Article 33 the interval of multi-layered and low-rise residential buildings shall not be smaller than what is stipulated in the Blank 6-1.
The width of the gable for the vertically-set residential building shall not be larger than 14m; when the gable width is larger than 14m, its interval is controlled according to the horizontally-set residential building; point residential building shall not be connected, and for the special circumstance that requires connection, the connected number shall not be more than 2.
For the building interval that is calculated according to the Blank 6-1, but fails to meet the requirements of firefighting interval or access, it shall be controlled according to the actual demand of firefighting interval or access.
Article 34 the interval of the residential buildings that are neither vertically-set nor horizontally-set, shall be controlled according to the computational principle 2 in the appendix
Article 35 the interval of the high-rise residential building whose fa?ade width doesn’t exceed 25m and other residential buildings, shall be controlled according to the computational principle 3 in the appendix, and shall be in compliance with the Article 32.
Article 36 the interval of the high-rise residential building whose fa?ade width exceeds 25m and other horizontally-set residential buildings, shall be executed according to the stipulations of the Blank 6-1.
Article 37 the interval between the gables of high-rise building and the multi-layered and low-rise residential buildings shall be controlled according to the stipulations of the “Firefighting Specification of Architectural Design for High-rise Civil Buildings” (GB50045-95). However, for those whose gable has residents and windows, the interval shall not be smaller than 13m.
Article 38 the interval of non-residential building and residential building shall be in compliance with the following stipulations:
(I) For the non-residential building located to the south or west east of the residential building, the building interval shall be executed according to the Article 32 to the Article 37;
(II) For the non-residential building located to the north of the residential building, the building interval shall be executed according to the Article 40;
(III) The gable interval of non-residential building and residential building shall be controlled according to the Firefighting Safety Specification of Architectural Design.
Article 39 the interval between in-patient department of hospital, dormitory building of sanatorium, kindergarten, nursery and the teaching buildings of preliminary, middle schools and universities and the neighboring building on south, shall guarantee the full-window sun-exposing effective time of the above-mentioned shaded buildings on winter solstice is not less than 3 hours. Meanwhile, beyond the second ring road, it shall be not less than the 1.3 times of the neighboring building’s height; Within the second ring road, it shall be not less than the 1.2 times of the neighboring building’s height.
Article 40 Interval of Non-residential Buildings (except the non-residential buildings listed in the Article39)的interval,应当shall be in compliance with the following stipulations:
(I) interval of the horizontally-set high-rise building
1. For those with north-south orientation, it shall be not less than the 0.4 times of the south building’s height, and the minimum value is 20m;
2. For those with east-west orientation, it shall be not less than the 0.3 times of the higher building’s height, and the minimum value is 13m.
(II) When the high-rise building is horizontally set with multi-layered and low-rise building, the minimum value of the high-rise building’s interval on north is 13m; the minimum value of the high-rise building’s interval on south is 20m.
(III) The interval of the horizontally-set multi-layered building shall not be less than the 0.8 times of the south building or the higher building’s height, and shall meet the demand of firefighting safety interval.
(IV) For the neighboring buildings, if one is a residential building, the relevant stipulations on residential building interval in the Regulations shall be followed.
(V) the urban planning administrative competent departments can consider the special requirements of firefighting, transportation, sanitation, and environmental-protection, engineering pipeline laying, building protection and construction safety etc, and make special stipulations on the interval of non-residential buildings.

垂直布置的居住建筑山墙宽度应当不大于14m；山墙宽度大于14m时，其间距按平行布置的居住建筑控制；点式住宅不宜进行拼接，特殊情况确需拼接的，拼接不得超过二幢。
对按表6-1规定计算的建筑间距不能满足消防间距或通道要求的，应当按消防间距或通道的实际要求进行控制。
第三十四条 居住建筑既非平行也非垂直布置时的间距，按照附录计算原则二进行控制。
第三十五条 面宽不超过25m的高层居住建筑与其它居住建筑的间距，按照附录计算原则三进行控制，且应当符合本规定第三十二条规定。
第三十六条 面宽超过25m的高层居住建筑与其它居住建筑平行布置的间距，按照表6-1的规定执行。
第三十七条 高层建筑与多、低层居住建筑的山墙间距，按照《高层民用建筑设计防火规范》（GB50045—95）规定控制，但山墙有居住开窗的，间距不小于13m。
第三十八条 非居住建筑与居住建筑的间距，应当符合下列规定：
（一）非居住建筑位于居住建筑南侧或东西侧的，其间距按照本规定第三十二条至第三十七条的规定控制；
（二）非居住建筑位于居住建筑北侧的，建筑间距按照本规定第四十条规定执行；
