Backyard & Outdoor Living built for Lake Forest properties

Many of Lake Forest's residential rules are written planned community by planned community, from El Toro and Lake Forest to Foothill Ranch and Portola Hills, each with its own setbacks and minimum lot sizes. Near the lake, Planning Areas 12 and 19 of the Lake Forest planned community allow zero side and rear setbacks, while the city's R1 district generally asks for 5 feet at the side and 25 at the rear. Three state-mapped liquefaction zones run along El Toro Road, Serrano Creek and Borrego Canyon Wash, and liquefaction heads the city's minimum requirements for a soils report. The General Plan places most of Foothill Ranch and Portola Hills in a Very High Fire Hazard Severity Zone, and its fire-safe design policy points to fire-resistant building and site design, materials and landscaping there, so decking, patio covers and outdoor kitchen finishes deserve early thought. The Municipal Code also gives eucalyptus trees a chapter of their own, covering their conversion, maintenance and removal.

Minimum lot sizes vary by zoning district and planned community: 7,200 square feet in the city's R1 district, 5,000 square feet in the Lake Forest and Rancho Serrano planned communities, 3,000 square feet for conventional detached lots in Foothill Ranch and Portola Hills, and one acre for Portola Hills rural estate lots. In Portola Hills, an attached or detached covered patio must sit at least 3 feet from a property line, or 8 feet from the street side of a corner lot.

We are a design-build team, which means the people who draw your project are the people who build it. Design, engineering, permits and construction run through one project manager and our own crews, so nothing gets lost in a handoff between a salesperson and a subcontractor. We are licensed, bonded and insured, CSLB license #1119054.

Permits in Lake Forest: Lake Forest's Building and Safety Division issues building permits, and pools and spas go on the city's Combination Pool/Spa Permit, with permit applications and building inspections requested through the eLakeForest portal. That application states that all bodies of water deeper than 18 inches must be fenced in accordance with state law and city ordinance. The city's Approvals Referral Sheet asks whether a site has slopes steeper than 5 percent or cut or fill exceeding 50 cubic yards or 3 feet in depth, and the Engineering Division can require a grading permit and pad certification before any building permit is issued. ADUs need both an ADU permit and a building permit unless the unit is created within existing or proposed single-family space, and every ADU and JADU must apply for its own address. Newly built detached and attached ADUs also need separately metered gas and electric service.

Permit details checked September 2026 against City of Lake Forest. Rules change, so we confirm them again for your parcel.

Local Conditions

What building in Lake Forest actually involves

Every city in Southern California builds differently. These are the things that change the scope, the schedule or the budget on Lake Forest projects.

01

Three liquefaction zones mapped by the California Department of Conservation run roughly parallel through the city along El Toro Road, Serrano Creek and Borrego Canyon Wash, with residential the largest land use inside them, and the General Plan calls for site-specific studies in areas potentially subject to liquefaction.

02

Where a soils report is required, the city's minimum requirements cover liquefaction, soil specifications, allowable bearing value and, for work on a sloped area, slope stability, and the report must be signed or wet stamped by the geotechnical engineer.

03

The General Plan places most of Foothill Ranch and Portola Hills, along with the Whiting Ranch Wilderness Park, in a Very High Fire Hazard Severity Zone, and it calls for defensible space, fuel modification and fire-retardant landscaping through Orange County Fire Authority review for new development in or next to high wildfire risk areas.

04

Only small areas of the city fall within FEMA 100-year or 500-year flood zones, along Aliso Creek, Serrano Creek, Borrego Canyon Wash, San Diego Creek and the lakes, and the General Plan notes those areas are largely undeveloped.

Investment

What this costs in Lake Forest

Real Southern California ranges, not a teaser number. Every project is priced line by line after we have seen the site.

Full backyard transformation

$50,000 to $250,000+

What moves it: how much hardscape is involved, whether a pool or outdoor kitchen is included, grading and retaining, and the level of lighting and planting

Paver patio and hardscape

from about $13,000

What moves it: square footage, paver type, base preparation, drainage, and any steps or retaining involved

Outdoor kitchen and BBQ island

$10,000 to $50,000+

What moves it: counter length, appliance package, countertop material, and whether gas, water and power need to be run a long distance

Pergola and shade structure

from about $9,500

What moves it: span, material (wood, aluminum or louvered), footing requirements, and integrated lighting or heating

Artificial turf

from about $9,900

What moves it: area, turf grade, base depth, drainage, and any pet-specific infill

Your number depends on your lot, your access and your finishes. We walk the site, then price every line so you can see exactly where the budget goes.

How We Build

Your Lake Forest project, step by step

01

Site Review

We measure the yard, check drainage and grade, and find the constraints before design starts.

02

Design & 3D

You walk the whole yard in 3D, so layout and materials are settled before we build.

03

Plans & Permits

Structures, walls and electrical get drawn and permitted where the work requires it. In Lake Forest that submittal goes to City of Lake Forest Community Development Department, Building and Safety Division.

04

Demo & Grading

Old surfaces come out, levels are set and drainage is corrected properly.

05

Build

Hardscape, structures, kitchen, features and lighting go in, sequenced by our own crews.

06

Planting & Handover

Planting, turf and final detail, then a full walkthrough of the finished yard.

Lake Forest Questions

Common questions from Lake Forest homeowners

Who issues the permits for this work in Lake Forest?

City of Lake Forest Community Development Department, Building and Safety Division. Lake Forest's Building and Safety Division issues building permits, and pools and spas go on the city's Combination Pool/Spa Permit, with permit applications and building inspections requested through the eLakeForest portal. That application states that all bodies of water deeper than 18 inches must be fenced in accordance with state law and city ordinance. The city's Approvals Referral Sheet asks whether a site has slopes steeper than 5 percent or cut or fill exceeding 50 cubic yards or 3 feet in depth, and the Engineering Division can require a grading permit and pad certification before any building permit is issued. ADUs need both an ADU permit and a building permit unless the unit is created within existing or proposed single-family space, and every ADU and JADU must apply for its own address. Newly built detached and attached ADUs also need separately metered gas and electric service. We prepare the drawings, make the submittal and handle plan-check corrections ourselves, so you are not the one chasing plan check.

What makes building in Lake Forest different?

Minimum lot sizes vary by zoning district and planned community: 7,200 square feet in the city's R1 district, 5,000 square feet in the Lake Forest and Rancho Serrano planned communities, 3,000 square feet for conventional detached lots in Foothill Ranch and Portola Hills, and one acre for Portola Hills rural estate lots. In Portola Hills, an attached or detached covered patio must sit at least 3 feet from a property line, or 8 feet from the street side of a corner lot. One local condition that shapes the work: Three liquefaction zones mapped by the California Department of Conservation run roughly parallel through the city along El Toro Road, Serrano Creek and Borrego Canyon Wash, with residential the largest land use inside them, and the General Plan calls for site-specific studies in areas potentially subject to liquefaction.

Which parts of Lake Forest do you work in?

All of it, including Foothill Ranch, Portola Hills, Baker Ranch and Serrano Highlands. Our crews run every job out of our Cahuenga Pass base in Los Angeles, with our own people on site.

What does a backyard or outdoor living project cost in Lake Forest?

Full backyard transformation: generally $50,000 to $250,000+ across Southern California. What moves it is how much hardscape is involved, whether a pool or outdoor kitchen is included, grading and retaining, and the level of lighting and planting. We give line-item pricing after seeing the site rather than quoting a number over the phone.

How long does a backyard remodel take?

A patio and turf refresh often finishes in three to five weeks. A full transformation with hardscape, an outdoor kitchen, structures and lighting typically runs ten to sixteen weeks, and longer if a pool is part of the same phase.

Pavers or poured concrete?

Pavers cost more up front but flex with ground movement instead of cracking, and individual units can be lifted and replaced. Poured concrete is cheaper initially, but a crack means cutting out and repouring a section that rarely matches. On most Southern California soil we recommend pavers for anything you will look at every day.

Can you fix drainage at the same time?

Yes, and on most projects we insist on it. Correcting grade and adding proper drainage while the yard is already open is far cheaper than retrofitting it after new hardscape is down.

Do you handle the whole yard in one project?

Yes. Design, permits, hardscape, structures, kitchen, lighting and planting run through one team and one project manager, so nothing gets lost between trades.
