  "articleBody": "Industry practice guides and Los Angeles-area contractor process descriptions show that a room addition typically moves through **five main phases**: initial feasibility, design, permitting, construction, and inspections/close-out. 1. **Feasibility and budgeting**: This stage involves site visits, discussing goals, and rough cost ranges. Contractors and design-build firms in Los Angeles commonly emphasize checking zoning constraints, setbacks, and existing structure conditions early to avoid redesign later. 2. **Design and engineering**: The homeowner works with an architect, designer, or design-build contractor to produce floor plans, elevations, and structural plans. In Los Angeles’ seismic environment, a licensed structural engineer often designs foundations, framing, and lateral systems. Industry associations note that this phase can take several weeks to months depending on complexity and homeowner decision-making. 3. **Permitting and plan check**: The plans are submitted to the relevant building department (city or county) for plan check. LADBS and other local agencies advise that plan check timelines can range from a few weeks to several months, especially when resubmittals are needed to address corrections. 4. **Construction**: For a typical single-story room addition, local contractor schedules commonly estimate **3–6 months**, with longer durations for complex or second-story additions. Progress depends on inspections, change orders, and material availability. 5. **Inspections and final approval**: Building departments conduct **multiple inspections** (foundation, framing, rough electrical/plumbing/mechanical, insulation, and final). The project is complete when a final inspection is passed and the permit is signed off; for larger additions, some jurisdictions issue a revised certificate of occupancy. Construction management literature stresses the importance of a written schedule, clear change-order procedures, and contingency time to account for weather, inspection delays, and unforeseen existing-condition issues uncovered during demolition.",
