A new gunite pool and spa in Woodland Hills costs $85,000 to $160,000. A small, simple pool on a flat lot with a modest deck can start near $65,000. A larger pool with a raised spa, a vanishing edge and 900 sq ft of paver decking exceeds $200,000. Woodland Hills is also the hottest corner of the San Fernando Valley, which changes equipment sizing, and it splits sharply between flat tracts near Warner Center and steep parcels climbing toward Mulholland. Both facts show up in the price.
Phase-by-Phase Construction Costs
A pool is built in about a dozen discrete phases. On a 16 by 34 foot pool with an attached spa, roughly 500 sq ft of water surface:
- Design, 3D presentation and construction drawings: $2,500-$8,000 - Structural and geotechnical engineering where required: $3,500-$9,000 - Layout and excavation, flat lot: $6,000-$14,000 - Steel reinforcement: $6,000-$11,000 - Rough plumbing: $8,000-$14,000 - Electrical, bonding and gas: $4,000-$8,000 - Gunite or shotcrete shell: $28,000-$45,000 - Tile and coping: $8,000-$16,000 - Equipment set with variable-speed pump, filter, heater and automation: $9,000-$18,000 - Decking, 700 sq ft in pavers at $18-$32 per sq ft: $12,600-$22,400 - Interior pebble finish: $12,000-$20,000 - Safety features, fencing or cover: $3,000-$12,000 - Start-up, water and chemical balancing: $1,200-$2,500
Permits and city fees add $3,000-$7,000.
What Each Upgrade Adds
Features are priced honestly as add-ons, not percentages.
- Raised spa with spillway: $18,000-$30,000 - Vanishing edge with catch basin, surge tank and second pump: $25,000-$60,000 - Baja shelf with umbrella sleeve and bubblers: $4,500-$9,000 - Swim-up bar seating: $6,000-$14,000 - Sheer descent water features: $1,800-$3,500 each - Fire bowls, gas plumbed with electronic ignition: $3,500-$7,000 each - Colour-changing LED lights: $900-$1,800 each - Full app-based automation with valve actuators: $3,500-$7,500 - Salt chlorine generator: $2,200-$4,000 - Upgrading from standard plaster to pebble or glass-bead finish: $6,000-$14,000
A Woodland Hills pool that reads as a resort build usually has a raised spa, a Baja shelf, two fire bowls and automation. That package is roughly $32,000-$55,000 over a plain rectangular pool, which is why the same footprint quotes so differently between builders.
Pro Tip
Decide on the vanishing edge before engineering. It changes the shell design, the plumbing and the deck elevations, and it cannot be added sensibly later.

Hillside Lots, Soils and Structural Support
South of Ventura Boulevard, Woodland Hills climbs toward Mulholland Drive, and lots there fall under the City of Los Angeles Baseline Hillside Ordinance (184,802), which governs grading quantities, export and building envelope. Practical consequences:
- Geotechnical soils report: $3,500-$6,500 - Structural engineering for a pool on or near a slope: $4,000-$9,000 - Caissons or grade beams supporting the shell: $15,000-$40,000 - Excavation and soil export from a restricted site: $15,000-$45,000 instead of $6,000-$14,000 - Retaining walls at $60-$150 per face foot
Much of the Valley floor here sits on alluvial and expansive soils. Expansive clay under a deck causes lifting and cracking, so budget for proper base: a minimum 4 inches of compacted Class II base under patio pavers and 6-8 inches under any vehicle surface, with the subgrade compacted to spec. Skipping base preparation is the most common reason a two-year-old pool deck looks ten.
Sizing Equipment for Woodland Hills Heat
Woodland Hills regularly records the highest temperatures in the Valley, often above 105°F in summer. That has two cost effects.
First, evaporation. An uncovered pool here loses meaningful water volume through summer, so automatic fill valves at $600-$1,200 installed and a cover to slow evaporation are practical, not luxury. A powered safety cover at $12,000-$22,000 doubles as a required safety feature under California's pool safety law.
Second, heating and shade. Because ambient temperatures are high, a heat pump at $6,500-$11,000 installed often outperforms gas for shoulder-season swimming, though a 400,000 BTU gas heater at $4,000-$6,500 heats a spa far faster. Many Woodland Hills builds use both. Solar pool heating panels at $5,000-$9,000 are a strong fit here given roof exposure and sun hours.
Shade over the deck matters too. Unshaded pavers or concrete on a west-facing yard become unusable by mid-afternoon.
Permits and Realistic Build Duration
Woodland Hills is within the City of Los Angeles, so a private pool is permitted through LADBS on a combined Building-Mechanical permit. Plumbing plan check applies to commercial and apartment pools rather than single-family homes. Hillside lots add a grading permit and, in some cases, geology review.
Construction duration for a flat-lot pool in Woodland Hills is typically 10-16 weeks from excavation to start-up, assuming inspections land on schedule. Add 4-8 weeks for hillside builds with caissons, engineered walls and export. Plaster is followed by roughly four weeks of daily brushing and chemical balancing before the water is stable.
The honest order of operations is design, soils, engineering, plan check, then construction. Homeowners who compress the front end usually pay for it in change orders once the excavator finds what the soils report would have told them.
Pro Tip
Ask any builder for their proposed base thickness and compaction spec in writing. It is a small line on the bid and the biggest predictor of how the deck looks in five years.
Final Thoughts
Budget $85,000-$160,000 for a new pool and spa in Woodland Hills, with $65,000 possible for a small simple build and $200,000-plus for a large pool with a vanishing edge. Hillside engineering, caissons and export are the main escalators. Get the soils report first, size heating for real Valley conditions, and pay for proper base under the deck.
Frequently Asked Questions
Between $85,000 and $160,000 for most builds. A small, simple pool with a modest deck can start near $65,000. A large pool with a raised spa, vanishing edge and extensive paver decking exceeds $200,000. Hillside lots requiring caissons and soil export typically add $30,000-$80,000 to an equivalent flat-lot build.
Between $25,000 and $60,000. The edge requires a catch basin, a surge tank, a second pump dedicated to the edge circulation, precise structural tolerance on the weir wall and usually additional engineering because the pool is typically positioned on a slope. It must be designed in from the start, not added later.
Lots near Mulholland fall under the Baseline Hillside Ordinance (184,802), which restricts grading and export. Add a geotechnical report at $3,500-$6,500, structural engineering at $4,000-$9,000, caissons or grade beams at $15,000-$40,000, and export costs that can triple the excavation line. Retaining walls run $60-$150 per face foot.
Ten to sixteen weeks of construction from excavation to start-up on a flat lot, and four to eight weeks longer on hillside sites with caissons and engineered walls. After plaster, allow about four weeks of daily brushing and chemical balancing before the water chemistry stabilises and normal use begins.
A combination usually works best. A 400,000 BTU gas heater at $4,000-$6,500 heats a spa quickly. A heat pump at $6,500-$11,000 is more efficient for extending pool season in a climate this warm. Solar panels at $5,000-$9,000 perform well here given sun hours and typical roof exposure.
