All homeowners in Los Angeles have dreams of improving their property. Whether that’s an awesome kitchen remodel, an ADU, or building a custom dream home, the possibilities are endless. The question that typically follows is, “How long will this take?” It can seem like a maze when trying to get a straightforward answer. The realistic construction timeline Los Angeles offers is more than the physical build; design, permitting, and a bunch of LA-specific factors come into play.
This article will take away the confusion and provide you with a phase-by-phase description of what to expect on your next project. We’ll show you everything that happens at every stage; from the first drawings you get to final inspections, you can make sense of it all.
Before getting into the specifics, let’s talk about what you can expect for your project, depending on the size and scale, in Los Angeles. The ranges include everything from the first design to the last task.
Minor remodeling (bathroom, kitchen, etc.)
In case of single-room makeover generally not involving major structure, it takes about 2 to 5 months. This involves preparation, sourcing of material and building. Lead times for materials, such as custom cabinets and imported tile, can impact the schedule.
A significant remodel or extension.
Structural undertakings involving several rooms and additional square footage typically take 8 to 12 months or longer. Due to building code complexity, more extensive architectural design and engineering are warranted, which translates to a much bigger permitting process.
Custom Construction for New Homes
Constructing a new house in Los Angeles is an enormous task. Homeowners should realistically plan for 18 to 24 months (or perhaps longer) from an empty lot or teardown to moving in. This comprehensive timeline will be explained in greater detail.

Undoubtedly, the most undervalued aspect of any building activity is the pre-construction phase.
While no hammers swing during this time, it lays the groundwork for success and prevents costly delays later.
This is where you bring your concept to paper. You will cooperate with an architect to create blueprints, floor plans, and elevations. The structural engineers then formulate these into designs that meet applicable codes. Based on our experience, the back-and-forth revision process (to make sure it is exactly how you want it and meets local zoning) usually takes 1 to 4 months. If you rush this, it will cause trouble later.
Choosing the finishes, fixtures, and appliances may appear to be the fun part, but is a critical component of the timeline. Specialty materials like custom windows or imported stone can have lead times that range from weeks to months. Many homeowners wait to make decisions, often resulting in the items no longer being available when needed, thus halting the build.
Once plans are solid and material selection is largely done, it’s time to lock down a general contractor. The process of bidding, proposal evaluation, reference checks, and contract negotiation takes around one month. Do not just look at the dollar sign; having the details of the scope of work with an initial timeline is worth it.
The permitting process of the Los Angeles Department of Building and Safety (LADBS) is a complicated yet critical hurdle for any construction project in LA. Though many people may find it frustrating, with proper knowledge, you can do enough preparation.
After architects and engineers finish with their plans, they’ll submit them to the LADBS. This begins the process of plan check. The city's examination determines if your plans comply with building codes and other regulations. Response times for initial review vary. Some simpler projects may qualify for an over-the-counter review, whereas a major project will need a full review. This can take several weeks to months to get the first response.
It’s uncommon to have first-time permit approvals for projects, particularly larger ones. The city will send a ‘correction list’ to clarify which parts of your plan need changing. After adjustments are made by your architect and engineer, the revised plans get resubmitted. The back-and-forth of corrections and resubmissions is one of the most common areas of delay since each resubmission goes back into the queue.
Taking into account my past experience with LADBS, here are some realistic ranges:
It depends on the complexity of your project, whether your submittal was complete, and the current LADBS workload.
With the permits secured, it is time to start building. There are several logical steps taken during this stage of your plan. It is here your construction timeline Los Angeles becomes apparent.
The first task will be to prepare the land. This may entail demolishing existing structures, grading the site for drainage and excavation for the foundation, and then pouring the foundation. The soil conditions in Los Angeles vary from area to area, with some places being sandy while other places have large clays. In other words, the soil conditions may sometimes require specific engineering solutions, which can impact the initial timeframe.
The moment the foundation is laid down, we start the framing that builds your home. The “rough-in” trades install the basic systems: plumbing lines, electrical wiring, and HVAC ducting simultaneously or immediately afterwards. At this point, the city conducts critical inspections to ensure that these hidden systems are up to code before the walls are closed up.
This often tends to be the longest and most visually transforming stage. The process of closing up the exterior of the building entails the approach of first laying the roofing, siding, and windows. Once that is successfully done, we move inside and proceed with the drywall, insulation, flooring, painting, cabinetry, and finally installing all the fixtures and trim. There are several subcontractors coordinated at this stage.
LADBS will do final inspections to issue the Certificate of Occupancy as the project nears completion. You and your contractor will walk through the property at the same time to create a punchlist of small fixes or alterations.
In this article, we’ll give you a round-up of how long to build a house in LA where we’ll take you in chronological order through a standard custom new home project, unifying all the phases into a single recap.
The first six months involve nearly exclusive pre-construction activity. This entails getting an architect, working on plans with engineers, selecting extensive materials, and ultimately submitting your plans to the LADBS for approval. You’ll be six months away from the groundbreaking.
This six-month block often gets lost in the permitting queue at LADBS, working through correction lists, and resubmitting plans. The physical work can start after permits are finally issued. At this stage, there is a demolition (if required), site grading and excavation, and then pouring the foundation.
Construction of the main part is very fast here. Within 6 months of starting construction, the house is framed, all rough-in electrical, plumbing, and HVAC systems are installed, and the house is enclosed. After that, the interior and exterior finishes such as drywall, flooring, cabinetry, and paint transform the structure into a home.
In practical terms, designing and building a custom new home in Los Angeles typically takes around 18 to 24 months from the first meeting until move-in. Some very complex and/or unpredictable projects can go beyond this timeframe.
Even the best-thought-out project can run into issues. Having knowledge of these “X-factors” aids in proactive planning.
Delays in the international supply chain can hinder access to critical materials from specific windows to appliances and lumber.
Select materials early in the design process. To ensure timely completion of the project, order items with known long lead times, such as custom doors and high-end appliances, long and well before the demolition starts. Talk to your contractor about lead times.
LADBS inspectors can have hefty backlogs leading to delay in required inspections. Your plan may need to be edited or reworked at their request.
An experienced general contractor knows the nuances of scheduling inspections and how to work with the city. While delays are sometimes unavoidable, an experienced contractor can often overcome them more easily.
Always incorporate a buffer in your budget, typically 10-15% of the construction cost, as mitigation. By maintaining this reserve, we would be able to accommodate these surprises without impacting the project timelines.
Changing designs/materials on the way is generally a wrong move. Even a small change can set off a cascade of effects on ordering, scheduling, and inspections.
Mitigation: Make all design decisions and select all materials before construction. While minor changes may be required from time to time, please note that if a change order is significant, it will most probably extend your timeframe and increase your costs.
Even though your contractor manages everything, you as the homeowner must still get involved to keep the ball rolling.
A contractor will often request decisions regarding finishes, colors, or unforeseen field conditions. Responses must be prompt and clear. Resisting contractor decisions gets subcontractors stuck, which pulls the rest behind.
Establish your communication plan right from the start. To keep everyone on the same page, weekly check-in calls or on-site meetings are ideal. Taking the time to anticipate issues beforehand will prevent them from taking place.
Construction involves many complexities and contradictions in its execution. When you’ve properly vetted and hired your professionals, trust them. Use the proper channel to raise your concerns instead of trying to manage everything on site.
Prepared to Develop in Los Angeles?
The first step to a successful build is understanding the realistic construction project timeline Los Angeles offers. The pre-construction planning is extensive, and the LADBS permitting process is complicated. However, the heavy lift occurs during the active build and finishing stages. Each stage also takes considerable time. A big project is truly a marathon, not a sprint.

The duration of a construction project in Los Angeles varies significantly by scope. Minor remodels can take 2-5 months, significant renovations or additions typically span 8-12 months, and custom new home builds often require 18-24 months or more from initial design to move-in.
The LADBS (Los Angeles Department of Building and Safety) permitting process involves submitting plans for review, undergoing corrections, and resubmitting until approval. This phase is a common source of delays, typically taking 2-3 months for minor projects, 4-8 months for major renovations, and 6-12+ months for custom new builds.
Common construction delays in Los Angeles stem from several "X-factors," including supply chain issues for materials, backlogs and availability of city inspectors, unanticipated site conditions (like soil issues), and homeowner-initiated change orders during the build phase.
While some factors are beyond your control, you can help keep your project on track by making all design and material decisions early, responding promptly to contractor requests, maintaining open lines of communication, and trusting your vetted professional team throughout the process.
A minor remodel, such as a single room update, typically takes 2-5 months. In contrast, building a custom new home from an empty lot or teardown is a much larger undertaking, realistically requiring 18-24 months or more due to extensive design, permitting, and multi-phase construction.
It's advisable to start planning your construction project in Los Angeles as early as possible. The pre-construction phase, including architectural design, engineering, material selection, and contractor bidding, can take 3-6 months before any permits are even submitted.
