Code (NBC)? Is it still the Law?

__________________________________________________________________________________________________________________________________


1. The present NBC was promulgated 19 March 1977 as PD 1096by President FM; its various Implementing Rules and Regulations (IRRs)were issued by the MPWTC until 16 July 1979; in 1992, only the IRR section

on Permit Fees were amended;

2. In the year 2000, the DPWH re-organized the Board of Consultants (BoC)

composed of representatives of accredited professional organizations (APOs)and reconstituted the Building Research and Development Staff (BRDS) intothe NBC Review Committee (NBCRC);

3. the BoC was headed by a past UAP President (Angel Lazaro, Jr.)

and 36 other member-professionals took part in the 3-year effort to

revise only the IRR, which was signed by the DPWH Secretary on 03 Nov2004, published April 2005 and which took effect 02 May 2005;

4. as of 2005, PD 1096 (NBC) is still the only law on buildings asit was neither amended nor repealed;

be asked to help disseminate information on the IRR; and

b. issuance of the manual of procedure for use by theBuilding Officials tasked to enforce the 2005 R-IRR; and

2. sometime in 2006, crafting of thebill

(the Building Law)

that shall fully repeal PD 1096 (NBC) and fully assimilate theRevised IRR of 2005, should be completed; however, this newlegislative effort may extend to 2007 and beyond;

setbacks may be somewhat relaxed for new construction withinbuilt-up areas or for renovation/ rehabilitation projects;2. The Revised IRR integrates general design and physical

planning concerns, particularly on the matter of the developmentand usage of RROWs and ROWs and their collective effect on thedetermination of building bulk inside properties facing RROWs;

3. The building permit shall become a general permit to be firstsupported by ancillary or accessory permits; and

4. Architectural & Structural Permits are types of ancillary permits.

control and development potentialactually mean (under

the 2005 Revised IRR of the NBC/ PD 1096)?

__________________________________________________________________________________________________________________________________


Carrying Capacity of Lot the optimized extent of physical development that may beintroduced into the lot without causing undue damage, effects or hardship on the end-usersof the proposed development or on neighboring occupants, entities, properties, lands,developments or the environment (whether man-made or natural) and with the proposedbuilding/structure capable of being supported by existing utility, transportation and service

systems or by proposed expansions/upgrading of such systems within the immediate future;

Development Control (for Lots and Buildings/ Structures) a set of inter-actingregulations concerning the physical utilization of a lot and likewise governing theplanning/design of spaces and/or the use/occupancy of a building/structure to be introduced(or already existing) on a lot; development controls help determine in detail the development

potential and/or the carrying capacity of all lots and/or of proposed developments on lots;and

Development Potential of Lotthe maximum extent of physical development that may beintroduced into the lot, i.e., the erection of the proposed buildings/ structures, after fullcompliance with the applicable regulations that need to be satisfied, specifically those foundin the Code, i.e., the PNBC.

July 2005, Metropolitan Manila Member, DPWH Board of Consultants (2002-2005)

To prevent illegal rule insertions in the printed version of

the 2005 Revised IRR(which happened so many times in the past toprevious editions of the NBC IRR), the following steps should betaken:

a) the DPWH must be the only and solely designated

copyright holder to the 2005 Revised IRR;b) the only official source of the document (in either hard or

soft versions) should be the DPWH; and

c) the only official publisher should be the National PrintingOffice (NPO) located along EDSA in Quezon City (between East Ave.& Quezon Blvd.), i.e., not the National Bookstore!
