Interior Remodeling & Design

Not all interior remodels will require a permit. It depends on the scope of the project. Basic cosmetic upgrades like flooring or cabinetry typically do not require permits. However, any structural, plumbing, or electrical work will require a permit. The good news is that we know when permits are needed and when not, and we handle the entire process. On your end, you simply tell us what you want. Then, we make it happen.

Most of the time, interior remodeling will not require any zoning approval. Zoning clearances are needed only for projects that update the exterior footprint of your home. However, an interior remodel that expands or converts a space may need zoning clearance to confirm it adheres to use and safety standards. We figure all of this out for you, using local expertise to guide the process and prevent any delays.

Communities with a Homeowners Association (HOA) may restrict some interior projects. However, you usually only need HOA approval for projects that would affect utilities or shared walls. We always take a client’s HOA regulations into account when designing projects. For basic cosmetic upgrades, HOA limitations often do not apply.

Interior remodeling can happen year-round! Since all work typically takes place indoors, you need not consider the weather. If you plan both exterior and interior renovations, you may want to consider seasonal advantages and disadvantages when moving forward with your project.

If a home inspector or city official discovers unpermitted work in your Los Angeles home, it can create serious problems. You may be required to stop all current construction, pull the proper permits after the fact, and, in some cases, tear down or redo the work entirely so it can be inspected properly. This process — called a “retroactive permit” or “permit after the fact” — can cost significantly more than getting the permit upfront.
Beyond the cost, unpermitted work can also affect your home’s value, make it harder to sell, and may cause your homeowner’s insurance to deny certain claims.

The kitchen is consistently the most expensive room to renovate in any home. A mid-range kitchen remodel in Los Angeles typically runs between $30,000 and $80,000, while a high-end kitchen renovation can easily exceed $100,000 or more.
Why so costly? Kitchens involve nearly every trade — plumbing, electrical, cabinetry, countertops, appliances, flooring, and lighting — all in one space. Custom cabinets, stone countertops like quartz or marble, and professional-grade appliances drive costs up quickly. The good news: a well-done kitchen remodel offers one of the best returns on investment when it comes time to sell your home.

Across all types of home renovations, labor costs are usually the single biggest expense — often making up 40% to 50% of the total project budget. Skilled tradespeople such as electricians, plumbers, and structural contractors charge premium rates, especially in a high-demand market like Los Angeles.
After labor, the next most expensive elements tend to be structural changes (like removing load-bearing walls), plumbing and electrical upgrades, and high-end materials such as hardwood flooring, custom millwork, or luxury tile. If your project involves an addition or major layout change, foundation work can also push costs significantly higher.
