A so-called input plan is used by the competent authority to review your building project: A building permit for a new building is only issued if the building application submitted is complete and certain requirements are met. Demolition, structural changes or a planned change in use for an existing building must also be requested using an input plan. In addition to the application, a number of other documents are required in this context. Find out what to look out for if you want to create your own input plan on your own.

What is an input plan and what documents does it contain?

Many people are probably better familiar with the input plan under the term “building application”. In this context, however, one often speaks of “approval planning”. The input plan has the function of presenting the desired building project and the usage requirements in a comprehensible and complete manner. In this way, the responsible office not only checks whether all building law requirements are met – it also checks whether the property is suitable for the building project and whether neighbors or the surrounding area could possibly be affected.

As a whole, the input plan consists of several documents. The scope and the individual components do not only differ from state to state; individual requirements are usually made at the community level. Before submitting an application, it is therefore advisable to obtain information from the responsible building authority. Basically, most of the documents and information listed below belong to it:

  • – Building application form (filled in completely and correctly and signed)
    – Extract from the site plan of the land registry office
    – Calculation of costs for the construction project
    – Area calculation to differentiate between useful and living space
    – Calculation of the area of ​​the building and the number of floors planned
    – Description of the construction project
    – Statistical questionnaire
    – Application for house and property drainage
    – Site plan with noted building project
    – Information on the spacing area on a 1: 500 scale
    – Construction drawings of the floor plans, building views and sections on a 1: 100 scale
    – Evidence of planned statics, heat, noise protection and fire protection measures
    – Proof of required parking spaces

In municipalities that have particularly popular building locations, additional requirements may be expected. These include, for example, guidelines that must be followed in terms of size and appearance. The best way to find out what is allowed and what is not by researching the community website or in a personal consultation.

As soon as the entry plan is complete, it must be submitted in triplicate. In the ideal case, it is not the client himself who submits the application, but a draftsman with building authorization, usually a civil engineer or an architect. Based on his expertise, he can vouch for the correctness of the information provided.

Which deadlines have to be observed?

It usually takes four to twelve weeks before a construction plan is approved. Since the construction site has come to a standstill in advance, the submission plan should be submitted in good time. Furthermore, it would be wise to allow time for a correction loop if changes in the building application become necessary. When planning, make sure that there are phases in which, due to seasonal factors, many applications are received in parallel – the start of construction can also be delayed due to longer waiting times.

Despite the circumstances described, you should not plan too far into the future, as building permits are usually limited to three years. If this period is exceeded, a new application for the construction project is required, in which all components are fully checked again. If construction projects are protracted under special circumstances, the deadlines can be exceeded – but be careful: there is no definitive legal claim.

Can costs already be saved based on good planning?

A particularly important topic in every construction project is minimizing costs. Many builders are therefore justifiably asking themselves whether they can already make use of savings potential in the course of the planning phase. While there are no opportunities to save on the fees that arise from visits to the authorities, personal contributions during planning can actually pay off later.

For example, anyone who puts as precise a concept as possible for the building project on paper makes the work of the architect or site manager easier. So distribute the rooms, define the desired sizes and determine the respective functional orientation. In this context, structural features such as the desire for a fireplace should also be taken into account and clarified. Therefore, exchange ideas with the implementing service provider and let the expert give you the assessment. The better your template, the lower the effort, working time and therefore also the costs for the professional creation of the construction drawing. Hourly billing of services often offers a price advantage compared to flat-rate packages.

Another advantage of planning as precisely as possible is that unexpected changes, which often call for unplanned costs, are largely avoided. Or you can react better to this. Finally, by planning as efficiently as possible and doing your own work, ideally you save valuable processing time with the authorities.

What other advantages result from personal contributions?

Getting professional help on board when creating the input plan is generally not the wrong way for building owners. After all, you can rely on the fact that all building regulations with regard to stability as well as heat and sound insulation are met. Site-specific regulations that make the creation of the input plan more difficult are also taken into account. With a little luck, you will also save valuable time processing the application and – as already mentioned – you will not experience any nasty surprises in the event of subsequent changes.

By doing your own work, you also have a very good overall view of the construction project. It is not only finances that play an important role – being involved in as many work steps as possible and dealing with authorities independently gives you a feeling of security and creates a better understanding of the world of construction. Furthermore, at certain points it is easier to estimate the extent to which the amateurishly designed elements can actually be implemented. You should definitely see the exchange with the authorities and contractors as an opportunity to create your input plan correctly and completely. This is the only way to bring your own wishes and the building regulations under one roof and to be all the more pleased with the end result.
