Construction planning includes permit coordination.
Distinguish known scope from work needing review
For an Altadena project, bring any existing plans and assessments along with the proposed improvements. Identify what has already been designed and what still needs investigation or agency review. This helps the construction discussion stay grounded in the property’s actual conditions without treating an early concept as a final scope.
