Los Angeles’s climate makes outdoor living one of the highest-value home improvements in the region — a well-designed patio or deck is used year-round and adds functional square footage that’s only possible in Southern California. Patio and deck additions in LA range from basic concrete slabs at $15/sq ft to premium travertine or wood deck installations at $85+/sq ft. This guide covers the real costs of patio and deck additions in Los Angeles in 2026.
What you get: Broom-finish or smooth concrete slab, 3.5″ thick with wire mesh reinforcement. Expansion joints. Proper slope for drainage. For a 400 sq ft patio: $3,200–$7,200. The most affordable patio option in Los Angeles — durable, low maintenance, permits typically not required for slabs under 200 sq ft not attached to the home.
What you get: Interlocking concrete or natural stone pavers on a compacted base with polymeric sand joints. For a 400 sq ft patio: $7,200–$14,000. Pavers offer superior aesthetics, easy repair, and the ability to match the home’s design vocabulary. Popular in Sherman Oaks, Encino, Pasadena, and the Valley.
What you get: Natural travertine, slate, or quartzite pavers on a mortar bed. For a 400 sq ft patio: $14,000–$26,000. Travertine stays cool underfoot (important in LA summers), looks genuinely premium, and matches the architectural vocabulary of Mediterranean, Spanish, and contemporary LA homes. Popular in Brentwood, Pacific Palisades, Woodland Hills, and Encino.
What you get: Elevated wood or composite deck on framed structure. For a 350 sq ft deck: $14,000–$29,750. Wood decks require a building permit in Los Angeles (elevated structure). Popular for hillside properties where the ground level is uneven and a framed deck creates usable outdoor space that would otherwise be on a slope. Composite decking (Trex, TimberTech) at the higher end offers low maintenance and 25+ year life.
What you get: Covered patio structure (aluminum patio cover, wood pergola, or solid-roof addition) with outdoor kitchen, built-in seating, fire feature, and lighting. A fully equipped outdoor living room in LA’s climate adds functional year-round space that rivals interior living area in value. Requires building permit. Popular in the San Fernando Valley, South Bay, and Pasadena.
Concrete patio: $3,200–$7,200 for 400 sq ft. Concrete pavers: $7,200–$14,000 for 400 sq ft. Natural stone (travertine): $14,000–$26,000 for 400 sq ft. Covered outdoor living room: $25,000–$85,000. LA’s competitive outdoor living market makes patio additions one of the best ROI investments in the region.
Ground-level concrete slabs under 200 sq ft and not attached to the home generally do not require permits. Larger slabs, pavers, elevated decks (any height), covered patio structures, and outdoor kitchens with gas connections all require LADBS permits. APLA evaluates permit requirements for every patio project.
Concrete slab (no permit): 1–2 weeks. Pavers (no permit): 2–3 weeks. Natural stone (no permit): 2–4 weeks. Elevated deck (with permit): 6–14 weeks including LADBS permit. Covered outdoor room (with permit): 10–20 weeks.
