Local planning · Rancho Santa Margarita
We Know How Rancho Santa Margarita Works
Start with the local review process. Building applications and zoning information are available through the city. If your home is subject to association rules, we also review the relevant architectural requirements so the proposed materials and exterior changes can be coordinated. See the Rancho Santa Margarita Building and Development for current information.
Plan the interior before selecting finishes. For your Rancho Santa Margarita 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 Rancho Santa Margarita 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.
