“The most important document in any construction project isn't the permit — it's the contract. A vague contract with a scope defined as 'as per plans' is not sufficient protection for a homeowner. The contract should specify: payment schedule tied to milestones, allowances for specified items, exclusions list, change order threshold, and dispute resolution process.”
Always ask for a contractor's license verification at CSLB.ca.gov before signing any contract. A B-General Building Contractor license covers structural work; specialty work (electrical, plumbing, HVAC, roofing) requires separate C-license contractors on the team. Verify that any subcontractors on your project also have current CSLB licenses.

Yes, for walls over 3 feet in height. LADBS requires: building permit, structural engineering calculations, and drainage plan. Walls in hillside areas face additional review under the Hillside Ordinance. Walls over 6 feet require enhanced setbacks. Retaining walls must include proper drainage (weep holes, drainage gravel) to prevent hydrostatic pressure buildup.
Shotcrete walls are most popular for LA hillsides due to: conformability to irregular slopes, fast construction, good structural capacity, and ability to incorporate waterproofing. Soldier pile and lagging is preferred for tall walls (over 10 feet) or where excavation must be shored before wall construction. CMU is cost-effective for walls under 6 feet on accessible sites.
Properly engineered and drained retaining walls last 50-100+ years. Key failure factors in LA: inadequate drainage (hydrostatic pressure is the leading cause of failure), poor soil compaction behind the wall, undersized design for actual loads, and tree root damage. Annual inspection and drainage maintenance extends wall life significantly.
