine if your property is in a designated fire zone and understand your eligibility for expedited rebuilding programs.
Wildfire rebuild zones in Los Angeles
The Los Angeles Department of Building and Safety (LADBS) and Los Angeles County Department of Regional Planning identify specific Wildfire Rebuild Zones. These zones allow affected homeowners to rebuild under streamlined processes. Your first step is to find out if your property falls within one of these areas.
Where to Check
LA County GIS Mapping Tool: Use this to locate your property and confirm if it's within a wildfire rebuild zone.
Fire Hazard Severity Zone Map: This state map designates areas with Very High Fire Hazard Severity, which impacts building code requirements.
LADBS Rebuild Program: The Rebuild LA program outlines steps for homeowners looking to rebuild after a disaster.
Rebuilding Under "Like-for-Like" Guidelines
One of the major benefits of being in a designated wildfire recovery area is the “like-for-like” rebuild option. This allows property owners to reconstruct homes that were lost in a fire with fewer delays and permit requirements—as long as the new structure matches the original in size and footprint.
What qualifies as Like-for-Like?
Same number of bedrooms and bathrooms
Same square footage (within 10%)
Same building footprint and location on the lot
Same number of stories
This route can help homeowners avoid some zoning reviews and environmental approvals, significantly speeding up the rebuilding process.
Permit requirements for fire rebuilds
Even with a like-for-like rebuild, permits are still required. Here’s what you’ll typically need:
1. Demolition permit
Before new construction begins, a demolition permit must be issued for clearing what’s left of the damaged structure.
2. Rebuild plan review
Submit building plans to the LADBS (for City of LA) or LA County Building and Safety (for unincorporated areas). This includes:
Site plans
Architectural drawings
Engineering calculations
Fire-resistant material specifications
3. Wildland-Urban Interface (WUI) compliance
Structures in fire-prone areas must meet WUI construction standards, including:
Class A roofing
Fire-resistant siding
Ember-resistant vents
Tempered glass windows
4. Energy Code (Title 24) compliance
Your rebuild must meet current energy efficiency standards. This may affect insulation, HVAC systems, and solar readiness.
5. Septic or sewer system review
If your property uses a septic system, it must be tested and possibly replaced. If you're on city sewer, reconnection may be needed.
Timeline: How long does rebuilding take?
The rebuilding timeline depends on several factors, including:
Whether your rebuild qualifies as like-for-like
The availability of your design-build team
Permit processing times
Construction supply chain issues
Estimated timeframes:
Plan and permit approval: 2–4 months
Construction: 6–12+ months (depending on size and complexity)
Working with an experienced design-build firm can streamline this significantly.
Choosing the right construction partner
Rebuilding after a wildfire isn’t just construction—it’s restoration. It requires:
Understanding of local rebuild regulations
Experience with fire-resistant materials and WUI codes
Project management that keeps timelines and budgets in check
That’s why many homeowners in Los Angeles choose to work with a design-build firm specializing in fire rebuilding.
Why Design-Build Works for Fire Rebuilds

Faster project delivery
Cost control from the beginning
Fewer surprises due to comprehensive planning
Firms like Alpha Build & Design, for example, focus on new construction and post-disaster rebuilding, offering in-house architecture and construction teams who are familiar with the complex permitting and zoning challenges in LA.
Key regulations to know
Here are the top local rules and standards to keep in mind during the rebuild process:
1. Fire-Resistant Materials
Mandatory in WUI areas, including:
Non-combustible siding
Class A roofing
Double-pane tempered glass
2. Brush Clearance and Defensible Space
LA County requires clearing vegetation at least 100 feet around your structure for fire prevention.
3. Setback Requirements
Even for like-for-like builds, you must comply with current setback rules—how far your home must be from property lines.
4. Accessory Dwelling Units (ADUs)
Rebuilding can be a great time to add a legal ADU to your property, which is now easier due to recent California legislation.
Final tips for a successful rebuild
Start early: Planning and permitting take time, so begin as soon as possible.
Choose local experts: Work with teams familiar with Los Angeles’ specific fire rebuild requirements.
Stay organized: Keep documentation from insurance, permits, and inspections in one place.
Communicate clearly: With so many moving parts, transparency with your contractor and city officials is critical.
Design for resilience: Consider upgrades like metal roofs, solar panels, and home sprinklers to reduce future risk.
