Pool & Spa Remodeling in Lake Forest
New pools, spa additions, replastering, tile and coping, and full pool remodels. Designed, permitted and built by our own crews.
Pool & Spa Remodeling 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.
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.
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.
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.
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.
New pool construction
$70,000 to $150,000+
What moves it: size and shape, spa, water and fire features, decking material, automation, and how much access and grading the site needs
Pool remodel and resurfacing
$15,000 to $45,000
What moves it: finish choice (plaster versus pebble or quartz), tile and coping replacement, new equipment, and whether the deck is being replaced at the same time
Paver patio and hardscape
from about $13,000
What moves it: square footage, paver type, base preparation, drainage, and any steps or retaining involved
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.

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 pool or spa project cost in Lake Forest?
New pool construction: generally $70,000 to $150,000+ across Southern California. What moves it is size and shape, spa, water and fire features, decking material, automation, and how much access and grading the site needs. We give line-item pricing after seeing the site rather than quoting a number over the phone.
How long does a pool remodel take?
A straightforward replaster with new tile and coping usually runs three to five weeks. A full remodel that includes new decking, equipment and features typically runs eight to twelve weeks. Site access and permit timing are the two things that move that most.
How long does a new pool take to build?
Most new pool builds run about three to five months from permit to first swim. Hillside sites that need engineered retaining or difficult access sit at the longer end of that range.
Should I replaster or fully remodel?
If the shell and plumbing are sound and you only dislike the surface, replastering with new tile and coping is the efficient choice. If the equipment is aging, the deck is cracked or the shape no longer suits how you use the yard, a full remodel costs less than doing it in two separate phases.
Do you self-perform the work?
Yes. Our own crews handle the build rather than passing it to a rotating set of subs, which is why the schedule and the finish standard stay consistent.
