After six decades of building pools across California, the team at Century Pools has seen the same pattern repeat itself: homeowners walk in excited about how their pool will look, but they rarely ask about what will make it last.
The shape. The features. The finishes.
Those are the conversations most people want to have. But the success of your pool comes down to something far less glamorous—the fundamentals you can’t see.
Site evaluation. Structural support. Drainage and plumbing. Long-term maintenance planning.
These invisible details determine whether your pool becomes a treasured gathering place or a costly headache. Understanding them before you break ground can save you from delays, budget overruns, and regrets that surface years after construction.
The Hidden Cost of Skipping the Planning Phase
Most homeowners don’t realize how much can go wrong when you rush into construction without proper planning.
Century Pools once took over a project where the original contractor focused almost entirely on aesthetics. Amazing features. Dramatic shapes. On paper, the pool looked incredible.
But the fundamentals were ignored.
The site wasn’t graded properly. The plumbing had uneven slopes. The structural reinforcement wasn’t consistent. Within months, the homeowners started seeing cracks and water circulation problems.
The team had to carefully address the foundational issues—regrading, fixing plumbing slopes, reinforcing the structure—before they could complete the design features. What should have been a straightforward project became a costly repair job.
Budget overruns are common when homeowners underestimate costs associated with permits, excavation, landscaping, fencing, and pool maintenance equipment. According to the California Pool Association, experts recommend including a contingency fund of at least 10-15% to cover unforeseen expenses.
That $50,000 quote often doesn’t account for site challenges that emerge during construction.
How to Identify a Contractor Who Understands the Fundamentals
When you’re sitting across from a contractor for the first time, you probably don’t know to ask about plumbing slopes or structural reinforcement.
But those are the questions that reveal whether someone actually understands pool construction—or if they’re just good at selling a beautiful design.
The right questions dig into fundamentals:
- How do you handle site grading and drainage?
- Can you explain your approach to structural reinforcement?
- How do you ensure the plumbing slopes are correct for proper circulation?
A knowledgeable contractor will walk through these details clearly and confidently. They’ll show you they understand the engineering behind the pool—not just how it will look.
Here’s what a credible answer sounds like:
“We evaluate the slope of your backyard, direct water away from the pool, and ensure proper runoff so the pool and surrounding areas stay safe and structurally sound. Let me walk you through the site and show you how grading affects the final layout.”
Compare that to a red flag response:
“Don’t worry, we’ve done this hundreds of times.”
Vague reassurances without explanation or visuals often indicate the contractor is more focused on closing the sale than building something that lasts.
According to industry experts, hiring inexperienced or unqualified pool builders can result in poor workmanship, significant delays, and legal issues. The cheapest bid isn’t always the best.
Navigating California’s Permit and Regulatory Requirements
Permits and regulations are another area homeowners consistently underestimate.
One family assumed they could skip the permitting process to save time. They started construction without proper approvals. Halfway through the project, the city issued a stop-work order.
They had to pay fines. Parts of the pool construction had to be redone to meet code. The project was delayed by months, and costs ballooned far beyond the original budget.
If you miss a step in the permit process, it could delay your project, incur additional costs, or even result in fines. In some documented cases, homeowners faced the need to dismantle portions of their pool to meet compliance requirements.
What the Permit Process Actually Looks Like
Once you sign with a contractor, they should immediately begin submitting detailed plans to the city. This includes engineering drawings, site grading, plumbing layouts, and safety features.
The timeline varies, but typically takes a few weeks to a couple of months depending on the city’s review schedule.
Common hold-ups happen when:
- Additional documentation is requested for structural or drainage clarifications
- Inspectors have questions about setbacks, fencing, or safety requirements
- Plans don’t account for California’s specific regulations
In most Bay Area counties, permit approvals currently take at least one month after submittal for the first review, with another six weeks possible before the actual permit is issued. This timeline has lengthened significantly in recent years.
A reputable contractor guides you through each step, making sure everything is compliant before construction begins. Handling permits properly upfront ensures your pool is legal, safe, and avoids costly delays later.
💡 Important: Most California jurisdictions require pools to be set back a minimum distance from property lines, typically between 5 and 10 feet. In no case should a swimming pool be located within three feet of a property line, building, or other structure.
Design Decisions You’ll Regret (And How to Avoid Them)
Homeowners focus heavily on aesthetics during the planning phase. But some design choices that look incredible in photos become problems a year or two after construction.
Oversized Water Features
Dramatic waterfalls and elaborate water features are showstoppers. They look amazing on Instagram.
But many families realize later that these features add significant maintenance, increase water and chemical use, and can limit usable space around the pool.
The key is balancing aesthetics with functionality. How does a feature fit into your lifestyle long-term? Will you still want to maintain it five years from now?
You want a pool that’s beautiful and practical—not just impressive in pictures.
Pool Size and Placement Mistakes
Most people think bigger is better. Or they choose a location based purely on the view.
But in pool construction, you have to balance size and placement with practicality.
A pool that’s too big for your yard can:
- Limit landscaping and seating areas
- Reduce safety zones
- Dominate the entire backyard
- Restrict space for other outdoor activities
Industry experts recommend that pools should take up no more than 25% of your backyard space. This ensures there’s room for lounge chairs, dining areas, and other outdoor features.
One of the biggest regrets homeowners report is building a pool that dominates their entire yard, leaving no space for anything else.
Placement also affects sunlight, drainage, and how the pool interacts with the rest of your backyard. Poor placement creates long-term usability issues—like a pool that gets no sun, blocks a beautiful view, or sits too far from the house.
You should consider daily use, access for construction, and long-term maintenance when deciding size and location. The goal is a pool that looks great and fits seamlessly into your lifestyle for decades.
Understanding Site Evaluation and Topography
One of the most frequent errors homeowners make is rushing into construction without a thorough site evaluation.
This critical step identifies potential issues like soil stability, underground utilities, water runoff, and adequate construction space. Skipping it can result in major structural problems down the road.
Topography is the top affordability factor for California homeowners considering a new pool. Slopes and hillsides often require extra engineering, retaining walls, and other safety measures to ensure the pool and land around it don’t shift.
These aren’t optional expenses. They’re necessary investments in the structural integrity of your pool.
⚠️ Warning: Building too close to your house can create problems ranging from water damage to foundation issues. Always consult with an architect or engineer before starting construction to determine the best location.
What Happens During the Construction Timeline
Understanding what happens during each phase helps you set realistic expectations.
From excavation to the final pebble finish, pool construction involves multiple stages, each with its own timeline and potential delays.
Weather affects schedules. So do inspections. Material availability can push timelines back.
A reputable contractor will walk you through each phase and explain what could impact the schedule. They’ll keep you informed as the project progresses, not leave you guessing about when your pool will be ready.
The gunite shell forms the foundation of your pool. The pebble finish coats the gunite, creating the interior surface you’ll see and touch every day. Features like a Cabo shelf—the long, elongated step with shallow depth that can accommodate a chair—get integrated during construction.
Each element requires proper timing, curing, and inspection.
The Long-Term Reality of Pool Ownership
Building a pool isn’t just about the construction phase. It’s about how ownership affects your property value, ongoing maintenance responsibilities, and family lifestyle for years to come.
Pools are treasured meeting places where memories are made, family events are held, and new beginnings are celebrated. But they also require regular maintenance, seasonal care, and occasional repairs.
You need to factor in:
- Weekly cleaning and chemical balancing
- Equipment maintenance and eventual replacement
- Seasonal opening and closing (if applicable)
- Energy costs for heating and filtration
- Insurance considerations
The homeowners who enjoy their pools most are the ones who understood these responsibilities before breaking ground.
Lessons from Six Decades of Pool Construction
Century Pools was founded by Brian O’Neal in 1964. He was a hard worker, often found with a shovel in hand, supporting his family and building a legacy.
Now his three sons—Michael, Patrick, and Casey—continue that legacy with the help of second-generation family members.
Being a multigenerational pool contractor isn’t just about longevity. It’s about building lasting relationships based on trust and shared dreams.
Over 60 years, construction standards have evolved. Homeowner expectations have changed. But the fundamentals remain the same.
Successful pool construction still hinges on:
- Thorough site evaluation and planning
- Understanding and following regulations
- Choosing a contractor who prioritizes engineering over aesthetics alone
- Making design decisions that balance beauty with functionality
- Preparing for the long-term realities of ownership
Each project is an opportunity to demonstrate commitment to excellence and earn trust. The goal is creating spaces that families cherish for generations—not just pools that look good in photos.
Before You Break Ground
Your pool should be more than a luxury. It should be a treasured gathering place that fits your lifestyle, meets safety requirements, and stands the test of time.
That starts with understanding what you’re getting into before the first shovel hits the ground.
Ask the right questions. Choose a contractor who prioritizes fundamentals. Plan for the long term.
The homeowners who do this work upfront are the ones who end up with pools they love—not just for the first summer, but for decades to come.
