Residential inspectors scrutinize projects for construction or modification of houses, townhouses, additions, alterations, demolitions, repairs, and various accessory structures.

After you obtain the permits you must request mandatory inspections to ensure that permitted work on the project is approved and the building or structure is ready for use or occupancy.

Work is inspected in the sequence described for each project type.

The permit must be on site at the project. Be certain that your project is clearly marked with a lot number or address.

For all inspections, a set of approved plans, if any, stamped by Montgomery County must be on the job site for inspector’s review.

USEFUL INFORMATION AND LINKS

When a permit is issued, a Notice of Required Residential Inspections is attached to the approved plans listing the required building inspections for the permit type. Similarly, a Notice of Required Residential Deck Inspections is attached to the deck approved plans. Some mechanical, fire sprinkler and electrical inspections are prerequisite for scheduling building inspections (and vice versa) and are cross referenced accordingly in the required inspections for each project type. Furthermore, please consult the description of all residential inspections.

Montgomery County residential inspectors are cross trained in building, mechanical and electrical inspections, therefore the close-in and final building, electrical, and mechanical must be scheduled at the same time for the same date. However, close-in and final inspections must be requested under the relevant Building, Electrical and Mechanical Permits. If all trades are not ready, the inspector will disapprove the scheduled inspections.

When a Building Permit Notice is issued for your project, you must post it within 3 calendar days after the release date and it must remain posted for 30 calendar days. No other inspections will be performed prior to approval of the posting requirements of the sign.

Before you dig call MISS UTILITY 1-800-257-7777 (2-day notice is required). Please note that the Maryland High Voltage Line Act prohibits any person or object from getting closer than 10 feet to high voltage power lines.

You can learn more about other inspections that may be applicable to your project type by seeing our index of inspections .

If an owner refuses access within a reasonable amount of time after the house is completed, the building official may close the permit file but, this action will not relieve the owner of any obligation to comply with applicable building codes.

If you have job specific questions during construction, please call the inspector assigned to the area in which the project is located using our  Find My Inspector application.
