How Much Does a Balcony Replacement Cost in Los Angeles, CA?

The cost to replace a balcony in California varies based on location, structure type, and extent of damage. On average, property owners can expect to pay between $40,000 and $60,000 per balcony, but in high-cost regions like West Hollywood and Los Angeles, that number often rises to $50,000–$60,000+ per balcony.

These costs apply to homeowners, HOAs, and apartment complexes, especially when damage involves cantilever balconies that extend into the building structure.

What Drives Balcony Replacement Costs?

1. Structural Damage

Water intrusion and dry rot are the leading causes of balcony failure. When the rot spreads to load-bearing joists, a full replacement is required. Minor surface damage can be repaired, but deep structural rot demands removal and reconstruction.

2. Material and Labor Costs

• Wood/LVL/Glulam beams: Lower cost, but must be properly sealed and waterproofed.

• Steel or composite systems: More durable but higher material cost.
  Labor rates in urban areas like West Hollywood and Santa Monica can also add 20–30% to project totals.

3. Accessibility

High balconies or tight job sites may require scaffolding or lifts, adding several thousand dollars in labor setup.

4. Permitting and Engineering

For major structural work, permits typically range from $900–$15,000, and engineering design plans can cost $15,000–$28,000.

5. Waterproofing

Installing a proper waterproofing membrane is essential. Cutting corners here leads to premature failure and costly repairs later.

Real Example: West Hollywood Balcony Replacement

In a recent project, Bay Cities Construction rebuilt multiple balconies for a West Hollywood apartment complex.
Each balcony cost between $50,000 and $60,000 including waterproofing, new handrails, and sliding doors. The work involved deep rot removal, scaffolding, and compliance with SB-326 and SB-721 inspection requirements.
