Securing a building permit in the bustling Metro Manila landscape is a rigorous process that demands technical precision. When you submit your plans to the Engineering & Building Official Department at the Mandaluyong City Hall, your blueprints undergo a meticulous review by city engineers and architects. Understanding the specific technical building permit requirements Mandaluyong enforces can be the difference between a swift approval and a frustrating series of revisions. This technical guide incorporates the latest standards taken from the City Hall last February 2026.

The Mandaluyong City Hall complex at Maysilo Circle is where the technical evaluation happens. Each department checks for compliance with the National Building Code of the Philippines and local city ordinances. To assist your engineers, you should download the actual list taken from the OBO to verify current scaling and layout rules.

Architectural Excellence and Accessibility

Architectural plans must be drawn to a scale of at least 1:100. Your submission must include:

1. Vicinity Map: A 500-meter radius for residential or a 2-kilometer radius for commercial projects.
2. Site Development Plan: Showing gridlines, orientations, setbacks, and parking layouts.
3. Visuals: A Perspective from a vantage point, at least four Elevations, and two Sections showing floor-to-floor heights.
4. Details: Reflected Ceiling Plans, Roof Plans, and Door/Window Schedules (at 1:50 scale).
5. Accessibility: Specific locations and detailed designs for accessibility facilities as per Batas Pambansa 344.

Civil and Structural Integrity

For any structure reaching two stories or higher, the City of Mandaluyong requires specialized engineering reports:

• Structural Analysis: Two copies of calculations for buildings 2-storey and above.
• Soil Quality: Two copies of a Boring Test for buildings 3-storey and above.
• Safety Reports: A mandatory Seismic Analysis and Structural Certification for renovations affecting stability.
• Plan Details: Foundation plans, framing plans, and detailed schedules of all structural elements.

Electrical and Sanitary Systems

The electrical folder must be distinct and highly detailed. It requires:

• Location Plan: Showing the Service Drop, MERALCO pole location, and meter details.
• Technical Layouts: Legend of symbols, Electrical Layout, and a Schedule of Loads.
• Calculations: Two copies of Electrical Design Analysis, including Voltage Drop and Short Circuit Calculations.
• Fire Safety: Dedicated plans for Fire Alarm Circuits and a Single-Line Diagram.

Sanitary and plumbing documents involve:

• Detailed plans for water supply, sewage drainage, and storm drainage.
• Design analysis for water purification or sewage treatment plants if applicable.
• Plumbing layouts at a minimum scale of 1:50.

Geodetic Surveys and Final Submissions

Geodetic documents establish the precise boundaries of your lot to prevent encroachments in the NCR region. You must submit two copies of Lot Survey Plans which include:

• The official Lot Plan.
• A Relocation Survey Plan and Report.
• The Line and Grade report.

Navigating the Engineering & Building Official Department at the Mandaluyong City Hall requires patience and professional expertise.
