Los Angeles Landscape Design & Build — MWELO-Compliant, Rebate-Stacked, Native-First
Landscape in Los Angeles in 2026 is not the same trade it was even five years ago. MWELO 2023 (the state's Model Water Efficient Landscape Ordinance, updated in 2023) sets a hard water-budget that every permitted landscape over 500 square feet has to hit. LADWP pays $3-to-$5 per square foot for fescue lawn removal under the turf-replacement rebate, and that money compounds with the smart-controller incentive, the drip-irrigation rebate, and the SoCal Water$mart graywater rebate if you tie it into a laundry-to-landscape line. RHCA architectural review locks down Hidden Hills and Bell Canyon; the California Coastal Commission concurrent-reviews everything in Manhattan, Hermosa, and Venice canal-side; HPOZ proximity matters in Hancock Park and Wilshire Park. The drought-aware Mediterranean and California-native palette is now the design baseline, not the exception — and the LADWP rebate paperwork pays a meaningful chunk of every project. NPLD has been doing architectural and landscape work in LA since 2016, full CSLB GC license since 2023, 200+ permitted LA builds on the board, and landscape is one of the 33 trades we run end-to-end. Fixed bid in 7 business days, all rebate paperwork filed, MWELO compliance certified. (818) 605-1388.
What LA landscape design and build actually costs in 2026
Refresh tier ($15K-$35K): existing irrigation reworked to drip on the planted zones, smart controller (Hunter Hydrawise or Rachio 3) installed and programmed, 800-1,500 sq ft of turf removed and replaced with drought palette and 3-inch mulch, basic hardscape repair, exterior lighting (8-12 path and uplight fixtures on a low-voltage transformer), three or four feature trees added or thinned. Done in 3-4 weeks on a Studio City flat lot last spring. Mid-tier full-yard ($35K-$85K): full front-and-back design on roughly 4,000 sq ft of planted area, 75% California-native or low-water Mediterranean palette, full drip system on weather-based smart controller, decomposed-granite or flagstone hardscape paths, raised planters or low retaining seat-walls, accent boulders, full landscape lighting design (18-30 fixtures, two zones), automatic gate and side-yard refresh. 6-9 weeks. Three Encino and Sherman Oaks full-yards in 2026. Premium 8,000 sq ft with hardscape ($85K-$180K): full design-build, dimensioned plans (we draw them in-house), engineered drainage (French drains, area drains, dry-well discharge — every LA property over 5,000 sq ft has drainage issues nobody saw until the first storm), board-formed concrete or natural-stone hardscape, custom outdoor lighting, fire pit or fire feature, vegetable garden or fruit-tree orchard, water feature (recirculating, MWELO-compliant), full smart irrigation. 10-14 weeks. Two Brentwood and one Hancock Park build at this tier in 2026. Luxury estate 15,000+ sq ft with pool-yard system ($180K-$450K): full estate landscape integrated with pool, pool house, outdoor kitchen, and pavilion structures. Includes structural retaining walls if the property is hillside (engineered, permitted), full drainage engineering with civil engineer's stamp, mature specimen trees (24-inch and 36-inch box for olives, oaks, palms — these run $3,500-$12,000 each installed), elaborate outdoor lighting with central automation, irrigation zoned to a 12-to-24-station controller, edible garden and orchard, vineyard or rose garden if desired, sport court grading if applicable. 16-32 weeks. Two completed in Holmby Hills and Mandeville Canyon in 2025-2026.
MWELO 2023 — the rule that decides whether your landscape gets approved
MWELO (Model Water Efficient Landscape Ordinance) applies to every landscape project over 500 square feet of new or modified planted area that requires a permit. The 2023 update tightened the water budget significantly: 55% of plants must be low-water or very-low-water (we typically run 75% native or Mediterranean to be safely under), the irrigation system must be drip or micro-spray on planted areas (no spray heads on plant zones — only on the remaining turf if any), the smart controller must be weather-based with a rain sensor, and the soil must be amended with at least 4 cubic yards of organic matter per 1,000 sq ft of planted area at install. At permit-pull time, your designer or contractor submits a MAWA (Maximum Applied Water Allowance) calculation and an ETWU (Estimated Total Water Use) calculation — ETWU must be at or under MAWA. We run the math on every bid and we file the MWELO certificate at closeout. The drought-palette design happens to also be the most beautiful approach to LA landscape today — Mediterranean and California-native palettes feel right in this climate in a way that East Coast lawn-and-hedges never did.
LADWP turf rebate + smart controller + drip stacking — the money the homeowner usually misses
LADWP turf-replacement rebate: $3 to $5 per square foot of removed fescue or other rebate-eligible lawn, replaced with low-water palette and 3-inch mulch with permeable surface or living plants. On a 1,500 sq ft removal that is $4,500-$7,500. LADWP smart controller rebate: $80-$120 per controller (Hunter Hydrawise, Rachio 3, or equivalent weather-based controllers qualify). LADWP rotating-nozzle or drip-conversion rebate: $0.20-$0.50 per square foot of irrigation converted from spray to drip. SoCal Water$mart graywater rebate: $250-$1,000 if you install a Laundry-to-Landscape graywater system serving the new planted area. LADWP rain-barrel and cistern rebate: $35-$100 per cistern, up to $750 per property. Total rebate stack on a typical 4,000 sq ft full-yard project: $5,500-$9,500 back to the homeowner, which we file on your behalf with the receipts and the pre-and-post photos. The non-NPLD landscape contractor will typically install the new system and hand you a piece of paper — we file the paperwork and you receive the LADWP check 8-12 weeks later.
RHCA, Coastal, and HPOZ — where landscape projects get reviewed before LADBS
RHCA architectural review (Hidden Hills and Bell Canyon): the Hidden Hills Community Association and the Bell Canyon Architectural Review Committee both require full landscape plan submittal with renderings, plant list, and neighbor notification before a city permit is even applied for. Review timeline runs 8-12 weeks with at least one revision cycle on most submissions. The board has strong opinions about palette (Mediterranean and equestrian-friendly preferred), tree-removal (a 24-inch oak is a hard no without mitigation), and lighting (low-light, downlit, no upward-facing fixtures over 6 feet). We have submitted four projects through Hidden Hills RHCA and three through Bell Canyon ARC and our approval rate is 100% first or second review. California Coastal Commission concurrent review (Manhattan/Hermosa Sand Section, Venice canal-side, Palisades bluff, Malibu): public-view corridor analysis, dune-stability letter if applicable, native-palette preference, no invasive species (ice plant, pampas grass, ivy are explicitly disallowed). HPOZ proximity review (Hancock Park, Wilshire Park, Whitley Heights, Spaulding Square): Cultural Heritage Commission concurrent review if landscape changes are visible from the public right-of-way and the property is contributing — typically triggered by front-yard hardscape changes, mature-tree removal, or fence-and-gate visibility changes; rarely triggered by back-yard work.
Drip + smart-controller architecture — how we set up an irrigation system that actually runs for 15 years
Every NPLD landscape install gets a weather-based smart controller (Hunter Hydrawise, Rachio 3, or Rain Bird ESP-TM2 with the LNK WiFi module), 12-to-24 zones depending on lot size, dedicated drip lines on every planted zone (Netafim or DIG drip with pressure-compensating emitters at 0.5 or 1.0 gallons per hour), inline pressure regulators on every zone (most LA water pressure runs 80-110 psi at the meter; drip needs 25-30 psi), a master valve and a flow sensor at the controller to catch leaks before they run for a week, and a rain sensor wired directly to the controller. Smart controllers pull weather data from local NOAA stations and adjust irrigation in real time — on a typical LA October week with an unexpected light rain, the controller skips two cycles automatically, which a non-smart timer would have run anyway. We program every controller to the plant palette we install, we leave you the app password, and we are available for tuning during the first growing season at no cost.
How we design and build a landscape — design-build under one company
Step one: free 90-minute on-site consult. We walk the property with the homeowner, we ask about how the family uses the yard (kids? dogs? entertaining? lap-swim? vegetable garden?), and we set the budget bracket honestly. Step two: we draw three concept-level palette directions (Mediterranean, California-native, Modern Tropical-leaning) and three site-plan options, no charge — most homeowners convert at the concept phase. Step three: fixed-bid in 7 business days from concept approval, line-itemed across plant material (species + container size + count), irrigation, hardscape, lighting, drainage, soil amendment, smart controller, rebate paperwork, MWELO certificate, and any RHCA or Coastal or HPOZ submittals. Step four: 10% deposit, contract logged with CSLB (license 1105249). Step five: one project lead, weekly Friday photo-update, MWELO closeout submittal, LADWP rebate paperwork filed within 10 days of completion, 2-year plant-establishment warranty (we replace any plant that fails to establish in the first 12 months free), 10-year warranty on irrigation and hardscape workmanship.
Frequently Asked Questions
Does my landscape project need an LADBS permit, and what triggers MWELO compliance?
Permit triggers: any new or modified planted area over 500 sq ft, any hardscape over 200 sq ft of impermeable surface, any retaining wall over 4 feet, any drainage modification, any irrigation point-of-connection change at the meter. MWELO compliance is required on every permitted landscape project over 500 sq ft. Pure plant-replacement on existing irrigation under 500 sq ft is usually permit-free. We tell you on day one which category your project falls into.
How much LADWP rebate money will I actually get back, and how long does it take?
On a typical 4,000 sq ft full-yard project with 1,500-2,500 sq ft of fescue removal: $5,500-$9,500 back stacked across turf, smart controller, and drip conversion rebates. LADWP processing time runs 8-12 weeks from completion. We file all paperwork including receipts, before-and-after photos, plant counts, and irrigation schedules on your behalf within 10 days of project closeout.
What is the difference between Mediterranean and California-native palettes, and which is better for my yard?
Mediterranean palette draws from olive, rosemary, lavender, sage, citrus, bougainvillea, agave, and the broader Mediterranean basin — it is the most-loved palette in LA for a reason, and it qualifies under MWELO at 55%+ low-water classification. California-native palette focuses strictly on plants native to the California floristic province — coast live oak, toyon, manzanita, ceanothus, white sage, deergrass, monkeyflower — and it is the most ecologically supportive palette for local pollinators and wildlife. We typically blend: 50-60% California native for ecological function and 25-35% Mediterranean for showcase color and edibles. Both fully qualify for MWELO compliance and LADWP rebates.
Hidden Hills and Bell Canyon — does RHCA architectural review actually slow this down by months?
Yes. Hidden Hills RHCA and Bell Canyon ARC each require full landscape plan submittal with renderings, plant list, lighting plan, and neighbor notification before the city permit is filed. Review runs 8-12 weeks with at least one revision cycle on most projects. Both boards have strong palette and lighting preferences and we know them. We design to those preferences from day one to minimize revision cycles.
Can I keep some lawn for the kids, or does MWELO force me to remove all turf?
You can keep functional turf. MWELO requires 55%+ of the planted area to be classified low or very-low water — that means up to 45% can be moderate or high water use, including lawn. We typically size functional play-lawn at 400-1,200 sq ft, irrigated separately on a high-efficiency rotor zone (not on drip — turf needs rotor heads), and keep the rest of the yard at native and Mediterranean palette. The kid-friendly small lawn stays.
What is your warranty on plants and on irrigation?
Plant establishment warranty: we replace any plant that fails to establish in the first 12 months free of charge, full size for size. Irrigation workmanship warranty: 10 years on installation, parts and labor on the system we install. Smart controller manufacturer warranty (Hunter, Rachio, Rain Bird) passes through to you. Hardscape: 10 years on workmanship for board-formed concrete, dry-laid flagstone, decomposed granite paths, and retaining walls under 4 feet.
Do you do the drainage engineering, or do you sub it to a civil engineer?
On luxury and estate-tier projects with significant grade change or known drainage issues, we coordinate with a licensed civil engineer for a stamped drainage plan (cost line-itemed in your bid, typically $3,500-$8,500). On refresh and mid-tier projects, our in-house team handles drainage design — French drains, area drains, dry-well discharge — which is sufficient for the vast majority of LA flat-lot situations.
How long does an LA full-yard landscape build actually take?
Refresh: 3-4 weeks. Mid-tier 4,000 sq ft full-yard: 6-9 weeks. Premium 8,000 sq ft with hardscape: 10-14 weeks. Estate 15,000+ sq ft with retaining and structural work: 16-32 weeks. Add 8-12 weeks if you are in Hidden Hills or Bell Canyon (RHCA) or if you need Coastal Commission review.
Do you handle the LADBS permit, the MWELO certificate, the RHCA submittal, and the rebate paperwork — or is that on me?
All of it is on us. LADBS permit pull and inspections, MWELO MAWA/ETWU calculations and closeout certificate, RHCA or ARC or Coastal submittals where applicable, HPOZ submittal where applicable, and the entire LADWP and SoCal Water$mart rebate filing package with photos and receipts. You sign the homeowner forms; we do the rest.
Can I phase the landscape over two or three years to spread the cost?
Yes. Most premium and estate landscapes phase: Year 1 = irrigation infrastructure, hardscape, mature specimen trees, and front-yard finish. Year 2 = back-yard finish, planting infill, and outdoor lighting. Year 3 = vegetable garden, water feature, or fire feature. We design the full plan in Year 1 so the irrigation and grading are right for the eventual full build, then we phase the visible work to your budget.
