Local planning · Costa Mesa
We Know How Costa Mesa Works
Start with the local review process. Costa Mesa uses TESSA for digital permit applications. We coordinate the project information and drawings for the proposed work, whether the goal is an interior remodel, an addition or an outdoor structure. See the Costa Mesa building permit guidance for current information.
Plan the interior before selecting finishes. For your Costa Mesa kitchen or bathroom remodel, we review the layout, wall changes and proposed plumbing, electrical and ventilation work. We help coordinate the design and engineering needed for the agreed scope, including any required energy documentation.
Bring the outdoor plan together. A patio cover, outdoor kitchen, pool, spa or retaining wall needs to be considered with the site layout, drainage and utilities. We check the requirements for the proposed work before locking in locations and materials. For an ADU or addition, we also review how the new space connects to the existing property.
One team through the next steps. We help Costa Mesa homeowners move from design and engineering through permit coordination and construction. Applicable HOA approvals, city or county review and inspection stages are built into the project planning. Already have designs or plans? We can work with those, too.

Before we begin
Planning your Costa Mesa remodel: questions, answered.
Do I need a permit for a kitchen or bathroom remodel in Costa Mesa?
Most cosmetic kitchen and bathroom updates like replacing cabinets, countertops, or fixtures do not require a permit in Costa Mesa. However, any work involving structural changes, moving walls, relocating plumbing, or adding electrical circuits does require a permit from the Costa Mesa Building Safety Division. We handle all permit applications and plan check submissions for you through the city's TESSA portal.
How do I get a permit for a patio cover or backyard structure in Costa Mesa?
In Costa Mesa, patio covers, pergolas, and shade structures over 200 square feet require a building permit. Solid roof patio covers also require structural engineering drawings. Our team prepares all documentation, submits through the TESSA permit portal, and manages the full inspection process so you don't have to.
Can I build an ADU on my Costa Mesa property?
Yes. Costa Mesa follows California state ADU laws, which allow most single-family properties to add at least one ADU and one Junior ADU. Detached ADUs require a minimum 4-foot setback from rear and side yard boundaries. The city also offers a Pre-Approved ADU Program that can speed up the approval process significantly. We handle the full design, permit submission, and construction of ADUs in Costa Mesa from start to finish.
How much does a backyard remodel cost in Costa Mesa?
A full backyard remodel in Costa Mesa (about 2,000 sq ft) usually starts around $40,000 to $70,000. From there the price depends on the design, like adding a pool, an outdoor kitchen or BBQ island, a fire pit, and new landscaping. We provide a detailed itemized estimate after a free on-site consultation and 3D design session.
What outdoor remodeling projects are most popular in Costa Mesa?
The most popular outdoor projects we complete in Costa Mesa include paver patio installations, aluminum and wood patio covers, outdoor kitchen and BBQ island builds, artificial turf installation, fire pit and sitting area construction, and pool installations. Costa Mesa's year-round mild climate makes outdoor living spaces one of the highest-ROI investments a homeowner can make.
How long does a kitchen remodel take in Costa Mesa?
A typical kitchen remodel in Costa Mesa takes 6 to 10 weeks from permit approval to completion, depending on the scope of work. Projects involving structural changes, custom cabinetry, or material lead times may take longer. We provide a detailed timeline before work begins and keep you updated throughout the project.
Is HQ Remodeling licensed to work in Costa Mesa?
Yes. HQ Remodeling & Design Inc holds California General Contractor License #1041842 and is fully licensed, bonded, and insured to perform remodeling work in Costa Mesa and throughout Orange County.
