Direct answer
Yes. Existing homes can often be automated without a full renovation, but pathways and desired features determine how invasive the work will be. Retrofit-friendly controls, wireless sensors, battery-powered shades, existing Ethernet or coax, attic access, crawlspaces, closets, and carefully selected equipment locations can reduce wall work.
Some objectives still benefit from new cable. Wired access points, PoE cameras, centralized equipment, shade power, and high-performance audio or video distribution may require targeted routes and drywall access. Before recommending products, inspect electrical boxes, neutral conductors, network wiring, HVAC controls, equipment locations, and construction materials. The proposal should identify likely access openings and responsibility for repair. A retrofit can be highly capable, but promising a completely wireless or zero-drywall solution before inspection is not credible.
