Bid language
Terms that affect this estimate
Use these definitions while comparing decks bids, because the same headline price can hide very different scope.
Fire Safety
WUI zone
WUI zones can affect roofing, siding, decks, vents, fences, landscaping, glazing, and defensible-space planning in California. Requirements vary by jurisdiction and fire severity zone.
Fire Safety
Defensible space
Defensible space affects landscaping, decks, siding, roofing, fences, and outdoor structures in California fire-prone areas. It does not mean a bare yard; it means thoughtful spacing, materials, maintenance, and ember-aware design.
Permits
Permit pull
A permit pull means a city or county has reviewed the project scope and issued permission to start work. Outdoor projects may need permits when they affect structures, utilities, drainage, gas, electrical, pools, ADUs, or fire-zone requirements.
Zoning
Setback
Setbacks shape where ADUs, pools, patio covers, decks, equipment pads, and outdoor kitchens can be placed. Rules vary by city, zoning district, fire access, easements, and project type.
Site Work
Slope drainage
Slope drainage matters in California yards because hillside runoff can damage patios, pavers, retaining walls, foundations, planting areas, and neighboring lots.
