“Payment schedules in California are governed by the Home Improvement Contract law (Business & Professions Code 7159). Contractors cannot legally require more than 10% of the contract price or $1,000 (whichever is less) as a down payment on home improvement projects. Any contractor asking for 30–50% down before starting work is either uninformed about California law or using cash flow from your project to fund another.”
Specify a 'substantial completion' date and a daily liquidated damages rate in your construction contract. Liquidated damages ($500–1,500/day is typical for residential) create a financial incentive for the contractor to stay on schedule. Without this provision, schedule delays have no contractual consequence for the contractor.
This ground-up new construction in Granada Hills replaced a condemned 1950s bungalow with a custom 2,800-square-foot modern farmhouse. The homeowners wanted a 4-bedroom, 3-bathroom home with an open-concept main floor, home office, and attached 2-car garage — all designed for energy efficiency and future solar installation.
NP Line Design managed the project from demolition of the existing structure through final certificate of occupancy. The foundation is a post-tensioned slab on grade with 4-inch turned-down edges, engineered for the site's expansive clay soil. Framing is conventional 2x6 walls at 16-inch spacing with engineered roof trusses.
The home includes a gourmet kitchen with a 10-foot island, Thermador appliance package, custom shaker cabinetry, and honed quartzite countertops. The master suite occupies the entire rear wing with vaulted ceilings, walk-in closet, and a spa-style bathroom with freestanding tub and frameless glass shower.
Energy systems include a 4-ton Daikin heat pump with variable-speed compressor, tankless water heater, R-21 wall insulation, R-49 ceiling insulation, and dual-pane low-E windows throughout. The roof is pre-wired for a 7.5 kW solar PV system with conduit and junction boxes installed per Title 24's solar-ready requirements. Smart home wiring includes CAT6 in every room, pre-wire for security cameras, and a structured wiring panel in the garage. LADBS permit and plan check for new construction took 14 weeks.
The existing property had an unpermitted rear addition that appeared on the city's records as an open code violation case. Before LADBS would issue a demolition permit for the old structure or a building permit for the new home, the code case had to be formally resolved — a bureaucratic process that can stall projects for months if not handled correctly. This required a hearing with LADBS, documentation of the demolition plan, and written confirmation that the violation would be eliminated. Additionally, the soils report revealed expansive clay at shallow depth, requiring a post-tensioned slab rather than standard spread footings — a more expensive foundation system that many homeowners do not anticipate.
NP Line Design's permit team resolved the code violation by preparing a complete package for the LADBS hearing: demolition plan, new construction drawings, and a timeline showing the unpermitted structure would be entirely demolished before new construction began. The hearing officer closed the case within 3 weeks, clearing the path for permits. For the foundation, the post-tensioned slab was designed by a structural engineer specializing in expansive soils, with cable spacing calculated from the geotechnical report's swell pressure data. The slab design added $15,000 versus standard footings but eliminated all future differential settlement risk — a worthwhile investment for a custom home.
