Design Made Simple – From Site Visit to Permit Approval

Building a house, ADU, or room addition can feel overwhelming—especially for homeowners who are not familiar with construction processes or building codes. With numerous requirements and complex regulations to follow, it’s essential to have the right professionals guiding you every step of the way.

JYL Architect makes the process easier. It begins with a site visit and a thorough design and structural consultation, tailored to your specific needs and the existing conditions of your home. During this visit, JYL will also take precise initial measurements to inform the design process.

Using the information gathered, JYL Architect will develop an effective and functional architectural plan—carefully balancing aesthetics, efficiency, and compliance with local regulations. Once you approve the initial concept, they will finalize a complete set of architectural drawings. These include approximately 20 plan sheets, such as:

  • Site Plan
  • Floor Plan
  • Elevation Drawings
  • Roof Plan
  • Cross Sections and More

Next, JYL will submit the full plan set to the appropriate city or county building department and handle all communication throughout the approval process. In most cases, cities request a few corrections based on updated codes or specific local requirements. JYL will take care of all revisions and re-submissions at no additional charge, ensuring the plan is brought to final approval smoothly.

Once approved, you or your contractor will be ready to pull the permit and begin construction on the project you’ve been planning.

Special Offer: $2,999 Flat Rate

This limited-time price includes:

  • On-site visit and design consultation
  • Full architectural drawings
  • Plan submittal to the city

  • Energy calculations (Title 24): Approximately $500

Aside from these, JYL Architect will deliver an efficient, code-compliant, and beautifully designed plan within approximately 2–3 weeks.
