Balcony Repair Contractor in Los Angeles
Permitted. Waterproofed. Documented.
RetroCal repairs wood-framed balconies, walkways, stairs, and guardrails on multifamily apartment buildings throughout Los Angeles. We work from existing SB 721 inspection reports and Los Angeles Housing Department E3 findings — dry rot, failed waterproofing, unsafe guardrails, or any other condition that requires a repair — and coordinate the repair details, permitting, framing repairs, waterproofing, guardrails, city inspections and closeout. RetroCal is a California licensed General Building Contractor experienced with retrofitting multifamily apartment buildings in Los Angeles.
What we repair on LA balconies
Rotted joists, ledgers, posts, and connection hardware replaced to current CBC standards with permit-approved structural details.
Full Pli-Dek and equivalent deck-coating systems, flashing, and drip-edge details. Permitted and inspected. Read our balcony waterproofing guide for Los Angeles apartments.
Code-compliant guardrail replacement — 42" height, 4" sphere rule, load-tested attachment.
We perform the corrective work identified in the inspection report under permit and assemble the repair documentation for submission to the applicable local agency.
Why LA balcony repair is different
Los Angeles has three things working against wood-framed balconies at once: marine-layer moisture, aging 1960s–1980s multifamily stock, and one of the most active building-department enforcement environments in California (LADBS, plus city departments in Beverly Hills, Santa Monica, West Hollywood, Pasadena, Burbank, and Glendale). Repairs done without permits or without documented waterproofing details won't satisfy §17973, and under §17973(i)(2) a civil penalty of $100–$500 per day, set by the local enforcement agency, applies where required repairs remain incomplete after the statute's repair and notice sequence.
Our LA repair process
- 1Scope from your inspection reportWe work directly from the SB 721 EEE report — ours or another firm's — so nothing gets missed.
- 2Repair details & permit submittalWe coordinate the permit-ready repair details, submit them to your local building department and respond to plan-check corrections.
- 3Tenant Habitability Plan (THP) & tenant notificationsWhere the City requires one for work on occupied rental units, we prepare the Tenant Habitability Plan (THP) for the Los Angeles Housing Department, submit it for approval and coordinate the required tenant notifications before work begins.

Get a Los Angeles Balcony Repair Estimate
Upload your existing inspection report with your request, or send the property address if you don't have a report yet. We review reports from any qualified inspector, including reports prepared in response to a Los Angeles Housing Department E3 notice, and come back with a scoped repair proposal and a schedule for your property. See what an inspection report should include.
Your estimate arrives by email, with optional work items you can add to the base contract and approve online. Once the work begins, your private project page lets you follow its live status and access the project documents. Permit timing depends on the building department, the plan-check turnaround and how much repair detail the findings require, so we schedule your specific property rather than quote a published average.
